Abstract

A medication compliance, co-ordination and dispensing system for coordinating the administration of medication regimens at home equipped with a system for monitoring patient compliance and protection from overdosage and underdosage. The system is accessible to all types of patients, including children, the elderly, the visually-impaired, the hearing-impaired and patients with other handicaps. The device comprises a centrally positioned main housing containing a control element, a plurality of storage and dispensing units dedicated to different medications engageable with the main housing, and a system of input and output devices in communication with the control element. The I/O devices include visual and audible alarms for alerting the patient of administration times, voice and display means for providing extended medication information to the patient, a mini-camera for recording patient compliance and a user-wearable message receiving component for doing same. The compliance, co-ordination and dispensing system of the invention automatically dispenses medication according to a prescribed schedule but has built-in features which, in addition to recording non-compliance, allows inter alia adjustment of the medication criteria to protect against overdosage, as well as underdosage and preferably double-checks on the patient taking the dispensed medication and records and tracks when the medication is taken and co-ordinates this information with the medication regime programmed into the system.

compartment means dedicated to each receiver means and capable of containing medication received by said receiver means until said medication is removed by the patient; and

a plurality of first indicator means positioned on the outside of each secondary housing means, said indicator means actuable by the control element when real time equals said defined medication administration time for the said medication.

2. The medication compliance, co-ordination and dispensing system of claim 1, wherein said plurality of first indicator means is an illuminated bulb.

3. The medication compliance, co-ordination and dispensing system of claim 1, wherein said plurality of first indicator means is an audible alarm.

4. The medication compliance, co-ordination and dispensing system of claim 1, wherein said secondary housing means includes a front surface panel for embedding medication information in braille.

5. The medication compliance, co-ordination and dispensing system of claim 1, further comprising:

voice means located inside the main housing and actuable by the control element; and

speaker means for broadcasting output of said voice means.

6. The medication compliance, co-ordination and dispensing system of claim 5, wherein said voice means is actuable by the control element to selectively broadcast a predetermined message when real time equals said defined medication administration time.

7. The medication compliance, co-ordination and dispensing system of claim 1, wherein said compartment means includes:

a hinged trap door for accessing the dispensed medication contained in the compartment means; and

switch means associated with said hinged trap door and the control element such that when the trap door is opened the switch means is closed.

8. The medication compliance, co-ordination and dispensing system of claim 7, further comprising:

display means located on the outside surface of each secondary housing means, said display means actuable by the control element, wherein when said switch means is closed, the control element causes said display means to display a message.

9. The medication compliance, co-ordination and dispensing system of claim 1, further comprising:

a user-worn signal receiving device wherein the signal receiving device is activated when real time equals said defined medication administration time for a medication in the medication regimen.

10. The medication compliance, co-ordination and dispensing system of claim 9, further comprising:

signal transmission means associated with the control element for communicating with said signal receiving device.

11. The medication compliance, co-ordination and dispensing system of claim 9, wherein the user-worn signal receiving device includes:

display means for communicating medication information to the patient; and

vibrating means for alerting the patient at the defined medication administration time.

12. The medication compliance, co-ordination and dispensing system of claim 9, wherein the user-worn signal receiving device further includes sound means for alerting the patient at the defined medication administration time.

13. The medication compliance, co-ordination and dispensing system of claim 9, wherein the signal receiving device is a user-worn wristwatch.

14. The medication compliance, co-ordination and dispensing system of claim 13, wherein the user-worn wristwatch is programmable, said wristwatch including vibrator means, and wherein the wristwatch is programmed in conjunction with said prescription schedule such that when real time equals said defined administration time the vibrator means is activated.

15. The medication compliance, co-ordination and dispensing system of claim 13, wherein the user-worn wristwatch further includes sound means, and wherein the wristwatch is programmed in conjunction with the said prescription schedule such that when real time equals medication administration time, the sound means is activated.

16. The medication compliance, co-ordination and dispensing system of claim 7, further comprising:
