Description

  Embodiments described herein relate generally to a clinical testing apparatus.

  A clinical test is performed in order to objectively evaluate the state of a subject such as a patient. A clinical laboratory apparatus is mainly used for this clinical examination. An example of a clinical testing apparatus is an automatic analyzer.

  An automatic analyzer is a device that mixes a specimen such as blood or urine with a reagent and measures components of the mixed solution. Some automatic analyzers are capable of analyzing a single sample with a plurality of measurement items (hereinafter sometimes simply referred to as “items”). Examples of measurement items include biochemical test items and immunological test items.

  For example, the automatic analyzer is requested to inspect a plurality of measurement items on a sample such as blood of a patient. The automatic analyzer performs measurement based on this request. The automatic analyzer performs analysis by performing predetermined processing on data after measurement (hereinafter, sometimes referred to as measurement data). The automatic analyzer displays and outputs the analysis result on the display unit.

  In order for the automatic analyzer to inspect one measurement item, a chemical reaction time is required. This chemical reaction time generally requires 3 to 10 minutes. In addition, many pathological conditions are not determined by a single measurement item, but are determined by comprehensively examining test results of a plurality of measurement items. Therefore, automatic analyzers often measure 10 to 20 items for one specimen.

  Examples of the type of the subject corresponding to the sample include a general health check-up recipient and a patient. In particular, there are various types of patients such as outpatients, inpatients, urgently transported patients, and the like. Among specimens corresponding to these patients, there are cases where it is desired to pay attention to the measurement results obtained by the automatic analyzer due to various causes. This measurement result is, for example, the result of examination of a specific patient, the result of a specific measurement item, or the like.

  Therefore, in order to specify such a patient, the laboratory technician needs to identify the patient-specific ID, name, ward information, etc., and carefully check the data of the corresponding measurement item.

JP 2000-162214 A

  However, the automatic analyzer measures several hundred samples per day. Further, the analysis result values of several tens of items are reported (output) every several seconds to several tens of seconds per sample in the automatic analyzer. In such a situation, it is labor intensive and erroneous for the operator to grasp the measurement result of the sample corresponding to a specific patient.

  This embodiment is intended to solve the above-described problem, and an object thereof is to provide a clinical test apparatus capable of notifying the outside of the measurement state of a specific sample in a clinical test.

  In order to solve the above-described problem, the clinical examination apparatus according to the embodiment includes an identification unit, a detection unit, an output unit, and an analysis unit. The identification unit acquires the identification information of the sample container, and the sample corresponding to the identification information of the sample container from the identification information of the sample container and the correspondence information between the identification information of the sample container set in advance and the identification information of the sample Get identification information for. The detection unit receives the identification information of the sample and detects the sample container in which the specific sample is accommodated by collating the identification information of the sample with the identification information of the specific sample set in advance. The output unit outputs the detection information when the sample container is detected by the detection unit. The analysis unit dispenses the specimen contained in the sample container into the reaction container, and measures the component of the liquid containing the specimen.

[Functional configuration of automatic analyzer]
As shown in FIG. 1, the automatic analyzer 10 includes an analysis unit 24, an analysis control unit 25, a data processing unit 30, an identification unit 40, a storage unit 50, a detection unit 60, and a system control unit 70. The operation unit 80 and the output unit 90 are provided. A storage unit 200 is connected to the automatic analyzer 10.

[Analysis control section]
The analysis control unit 25 includes a mechanism unit 26 and a control unit 27. The analysis unit 24 is controlled by the analysis control unit 25. The mechanism unit 26 is configured to include a motor, a gear, and the like, and drives each unit of the analysis unit 24 by generating a driving force and transmitting it to each unit of the analysis unit 24.

[Analysis Department]
The analysis unit 24 generates a mixed solution including the specimen and reagent liquids, and measures the components of the mixed solution. Details of the configuration of the analysis unit 24 will be described below.

[Configuration of analysis unit]
FIG. 2 is a diagram illustrating details of the configuration of the analysis unit 24 and a control configuration. The configuration of the analysis unit 24 will be described in detail with reference to FIG.

  The analysis unit 24 measures the absorbance of the mixed solution of the specimen and the reagent, and outputs measurement data. The measurement data is, for example, absorbance data. The measurement data includes preliminary measurement data in addition to sample data. Examples of the preliminary measurement data include calibration data, accuracy control data, sample blank data, reagent blank data, and the like. The sample data is data in which the sample is blood, plasma, or the like of the subject in the above absorbance measurement.

  The control unit 27 controls the driving of each unit included in the analysis unit 24 by instructing the mechanism unit 26. Each unit includes a first reagent container 2, a second reagent container 3, a reaction container 5, a disk sampler 6, and an arm 14 (sample dispensing probe 7, first reagent dispensing probe 8, and second reagent dispensing probe 9). Each arm).

[Sample container]
A specimen (sample) is stored in the sample container 61. The sample container 61 is mounted on a rack 63 mounted on a rotatable circular disk sampler 6 and / or a rack sampler 65. The disk sampler 6 and the rack sampler 65 convey a desired specimen to a suction position by the sample dispensing probe 7.

  A sample container ID for identifying the sample container 61 is attached to the sample container 61. By associating the sample container ID with the subject ID, the identification unit 40 can identify which subject the sample in the sample container 61 is collected from. Examples of the ID include a UID (Unique ID).

  Regarding the conveyance of the sample container 61, first, a case where the sample container 61 is placed on the disc sampler 6 will be described. In the storage unit 50, correspondence information between the sample container and the placement position is stored in advance. The correspondence information between the sample container and the placement position is correspondence information between the sample container ID and the position of the disk sampler 6 on which the sample container 61 corresponding to the sample container ID is placed. For example, a mounting position number for identifying the mounting position is assigned to the disk sampler 6. At this time, the correspondence information between the sample container and the placement position in the disk sampler 6 is, for example, information in which the sample container ID and the placement position number are associated with each other.

  It is also possible to identify the sample container 61 placed on the disk sampler 6, obtain identification information of the sample container 61, and generate correspondence information between the sample container and the placement position based on this information. Correspondence information between the sample container and the placement position is similarly stored in the storage unit 50. In this case, the correspondence information between the sample container and the placement position is generated as follows, for example.

  The analysis unit 24 includes a first reading unit 62A and a second reading unit 62B, which are sample container identifier reading units 62. The sample container 61 is provided with a sample container identifier for identifying the sample container ID. When the sample container 61 is placed on the disk sampler 6, the first reading unit 62 </ b> A reads the sample container identifier provided in the sample container 61. This sample container identifier is, for example, a label. For example, the label is provided with a barcode, an IC chip, and the like.

  The identification information of the sample container 61 read by the first reading unit 62A is associated with the position information of the disk sampler 6 on which the sample container 61 is placed by the association unit 43 described later. This correspondence information is stored in the storage unit 50 as correspondence information between the sample container and the placement position.

  Next, a case where the sample container 61 is placed on the rack sampler 65 will be described. The rack sampler 65 includes a conveyance path 64. A plurality of racks 63 having a plurality of sample containers 61 are placed on the transport path 64. On the rack 63, for example, sample containers 61 are placed in a line. The rack 63 can move on the conveyance path 64. The moving direction of the rack 63 is, for example, a direction orthogonal to the direction in which the sample containers 61 are arranged.

  The rack 63 provided in the rack sampler 65 is transported to the vicinity of the sample dispensing probe 7 of the analysis unit 24 by moving on the transport path 64. The rack 63 transported to the vicinity of the sample dispensing probe 7 moves, for example, in the direction in which the sample containers 61 are arranged. By this pitch movement, a desired specimen can be transported to the suction position by the sample dispensing probe 7.

  When the rack sampler 65 is transported to the vicinity of the sample dispensing probe 7, the second reading unit 62 </ b> B reads the sample container identifier attached to the sample container 61. The identification information of the sample container 61 read by the second reading unit 62B is associated with the position information of the rack sampler 65 on which the sample container 61 is placed by the association unit 43 described later. This correspondence information is stored in the storage unit 50 as correspondence information between the sample container and the placement position. The position information of the rack sampler 65 includes information on the sample container 61 in the rack 63 and information on the rack 63 in the rack sampler 65. The rack sampler 65 is configured to be able to read the sample container identifier. The rack sampler 65 is assigned a rack identifier, for example. For example, when all the specimens stored in the sample container 61 placed on the rack sampler 65 belong to the same subject, the rack identifier can be handled as the sample container identifier. That is, the rack identifier is the sample container identifier of the sample container 61 placed on the rack sampler.

[Reagent container]
The reagent container 4 is placed in the first reagent container 2 and the second reagent container 3. The reagent container 4 stores various first reagents that selectively react to measurement items of the specimen or various second reagents that are paired with the first reagent.

  The reagent container 4 containing the first reagent is placed in the first reagent store 2, and the reagent container 4 containing the second reagent is placed in the second reagent store 3. The first reagent store 2 and the second reagent store 3 contain a rotatable circular reagent rack 1. Each reagent container 4 is accommodated in the reagent rack 1 in a ring shape.

[Reaction vessel]
The reaction vessel 51 is placed in the reaction chamber 5. Samples and reagents are dispensed into the reaction container 51. The reaction vessel 51 is placed in a circular shape on a rotatable circular cassette member (not shown). A reaction container ID for identifying the reaction container 51 is attached to the reaction container 51.

