Description

  The present invention relates to an automatic analyzer, and more particularly to an automatic analyzer that improves the efficiency of installing a reagent container in a reagent storage.

  Conventionally, in an automated analyzer, in order to quantify the concentration of a specimen sample such as a patient's serum, a reagent corresponding to a specific measurement item is dispensed and added to the specimen sample, and the reaction process is observed. The concentration value of each measurement item is calculated by

  The automatic analyzer includes a reagent store in which a reagent container containing a reagent is provided on a reagent disk. If reagent dispensing is required, rotate the reagent disk, move the reagent container to the dispensing point, aspirate the reagent contained in the reagent container with the reagent arm, and dispense it into the reaction tube. Note.

  In addition, a liquid level sensor for detecting the liquid level of the reagent in the reagent container is provided at the tip of the reagent probe provided in the reagent arm, and the reagent level is detected when the liquid level of the reagent is detected by the liquid level sensor. The lowering operation of the arm is stopped, and the remaining amount of the reagent in the reagent container is calculated based on the lowering amount (see, for example, Patent Document 1).

  The reagent remaining amount is displayed on the display unit as reagent information together with reagent position information (for example, reagent container number and reagent container position number).

Conventionally, when a reagent container is replaced due to a lack of remaining amount of reagent, the operator confirms the reagent position information displayed on the display unit and the reagent container on the reagent disk provided in the reagent store, while The reagent container is being replaced.

(Operation)
The operation of the automatic analyzer 100 configured as described above will be described with reference to FIGS.

  Here, an example of an operation of synchronizing the reagent container position images 151a and 151b displayed on the display unit 15 after the reagent dispensing is synchronized with the position of the reagent container 6 on the actual reagent disks 71a and 71b will be described.

  FIG. 4 is a flowchart showing the operation and operation of the automatic analyzer 100 in this embodiment. In this measurement, the case where one measurement item (in this embodiment, measurement item A) is applied to a plurality of specimens will be described.

  FIG. 5 shows an example of a selection screen for various operation modes for synchronizing the reagent container position images 151a and 151b and the reagent container positions on the actual reagent disks 71a and 71b in the automatic analyzer according to the present embodiment.

  As shown in FIG. 5, the operator selects an operation mode related to synchronization between the reagent container position images 151a and 151b and the actual positions of the reagent containers 6 on the reagent disks 71a and 71b from the input unit 16 before the measurement of the specimen sample. In the image update mode, a specific timing mode is further selected from the image update modes, and the control unit 18 performs setting based on the information (step S1 in FIG. 4).

  When the operation mode is set, the control unit 18 reads the barcode label including the reagent information attached to the reagent container 6 installed on the reagent disks 71a and 71b on the barcode reader. An instruction is given to send the reagent information and the position information of the reagent container 6 on the reagent disks 71 a and 71 b to the storage unit 17. The bar code reader executes the operation based on an instruction from the control unit 18.

  Thereafter, the operator sets the measurement item A from the input unit 16, dispenses the reagent corresponding to the measurement item A into the reaction tube 3 containing the sample sample, and starts the measurement operation (step S2 in FIG. 4).

  Thereafter, the reagent is dispensed into the reaction tube 3 from the reagent container 6 installed on the reagent disks 71a and 71b. At that time, the control unit 18 instructs the rotation drive unit 8 to rotate the reagent disks 71a and 71b based on the positional information of the reagent containers 6 on the reagent disks 71a and 71b stored in the storage unit 17. The rotation driving unit 8 rotates the reagent disks 71a and 71b based on an instruction from the control unit 18 to move the desired reagent container 6 to the reagent dispensing position. The reagent arm 9 aspirates the reagent from the reagent container 6 and dispenses it into the reaction tube 3.

  In addition, the movement information of the reagent disks 71a and 71b included in the instruction signal sent from the control unit 18 to the rotation driving unit 8 is stored in the storage unit 17 every time the rotation operation is performed, and the movement information is updated as needed.

  Thereafter, with respect to the measurement item A, the operation of dispensing the reagent into the reaction tube 3 ends (step S3 in FIG. 4).

  After the dispensing operation is completed, the control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S4 in FIG. 4).

