A postural drainage device for supporting a patient comfortably in a position in which mucus and other matter can drain by gravity from his respiratory system. The invention includes a first embodiment which is portable and collapsible and assumes a substantially A-shape when in use. The two side members of the A-shape are pivotally mounted to each other adjacent the apex of the A-shape and provided with an adjustable knee support mounted on one of the side members, a pair of spaced-apart hand grips positioned adjacent the apex of the A-shape, and a pair of adjustable shoulder supports mounted in a spaced-apart relationship on the other side member with a hole cut through that side member into the interior of the A-shape providing access to a tray placed on the transverse member of the A-shape. The hand grips extend slightly above the apex of the A-shape to help maintain the patient therebetween on the apex. The patient's knees are supported on the knee support, his mid-section on the apex of the A-shape between the hand grips, and his shoulders on the spaced-apart shoulder supports with his head extending downwardly therebetween through the hole. In a second embodiment, leaf members corresponding to the two side members of the A-shaped embodiment are pivotally mounted to a main body and individually moved by respective piston-cylinder arrangements.
