Abstract: 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.