  The storage unit 50 stores in advance reaction container correspondence information in which the reaction container ID is associated with the position information of the reaction container 51 corresponding to the reaction container ID. The position information of the reaction vessel 51 is the position information of the reaction chamber 5 in which the reaction vessel 51 is placed.

  A reaction container identifier reading unit 52 is provided in the vicinity of the reaction chamber 5. The reaction vessel 51 includes a reaction vessel identifier for identifying the reaction vessel ID. This reaction container identifier is, for example, a label. For example, the label is provided with a barcode, an IC chip, and the like.

  The reaction chamber 5 has a window (not shown) that can identify the reaction vessel identifier, and the reaction vessel identifier reading unit 52 can read the reaction vessel identifier through this window. When the reaction vessel 51 is transported to the position of the reaction vessel identifier reading unit 52 by rotating the reaction chamber 5, the reaction vessel identifier reading unit 52 reads the reaction vessel identifier attached to the reaction vessel 51.

  The read information on the reaction vessel 51 is associated with the position of the reaction chamber 5 on which the reaction vessel 51 is placed by an association unit 43 described later. This correspondence information is stored in the storage unit 50 as reaction container information. Reading by the reaction container identifier reading unit 52 is performed for all the reaction containers 51 placed in the reaction chamber 5.

  In addition, the sample and the reagent are dispensed into the reaction container 51 by using the sample dispensing probe 7, the first reagent dispensing probe 8, and the second reagent dispensing probe 9.

[Sample dispensing probe]
The sample dispensing probe 7 sucks the specimen from the sample container 61 transported to a specified suction position by the rotation of the disk sampler 6 or the movement of the rack 63 by the rack sampler 65. The sample dispensing probe 7 discharges the aspirated sample into the reaction container 51 that has been transported to a specified discharge position. At this time, the associating unit 43 associates the specimen ID for identifying the specimen with the reaction container ID for identifying the reaction container 51 from which the specimen has been discharged. By this association, for example, a table indicating correspondence information between specific specimens and reaction containers as shown in FIG. 8 is created.

[First reagent dispensing probe]
The first reagent dispensing probe 8 aspirates the first reagent from the reagent container 4 that has been transported to the specified suction position by the rotation of the reagent rack 1 of the first reagent storage 2. The first reagent dispensing probe 8 discharges the first reagent sucked into the reaction container 51 conveyed to a specified discharge position.

[Second reagent dispensing probe]
The second reagent dispensing probe 9 sucks the second reagent from the reagent container 4 transported to the specified suction position by the rotation of the reagent rack 1 of the second reagent storage 3. The second reagent dispensing probe 9 discharges the second reagent sucked into the reaction container 51 transported to a specified discharge position.

  A stirring unit 11, a photometric unit 12, and a cleaning unit 13 are further provided on the outer periphery of the reaction chamber 5. The reaction container 51 into which the sample and the reagent are dispensed is sequentially transported to the stirring, measuring, and cleaning positions of the stirring unit 11, the photometry unit 12, and the cleaning unit 13 by rotating a cassette member (not shown).

[Agitator unit]
The agitation unit 11 is an agitation unit that agitates the mixed solution of the specimen and the reagent (first reagent and second reagent) in the reaction vessel 51 stopped at the agitation position for each cycle.

[Washing unit]
The cleaning unit 13 aspirates the mixed liquid that has been measured in the reaction container 51 stopped at the cleaning / drying position, and cleans / drys the reaction container 51.

[Metering unit]
The photometric unit 12 is a measuring unit that measures the absorbance of the mixed solution stored in the reaction vessel 51 at the photometric position. The photometry unit 12 measures the absorbance of the mixed solution and then outputs the measurement data to the data processing unit 30. The data processing unit 30 obtains the concentration of the mixed solution from the absorbance based on the calibration curve. Thereby, it becomes possible to measure the component of a liquid mixture.

[Data processing section]
The data processing unit 30 includes a calculation unit 31 and a data storage unit 32. The data processing unit 30 receives the measurement result of the component of the mixed solution output from the analyzing unit 24, and calculates the concentration of the specific substance in the mixed solution. The data processing unit 30 creates analysis data, calibration data, and the like by this calculation processing, and stores these data in the storage unit 50 and the like as necessary.

  When there are a plurality of types of specific substances, the automatic analyzer 10 sets measurement items for each specific substance and performs measurement using the plurality of measurement items. Furthermore, the data processing unit 30 calculates the concentration of the specific substance for each measurement item and creates analysis data and the like. Measurement data including the analysis data is output.

[Calculation section]
The calculation unit 31 processes the standard data and sample data output from the photometry unit 12 of the analysis unit 24 to create calibration data, analysis data, and the like for each measurement item.

[Data storage section]
The data storage unit 32 stores calibration data, analysis data, and the like created and processed by the calculation unit 31 as necessary.

  Further, the data processing unit 30 may include a graph creation unit (not shown). The graph creation unit creates a graph based on each data created by the calculation unit 31, each data stored in the data storage unit 32, and the like. The created graph is, for example, a reaction time course indicating the reaction process of the mixed solution.

[Storage unit]
The storage unit 50 stores various types of information. The storage unit 50 stores, for example, sample information, correspondence information, information on a specific sample (hereinafter also referred to as a specific sample), and the like in advance. That is, the storage unit 50 includes at least functions of a sample information storage unit, a subject information storage unit, and a correspondence information storage unit. The storage unit 50 outputs information stored in the storage unit 50 to each unit based on an instruction from the system control unit 70.

  The sample information is information for identifying the sample. Sample information includes, for example, sample ID, patient name, and the like. The sample ID includes, for example, a sample UID assigned to the sample. For example, the identification unit 40 identifies a specific sample based on the sample UID. The sample ID is assigned in advance to all samples measured by the automatic analyzer 10.

  The storage unit 50 stores information on the specific sample in advance before the measurement operation by the automatic analyzer 10 is started. “Before the start of the measurement operation by the automatic analyzer 10” means, for example, before the reading of the sample container identifier attached to the sample container 61 by the sample container identifier reading unit 62 is started.

  The specific sample refers to a sample distinguished from a normal sample. The specific sample is a sample that needs to be notified to the operator or the like during the measurement operation of the automatic analyzer 10. The measurement operation includes, for example, the start of sample measurement, the end of sample measurement, and the like. The specific sample is a sample that needs to be monitored, tracked, etc. by an operator or the like during the measurement operation of the automatic analyzer 10. Examples of such a sample include a sample having a high probability of occurrence of abnormality in the measurement result, a sample for which the measurement result is to be confirmed immediately. These specimens are specific specimens to be distinguished from other specimens. The operator and the like include an operator who operates the automatic analyzer 10 and a person who is near the automatic analyzer 10.

  In this embodiment, the specific sample is identified by an operator of the automatic analyzer 10 or the like. The specific sample is identified by, for example, whether or not the specific sample has specific information. The specific information is information for identifying a specific specimen. The specific information is, for example, information that can cause an abnormal measurement in the measurement by the analysis unit 24 (for example, the photometry unit 12). Specific information includes, for example, personal information of a subject corresponding to a specific specimen. The personal information of the subject includes, for example, age, information on a specific past illness, specific affliction information, specific medication information, and the like.

  Moreover, the memory | storage part 50 can memorize | store the test | inspection information newly acquired by the automatic analyzer 10 or other analyzers. The specific information can also be set as appropriate from information included in the inspection information.

  The operator or the like refers to the sample information corresponding to the sample stored in the storage unit 50 or the like, and determines whether or not the sample information includes preset specific information. When the specific information is included in the sample information, the operator determines that the sample is the specific sample. An operator or the like inputs a sample ID for identifying a sample determined to be a specific sample from the operation unit 80 or the like. The sample ID is input by an operator or the like before the measurement operation of the automatic analyzer 10 is started. The input of the sample ID is performed, for example, on the day before the day when the sample is measured by the automatic analyzer 10. The input of the sample ID is performed at once for each scheduled measurement date of the sample, for example. The sample ID can be input by a person other than the operator of the automatic analyzer 10, for example. The person other than the operator of the automatic analyzer 10 is, for example, an inspection engineer or a doctor. For example, a laboratory technician refers to sample information corresponding to a sample measured by the automatic analyzer 10 using an external terminal (not shown). The laboratory technician specifies a sample corresponding to the specific sample based on the sample information. The laboratory technician further inputs a sample ID for identifying the sample specified as the specific sample from the external terminal. The input information is stored in the storage unit 50, a storage unit 200 described later, and the like via a network (not shown).

  When a sample ID for identifying a sample specified as a specific sample by an operator or the like (hereinafter referred to as a sample ID of a specific sample) is input to the automatic analyzer 10 by an operation by the operator or the like, the storage unit 50 The sample ID is stored as information on the specific sample. FIG. 3 is a table showing an example of information on a specific specimen. As shown in FIG. 3, this table shows information on the sample ID of the specific sample input by the operator or the like.

  A storage unit 200 is connected to the automatic analyzer 10. The storage unit 200 is, for example, an information system in which a lot of medical information is integrated.

