"The Shirley wound drain or sump drain is a suction drain with an intake tube that provides air to the bottom of the main tube. This allows a continuous flow of suction so that the tube doesn't get blocked. The Shirley drain is a double-lumen drainage tube intended to aspirate efficiently the contents of a fresh surgical wound. It removes the blood oozing from the walls of the wound cavity before it clots."@en . . . "1018"^^ . . . . . . . "Shirley drain"@en .
