Description

Terminal device, terminal device control method, program, and drug solution administration system

The present disclosure relates to a terminal device, a method for controlling the terminal device, a program, and a drug solution administration system.

BACKGROUND ART Conventionally, a drug solution administration device having a pen-like shape for administering a drug solution into a patient's living body is known. As such a liquid drug administration device, for example, an insulin pen that administers insulin into a living body using a syringe needle is known.

Additionally, each time a dispensing operation is performed, administration-related data (date and time of dispensing operation, dispensed amount, etc.) is automatically recorded in the main unit, and the recorded administration-related data can be sent to an information processing device such as a smartphone. Insulin pens called smart insulin pens are known. The use of a smart insulin pen allows patients to record insulin administration related data. Medical professionals such as doctors and nurses can refer to the administration-related data recorded by the smart insulin pen to check records regarding insulin administration to patients.

On the other hand, when administering insulin using an insulin pen, the user needs to perform priming immediately before administering insulin. Dry injection refers to an operation in which a flow channel of a drug solution such as a syringe needle is filled with a drug solution, and at the same time, a blockage caused by a foreign object mixed in the flow channel is removed. Insulin pens apply pressure to a medicinal solution stored in a reservoir using a pusher to push the medicinal solution toward the tip of the injection needle and deliver it into the living body. However, when using the insulin pen for the first time, when changing the needle, or when a certain period of time has passed since administering the drug, the flow path from the reservoir that stores the drug to the tip of the needle is not filled with chemical solution. There may be cases where foreign objects or air bubbles are mixed into the flow path of the insulin pen. If pressure is applied to the drug solution in the reservoir in this state, the insulin pen will not be able to deliver the desired amount of drug solution, so the user must perform a blank shot immediately before administering insulin. be.

In order for the administration-related data of the smart insulin pen to accurately indicate the actual dose of the drug solution to the patient, it is necessary to distinguish between a dispensing operation for the purpose of blank injection and a dispensing operation for the purpose of injection. Patent Documents 1 and 2 describe techniques related to recording administration-related data using a smart insulin pen.

It is determined whether the operation is for the purpose of injecting the drug solution M (injection operation). In the present embodiment, the terminal device 10 holds the default value of the blank injection setting definition in advance, but when the administration-related data is acquired from a new liquid drug administration device 20, or at a timing desired by the user, the terminal device 10 Accepts corrections to blank firing setting definitions from . Hereinafter, as an example, the operation when the user operates the terminal device 10 to read administration-related data from the drug solution administration device 20 will be described. The following process may be executed after a login operation using patient P's identification information or the like.

In step S1 in FIG. 6, the control unit 11 determines whether communication, such as Bluetooth (registered trademark) communication, has been established with the drug solution administration device 20 (insulin pen). If communication is established (YES in step S1), the control unit 11 proceeds to step S2, and if not (NO in step S1), it continues the processing in step S1 and waits.

In step S2, the control unit 11 acquires device-related data from the liquid drug administration device 20. The device-related data includes a device ID (identification information, such as a serial number) that identifies the liquid drug administration device 20. When the control unit 11 receives such device-related data from the liquid drug administration device 20, the control unit 11 stores it in the storage unit 12.

In step S3, the control unit 11 receives and acquires administration-related data from the drug solution administration device 20. The administration-related data includes administration-related information for each ejection operation indicating the number of units of ejection operation, date and time, and the like. If a plurality of ejection operations have been performed on the liquid medicine administration device 20 before receiving the administration-related data, the control unit 11 receives a plurality of pieces of administration-related information regarding the plurality of ejection operations from the liquid medicine administration device 20. When the control unit 11 receives such administration-related data from the liquid drug administration device 20, the control unit 11 causes the storage unit 12 to store the data.

In step S4, the control unit 11 determines whether or not there has been communication in the past with the drug solution administration device 20 (insulin pen) specified by the device-related data acquired in step S2. Specifically, the control unit 11 may store in the storage unit 12 the device IDs of the liquid drug administration devices 20 with which it has communicated in the past. Then, if the device ID included in the device-related data of the liquid drug administration device 20 acquired in step S2 is included in the device ID stored in the storage unit 12, the control unit 11 controls It may be determined that the user has communicated with the user. The control unit 11 compares the latest date and time of communication with the drug solution administration device 20 in the past with the oldest date and time of the device-related information acquired in step S3, and determines that the former is older than the latter. You can evaluate the consistency of date and time by checking that. If the control unit 11 has communicated with the liquid medicine administration device 20 specified by the device-related data in the past (YES in step S4), the process proceeds to step S21 of FIG. 8, and if not (NO in step S4), the process proceeds to step S21. The process advances to step S11 in FIG.

In step S11 of FIG. 7, the control unit 11 accepts a selection of a blank shot setting definition from the user. Specifically, the control unit 11 may cause the display unit of the output unit 15 to display a screen for accepting a blank shot setting definition setting from the user, including a range of unit numbers.

FIG. 9 shows an example of a screen 50 displayed on the display section, which is the output section 15 of the terminal device 10, for accepting a selection of a blank firing setting definition from the user. Screen 50 includes input areas 51-53 and images 54-56.

The input area 51 is an area for inputting the "data recording interval". The input area 52 is an area for inputting the lower limit of the "unit number range". The input area 53 is an area for inputting the upper limit of the "unit number range". "Data recording interval" means that when a second ejection operation is performed on the liquid drug administration device 20 after a first ejection operation, the first and second ejection operations are performed in a series for drug liquid administration. This is a time interval that is a fixed period of time that serves as a reference for determining whether or not an operation has been performed. The "unit number range" is the range of the number of units (discharge amount) in which a discharge operation performed on the liquid drug administration device 20 is determined to be a blank discharge operation.

FIG. 10 shows an example of possible input ranges and default values for the data recording interval and unit number range. The control unit 11 may display a default value (5 minutes) of the "data recording interval" in the input area 51, and allow a numerical value to be selected within the inputtable range (0 to 15). The control unit 11 displays the lower limit default value (0.50 units) of the “unit number range” in the input area 52, and selects a numerical value within the inputtable range (0.50 to 4.50). It may be possible to do so. The control unit 11 displays the upper limit default value (2.00 units) of the "unit number range" in the input area 53, and allows a numerical value to be selected within the inputtable range (1.00 to 5.00). It's okay. For example, in response to the input areas 51 to 53 being selected by the user, the control unit 11 may display a screen for selecting a numerical value on the display unit of the output unit 15 and accept the input of the numerical value.

When the “end” image 54 is selected, the control unit 11 finishes accepting the selection of the blank firing setting definition, and displays the screen that was being displayed before displaying the screen 50 on the display unit of the output unit 15. You may. When the “save” image 55 is selected, the control unit 11 may cause the storage unit 12 to store the numerical values input in the input areas 51 to 53 as blank firing setting definitions. When the "reset" image 56 is selected, the control unit 11 may return the values input in the input areas 51 to 53 to default values. The control unit 11 may skip step S11 and use the default value of the blank firing setting definition. Even if the user does not select the blank firing setting definition, the default value may be used.

The control unit 11 may display values other than the default values of the "data recording interval" and "unit number range" illustrated in FIG. 10 as initial values in the input areas 51 to 53. For example, the control unit 11 registers in advance in the terminal device 10 or the cloud 30 the initial value of the blank setting definition for each latest drug solution administration device 20 or drug name used by the user, and the control unit 11 A value determined by the striking setting definition may be displayed as the initial value. When the "reset" image 56 is selected, the control unit 11 may return the values input to the input areas 51 to 53 to these values.

In step S12, the control unit 11 classifies the administration-related data into a blank injection operation or an injection operation based on the blank injection setting definition selected by the user in step S11. Specifically, the control unit 11 determines whether the ejection operation indicated by the administration-related information is an empty ejection operation for each piece of administration-related information included in the administration-related data acquired in step S3 of FIG. 6, based on the empty ejection setting definition. It is determined whether or not it is a hitting operation.

