Abstract

Abstract A surgical drape for use in procedures requiring exposure of both legs and containment of the perineum comprised of a flexible draping material, a second smaller sheet of foam/film laminate bonded to the first sheet with two elongated fenestrations formed through both layers of sheets. The elongated fenestrations open onto one end of the drape and extend toward the middle of the drape in alignment with the sides and with each other and spaced apart to receive the legs of a patient. The drape is folded to form a compact unit for storage and sterilization and in a manner that unfolding and application of the drape to the patient can be accomplished with a minimum chance of contamination.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 208 words
A disposable surgical drape for bilateral leg surgery comprising: (a) a nonwoven sheet having side edges and end edges, the sheet having two substantially parallel fenestrations defining operative sites through each of which a leg of a patient may be exposed, said fenestrations having an open end and a closed end, said open end opening onto one end edge and said fenestrations extending longitudinally toward the middle of the sheet substantially parallel to the side edges with said closed ends being shaped to accomodate the patient's legs, the fenestrations being spaced apart forming a central flap that conforms to the spacing between a patient's legs; (b) an absorbent, fluid impervious laminate attached to one surface of the nonwoven sheet, the laminate substantially surrounding the fenestrations in the nonwoven sheet, the laminate having two fenestrations conforming to and aligned with the two fenestrations in the sheet; (c) tacky pressure sensitive adhesive on the surface of the nonwoven sheet opposite the laminate adjacent the edges and closed end of each said fenestrations; and (d) removable adherent release strips covering the pressure sensitive adhesive whereby, once said drape is in use, both the patient's legs may be exposed through said fenestrations while the perineal area is covered by said central flap.
Claim 2
Dependent Claim 208 words
A disposable surgical drape for bilateral leg surgery comprising: (a) a nonwoven sheet having side edges and end edges, the sheet having two substantially parallel fenestrations defining operative sites through each of which a leg of a patient may be exposed, said fenestrations having an open end and a closed end, said open end opening onto one end edge and said fenestrations extending longitudinally toward the middle of the sheet substantially parallel to the side edges with said closed ends being shaped to accomodate the patient's legs, the fenestrations being spaced apart forming a central flap that conforms to the spacing between a patient's legs; (b) an absorbent, fluid impervious laminate attached to one surface of the nonwoven sheet, the laminate substantially surrounding the fenestrations in the nonwoven sheet, the laminate having two fenestrations conforming to and aligned with the two fenestrations in the sheet; (c) tacky pressure sensitive adhesive on the surface of the nonwoven sheet opposite the laminate adjacent the edges and closed end of each said fenestrations; and (d) removable adherent release strips covering the pressure sensitive adhesive whereby, once said drape is in use, both the patient's legs may be exposed through said fenestrations while the perineal area is covered by said central flap.
Claim 3
Dependent Claim 67 words
The drape of claim 1 wherein each fenestration opening has a circular shape at the innermost end from said end edge of the sheet with a slit extending from the circular element of each fenestration connecting it to said end edge of the sheet, the circular shape opening defining the circumference of the leg to provide a closer fit of the drape with less bulk and overlap.
