ABSTRACT:
A vacuum commode is provided in which a bed pan has a sponge rubber seat cushion arranged between the bed pan and the user of the assembly. Inserted between the user and the seat cushion is a hand bulb air pump which is used to create a partial vacuum within the interior of the bed pan. The partial vacuum may be created because the rubber seat and a flexible plastic sheet spread over the patient's lap area provide an air-tight seal between the user and the interior air space of the bed pan. The air pump is used to create a partial vacuum within the interior of the bed pan which causes a suction-like effect therein, thus aiding in the excretion of waste matter from the bowels of the user.
