Abstract

In accordance with the teachings described herein, 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.

Claims (7)

1. A sharps container having a magnetic material and at least one pair of contacts, and circuitry for determining the condition, open or closed, of said pair of contacts.

2. The container of claim 1 , wherein a sharp being placed between the at least one pair of contacts closes a circuit.

3. The container of claim 1 , additionally comprising means for generating an in count.

4. The container of claim 2 , additionally comprising means for comparing the in count with the count of closed circuits.

5. The container of claim 1 , wherein the circuitry includes a microcontroller.

6. The container of claim 1 , wherein the circuitry communicates data related to the condition of the circuits formed by the at least one pair of contacts to an RFID receiver.
