Apparatus for automating the counting of sharps using RFID tags
View Patent ↗Systems and methods are provided for counting sharps returned to a container. An example method of counting sharps returned to a container having at least two layers of penetrable conductive material includes periodically checking a plurality of circuits formed by the first and second layers of material to determine if each circuit is open or closed, and keeping a count of the number of closed circuits.
1. A system for electronically counting sharps, said system comprising:
a reader configured to detect a tag on sharps packaging material to establish an in-count representative of a number of sharps available for use in a surgical procedure;
a disposable sharps container defining a volume, said volume configured to contain a plurality of sharps, said disposable sharps container is configured to count a number of closed circuits, and is configured such that a sharp placed within said volume acts as a conductor in one of said closed circuits; and
a remote device in communication with said disposable sharps container and said reader,
wherein said disposable sharps container and said remote device, are collectively configured to electronically count a number of sharps placed within said volume to establish an out-count of said sharps and compare said out-count of sharps with said in-count of sharps.
2. The system of claim 1 , wherein said disposable sharps container comprises a plurality of electronic contacts.
3. The system of claim 1 , wherein said disposable sharps container comprises a capacitive sensing module.
4. The system of claim 1 , wherein said remote device is further defined as a base station.
5. The system of claim 1 , wherein said disposable sharps container is physically connected to said remote device.
6. The system of claim 1 , wherein said remote device is in radio communication with said disposable sharps container.
7. The system of claim 1 , wherein said disposable sharps container further comprises a transponder and said remote device comprises a second reader, said second reader in communication with said transponder.
8. The system of claim 7 , wherein said second reader is a receiver.
9. The system of claim 7 , wherein said transponder is an RFID tag.
10. The system of claim 1 , wherein said remote device comprises a memory unit, said memory unit storing said number of sharps electronically counted within said disposable sharps container.
11. The system of claim 1 , wherein said remote device comprises a microcontroller.
12. The system of claim 1 , wherein said remote device comprises a display unit, and wherein said remote device is configured to display said number of sharps electronically counted within said disposable sharps container on said display unit.
13. The system of claim 1 , wherein said remote device is configured to indicate that one or more sharps are not accounted for when said out-count number of sharps does not equal said in-count.
