Abstract

A pill dispenser is disclosed that includes a pill-dispensing mechanism, a receptacle, an identifying camera positioned to capture an image of an area adjacent to the pill dispenser, and a processor in operative communication with the pill-dispensing mechanism and the identifying camera.

First claim

What is claimed:

1. A method of dispensing a pill comprising:
providing a pill-dispensing mechanism having a pill-viewing area, first and second pill-viewing cameras, a pill-holding area outside an opening in the pill-dispensing mechanism, and at least one processor in operative communication with the first and second pill-viewing cameras and pill-dispensing mechanism;
dispensing a pill to said pill-viewing area;
capturing an image of said pill-viewing area with the first pill-viewing camera;
using said captured image to verify said dispensed pill is in said pill-viewing area; and
identifying said pill using said captured image.

2. The method of claim 1 , wherein the at least one processor identifies the pill using at least one of a color of the pill, a shape of the pill, characters on the pill, and a plurality of colors of the pill as determined using the captured image.

3. The method of claim 1 , wherein the pill-viewing area is internal to the pill-dispensing mechanism.

4. The method of claim 1 , the pill dispensing mechanism further comprising:
a scale, wherein the at least one processor is in operative communication with the scale and receives a weight therefrom.

5. The method of claim 4 , further comprising:
estimating a weight of said pill using said scale; and
identifying the pill based upon, at least in part, said estimated weight.

6. The method of claim 5 , further comprising:
estimating the weight of the pill by subtracting an estimated weight of the scale.

7. The method of claim 1 , further comprising:
dispensing said pill from said pill-viewing area to said pill-holding area;
capturing a second image of said pill-holding area via said second pill-viewing camera;
verifying said dispensed pill is in said pill-holding area; and
identifying said pill using said second captured image.

8. The method of claim 1 , wherein the pill-viewing area is internal to the pill-dispensing mechanism.

9. The method of claim 1 , wherein the at least one processor identifies the pill using at least one of a color of the pill, a shape of the pill, characters on the pill, and a plurality of colors of the pill as determined using the first and second captured images.

10. The method of claim 1 , the pill dispensing mechanism further comprising:
a scale, wherein the at least one processor is in operative communication with the scale and receives a weight therefrom.

11. The method of claim 10 , further comprising:
estimating a weight of said pill using said scale; and
identifying the pill based upon, at least in part, said estimated weight.

12. The method of claim 1 , wherein the at least one processor does not dispense the pill unless the identity of the pill is determined to be appropriate based on information from at least one of an electronic medical record, a drug error reduction system, or a monitoring client.