For example, the control unit 11 determines that the temporal interval between the first and second administration-related information that is continuous in time is within the "data recording interval," and the number of units of the first administration-related information is " If the amount falls within the range of ``unit number range'', the ejection operation related to the first administration-related information may be determined to be a blank ejection operation. The control unit 11 may determine that the last ejection operation among the plurality of ejection operations indicated by the administration-related information included in the administration-related data is not a blank operation. The control unit 11 may determine that the ejection operation determined not to be a blank ejection operation is an injection operation (ejection operation for the purpose of administering the drug solution M).

For example, an example of determination when the control unit 11 receives administration-related data including the following four pieces of administration-related information from the liquid drug administration device 20 will be described.

Discharge operation 1: 11:00:27 1.00 units Discharge operation 2: 11:14:30 0.50 units Discharge operation 3: 11:14:34 1.50 units Discharge operation 4: 12:50 13 seconds 1.00 unit
For example, the dates of the four administration-related information are the same. Further, for example, in the blank firing setting definition, the "data recording interval" is set to within 15 minutes, and the "unit number range" is set to 0.50 to 2.00 units. In this case, the control unit 11 determines the discharge operations 1 to 4 as follows. That is, ejection operation 1 is not the last ejection operation among ejection operations 1 to 4, and the time interval between ejection operations 1 and 2 (14 minutes and 3 seconds) is within the "data recording interval" (15 minutes), In addition, the number of units for discharge operation 1 (1.00 units) is included in the "unit number range" (0.50 to 2.00 units). Therefore, the control unit 11 determines the discharge operation 1 to be a blank firing operation. Discharge operation 2 is not the last discharge operation among discharge operations 1 to 4, and the time interval (4 seconds) between discharge operations 2 and 3 is within the "data recording interval" (15 minutes), and The number of units of 2 (0.50 units) is included in the "unit number range" (0.50 to 2.00 units). Therefore, the control unit 11 determines the discharge operation 2 to be a blank firing operation. Discharge operation 3 is not the last discharge operation among discharge operations 1 to 4, and the number of units of discharge operation 3 (1.50 units) is included in the "unit number range" (0.50 to 2.00 units). However, the time interval between ejection operations 3 and 4 (1 hour, 35 minutes, 39 seconds) exceeds the "data recording interval" (15 minutes). Therefore, the control unit 11 determines the ejection operation 3 to be an injection operation. Discharge operation 4 is the last discharge operation among discharge operations 1 to 4. Therefore, the control unit 11 determines the ejection operation 4 to be an injection operation.

In this way, the control unit 11 determines whether the ejection operation is a blank firing operation based not only on the time interval of the ejection operation but also on the number of units of ejection operation. Therefore, according to the terminal device 10, it is possible to acquire administration-related data that more accurately reflects the actual dose of the medical solution M. Further, the control unit 11 receives a selection of a blank firing setting definition including a range of units and a temporal upper limit (data recording interval) from the user, and performs blank firing based on the blank firing setting definition selected by the user. Determine whether it is an operation. Therefore, the user can appropriately set the blank firing setting definition according to the usage status of the liquid drug administration device 20 and the like. The control unit 11 determines whether the number of units of the ejecting operation is equal to the number of units indicated by the blank firing setting definition, regardless of the time interval between the ejecting operations or whether it is the last ejecting operation of a plurality of ejecting operations. If it is within the range, the ejection operation may be determined to be a blank firing operation.

