Abstract
Abstract Discloses a sterile, disposable surgical drape having top and bottom layers sandwiching therebetween a blank of elastic material having equally-spaced holes. The top and bottom layers have aligned square openings exposing thereby said elastic material and holes. Covering tabs having sealing tabs seal the openings in the top layer and lift tabs to facilitate manipulative removal of the covering tabs. The drape is specifically designed and constructed so that tubing, wiring, cables, and the like that are operatively connected to non-sterile equipment may be sterilized and neatly arranged and carried by the spaced holes of the drape.
