Abstract

Abstract A surgical drape for use in hip or knee surgery designed to provide a substantially complete seal around an operative site in a one step application and having two main sections integrally connected along a main folding line, with one main section being continuous along the main folding line and the second main section being trifurcated into a median flap connected to the main folding line along a narrow junction and a pair of side flaps connected to the main folding line along wide junctions. The median flap extends substantially equidistantly from the main folding line as the continuous main section extends therefrom in the opposite direction, while the pair of side flaps extend from the main folding line about midway of the median flap. The median flap is provided about its periphery with a strip of surgical adhesive and the pair of side flaps have a strip of surgical adhesive about their edges adjacent the median flap. The trifurcated main section is folded onto the first main continuous section and so folded is positioned, with the median flap under a limb of a patient so that its narrow connecting junction is adjacent the edge of the operative site. Then the median flap and the pair of side flaps are wrapped about the limb so as to provide a substantially complete seal around the operative site with the median flap surrounding one part and the pair of side flaps surrounding the remaining part of the operative site, which site is the only part of the limb left exposed.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 230 words
Surgical drape for use in hip or knee surgery that provides a substantially complete seal around the operative site in a one step application in which said drape has a substantially rectangular shape and is cut from a sheet made from a two-ply bonded fiber nonabsorbent material, said drape comprising: (a) two main sections integrally connected along a main folding line; (b) one main section being continuous along said main folding line; (c) a second main section being trifurcated into a median flap and a pair of side flaps, with said median flap being connected to said main folding line along a narrow junction covered by a strip of surgical adhesive and said pair of side flaps along wide junctions; (d) said median flap being provided about its periphery with a strip of surgical adhesive and said pair of said flaps are each provided with a strip of surgical adhesive about their edges adjacent said median flap; (e) said trifurcated main section being folded onto said first main section in such a way that each of said strips of surgical adhesive faces away from said first main section; (f) said median flap extending substantially equidistantly from said main folding line as said continuous main section extends therefrom in the opposite direction; and (g) said pair of side flaps extending from said main folding line about midway of said median flap.
Claim 2
Dependent Claim 230 words
Surgical drape for use in hip or knee surgery that provides a substantially complete seal around the operative site in a one step application in which said drape has a substantially rectangular shape and is cut from a sheet made from a two-ply bonded fiber nonabsorbent material, said drape comprising: (a) two main sections integrally connected along a main folding line; (b) one main section being continuous along said main folding line; (c) a second main section being trifurcated into a median flap and a pair of side flaps, with said median flap being connected to said main folding line along a narrow junction covered by a strip of surgical adhesive and said pair of side flaps along wide junctions; (d) said median flap being provided about its periphery with a strip of surgical adhesive and said pair of said flaps are each provided with a strip of surgical adhesive about their edges adjacent said median flap; (e) said trifurcated main section being folded onto said first main section in such a way that each of said strips of surgical adhesive faces away from said first main section; (f) said median flap extending substantially equidistantly from said main folding line as said continuous main section extends therefrom in the opposite direction; and (g) said pair of side flaps extending from said main folding line about midway of said median flap.
Claim 3
Dependent Claim 25 words
The surgical drape of claim 1 in which said median flap is formed with a pair of arcuate shoulders adjacent its said narrow connecting junction.
Claim 4
Dependent Claim 25 words
The surgical drape of claim 1 in which said pair of side flaps are each formed with an arcuate segment commencing from said narrow junction.
Claim 5
Dependent Claim 30 words
The surgical drape of claim 1 wherein said median flap is positioned under a limb so that its said narrow connecting junction is adjacent an edge of the operative site.
Claim 6
Dependent Claim 55 words
The surgical drape of claim 4 wherein said median flap is wrapped about said limb adjacent one edge of said operative site and said pair of side flaps are wrapped about said limb adjacent a second edge of said operative site so as to combine to provide a substantially complete seal around said operative site.
