System and method of monitoring the door of a secure cabinet for holding pharmaceutical products
First Claim
1. A storage container for medical pharmaceuticals, the container comprising:
- a frame that defines a partially enclosed space that is configured to receive medical pharmaceuticals, wherein the frame defines an opening;
a door mounted to the frame so as to be movable between an open position, whereby access to the medical pharmaceuticals can be obtained, and a closed position whereby the medical pharmaceuticals can be secured within the partially enclosed space;
a locking mechanism that secures the door to the frame in the closed position; and
a lock verification system that includes a first component mounted on the door and a second component mounted on the frame, wherein the first component and the second component are inductively coupled so that when the first component and the second component are positioned in a first orientation relative to each other with the door in the closed position a first signal indicating that the door is closed is generated and wherein the second component transmits a first identifier to the first component when the first component and the second component are positioned in the first orientation, the first component compares the first identifier to a second identifier and generates the first signal if the first identifier corresponds to the second identifier.

Abstract
In one embodiment, a pharmaceutical cabinet comprises sensors positioned within the frame and door of the cabinet, and the sensors are arranged in a predetermined orientation when the door is closed and a lock is actuated. The sensors are configured to communicate with one another when brought into the predetermined orientation to confirm that the door is closed and the lock is actuated. One or both of the sensors may transmit an identifier to the other sensor, and the communication between the sensors may be encoded. The cabinet also includes a sensor on the lock that indicates if the lock is engaged. The cabinet may generate a record of the times the sensors are moved into or out of communication and the times that the lock is engaged.

8. A storage container comprising:
-
a frame that defines a partially enclosed space that is configured to receive medical pharmaceuticals, wherein the frame defines an opening; a door mounted to the frame so as to be selectively movable between an open position and a closed position; and a first sensor mounted on the door and a second sensor mounted on the frame, wherein the first sensor comprises a first signal source configured to generate a first signal; a first interface coupled to the signal source, wherein the first interface is configured to inductively transmit the first signal and receive a second signal when positioned in a first orientation relative to the second sensor; and
wherein the second sensor comprisesa second signal source configured to generate a second signal; a second interface coupled to the second signal source, wherein the second interface is configured to receive the first signal and inductively transmit the second signal when positioned in the first orientation and wherein the first sensor is further configured to add the first signal to the second signal to create a combined signal, and wherein the first sensor further comprises a filter that receives the combined signal and removes the first signal from the combined signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A lock audit system comprising:
-
a locking mechanism configured to lock a door to a frame in a closed position when the door is in the closed position and the locking mechanism is engaged; a lock sensor coupled to the locking mechanism and configured to generate a locking signal that indicates if the locking mechanism is engaged; means for detecting if the door and the frame are in the closed position; means for generating a second closed signal if the door and frame are in the closed position; a controller configured to receive the lock signal and the closed signal and determine if the door is locked and closed based on the lock signal and the closed signal, and wherein the controller generates a record of the times that the door is locked and the times that the door is closed wherein the controller receives the closed signal as an interference pattern of the lock signal. - View Dependent Claims (18)
