Abstract

Various embodiments of a wirelessly detectable object to be used in medical procedures are provided. The object may include a piece of absorbent material, a transponder to wirelessly receive and transmit signals, and a cover. The cover is attached directly to the piece of absorbent material to retain the transponder. Methods of manufacturing wirelessly detectable objects are also provided.

Claims

1. A wirelessly detectable object for use in medical procedures, comprising:

a wireless transponder operable to wirelessly receive and transmit signals;

a polyvinyl chloride (PVC) strip;

a fabric laminate secured to the PVC strip to form a pouch, the wireless transponder enclosed within the pouch, and

a piece of absorbent material, the PVC strip attached to the piece of absorbent material, wherein the PVC strip comprises a fabric impregnated with PVC.

2. The wirelessly detectable object of claim 1 wherein the PVC strip is radio-opaque.

3. The wirelessly detectable object of claim 2 wherein the PVC strip comprises a barium material.

4. The wirelessly detectable object of claim 1 wherein the piece of absorbent material is a one of a surgical sponge, a laparotomy (lap) sponge, or a piece of gauze.

5. The wirelessly detectable object of claim 1 wherein the PVC strip includes a sewing area, the sewing area spaced along the PVC strip from the wireless transponder such that the sewing area does not overlie or underlie the wireless transponder.

6. The wirelessly detectable object of claim 1, further comprising:

a set of stitches which secure the PVC strip to the absorbent material.

7. A wirelessly detectable object for use in medical procedures, comprising:

a polyvinyl chloride (PVC) strip that comprises a first piece of fabric impregnated with PVC;

a second piece of fabric secured to the PVC strip to form a pouch therewith;

a wireless transponder operable to wirelessly receive and transmit signals, the wireless transponder enclosed within the pouch; and

a piece of absorbent gauze, the pouch containing the wireless transponder attached to the piece of absorbent gauze.