  Examples of the information system include a laboratory information system (LIS), a hospital information system (HIS), and the like. The LIS stores, for example, patient treatment information, patient medication information, and the like. In the HIS, for example, patient chart information and the like are stored. The specific information can be appropriately set from the information listed above. When the storage unit 200 is connected to the automatic analyzer 10, the storage unit 200 can substitute for the function of the storage unit 50.

  The correspondence information includes, for example, correspondence information between the specimen and the sample container, correspondence information between the reaction container and the placement position, and the like. The correspondence information between the sample and the sample container is configured, for example, by associating the sample container ID of the sample container 61 in which the sample is accommodated with the sample ID of the sample. FIG. 4 is a table showing an example of correspondence information between specimens and sample containers.

  As shown in FIG. 4, this table shows the correspondence between the sample ID and the sample container ID. A sample container 61 corresponding to the sample container ID contains a sample corresponding to the sample ID. Thereby, the correspondence relationship between the sample container 61 and the specimen stored in the sample container 61 can be known. The correspondence information between the specimen and the sample container is stored in the storage unit 50 in advance.

  FIG. 5 is a table showing an example of correspondence information between a specific specimen and a sample container. For example, before the measurement by the automatic analyzer 10, the storage unit 50 stores correspondence information between a specific sample and a sample container as shown in FIG. This correspondence information is information indicating the correspondence between the information on the specific sample and the information on the sample container in which the specific sample is stored. With this correspondence information, the sample container in which the specific sample is accommodated can be specified. The correspondence information is created by the association unit 43 described later based on the information on the specific sample and the correspondence information between the sample and the sample container after the information on the specific sample is input.

  FIG. 6 is a table showing an example of correspondence information between reaction containers and placement positions. This table shows correspondence information between the information on the reaction vessel 51 and the position of the reaction vessel 51 in the mounting portion 5a. As shown in FIG. 6, this table shows the correspondence between the reaction container ID and the placement position number in the reaction container 5.

  The correspondence information between the reaction container and the placement position is position information in the reaction chamber 5 of the reaction container 51. For example, numbers (1 to n) are sequentially attached to the placement portion 5a of the reaction vessel 51 in the reaction chamber 5 with a specific position as a reference (for example, 0). The correspondence information between the reaction container and the placement position is correspondence information in which the number assigned to the placement portion 5a is associated with the reaction container ID of the reaction container 51. The reaction vessel 51 is placed on the placement unit 5a based on the correspondence information between the reaction vessel and the placement position.

[Identifier]
The identification unit 40 includes a reading unit 41, an identification processing unit 42, and an association unit 43. The identification unit 40 identifies the subject corresponding to the sample dispensed into the reaction container.

(Reading section)
The reading unit 41 reads the identifier and transmits the read information to the identification processing unit 42. The identifier is read without contact, for example. The reading unit 41 includes the sample container identifier reading unit 62 and the reaction container identifier reading unit 52 described above.

  The reading unit 41 includes, for example, a light irradiation device (not shown). The light irradiation device receives the reflected light from the identifier by irradiating the identifier with infrared light or visible light. The received reflected light information is output to the identification processing unit 42.

  Further, the reading unit 41 includes, for example, a photographing device (not shown). The imaging device captures the identifier to obtain image information. This photographing information is transmitted to the identification processing unit 42.

  When the reading unit 41 has a configuration of a light irradiation device or a photographing device, for example, a barcode can be used as the identifier. In this case, the reading unit 41 includes a barcode reader having the above configuration. In addition, the barcode as an identifier at this time may be a one-dimensional barcode or a two-dimensional barcode.

  The reading unit 41 includes, for example, a reading device (not shown). The reading device reads the identifier information in a non-contact manner to obtain identification information. This identification information is transmitted to the identification processing unit 42. When the reading unit 41 has the configuration of a reading device, the identifier includes, for example, an IC chip that can exchange information with the reading unit 41 in a non-contact manner. The IC chip transmits a carrier from the reading unit 41 and supplies power to the IC chip by electromagnetic induction. Furthermore, communication is performed between the reading unit 41 and the IC chip by carrier modulation.

[Identification processor]
The identification processing unit 42 obtains identifier information by processing the read information received from the reading unit 41. The identification processing unit 42 further outputs information on this identifier to the detection unit 60. For example, the identification processing unit 42 acquires the sample container ID from the information on the sample container identifier acquired by the sample container identifier reading unit 62, and outputs the sample container ID to the detection unit 60.

  Further, the identification processing unit 42 acquires sample information corresponding to this identifier from the acquired identifier information. The identification processing unit 42 further outputs this sample information to the detection unit 60. For example, the identification processing unit 42 is accommodated in the sample container corresponding to the sample container ID based on the sample container ID acquired from the sample container identifier and the correspondence information between the specimen and the sample container shown in FIG. Obtain the specimen ID of the specimen. The identification processing unit 42 outputs the acquired sample ID to the detection unit 60.

  When the reading unit 41 is, for example, a light irradiation device, the identification processing unit 42 obtains identifier information by analyzing the received reflected light information.

  In addition, when the reading unit 41 is, for example, a photographing device, the identification processing unit 42 obtains identifier information by analyzing the received image information.

[Association part]
When the measurement operation by the analysis unit 24 is started and the sample is dispensed into the reaction container 51, the associating unit 43 stores the identification information of the reaction container 51 and the sample that stores the sample dispensed into the reaction container 51. The identification information of the container 61 is associated. Specifically, the associating unit 43 associates the reaction container ID of the reaction container 51 into which the specimen has been dispensed with the sample container ID of the sample container 61 in which the dispensed specimen is stored. The associating unit 43 further acquires a sample ID corresponding to the sample container ID from the identification processing unit 42 and creates correspondence information between the sample and the reaction container 51.

[Detection unit]
The detection unit 60 detects the specific sample from the sample to be measured in the analysis unit 24 based on the sample ID of the specific sample stored in the storage unit 50 in advance. As an example of this detection, a case where a sample ID is received from the identification processing unit 42 and a specific sample is detected based on this sample ID is shown below.

  The detection unit 60 receives the sample ID received from the identification processing unit 42 and collates this sample ID with the sample ID of a specific sample stored in advance in the storage unit 50.

  As a result of this collation, when the sample ID received from the identification processing unit 42 matches the sample ID of the specific sample, the detection unit 60 determines that the sample corresponding to the sample ID is the specific sample. The detection unit 60 further specifies the sample container 61 in which the sample determined as the specific sample from the correspondence information between the sample and the sample container is stored.

  As another example of the detection, a case where a sample container ID is received from the identification processing unit 42 and a specific sample is detected based on the sample ID will be described below.

  Upon receiving the sample container ID from the identification processing unit 42, the detection unit 60 acquires a sample ID corresponding to the sample container ID based on the correspondence information between the sample and the sample container stored in the storage unit 50.

  The detection unit 60 collates the acquired sample ID with the sample ID of the specific sample stored in the storage unit 50 in advance.

  As a result of this collation, when the acquired sample ID matches the sample ID of the specific sample, the detection unit 60 determines that the sample corresponding to the acquired sample ID is the specific sample.

  When the specific sample is detected by the detection unit 60, the detection unit 60 outputs, for example, the detection information to the output unit 90 together with the related information of the specific sample. For example, the detection unit 60 may store the detection information in the storage unit 50 together with the related information of the specific specimen. The related information of the specific sample is information on the patient corresponding to the specific sample. As this information, patient ID, a patient name, etc. are mentioned, for example. This information is displayed, for example, on a display screen provided in the display unit 91 during measurement of the detected specific specimen.

[System controller]
The system control unit 70 controls the analysis control unit 25, the data processing unit 30, the identification unit 40, the detection unit 60, and the output unit 90 in an integrated manner. The operation unit 80 inputs various command signals to the system control unit 70.

[Operation section]
Examples of the operation unit 80 include those having an independent operation input function such as a mouse and a keyboard. In addition, an operation input function such as a touch panel and a display function may be combined.

  The operation input made by the operation unit 80 is input as a command to the system control unit 70, for example. This operation input may be input directly from an operation device constituting the operation unit 80, or indirectly such as selecting an object such as a button displayed on the display unit 91 with a mouse or the like. It may be input.

[Output section]
The output unit 90 includes a display unit 91, a printing unit 92, and a notification unit 93. The output unit 90 outputs information received from the data processing unit 30, the operation unit 80, the detection unit 60, and the like to the outside based on the control of the system control unit 70. This output includes display output by the display unit 91, print output by the printing unit 92, notification output by the notification unit 93, and the like.

[Operation of automatic analyzer]
Next, the operation of the automatic analyzer 10 will be described. FIG. 7 is a flowchart showing an example of the operation of the automatic analyzer 10. In this description, FIGS. 1 to 6 and FIGS.

  The automatic analyzer 10 operates to notify the start of the measurement to the outside when the absorbance measurement of the sample corresponding to the specific sample registered in the storage unit 50 is started. Further, when the measurement of the specific specimen is finished, the operation is performed so as to notify the outside that the measurement has been finished. Further, after the measurement of the specific sample is completed, the measurement result is displayed on the display screen.

  First, the operator of the automatic analyzer 10 prepares for a sample to be measured by the automatic analyzer 10 (step S001). In the preparation before the measurement, the operator specifies a sample corresponding to the specific sample from the samples to be measured (step S002). The specific sample is identified by whether or not the specific information is included in the sample information corresponding to the sample.

