PROBLEM TO BE SOLVED: To display data measured before a next inspection period after the previous inspection and data measured at a period beyond the next inspection period in different formats from each other when displaying a result of measurement by medical equipment.SOLUTION: An information processing device has: a QC management DB 304b for storing device identification information for specifying medical equipment and identifying it and inspection history information showing an inspection performance day of the medical equipment identified by the device identification information; and a medical record DB 304a for storing biological information, time and date information when the biological information is measured, and device identification information for specifying medical equipment used for measurement as medical record information of a patient. A CPU 301 refers to the DB when there is an instruction of transition display along a time axis of the patient's biological information, determines whether reliability of a measurement date of individual biological information is "high" or "low", displays biological information of "high" reliability and biological information of "low" reliability in different formats, and graphically displays it along the time axis.

Description

  The present invention relates to a medical device management technique for measuring biological information represented by a blood glucose meter or the like.

  Blood glucose meters and electronic sphygmomanometers are medical devices that measure biological information. In the case of a blood glucose meter, there are several methods for measuring, but blood is sampled, light is applied to a filter through which blood penetrates, and the blood glucose level is measured from the reflected light (Patent Document 1). .

  In the case of such a blood glucose meter, in order to ensure the credibility (or reliability) of the measurement result, in general, QC (Quality Control) inspection is performed periodically, for example, for a predetermined period (for example, one month). In the QC check, a sample having a known blood glucose level is actually measured, whether or not the difference between the measurement result and the sample is within the allowable range is checked, and if it is within the allowable range, the use is continued. If a measurement result exceeding the allowable range is obtained, the manufacturer is requested to repair or replace parts.

  In the case of an electronic sphygmomanometer, when a medical worker uses a manually pressurized sphygmomanometer in a hospital or the like, the sphygmomanometer body and the air balloon are operated with one hand. If the sphygmomanometer body is vibrated or the sphygmomanometer body and the air balloon are dropped, the adjusted semi-fixed resistor will move and cause a deviation in the adjustment value. Adjustment is required.

  However, even on the scheduled check date, the user may forget to check and continue to use the medical device. If you check immediately and find out that it is normal, there is no problem, but if you do not notice that it is abnormal, you may not be able to make a correct diagnosis and examination. However, on the other hand, it should be noted that there is a fact that the measurement was continued without checking even on the scheduled check date.

  For example, consider the case of browsing past measurement results up to the present time, such as to make a future treatment policy for a patient. Neglecting the inspection eventually results in a mixture of measured data that has been shallow since the previous inspection date and data that was measured even though it was already in the inspection period. Otherwise, it may interfere with correct diagnosis and examination.

  The present invention has been made in view of such problems, and when displaying the results measured with a medical device represented by a blood glucose meter, the data measured between the previous check and the next check time, It provides a technology that displays data measured at a time exceeding the inspection time in a different form, makes the level of reliability of the measurement data obvious and makes it possible to perform correct diagnosis and diagnosis.

In order to solve the problem, the medical device management system of the present invention has the following configuration. That is,
An information processing system for displaying a measurement result of a medical device that measures biological information of a patient,
First storage means for storing device identification information for identifying a medical device, and inspection history information representing a date of inspection of the medical device specified by the device identification information;
A second storage unit that stores biometric information, date and time information on which the biometric information is measured, and device identification information that identifies a medical device used for the measurement, as patient chart information;
When there is a transition display instruction along the time axis of the patient's biological information, the inspection history information of the medical device specified by the device identification information stored in the second storage unit is the first history information. Search means for searching from storage means;
From the inspection history information obtained by searching by the search means, for each measurement date of the individual biological information, the most recent inspection execution date before the measurement date is extracted, and from the extracted inspection execution date Deriving the next scheduled inspection date after the inspection cycle,
The measurement date of each biometric information is compared with the next scheduled inspection date derived for each, and the biometric information on the measurement date before the next inspection has a reliability of “high”, the measurement date exceeding the next inspection date Biometric information of the reliability determination means for determining that the reliability is "low",
According to the determination result of the reliability determination means, display control means for displaying biological information with high reliability and biological information with reliability “low” in different display forms and graphically displaying them along the time axis Have.

