Abstract
Abstract A surgical sheet or drape in the form of a relatively large rectangular panel of nonwoven paper material having a centrally disposed strip of plastic incorporated therein to eliminate strikethrough of body fluids and foreign materials such as lint getting into a wound during a surgical operation, such as a laparotomy. An aperture is formed in the plastic sheet or panel to provide access to the area in which the operation is being conducted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
A surgical drape such as a laparotomy sheet comprising an enlarged panel having an opening disposed centrally therein, and a moistureproof member defining the periphery of the opening to eliminate strikethrough of fluids during a surgical procedure and to eliminate contamination of a wound by lint or other foreign material coming into contact therewith from portions of the drape outwardly of the moistureproof member, said moistureproof member including a strip of flexible plastic material extending completely across said panel and being relatively narrow to separate the enlarged panel into two side panels having the edges thereof secured to the plastic strip.
Claim 2
Dependent Claim
26 words
The structure as defined in claim 2 in which the edges of the side panels overlap and are bonded to the edges of the plastic strip.
Claim 3
Dependent Claim
36 words
The structure as defined in claim 2 wherein said opening in the panel is formed exclusively in said plastic strip with the periphery of the opening being spaced from the overlapping edges of the side panels.
Claim 4
Dependent Claim
51 words
The structure as defined in claim 4 in which the panel is enlarged and substantially rectangular in configuration with the plastic strip extending transversely across the narrow dimension of the panel, said opening in the plastic strip being rectangular with the long dimension thereof paralleling the long dimension of the panel.
Claim 5
Dependent Claim
60 words
The structure as defined in claim 5 wherein the ends of said strip are coextensive with the long edges of the panel with the width of the strip being substantially less than the width of either side panel thereby completely eliminating strikethrough of contaminant fluids while maintaining breathability of the drape to stabilize the condition and temperature of the patient.
Claim 6
Dependent Claim
135 words
A laparotomy sheet comprising a pair of enlarged panels of fabric or nonwoven paper material having sufficient porosity to enable passage of filtered air from one surface to the other and provided with spaced adjacent edges, an elongated strip of flexible plastic material interconnecting the adjacent edges of the panels with the width of the strip of plastic material being relatively small as compared with the total length of the sheet to permit filtered air to pass through a major portion of the sheet while preventing strikethrough of fluids through the plastic strip, and a centrally disposed opening in said plastic strip with the periphery of the opening being at least slightly spaced from the edges of the panels and substantially spaced from the edges of the strip that are not connected to the panels.
