Abstract
Abstract A surgical equipment tray inexpensively fabricated from a sheet of rigid plastic material. The tray has an absorbent, lint-free surface which (1) absorbs fluids, (2) provides a nonskid instrument surface, and (3) attenuates the noises associated with handling instruments on the tray. Longitudinal ridges and grooves may be included in the base of the tray to provide rigidity to the tray and elevate or expose the instruments for easy access.
