Abstract

A surgical drape of the invention has a main sheet having a pressure sensitive adhesive on its top and bottom surfaces. The adhesive on the bottom surface extends over at least the major portion of that surface and serves to secure the drape to a patient, thereby providing a sterile surgical field and preventing migration of bacteria to or from an incision site along a path between the drape and the skin of the patient. The adhesive on the top surface of the drape extends over a limited area of that surface convenient to the incision site and serves as an anchoring means to which additional surgical drapes, towels, and the like may be secured. The exposed faces of the pressure sensitive adhesive on the bottom and top surfaces of the drape are covered with nonadhesive, removably adhered protective covering sheets to facilitate packaging and handling prior to use of the drape on a patient. These protective covering sheets are commonly referred to as '"'"''"'"''"'"''"'"'release sheets.

Claims

1. A surgical drape adapted to be placed on the body of a patient comprising:

a main sheet having a top surface and a bottom surface, siad main sheet carrying normally tacky and pressure sensitive adhesive means on a major portion of its bottom surface for securing said main sheet to the body of a patient;

normally tacky and pressure sensitive adhesive means carried on the top surface of said main sheet in a limited area, said limited area of adhesive means providing anchoring means for securing operating room articles to said main sheet.

2. A surgical drape adapted to be placed on the body of a patient comprising:

a main sheet having a top surface and a bottom surface;

said main sheet carrying normally tacky and pressure sensitive adhesive means on a major portion of its bottom surface for securing the main sheet to the body of a patient;

a release sheet at least coextensive with said major portion of adhesive and removably adhered thereto;

normally tacky and pressure sensitive adhesive means carried on the top surface of said sheet in a limited area, said limited area of adhesive means being located so as to be convenient to an incision site when thE drape is secured to a patient; and

a release sheet at least coextensive with said limited area and removably adhered thereto, said limited area of adhesive providing a normally protected, yet readily exposable anchoring means for securing operating room articles to said main sheet.

3. A surgical drape according to claim 2 wherein said adhesive on said top surface is applied in the form of a border lying adjacent the edges of the main sheet.

4. A surgical drape according to claim 2 wherein said release sheet on the adhesive means on the top surface of the main sheet extends beyond an edge of the adhesive means to form a gripping portion whereby removal of said release sheet from the adhesive is facilitated.

5. A surgical drape according to claim 4 wherein the release sheet on the adhesive means on the bottom surface of the main sheet extends beyond an edge of the adhesive means to form a gripping portion whereby removal of said release sheet from the adhesive is facilitated.

6. A surgical drape according to claim 2 wherein said main sheet comprises a nonwoven fabric.

7. A surgical drape according to claim 2 wherein said main sheet comprises a thin plastic film.

8. A surgical drape according to claim 7 wherein said film comprises polyvinyl chloride.

9. A surgical drape according to claim 7 wherein said film comprises a copolymer of ehtylene and an acrylate ester.

10. A surgical drape according to claim 7 wherein said film comprises polyethylene.

11. A surgical drape according to claim 2 wherein opposed marginal edge portions on the bottom surface of said main sheet are free of adhesive.

12. A surgical drape according to claim 11 wherein control tabs are adhered to the main sheet adjacent its side edges.

13. A surgical drape adapted to be placed on the body of a patient comprising:

a main sheet having a top surface and a bottom surface;

said main sheet carrying normally tacky and pressure sensitive adhesive means on a major portion of its bottom surface for securing the main sheet to the body of a patient;

a release sheet at least coextensive with said major portion of adhesive and removably adhered thereto;

said main sheet carrying two strips of normally tacky and pressure sensitive adhesive means on its top surface;

each of said strips of adhesive means having a release sheet at least coextensive therewith and removably adhered thereto;

said strips of adhesive means providing a normally protected, yet readily exposable anchoring means for securing operating room articles to said main sheet.

14. A surgical drape according to claim 13 wherein said two strips of adhesive means are in a spaced-apart, parallel relationship.

15. A surgical drape according to claim 13 wherein said two strips of adhesive means extend from one end of the drape to the other.

16. A surgical drape according to claim 15 wherein said main sheet comprises a thin plastic film and each removably adhered release sheet extends beyond an edge of the strip of adhesive means which it covers to provide a gripping portion whereby removal of said release sheet is facilitated.

17. A surgical drape according to claim 16 wherein control tabs are adhered to the top surface of said main sheet adjacent its side edges.

18. A surgical drape according to claim 17 treated to render it sterile and individually packaged in said sterile condition.