  At this time, the position information of the reagent containers 6 on the reagent disks 71a and 71b associated with the reagent information stored in the storage unit 17 from the barcode reader before the start of the dispensing work and the reagent disks 71a and 71b during the dispensing work From the movement information, the control unit 18 recognizes the position of the reagent container on the reagent disks 71a and 71b at the end of the dispensing operation, and sends the reagent container position information to the reagent position adjusting unit.

  Based on the reagent container position information sent by the control unit 18, the reagent position adjusting unit 141 generates reagent container position images 151a and 151b corresponding to the reagent container positions on the reagent disks 71a and 71b at that time (FIG. 4). Step S5).

  The image generation unit 14 sends the reagent container position images 151a and 151b to the display unit 15, and the display unit 15 displays the reagent container position images 151a and 151b as shown in FIG. 6 (step S6 in FIG. 4).

  Further, as described above, the generation of the reagent container position images 151a and 151b by the reagent position adjusting unit 141 is not limited to the completion of the dispensing operation, but every time the reagent disks 71a and 71b rotate during the dispensing operation. Alternatively, the reagent position adjusting unit 141 matches the position of the reagent container 6 on the reagent disks 71a and 71b so that the display unit 15 can display the reagent container position images 151a and 151b every certain period of time. 151a and 151b are generated.

  FIG. 6 shows an example of updating the reagent container position images 151a and 151b corresponding to the rotation of the reagent disk in the present embodiment, and the reagent container position images 151a and 151b show the positions in the reagent storage as shown in FIG. The position of the reagent container is distinguished by attaching a number.

  In FIG. 6, the reagent container position images 151a and 151b on the reagent disks 71a and 71b are updated at the same time. However, when only one of the reagent container positions is changed by rotation, the reagent container position is changed. Only the image on the side where the image is displayed may be updated.

  FIG. 7 shows the reagent information of the reagent containers 6 installed on the reagent disks 71a and 71b with respect to the reagent container position images 151a and 151b displayed on the display screen by the display unit of the automatic analyzer according to this embodiment. An example of pasting is shown. Regarding the reagent container position images 151a and 151b indicated by the display unit 15, not only the position number in the reagent storage is pasted on the image as shown in FIG. 6, but also as shown in FIG. Various reagent information such as the remaining amount of reagent in the reagent container 6 and the shape and size of the reagent container may be affixed to the reagent container position images 151a and 151b.

  Regarding the display of the reagent container position images 151a and 151b in FIG. 7, when the shape of the reagent container 6 is displayed as A-4, C-3, or D-13, a round container is used. Show container. Further, when the size of the reagent container 6 is displayed as A-9, C-7, D-3, it indicates that it is 20 ml, and the other size is 90 ml.

  Note that the shape of the reagent container 6 that can be displayed on the reagent container position images 151a and 151b in FIG. 7 is not limited to a normal shape and a round shape. It is also possible to perform a different display distinguishable from the display showing the normal container and the round container shown in FIG.

  The above is the description of the operation for updating the reagent container position images 151a and 151b after the reagent dispensing is completed. However, the image update timing is not limited to this.

  For example, if there is a specimen sample that needs to be examined urgently during the dispensing operation, the dispensing operation may be temporarily suspended and a reagent container 6 necessary for the urgent inspection may be newly installed. It is necessary to display the reagent position images on the disks 71a and 71b. The operation in that case will be described with reference to FIG.

  Since steps S1 and S2 in FIG. 8 are the same as steps S1 and S2 in FIG. 4 described above, a description thereof will be omitted, and a description after step S3 in FIG. 8 will be given.

  During the dispensing operation, the operator presses an interruption button (not shown) provided on the input unit 16. An instruction signal is sent from the control unit 18 to the rotation drive unit 8, and according to the instruction signal, the rotation drive unit 8 stops the rotation of the reagent disks 71a and 71b, and the reagent arm 9 interrupts the reagent dispensing operation (FIG. 8 step S3).

  If there is a reaction tube 3 into which only the specimen sample has been dispensed when the interrupt button is pressed, the rotation drive unit 8 stops the reagent disks 71a and 71b after dispensing of the reagent to the reaction tube 3 is completed. Let

  After the dispensing operation is interrupted, the control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S4 in FIG. 8).

