Abstract
A surgical drape is described which includes a pouch having one embodiment a one-piece construction and formed with a single seam. An edge of the pouch may be extended to create a concave surface to control and contain fluids during a surgical procedure. Once formed or shaped into the pouch and the edge sealed, the sheet has a front portion, a back portion, an upper back edge in the back portion for placement relatively near the surgical site, and an upper front edge on the front portion, which in the final configuration, is located away from the upper back edge. The upper back edge and the upper front edge together define the opening in the pouch having a circumference. Additionally, the length of the upper front edge is preferably greater than the length of the upper back edge.
Claims27
An arthroscopic pouch for use with a surgical drape, the pouch comprising:
- a single folded sheet of flexible fluid impermeable material having a front portion with a central region and an upper front edge having a length furthest away from a patient when disposed on a patient, the central region of said front portion having a first fenestration for receiving a leg, a back portion with a central portion and an upper back edge having a length nearest the patient when disposed on a patient, the central region of said back portion having a second fenestration for receiving the leg, and only a single seam formed on said back portion by joining edges of said folded sheet to form the pouch wherein the single folded sheet formed with the single seam in a folded shape has a fold and at least a first outer perimeter side defined by the seam, a second outer perimeter side defined by the fold, a third outer perimeter side substantially opposite the first side and a fourth outer perimeter side substantially opposite the second side, wherein the first and second sides join to form an angle less than 90.degree. and the first and fourth sides join to form an angle less than 90.degree. and wherein the fourth side defines the upper back edge, and
- a layer of adhesive applied to the back portion of said folded sheet adjacent the upper back edge wherein the length of the upper back edge of said back portion is defined by said layer of adhesive such that the length of the upper front edge is greater in length than the length of the fourth outer perimeter side and greater than the length of the upper back edge.
An arthroscopic pouch for use with a surgical drape, the pouch comprising:
- a single folded sheet of flexible fluid impermeable material having a fold and having first and second edges joined in a seam,
- at least two spaced apart adhesive portions applied to the sheet for attachment to the surgical drape, and a front portion furthest away from a patient and a back portion nearest the patient, said front portion having a front fenestration for receiving an appendage of the patient, said back portion having a back fenestration for receiving the appendage of the patient wherein the back fenestration for receiving an appendage is substantially surrounded by said first adhesive portion and said second adhesive portion is applied spaced apart from said first adhesive portion on said sheet, and wherein the seam joining the edges of said folded sheet to form the pouch is positioned within the second adhesive portion and wherein the single folded sheet formed with the single seam in a folded shape has at least a first outer perimeter side defined by the seam, a second outer perimeter side defined by the fold, a third outer perimeter side substantially opposite the first side and a fourth outer perimeter side substantially opposite the second side, wherein the first and second sides join to form an angle less than 90.degree. and the first and fourth sides join to form an angle less than 90.degree. and wherein the fourth side defines the upper back edge.
A method of manufacturing an arthroscopic pouch for use with a surgical drape comprising the steps of:
- selecting a single flexible sheet of fluid impermeable material with a top edge, a bottom edge and two opposite edges with respect to a center line of said sheet,
- folding said top edge creating a channel defined by the sheet and the folded portion of said top edge for receiving a draw wire,
- joining said folded portion of said top edge to said sheet enclosing a portion of said channel,
- forming a first fenestration along said center line for receiving a limb,
- applying a fenestration covering over said first fenestration,
- folding said sheet along said center line,
- removing a portion of said folded sheet along at least one of said overlapping bottom edge, top edge, and two opposite edges,
- joining the overlapping bottom edges of said sheet to form the only seam in said fluid collection pouch,
- forming a second fenestration along said bottom edge for receiving a limb,
- inserting a draw wire into said channel along the length of said top edge,
- and applying adhesive along both sides of said only seam of said pouch for attachment to the surgical drape.
A method of manufacturing an arthroscopic pouch to be used for collecting fluids at a surgical site, the method comprising the steps of:
- selecting a sheet of flexible fluid impermeable material with a top portion and top edge, a bottom portion and a bottom edge and first and second substantially opposite side portions and side edges,
- folding said sheet substantially along an approximate center line of said sheet forming a fold having a given length and bringing said side edges together in overlapping position,
- removing at least a first angled portion from one of said top, bottom and side portions of said sheet, said first removed angled portion of said sheet consisting of an area along a separated edge leaving one of said other edges adjacent the separated edge shorter in length than the separated edge while leaving the fold length substantially unchanged, and
- sealing one of said folded top and bottom edges of said folded sheet to form a fluid collection pouch.