  According to the present invention, when displaying the result measured by a medical device typified by a blood glucose meter, the data measured from the previous inspection to the next inspection time and the time exceeding the next inspection time. The measured data is displayed in a different form, and the level of reliability of the measured data becomes clear at a glance. Based on the correct measurement result, the doctor can perform correct diagnosis and diagnosis.

  Among these, the A / D converter 250 A / D converts the photometric value data generated in the light receiving element 232 and supplies the A / D converter 250 with the A / D converter 250.

  The control unit 240 includes a CPU 241 that controls the entire apparatus and a storage unit 242. The storage unit 242 calculates blood glucose level data based on various programs (photometric value data input via the A / D converter 250) executed by the CPU 241 in order to realize the function as the blood glucose measurement device 100. Program, data recording, and communication program with an external device), voice messages, and warning sound data.

  In addition to the program and data as described above, an area for storing device information 245 and measurement data 246 is secured in advance in the storage unit 242 as illustrated. Note that the storage unit 242, particularly the area for storing the measurement data 246, is composed of a writable nonvolatile memory, and even when the power is turned off, the data is stored and does not volatilize. The device information 245 may be stored in a mask ROM so that it cannot be rewritten.

  The measurement data 246 is divided for each measurement date and measurement time zone, and is further associated with an identifier indicating whether the blood glucose measurement was performed before or after the meal (that is, according to the measurement timing). Are separated).

  The device identification information 245 is information for uniquely identifying the blood glucose measurement device 100 and is also written by the manufacturer.

  The display control unit 260 controls to display a predetermined screen (a screen for displaying calculated blood glucose level data or information indicating the internal state of the control unit 240) on the display unit 114 based on a display instruction from the control unit 240. To do. The operation unit 270 receives instructions from the power switch 113, the history call button 115, the play button 116, and the post-meal button 117 in FIG. 1, and transmits the received instructions to the control unit 240.

  The communication unit 280 is a non-contact communication means of a short distance up to about 10 cm (for example, power saving IC communication technology of ISO / IEC 14443, communication technology of ISO / IEC 18092, FeliCa (registered trademark of Sony Corporation)) Communication technology. Via this communication unit 280, communication is performed with an RFID reader / writer installed in a hospital or the like and connected to a dedicated terminal handled by a doctor or the like. In the communication technology of FeliCa, communication is performed using radio waves of 13.56 MHz, and communication of 100 to 400 kbps is performed in a very short distance up to about 10 cm without contact.

  The configuration of the blood glucose meter in the embodiment has been described above. The blood glucose measurement device in the embodiment is lent to a patient from a hospital or the like. A patient brings the blood glucose measuring device to a hospital at intervals of about one week, for example, and is examined. On the hospital side, the blood glucose level measurement result after the previous examination, which is biological information, is read from the blood glucose measurement device brought by the patient using a dedicated terminal, and is registered in the database for each patient. The doctor sees the blood glucose level database and makes a medical examination.

<Outline of Dedicated Terminal (Information Processing Device) 200 and Explanation of Communication with Blood Glucose Measuring Device 100>
Next, the configuration of the dedicated terminal installed in the hospital and the flow of processing will be described. FIG. 3 shows an information processing apparatus 200 that functions as a dedicated terminal handled by a doctor or the like in a hospital, a proximity wireless communication unit 250 including an RFID reader / writer connected thereto, and blood glucose measurement in the proximity wireless communication unit 250 A system configuration is shown in which communication is performed while holding an apparatus 1100.

