Abstract

Described are methods and systems to train a user in the proper operation of a manual patch pump to ensure that the user can attach the patch pump to a suitable location on the skin of the user and actuate the pump correctly in accordance with a prescribed dosing schedule or a self-calculated dosing schedule.

Claims

1. A patch type drug delivery pump training system comprising:

a trainer device including;

a base configured to be attached to a user'"'"'s epidermis;

a housing attached to the base, the housing having dosing actuator;

a processor coupled to a memory, clock and dosing switches connected to the dosing actuators, the dosing switches configured to indicate dosing events whenever the dosing actuators have been actuated and such dosing events stored in the memory; and

a monitor device disposed apart from the trainer device, the monitor device being configured to receive data from the memory of the trainer device, the data including dosing events and time of each event so that the monitor device provides an indication of whether the user has actuated the dosing switches in accordance with a dosing plan stored in one of the monitor device or the trainer device.

2. The system of claim 1, in which the monitor device comprises a smartphone programmed to receive data transmitted by the trainer device by a suitable wireless protocol.

3. The system of claim 2, in which the wireless protocol is selected from one of a Bluetooth, WiFi, RFID, or a Near-Field-communication protocol.

4. The system of claim 1, in which the trainer device further comprises a power source connected to the processor of the trainer device.

5. The system of claim 1, in which the trainer further comprises:

an audio output connected to the processor to provide the indication in audible form;

a visual output connected to the processor to provide the indication in visual form; and

a wireless transmitter connected to the processor to transmit the data to the monitor device.

6. The system of claim 1, in which the base further comprises at least one sensor configured to determine a suitable location for a drug delivery pump based on the impedance of the epidermis at which the housing is attached thereto.

7. The system of claim 6, in which the sensor comprises at least two electrodes configured to contact the epidermis and transmit an alternating signal between the at least two electrodes.

8. The system of claim 6, in which the sensor comprises at least two electrodes configured to measure capacitance of the epidermis at a location of attachment of the trainer device.

9. A method of training a user on the use of an actual patch type drug delivery pump configured to deliver a drug stored in the pump body, the method comprising the steps of:

providing a dosing schedule of the drug to the user;

providing a trainer device to the user, the device having a dummy housing and dummy actuators similar in shape and size as the actual patch type drug delivery pump, the dummy housing containing a processor and memory coupled to respective switches of the dummy actuators;

furnishing the user with a dosing schedule;

actuating the dummy actuators;

recording activation of the switches for the simulated actuators and the time at which such activation occurred into the memory to provide a record of training dosage events; and

outputting the record to provide for a comparison between training usages of the trainer device as compared to the dosing schedule.

10. The method of claim 9, further comprising:

comparing a time at which actuating of the simulated actuators is taking place and the time prescribed by the dosing schedule;

in the event at which the time prescribed in the dosing schedule is not within a predetermined time period of the actuating step, recording noncompliance of the dosing schedule in the memory;

or

in the event at which the prescribed time for dosing is within a predetermined time period of the actuating step, recording a compliance with the dosing schedule in the memory.

11. The method of claim 10, in which the recording of an error comprises annunciating a negative feedback to the user at the time the recording is made.

12. The method of claim 9, in which the recording of the compliance comprises annunciating of a positive feedback to the user at the time the recording is made.

13. The method of claim 9, in which the outputting comprises displaying a graphical representation of time at which one or more actuations have occurred and the prescribed dose at the prescribed time.

14. A method of training a user on the use of an actual patch type drug delivery pump configured to deliver a drug stored in the pump body, the method comprising the steps of:

providing a dosing schedule of the drug to the user;

providing a trainer device to the user, the device having a simulated housing and simulated actuators similar in shape and size as the actual patch type drug delivery pump, the simulated housing containing a processor and memory coupled to respective switches of the simulated actuators;

annunciating to the user the dosing schedule;

recording activation of the switches for the simulated actuators and the time at which such activation occurred into the memory to provide a record of training dosage events;

and outputting the record to provide for a comparison between training usages of the trainer device as compared to the dosing schedule.

15. The method of claim 14, in which the predetermined time period comprises any time period from about 10 minutes to about 60 minutes.

16. The method of claim 14, in which the steps of recording and outputting are completed within one hour.

17. The method of claim 14, in which the steps of recording and outputting are completed within 45 minutes.

18. The method of claim 14, in which the steps of recording and outputting are completed within 30 minutes.

19. The method of claim 14, in which the steps of annunciating, recording and outputting are completed within one hour.

20. The method of claim 14, in which the steps of annunciating, recording and outputting are completed within 45 minutes.

21. The method of claim 14, in which the steps of annunciating, recording and outputting are completed within 30 minutes.
