Abstract

An automatic identification system for accounting for and identifying a plurality of surgical sponges used during a surgical procedure. Machine-readable information is located on a plurality of surgical sponges. Each sponge of the plurality of surgical sponges has unique machine-readable information located thereon. The unique machine-readable information is unique for at least one surgical procedure.

Claims

1. An automatic identification system for use with a reading device, said automatic identification system for accounting for and identifying a plurality of surgical sponges used during a surgical procedure, comprising:

machine-readable information located on a plurality of physically unconnected surgical sponges, wherein each sponge of said plurality of surgical sponges has its own differentiating machine-readable information located thereon which will not repeat on any other sponge used in a given surgical procedure, said machine-readable information being readable by a reading device, wherein the physically unconnected surgical sponges can be recognized and accounted for during a surgical procedure without reliance on human visual detection and counting ability to identify. differentiate and account for the surgical sponges.

2. The automatic identification system of claim 1, wherein said unique machine-readable information is located on a substrate, said substrate positioned on a respective surgical sponge.

3. The automatic identification system of claim 1, wherein each said surgical sponge further includes an x-ray detectable element.

4. The automatic identification system of claim 1, wherein said machine-readable information is contained within said surgical sponge.

5. The automatic identification system of claim 1, wherein said machine-readable information is contained on said surgical sponge.

6. The automatic identification system of claim 1, wherein each of said plurality of surgical sponges further comprises unique human-readable information thereon associated with its respective unique machine-readable information.

7. The automatic identification system of claim 1, wherein said information is made to be body fluid repellant to prevent obscuration thereof during reading.

8. The automatic identification system of claim 7, wherein said substrate comprises a thin film.

9. The automatic identification system of claim 2, wherein said substrate is formed of inert material.

10. The automatic identification system of claim 1, wherein said machine-readable information comprises bar code information.

11. The automatic identification system of claim 1, wherein said machine-readable information comprises compressed symbology.

12. The automatic identification system of claim 1, wherein said unique machine readable information is located on a substrate, said substrate positioned on a respective sponge, said substrate comprising an adhesive for attaching said substrate to the surgical sponge.

13. The automatic identification system of claim 12, wherein said adhesive comprises an x-ray detectable element.

14. The automatic identification system of claim 13, wherein said x-ray detectable element comprises barium sulfate.

15. The automatic identification system of claim 12, wherein said adhesive is of a type which provides attachment by the application of heat thereto.

16. The automatic identification system of claim 1, wherein said machine readable information is located on a substrate, said substrate being positioned on a respective sponge, said substrate comprising biologically inert material.

17. A surgical sponge system for accounting for and identifying a plurality of surgical sponges used during a surgical procedure, comprising:

a plurality of surgical sponges, each sponge having unique machine readable information located thereon, wherein said unique machine readable information is unique for at least one surgical procedure.

18. The automatic identification system of claim 17, wherein said unique machine-readable information is located on a substrate, said substrate positioned on a respective surgical sponge.

19. The automatic identification system of claim 17, wherein each said surgical sponge further includes an x-ray detectable element.

20. The automatic identification system of claim 17, wherein said machine-readable information is contained within said surgical sponge.

21. The automatic identification system of claim 17, wherein said machine-readable information is contained on said surgical sponge.

22. The automatic identification system of claim 17, wherein each of said plurality of surgical sponges further comprises unique human-readable information thereon associated with its respective unique machine-readable information.

23. The automatic identification system of claim 17, wherein said information is made to be body fluid repellant to prevent obscuration thereof during reading.

24. The automatic identification system of claim 23, wherein said substrate comprises a thin film.

25. The automatic identification system of claim 18, wherein said substrate is formed of inert material.

26. The automatic identification system of claim 17, wherein said machine-readable information comprises bar code information.

27. The automatic identification system of claim 17, wherein said machine-readable information comprises compressed symbology.

28. The automatic identification system of claim 17, wherein said unique machine readable information is located on a substrate, said substrate positioned on a respective sponge, said substrate comprising an adhesive for attaching said substrate to the surgical sponge.