  The information processing apparatus 200 may be a personal computer, for example, and its configuration is as shown in FIG. In the figure, 301 is a CPU that controls the entire apparatus, 302 is a ROM that stores a BIOS and a boot program, and 303 is a RAM that is used as a work area of the CPU 301 and loads an OS and various application programs. . Reference numeral 304 denotes a hard disk device (hereinafter referred to as HDD) that functions as an external storage device, which includes an OS, application programs according to FIGS. 7, 9, and 10 described later, and a medical record database (hereinafter referred to as medical record DB) as shown in the figure. 304a, a QC management DB 304b for managing the history of the QC inspection date of each blood glucose measurement device is stored in advance. 305 is a keyboard, 306 is a pointing device such as a mouse, 307 is a display device such as a liquid crystal display, 308 is a network interface, and 309 is a proximity wireless communication unit that communicates with the blood glucose measuring device 100 as described above (Specifically, an RFID reader / writer). Here, QC is an abbreviation for Quality Control.

  FIG. 5 shows an example of the data structure of the medical record DB (second storage means) 304a of the embodiment having the above configuration. As shown in the figure, the medical record DB 304a is managed as data for each individual patient. For one patient, an area 501 for storing a chart number for identifying and identifying the chart, an area 502 for storing basic information of the patient's name, sex, date of birth, age, and address, blood glucose An area 503 for storing a value is provided. The data for one record stored in the area 503 includes measurement date and time, measured blood glucose level (unit: mg / dl), and device identification information for identifying and identifying the blood glucose measuring device 100 that measured the blood glucose level. (Corresponding to reference numeral 245 in FIG. 2). The storage order is the measurement date order. In addition to the above, information related to the patient's past treatment and measured data (blood pressure, etc.) is stored. However, in this embodiment, only the blood glucose level is described. Not specifically shown.

  The details of the process for registering the measurement result held in the blood glucose measurement device 100 in the medical record DB 304a will be described later, but the outline is as follows.

  First, an operator (such as a doctor) operates the keyboard 305 and the pointing device 306 to start an application that accesses the medical record DB 304a. After the activation, the operator searches the medical record DB 304a using the patient name, medical chart number, and the like as keys, displays the patient's medical chart on the display device 307, and confirms the identity of the patient. Next, “read blood glucose data reading” is selected from a menu (not shown), and the blood glucose measuring device 100 received from the patient is held over the proximity wireless communication unit 250 or placed on the proximity wireless communication unit 250. Do.

  In addition, when “Graph display of blood glucose level” is selected from this menu, a graph showing the transition of blood glucose level over a period of time for the corresponding patient is displayed. The description will be continued on the assumption that “data read in” is selected.

  When “read data of blood glucose measurement device” is selected, the CPU 301 starts communication with the blood glucose measurement device 100 via the proximity wireless communication unit 250. Thereafter, the CPU 301 requests batch transfer of the contents of the measurement data 246 from the blood glucose measurement device 100 and also requests device identification information 245. In response to these requests, the CPU 241 in the blood glucose measurement device 100 transmits measurement data 246 and device identification information 245 to the information processing device 200 via the communication unit 280. The CPU 301 in the information processing apparatus 200 adds the received measurement data to the blood glucose level data storage area 503 of the corresponding chart DB. At this time, all the measurement data received this time (generally data for one week) may be regarded as being measured by one blood glucose measurement device 100 held over the close proximity wireless communication unit 250. The device identification information 245 of the received blood glucose measurement device is assigned to the value and stored.

  On the other hand, the QC management DB (first storage means) 304b in the embodiment is managed for each blood glucose measuring device as shown in FIG. 6, and is a device identification for identifying and identifying the blood glucose measuring device. An area 601 for storing information (reference numeral 245 in FIG. 2) and an area 602 for storing QC inspection implementation dates in the past in order of date.

  The update of the QC management DB 304b is performed by executing an update application program (stored in the HDD 304) of the QC management DB after actually performing a QC check. In the QC check, a sample having a known blood glucose level is actually measured by a target blood glucose measurement device, and it is inspected whether the difference between the measurement result and the blood glucose level indicated by the sample is within an allowable range. If it is within the acceptable range, continue to use it. If a measurement result exceeding the allowable range is obtained, the manufacturer is requested to repair or replace parts. In the former case, the date when it is determined that no abnormality is found is the QC inspection date. In the latter case, the date of repair by the manufacturer is registered as the QC inspection date. This is to make it the reference date for the next QC inspection. Note that the next scheduled QC inspection date in the embodiment is described as preferably one month after the previous QC inspection implementation date (that is, preferably inspection every one month). The monthly check is done when the patient goes to the hospital, and the QC check can be done when the patient goes to the hospital, and if it is less than one month, the patient must visit the hospital for the QC check. This is because it is difficult to ensure the measurement accuracy of the blood glucose measurement device.