  Based on the reagent container position data recognized by the control unit 18, the reagent position adjusting unit 141 generates reagent container position images 151a and 151b corresponding to the reagent container positions on the reagent disks 71a and 71b at that time (FIG. 8 step S5).

  The image generation unit 14 sends the reagent container position images 151a and 151b to the display unit 15, and the display unit 15 displays the reagent container position images 151a and 151b on the display screen 151 as shown in FIG. 3 (step S6 in FIG. 8). ).

  Furthermore, as another image update timing, there is a time when the operator instructs an image update from the input unit 6. The operation in that case will be described with reference to FIG.

  Note that steps S1 and S2 in FIG. 9 are the same as steps S1 and S2 in FIG. 4 described above, and thus description thereof will be omitted, and description after step S3 in FIG. 9 will be given.

  An image update button (not shown) provided in the input unit 16 is pressed to send an image update instruction signal to the control unit 18 (step S3 in FIG. 9).

  Based on the instruction signal from the input unit 16, the control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S4 in FIG. 9).

  Based on the reagent container position data recognized by the control unit 18, the reagent position adjusting unit 141 generates reagent container position images 151a and 151b corresponding to the reagent container positions on the reagent disks 71a and 71b at that time (FIG. 9 step S5).

  The image generation unit 14 sends the reagent container position images 151a and 151b to the display unit 15, and the display unit 15 displays the reagent container position images 151a and 151b on the display screen 151 as shown in FIG. 3 (step S6 in FIG. 9). ).

  Here, when inputting the data of the reagent container 6, if there is no barcode reader or the barcode label is not attached to the reagent container, the reagent information is registered without directly inputting the reagent information from the input unit 16. An example of processing based on the reagent information will be described. In this embodiment, the control unit 18 is provided with a reagent information processing unit (not shown), and the storage unit 17 is provided with a reagent information table 171.

  As shown in FIG. 10, the reagent information table 171 includes information on the reagent ID, reagent type, container size (capacity), and container shape for various reagents. With reference to this reagent information table 171, the reagent information processing unit registers information related to the reagent container 6 installed on the reagent disks 71a and 71b.

  Each of the reagent containers 7a and 7b is provided with a lid (not shown), and when the operator opens the lid, the rotation drive unit 8 stops the rotation of the reagent disks 71a and 71b. The reagent container position images 151a and 151b corresponding to the positions of the reagent containers 6 on the reagent disks 71a and 71b may be generated, and the display unit 15 may display these images.

  The rotation driving unit 8 stops the rotation of the reagent disks 71a and 71b triggered by pressing a lid opening / closing switch (not shown), and the reagent container corresponding to the reagent container position on the reagent disks 71a and 71b at that time. The position images 151a and 151b may be generated and displayed.

(effect)
Such an automatic analyzer 100 can increase the efficiency of the installation work of the reagent container 6. In addition, by updating the reagent container position images 151a and 151b when the reagent dispensing operation is interrupted or at an arbitrary timing, the image can be referred to when the operator wants to grasp the reagent container position.

  In addition, by indicating the shape and size of the reagent container 6 in the reagent container position images 151a and 151b, the reagent can be replaced based on the display of the shape and size shown in the reagent container position images 151a and 151b. It is possible to prevent time mistakes.

  Further, by indicating the shape and size of the reagent container 6 in the reagent container position images 151a and 151b, the reagent container position image 151a and 151b can be matched with the reagent container position images 151a and 151b after the rotational movement. Reagent replacement can be performed based on the display of the shapes and sizes shown in 151a and 151b, and it is possible to prevent mistakes during reagent replacement.

  Further, by using the interruption button, when there is a sample sample that requires an urgent examination during the dispensing operation, the reagent container 6 necessary for the examination can be easily installed.

  Also, by using the image update button, it is possible to update the image of the reagent container position images 151a and 151b at the timing desired by the operator, and the remaining amount of the reagent in the reagent container 6 can be grasped during the dispensing operation. Easy to do.

  In addition, by providing the automatic analyzer 100 with the reagent information table 171 as shown in FIG. 7, it is possible to easily input reagent information regarding the reagent container 6 to which no barcode label is attached.

