  The storage unit 105 stores sound data, the scheduled number of measurements per day, a program, and the like. The control unit 104 includes a CPU and a memory, and the CPU functions as the control unit 104 by executing the program stored in the storage unit 105. The control unit 104 stores information indicating the type of instrument detected to be stored by the detection unit 102 when the switch 44 detects that the lid 18 is closed, and the same type of instrument. When a plurality of are detected, the number is also stored. That is, the number of detected chips 22 and puncture units 24 is also stored. The communication unit 106 communicates with the blood glucose meter 20 as necessary. The speaker 46 outputs a sound based on the detection result of the detection unit 102, for example, to notify the user that there is an instrument or the like that is not housed, thereby prompting attention.

  The blood glucose meter 20 includes a display unit 74, an operation unit 76, a speaker (notification unit) 80, a measurement unit 110, a control unit 112, a storage unit 113, and a communication unit 114.

  Next, operation | movement of the measurement system 10 of 1st Embodiment is demonstrated according to the flowchart shown in FIG.

  When detecting that the lid 18 is closed by the switch 44, the control unit 104 determines whether or not the blood glucose meter 20 is stored in the storage case 12 based on the on / off state of the switch 30 (step S1). .

  If it is determined in step S1 that the blood glucose meter 20 is stored, the process proceeds directly to step S3. If it is determined in step S1 that the blood glucose meter 20 is not stored in the storage case 12, the control unit 104 determines that the blood glucose meter 20 is stored. Is read out from the storage unit 105 and voice is output from the speaker 46 (step S2), and then the process proceeds to step S3.

  The user goes out with the storage case 12 so that the blood glucose level can be measured on the go. However, if the blood glucose meter 20 is not stored in the storage case 12, the user measures the blood glucose level on the go. I can't do it. Therefore, if the lid 18 is closed in a state where the blood glucose meter 20 is not stored in the storage case 12, the user is alerted by notifying that the blood glucose meter 20 is not stored.

  In step S <b> 3, the control unit 104 obtains the number of measurements per day (today) already measured from the blood glucose meter 20 via the communication unit 106. Next, the control unit 104 calculates a threshold value by subtracting the number of measurements acquired in step S3 from the scheduled number of measurements per day stored in the storage unit 105 (step S4). Note that when the blood glucose meter 20 is not stored in the storage case 12, the number of measurements cannot be acquired, and thus the threshold value is not calculated.

  Next, the control unit 104 determines whether or not the chip 22 is stored in the storage case 12 based on the on / off states of the switches 34a to 34e (step S5). If it is determined in step S5 that the chip 22 is not stored in the storage case 12, the control unit 104 notifies that the chip 22 is not stored, for example, voice data such as “chip is not stored”. After reading from the storage unit 105 and outputting sound from the speaker 46 (step S6), the process proceeds to step S9.

  When the chip 22 is not stored in the storage case 12, the blood sugar level cannot be measured when going out, so if the lid 18 is closed while the chip 22 is not stored in the storage case 12, the chip The user is alerted by notifying that 22 is not stored.

  On the other hand, when determining in step S5 that the chips 22 are stored in the storage case 12, the control unit 104 determines whether or not the number of chips 22 stored in the storage case 12 is equal to or greater than the threshold calculated in step S4. Is determined (step S7).

  If the number of chips 22 stored is greater than or equal to the threshold value in step S7, the process proceeds directly to step S9. If the number of chips 22 stored in the storage case 12 is smaller than the threshold value in step S7, the control unit 104 informs that there are not enough chips 22 stored, for example, reads out voice data from the storage unit 105 such as “there is little remaining chip” and outputs sound from the speaker 46 (step S8). Proceed to step S9. If the threshold value has not been calculated because the blood glucose meter 20 has not been stored, the process proceeds directly to step S9.

  A value (threshold value) obtained by subtracting the number of measurements today (today) already measured from the scheduled number of measurements for one day is the remaining number of measurements for today, and chips 22 corresponding to the threshold are not stored in the storage case 12 Cannot take measurements for today's remaining measurements on the go. Therefore, when the lid 18 is closed in a state where the number of chips 22 that are disposable instruments stored in the storage case 12 is less than the threshold, the user is alerted by notifying that the chips 22 are insufficient.

  In step S9, the control unit 104 determines whether or not the puncture unit 24 is stored in the storage case 12 based on the on / off states of the switches 38a to 38e. If it is determined in step S9 that the puncture unit 24 is not stored, the control unit 104 notifies that the puncture unit 24 is not stored, for example, voice data such as “the puncture unit is not stored”. After reading from the storage unit 105 and outputting sound from the speaker 46 (step S10), the process proceeds to step S13.