In step S13, the control unit 11 calculates statistics regarding the ejection operation determined to be a blank firing operation in step S12. For example, the control unit 11 may calculate the number of blank firings per day, the number of blank firing units per day, etc. as statistics regarding the ejection operation. The number of blank discharges per day is the average value per day of the number of discharge operations that are determined to be blank discharge operations during a certain data acquisition period (statistical period). The number of units of blank firing per day is the average value per day of the amount of discharged material discharged by a discharge operation that is determined to be a blank firing operation during the data acquisition period. For example, the control unit 11 may calculate values such as the median value, variance, or standard deviation as other statistics regarding the quantitative information on the number of times of blank firing and the number of units of blank firing.

In step S14, the control unit 11 displays the statistics calculated in step S13, the drug name (not set), and the administration-related data classified as a blank shot operation or an injection operation in step S12 on the display unit of the output unit 15.

FIG. 11 shows an example of a screen 60 displayed on the display unit of the output unit 15 when the terminal device 10 receives administration-related data including 10 pieces of administration-related information from the drug solution administration device 20. In the screen 60, an image 61 of "Register only the latest item" is selected by the user when registering the latest administration-related information out of the 10 pieces of administration-related information. An image 62 of "Register all" is selected by the user when registering all 10 pieces of administration-related information. An image 63 of "Cancel" is selected by the user when canceling the registration of administration-related information.

12 to 14 are examples of the screen 70, the screen 80, and the screen 90 that the control unit 11 displays on the display unit of the output unit 15 when the “all registration” image 62 is selected on the screen 60. It shows. For example, the control unit 11 may display the screens 70, 80, and 90 side by side within the same window, display the screens 70, 80, and 90 in a selectable manner in a plurality of windows, or may be displayed in a switchable manner using tabs.

The screen 80 in FIG. 12 displays the statistics calculated in step S13. The screen 80 displays the following information: "Number of blank firings/day (times)", "Number of blank firing units/day (U)", "Statistical period (days)", "Data recording interval (minutes)", "Unit number range upper limit ( The items ``U)'' and ``lower limit of unit number range (U)'' are displayed for ``last time of transmission'' and ``this time.'' "Number of blank shots/day (times)" is the number of blank shots per day. "Number of blank firing units/day (U)" is the number of blank firing units per day. “Statistics period (days)” is the data acquisition period during which the statistics were calculated. When the control unit 11 calculates other statistics, it may display them together. "Data recording interval (minutes)," "upper limit of unit number range (U)," and "lower limit of unit number range (U)" indicate the contents of the blank firing setting definition used to determine blank firing. . “Last time of transmission” indicates information about administration-related data acquired from the liquid drug administration device 20 last time. “This time” indicates information about administration-related data acquired from the liquid drug administration device 20 this time. The flowchart in FIG. 7 shows the process executed when administration-related data is acquired for the first time from the drug solution administration device 20 (NO in step S4 in FIG. 6). Therefore, in step S14, the control unit 11 may display each item in the "Last time of transmission" column as blank, or may omit display of the "Last time of transmission" column. Further, if there is a history of communication with a liquid medicine administration device other than the liquid medicine administration device 20 specified by the device-related data acquired this time, the control unit 11 uses the administration-related data of the liquid medicine administration device different from the liquid medicine administration device 20. After clearly indicating that there is, information on administration-related data from the most recently communicated liquid drug administration device may be displayed.