  The operator inputs the sample ID of the sample specified as the specific sample to the automatic analyzer 10 (step S003). The input sample ID is stored in the storage unit 50 as the sample ID of the specific sample. The operator creates specific sample information as shown in FIG. 3, for example, by sequentially storing the sample IDs of the specific samples in the storage unit 50 (step S004).

  Next, the measurement of the sample by the automatic analyzer 10 is started (step S005). When the measurement of the sample is started, the detection unit 60 detects the specific sample from the information of the sample container 61 that stores the sample used for the measurement (step S006). The detection of the specific specimen by the detection unit 60 is performed as follows, for example.

  When the automatic analyzer 10 starts the measurement operation, the rack sampler 65 operates so as to transport the plurality of racks 63 to a specified suction position of the sample dispensing probe 7. A plurality of sample containers 61 each storing a sample are placed on the rack 63.

  Each of the plurality of sample containers 61 is labeled with a sample container identifier. A sample container barcode including information on the sample container ID is displayed on the label. The barcode reader as the sample container identifier reading unit 62 reads the sample container barcode and outputs the read information to the identification processing unit 42. The identification processing unit 42 receives this read information and acquires a sample container ID that is information for identifying the sample container 61. Examples of the method for identifying the sample container 61 include the following methods.

  As a first example of the method of identifying the sample container 61, there is a method of reading the identifier of the sample container 61 at a specified suction position of the sample dispensing probe 7 and identifying the sample container 61 based on the read information. The sample container 61 is transported to a specified suction position of the sample dispensing probe 7 by the rack sampler 65. The bar code reader is configured to be able to read the sample container bar code at the prescribed suction position. For example, the barcode reader is provided at a position where the sample container barcode can be read at the prescribed suction position.

  When the sample container 61 is transported to the prescribed suction position, the barcode reader reads the sample container barcode attached to the sample container 61 and acquires the sample container barcode read information. The reading of the sample container bar code by the bar code reader may be performed at any timing as long as the sample container 61 is at the specified suction position of the sample dispensing probe 7. The barcode reader can read the sample container barcode before the sample in the sample container 61 is aspirated by the sample dispensing probe 7, for example. The bar code reader outputs the acquired sample container bar code reading information to the identification processing unit 42.

  The identification processing unit 42 receives the sample container barcode reading information, acquires the sample container ID from the sample container barcode reading information, and outputs this to the detecting unit 60. The detection unit 60 receives the sample container ID, and acquires the sample ID based on the correspondence information between the sample and the sample container stored in advance in the storage unit 50. As correspondence information between the specimen and the sample container, for example, the information shown in FIG. 4 is used.

  The detection unit 60 further collates the information on the specific sample stored in the storage unit 50 with the acquired sample ID. Specifically, the sample ID of the specific sample registered in the information of the specific sample is collated with the sample ID of the acquired sample. As a result of this collation, if there is a sample that matches the sample ID of the specific sample registered in the specific sample information, the sample is detected as the specific sample.

  Further, as a second example of the method for identifying the sample container 61, there is a method in which the position information of the sample container 61 in the rack sampler 65 is stored in the storage unit 50 in advance. From this position information, the sample container 61 in which the sample has been aspirated by the sample dispensing probe 7 can be specified. This is performed by specifying the position of each sample container 61 in the rack 63 after specifying the position of each rack 63 in the rack sampler 65.

  The rack 63 is provided with a label as an identifier, and a rack bar code including rack ID information is displayed on the label. The rack barcode is read by a barcode reader which is a rack identifier reading unit (not shown). The read information is stored in the storage unit 50 in association with the position information of the rack 63 in the rack sampler 65. Thereby, the position of each rack 63 in the rack sampler 65 can be specified.

  The sample container barcode is read by a barcode reader which is the sample container identifier reading unit 62. The read information is stored in the storage unit 50 in association with the position information of the sample container 61 in the rack 63. Thereby, the position of each sample container 61 in the rack 63 is specified. The barcode reader may be provided at any location as long as it is provided at a location where the sample vessel barcode displayed on the label attached to the sample vessel 61 can be read.

  Through the processing described above, the position of the sample container 61 in the rack sampler 65 is specified, and correspondence information in which the sample container ID is associated with the position information is stored in the storage unit 50. Based on this correspondence information and the control information of the analysis control unit 25, for example, the identification unit 40 can specify the sample container 61 in which the sample is aspirated by the sample dispensing probe 7. Further, based on the sample container ID of the specified sample container 61, the detection unit 60 detects the specific specimen in the same manner as described above.

  Next, a sample is dispensed from the sample container 61 to the reaction container 51 (step S007). This dispensing is performed by the sample dispensing probe 7.

  At this time, the detection unit 60 determines whether the sample dispensed in the reaction container 51 corresponds to the specific sample (step S008). A determination unit (not shown) provided in the detection unit 60 determines whether or not the sample stored in the sample container 61 that is a dispensing source is a specific sample. The detection unit 60 performs this determination based on correspondence information between the specific specimen and the sample container shown in FIG.

  When the detection unit 60 determines that the sample dispensed into the reaction container 51 corresponds to the specific sample (step S008: YES), the detection unit 60 outputs information on this determination to the association unit 43. Upon receiving this determination information, the associating unit 43 associates the sample ID corresponding to the specific sample with the dispensed reaction container ID (step S009). This correspondence information is stored in the storage unit 50. This correspondence information is created by the associating unit 43 each time a specific sample is dispensed into the reaction container 51 and is also output to the storage unit 50. As a result, a table showing correspondence information between the specific specimen and the reaction container as shown in FIG. In the table showing the correspondence information between the specific specimen and the reaction container, the reaction container ID for identifying the reaction container 51 and the specimen ID for identifying the specimen that is the specific specimen are associated with each other.

  On the other hand, when the detection unit 60 determines that the sample dispensed into the reaction container 51 does not correspond to the specific sample detected by the detection unit 60 (step S008: NO), that is, in the case of a normal sample, The normal measurement process is performed without performing the corresponding process (step S010). A normal measurement process is performed as follows, for example. The reagent dispensing probe prepares a mixed solution by further dispensing a reagent to a normal sample stored in the reaction vessel 51 and reacting it. The photometric unit 12 measures the components of the mixed solution and outputs the measurement result to the output unit 90. When this output is performed, the automatic analyzer 10 ends the measurement operation on the sample.

  The determination process in step S008 is performed corresponding to the identification process of the sample container 61 in step S006.

  In step S006, for example, when identifying the sample container 61 based on the first example of the method for identifying the sample container 61 described above, the detection unit 60 performs the process of step S008 subsequent to the process of step S006. This is because in this example, the reading of the sample container bar code and the dispensing by the sample dispensing probe 7 are performed almost simultaneously.

  In step S006, for example, when the sample container 61 is identified based on the above-described second example of the method for identifying the sample container 61, the detection unit 60 first obtains the position information of the sample container stored in the storage unit 50. The sample container 61 is specified with reference. Next, the detection unit 60 performs the processing in step S008 after specifying the specimen stored in the sample container 61. In this example, when the order of the sample containers 61 to be dispensed by the sample dispensing probe 7 is known, the timing for performing the process of step S008 can be set in advance.

  Moreover, in the process of step S008, it is necessary to specify the reaction container 51 into which the specific specimen is dispensed. The reaction vessel 51 can be specified by, for example, the following process.

  As a first specific example of the reaction vessel 51, when a sample is dispensed into the reaction vessel 51 by the sample dispensing probe 7, the reaction vessel 51 into which this sample has been dispensed is identified.

  The reaction container identifier reading unit 52 reads the reaction container identifier attached to the reaction container 51 when the sample is dispensed into the reaction container 51 by the sample dispensing probe 7. The reaction container identifier reading unit 52 outputs the read information to the identification processing unit 42. Upon receipt of the read information, the identification processing unit 42 acquires the reaction container ID corresponding to the upper part of the reading, and stores it in the storage unit 50. Output. The storage unit 50 stores the reaction container ID. In this case, the reaction vessel identifier is, for example, a reaction vessel barcode. The reaction container identifier reading unit 52 is, for example, a barcode reader.

  As a specific second example of the reaction container 51, in the preparation before the measurement of the sample by the automatic analyzer 10, the correspondence information between the reaction container and the mounting position is created in advance.

  The correspondence information between the reaction container and the placement position is created as follows, for example. First, the reaction vessel identifier reading unit 52 reads the reaction vessel identifier attached to the reaction vessel 51 placed on the placement unit 5a. The reaction vessel identifier reading unit 52 reads the reaction vessel identifier attached to the reaction vessel 51 placed at an arbitrary position, and then attaches the reaction vessel attached to the reaction vessel 51 adjacent in the direction in which the reaction vessel 5 rotates. Read the identifier. The reaction vessel identifiers read by the reaction vessel identifier reading unit 52 are sequentially performed in the direction in which the reaction chamber 5 rotates, and are finally performed for all the reaction vessels 51 placed on the placement unit 5a. Next, a placement position number assigning unit (not shown) assigns placement position numbers in the order in which the reaction container identifiers are read. By this processing, correspondence information between the reaction container and the placement position as shown in FIG. 6 is generated. Based on the generated correspondence information, the detection unit 60 can determine at which position of the placement unit 5a the desired reaction vessel 51 is located. Thereby, the detection unit 60 can track the movement of the reaction vessel 51 from the control information by the analysis control unit 25.

