Abstract

Abstract A generally T-shaped disposable surgical drape for use with an operating table having armboards extending laterally from the upper portion thereof, this drape comprising novel flap construction to provide more secure sterile field. Drape comprises an elongated lower or body portion for covering the body of the patient and the lower end of the operating table, which body portion may have a fenestration opening therein, and a transversely disposed upper or crossarm portion integral with the upper end of the body portion, for covering the patient''s arms, while the same are extended on and supported by the armboards. In accordance with a main feature of the invention, a pair of generally rectangular armboard flaps are provided, the top edges of which are integral with the bottom edge of the upper or crossarm portion of the drape, on opposite sides thereof, which armboard flaps are detached from any other portion of the drape, these draping over the armboards to each lie in a generally vertical plane substantially perpendicular to the plane of the operating table, and to overlie a portion of the body portion of the drape, when the drape is positioned over a patient. In accordance with one preferred aspect of the invention, body portion is modified by two generally rectangular body flaps integral with the long side edges of the body portion of the drape but detached from the crossarm portion, these body flaps providing improved coverage in use, being draped over the sides of the operating table to lie in a generally vertical plane on either side thereof when the drape is positioned over a patient. The drape in general, and the armboard flaps and body flaps in particular, are dimensioned to provide overlap between the armboard flap and the lower or body portion of the drape and/or the adjacent body flap (if present), thus providing a more effective barrier to bacterial migration from the non-sterile regions of and surrounding the patient, especially in the vicinity of the armboards, to the sterile field of the operation.

Claim 2
Dependent Claim 148 words
A generally T-shaped surgical drape for use on an operating table having a laterally extending board for supporting a patient''s arm, said drape comprising an elongated, generally rectangular body portion having top and bottom ends and a pair of side edges, an elongated rectangular crossarm portion having top and bottom ends and side edges, said crossarm portion being disposed transversely of said body portion, the top end of said body portion being shorter than and integral with the bottom end of said crossarm portion, and an armboard flap having top and bottom ends and side edges, said armboard flap extending along the bottom end of said crossarm portion from a side thereof to a point overlying said body portion, the top end of said armboard flap being integral with the bottom end of said crossarm portion, said armboard flap being substantially free of attachment to said body portion.
Claim 3
Dependent Claim 14 words
The surgical drape of claim 1, which comprises a pair of said armboard flaps.
Claim 4
Dependent Claim 35 words
The surgical drape of claim 2, further comprising a generally rectangular body flap integral with each side edge of said body portion but detached from said crossarm portion and from the armboard flap adjacent thereto.
Claim 5
Dependent Claim 160 words
A generally T-shaped surgical drape for use with an operating table having an armboard extending laterally therefrom, said drape comprising an elongated generally rectangular body portion having top and bottom ends and two side edges; a fenestration opening in said elongated body portion; a transversely disposed generally rectangular crossarm portion having top and bottom ends and two side edges, the bottom end of said crossarm portion being longer than and integral with the top end of said body portion; two generally rectangular body flaps integral with the side edges of said body portion; and two generally rectangular armboard flaps having top and bottom ends and side edges, each said armboard flap extending along the bottom end of said crossarm portion from a side thereof to a point overlying said body portion, the top ends of said armboard flaps being integral with the bottom end of said crossarm portion, said armboard flaps being substantially free of attachment to said body portion.
Claim 6
Dependent Claim 160 words
A generally T-shaped surgical drape for use with an operating table having an armboard extending laterally therefrom, said drape comprising an elongated generally rectangular body portion having top and bottom ends and two side edges; a fenestration opening in said elongated body portion; a transversely disposed generally rectangular crossarm portion having top and bottom ends and two side edges, the bottom end of said crossarm portion being longer than and integral with the top end of said body portion; two generally rectangular body flaps integral with the side edges of said body portion; and two generally rectangular armboard flaps having top and bottom ends and side edges, each said armboard flap extending along the bottom end of said crossarm portion from a side thereof to a point overlying said body portion, the top ends of said armboard flaps being integral with the bottom end of said crossarm portion, said armboard flaps being substantially free of attachment to said body portion.
Claim 7
Dependent Claim 59 words
The surgical drape of claim 4, wherein each said body flap extends the entire length of the edge of the body portion with which said body flap is integral and is free of attachment to the crossarm portion and the adjacent armboard flap, said armboard flap being free of attachment to said body portion and to said body flap.
Claim 8
Dependent Claim 139 words
The surgical drape of claim 5 further comprising a reinforcing panel surrounding said fenestration opening, an instrument receiving pad having a coefficient of friction greater than 1 secured to the top surface of the drape below the lower end of said fenestration opening and a plurality of attachment tabs arranged about said fenestration opening, each said tab having a flexible portion free of the drape, said flexible portion having at least two openings which extend therethrough and through which a tube or a cord may be inserted to secure same thereto, at least one said tab being positioned at the periphery of that end of the reinforcing panel nearest the top end of said body panel, and at least one tab at the periphery at that end of the instrument pad nearest the bottom end of said body panel.
