Medical technology station and method of use
The invention includes a medical technology station and a method for using the medical technology cart. The station can be a portable cart that can be movable, such as rollable, and has a computer system. Attached to the cart is a housing that communicates with the computer system. Insertable in the housing is a cassette system that includes a series of drawers. The drawers are openable and preferably closeable on command from a user. The drawers have a readable unique drawer identifier that is readable by sensors in the cassette. The cassette also preferably includes proximity sensors, while the drawers contain a target for the proximity sensors. In use, an operator, with proper credentials, can, though the computer system, identify a drawer to be opened by the computer system. The cassette and drawers can be removed from the housing and transported to another location for filling of the drawers with medications or other supplies.
1. A medical station comprising:
(a) a movable cart;
(b) a computer system comprising an input device, a display device, and a processor, the computer system positioned on the cart and including computer memory in communication with the processor;
(c) a housing mounted on the cart;
(d) at least one portable cassette system removably coupled to the housing, wherein the processor is in electronic communication with the input device, the display device, and the cassette system; and
(e) wherein the cassette system comprises:
(i) a cassette frame defining an interior divided into compartments;
(ii) drawers, each of the drawers occupying, and being slidably positioned in, at least one of the compartments;
(iii) each of the compartments having an actuator associated therewith in communication with the processor and associated with an actuator latch that is movable in response to operation of the associated actuator;
(iv) each of the drawers having at least one drawer latch, and each of the drawers capable of moving from a locked and closed position to an unlocked position in response to movement from the associated actuator latch;
(v) whereby the computer system is configured to automatically transition a specific one of the drawers from the unlocked position to the locked position where the specific one of the drawers remains in the unlocked position for at least a selected period of time.
2. The medical station of claim 1 , wherein the computer system is configured to move the specific one of the drawers into the unlocked position by movement of the actuator associated with the specific one of the drawers in response to receipt of an open drawer command for the specific one of the drawers received from the input device.
3. The medical station of claim 1 , further comprising
electronically readable identifier tags, each associated with one of the drawers and comprising a unique drawer identifier; and
electronic readers, each associated with one of the drawers and configured to read the identifier tags, wherein the computer system is configured to identify a position of each of the drawers in the cassette frame based on positions of the electronic readers relative to the unique identifiers for the drawers.
4. The medical station of claim 3 , whereby in response to a drawer open command, the actuator associated with a specific one of the drawers actuates to move the actuator latch of the specific one of the drawers from the locked and closed position to an unlocked and almost closed position.
5. The medical station of claim 1 , further comprising a series of proximity sensors each in electrical communication with the processor, each of the drawers being associated with one of the series of proximity sensors.
6. The medical station of claim 5 , wherein the computer system is configured to detect whether one of the drawers is in a closed position or an almost closed position based on output of the proximity sensors.
7. The medical station of claim 3 , wherein each of the identifier tags comprise a radio frequency identifier (RFID) tag.
8. The medical station of claim 7 , wherein each of the RFID tags also indicate a number of the compartments occupied by an associated one of the drawers.
9. The medical station of claim 7 , wherein the computer system is configured to classify a respective one of the drawers as in an open position when the proximity sensor associated with the respective one of the drawers is not detected.
10. The medical station of claim 7 , wherein the electronic readers are capable of reading the RFID tag of a first one of the drawers one which is in a closed position, but are not capable of reading the RFID tag of an adjacent one of the drawers when the adjacent one of the drawers is in the closed position.
11. The medical station of claim 10 , wherein the electronic readers are configured to read only the RFID tag of the first one of the drawers by way of a low power signal which is incapable of energizing the RFID tag of the adjacent one of the drawers.
12. The medical station of claim 1 , wherein the computer system is configured to prevent a second one of the drawers from movement into an opened position when a first one of the drawers is in the opened position, unless the computer system receives at least one of an override command, an administrator access command, or a pharmacy access command.
13. The medical station of claim 1 , wherein the cassette system further comprises:
(a) a spring-loaded graspable handle slidably mounted on the cassette frame for movement between a closed position when the handle is not accessible or graspable by a user and released position; and
(b) a handle actuator mounted to the housing for moving the handle between the closed position and the released position.
14. The medical station of claim 1 , further comprising a configuration map located in the computer memory, the configuration map comprising, for each respective one of the drawers, a unique drawer identifier and an indicator of a location of the respective one of the drawers in an interior of the cassette frame.
15. The medical station of claim 1 , wherein the cassette system includes a drawer manual override configured to allow a hardware key to mechanically unlatch all of the actuator latches so that the drawers are capable of opening.
16. The medical station of claim 15 , wherein the housing includes a cassette manual override allowing the cassette system to be mechanically unlocked and removed from the housing.
17. The medical station of claim 16 , wherein the cassette manual override includes a lockable cassette handle activated by a manual hardware key.
