Abstract
Abstract A surgical pad for draping over a patient to hold various articles thereon is manufactured of a flexible sheet of nonporous plastic material. The bottom side of the sheet has a roughened, friction gripping surface with portions pressed upwardly to define projections on the upper surface which may engage articles placed on the sheet. The projections define cavities open at the bottom of the sheet which are surrounded by rings projecting downwardly from the sheet to serve as mechanical gripping means and as suction cups for holding the pad in place on the patient.