  When the puncture part 24 is not accommodated in the storage case 12, the skin cannot be punctured outside and the blood sugar level cannot be measured. Therefore, if the lid 18 is closed in a state where the puncture unit 24 is not stored in the storage case 12, the user is alerted by notifying that the puncture unit 24 is not stored.

  On the other hand, if it is determined in step S9 that the puncture unit 24 is stored in the storage case 12, the control unit 104 has the number of puncture units 24 stored in the storage case 12 equal to or greater than the threshold calculated in step S4. Whether or not (step S11).

  If the number of stored puncture units 24 is greater than or equal to the threshold value in step S11, the process proceeds directly to step S13. If the number of stored puncture units 24 is less than the threshold value in step S11, the control unit 104 After notifying that the stored puncture unit 24 is insufficient, for example, after reading out voice data such as “there is little remaining puncture unit” from the storage unit 105 and outputting voice from the speaker 46 (step S12), Proceed to step S13. If the threshold value has not been calculated because the blood glucose meter 20 has not been stored, the process proceeds directly to step S13.

  A value (threshold) obtained by subtracting the number of today's measurements that has already been measured from the scheduled number of measurements per day is the remaining number of measurements today, and when the puncture portion 24 for the threshold is not stored in the storage case 12, The remaining number of measurements today cannot be punctured and measured on the go. Therefore, if the lid 18 is closed in a state where the number of puncture units 24 that are disposable instruments stored in the storage case 12 is less than the threshold, the user is alerted by notifying that the chip 22 is insufficient. .

  In step S13, the control unit 104 determines whether the puncture instrument unit 26 is stored in the storage case 12 based on the on / off state of the switch 42. In step S13, the control unit 104 determines whether the puncture instrument unit 26 is stored. If the control unit 104 determines that it is not stored in the storage case 12, the control unit 104 notifies that the puncture instrument unit 26 is not stored in the storage case 12, for example, “the puncture instrument unit is not stored” or the like. The voice data is read from the storage unit 105 and the voice is notified from the speaker 46 (step S14).

  When the puncture instrument section 26 is not stored in the storage case 12, the skin cannot be punctured outside and the blood sugar level cannot be measured. Therefore, when the lid 18 is closed in a state where the puncture instrument section 26 is not stored in the storage case 12, the user is alerted by notifying that the puncture section 24 is not stored.

  Thus, in the first embodiment, whether or not the blood glucose meter 20, the plurality of chips 22, the plurality of puncture sections 24, and the puncture instrument section 26 are stored using the switches 30, 34, 38, and 42. If it is not stored, a notification to that effect is given, so that the user can recognize an unstored instrument and the like, prevent forgetting to store in the storage case 12, and go out. The blood sugar level can also be measured in advance.

  Further, when the number of chips 22 stored in the storage case 12 and the number of puncture portions 24 are smaller than the threshold value, a notification to that effect is made. The number of measurements can be performed. Moreover, since it alert | reports based on a detection result when the cover part 18 is closed, it can alert | report at an appropriate timing.

  In the first embodiment, the switch 30 is used to detect whether or not the blood glucose meter 20 is housed. However, the blood glucose meter 20 does not provide the switch 30 and sends an identification signal from the communication unit 114.

Alternatively, it can be performed using RFID (Radio Frequency Identification) or the like. Further, the communication units may be capable of transmitting and receiving information to and from each other by being in electrical contact with each other.

  Next, operation | movement of the measurement system 10 of 2nd Embodiment is demonstrated according to the flowchart shown in FIG.

  First, when the controller 104 detects that the lid 18 is closed by the switch 44, the controller 104 determines whether or not the blood glucose meter 20 is stored in the storage case 12 (step S21). Specifically, when the communication unit 120 receives the identification information of the blood glucose meter 20, the control unit 104 determines that the blood glucose meter 20 is stored in the storage case 12. At this time, the blood glucose meter 20 transmits the already measured number of measurements and the current date and time together with the identification information, and the communication unit 120 receives the identification information, the number of measurements today and the current date and time.

  If it is determined in step S21 that the blood glucose meter 20 is stored, the process proceeds directly to step S23. If it is determined in step S21 that the blood glucose meter 20 is not stored, the control unit 104 stores the blood glucose meter 20. For example, a sound indicating that the blood glucose meter is not stored is output from the speaker 46 (step S22), and the process proceeds to step S23.

  In step S23, the control unit 104 calculates a threshold value by subtracting the current number of measurements received in step S21 from the scheduled number of measurements per day. Note that when the blood glucose meter 20 is not stored in the storage case 12, the number of measurements cannot be acquired, and thus the threshold value is not calculated.

  Next, the control unit 104 determines whether the chip 22 is stored in the storage case 12 (step S24). Specifically, when any one of the communication units 122 a to 122 e receives the identification information of the chip 22, it is determined that the chip 22 is stored in the storage case 12. At this time, the chip 22 transmits the expiration date of the chip 22 together with the identification information, and the communication unit 122 receives the identification information and the expiration date.

  If it is determined in step S24 that the chip 22 is not stored in the storage case 12, the control unit 104 notifies that the chip 22 is not stored, for example, a sound such as “chip is not stored”. It outputs from the speaker 46 (step S25), and it progresses to step S30.

  On the other hand, if it is determined in step S24 that the chips 22 are stored in the storage case 12, the control unit 104 determines whether or not the number of chips 22 stored in the storage case 12 is equal to or greater than the threshold calculated in step S24. Is determined (step S26).

  If the number of chips 22 stored is greater than or equal to the threshold value in step S26, the process proceeds directly to step S28. If the number of chips 22 stored in the storage case 12 is smaller than the threshold value in step S26, the control unit 104 notifies that there are not enough chips 22 stored, for example, outputs a sound such as “there are few chips remaining” from the speaker 46 (step S27), and proceeds to step S28. The number of the communication units 122 that have received the identification information from the chip 22 is the number of the stored chips 22. If the threshold value is not calculated because the blood glucose meter 20 is not stored, the process proceeds to step S28.

  In step S28, the control unit 104 determines whether there is a chip 22 whose expiration date has passed based on the current date and time acquired in step S21 and the expiration date of the chip 22 acquired in step S24. To do.

  If there is no chip 22 whose expiration date has passed in step S28, the process directly proceeds to step S30. If there is a chip 22 whose expiration date has passed, the control unit 104 has a chip whose expiration date has passed. For example, a sound such as “a chip that has passed the expiration date is stored” is output from the speaker 46 (step S29), and the process proceeds to step S30. In addition, you may make it alert | report the place where the chip | tip 22 which has passed the expiration date is accommodated. That is, you may alert | report the position of the chip | tip fixing member 32 corresponding to the communication part 122 which received the expiration date older than the present date.

  In step S <b> 30, the control unit 104 determines whether the puncture unit 24 is stored in the storage case 12. Specifically, when any of the communication units 124 a to 124 e receives the identification information of the puncture unit 24, it is determined that the puncture unit 24 is stored in the storage case 12.

  If it is determined in step S30 that the puncture unit 24 is not accommodated, the control unit 104 notifies that the puncture unit 24 is not accommodated, for example, a sound such as “the puncture part is not accommodated” from the speaker. 46 (step S31), the process proceeds to step S34.

  On the other hand, if it is determined in step S30 that the puncture unit 24 is stored, the control unit 104 determines whether or not the number of puncture units 24 stored in the storage case 12 is equal to or greater than the threshold calculated in step S24. Judgment is made (step S32).

  If the number of puncture units 24 stored in step S32 is equal to or greater than the threshold value, the process proceeds to step S34, and if the number of puncture units 24 stored in the storage case 12 is smaller than the threshold value in step S32, The control unit 104 notifies that the number of stored puncture units 24 is insufficient, for example, outputs a sound such as “there is little remaining puncture unit” from the speaker 46 (step S33), and proceeds to step S34. move on. The number of communication units 124 that have received the identification information from the puncture unit 24 is the number of puncture units 24 accommodated. If the threshold value has not been calculated because the blood glucose meter 20 has not been stored, the process proceeds directly to step S34.

  In step S34, the control unit 104 determines whether or not the puncture instrument unit 26 is stored in the storage case 12. Specifically, when the communication unit 126 receives the identification information of the puncture device unit 26, it is determined that the puncture device unit 26 is stored in the storage case 12. If it is determined in step S34 that the puncture instrument part 26 is not accommodated, the control unit 104 notifies that the puncture instrument part 26 is not accommodated, for example, “the puncture instrument part is not accommodated. "Is notified from the speaker 46 (step S35).

  As described above, in the second embodiment, in addition to the effects obtained in the first embodiment, the storage case 12 receives the expiration date from the chip 22, respectively. In some cases, this can be notified, and the user can be prevented from going out by storing the chip 22 that has expired.
