Abstract

A wound evacuator comprises a pair of walls which are pushed apart by springs to generate suction in a cavity. A strap coupled to one of the walls includes a plug to close an outlet, a slot cooperating with a peg on the one wall to retain the strap adjacent the one wall and a tab to prevent contact by an individual with the plug upon removal and reinsertion of the plug in the outlet.
