≪Outline of drug administration support method≫
FIG. 3 is a flowchart illustrating an outline of a chemical solution administration support method according to the embodiment. The chemical solution administration support method shown in this flowchart is an outline of a procedure for prompting a change in administration parameter setting related to drug administration performed by the pump body 10 as necessary. It is executed by a program constituting the control unit 101. Hereinafter, first, an outline of the chemical solution administration support process will be described along the procedure of the flowchart of FIG.

[Step S1]
In step S <b> 1 immediately after the start of the medicinal solution administration support process, the input / output control unit 101 performs a process of reading administration-related data [D] from the storage unit 103. The administration-related data [D] read out here is data that affects the administration of insulin, and is, for example, the total dose [Q] or the additional dose [Qadd] of insulin. The administration-related data [D] may be personal data such as the patient's weight [W], blood glucose level [G], or activity amount [M], which is input from the operation unit 20a.

  Of these, the total dose [Q] is the total daily dose of insulin for the patient, and is the total insulin dose of the basal dose [Qb] and the additional dose [Qadd]. The basal dose [Qb] is a daily dose administered continuously based on a basal dose profile set by a doctor. On the other hand, the additional dose [Qadd] is the total amount of insulin administered by additional administration to the patient per day, and is a value that varies depending on the meal content and exercise amount of the patient who administers insulin by the drug solution administration device 1. It is. Therefore, the total dose [Q] including the additional dose [Qadd] is also a value that constantly varies. The total dose [Q] and the additional dose [Qadd] of these insulins are values that are automatically stored in the storage unit 103 following the execution of the drug solution administration.

  Personal data such as patient weight [W], blood glucose level [G], or activity level [M] is a value that fluctuates following changes in the patient's lifestyle, and is related to the dose of insulin. It is data. Among these, the blood glucose level [G] may be an average blood glucose level calculated based on, for example, the pre-meal blood glucose level used for calculating the additional dose at the time of additional administration. These values (personal data) are values measured by an external measuring device and input from the operation unit 20a. Input to the operation unit 20a from an external measurement device may be performed via wired or wireless communication.

[Step S2]
In step S2, the input / output control unit 101 determines whether or not there is a predetermined change in the administration related data [D] read in step S1. If it is determined that there is a change (YES), the process proceeds to step S3. If it is determined that there is no change (NO), the process returns to step S1.

[Step S3]
In step S3, the input / output control unit 101 instructs the display unit 20b to issue a warning. In response to an instruction from the input / output control unit 101, the display unit 20b displays a warning indicating that there is a predetermined change in the administration related data [D].

  This motivates the patient using the drug solution administration device 1 to notify the doctor in charge that there is a predetermined change in the administration related data [D]. Changes in dosing parameters can be prompted.

  When a warning is issued in step S3, the input / output control unit 101 causes the calculation unit 102 to automatically calculate some of the administration parameters from the amount of change in the administration related data [D]. Also good. In this case, the input / output control unit 101 updates the administration parameter stored in the storage unit 103 with the administration parameter automatically calculated by the calculation unit 102.

[Step S4]
Thereafter, in step S4, the input / output control unit 101 performs a process for changing the setting of the administration parameter relating to insulin administration, and ends the example process. The administration parameters whose settings are changed here are the administration profile and basal dose [Qb] in basal administration, and the total dose [Q] including the basal dose [Qb]. The administration parameters include an insulin effect value [E] and a carbohydrate / insulin ratio [C] calculated using the total dose [Q]. The insulin effect value [E] can be calculated from the total dose [Q] based on the 1700 rule, 1800 rule, and the like. The carbohydrate / insulin ratio [C] can be calculated from the total dose [Q] based on 300 rules, 400 rules, 500 rules and the like. Furthermore, the administration parameters whose settings are changed include a target blood glucose level [Gt] for calculating a single additional dose in the additional administration of insulin, and a remaining insulin time [T]. The insulin effect value [E] and the carbohydrate / insulin ratio [C] are also values used for calculating one additional dose. Here, the setting of at least one of the administration parameters as described above is changed.