  As a specific third example of the reaction container 51 to be dispensed, correspondence between a predetermined placement position and a placement position number of the placement portion 5a is set in advance in preparation for measurement of a sample by the automatic analyzer 10. In addition, the placement position correspondence information may be stored in the storage unit 50. In this case, in step S009, the placement position correspondence information corresponds to the specimen ID of the specimen stored in the sample container 61 as the dispensing source and the placement position number where the reaction container 51 as the dispensing destination is placed. It becomes the attached information. Thereby, the detection unit 60 can track the movement of the reaction vessel 51 placed at the position corresponding to the placement position number from the control information by the analysis control unit 25. Further, in this case, since the detection unit 60 does not use the reaction container ID for tracking the movement of the reaction container 51, it is not necessary to provide the reaction container identifier reading unit 52.

  As described above, the detection unit 60 tracks the specific sample by specifying the sample container 61 in which the specific sample is stored and specifying the reaction container 51 in which the specific sample is dispensed from the sample container 61.

  A liquid mixture is prepared by dispensing reagents such as the first reagent and the second reagent into the reaction container 51 containing the specific specimen (step S011). This reagent dispensing is performed by the first reagent dispensing probe 8 and / or the second reagent dispensing probe 9.

  Next, the photometric unit 12 starts measuring the absorbance of the liquid mixture containing the specific specimen (step S012). At this time, the detection unit 60 detects that the absorbance measurement of the liquid mixture containing the specific specimen has been started, and outputs information on this detection to the system control unit 70. Upon receiving this detection information, the system control unit 70 controls the notification unit 93. The notification unit 93 that has received control from the system control unit 70 notifies the outside of the start of absorbance measurement of the liquid mixture containing the specific sample (step S013). This detection can be performed, for example, from the correspondence information between the specific specimen and the reaction container shown in FIG. 8 and the control information of the reaction container 51 by the system control unit 70.

  In this case, the alerting | reporting part 93 alert | reports the measurement start of a specific sample outside, for example by sounding a buzzer. In this case, the system control unit 70 controls the display unit 91. The display unit 91 that has received control from the system control unit 70 displays the sample information of the specific sample contained in the mixed liquid whose measurement has been started on the display screen (step S014). The sample information of the specific sample is, for example, the patient ID, patient name, sex, age, etc. of the patient corresponding to this sample. Thereby, the operator of the automatic analyzer 10 can know information such as a patient corresponding to the specific sample for which measurement has been started.

  FIG. 9 shows an example of a display screen 510 on which sample information of a specific sample for which absorbance measurement has been started is displayed. As shown in FIG. 9, the display screen 510 shows the measurement start time and the sample information of the specific sample for which the measurement is started as the specific sample measurement start measurement information. The sample information of the specific sample can be appropriately selected from those described later as information on the subject corresponding to the specific sample. Sample information of a specific sample includes, for example, sample ID, patient name, sex, age, etc., clinical department, ward, and the like.

  In step S013, the detection unit 60 detects that the absorbance measurement of the mixed liquid containing the specific sample has started, for example, as shown in the following example.

  As a first example, based on the first specific example of the reaction container 51 described above, the reaction container 51 into which a specific sample has been dispensed is specified. Specifically, the detection unit 60 collates the reaction container ID corresponding to the reaction container in which the specific sample is accommodated with the reaction container ID corresponding to the reaction container 51 in which the absorbance measurement is started for the accommodated sample. When the reaction container IDs match in this verification, the detection unit 60 detects that the measurement of the specific sample has started. In this case, another reaction container identifier reading unit (not shown) is provided in the vicinity of the photometric unit 12 in order to identify the reaction container 51 in which the absorbance measurement is started for the contained sample.

  As a second example, the reaction container 51 into which a specific sample is dispensed is specified based on the above-described second specific example of the reaction container 51. Specifically, the detection unit 60 is a reaction container into which a specific sample has been dispensed based on the correspondence information between the reaction container and the mounting position shown in FIG. 6 and the control information of the reaction container 51 by the analysis control unit 25. 51 positions can be detected. In addition, the position in the reaction chamber 5 of the reaction vessel 51 where the absorbance measurement is started by the photometric unit 12 for the contained specimen is known. Then, the detection unit 60 can identify the reaction container 51 stopped at the photometric position based on the correspondence information between the reaction container and the placement position and the control information of the reaction container 51 by the analysis control unit 25.

  As a third example, the reaction container 51 into which a specific sample has been dispensed is specified based on the above-described third specific example of the reaction container 51. Specifically, the detection unit 60 detects the position of the reaction container 51 into which the specific sample has been dispensed based on the placement position number and the control information of the reaction container 51 by the analysis control unit 25. In addition, the position in the reaction chamber 5 of the reaction vessel 51 where the absorbance measurement is started by the photometric unit 12 for the contained specimen is known. Then, the detection unit 60 acquires the mounting position number of the mounting unit 5a stopped at the photometric position based on the control information of the reaction vessel 51 by the analysis control unit 25. Thereby, the reaction vessel 51 stopped at the photometric position can be specified.

  In the first example and the second example described above, correspondence information between the specific sample and the reaction container in which the sample ID of the specific sample and the reaction container ID are associated as shown in FIG. 8 is created. Further, in the third example, correspondence information between the specific sample and the reaction container in which the sample ID of the specific sample and the placement position number of the reaction container 51 are associated is created.

  When the photometric unit 12 finishes measuring the absorbance of the mixed solution containing the specific sample (step S015), the detection unit 60 detects that the absorbance measurement of the mixed solution containing the specific sample is completed. The detection unit 60 outputs the detection information to the system control unit 70. The system control unit 70 controls the notification unit 93. The notification unit 93 that has received control from the system control unit 70 notifies the outside that the absorbance measurement of the liquid mixture containing the specific sample has been completed (step S016). In this case, the alerting | reporting part 93 alert | reports the completion | finish of a measurement of a specific sample outside, for example by sounding a buzzer.

  Further, the display unit 91 that receives control from the system control unit 70 displays the measurement result of the specific sample for which measurement has been completed on the display screen (step S017). The measurement result of the specific sample is displayed on the display screen separately from the measurement result of the normal sample. When the measurement result of the specific sample and the measurement result of the normal sample are displayed on the same display screen, for example, they are displayed in different windows. Further, when there are a plurality of display screens of the display unit 91, the measurement result of the specific sample and the measurement result of the normal sample are displayed on different display units 91, respectively. At this time, the information displayed on the display screen of the display unit 91 may include sample information of the detected specific sample.

  The timing for displaying the measurement result of the specific sample on the display screen is, for example, after the measurement of a plurality of samples including the specific sample is completed. At this timing, the system control unit 70 controls the display unit 91 to collectively display the measurement results of the detected specific samples on the display screen. In addition, this timing includes, for example, when the measurement of the specific sample is completed when a plurality of samples including the specific sample are sequentially measured. At this timing, the system control unit 70 controls the display unit 91 to sequentially display the measurement results of the specific sample for which measurement has been completed on the display screen.

  FIG. 10 is a diagram showing an example of the display screen 210 on which the measurement result of the specific sample is displayed. The display screen 210 displays the measurement result of the specific sample after the measurement of the specific sample is completed. On the display screen 210, the measurement result of the specific sample, the measurement result of the absorbance measurement of the specific sample, the graph 211 indicating the reaction time course which is the time series change of the absorbance, the list 212 of the measurement items for which the measurement has been completed, and the like are displayed. .

  A graph 211 showing the reaction time course shows a reaction curve showing a time-series change in concentration of the substance to be measured. The graph 211 indicating the reaction time course is created by a graph creation unit (not shown) provided in the data processing unit 30. The graph creation unit creates reaction time course graph data based on the measurement result output from the analysis unit 24.

  In addition, by selecting a desired measurement item, the measurement item list 212 is displayed by switching a measurement result, a graph 211 indicating a reaction time course, and the like in the measurement item. For example, the operator selects a desired measurement item by clicking a portion where the desired measurement item is displayed on the display screen of the display unit 91 with a mouse or the like.

  FIG. 10 shows the measurement result of the measurement item A of the specific sample. In the measurement item list 212, the measurement items to be noted are highlighted. Thereby, the operator can easily grasp the measurement items to be noted in the specific sample. This highlighting is shown separately from other items by, for example, adding a specific color to a portion where the specific item is displayed in the measurement item list 212.

  FIG. 11 is a flowchart showing another example of the operation of the automatic analyzer 10. The automatic analyzer 10 operates to notify the start of the measurement to the outside when the absorbance measurement of the sample corresponding to the specific sample registered in the storage unit 50 is started. Further, when the measurement of the specific specimen is finished, the operation is performed so as to notify the outside that the measurement has been finished. Further, after the measurement of the specific sample is started, the measurement result can be displayed in real time on the display unit, and the measurement result is displayed on the display unit after the measurement of the specific sample is completed.

  The processing from step S020 to S033 in this flowchart is the same as the processing from step S001 to S014 in the flowchart shown in FIG. By this processing, the operator grasps that the absorbance measurement of the specific specimen has been started.

