Abstract

A medication dispensing device may include a plurality of trays, each tray optionally including a load cell configured to measure a mass/weight of a medication contained in the respective tray. Each tray is placeable in a medication accessible position and a medication inaccessible position. The medication dispensing device includes a user interface configured to provide instructions and/or other information with regard to access for each medication. A processor provides instructions to selectively place each tray in the medication accessible position, and to determine, based on any change in the mass of the medication placed in the medication accessible position, whether the appropriate amount of the medication is removed from the tray.

Claims

1. A medical dispensing device, comprising:

a plurality of trays, each tray including a load cell to measure a mass of a medication contained in each tray, each tray being placeable in a medication accessible position and a medication inaccessible position;

a user interface that provides for user input and instructions to the user to operate and access each medication; and

a computer server communicatively coupled to the user interface and comprising a processor, wherein the computer server receives and stores information input by a user concerning a medication, and, in response to receiving instructions to provide access to the medication, the processor provides instructions to;

obtain a first mass measurement of the medication in a tray;

transition the tray containing the medication from the medication inaccessible position to the medication accessible position;

transition the tray from the medication accessible position back to the medication inaccessible position;

obtain information comprising a second mass measurement of the medication in the tray after the tray is transitioned from the medication accessible position back to the medication inaccessible position;

determine, based on any change in the mass of the medication between the first mass measurement and the second mass measurement, whether any amount of the medication is removed from the tray; and

if an amount of medication is determined to be removed from the tray, responsively calculate the mass of removed medication and determine whether the mass of removed medication matches a prescribed medication dose.

2. The medication dispensing device of claim 1, wherein the plurality of trays are arranged on a vertical axis and are movable horizontally between the medication accessible position and the medication inaccessible position.

3. The medication dispensing device of claim 1, wherein each tray is configurable to receive a medication container including an indicia, the medication dispensing device including a scanner configured to read the indicia.

4. The medication dispensing device of claim 3, wherein the indicia indicates a mass per unit of medication, and the processor determines a number of units of medication removed from the tray.

5. The medication dispensing device of claim 3, wherein the indicia indicates an initial mass of the medication, and the processor verifies that the medication container includes the initial mass of the medication.

6. The medication dispensing device of claim 3, wherein each of the plurality of trays comprises:

a structural tray rotatably mounted to a vertical rod at the vertical axis; and

a container receptacle including at least one container port configured to receive the medication container, wherein the load cell is mounted between the structural tray and the container receptacle.

7. The medication dispensing device of claim 3, further comprising a tray divider positioned between two of the trays such that the tray divider closes a medication container in a bottom one of the two trays when the bottom tray is in the medication inaccessible position.

8. The medication dispensing device of claim 3, wherein each tray comprises a first container port and a second container port, each container port capable of receiving a medication container.

9. The medication dispensing device of claim 8, wherein each tray is rotatable between the medication accessible position, the medication inaccessible position, and a second medication accessible position, wherein a medication container in the first container port is open in the medication accessible position and a medication container in the second container port is open in the second medication accessible position.

10. The medication dispensing device of claim 8, further comprising a motor, operable by the controller to rotate at least one of the plurality of trays between the medication accessible position, the medication inaccessible position, and the second medication accessible position.

11. The medication dispensing device of claim 8, wherein the scanner is positioned to read an indicia of a medication container in the second container port when the tray is in the second medication accessible position.

12. The medication dispensing device of claim 3, wherein the scanner is positioned to read the indicia when the tray is in the medication inaccessible position.

13. The medication dispensing device of claim 12, further comprising a mirror positioned to reflect an image of the indicia to the scanner when the tray is in the medication inaccessible position.

14. The medication dispensing device of claim 3, wherein at least one of the trays includes a second indicia readable by the scanner when the medication container tray does not include a container, the second indicia indicating that the medication container tray is empty.

15. The medication dispensing device of claim 3, wherein the medication dispensing container has a sloped surface facilitating removal of the medication.

16. The medication dispensing device of claim 1, further comprising a peripheral device configured to obtain a biometric reading from a patient, wherein the user interface instructs a user to use the peripheral device and the processor reports the biometric reading to a network application.
