Surgical drape having integral leggings and method of making

Claim 1

A surgical drape having integral leggings therein, comprising: a main sheet having a head end portion, a foot end portion and two side portions where said leggings are located; said main sheet having a fenestration located generally midway between said head and foot end portions and said side portions; said main sheet being inwardly cut from both outside edges toward the center and adjacent said fenestration, each side portion below the cut line being folded inwardly to define a diagonal fold line, the edges of each said folded over side portion defining, together with the unfolded side portion nearer said head end portion, three sides of a generally quadrangular shape; each of said leggings being comprised of a generally quadrangular piece of material attached to said main sheet along said three sides of said shape to define a pocket between said folded over side portion and said piece in which the leg of a patient may be inserted while in the lithotomy position.

Claim 9

A method of making a surgical drape having integral leggings therein, comprising the steps of: providing a main sheet with head and foot end portions defining the longitudinal direction thereof, with a fenestration being located near the center thereof; cutting said main sheet along lines generally transversely of said longitudinal direction and inwardly a predetermined distance at a location between said head end and foot end portions; folding outer side portions nearer the foot end portions of said cut lines inwardly and toward said foot end portion so as to define a generally triangular opening at each side of said main sheet, the edges of each said folded over side portion defining, together with the unfolded side portion nearer said head end portion, three sides of a generally quadrangular shape; adhesively bonding a piece of material to the edges of each of said folded over portions and to the unfolded main sheet adjacent said cut lines to define a pocket between each said folded over portion and piece which provide a pair of integral leggings for draping a patient in the lithotomy position; and applying reinforcing patches having pressure sensitive adhesive thereon at a predetermined point on the third side and at the intersection of the first and second sides of said quadrangular shape to provide additional strength for preventing tearing of said drape during use and to hold said pieces to said main sheet until said adhesive bonding said pieces to said main sheet sets.

Claim 10

A method of making a surgical drape having integral leggings therein, comprising the steps of: providing a main sheet with head and foot end portions defining the longitudinal direction thereof, with a fenestration being located near the center thereof; cutting said main sheet along lines generally transversely of said longitudinal direction and inwardly a predetermined distance at a location between said head end and foot end portions; folding outer side portions nearer the foot end portions of said cut lines inwardly and toward said foot end portion so as to define a generally triangular opening at each side of said main sheet, the edges of each said folded over side portion defining, together with the unfolded side portion nearer said head end portion, three sides of a generally quadrangular shape; adhesively bonding a piece of material to the edges of each of said folded over portions and to the unfolded main sheet adjacent said cut lines to define a pocket between each said folded over portion and piece which provide a pair of integral leggings for draping a patient in the lithotomy position; and applying reinforcing patches having pressure sensitive adhesive thereon at a predetermined point on the third side and at the intersection of the first and second sides of said quadrangular shape to provide additional strength for preventing tearing of said drape during use and to hold said pieces to said main sheet until said adhesive bonding said pieces to said main sheet sets.