  FIG. 7 is a flowchart showing an execution procedure of an application program for updating the QC management DB 304b. The processing of the CPU 301 will be described below according to this flowchart.

  First, in step S701, device identification information is input. In the embodiment, the device identification information may be input from the keyboard 305, but is input by holding the blood glucose measurement device 100 over the close proximity wireless communication unit 250. That is, when CPU 301 detects that communication with blood glucose measurement device 100 is possible via proximity wireless communication unit 250, CPU 301 requests blood glucose measurement device 100 to transmit device identification information and receives it. As a result, the blood glucose measurement device 100 to be updated can be uniquely identified, and the data related to the corresponding blood glucose measurement device 100 in the QC management DB 304b can be specified. The CPU 301 searches the area 601 in the QC management DB 304b using the input device identification information as a key, and searches for data having matching device identification information.

  Next, in step S702, the CPU 301 causes the keyboard 305 to input a QC inspection date. When this input is performed, the CPU 301 proceeds to step S703, adds the input QC check date to the end of the region 602 of the blood glucose measurement device obtained by the search, and updates the QC management DB 304b. Then, this process is finished.

<Description of blood glucose level graph display>
Next, a process when the patient's medical chart display is performed and then “Graph display of blood glucose level” is selected will be described. Upon receiving this selection, the CPU 301 displays a blood glucose level graph display window (hereinafter simply referred to as a window) 800 as shown in FIG. The window 800 includes an area 801 for displaying a graph, an area 802 for inputting a start date and an end date of a period to be displayed, an area 803 for displaying an average value, a maximum value, and a minimum value of blood glucose levels during the period, and Message area 804.

  Immediately after selecting the “display blood glucose level graph”, these areas are blank, but if the user operates the keyboard 305 to enter the start date and end date of the period in the area 802, the blood glucose level for that period is displayed. Is read from the area 503 of the chart DB 304a and displayed as a line graph, and the average value, maximum value, minimum value, etc. of the blood glucose level during that period are calculated and displayed in the area 803.

  Here, the display processing of the line graph in the area 801 by the CPU 301 will be described in more detail.

When the CPU 301 in the present embodiment draws a line graph based on the blood glucose level in the period specified in the area 802, first, it obtains the device identification information of the blood glucose measuring device that measured each blood glucose level (see FIG. 5). Then, the CPU 301 reads the QC inspection date history information (information in the area 602 of FIG. 6) of the corresponding blood glucose measurement device by searching the QC inspection management DB 304b using the device identification information as a key. Assume that the blood glucose measurement date of the line graph to be drawn indicates January 15, 2012. In the embodiment, since it is assumed that QC inspection is performed at a cycle of one month, the QC inspection date that is the measurement date “January 15, 2012” and closest to the measurement date is read. Identify from the history. Then, it is determined whether or not “January 15, 2012” is included within one month from the specified QC check date, and one of the following (1) and (2) is determined according to the determination result. According to the above, a straight line part constituting the line graph is drawn.
(1) If “January 15, 2012” is within one month from the specified QC check date, the blood glucose level measured on “January 15, 2012” is credible (reliability “ High ”). Therefore, a straight line connecting the blood glucose level measured immediately before (in most cases, the previous day) and the blood glucose level of “January 15, 2012” of interest is drawn.
(2) If “January 15, 2012” is longer than one month from the specified QC check date, the blood sugar level measured on “January 15, 2012” is the QC check. Although it was a time when it should have been, it is a result of measurement without implementing it, and it can be said that the reliability is “low”. Therefore, a straight line connecting the blood glucose level measured immediately before (in most cases, the previous day) and the blood glucose level of “January 15, 2012” of interest is drawn. Further, when at least one includes a broken line segment, the CPU 301 displays a message for calling attention in the area 804.

