Therapeutic heating pad and muff structure

Claim 1

A therapeutic heating pad held in a muff for applying moist heat as a fomentation to a body member inserted therein, said muff comprising a four sided rectangular laminate structure having the following serially juxtapositioned laminas and construction: a fabric, an insulating padding and foil-cloth composite laminas quilted together to form a base sheet; a flexible electrical heating element and a vapor barrier lamina in combination with said base sheet completing said rectangular structure; a pair of adjustable straps each affixed adjacent their ends to said structure positioned parallel and adjacent to two sides of said structure, one end of each strap overlapping said fabric lamina, holding said structure in a tubular muff configuration adjustable to reduce and enlarge the effective diameter of the muff by adjustment of said straps to accomodate a body member; and a flannel moisture pervious liner formed in a tubular configuration detachably connected within said muff along each edge thereof; whereby heat generated by said heating element lamina is confined against outward flow through the lamina from said muff by said batting and fabric laminas and is directed by said foil-cloth composite lamina inwardly to uniformly heat said flannel liner through said vapor barrier lamina producing a moist heat fomenting said body member inserted within said muff.