<< Medical Solution Administration Support Method According to First Embodiment >>
FIG. 4 is a flowchart (part 1) showing a detailed procedure of the drug solution administration support method according to the first embodiment, and shows a first stage of the drug solution administration support process. FIG. 5 is a flowchart (part 2) showing a detailed procedure of the chemical solution administration support method according to the first embodiment, and shows a second stage of the chemical solution administration support process following the flowchart of FIG. The chemical solution administration support methods shown in these flowcharts are the details of the procedure shown in the flowchart of FIG. 3, and values automatically stored in the storage unit 103 of the remote controller 20 (for example, total dose [Q]). Is a procedure for using as administration-related data [D].

  Note that steps S101 to S106 in FIG. 4 correspond to step S1 in FIG. 3, steps S201 to S203 in FIG. 4 correspond to step S2 in FIG. 3, and steps S401 to S403 in FIG. 5 correspond to step S4 in FIG. It corresponds. Hereinafter, an example of a detailed procedure of the drug administration support method executed by the program constituting the input / output control unit 101 will be described along the procedure shown in the flowcharts of FIGS. 4 and 5.

[Step S101]
First, in step S <b> 101, the input / output control unit 101 performs a process of setting the storage days N of administration related data to 1. The storage days N of the administration-related data is the number of days that have elapsed since the administration parameter was set, and is initialized to the storage days N = 1 when the administration parameter is set.

[Step S102]
In step S102, the input / output control unit 101 determines whether the time managed by the date and time management unit 104 is a fixed time (YES) or not (NO). Although the set time for the fixed time is not limited, for example, it is set to 8:00 am. If it is determined that the time is fixed (YES), the process proceeds to step S103.

[Step S103]
In step S <b> 103, the input / output control unit 101 counts the total daily dose [Q] of insulin administered on the previous day and stores it in the storage unit 103. Here, the input / output control unit 101 reads from the storage unit 103 all of the basal dose [Qb] and the additional dose in the additional administration for the previous day. Then, the calculation unit 102 is caused to calculate the sum of the read basal dose [Qb] and the additional dose [Qadd] obtained by summing up the daily dose, and the calculated value is set as the total dose [Q]. The data is stored in the storage unit 103.

[Step S104]
In step S <b> 104, the input / output control unit 101 performs processing for setting the storage days N to N + 1.

[Step S105]
Thereafter, in step S105, the input / output control unit 101 determines whether N is a predetermined number of days. The predetermined number of days is not limited, but is set to about 30 days, for example. If N is determined to be the predetermined number of days (YES), the process proceeds to the next step S106. On the other hand, if it is determined that N is not the predetermined number of days (NO), the process returns to step S102 and the subsequent steps are repeated.

[Step S106]
In step S <b> 106, the input / output control unit 101 reads out the total dose [Q] for a predetermined storage period N days from the storage unit 103.

[Step S201]
Next, in step S201, the input / output control unit 101 instructs the calculation unit 102 to calculate the average value [Qav] of the total dose [Q]. Here, the calculation unit 102 calculates an average value [Qav] of the total dose [Q] for the storage days N days read from the storage unit 103 in step S102.

[Step S202]
Thereafter, in step S202, the input / output control unit 101 reads from the storage unit 103 an average value [Qav0] of the total dose [Q] when the administration parameters are set. This average value [Qav0] is stored in the storage unit 103 as an initial value of the total dose [Q], which is the administration-related data [D], when an administration parameter is set last time according to an instruction from the input / output control unit 101 Suppose that it is done.

