Abstract

Abstract An improved surgical extremity drape (4) which circumferentially envelops the injured limb creating a self enclosed system through which irrigation and debridement is performed. The drape (4) isolates the injured limb from the remainder of the body as well as the surgical team in order to create a fluid splash barrier to prevent the splash or spill of contaminated blood or surgical irrigants. The drape (4) is made in a atubular form of a clear polyethylene fluid impervious, film (5) with a closed distal end (20) and an open proximal end (10). The limb is placed inside of the drape through a fenestrated liquid resistant rubber stretch seal (12) which prevents the leakage of surgical irrigants. A resealable slit (8) is present to allow access to the extremity for wound care or bone fracture fixation prior to or after irrigation and debridement. In addition, perforated hand fenestrations (16) are provided to allow passage of a gloved hand in order to manipulate the limb during irrigation. Perforated irrigation nozzel fenestrations (18) are provided to allow passage of the irrigation nozzel inside of the drape. A drainage plug (6) is provided for drainage of blood and contaminated irrigation fluids.