  When the absorbance measurement of the specific sample is started and the display of the measurement status is requested during the measurement of the absorbance measurement (step S034: YES), the system control unit 70 controls the display unit 91. The display unit 91 controlled by the system control unit 70 displays information including the measurement status of the absorbance measurement for the specific sample on the display screen (step S035). At this time, the information displayed on the display unit 91 may include sample information of the specific sample. If display of the measurement status is not requested during the measurement of absorbance, the process proceeds to step S036 (step S034: NO, step S036).

  In step S034, the measurement status display request is made as follows, for example. When the absorbance measurement of the specific sample is started, the sample information of the specific sample for which the absorbance measurement is started is displayed on the display screen of the display unit 91 by the processing in steps S020 to S033. The sample information of the specific sample is provided with a link for displaying details of the measurement status. The operator can request display of the measurement status by selecting this link with a mouse or the like.

  FIG. 12 is a diagram showing an example of a display screen 310 showing the measurement status of a specific sample. When the absorbance of a specific sample is measured, the display screen 310 displays at least a measurement progress bar 311, a sampling time, a measurement end expected time, a measurement item list 312, and a graph 313 indicating a reaction time course. Is done.

  The sampling time is a time during which the photometric unit 12 performs absorbance measurement for this specific specimen. The number of absorbance measurements and the absorbance measurement time interval in the photometric unit 12 are set in advance according to the specimen, measurement items, and the like. This setting is stored in the storage unit 50, for example.

  The expected measurement end time is calculated by a measurement end time calculation means (not shown). The measurement end time calculating means takes a difference between a preset number of absorbance measurements and the number of absorbance measurements that have been completed at the present time. Next, the measurement end time calculation means calculates the remaining time by multiplying this difference by the time interval of absorbance measurement. Next, the measurement end time calculating means calculates the expected measurement end time from the remaining time and the current time.

  A measurement progress bar 311 indicates the progress of measurement of the specific sample being tracked. The measurement progress bar 311 has a movable part 311a. The movable portion 311a is configured to be movable from the left end to the right end of the measurement progress bar 311. The position of the movable part 311a in the measurement progress bar 311 indicates how much the measurement of the automatic analyzer 10 for the specific sample has progressed. This position corresponds to the number of times of sampling by the photometric unit 12, for example.

  For example, when the movable portion 311a is at the left end of the measurement progress bar 311, it indicates that sampling by the photometric unit 12 has been performed once. The movable portion 311a moves to the right on the measurement progress bar 311 every time sampling is performed by the photometry unit 12. When the number of times of sampling by the photometry unit 12 reaches the specified number of times of sampling, the movable portion 311a is positioned at the right end of the measurement progress bar 311. Thus, the progress of absorbance measurement by the photometric unit 12 can be known from the position of the movable part 311a on the measurement progress bar 311.

  The measurement item list 312 and the graph 313 indicating the reaction time course have the same configuration as the measurement item list 212 and the reaction time course graph 211 described above with reference to FIG. The graph 313 is created by a graph creation unit (not shown). The graph creation unit acquires the measurement result output from the analysis unit 24 in real time. The graph creation unit creates and processes the graph data of the reaction time course in real time based on the acquired measurement result. In addition, when a graph 313 indicating the reaction time course is displayed on the display screen, when a new measurement result is output from the analysis unit 24, the graph creation unit generates a reaction time course based on the new measurement result. The graph data can be updated.

  When the photometric unit 12 finishes measuring the absorbance of the mixed solution containing the specific sample (step S036), the detection unit 60 detects that the absorbance measurement of the mixed solution containing the specific sample has been completed. The detection unit 60 outputs the detection information to the system control unit 70. Upon receiving this detection information, the system control unit 70 controls the notification unit 93. The notification unit 93 controlled by the system control unit 70 notifies the outside that the absorbance measurement of the liquid mixture containing the specific sample has been completed (step S037).

  Further, the system control unit 70 that has received the detection information controls the display unit 91. The display unit 91 controlled by the system control unit 70 displays the measurement result of the specific sample contained in the mixed liquid whose measurement has been completed on the display screen (step S038). The display unit 91 displays, for example, a measurement result similar to that shown in FIG. 10 on the display screen.

  Next, an example of the automatic analyzer 10 of this embodiment will be described. This embodiment corresponds to the flowchart shown in FIG.

  Patient A is admitted to the surgical ward due to a fracture. Patient A has chronic illness and is prescribed a medicine (drug) from a hospital different from the hospital where he is hospitalized.

  When this drug enters the blood, the measurement result by the automatic analyzer may become abnormal. For example, in the measurement item A of the blood test by the automatic analyzer, the value of the measurement result tends to be higher than a normal value. On the other hand, the value of the measurement result B of the blood test by the automatic analyzer tends to be lower than the normal value. Patient A tells a doctor or the like that he is taking this medicine, and the doctor or the like knows this.

  Patient A was to undergo a blood test in connection with the treatment of the fracture. This blood test is performed by an automatic analyzer. Laboratory technician B who is an expert who is used to operating the automatic analyzer knows that patient A is taking medicine.

  Laboratory technician B has determined that monitoring and tracking of the sample corresponding to patient A is necessary in the measurement by the automatic analyzer. Therefore, the laboratory technician B pre-registers the blood sample D of the patient A as a specific sample in preparation before the measurement by the automatic analyzer of the blood sample.

  Laboratory technician B has displayed an input screen M for tracking sample registration as shown in FIG. 13 on the display screen of the automatic analyzer for measuring the blood sample. The laboratory technician B refers to the input screen M and inputs information on the patient A, information on the blood sample D, and the like from the operation unit. This information is stored in the storage unit as specific specimen information number 021 (corresponding to steps S020 to S023).

  The tracking sample registration input screen M has an input box in which information of “sample ID”, “patient name”, “gender”, “age”, “clinical department”, “ward” and “measurement item” can be input. Have.

  Laboratory technician B enters “sample ID”, “patient name”, “sex”, “age”, “clinic”, “ward” and “measurement item” corresponding to patient A in the input box. Laboratory technician B inputs blood test measurement item A and measurement item B, which require special attention in absorbance measurement, in the “measurement item” input box.

  Laboratory technician C who actually measures blood sample D with an automatic analyzer is a beginner unfamiliar with the operation of the automatic analyzer. Laboratory Technician C is committed to using the automated analyzer correctly. Laboratory technician C knew that he needed to be careful about measuring blood sample D. However, the automatic analyzer measures several hundred samples per day, for example. Therefore, laboratory technician C cannot afford to check blood sample D by checking each sample container one by one.

  A sample container E containing a blood sample D has been carried to a laboratory where an automatic analyzer is installed. However, laboratory technician C does not know that. Information that the blood sample D is stored in the sample container E is stored in the LIS as correspondence information between the sample and the sample container. The sample container E is placed on the rack F. Further, the rack F is placed on a rack sampler which is a transport means of the automatic analyzer.

  The rack F was sent by the rack sampler to the sample dispensing position in the vicinity of the sample dispensing probe provided in the automatic analyzer. The sample dispensing probe started the dispensing operation for the blood sample D accommodated in the sample container E. Thereby, the measurement operation of the automatic analyzer for blood sample D is started (corresponding to step S024).

  A label is affixed to the side surface of the sample container E, and a barcode is printed on the label. This bar code includes information on the sample container ID.

  The rack F stopped once when it moved to the sample dispensing position. In the vicinity of the position where the rack F stops, a barcode reader is provided. The barcode reader is provided at a position where the barcode printed on the label can be read without obstructing the movement of the rack.

  Once the rack F stopped, the barcode reader read the barcode printed on the label affixed to the sample container E.

  The read barcode information includes sample container ID information for identifying the sample container E. The automatic analyzer acquires the sample ID corresponding to the sample stored in the sample container E from the information on the sample container ID and the correspondence information between the sample and the sample container stored in advance in the LIS. This sample ID is a sample ID for identifying the blood sample D.

  The automatic analyzer collates the sample ID for identifying the blood sample D with the sample ID registered as the specific sample.

  The list of sample IDs registered as specific samples includes a sample ID for identifying blood sample D. Thus, the sample ID for identifying the blood sample D stored in the sample container E matches the sample ID registered as the specific sample. Therefore, the automatic analyzer detects blood sample D as a specific sample (corresponding to step S025).

  The sample dispensing probe dispensed blood sample D from sample container E to reaction container G (corresponding to step S026). The automatic analyzer knows that the blood sample D is a specific sample (corresponding to YES at step S027). The automatic analyzer associates the specimen ID for identifying the blood specimen D with the reaction container ID for identifying the reaction container G. The automatic analyzer identifies the reaction container ID from the placement position information of the reaction container G and the correspondence information between the reaction container and the placement position stored in advance in the LIS, and this reaction container ID and blood sample The sample ID for identifying D is associated (corresponding to step S028).

  By adding the first reagent and the second reagent to the reaction container G, a mixed solution containing the blood sample D was prepared (corresponding to step S030).

  The reaction vessel G provided in the automatic analyzer was rotated to move the reaction container G to the photometric position, and absorbance measurement was started by the photometric unit provided in the automatic analyzer (corresponding to step S031). At this time, the automatic analyzer detected that the measurement of the liquid mixture containing the specific sample was started. Simultaneously with this detection, the automatic analyzer sounded a buzzer to notify the outside that the absorbance measurement of the specific specimen has started (corresponding to step S032).

