Abstract

A medication dispensing cabinet, a computing device and an associated method are provided to measure the force applied to a drawer of a medication dispensing cabinet. By measuring the force applied to the drawer of a medication dispensing cabinet, certain predefined condition(s) may be detected, such as the closure of a drawer of a medication dispensing cabinet with an excessive amount of force. In this regard, a medication dispensing cabinet is provided that includes a cabinet body defining an internal cavity and a plurality of drawers disposed within the internal cavity of the cabinet body. The drawers are configured to be slidably opened and closed relative to the cabinet body. The medication dispensing cabinet also includes a force sensor carried by at least one of the cabinet body or one or more of the drawers and configured to measure force applied to a drawer of the medication dispensing cabinet.

Claims

1. A medication dispensing cabinet comprising:

a cabinet body defining an internal cavity;

a plurality of drawers comprising a plurality of pockets configured to store medication disposed within the internal cavity of the cabinet body and configured to be slidably opened and closed relative to the cabinet body;

a force sensor carried by at least one of the cabinet body or one or more of the drawers and configured to measure force applied to a drawer of the medication dispensing cabinet; and

processing circuitry providing a notification in response to one or more predefined conditions being detected by the force sensor, wherein at least one of the one or more predefined conditions comprises an increase in average force over time.

2. A medication dispensing cabinet according to claim 1 wherein the force sensor is carried by a drawer and is configured to slidably move with the drawer relative to the cabinet body.

3. A medication dispensing cabinet according to claim 2 wherein the drawer includes opposed front and rear ends with the front end facing outwardly from the cabinet body, and wherein the force sensor is mounted to the drawer proximate the rear end.

4. A medication dispensing cabinet according to claim 2 wherein the drawer includes opposed sides, and wherein the force sensor is mounted to a central portion of the drawer between the opposed sides.

5. A medication dispensing cabinet according to claim 1 wherein the force sensor comprises an accelerometer.

6. A medication dispensing cabinet according to claim 1 further comprising a memory configured to store information relating to measurements of the force captured by the force sensor.

7. A medication dispensing cabinet according to claim 1 wherein the processing circuitry is configured to monitor information relating to measurements of the force captured by the force sensor and wherein at least one of the one or more predefined conditions comprises an instance in which the force applied to the drawer exceeds a predefined threshold.

8. A computing device for association with a medication dispensing cabinet, the computing device comprising processing circuitry configured to:

receive an indication of force applied to a drawer of the medication dispensing cabinet;

cause storage of information relating to measurements of the force applied to the drawer; and

process the information relating to measurements of the force applied to the drawer to detect one or more predefined conditions wherein at least one of the one or more predefined conditions comprises an increase in average force over time, wherein the drawer comprises a plurality of pockets configured to store medication.

9. A computing device according to claim 8 wherein the processing circuitry is configured to process the information by detecting an instance in which the force applied to the drawer exceeds a predefined threshold.

10. A computing device according to claim 8 wherein the processing circuitry is further configured to provide a notification in an instance in which a predefined condition is detected.

11. A computing device according to claim 8 wherein the processing circuitry is configured to receive an indication of the force from a force sensor carried by at least one of the cabinet body or the drawer and configured to measure the force.

12. A computing device according to claim 11 wherein the force sensor comprises an accelerometer.

13. A method of monitoring a medication dispensing cabinet comprising:

measuring force applied to a drawer of the medication dispensing cabinet;

causing storage of information relating to measurements of the force applied to the drawer; and

processing the information relating to measurements of the force applied to the drawer to detect one or more predefined conditions wherein at least one of the one or more predefined conditions comprises an increase in average force over time, wherein the drawer comprises a plurality of pockets configured to store medication.

14. A method according to claim 13 wherein processing the information comprises detecting an instance in which the force applied to the drawer exceeds a predefined threshold.

15. A method according to claim 13 further comprising providing a notification in an instance in which a predefined condition is detected.

16. A method according to claim 13 wherein measuring the force applied to the drawer comprises measuring the force applied to the drawer with a force sensor carried by at least one of the cabinet body or the drawer.

17. A method according to claim 16 wherein the force sensor comprises an accelerometer.
