Abstract
A portable, lightweight bowel evacuation system is made up of a water bag which is elevated above the patient with a check valve in the delivery line from the water bag into a rectal insertion tube or speculum, a drain line leading from the speculum includes a disposable valve member for selectively opening and closing the drain line, and one or more pressurizing members in the form of manual squeeze bulbs are provided to simultaneously open the check valve for delivery of water from the water bag through the speculum and close the drain valve while the check valve is open and further is open to simultaneously close the check valve when the drain is opened. In a modified form, a flow control valve in communication with a source of air under pressure takes the place of the manual squeeze bulb to control opening and closing of the valve members.
