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. |