(Modification 1 of Example 1)
In the first modification of the first embodiment, a modification in which the reagent container position images 151a and 151b are automatically updated at regular intervals during the dispensing operation is described with respect to the first embodiment in which the image is updated at a specific timing. To do.

(Constitution)
Since the description of the configuration of the automatic analyzer 100 is given in the above-described first embodiment, the description other than the input unit 16 having a new function in this embodiment is omitted.

  In this modified example, the input unit 16 synchronizes the reagent container positions on the reagent disks 71a and 71b and the reagent container position images 151a and 151b displayed on the display unit 15 as in the first embodiment. The image update mode can be selected, and the specific timing mode can be selected from the image update mode. Furthermore, in this modified example, it is possible to newly select the constant time mode and the rotation frequency mode from the image update mode.

  Here, first, a case where image updating is performed at regular intervals will be described with reference to FIG.

  FIG. 11 is a flowchart illustrating operations and operations of the automatic analyzer 100 according to the first modification of the first embodiment.

  As shown in FIG. 5, the operator previously sets the operation mode from the input unit 16 to the image update mode and further from the image update mode to the fixed time mode before measuring the sample (step S1 in FIG. 11).

  Note that an image update time interval is set in advance. In this embodiment, the time is defined as X minutes. The time interval data is sent to the storage unit 17 and stored.

  Thereafter, the operator sets a desired measurement item from the input unit 16 and starts dispensing and measurement work on the specimen sample (step S2 in FIG. 11).

  After starting the dispensing of the reagent to the specimen sample, the control unit 18 starts measuring time and determines the elapse of the time set previously (step S3 in FIG. 11).

  Each time the set time (X minutes in this embodiment) elapses, the control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S4 in FIG. 11).

  Based on the reagent container position data recognized by the control unit 18, the reagent position adjusting unit 141 generates reagent container position images 151a and 151b corresponding to the reagent container positions on the reagent disks 71a and 71b at that time (FIG. 11 step S5).

  The image generation unit 14 sends the reagent container position images 151a and 151b to the display unit 15, and the display unit 15 displays the reagent container position images 151a and 151b on the display unit 15 as shown in FIG. 3 (step S6 in FIG. 11). ).

  In addition, after the end of dispensing, the same processing as the image updating operation at the timing after the end of dispensing in Example 1 is performed, and the reagent container position images 151a and 151b are updated.

  Next, the case where the image is updated for every fixed number of rotational movements of the reagent disks 71a and 71b will be described with reference to the flowchart showing the operation and operation of the automatic analyzer 100 in FIG.

  As shown in FIG. 5, the operator previously sets the operation mode from the input unit 16 to the image update mode and further from the image update mode to the rotation frequency mode before measuring the specimen (step S1 in FIG. 12).

  It should be noted that the number of rotational movements of the reagent disks 71a and 71b, which is a guideline for timing of image update, is set in advance. Here, the number of rotational movements indicates the number of times that the reagent disks 71a and 71b have been rotated by the rotation driving unit 8. In this embodiment, the number of rotational movements is defined as Y times. The data of the number of rotations is sent to the storage unit 17 and stored.

  Thereafter, the operator sets a desired measurement item from the input unit 16 and starts dispensing and measurement work on the specimen sample (step S2 in FIG. 12).

  After starting the dispensing of the reagent to the specimen sample, the control unit 18 starts the number of rotations of the reagent disks 71a and 71b, and determines whether or not the number of rotations set previously has been reached (step S3 in FIG. 12).

  Each time the reagent disks 71a and 71b are rotated, the controller 18 recognizes the position of the reagent container on the reagent disks 71a and 71b at that time (see FIG. 12). Step S4).

  In this embodiment, the determination as to whether or not the set number of rotational movements has been reached moves to the operation of recognizing the reagent container position and the operation after step S5 when both the reagent disks 71a and 71b are reached. The present invention is not limited, and any one of the reagent disks 71a and 71b may be reached.

  Based on the reagent container position data recognized by the control unit 18, the reagent position adjusting unit 141 generates reagent container position images 151a and 151b corresponding to the reagent container positions on the reagent disks 71a and 71b at that time (FIG. 12 step S5).

