Abstract

A medication patch compliance control unit system and method is disclosed. The control unit can include an attachment sensor, a user interface and a controller that receives signals from the attachment sensor and sends signals to the user interface. The control unit can include an attachment sensor, a wireless transceiver and a controller that receives signals from the attachment sensor and sends signals through the transceiver. The attachment sensor can be a temperature sensor, and the controller can determine attachment based on whether the sensor is reading temperatures in the normal body temperature range. The user interface can include visual and/or audible indicators. The control unit can include an expiration timer, and provide an expiration signal when the patch is expired. The transceiver can transmit medication patch data to a healthcare provider. The controller can record when the medication patch is attached to and detached from the patient.

Claims

1. A medication compliance control unit for integration into a medication patch that includes an adhesive area for attachment of the patch to a patient and a medicated area containing medication for application to the patient, the medication compliance control unit comprising:

an attachment sensor detecting attachment of the medication patch to the patient;

a user interface communicating information to the patient; and

a controller receiving signals from the attachment sensor and sending signals to the user interface, at least some of the signals sent to the user interface being based on the received signals from the attachment sensor.

2. The medication compliance control unit of claim 1, wherein the attachment sensor is a temperature sensor;

and the controller determines attachment to the patient based on whether the temperature sensor is reading temperatures in the normal range of body temperatures.

3. The medication compliance control unit of claim 1, wherein the user interface includes a visual indicator controlled by the controller, the visual indicator displaying a first color when the attachment sensor detects attachment to the patient and displaying a second color when the attachment sensor no longer detects attachment to the patient.

4. The medication compliance control unit of claim 1, wherein the user interface includes an audible indicator controlled by the controller, the audible indicator transmitting a warning signal when the attachment sensor detects detachment of the medication patch from the patient.

5. The medication compliance control unit of claim 1, wherein the controller records when the medication patch is attached to the patient and when the medication patch is detached from the patient.

6. The medication compliance control unit of claim 5, further comprising a wireless transmitter controlled by the controller, wherein the controller transmits through the wireless transmitter in response to the medication patch being attached to the patient and in response to the medication patch being detached from the patient.

7. The medication compliance control unit of claim 1, further comprising a wireless transmitter controlled by the controller, wherein the controller transmits data pertaining to the medication patch through the wireless transmitter.

8. The medication compliance control unit of claim 7, wherein the controller transmits a notification signal through the wireless transmitter in response to the medication patch having not been worn for a predetermined period of time.

9. The medication compliance control unit of claim 1, further comprising an expiration timer, the controller providing an expiration signal through the user interface in response to the expiration timer indicating that the medication patch is expired.

10. A medication compliance control unit for integration into a medication patch that includes an adhesive area for attachment of the patch to a patient and a medicated area containing medication for application to the patient, the medication compliance control unit comprising:

an attachment sensor detecting attachment of the medication patch to the patient;

a wireless transceiver communicating data pertaining to the medication patch; and

a controller receiving signals from the attachment sensor and sending signals through the wireless transceiver.

11. The medication compliance control unit of claim 10, wherein the controller sends data to a healthcare provider through the wireless transceiver.

12. The medication compliance control unit of claim 11, wherein the attachment sensor also detects detachment of the medication patch from the patient;

and the controller sends attachment and detachment notifications through the wireless transceiver based on the signals from the attachment sensor.

13. A method of controlling a medication patch that includes a medication compliance control unit, the method comprising:

detecting attachment of the medication patch to a patient;

detecting detachment of the medication patch from the patient; and

signaling expiration of the medication patch.

14. The method of claim 13, wherein detecting attachment of the medication patch to the patient comprises sensing body temperature measurements using a temperature sensor.

15. The method of claim 14, wherein detecting attachment of the medication patch to the patient further comprises:

starting an expiration timer, and

recording an ON event.

16. The method of claim 15, wherein detecting detachment of the medication patch from the patient comprises the following steps after detecting attachment of the medication patch and prior to expiration of the medication patch:

sensing absence of body temperature measurements using the temperature sensor;

suspending the expiration timer,

recording an OFF event; and

signaling detachment of the medication patch through a user interface.

17. The method of claim 16, wherein signaling expiration of the medication patch comprises:

detecting when the expiration timer reaches an expiration value.

recording a time expired event; and

activating an expiration signal through the user interface.

18. The method of claim 16, further comprising:

detecting reattachment of the medication patch to the patient;

19. The method of claim 18, wherein detecting reattachment of the medication patch to the patient comprises the following steps after detecting detachment of the medication patch and prior to expiration of the medication patch:

sensing body temperature measurements again using the temperature sensor;

resuming the expiration timer,

recording an additional ON event; and

signaling attachment of the medication patch through the user interface.

20. The method of claim 13, further comprising indicating a previously expired medication patch by performing the following steps after signaling expiration of the medication patch:

sensing body temperature measurements using a temperature sensor; and

activating an expiration signal through a user interface.
