Abstract

An electronic pillbox includes a plurality of compartments for storing different medications, an LCD-based user interface for interacting with a user, and a software-programmable electronic computer for controlling the administration functions of the pillbox. The pillbox may also include a battery and one or more types of alarms. Using the user interface, a user can schedule a multiple drug therapy by inputting sleeping pattern data and a dosage amount for a particular compartment. The computer automatically calculates the dosage schedule based on this information, and automatically recalculates the schedule if this information is altered by the user. A visual indicator on the user interface is illuminated when a particular medication is to be taken, and at the same time an audible and/or mechanical alarm may be activated. The combination of the visual and audible or mechanical alarms ensures that the correct medication is administered according to the programmed schedule.

Claims

1. A portable electronic pillbox, comprising:

a plurality of medication compartments;

a user-interface for displaying information to a user of the pillbox and for receiving information from the user, the user information including a start time and a stop time indicating the sleeping pattern of the user, and a dosage amount for each medication in the plurality of medication compartments; and

an electronic computer for automatically calculating a dosage schedule for each medication compartment based upon the sleeping pattern of the user and the dosage amount for the particular medication.

2. The portable electronic pillbox of claim 1, further comprising:

a power source including a main battery for supplying power to the pillbox, and a backup battery for supplying a limited amount of power to the pillbox when the main battery fails.

3. The portable electronic pillbox of claim 1, further comprising:

a plurality of visual alarm indicators.

4. The portable electronic pillbox of claim 3, wherein each compartment has an associated visual alarm indicator.

5. The portable electronic pillbox of claim 1, further comprising:

an audible alarm indicator.

6. The portable electronic pillbox of claim 5, wherein the audible alarm indicator generates a distinct sound for each compartment.

7. The portable electronic pillbox of claim 1, further comprising:

a mechanical alarm indicator.

8. The portable electronic pillbox of claim 1, wherein each medication compartment includes a separate lid.

9. The portable electronic pillbox of claim 1, wherein the pillbox is made of transparent plastic.

10. The portable electronic pillbox of claim 1, wherein the user interface includes an LCD for displaying information to the user, and a plurality of user interface buttons.

11. The portable electronic pillbox of claim 10, wherein the LCD display includes a numeric timer, a plurality of visual alarm indicators, and a plurality of navigational messages.

12. The portable electronic pillbox of claim 11, wherein the LCD display includes a visual alarm indicator for each compartment.

13. The portable electronic pillbox of claim 10, wherein the LCD display further includes a low battery indicator.

14. The portable electronic pillbox of claim 10, wherein the plurality of user interface buttons include at least 2 buttons for controlling the operation of the electronic computer.

15. The portable electronic pillbox of claim 14, wherein the plurality of user interface buttons are used to input the user information regarding the dosage amount for each medication and the user'"'"'s sleeping pattern.

16. The portable electronic pillbox of claim 10, wherein the electronic computer is programmed to operate in a plurality of different functional modes.

17. The portable electronic pillbox of claim 16, wherein one of the user interface buttons is for switching the pillbox between the plurality of different functional modes.

18. The portable electronic pillbox of claim 16, wherein the plurality of modes include a normal mode, a set clock mode, a daily dosage mode, and an alarm mode.

19. The portable electronic pillbox of claim 1, wherein the electronic computer automatically recalculates the dosage schedules for each medication compartment if the user alters the information regarding the user'"'"'s sleeping pattern.

20. A portable electronic pillbox, comprising:

a plurality of medication compartments;

a visual alarm indicator for each compartment; and

an electronic computer for automatically calculating a dosage schedule for each medication compartment based upon information entered into the computer by a user of the pillbox, including the user'"'"'s sleeping pattern and the dosage amount for the medication, and for enabling the appropriate visual alarm indicator when a particular medication is scheduled for delivery.

21. A compact electronic pillbox, comprising:

a plastic housing partitioned into a plurality of compartments, each compartment having a separate lid;

an electronic user interface and control device located at the center of the plastic housing, including an LCD, a plurality of user input buttons, a microcomputer, and a battery; and

a control program executed by the electronic user interface and control device for receiving data indicating the sleeping pattern of a user of the pillbox and the dosage amount for each compartment, and for calculating a dosage schedule for each compartment based on the sleeping pattern of the user and the dosage amount for the particular compartment.

22. A portable electronic pillbox, comprising:

means for storing a plurality of medications;

means for displaying information to a user of the pillbox regarding a medication schedule, and for receiving information from the user, including information regarding the sleeping pattern of the user and the dosage amount for each of the medications contained in the means for storing; and

means for calculating the medication schedule for each of the medications contained in the means for storing based on the information from the user regarding the dosage amount for each medication and the user'"'"'s sleeping pattern.

23. The portable electronic pillbox of claim 22, comprising:

means for automatically recalculating the medication schedule based on a change in the user information.

24. A portable electronic pillbox, comprising:

a plurality of medication compartments;

a visual alarm indicator for each compartment;

a mechanical or audible alarm; and

a microcomputer for scheduling dosage times for each medication compartment based upon a user'"'"'s sleeping pattern and a dosage amount for each medication, and for enabling the visual and mechanical or audible alarms when a particular medication is scheduled for administration.

25. A method of scheduling dosage times for a multiple-drug therapy, comprising the steps of:

providing a portable electronic pillbox having a plurality of medication compartments, a visual indicator for each compartment, and an electronic computer coupled to the visual indicators;

inputting user information to the electronic computer, including a start time and a stop time that define the user'"'"'s sleeping pattern, and a dosage amount for each drug contained within the plurality of medication compartments;

calculating a dosage schedule for each drug based upon the user'"'"'s sleeping pattern and the dosage amount for the particular drug; and

enabling the visual indicators for each compartment in response to the dosage schedule indicating that a particular drug should be taken.
