Description

  The present invention relates to a management system for a portable medical device for preventing non-portability of a portable medical device used in combination with a worn medical device worn on the skin such as an insulin pump, the worn medical device used in this system, and a portable device. The present invention relates to a management method of a medical device, and further, a portable medical device.

  In recent years, a treatment method in which a drug solution is continuously administered into a patient's body by subcutaneous injection or intravenous injection has been performed. For example, as a treatment method for diabetic patients, a treatment in which a minute amount of insulin is continuously administered into the patient's body is performed. In this treatment method, a portable insulin pump that is used by being attached to the skin of a patient is used to administer a drug solution (insulin) to the patient throughout the day.

  A user of such an insulin pump usually carries a blood glucose meter at all times, and performs an operation of adjusting the amount of insulin delivered from the insulin pump based on the measured blood glucose level. Therefore, in the following cited document 1, in order to perform this adjustment work, the glucose level (blood glucose level) measured by the glucose measurement module (blood glucose meter) is transmitted to the insulin pump by wireless communication at the infrared transmission port. Devices and methods have been proposed that can be used.

Special table 2007-503288 gazette

  However, the blood glucose meter is carried by the user of the insulin pump, but unlike the insulin pump, the blood glucose meter is carried without being worn on the patient's body. Therefore, if the user of the insulin pump forgets to leave the blood glucose meter at home and goes out, or forgets to leave the blood glucose meter at work and returns home, the blood glucose level cannot be measured, so the dosage of insulin can be adjusted. There is a risk of causing hypoglycemia or hyperglycemia.

  Therefore, an object of the present invention is to provide a management system for a portable medical device for preventing non-portability of a portable medical device used in a non-wearing manner in combination with a wearing medical device such as an insulin pump. It is another object of the present invention to provide a wearing medical device and a portable medical device used in the management system, and a method for managing the portable medical device.

  In order to achieve such an object, the portable medical device management system according to the present invention includes a wearing medical device to be worn on the skin for blood glucose level management, and a non-wearing device in combination with the wearing medical device. It is comprised by the portable medical device carried. The wearing medical device includes a wearing-side communication unit that performs wireless communication in a predetermined frequency band and receives a confirmation signal transmitted from the portable medical device, and a non-portable alarm that informs that the portable medical device is not portable. An output unit that outputs the information, and a wearing-side arithmetic unit that instructs the output unit to output the non-portable alarm when reception of the confirmation signal transmitted from the portable medical device is interrupted in the wearing-side communication unit It has. The portable medical device includes a portable communication unit that performs wireless communication with the wearing communication unit, and a portable side that instructs the portable communication unit to transmit the confirmation signal toward the wearing communication unit And an arithmetic unit.

  In the mobile medical device management system configured as described above, when the mobile medical device is out of the communication range of the wireless communication with the mounted medical device, a confirmation signal transmitted from the mobile medical device is transmitted to the mounted medical device. Cannot receive. For this reason, by setting the frequency band of these wireless communication so that the communication distance between the portable medical device and the attached medical device is limited to some extent, the portable medical device and the attached medical device are reduced to some extent. When separated by a limited distance, a non-portable alarm can be output from the output unit of the attached medical device. Thus, before the separation distance between the portable medical device and the attached medical device becomes large, it is possible to notify the wearer of the attached medical device that the portable medical device is not carried.

  As described above, according to the portable medical device management system of the present invention, when the portable medical device is separated from the worn medical device such as an insulin pump, the wearer of the worn medical device is prevented from carrying the portable medical device. Since notification can be made, it is possible to prevent non-portability of the portable medical device.

Here, a predetermined time is set after the inquiry signal Si is transmitted in step S4, and it is determined whether or not the confirmation signal Sc is received within that time. If it is determined that the confirmation signal Sc has been received (YES), the process proceeds to step S6. If it is determined that it has not been received (NO), the process proceeds to step S8.

[Step S6]
In step S6, the wearing-side computing unit 23 of the insulin pump 10 determines whether or not the blood glucose level measurement data dm received together with the confirmation signal Sc has been updated. If it is determined that it has been updated (YES), the process proceeds to the next step S7. If it is determined that it has not been updated (NO), the process directly returns to step S3.

In step S <b> 7, the blood glucose level measurement data dm received by the wearing-side communication unit 25 is stored in the storage unit 21 as the latest data according to an instruction from the wearing-side computing unit 23 of the insulin pump 10. Thereafter, the process returns to step S3.

[Step S8]
If it is determined in step S5 that the confirmation signal Sc from the paired blood glucose meter 100 has not been received by the wearing side communication unit 25 (NO), the process proceeds to step S8. In this step S8, it is determined whether or not the number of times that the confirmation signal Sc has not been continuously received has reached the predetermined nth time in the wearing-side computing unit 23 of the insulin pump 10. When it is determined that it is the nth time (YES), the process proceeds to the next step S9. If it is determined that it has not reached the nth time (NO), the process returns to step S3.

[Step S9]
In step S <b> 9, the wearing-side computing unit 23 of the insulin pump 10 instructs the output unit 27 to output a portable medical device non-portable alarm W. Thereby, the blood glucose meter 100 paired with the insulin pump 10 is out of the communication distance between the wearing side communication unit 25 and the portable side communication unit 115, and the blood glucose meter 100 is not portable to the user.

Notify that. This terminates the process.

[Step S26]
On the other hand, if it is determined in step S22 that wireless communication between the pump body 10a and the controller 10b has not been established (NO), the process proceeds to step S26. In this step S26, it is determined whether or not the number of times that the main body calculation unit 23a of the pump main body 10a determines that wireless communication is not continuously established (NO) has reached a predetermined mth time. If it is determined that this is the m-th time (YES), the process proceeds to the next step S27. If it is determined that the m-th time has not been reached (NO), the process directly returns to step S21.

[Step S27]
In step S27, steps S1 to S5 and steps S8 to S9 of FIG. 3 described in the first embodiment are performed between the pump main body 10a and the blood glucose meter 100 by the main body calculation unit 23a of the pump main body 10a. To do. Here, in step S5, when it is determined that the confirmation signal Sc from the portable communication unit 115 of the blood glucose meter 100 has been received by the main body communication unit 25a of the pump main body 10a (YES), step S6 and step S7 are performed. The management method of the procedure for directly returning from step S5 to step S3 is performed without storing the blood glucose level measurement data.
