Abstract

A pill dispenser for dispensing pills of various sizes includes a pill storage section, a dispensing section located at a lower end of the storage section, an optical sensor, a memory and a controller. The dispensing section includes a device for adjusting a variable size cavity configured to adjust to various pill sizes. The controller adjusts the variable size cavity of the dispensing section depending on the individual pill specifications, and determines if the optical sensor has sensed presence of the pill to be dispensed.

Claims

1. An apparatus for dispensing pills of various sizes, the apparatus comprising:

a storage section for storing pills to be dispensed;

a dispensing section connected to said storage section to dispense pills stored in said storage section through an outlet;

said dispensing section including an adjusting device to adjust a variable size cavity for receiving from said storage section a pill to be dispensed and an ejecting device for ejecting the pill from the variable size cavity;

a controller for controlling said dispensing section; and

a sensor to detect the pill to be dispensed, said sensor communicating with said controller,

wherein said controller controls said adjusting device to adjust a size of the variable size cavity according to a size of the pill to be dispensed, controls said ejecting device to eject the pill from the variable size cavity, and receives a signal from the sensor when the pill has been successfully ejected from the variable size cavity.

2. The apparatus according to claim 1, wherein said dispensing section defines the variable size cavity with a sizing ring, a movable dispensing ring, and a movable depth ring,

wherein said controller controls said dispensing section to position the movable dispensing ring at a predetermined rest position relative to the sizing ring in order to establish a maximum width of the variable size cavity, and to position the movable depth ring in a vertical direction to establish a depth of the variable size cavity.

3. The apparatus according to claim 2, wherein operation of said ejecting device comprises rotating the dispensing ring, relative to the sizing ring and the depth ring, to push the pill toward an opening in the depth ring to dispense the pill.

4. The apparatus according to claim 1, further comprising an alarm to provide an indication to a user at a time to take a pill and a memory storing prescribed dosing requirements for the pill and a last time medication was dispensed,

wherein said controller controls said alarm based on the dosing requirements and the time stored in said memory.

5. The apparatus according to claim 4, wherein said controller controls said alarm to operate in one mode when said controller determines it is time for the user to take the pill and to operate in another mode at all other times.

6. The apparatus according to claim 5, wherein said alarm is at least one of an audio alarm, a visual alarm, and a vibrating alarm.

7. The apparatus according to claim 1, wherein said sensor is an optical sensor which optically detects physical properties of the pill.

8. The apparatus according to claim 7, further comprising an alarm and a memory storing specifications of physical properties of the pills,

wherein when said controller determines that the physical properties of the pill detected by said sensor do not match the pill specification stored in said memory, said alarm alerts a user and/or another party.

9. The apparatus according to claim 8, wherein said memory further stores dosing requirements for the pills and the time medication was last dispensed and said controller controls said alarm based on the dosing requirements and time stored in said memory, and

wherein when said controller determines that the physical properties of the pill detected by said sensor do not match the pill specification stored in said memory, said alarm alerts a user by emitting an alarm different from an alarm indicating to a user it is time to take a pill.

10. The apparatus according to claim 1, further comprising a memory storing prescribed dosing requirements for the pill and a communication device for communicating with a central database and providing information regarding compliance with the dosing requirements stored in said memory.

11. The apparatus according to claim 2, further comprising a ramp for guiding a pill to be dispensed from said storage section to said dispensing section, wherein the sizing ring further includes a protrusion configured as a backstop for the pill to be dispensed as the pill enters the dispensing ring from the ramp.

12. The apparatus according to claim 1, furthering comprising:

a removable top portion covering said storage section;

another sensor to determine if the removable top portion has been removed from said storage section; and

an actuator, located on said removable top portion, for beginning a dispensing process of the pill.

13. A method of operating a pill dispenser, comprising the steps of:

determining if an elapsed time is at least equal to a predetermined time period;

alerting a user when the elapsed time is at least equal to the predetermined time period;

determining whether the user has actuated the dispenser to release a pill from the pill dispenser;

releasing the pill from the pill dispenser if the dispenser has been activated,

wherein said releasing step comprises positioning a pill to be dispensed in a dispensing cavity defined by a sizing ring, a dispensing ring and a depth ring set to a size of a specific pill, moving the dispensing ring relative to the sizing ring and the depth ring to move a single pill, and determining by a sensor that the pill has been dispensed.

14. The method of operating a pill dispenser according to claim 13, further comprising a step of initially calibrating a size of the cavity of the pill dispenser by:

(i) adjusting a starting location of the dispensing ring relative to the sizing ring according to a specified pill size stored in a memory; and

(ii) adjusting a height of the depth ring relative to the dispensing ring according to the specified pill size.

15. The method according to claim 13, wherein the user is alerted during said alerting step by an alarm including at least one of an audio alarm, a visual alarm, and a vibrating alarm.

16. The method according to claim 15, wherein the alarm operates in one mode when said determining step determines an elapsed time is at least equal to a predetermined time period and operates in another mode at all other times.

17. The method according to claim 13, wherein the sensor is an optical sensor which detects the physical properties of the pill.

18. The method according to claim 17, wherein said alerting step includes alerting a user by an alarm when the physical properties of the pill detected by the sensor do not match information stored in a memory,

wherein the alarm alerts a user either by an audio alarm, a visual alarm or a vibrating alarm.
