The present invention is directed toward a surgical drape having a base sheet and an absorbent sheet with at least one opening. A transparent or clear sheet is attached to the edges of the opening and has at least one fenestration for performing surgery when the drape is covering a patient.

Claims

1. A surgical drape comprising:

a base sheet having an upper surface, a lower surface, and at least one opening;

an absorbent sheet being positioned on the upper surface of said base sheet and having at least one opening aligned with the opening of said base sheet; and

a transparent sheet attached to said opening of said base sheet and absorbent sheet, wherein a fenestration is formed in the transparent sheet through which a surgical procedure may be performed when the drape is covering a patient.

2. The surgical drape of claim 1 wherein said absorbent sheet comprises non-woven fabric.

3. The surgical drape of claim 1 wherein said base sheet comprises polyethylene.

4. The surgical drape of claim 1 wherein said transparent sheet is hydrophobic.

5. The surgical drape of claim 1 wherein said transparent sheet comprises a low-density polyethylene film.

6. The surgical drape of claim 1 further comprising a layer of adhesive on a lower surface of said transparent sheet substantially surrounding said fenestration.

7. The surgical drape of claim 6 wherein said adhesive layer comprises a pressure-sensitive biologically acceptable adhesive.

8. The surgical drape of claim 6 further comprising a release liner on said adhesive layer.

9. The surgical drape of claim 7 wherein said release liner comprises wax-coated paper, silicone-coated paper or plastic materials having at least one non-adherent surface.

10. The surgical drape of claim 7 wherein said release liner is segmented.

11. The surgical drape of claim 7 wherein said release liner is removed and said surgical drape is placed over a patient so that said fenestration is placed over a surgery site.

12. The surgical drape of claim 6 wherein said adhesive sticks to the skin of a patient.

13. The surgical drape of claim 1 wherein said absorbent sheet is attached to said base sheet by an adhesive, stitching, thermal bonding or ultrasonic bonding.

15. A surgical drape comprising:

an opaque absorbent sheet surrounding a clear sheet having a fenestration, wherein said clear sheet has an adhesive coating on at least a portion of said clear sheet surrounding said fenestration.

16. The surgical drape of claim 15 wherein a release liner is on said adhesive coating.

17. The surgical drape of claim 15 wherein said absorbent sheet comprises non-woven fabric.

18. The surgical drape of claim 15 wherein said clear sheet comprises a low-density polyethylene film.

19. The surgical drape of claim 16 wherein said release liner is segmented.

20. The surgical drape of claim 15 wherein said drape has a plurality of fenestrations.

21. A surgical drape comprising:

an absorbent outer layer having at least one opening;

an inner layer, adapted to contact a patient having at least one opening aligned with said opening of said absorbent outer layer; and

a transparent sheet having at least one fenestration attached to said at least one opening.

22. A surgical drape comprising:
