Abstract

Abstract A bilateral fenestrated drape folded in such a manner to eliminate the need for removable paper coverings over the fenestrations. The drape is fan folded in the longitudinal direction and then fan folded transversely to form two stacks of the folds with a bridging or central portion between the stacks. The bridging portion is folded to form flaps which are used to cover the fenestrations.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 220 words
A bilateral, fenestrated, surgical drape comprising a rectangular main sheet having an upper surface and a lower surface, a top edge, a bottom edge and two opposing side edges, two fenestrations spaced apart from each other and spaced inwardly from the side edges of the drape and located along a line parallel to said top and bottom edges, a portion of the main sheet between said line and the top edge and a portion of the main sheet between said line and the bottom edge being fan folded in the longitudinal direction to form two longitudinally folded stacks of folds, the longitudinally folded stacks of folds overlying the upper surface of the drape, and the inner edge of the longitudinally folded stacks lying adjacent the fenestrations, the longitudinally folded stacks being fan folded from the side edges of the drape to form two transversely folded stacks of folds overlying a portion of the upper surface of the main sheet adjacent each of the fenestrations and separated by a central portion of the drape between the transversely folded stacks, the central portion of the drape being folded along fold lines toward a fold line passing through the center of said central portion to form two flaps, the flaps being folded over the lower surface of the drape to cover the fenestrations.
Claim 2
Dependent Claim 220 words
A bilateral, fenestrated, surgical drape comprising a rectangular main sheet having an upper surface and a lower surface, a top edge, a bottom edge and two opposing side edges, two fenestrations spaced apart from each other and spaced inwardly from the side edges of the drape and located along a line parallel to said top and bottom edges, a portion of the main sheet between said line and the top edge and a portion of the main sheet between said line and the bottom edge being fan folded in the longitudinal direction to form two longitudinally folded stacks of folds, the longitudinally folded stacks of folds overlying the upper surface of the drape, and the inner edge of the longitudinally folded stacks lying adjacent the fenestrations, the longitudinally folded stacks being fan folded from the side edges of the drape to form two transversely folded stacks of folds overlying a portion of the upper surface of the main sheet adjacent each of the fenestrations and separated by a central portion of the drape between the transversely folded stacks, the central portion of the drape being folded along fold lines toward a fold line passing through the center of said central portion to form two flaps, the flaps being folded over the lower surface of the drape to cover the fenestrations.
Claim 3
Dependent Claim 30 words
The drape of claim 1 on which there is a reinforcement area surrounding the fenestrations, and the fenestrations are formed in elastic inserts in the reinforcement area of the drape.
Claim 4
Dependent Claim 18 words
The drape of claim 2 in which the flaps are secured over the fenestration with a removable band.
