Abstract
Abstract A device for heating a breast prosthesis which comprises a base on which a liquid filled flexible bag is placed for supporting a breast prothesis. A hinged cover for the base that carries another liquid filled flexible bag on its in surface so that a closing of the cover will cause the under surface of the bag to contact with and conform to the irregular contour of the upper surface of the breast prosthesis. An electric heating element is submerged in the liquid in each bag and a switch and thermostat for the heating elements controls the degreee of heat applied to the breast prothesis.

Claim 1
Independent Claim
194 words
A breast prosthesis heater comprising: (a) a base; (b) a first flexible waterproof thermally conductive and electrically non-conductive material sealed and liquid containing bag supported by said base and adapted to support a breast prosthesis, the upper surface of said bag conforming to the under surface of the prosthesis so as to have uniform contact therewith; (c) a dome-shaped cover for said base and being hingedly connected thereto; (d) a second flexible, waterproof, thermally conductive and electrically non-conductive material, sealed and liquid containing bag secured to the inner surface of said dome-shaped cover, the undersurface of said second bag conforming to the irregular upper surface of the prosthesis when the prosthesis rests on said first bag and said cover is in closed position; whereby substantially the entire exterior surface of the prosthesis is uniformly contacted by both bags; (e) an electric heating element submerged in the liquid in each bag for heating said liquids; and (f) an electric insulated cord interconnecting said heating elements with an electric outlet and having temperature control means for controlling the heat delivered by said heating elements to maintain the breast prothesis at the temperature of the human body.