[Step S203]
Next, in step S203, the input / output control unit 101 determines the average value [Qav] of the total dose [Q] calculated in step S201 and the average value of the total dose [Q] when the previous administration parameters were set. A difference [Qav−Qav0] from [Qav0] is calculated, and it is determined whether or not the absolute value [| Qav−Qav0 |] of the difference exceeds the threshold [TH]. Here, the threshold value [TH] is input from the operation unit 20 a in advance and stored in the storage unit 103. Note that the average value [Qav] of the total dose [Q] calculated in step S201 is increased or decreased by a predetermined ratio or more than the average value [Qav0] of the total dose [Q] when the administration parameters were set last time. It may be determined whether or not.

  If it is determined that the value has exceeded (YES), it is determined that there is a predetermined change in the value of the total dose [Q], and the process proceeds to step S3. On the other hand, if it is determined that it has not exceeded (NO), the process returns to step S101 and the subsequent steps are repeated.

[Step S3]
In step S3, the input / output control unit 101 instructs the display unit 20b to issue a warning. In response to an instruction from the input / output control unit 101, the display unit 20b displays, as a warning, a content prompting the change of the administration parameter regarding insulin administration, and ends the first stage of the procedure of the medical solution administration support process.

  When a warning is issued in step S3, the input / output control unit 101 instructs the calculation unit 102 based on the average value [Qav] of the total dose [Q], the basal dose [Qb], and the insulin effect. The value [E] and the carbohydrate / insulin ratio [C] may be calculated. In this case, the input / output control unit 101 updates these administration parameters stored in the storage unit 103 with these administration parameters automatically calculated by the calculation unit 102.

  As described above, the patient using the drug solution administration device 1 can know that there has been a considerable change in the total dose [Q], and the doctor in charge needs to change the administration parameters for insulin administration. Motivation to confirm whether or not there is can be obtained.

[Step S401]
In step S401, the input / output control unit 101 determines whether an input for changing the administration parameter has been made from the operation unit 20a. Here, the administration parameters whose settings are directly changed by the input from the operation unit 20a include the administration profile and the basal administration dose [Qb] in the basal administration among the administration parameters described above, and further the basal administration dose [Qb]. At least one of the total dose [Q], the target blood glucose level [Gt], and the remaining insulin time [T].

  When at least one of these administration parameters is changed by an input from the operation unit 20a, the input / output control unit 101 determines that a change has been input (YES) and proceeds to the next step S402. On the other hand, if it is determined that no change has been input (NO), the second stage of the procedure of the chemical solution administration support process is terminated.

  Thus, even when a warning that prompts the user to change the administration parameter is displayed on the display unit 20b, if the doctor determines that the administration parameter does not need to be changed, the administration parameter is changed. It is possible to finish the process.

  In addition, this step S401 may be a process after the number of days has elapsed since the warning was issued to the display unit 20b in step S3. In this case, taking into account the number of days that have passed since the warning was issued, the doctor may change the setting of the administration parameter based on the administration-related data measured immediately before step S401.

[Step S402]
In step S402, the input / output control unit 101 performs a process of rewriting and changing the administration parameter stored in the storage unit 103 to the value input from the operation unit 20a.

  At this time, if the changed administration parameter is the administration profile and the basal dose [Qb] in the basal administration, the input / output control unit 101 receives other values based on these values input to the computing unit 102. Instruct the calculation of dosing parameters. Thereby, the operation unit 102 calculates the total dose [Q] including the basal dose [Qb]. Further, the calculation unit 102 uses the calculated total dose [Q] to calculate an insulin effect value [E] and a carbohydrate / insulin ratio for calculating a single dose (additional dose) in additional administration of insulin. [C] is calculated.

  In addition, the input / output control unit 101 performs a process of rewriting and changing the administration parameters stored in the storage unit 103 with these values calculated by the calculation unit 102.

