Abstract

The present invention is a new electronic memory-assist device which can be used to remind an individual when it is time to take a prescribed medicine. The invention uses complementary metal-oxide semiconductor technology in conjunction with surface-mounted device technology to provide a programmable portable unit. The device has three parts: a body-carried reminder, a local interactive compliance processor and a supervisory unit. The reminder has a portable power supply, microprocessors, software, memory, an alarm, an input key and communication linkage to the compliance processor. The compliance processor has a central processing unit, a pill case, a modem and, possibly, a recharger for the portable power supply. The supervisory unit is connected to the central processing unit remotely by modems. The device operates by providing data to the user through an alarm that it is time to take prescribed medication. The alarm is visual, auditory, tactile or any combination of the three. The alarm is initiated by software controlling microprocessors in the body-carried reminder and the pill case. The alarm is generated by comparison between the current time and times residing in the prescription database. The alarm continues until interrupted by either a request for more time prior to compliance or through reception of a message signifying that medication has been taken. All compliance data is stored in the central processing unit of the compliance processor.

Claims

1. A medication supervisory reminder apparatus comprising a body-carried reminder having a microprocessor array, an alarm connected to the array, software and memory connected to the array, a portable communications transmitter and receiver connected to the array, and a control key connected to the alarm, a local interactive compliance processor having a fixed communications transmitter communicating with the portable transmitter and receiver on the body-carried reminder, the local interactive compliance processor having a central processing unit, a memory and a timer connected to the processor, and a pill case connected to the processor for communicating an alarm to the body-carried reminder when the pill case is not opened on schedule, further comprising a remote supervisory unit and modems connected to the local interactive compliance processor and to the supervisory unit for communicating non compliance to the supervisory unit by modems.

2. The apparatus of claim 1, further comprising a communications link on the supervisory unit for communicating with the portable receiver on the body-carried reminder for transferring medication regimes from the supervisory unit to the body-carried reminder.

3. The apparatus of claim 2, wherein the local compliance processor has a receiver-transmitter for receiving and transmitting communications of a medication regime from and to the body-carried reminder and for receiving alarm delay requests from the body-carried reminder.

4. A medication supervisory reminder apparatus comprising a body carried remainder having a receiver and transmitter for communicating with a local interactive compliance processor, having a central processing unit, a modem and a pill case connected to the processor for communicating an alarm to the body carried remainder when the pill case is not opened on schedule, a remote supervisory unit having a modem connectable to the local interactive compliance processor modem, for receiving non-compliance messages from the local interactive compliance processor.

5. The apparatus of claim 4, a microprocessor array, an alarm, software, memory, and an input key connected to the array for requesting an alarm delay from the compliance processor.

6. The apparatus of claim 5, wherein the alarm further comprises an auditory alarm, a tactile alarm or a visual display.

7. The apparatus of claim 5, wherein the body-carried reminder is wrist-worn.

8. The apparatus of claim 5, wherein the body-carried reminder is pendant-worn.

9. The apparatus of claim 5, wherein the body-carried reminder and the local interactive compliance processor communicate by radio frequency.

10. The apparatus of claim 5, wherein the body-carried reminder and the local interactive compliance processor are connected by infrared linkage.

11. The apparatus of claim 5, wherein the microprocessor array of the body-carried reminder is programmed with a database containing the medical history of a patient, a patient'"'"'s prescription regimen and a patient'"'"'s response to a reminder.

12. The apparatus of claim 5, wherein the local interactive compliance processor further comprises a recharger connectable to the body-carried reminder.

13. A method of communicating medication compliance information comprising programming a body-carried reminder with prescription regime information, initiating an alarm in the body-carried reminder by generating a first signal when actual time corresponds to programmed medication delivery time, alarming a user of the portable reminder through a visual display and the alarm, which are triggered by the first signal, maintaining and transmitting user prescription regimen information, user compliance information and user physiologic information from the body-carried reminder to a central processing unit in a local interactive compliance processor, and storing the data in the central processing unit of the local interactive compliance processor, connecting a remote supervisory unit thru modems to the local interactive compliance processor and communicating non compliance to the supervisory unit.

14. The method of claim 13, further comprising reprogramming the body-carried reminder by a response signal generated by a remote pill case.

15. The method of claim 13, further comprising signalling a medication alarm from the compliance processor to the body-carried reminder.

16. The method of claim 14, further comprising responding to the alarm, the alarm and the visual display is by pressing a delay input key positioned on the body-carried reminder.

17. The method of claim 14, further comprising responding to the alarm, the alarm and the visual display is by opening a pill case connected to the compliance processor and removing medication.

18. The method of claim 13, further comprising delivering a noncompliance message from the central processing unit to a remote supervisory unit.
