933,052. Deformity appliances. W. O. KAUSCH. March 29, 1962 [June 1, 1961], No. 12126/62. Class 81 (2). [Also in Group V] An artificial breast comprises a flexible seamless concavo-convex envelope 19 containing liquid 37 and a foam or flock material backing 30 nested in the concave wall 21 of the envelope. A fluid, e.g. a self-sealing liquid, aqueous solution of cellulose, a glycol cellulose mixture, rubber cement and powdered wood or aluminium oxide, is introduced by a hypodermic needle through a rubber plug 17 having a selfsealing opening, residual air being withdrawn through a hypodermic needle. The backing comprises a shaped block 30 of synthetic foam material, e.g. polyurethane, which is seated around the periphery only of the concave wall of the envelope by an adhesive. Alternatively, a concavo-convex backing of rayon flock may be affixed to the concave wall. The envelope is moulded, with the plug 17 positioned on a pin 16, from plasticized polyvinyl chloride with a silicone, between male and female dies 13, 15 in a rotary casting oven at 400-500 F. the backing being fixed subsequently. The prosthesis is covered in nylon or silk material and secured on the body by a brassiere.