  Laboratory technician C hears this buzzer and recognizes that the absorbance measurement of a specific sample has started. On the display screen, the name of the patient A, the patient ID of the patient A, the medication information of the patient A, and the like, which are the sample information of the blood sample D, are displayed (corresponding to step S033). Therefore, laboratory technician C has recognized that blood sample D of patient A is being measured for absorbance. In addition, on this display screen, a link to a screen indicating the measurement status of blood sample D is displayed. Laboratory technician C selects this link (corresponding to step S034) and displays a screen showing the measurement status of blood sample D (corresponding to step S035), but the measurement has not progressed, so useful information cannot be obtained. It was.

  Laboratory technician C waits until the measurement of blood sample D proceeds to some extent, and again displays information indicating the measurement status of blood sample D on the display screen. The inspection engineer C further selects the measurement item A that is highlighted from among the twelve items shown in the measurement item list displayed on the display screen. By this selection operation, the reaction time course corresponding to the measurement item A was displayed on the display screen. The display screen is a touch panel. Therefore, when a part of the display screen where the measurement item A is displayed is touched, the time course corresponding to the measurement item A is displayed on the display screen. The time course corresponding to the measurement item A displayed on the display screen showed a time-series change in absorbance after the addition of the first reagent and before the addition of the second reagent. The time-series change in the absorbance of the substance contained in the blood sample D shown in the time course of the measurement item A indicates that the reaction after the addition of the first reagent is staggered.

  Examining engineer C further waits for a predetermined time, and then selects measurement item B that is similarly highlighted, and displays the reaction time course corresponding to measurement item B on the display screen. Since measurement item B was in the middle of measurement, the display screen displayed halfway through the reaction time course. The initial value of the absorbance of the substance contained in the blood sample D shown in the time course of the measurement item B was generally lower than the initial value of the normal value. From this information, laboratory technician C thought that patient A had taken the drug before blood collection, but withheld the judgment based on this idea until the end of measurement of blood sample D by the automatic analyzer.

  In response to the completion of the measurement for all the measurement items of blood sample D, the automatic analyzer detects the end of measurement of blood sample D (corresponding to step S036). Subsequently, the automatic analyzer sounded a buzzer indicating the end of the measurement of the specific sample (corresponding to step S037). Furthermore, the automatic analyzer displayed information indicating the measurement result on the display screen (corresponding to step S038).

  Laboratory technician C confirmed the time course corresponding to all the measurement items related to blood sample D from the information of the measurement results displayed on the display screen. At this time, the measurement result of blood sample D has not been transmitted to an external server (LIS, HIS, etc.).

  Of the 12 measurement items included in the measurement result information displayed on the display screen, the result of 10 items excluding the measurement item A and the measurement item B did not have an error flag. From this, the examination engineer C determined that there is no particular problem with the measurement results of these 10 items.

  On the other hand, in the reaction time course corresponding to the measurement result of the measurement item A, the fluctuation of the absorbance value described above is not stable even after the addition of the second reagent, and the final measurement result value is higher than the normal value. It was. The value of this final measurement result is not a correct response. Therefore, laboratory technician C cannot report this measurement result as the measurement result of measurement item A of blood sample D.

  In addition, the reaction time course corresponding to the measurement result of the measurement item B seemed to pass through a normal reaction process at first glance, but the absorbance value as a whole tended to be lower than the normal value. From this information, the laboratory technician C determined that the measurement results were affected by the drug in the measurement item A and the measurement item B.

  For this reason, the inspection engineer C has determined that the measurement results acquired in the above 10 items are reported as they are. In addition, the laboratory technician C determines that the measurement result acquired in the measurement item A is not reported as unmeasurable, but the drug influence flag is added to the unmeasurable information and reported. In addition, the laboratory technician C decides to report the measurement result acquired in the measurement item B as a reference value by adding a flag indicating that there is a drug effect.

  Laboratory technician C made the above-mentioned report by transmitting the measurement results of all the measurement items of blood sample D to the server. These measurement results can be displayed on a display screen of a terminal used by a doctor or the like. These measurement results can also be printed. These measurement results are also transmitted to an external computer. With these things, doctors and the like can grasp the cause from the added flag or the like even if the measurement result by the automatic analyzer shows an abnormality.

[Operation and effect of automatic analyzer]
The automatic analyzer 10 of this embodiment notifies the start of the measurement to the outside when the absorbance measurement for the preset specific sample is started, and when the absorbance measurement for the specific sample is completed, the end of the measurement is externally indicated. To inform. Further, the display unit 91 displays the absorbance measurement process in real time on the display screen after the start of the absorbance measurement for the specific specimen. Further, the display unit 91 displays the final result of the absorbance measurement on the display screen after the measurement of the specific sample is completed. Since the automatic analyzer 10 has such a configuration, it is possible to easily monitor the state of absorbance measurement for a specific sample performed by the photometric unit 12.

  Moreover, since the automatic analyzer 10 of this embodiment notifies the outside of the end of the measurement at the end of the measurement of the absorbance of the specific sample, it can quickly confirm the measurement result of the absorbance of the specific sample. .

  For example, when a specific sample is a sample for which measurement by an automatic analyzer is urgent, the measurement result of the specific sample needs to be reported to a doctor or the like with priority. At this time, before reporting the measurement result to a doctor or the like, an inspection engineer or the like may check whether the measurement result is normal.

  The automatic analyzer 10 of this embodiment notifies the end of the measurement to the outside simultaneously with the end of the measurement of the absorbance of the specific specimen, and automatically displays the measurement result on the display screen. At this time, the measurement result of the specific sample is displayed on the display screen independently of the measurement result of the normal sample. Thereby, the laboratory technician or the like can check the measurement result of the specific sample on the spot without searching for the measurement result of the specific sample. As a result, it is possible to report the measurement result to a doctor or the like more quickly than before while maintaining the accuracy of the measurement result obtained by the automatic analyzer.

  In addition, for example, when the specific sample is a sample whose test result may be abnormal, the laboratory technician or the like needs to check the measurement result of the absorbance in detail over all measurement items.

  The automatic analyzer 10 can display in detail the measurement results for all the measurement items by performing a predetermined operation from the measurement results of the specific sample displayed on the display screen. Thereby, it is possible to check a specific measurement item that may cause an abnormality in the absorbance measurement result immediately after the absorbance measurement is completed. As a result, it is possible to quickly report the test result to a doctor or the like, and it is possible to reduce reporting of an erroneous test result to the doctor or the like.

  Further, when the specific sample is, for example, a sample whose measurement result by the automatic analyzer may become abnormal, it is desired to perform remeasurement (retest) by the automatic analyzer as soon as possible.

  The automatic analyzer 10 can display the absorbance measurement process in real time on the display unit 91 after the absorbance measurement of the specific specimen is started. Therefore, a laboratory technician or the like can determine a measurement abnormality during measurement of the absorbance of a specific specimen based on this real-time display. Furthermore, when a laboratory technician or the like determines a measurement abnormality, preparation for reexamination of this specific specimen can be made. That is, a laboratory technician or the like can prepare for the remeasurement of the specific sample without waiting for the end of the absorbance measurement of the specific sample. As a result, it is possible to quickly reexamine a specific sample in which an abnormality is found in the measurement result obtained by the automatic analyzer.

As shown in FIG. 15, the correspondence information between the specific information and the measurement item to be noticed is shown by associating the specific information with the number of the measurement item to be particularly noted in the specific information.

  In addition, information on a specific subject is stored in advance in the storage unit 50 as information on a specific specimen. A specific subject refers to a subject distinguished from a normal subject. Specific subjects include, for example, subjects who have a high probability of occurrence of abnormalities in the measurement results of the collected samples, subjects who need to immediately confirm the measurement results of the collected samples, and the like. The subjects listed above are specific subjects in order to distinguish them from other subjects.

  Further, when the storage unit 200 is connected to the automatic analyzer 10, a part or all of the information stored in the storage unit 50 described above may be stored in the storage unit 200.

[Detection unit]
The detection unit 60 acquires information on a specific specimen based on information on a specific subject stored in the storage unit 50. The detection unit 60 further detects the specific specimen stored in the sample container 61 in the same manner as in the first embodiment.

  That is, the detection unit 60 receives the sample ID, and acquires the subject information corresponding to the sample ID from the sample ID and the correspondence information between the sample ID and the subject information. The detection unit 60 further detects the sample container 61 in which the specific sample is accommodated by collating the information on the subject with the information on the specific subject.

  An example of correspondence information between the sample ID and the subject information is correspondence information between the specimen and the subject. The detection unit 60 acquires a sample corresponding to a specific subject from the correspondence information between the sample and the subject. The detection unit 60 acquires this sample as a specific sample.

  Moreover, the detection part 60 acquires the information of a specific specimen from specific information as shown below. First, the sample container ID of the sample container 61 is acquired by the sample container identifier reading unit 62 and the identification processing unit 42. The detection unit 60 acquires a sample ID corresponding to the acquired sample container ID based on correspondence information between the sample and the sample container stored in the storage unit 50.

  Next, the detection unit 60 acquires a subject ID corresponding to the acquired sample ID based on correspondence information between the sample and the subject stored in advance in the storage unit 50.

  Next, the detection unit 60 acquires subject information corresponding to the acquired subject ID based on correspondence information between the subject and the subject information stored in the storage unit 50 in advance.

