Abstract
Abstract A surgical drape composed of a main sheet of sheet material adapted for use by a patient in the lithotomy position. The surgical drape is fabricated from a main sheet of sheet material which is constructed of sufficient softness and is sufficiently inexpensive to be disposable. The main sheet is formed of a torso section and a bottom section which are interconnected by a pair of side sections. Each side is formed into an enclosed area so as to function as a legging for the patient. The main sheet includes a fenestration centrally located therein with a fenestration strengthening material located entirely about said fenestration. The fenestration strengthening material is to resist tearing and cutting. A layer of non-liquid absorbing protective material is attached to the fenestration strengthening material. A collection container in the form of a flexible walled bag is located adjacent the bottom section. The collection material is adapted to collect blood and solids which are discharged during the medical procedure. A volumetric measuring indicia is carried in the exterior wall of the bag to facilitate the ascertaining of the approximate loss of blood by the patient. In another construction, a second container is provided for collection of fecal matter and a multiplicity of slots, pockets and holders are employed for yieldably retaining a variety of medical implements and supplies.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
250 words
A surgical drape comprising: a main sheet having a torso covering section and a bottom section interconnected by a pair of side sections, said main sheet being constructed of an inherently soft material and sufficiently inexpensive material to be disposable; each said side section forming a substantially enclosed area so as to function as a legging; said main sheet having a fenestration generally centrally located therein; a fenestration strengthening material located entirely about said fenestration and attached to said main sheet, said fenestration strengthening material resisting tearing and cutting of the wall of said fenestration; a layer of protective material attached to both said main sheet and said fenestration strengthening material, said layer of protective material to be nonliquid absorbing; a collection container attached to said layer of protective material adjacent said bottom section, whereby said collection container is adapted to collect blood and solids which are discharged during the medical procedure; said layer of protective material comprising a sheet of plastic; said collection material comprising a flexible walled plastic bag; said flexible walled plastic bag including means to ascertain volumetric measuring of the collected solids and liquids; said means comprising measuring indicia located on said flexible walled bag; a plurality of medical implement and supply holders arranged in fixed spaced apart relationship on each of said side section leggings for releasably retaining surgical implements and medical supplies; and a second container having an open entrance carried immediately behind said first mentioned container and downwardly depending from said bottom section.
