Abstract

A medical wrap for the promotion of diabetic and like wound healing generally comprises a multi-layered sheet structure for removable application to a patient'"'"'s foot, said sheet structure having interposed therein an integral bladder; an inlet for fluid inflation of said bladder; and said sheet structure being adapted and said bladder being shaped to produce a non-shearing compressive force in the area of the patient'"'"'s first and fifth metatarsal heads upon fluid inflation of said bladder. The multi-layered sheet structure may comprise a first sheet and a second sheet, said first sheet forming the exterior of said structure and said second sheet forming the interior of said structure, said second sheet being more extensible than said first sheet. A padding layer of ester foam, or the like, may also be incorporated into each sheet.