  In addition, the structure which the control part of the terminal device 30 like the personal computer which a doctor owns implements the above steps S401 and S402 may be sufficient. In this case, the setting of the administration parameter is changed in the terminal device 30, whereby the calculation unit in the terminal device 30 calculates the other administration parameters described above. Then, the administration parameter is transmitted from the communication unit in the terminal device 30 to the communication unit 20 c of the remote controller 20, and the administration parameter stored in the storage unit 103 of the remote controller 20 is transmitted from the terminal device 30. Implement the procedure for rewriting and changing parameters.

[Step S403]
In step S403, the input / output control unit 101 calculates the average value [Qav0] of the total dose [Q] stored in the storage unit 103 as the average value [Qav] of the total dose [Q] calculated in step S201. Rewrite to Thereby, the average value [Qav0] of the total dose [Q] at the time of setting the administration parameter is updated, and the second stage of the procedure of the chemical solution administration support process is ended.

[Step S201 ′]
Step S201 ′ is a step after the input / output control unit 101 reads the total dose [Q] for the number of storage days N from the storage unit 103 in step S106. In step S201 ′, the input / output control unit 101 reads from the storage unit 103 the average value [Qav0] of the total dose [Q] when the administration parameters are set.

[Step S202 ′]
Thereafter, in step S202 ′, the input / output control unit 101 out of the total dose [Q] for the storage days N days exceeds the threshold value [TH] with the average value [Qav0] read in step S201 ′. It is determined whether the number of days [Nup] exceeds a predetermined number of days [THd]. At this time, the input / output control unit 101 instructs the calculation unit 102 to calculate a difference [Q−Qav0] from the average value [Qav0] with respect to each total dose [Q] for N days of storage. . Then, it is determined whether the absolute value [| Q−Qav0 |] of the difference exceeds the threshold value [TH], the number of days exceeding the threshold value [TH] is counted, and the counted number of days [Nup] is Then, it is determined whether or not the predetermined number of days [THd] is exceeded. Here, it is assumed that the predetermined number of days [THd] serving as a determination criterion is input in advance from the operation unit 20 a and stored in the storage unit 103.

  If it is determined that the value has exceeded (YES), it is determined that there is a predetermined change in the value of the total dose [Q], and the process proceeds to step S3. On the other hand, if it is determined that it has not exceeded (NO), the process returns to step S101 and the subsequent steps are repeated.

[Step S403 ′]
Step S403 ′ is a step after performing the process of rewriting and changing the administration parameter stored in the storage unit 103 to a value input from the operation unit 20a, and further to a value calculated from this value in Step S402. It is. In step S403 ′, the input / output control unit 101 causes the calculation unit 102 to calculate the average value [Qav] of the total dose [Q] for the storage days N days. This average value [Qav] is calculated using the total dose [Q] for the storage days N days read out in step S202 ′.

[Step S404 ′]
Thereafter, in step S404 ′, the input / output control unit 101 calculates the average value [Qav0] of the total dose [Q] stored in the storage unit 103 as the average value of the total dose [Q] calculated in step S403 ′. Rewrite to [Qav]. Thereby, the average value [Qav0] of the total dose [Q] at the time of setting the administration parameter is updated, and the second stage of the procedure of the chemical solution administration support process is ended.

<< Medium Solution Administration Support Method According to Third Embodiment >>

Therefore, only step S103 'will be described below, and redundant description will be omitted.

[Step S103 ′]
Step S103 ′ is a step after it is determined in step S102 that the time managed by the date management unit 104 is fixed (YES). In step 103 ′, the input / output control unit 101 stores the weight [W] input from the operation unit 20 a in the storage unit 103 until 24 hours before it is determined to be regular. Thereby, the medical solution administration support using the patient weight [W] as the administration related data [D] is performed.

  This third embodiment can be combined with the second embodiment. In this case, step S103 in the flowchart of FIG. 6 is replaced with step S103 ′, the total dose [Q] in the flowcharts of FIGS. 6 and 7 is read as body weight [W], and the initial value of the administration-related data [D] is used.