  Next, the detection unit 60 collates the acquired subject information with the specific information stored in the storage unit 50.

  Further, the detection unit 60 acquires the measurement item to be noted from the matched specific information based on the correspondence information between the specific information and the measurement item to be noted. The detection unit 60 displays the measurement result of the absorbance of the mixed solution containing the specific specimen on the display screen of the display unit 91. On this display screen, for example, the measurement result of a notable measurement item corresponding to this specific specimen is displayed in an emphasized manner.

[Usage of automatic analyzer]
Next, the operation of the automatic analyzer 10 will be described. The usage pattern of the automatic analyzer 10 of this embodiment is the same as that of the first embodiment except for the following.

  FIG. 16 is a flowchart showing an example of the operation of the automatic analyzer 10. The automatic analyzer 10 operates to acquire a specific sample based on information on the specific sample set in advance. In this case, the information on the specific specimen is information on a specific subject. After specifying the sample corresponding to the specific sample, the automatic analyzer 10 notifies the outside of the start of the measurement when the absorbance measurement of the sample corresponding to the specific sample is started, as in the first embodiment. To work. Further, when the measurement of the specific specimen is finished, the operation is performed so as to notify the outside that the measurement has been finished. Further, after the measurement of the specific sample is completed, the measurement result is displayed on the display screen.

  First, the operator of the automatic analyzer 10 makes preparations for sample measurement by the automatic analyzer 10 (step S040). The operator inputs a subject ID corresponding to a specific subject from the operation unit 80 (step S041).

  The subject ID input from the operation unit 80 is input to the detection unit 60. Receiving this subject ID, the detection unit 60 acquires a sample ID corresponding to this subject ID from the correspondence information between the sample and the subject stored in advance in the storage unit 50 (step S042). . The detection unit 60 uses, for example, the information shown in FIG. 12 as correspondence information between the specimen and the subject. The detection unit 60 further stores the sample ID of the specific sample in the storage unit 50 as the sample ID of the specific sample (step S043). At this time, the detection unit 60 grasps that the sample ID of the specific sample is stored in the storage unit 50.

  Subsequent processing can be performed using steps S002 to S017 of the flowchart shown in FIG. 7 using the sample ID of the specific sample (steps S044 to S059). Specifically, the start and end of measurement of the specific sample are notified to the outside, and the measurement result and the like of the specific sample are displayed on the display screen of the display unit 91. In the subsequent processing, the same processing as steps S021 to S038 of the flowchart shown in FIG. 11 may be performed using the sample ID of the specific sample. Thereby, after the absorbance measurement of the specific sample is started, the measurement process is displayed in real time on the display screen, and the measurement result is displayed on the display screen after the measurement of the absorbance of the specific sample is completed.

  Further, the information input from the operation unit 80 may include other information such as measurement items in addition to information on a specific subject.

  As an example of inputting measurement items from the operation unit 80 in addition to the subject ID, for example, a case where it is desired to confirm the measurement result of a sample in which some measurement items are retested in measurement by an automatic analyzer. It is done. Further, for example, there is a high probability that an abnormality will occur in the measurement result in the measurement of a specific measurement item by the automatic analyzer. The reason is that in any case, it is necessary to track the measurement status of a sample collected from a specific subject in a specific measurement item. This is because it is necessary to specify the information of the measurement item.

  In the processing shown in the flowchart of FIG. 16, the timing at which the detection unit 60 acquires the sample ID corresponding to the sample container ID is determined when the sample container identifier reading unit 62 reads the sample container identifier of the sample container 61. Also good.

  FIG. 17 is a flowchart showing another example of the operation of the automatic analyzer 10. This automatic analyzer 10 collates the specific information set in advance with the subject information of the subject corresponding to the specimen, and when the subject information includes the particular information, the specimen is designated as the specific specimen. Works to get as. In this case, the specific information is, for example, age, specific past information, specific affliction information, or the like. Moreover, specific information can be suitably selected from what was mentioned above as a subject's personal information.

  First, the operator of the automatic analyzer 10 makes preparations for sample measurement by the automatic analyzer 10 (step S070). The operator inputs specific information for specifying a specific sample from the operation unit 80 (step S071).

  The specific information input from the operation unit 80 is input to, for example, the storage unit 50, and the detection unit 60 outputs this specific information to the storage unit 50. The storage unit 50 stores this specific information (step S072). At this time, the detection unit 60 grasps that the specific information is stored in the storage unit 50.

  Next, the detection unit 60 acquires the sample ID of the sample stored in the sample container 61 (step S073). Acquisition of the sample ID of the sample stored in the sample container 61 is performed as follows, for example. First, the sample container identifier reading unit 62 acquires read information by reading the sample container identifier attached to the sample container 61. The sample container identifier reading unit 62 outputs the acquired read information to the identification processing unit 42. The identification processing unit 42 acquires the sample container ID from the read information and outputs the sample container ID to the detection unit 60. The detection unit 60 that has received the sample container ID acquires the sample ID based on the correspondence information between the sample and the sample container stored in the storage unit 50.

  Next, the detection unit 60 acquires a subject ID corresponding to the acquired sample ID (step S074). The subject ID is acquired based on correspondence information between the specimen and the subject stored in advance in the storage unit 50.

  The detection unit 60 further acquires subject information of the subject corresponding to the obtained subject ID (step S075). The subject information is acquired based on correspondence information between the subject and the subject information stored in advance in the storage unit 50.

  The detection unit 60 collates the acquired subject information with the specific information, and determines whether there is information that matches the specific information in the acquired subject information (step S076). The specific information is stored in advance in the storage unit 50 as described above.

  In this determination, when there is information that matches the specific information in the subject information (step S076: YES), the detection unit 60 acquires a subject ID corresponding to the subject information. The detection unit 60 further acquires a sample ID corresponding to the subject ID based on correspondence information between the sample and the subject (step S077). The detection unit 60 stores the acquired sample ID as the sample ID of the specific sample in the storage unit 50 (step S078). At this time, the detection unit 60 grasps that the sample ID of the specific sample is stored in the storage unit 50. In this determination, if there is no information that matches the specific information in the subject information, the process proceeds to step S079 (step S076: NO, step S079).

  Subsequent processing can be performed in the same manner as steps S007 to S017 in the flowchart shown in FIG. 7 (steps S079 to S089). Further, the subsequent processing may be performed in the same manner as steps S026 to S038 in the flowchart shown in FIG. Thus, the display unit 91 displays the absorbance measurement process in real time on the display screen after the absorbance measurement for the specific specimen is started. Further, the display unit 91 displays the final result of the absorbance measurement on the display screen after the measurement of the specific sample is completed.

[Operation and effect of automatic analyzer]
Since the automatic analyzer 10 of this embodiment has the same configuration as that of the first embodiment, it has the same operations and effects as those of the first embodiment.

  Furthermore, the detection unit 60 automatically specifies a specific specimen from information on a specific subject. Thereby, when the sample ID of a specific subject is not known but the name of a specific subject is known, for example, by registering the name of the subject in advance, the automatic analyzer When the sample is measured by the method, the sample corresponding to the specific subject can be tracked. Thus, when it is desired to track the measurement of a sample collected from a specific subject in the measurement of the sample by the automatic analyzer, the sample can be traced without checking the sample ID corresponding to the sample.

  Further, for example, when there are a plurality of specimens of a specific subject, by registering the subject ID corresponding to the specific subject, the specimens of the subject can be registered at a time. Thereby, it is possible to register without omission even if all the sample IDs corresponding to the subject are not grasped. Furthermore, the trouble of registering and setting specimen IDs one by one can be reduced.

  In addition, the detection unit 60 automatically specifies a specific specimen from information on a specific subject. Thereby, a specific specimen can be acquired from specific information. That is, even if the information of the subject corresponding to the specimen is not grasped, for example, by registering in advance the specific information of the subject prescribed for the specific medicine, All samples can be acquired as specific samples.

  Since the detection unit 60 automatically detects the specimen of the subject corresponding to the specific information, for example, a specimen that has a high probability of occurrence of an abnormality in the measurement result can be obtained immediately without grasping the subject information one by one. Samples whose measurement results are to be confirmed are automatically set as specific samples. Therefore, in the measurement of the sample by the automatic analyzer, it is possible to know the start of measurement of these specific samples. In addition, it is possible to reduce the time and effort of inputting the sample ID and the subject ID in advance in the preparation before the measurement by the automatic analyzer.

  The configuration described in the above embodiment can be applied to clinical examination apparatuses other than the automatic analyzer.

  Examples of clinical testing apparatuses include clinical analyzers such as automatic analyzers, blood gas analyzers, electrophoresis apparatuses, and liquid chromatography apparatuses, nuclear medicine apparatuses such as radioimmunoassay apparatuses, latex agglutination reaction measuring apparatuses, and nephelometers. Blood test equipment such as immune serum test equipment, automatic blood cell counter, blood coagulation measurement equipment, microbe classification and identification equipment, bacteria culture test equipment such as blood culture test equipment and DNA / RNA measurement equipment, urine analysis equipment, fecal occult blood measurement equipment, etc. Urinalysis equipment, pathological examination equipment such as automatic tissue cell staining equipment, physiological function testing equipment, other clinical examination equipment such as micropipette, washing device dispensing device, and centrifuge.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
