Abstract

The general purpose of the device described herein, the Smart Automatic Medication Dispenser, is to aid medical patients who must consume several types of medications several times a day for long periods of time. Often, due to daily diversions, it can be difficult for a patient to keep a running record of the amount of medications and the times at which they must be administered. The specific purpose of this computer controlled dispenser device is to provide a convenient vehicle and means by which properly proportioned medication doses are housed and automatically delivered to the patient in single complete doses. This user friendly and expandable dispenser will deliver medication in the proper chronological order and at the precisely correct/prescribed daily time intervals for a nominal period of one full week. Included in this device are comprehensive patient alerting capabilities, including familiar voices, all coordinated with medication delivery. Contained within the dispenser device is the ability to dial out and receive telephone messages to inform health care personnel of the dispenser'"'"'s status, usage and to change internal dispenser programs.

Claims

1. A programmable automatic medication dispenser, comprising:

a dispenser main body having a receiving bin;

a medication magazine, detachable from the dispenser main body, having a plurality of stacks, each stack having a plurality of stacked medication canisters, and said detachable medication magazine capable of holding a multi-day, prescribed sequence of medications, as a single transportable unit;

a patient alerting means attached to the dispenser main body;

a plurality of ejection arms;

a computing means that monitors the time of the day, generates a signal to the patient-alerting means at programmed dosage times, and determines a selected medication ejection arm and a selected medication canister;

a patient activated medication release button generating an electrical ejection signal;

a means to translate the electrical ejection signal into a mechanical motion and activate the selected ejection arm to push the selected medication canister from the medication magazine into the receiving bin, whereby, at predetermined dosing times, the selected medication canister is delivered to the patient from the detachable medication magazine.

2. The programmable automatic medication dispenser of claim 1 wherein the means to translate the electrical ejection signal into the mechanical motion is a solenoid.

3. The programmable automatic medication dispenser of claim 1 further comprising a simple front panel comprising:

a single flashing patent activated push button;

a small visual liquid crystal display window showing the time of day;

an LED malfunction light.

4. The programmable automatic medication dispenser of claim 1 wherein the detachable medication magazine further comprises a means to hold liquid and tablet medications.

5. The programmable automatic medication dispenser of claim 1 further comprising a position sensor switch and a means to alert the patient by voice message if the collection bin is not properly positioned to receive the selected medication canister.

6. The programmable automatic medication dispenser of claim 1 further comprising a means for independent ejection for out of sequence delivery of the medication canisters from within the detachable medication magazine.

7. The programmable automatic medication dispenser of claim 1 further comprising

a means to detect regiment compliance;

and

a means to record the deviations of regiment compliance.

8. The programmable automatic medication dispenser of claim 7 wherein the means to detect regiment compliance is a optical sensor.

9. The programmable automatic medication dispenser of claim 1 wherein the computing means further comprises:

a means to connect to a remote computer; and

a means to transfer information to and from a home-based programmable automatic medication dispenser and the remote computer.

10. The programmable automatic medication dispenser of claim 9 further comprising a means to automatically notify the remote computer after a set number of missed doses has occurred.

11. The programmable automatic medication dispenser of claim 9 wherein the remote computer and the home-based computer further comprise a means to remotely change the programming and medication regiment of the home-based programmable automatic medication dispenser.

12. The programmable automatic medication dispenser of claim 9 wherein the medication magazine further comprises a built-in electronic identification circuitry to communicate with the embedded central computer to identify itself and the patient as well as relay information on daily dosage times regarding the medication contained within the magazine.

13. The programmable automatic medication dispenser of claim 1 further comprising a means to remotely monitor the programmable automatic medication dispenser and patient usage of the dispenser.

14. The programmable automatic medication dispenser of claim 13 wherein the means to remotely monitor the patient of the dispenser is a video camera.

15. The programmable automatic medication dispenser of claim 1 further comprises a fault tolerant means to monitor and correct faulty dispenser behavior in the presence of a single fault and perform a safe shut down of the unit in the presence of multiple faults.

16. The programmable automatic medication dispenser of claim 15 wherein the fault tolerant means comprises a watchdog timer.

17. The programmable automatic medication dispenser of claim 15 further comprising a means to detect any dispenser malfunctions and enable a warning indicator light.

18. The programmable automatic medication dispenser of claim 1 further comprising a means to persistently alert the patient of medication time and said persistent alerting means being capable of remote location from the dispenser main body.

19. The programmable automatic medication dispenser of claim 18 wherein a signal to the means to persistently alert the patient of medication time is a Radio Frequency signal.

20. The programmable automatic medication dispenser of claim 18 wherein the persistent alerting means is an acoustic alerting means.

21. The programmable automatic medication dispenser of claim 18 wherein the persistent alerting means is an optical signal.

22. The programmable automatic medication dispenser of claim 18 wherein the persistent alerting means is a message printed out on a playing TV.

23. The programmable automatic medication dispenser of claim 18 further comprising a means to terminate the alarms if the patient does not activate the patient activated medication release button within a preset time interval and a means to reset the dispenser to the next sequence of medications.

24. The programmable automatic medication dispenser of claim 1 further comprising a means to give step by step voice directions saying that it is time to take the medication and leading patients through a delivery sequence.