  In the case of FIG. 8, the line graph in the region 801 shows a line part 801a indicated by a solid line and a line part 801b indicated by a broken line. That is, it can be seen that data that cannot be said to be highly credible are mixed in the line graph of the blood glucose level during the designated period. Further, since a message indicating the reason for the presence of the broken broken line is displayed in the area 804, it is easy to visually recognize the difference from highly reliable data, so that diagnosis can be performed in consideration thereof. In the case of FIG. 8 shown in the figure, the period following the broken line portion 801b is again displayed with a solid line. This means that if a QC check of the blood glucose measuring device is performed and it is determined that there is no abnormality, or if it is determined that there is an abnormality and an alternative blood glucose measuring device is available before the next scheduled QC inspection, blood glucose measurement is performed. It can be understood that it means either of the following.

  The blood glucose level graph display process in the embodiment has been described above.

  Next, according to the flowcharts of FIG. 9 and FIG. 10, the processing procedure of the application for realizing the blood glucose level registration in the patient's chart and the graph display processing by the CPU 301 of the information processing apparatus 200 of the embodiment described so far. explain.

  FIG. 9 is a flowchart illustrating the entire processing procedure of the application according to the embodiment.

  When the execution of this application is started by an instruction from the operator, the CPU 301 first searches the chart DB 304a for the chart information of the patient to be examined using the chart No., patient name, etc. as a key in accordance with the instruction from the operator. (Step S901). When the patient can be confirmed, the operator displays the processing menu and performs an operation of selecting one of them. This menu includes at least “read blood glucose measurement device data”, “display blood glucose level graph”, and “end”, and determine which of these has been selected in steps S902 to S904.

  First, when it is determined that “read data of blood glucose measurement device” is selected, the CPU 301 advances the process to step S905. In step S905, the CPU 301 waits for the proximity wireless communication unit 250 to be in a state where communication with the blood glucose measurement device 100 is possible, and when communication becomes possible, the device identification information 245 is sent to the blood glucose measurement device 100. , As well as request and receive measurement data 246. Then, the total blood glucose level in the received measurement data 246 is measured in the area 503 for storing the blood glucose level in the displayed patient chart, as measured by the blood glucose measurement device indicated by the received device identification information 245. Add and save in chronological order. When this storage process is completed, an erasure request for the measurement data 246 is transmitted to the blood glucose measurement device 100 to be erased in preparation for the next examination.

  On the other hand, when “Graph Display of Blood Glucose Level” is selected from the menu, the process proceeds from Step S903 to Step S906, and a display process of a graph (see FIG. 8) showing the transition of the blood glucose level is executed. Details of the processing in step S906 will be described later.

  Further, when “end” is selected in the menu (Yes in step S904), the present process is terminated. If a menu item other than “Read data of blood glucose measurement device”, “Graph display of blood glucose level”, “End” is selected (for example, graph display of other measurement data, etc.), the process proceeds to step S907. Perform the appropriate processing. Since the processing in step S907 is not directly related to the present invention, it will not be described in detail here.

  Next, details of step S906 will be described with reference to the flowchart of FIG.

  First, in step S1001, the CPU 301 displays an initial screen. This initial screen is easy to understand when it is considered that the areas 801 to 804 in FIG. 8 are blank. However, the blood glucose level for the most recent month may be displayed as the default designated period. In this case, in the area 802, the following processing may be performed by automatically inputting information in which the current day is the end of the period and the start date is one month before the area 802.

  In step S <b> 1002, the operator inputs a period during which the blood sugar level is displayed in area 802. In response to this, in step S1003, the CPU 301 reads the first blood glucose level data (measurement date and time, blood glucose level, device identification information) for the designated period from the area 503 in the patient's chart.

  Then, the CPU 301 advances the process to step S1004. When the process proceeds to step S1004, the CPU 301 searches the QC management DB 304b using the device identification information read in step S1003 as a key, and searches past QC inspection history information (in the area 602 in FIG. 6) of the corresponding blood glucose measurement device. Information). Then, from the acquired QC inspection history information, a QC inspection date that is before the “measurement date” read in step S1003 and is closest to the “measurement date” is searched, and the process proceeds to step S1005.