  When the reagent container position on the reagent disks 71a and 71b is recognized when either one of the reagent disks 71a and 71b moves by the preset number of rotations in step S4 of FIG. The container position images 151a and 151b are also generated so as to update only the image on the side that has reached the number of rotational movements.

  The image generation unit 14 sends the reagent container position images 151a and 151b to the display unit 15, and the display unit 15 displays the reagent container position images 151a and 151b on the display screen 151 as shown in FIG. 3 (step S6 in FIG. 12). ).

  Note that the method for determining the image update timing according to the rotational movement of the reagent disks 71a and 71b is not limited to this. For example, the reagent disks 71a and 71b are rotationally moved more than a certain angle from the home position of the reagent disks 71a and 71b. The image may be updated at that time.

  Here, the “home position” refers to a specific rotational position with respect to the reagent disks 71a and 71b. For example, the reagent disk 71a in which the reagent container is arranged at the same position as the reagent container position images 151a and 151b in FIG. , 71b is the home position.

(effect)
Such an automatic analyzer 100 makes it possible to increase the efficiency of the installation work of the reagent container 6, and the reagent container position images 151a and 151b can be obtained after the reagent dispensing is completed, or at a certain time interval and the number of rotational movements. By automatically updating, the operator can grasp the position of the reagent container 6 without performing a manual operation. Furthermore, by updating the reagent container position images 151a and 151b, the time required to rotate the actual reagent disks 71a and 71b can be saved.

(Modification 2 of Example 1)
In the second modification of the first embodiment, a modification in which the reagent container position images 151a and 151b are automatically updated at regular intervals during the dispensing operation is described with respect to the first embodiment in which the image is updated at a specific timing. To do.

(Constitution)
Since the description of the configuration of the automatic analyzer 100 has been given in the above-described first and second embodiments, descriptions other than the feed switch 162 newly provided in the input unit 16 in this embodiment will be omitted.

  In this modification, the control unit 18 includes a rotation drive control unit 181, and the image generation unit 14 includes a reagent position adjustment unit 141.

  In this embodiment, as shown in FIG. 13, when the reagent container 6 is installed on the reagent disks 71a and 71b, a feed switch 162 for moving the reagent container 6 to a position where the operator can easily work is provided as a reagent disk 71a, It arranges in the vicinity of 71b.

  The feed switch 162 sends an instruction to the rotation drive control unit 181 of the control unit 18, receives a control signal from the rotation drive control unit 181 based on the instruction, and the rotation drive unit 8 rotates the reagent disks 71a and 71b.

  The reagent position adjusting unit 141 receives rotation information of the reagent disks 71a and 71b from the rotation drive control unit 181 and generates an image related to the position information of the reagent container 6 based on the information.

(Operation)
The operation of the automatic analyzer 100 configured as described above will be described.

  Here, after the dispensing of the reagent is completed, the reagent container position in the actual reagent disks 71a and 71b is rotated to a desired position using the feed switch 162, and the reagent container position displayed on the display unit 15 at the position after the rotation. An example of the operation for synchronizing the two will be described with reference to FIG.

  FIG. 14 is a flowchart illustrating operations and operations of the automatic analyzer 100 according to the first modification of the first embodiment. In this measurement, a case where one measurement item (here, measurement item A) is applied to a plurality of specimens will be described.

  The operator sets the operation mode to the reagent storage movement mode and the reagent disk movement mode to the reagent disk manual movement mode from the input unit 16 in advance before measuring the sample (step S1 in FIG. 14). Thereafter, the operator sets a desired measurement item A from the input unit 16 and starts dispensing and measuring work on the specimen sample (step S2 in FIG. 14).

  With respect to the measurement item A, the operation of dispensing the reagent into the reaction tube 3 containing the specimen sample is completed (step S3 in FIG. 14). The operator uses the feed switch 162 to rotate the reagent disks 71a and 71b to move them to desired positions (step S4 in FIG. 14). After the movement of the reagent disks 71a and 71b by the feed switch 162 is completed, the control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S5 in FIG. 14). Based on the reagent container position, the rotation drive control unit 181 generates reagent container position images 151a and 151b at the same positions as the moved reagent disks 71a and 71b (step S6 in FIG. 14). The reagent container position images 151a and 151b generated again are sent to the display unit 15 and displayed on the display screen 151 (step S7 in FIG. 14).

