Abstract

A method and apparatus that is attachable to a receptacle for timing a predetermined interval according to a timing schedule of a set of timing schedules. The apparatus has an electronic timing circuit that provides an alarm signal at the expiration of the predetermined time interval. The timing circuit includes a set of inputs and a set of outputs that are both connected to processing circuitry. The processing circuitry defines the set of selectable timing schedules. The inputs correspond to the timing schedules, and the outputs issue the alarm signals. The apparatus also includes a sensing mechanism for selectively engaging an input based on the position of the mechanism. Each timing schedule is selectable by the device through the inputs that are engaged and disengaged.

Claims

1. A device including a can attachable to a receptacle for coacting therewith in enclosing medication and timing a predetermined interval for taking the medication defined by one timing schedule of a set of selectable timing schedules, the device comprising:

an electronic timing circuit constructed and arranged to provide an alarm signal designating a time for taking the medication at the expiration of a predetermined time interval defined by the timing schedule;

said electronic timing circuit being housed in said cap and including schedule processing circuitry that defines the set of selectable timing schedules, and a set of outputs for issuing electrical signals at the expiration of the predetermined time interval;

a sensing mechanism housed in said cap for selectively engaging an input corresponding to a selected one of the timing schedules of the set; and

the sensing mechanism electrically engaging the input when in a first position and electrically disengaged from the input when in a second position.

2. The device of claim 1 wherein the sensing mechanism is in mechanical communication with the selectively engaged input.

3. The device of claim 2 wherein the sensing mechanism is constructed and arranged to move between the first and second positions in response to a nonfrictional normal force.

4. The device of claim 1 wherein the engaged input causes an electrical current to pass through the engaged input to the timing circuit to establish the selected one of the timing schedules.

5. The device of claim 1 further comprising at least one alarm transducer housed in said cap coupled to the timing circuit responsive to the alarm signal for providing a sensible alarm.

6. The device of claim 5 further comprising first and second alarm transducers for providing first and second sensible alarms respectively.

7. The device of claim 6 wherein the first and second sensible alarms are visual and audible respectively.

8. The device of claim 1 further comprising a power source housed in said cap and an activation mechanism housed in said cap having an activated position and a deactivated position, wherein the activation mechanism engages the electronic timing circuit to electrically connect the power source to the timing circuit when in the activated position, and wherein the power source is disengaged from the timing circuit when the activation mechanism is in the deactivated position.

9. The device of claim 1 wherein the electronic timing circuit includes a reset input and further comprises a reset mechanism in communication with the electronic timing circuit such that the reset mechanism is capable of engaging the reset input to activate a set of functions defined by the processing circuitry.

10. The device of claim 1 wherein the electronic timing circuit includes synchronization circuitry for synchronizing the predetermined timing interval schedule relative to an event external to the device.

11. The device of claim 1 wherein the electronic timing circuit includes muting circuitry for suppressing the alarm signal when the device is not in use.

12. The device of claim 1 wherein the electronic timing circuit includes alarm preempt circuitry for suppressing the alarm signal when the sensing mechanism moves between the first and second positions within a predetermined subinterval.

13. The device of claim 12 wherein the predetermined subinterval is an interval extending prior to and until the expiration of a time interval of the predetermined timing interval schedule.

14. The device of claim 1 wherein the electronic timing circuit includes shut down circuitry for suppressing the alarm signal after a predetermined duration.

15. The device of claim 1 wherein the electronic timing circuit includes start delay circuitry for beginning an operational duration of the device upon an initiating event.

16. A method of timing a predetermined interval schedule defined by one schedule of a set of different timing schedules stored in the cap attachable to a receptacle, said cap housing an electronic circuit constructed and arranged to provide an alarm signal designating a time for taking medication in the receptacle at the expiration of a predetermined time interval defined by the predetermined interval schedule and housing a sensing mechanism for selectively engaging an input corresponding to the predetermined interval schedule comprising:

electromechanically selecting the predetermined interval schedule through the cap establishing a predetermined time interval as defined by the predetermined interval schedule; and

issuing said alarm signal upon expiration of the predetermined time interval.

17. The method of claim 16 further comprising:

relatively displacing the cap and receptacle to open the receptacle; and

discontinuing the alarm signal in response to opening of the receptacle.

18. The method of claim 16 wherein the set of timing schedules includes timing schedules corresponding to different patient types.

19. The method of claim 16 wherein the can has a power source that is initially dormant and further comprising activating the power source of the cap.

20. The method of claim 16 further comprising:

sensing when the receptacle is not in use, and suppressing the alarm signal when the receptacle is not in use.

21. The method of claim 16 further comprising synchronizing the selected timing schedule to an external event.

22. The method of claim 16 further comprising suppressing the alarm signal after a predetermined duration.

23. A cap of a container for attachment to a receptacle of the container, the cap comprising:

an electronic timing circuit constructed and arranged to provide an alarm signal at the expiration of a predetermined time interval defined by a timing schedule of a set of selectable timing schedules;

said electronic timing circuit being housed in the cap and including schedule processing circuitry that defines the set of selectable timing schedules, and an output for issuing electrical signals at the expiration of the predetermined time interval;