The control unit 11 selectably displays images 81 to 86 in the column of the "change panel" to display the "data recording interval (minutes)," "upper limit of unit number range (U)," and "lower limit of unit number range." (U)'' is accepted from the user. Images 81 and 82 are images that accept an increase or decrease in the value of "data recording interval (minutes)." Images 83 and 84 are images that accept an increase or decrease in the value of "unit number range upper limit (U)." Images 85 and 86 are images that accept an increase or decrease in the value of the "unit number range lower limit (U)." The control unit 11 changes the display of the value of the blank firing setting definition on the screen 80 according to the selection of these images 81 to 86. In response to the change in the value of the blank firing setting definition, the control unit 11 determines whether the blank firing operation is performed for each ejection operation indicated by the administration-related data, similarly to step S12. Based on the determination result, the control unit 11 calculates the statistics of the blank firing operation in the same manner as in step S13, and updates the current value of the statistics in the screen 80 based on the calculation results. In this way, the control unit 11 changes the blank firing setting definition according to the selection of images 81 to 86, and in conjunction with this, updates the display of the statistics of the discharge operation determined to be a blank firing operation. do. In other words, the control unit 11 calculates a first statistic regarding the blank firing operation based on the determination result of the blank firing operation performed using a certain blank firing setting definition, and causes the display unit of the output unit 15 to display the first statistic. After that, if the blank firing setting definition is modified, the blank firing operation is determined again based on the blank firing setting definition, the second statistic regarding the blank firing operation is calculated based on the determination result, and the second statistic is calculated. The first statistic is updated based on the amount and displayed on the display unit. Therefore, the user can adjust the blank firing setting definition while checking the statistics, and can improve the accuracy of the blank firing operation determination. If administration-related data is acquired for the second time or later, the statistics of the previous administration-related data are also displayed, so the user can compare the statistics of the administration-related data acquired this time and compare the statistics of the administration-related data acquired this time. The validity of statistical values of administration-related data can be confirmed.

A screen 90 in FIG. 13 shows a time-series change in the number of units of ejection operations determined to be empty firing operations or injection operations, using a sample graph showing ejection operations. In the screen 90 , a display area 91 displays the date and time range of the discharge operation displayed within the screen 90 . In the example of FIG. 13, data from 11:00 on Tuesday, August 2, 2022 is displayed. The display area 92 displays a sample graph showing a time-series change in the number of units of ejection operation. In the example of FIG. 13, the horizontal axis shows time, and the vertical axis shows the number of units. Images 93 (93a, 93b, 93c, 93d) show samples of data of the ejection operation. Images 93a, 93b, 93c, and 93d show data of the aforementioned ejection operations 1 to 4. In this way, the control unit 11 displays a time-series change in the number of units of ejection operation as a sample graph showing the ejection operation based on the number of units of ejection operation and the date and time indicated by the administration-related information. Therefore, the user can easily recognize what kind of discharge operation has been performed. In addition, in the example of FIG. 13, the control unit 11 displays images 93a and 93b showing the ejection operations 1 and 2 determined to be empty injection operations in triangles, and images 93a and 93b indicating the ejection operations 3 and 4 determined to be injection operations. 93c and 93d are shown as circles. In this way, the control unit 11 may indicate a sample of a dispensing operation determined to be a blank firing operation and a sample of a dispensing operation determined to be an injection operation using different symbols. In other words, the control unit 11 creates a first symbol indicating a discharging operation that has been determined to be a blank firing operation, and a second symbol that is different from the first symbol and indicating a discharging operation that has not been determined to be a blank firing operation. A graph including the following may be displayed on the display section of the output section 15. Therefore, the user can easily recognize whether each sample of the ejection operation is determined to be a blank ejection operation or an injection operation. In the example of FIG. 13, the graph showing the time-series change in the number of units of ejection operation is a scatter diagram, but the graph is not limited to a scatter diagram, and may be another graph such as a line graph or a bar graph.

A straight line 95 indicates the "unit number range upper limit (U)" included in the blank firing setting definition. A straight line 96 indicates the "lower limit (U) of the unit number range" included in the blank firing setting definition. In this way, since the control unit 11 displays the unit number range together with the graph showing the time-series change in the number of units of the ejection operation, the user can easily see the relationship between the number of units of each ejection operation and the unit number range. It is possible to recognize the

Image 97 shows a scroll bar for selecting, by scrolling, the time range in which the graph is displayed in the display area 92. Image 98 shows a scroll bar for selecting, by scrolling, the range of the number of units in which the graph is displayed in the display area 92. Image 99 shows a button for enlarging or reducing the display in the unit number axis direction (vertical axis) by a selection operation. Image 100 shows a button for enlarging or reducing the display in the time axis direction (horizontal axis) by a selection operation. The control unit 11 switches the time range and the range of the number of units of the graph displayed in the display area 92 in response to the user operating these images 97 to 100. This allows the user to easily select the range of the graph to be displayed on the display unit of the output unit 15.

