Abstract
Abstract The tubular surgical drape is adapted to cover a patient extremity and includes a pull sleeve concentrically rolled with a tubular stockinette to form a doughnut-shaped roll. The pull sleeve surrounds the outer wall of the doughnut-shaped roll and applies an unrolling force in a uniform manner completely around the rolled stockinette so as to provide for rapid and uniform application of the tubular stockinette to the patient extremity. Rupturable means, in the form of one or more tear lines, is provided along the length of the pull sleeve to provide for easy separation while the pull sleeve is being drawn along the patient extremity to unroll and apply the stockinette thereto.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
A tubular surgical drape adapted to be drawn onto and surround a patient extremity and comprising (a) a tubular stockinette having inner and outer walls, an open end and a closed end, said tubular stockinette having the open end curled outwardly from the center thereof and rolled toward the closed end, and (b) a pull sleeve concentrically rolled with said tubular stockinette, said pull sleeve including rupturable means extending longitudinally and substantially throughout the length thereof so that said pull sleeve will readily separate longitudinally when said pull sleeve is being drawn along the patient extremity to unroll and apply the tubular stockinette thereto.
Claim 2
Dependent Claim
104 words
A tubular surgical drape adapted to be drawn onto and surround a patient extremity and comprising (a) a tubular stockinette having inner and outer walls, an open end and a closed end, said tubular stockinette having the open end curled outwardly from the center thereof and rolled toward the closed end, and (b) a pull sleeve concentrically rolled with said tubular stockinette, said pull sleeve including rupturable means extending longitudinally and substantially throughout the length thereof so that said pull sleeve will readily separate longitudinally when said pull sleeve is being drawn along the patient extremity to unroll and apply the tubular stockinette thereto.
Claim 3
Dependent Claim
20 words
A tubular surgical drape according to claim 1 wherein said rupturable means extends along opposed sides of said pull sleeve.
Claim 4
Dependent Claim
38 words
A tubular surgical drape according to claim 1 wherein said pull sleeve comprises thin tubular material and wherein said pull sleeve includes a plurality of perforations spaced along the length thereof to facilitate sterilization of said surgical drape.
Claim 5
Dependent Claim
32 words
A tubular surgical drape according to claim 1 wherein said pull sleeve rupturable means comprises periodically interrupted cut lines extending longitudinally along opposite sides of said pull sleeve and forming tear lines.
Claim 6
Dependent Claim
17 words
A tubular surgical drape according to claim 1 wherein said tubular stockinette comprises a seamless knit fabric.
Claim 7
Dependent Claim
66 words
A tubular surgical drape according to claim 1 wherein said concentrically rolled tubular stockinette and pull sleeve form a doughnutshaped roll with the closed end of said tubular stockinette extending across one end portion of said doughnut-shaped roll, and wherein said pull sleeve is wrapped around the outer surface of said doughnut-shaped roll with the free end being tucked into the opening in said doughnut-shaped roll.
Claim 8
Dependent Claim
136 words
A tubular surgical drape adapted to be drawn onto and surround a patient extremity and comprising (a) a tubular stockinette comprising seamless knit fabric having inner and outer walls, an open end and a closed end, said tubular stockinette having the open end curled outwardly from the center thereof and rolled toward the closed end, and (b) a pull sleeve of thin tubular material concentrically rolled with said tubular stockinette, said pull sleeve including rupturable means extending longitudinally along opposed sides thereof for easy separation so that opposite halves of said pull sleeve will separate longitudinally when being drawn along the patient extremity to unroll and apply the tubular stockinette thereto, and said pull sleeve including a plurality of perforations spaced along the length thereof to facilitate sterilization of said surgical drape when in rolled condition.
Claim 9
Dependent Claim
136 words
A tubular surgical drape adapted to be drawn onto and surround a patient extremity and comprising (a) a tubular stockinette comprising seamless knit fabric having inner and outer walls, an open end and a closed end, said tubular stockinette having the open end curled outwardly from the center thereof and rolled toward the closed end, and (b) a pull sleeve of thin tubular material concentrically rolled with said tubular stockinette, said pull sleeve including rupturable means extending longitudinally along opposed sides thereof for easy separation so that opposite halves of said pull sleeve will separate longitudinally when being drawn along the patient extremity to unroll and apply the tubular stockinette thereto, and said pull sleeve including a plurality of perforations spaced along the length thereof to facilitate sterilization of said surgical drape when in rolled condition.