  Note that the movement of the reagent disks 71a and 71b is not limited to using the feed switch 162, but the reagent container 6 that needs to be replaced due to a lack of reagents based on the reagent remaining amount information from the dispensing arm. The rotation drive unit 8 rotates and moves the reagent disks 71a and 71b so that the operator moves to a position where the operator can easily replace (for example, the front side of the operator), and then the reagent container position images 151a and 151b are moved to the reagent. The reagent position adjustment unit 141 may perform adjustment so as to synchronize with the reagent container positions on the disks 71a and 71b, and the display unit 15 may display the adjusted reagent container position images 151a and 151b.

  In the above-described operation, the reagent container position images 151a and 151b displayed after the reagent dispensing is updated. However, the image update timing is not limited to this.

  For example, if there is a specimen sample that needs to be examined urgently during the dispensing operation, the dispensing operation may be temporarily suspended and a reagent container 6 necessary for the urgent inspection may be newly installed. The reagent container positions on the reagent disks 71a and 71b are rotated to a desired position using the feed switch 162, and the reagent container position images 151a and 151b displayed on the display unit 15 are synchronized with the positions after the rotation. Thereafter, the reagent container 6 is installed.

(effect)
Such an automatic analyzer can increase the efficiency of the installation work of the reagent container 6. Further, the operator moves the reagent container position on the reagent disks 71a and 71b to a desired position by the feed switch 162, and further synchronizes the reagent container position images 151a and 151b with the position, so that the operator can change the position. The position of the necessary reagent container 6 can be easily grasped.

  In this embodiment, the reagent container position on the automatic analyzer 100 side is made to correspond to the reagent container position on the screen, the reagent disks 71a and 71b are rotated, and the reagent container positions on the reagent disks 71a and 71b of the automatic analyzer 100 are rotated. An example of synchronizing the reagent container position on the display screen 151 will be described.

(Constitution)
Since the description of the configuration of the automatic analyzer 100 is given in the above-described first embodiment, descriptions of the control unit other than the control unit 18 having a new function in this embodiment are omitted.

  The image generation unit 14 having the reagent position adjusting unit 141 in the first embodiment may not have the reagent position adjusting unit 141 in the present embodiment.

  In this embodiment, as shown in FIG. 15, the control unit 18 includes a rotation drive control unit 181.

  The rotation drive control unit 181 instructs the rotation drive unit 8 to return the reagent container positions on the reagent disks 71a and 71b to the home position.

  In this embodiment, “home position” has the same definition as in the first modification of the first embodiment.

(Operation)
The operation of the automatic analyzer 100 configured as described above will be described.

  Here, an example of the operation of returning the actual reagent container position on the reagent disks 71a and 71b to the home position after the dispensing of the reagent will be described with reference to FIG. In this measurement, a case where one measurement item (here, measurement item A) is applied to a plurality of specimens will be described.

  As shown in FIG. 16, the operator sets the operation mode to the reagent storage movement mode and the reagent storage movement mode to the home position mode in advance from the input unit 16 before measuring the sample (step S1 in FIG. 17). Thereafter, the operator sets a desired measurement item A from the input unit 16 and starts dispensing and measurement work on the sample (step S2 in FIG. 17). With respect to the measurement item A, the operation of dispensing the reagent into the reaction tube 3 containing the specimen sample is completed (step S3 in FIG. 17). The control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S4 in FIG. 17). Based on the reagent container position, the rotation drive control unit 181 instructs the rotation drive unit 8 to rotate the reagent disks 71a and 71b to the home position. Based on the instruction, the rotation drive unit 8 rotates and moves the reagent disks 71a and 71b to the home position (step S5 in FIG. 17).

  In this way, the reagent container positions on the reagent disks 71a and 71b and the reagent container position images 151a and 151b are synchronized. In the above-described operation, the reagent disks 71a and 71b are rotated to the home position after the reagent dispensing is completed, but the timing is not limited to this.