For example, when a pointer that can be operated by the pointing device of the input unit 14 exists in the display area 92, the control unit 11 controls the area around the pointer in response to operation of a scroll wheel or the like provided on the pointing device. The graph display may be enlarged or reduced. Alternatively, in response to an area within the display area 92 being selected by, for example, a drag operation using a pointing device, the control unit 11 may enlarge and display the area. Further, for example, when an operation including pinching in, pinching out, or dragging is performed on the touch screen, the control unit 11 switches the range of samples of the ejection operation displayed in the display area 92 accordingly. It's okay.

In FIG. 14, a screen 70 displays a list of determination results as to whether or not the ejection operation is a blank ejection operation for each of the drug name (unset) and the administration-related information included in the administration-related data. .

The input area 71 is an area for inputting the name of the drug. The process of the flowchart in FIG. 7 is executed when it is the first time that administration-related information has been received from the drug solution administration device 20 (NO in step S4 in FIG. 6). Therefore, the drug name in the input area 71 is not set. The user inputs the drug name in the input area 71. The input area 71 may display multiple drug names in a drop-down list or the like and accept the selection of one of the drug names. When the drug name is entered in the input area 71, the control unit 11 may display the drug name selected by the user in the input area 71, for example, as shown in FIG. 15.

The display area 72 is an area that displays a list of determination results as to whether or not the ejection operation is a blank ejection operation for each piece of administration-related information included in the administration-related data. In the example of FIG. 14, the display area 72 displays a list of the date and time of the ejection operation, the number of units, and the determination result of blank firing in a table format. In the example of FIG. 14, the control unit 11 indicates a determination of injection by a check box 73 without a check mark, and a determination of a blank injection by a check box 74 with a check mark. When the checkboxes 73 and 74 are selected by the user, the control unit 11 may switch between displaying checkmarks and displaying them. In this manner, the control unit 11 may accept corrections from the user regarding the determination results regarding blank firing for each of the ejection operations listed on the display unit of the output unit 15.

If the operator of the drug solution administration device 20 and the user of the terminal device 10 are different, the user of the terminal device 10 does not directly confirm the use of the drug solution administration device 20. Therefore, if the operator of the drug solution administration device 20 and the user of the terminal device 10 are different, the control unit 11 may not accept selections from the check boxes 73 and 74 by the user. For example, the control unit 11 obtains the identification information of the operator of the liquid medicine administration device 20 and the identification information of the user of the terminal device 10, compares the two, and if they are different, the operator of the liquid medicine administration device 20 and the identification information of the user of the terminal device 10 are obtained. It may be determined that the user of the device 10 is different. Alternatively, for example, when the terminal device 10 is used by logging in with the account of the medical worker D, the control unit 11 may not accept selections from the check boxes 73 and 74 by the user.

The "cancel" image 75 is selected by the user when canceling the administration-related data registration operation. The "data import" image 76 is selected by the user when registering the drug name and administration-related data classified as blank injection or injection.

When the number of ejection operations determined to be empty ejection operations among a plurality of ejection operations performed on the liquid drug administration device 20 within a certain period of time deviates from a predetermined number range, An alert may be notified. For example, the terminal device 10 determines that the number of ejection operations performed on the liquid drug administration device 20 that are determined to be blanks within a certain period (for example, one month) exceeds a predetermined number of times, or , a screen indicating an alert may be displayed on the display section of the output section 15. Further, the control unit 11 may notify the cloud 30 of an alert. Furthermore, when an alert occurs, the control unit 11 may notify the user of the possibility that there is an error in the blank firing setting definition.

