Abstract
An inflatable cushion for elevation of an extremity with respect to a surface supporting the cushion including an inflatable bladder having first and second opposite ends and inner and outer faces. The bladder is equipped with an air inlet for admitting air into the bladder for inflation of the bladder which includes a valve to selectively seal and unseal the air inlet. The first and second ends of the bladder may be fastened together by cooperating fasteners attached to each end. A lining made of a soft absorbent material substantially covers the inner face of the bladder. The bladder may be inflated, wrapped around the extremity and secured by the fasteners so that the bladder completely encircles the extremity. As applied to the extremity, the inner face of the bladder faces inwardly with the lining disposed between the bladder and the extremity and engaging the extremity. An area of the inner face underlying the extremity resiliently deforms under the weight of the extremity such that the weight of the extremity is supported substantially uniformly over the underlying area. The outer face of the bladder faces outwardly with a portion of the outer face engaging the surface.