  In step S1005, the CPU 301 determines whether the “measurement date / time” is within one month from the “QC inspection date” found from the QC inspection history information (in other words, whether the QC procedure deadline has been exceeded). ).

  If it is within one month, the process proceeds to step S1006, and since the focused blood glucose level is sufficiently credible, the previous blood glucose level read out is drawn with a solid line. In steps S1006 and 1007, when the blood glucose level of interest is the first value in the designated period, there is no previous one, so no line segment is drawn. This is the same in step S1007 described below.

  On the other hand, if it is determined that it has exceeded one month, the process proceeds to step S1007, and since the credibility of the focused blood glucose level is suspicious, the blood glucose level read immediately before is indicated by a solid line. draw. If step S1007 has been executed even once, a process for displaying a message in the area 804 that alerts the user that QC inspection has expired is also performed.

  When the process of step S1006 or S1007 is completed, it is determined in step S1008 whether or not the line drawing for the total blood glucose level in the specified period has been completed. If not, the process from step S1003 is repeated, and if it is determined that the drawing of the whole blood glucose line segment for the specified period has ended, this process ends.

  As described above, according to the present embodiment, when displaying the result measured by the blood glucose measurement device, the blood glucose level measured from the previous QC check to the next scheduled QC check and the next QC check are displayed. By distinguishing and displaying the blood glucose level measured in a period exceeding the scheduled date, it becomes possible to perform correct diagnosis and diagnosis with emphasis on the former.

  Further, according to the embodiment, even when a blood glucose level graph is displayed retroactively several years ago, it can be determined whether or not there is a blood glucose level with low reliability (reliability). Therefore, it is possible to correctly grasp the past state of the patient.

  Furthermore, according to the embodiment, in a period from a certain day to the present, when a blood glucose level graph is displayed in a form different from the solid line, for example, a broken line, or the scheduled QC check date has been exceeded. , The effect of promoting the implementation can be expected.

  Furthermore, according to the embodiment, each blood glucose level and the device identification information of the blood glucose measuring device that measures the blood glucose level are stored and managed as a pair. Therefore, when going to a hospital every day and measuring using a blood glucose measuring device delivered from the hospital, dealing with the case of measuring the blood glucose level using one of an unspecified number of blood glucose measuring devices. Is possible.

  In the embodiment, the example in which the presence or absence of credibility is represented by a solid line or a broken line has been described. However, the line segment may be expressed by different colors or shades of the same color. The bending point of the broken line of the value may be represented by a mark of a different color. In some cases, the background along the time axis of the line graph may be represented by different colors.

  Further, in the embodiment, the graph display of the blood sugar level is shown by a line graph, but it is only necessary to show the blood sugar level along the time axis, so it is clear that the display form of the graph is not limited to the line graph.

  Furthermore, the various numerical values shown in the embodiment (for example, the QC inspection cycle is set to one month) are merely examples, and it is needless to say that these may be appropriately changed to be about two months.

  Furthermore, although non-contact communication prescribed | regulated to ISO / IEC 14443 was illustrated as communication between the blood glucose measurement apparatus 100 and the information processing apparatus 200 in embodiment, this is only an example and wired communication may be sufficient.

  Furthermore, in the embodiment, the example in which the medical record DB and the QC management DB are held in one information processing apparatus has been described. However, a device that holds the medical record DB and the QC management DB and a device that accesses the medical record DB and the QC management DB are connected via a network. May be connected. That is, the former is composed of a server and the latter is composed of a plurality of terminals. In the case of a relatively large medical institution, this form may be desired.

  Moreover, although the information processing apparatus in the embodiment requires hardware that communicates with the blood glucose measurement apparatus, most of the information processing apparatus can be realized by an application executed on the information processing apparatus. Therefore, it is obvious that the present invention includes a program for causing a computer to execute and a computer-readable storage medium storing the program.
