Abstract
Abstract A surgical drape includes a main drape body of suitable material, with a fenestration disposed therein. A sheet of imperforate transparent film is provided with at least one surface coated with a tacky adhesive. The film is dimensioned larger than the fenestration and is positioned with the tacky surface adhering to the drape body surrounding the fenestration, which is completely closed by the sheet. The tacky surface is exposed through the fenestration, and a release liner is peelably secured thereto. Upon removal of the release liner and draping of the patient, the exposed tacky film is immediately pressed directly onto the area to be incised, and the said area remains fully protected from contamination.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
111 words
A surgical drape comprising, in combination: a. a sheet-like drape body for protectively covering a patient, b. said body having a finite surgical fenestration therein for access through said body by a surgeon to the area of the patient''s skin to be incised, c. the periphery of said fenestration being disposed inwardly from the edges of said drape body, d. transparent penetrable closure means for said fenestration for protecting the said area to be incised from contamination prior to surgery, e. and sterile means forming part of said closure means for securing said drape to the skin of the patient completely and exclusively within the area defined by the fenestration periphery.
Claim 2
Dependent Claim