  For example, when there is a specimen sample that needs to be urgently examined during the dispensing operation, the dispensing operation may be temporarily suspended and a reagent container 6 necessary for the urgent inspection may be newly installed. The internal reagent container position is returned to the home position, and the reagent container 6 is installed.

(effect)
Such an automatic analyzer 100 can increase the efficiency of the installation work of the reagent container 6. Further, by moving the reagent disks 71a and 71b to the home position, the operator can easily grasp the position of the reagent container 6 that needs to be replaced.

(Modification of Example 2)
In the modification of the second embodiment, in order to synchronize the reagent container positions on the reagent disks 71a and 71b of the automatic analyzer 100 and the reagent container positions on the display screen 151, the reagent container position on the screen and the automatic analyzer side An example in which both of the reagent container positions are moved to correspond to the home position will be described.

  The “home position” in the present embodiment refers to a specific rotational position with respect to the reagent disks 71a and 71b. Unlike the first and second modifications of the first embodiment, the home position is set in this modification. can do.

(Constitution)
Since the description regarding the configuration of the automatic analyzer 100 has been given in the first embodiment and the second embodiment described above, descriptions other than the input unit 16 having a new function in this embodiment are omitted.

  In this embodiment, the control unit 18 includes a rotation drive control unit 181, and the image generation unit 14 includes a reagent position adjustment unit 141.

  In the present embodiment, as shown in FIG. 18, the input unit 16 includes a default position setting unit 161.

  The predetermined position setting unit 161 has a function of setting the home position when both the reagent container position on the screen and the reagent container position on the automatic analyzer side are moved to correspond to the home position. The rotation drive control unit 181 and the reagent position adjusting unit 141 act so as to synchronize with the home position set by the default position setting unit 161.

(Operation)
The operation of the automatic analyzer 100 configured as described above will be described with reference to FIG.

  Here, an example of an operation for moving the reagent container position on the screen and the reagent container position on the automatic analyzer side to correspond to the home position after dispensing of the reagent will be described.

  In this measurement, a case where one measurement item (here, measurement item A) is applied to a plurality of specimens will be described.

  The operator sets the operation mode to the reagent storage movement mode and the reagent storage movement mode to the reagent storage / image adjustment mode from the input unit 16 in advance before measuring the sample (step S1 in FIG. 19).

  The operator previously sets the same home position where the reagent disks 71a and 71b and the reagent container position images 151a and 151b move from the default position setting unit 161 included in the input unit 16.

  Thereafter, the operator sets a desired measurement item A from the input unit 16 and starts dispensing and measurement work on the specimen sample (step S2 in FIG. 19).

  With respect to the measurement item A, the operation of dispensing the reagent into the reaction tube 3 containing the specimen sample is completed (step S3 in FIG. 19).

  The control unit 18 recognizes the reagent container positions on the reagent disks 71a and 71b at that time (step S4 in FIG. 19).

  Based on the reagent container position, the rotation drive control unit 181 instructs the rotation drive unit 8 to rotate the reagent disks 71a and 71b to preset positions set in advance. Based on the instruction, the rotation drive unit 8 rotates the reagent disks 71a and 71b and moves them to the predetermined positions (step S5 in FIG. 19).

  In addition, the reagent position adjusting unit 141 generates the reagent container position images 151a and 151b again according to the preset default position (step S6 in FIG. 19).

  The reagent container position images 151a and 151b generated again are sent to the display unit 15 and displayed on the display screen 151 (step S7 in FIG. 19).

  In the above-described operation, the reagent position image displayed after the dispensing of the reagent is updated, but the image update timing is not limited to this.

  For example, if there is a specimen sample that needs to be examined urgently during the dispensing operation, the dispensing operation may be temporarily suspended and a new reagent container 6 necessary for the urgent inspection may be installed. The reagent container position on the screen and the reagent container position on the automatic analyzer side are moved to the home position determined by the predetermined position setting unit 161, and the reagent container 6 is installed.

(effect)
Such an automatic analyzer 100 can increase the efficiency of the installation work of the reagent container 6. In addition, by inputting the operator's desired position in advance and automatically moving the reagent container position on the actual reagent disks 71a and 71b and updating the reagent container position images 151a and 151b, the operator can replace the reagent container. The position of the necessary reagent container 6 can be easily grasped.