Further, when any of the images 83 to 86 included in the screen 80 in FIG. 12 is selected and the unit number range of the blank firing setting definition is changed, the control unit 11 causes the screen 90 in FIG. The display of the included straight lines 95 and 96 may be modified. Further, when any of the images 81 to 86 included in the screen 80 in FIG. 12 is selected and the blank firing setting definition is changed, the control unit 11 performs the following based on the changed blank firing definition, as in step S12. A blank discharge operation is determined for each ejection operation indicated by the administration-related data. The control unit 11 displays an image 93 (93a) of each sample of the ejection operation included in the display area 92 of the screen 90 in FIG. -93d) and the display of the check boxes 73 and 74 in FIG. 14 may be updated. In this way, the control unit 11 changes the blank firing setting definition by selecting the images 81 to 86 included in the screen 80, and when the determination result of the blank firing operation changes, in conjunction with this, the control unit 11 changes the blank firing setting definition by selecting the images 81 to 86 included in the screen 80. You may update the display. According to such a configuration, the user can see how the determination of a blank firing operation changes due to an operation that changes the unit number range of the blank firing setting definition, for example, in various display formats such as the screens 70 to 90. It is possible to confirm by

Further, the control unit 11 allows the user to change the unit number range by displaying straight lines 95 and 96 indicating the unit number range of the blank firing setting definition so that the user can select and move them up and down on the screen 90. You may accept it. According to such a configuration, the user can change the unit number range by an intuitive operation of moving the straight lines 95 and 96. In addition, the control unit 11 changes the unit number range by moving the straight lines 95 and 96 in the same way as when images 81 to 86 are selected, and in conjunction with this, changes the unit number range upper limit ( You may update the values of "U)" and "lower limit of unit number range (U)." The control unit 11 may determine whether or not each discharge operation is a blank firing operation based on the changed unit number range. The control unit 11 displays an image 93 (93a) of each sample of the ejection operation included in the display area 92 of the screen 90 in FIG. -93d) and the display of the check boxes 73 and 74 in FIG. 14 may be updated. Further, the control unit 11 may calculate the statistics of the blank firing operation in the same manner as in step S13 in response to the determination of the blank firing operation, and may update the value of the statistics in the screen 80 based on the calculation result. In this way, by displaying the blank firing setting definition, the blank firing operation determination result, the blank firing operation statistics, etc. displayed on the plurality of screens 70, 80, and 90 in conjunction with each other, the user can It is possible to confirm these relationships using various display formats.

In step S15, the control unit 11 determines whether the administration-related data including the drug name and the determination result of the blank injection operation or injection operation has been modified by the user. Here, the modification of the administration-related data may include updating the determination result based on the modification of the blank shot setting definition. If the drug name and administration-related data have been corrected (YES in step S15), the control unit 11 returns to step S13, and otherwise proceeds to step S16 (NO in step S15).

In step S16, the control unit 11 determines whether the user has instructed to import the administration-related data. Specifically, for example, the control unit 11 may determine that an instruction has been given to import administration-related data when the "data import" image 76 in FIG. 14 is selected. If the user instructs the control unit 11 to import administration-related data (YES in step S16), the process proceeds to step S17; otherwise (NO in step S16), the control unit 11 continues the process in step S15 and inputs the drug name. , the blank firing setting definition, and the determination results of the blank firing operation or injection operation, etc., will continue to be accepted.

In step S17, the control unit 11 determines whether a drug name has been selected by the user. Specifically, for example, if a drug name is input in the input area 71 of FIG. 14, the control unit 11 may determine that the drug name is selected. If the drug name is selected (YES in step S17), the control unit 11 proceeds to step S19, and otherwise proceeds to step S18 (NO in step S17).

In step S18, the control unit 11 displays an alert to select the drug name on the display unit of the output unit 15. FIG. 16 shows an example of a screen 120 showing an alert to select a drug name. The screen 120 prompts the user to select a drug name by displaying "No drug name has been selected." After completing the process in step S18, the control unit 11 returns to step S15. For example, when the "close" image 121 is selected by the user, the control unit 11 may erase the display on the screen 120, finish the process of step S18, and return to step S15.
