Abstract
Abstract Breast prosthesis of an elastic plastic, in particular of silicone rubber composition, having a breast molding corresponding to the female breast and having a contact area adapted to the human body form, which carries an adhesive composition for attachment of the breast prosthesis to the body, which is characterized in that the breast molding comprises on the body-contact side, approximately centered, a recess and an adapter type molding retained therein and rotatable about its vertical median axis, the external wall area of which, turned toward the body, is provided with a coating of an adhesive composition tolerated by the skin. Optionally the breast molding comprises in its upper region a soft core which is highly flexible relative to the cup material.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
Breast prosthesis of an elastic plastic, in particular of the silicone rubber composition, having a breast molding corresponding to the female breast and having a bearing surface adapted to conform to the human body form, and on which an adhesive is applied for attachment of the breast prosthesis to the body, characterized in that the upper portion of the breast molding is in the form of a cup having an approximately centered recess in the direction of the body, in combination with an adapter type molding retained in said recess, said cup being rotatable about said molding on its vertical median axis, and in which the external wall area of said molding, turned toward the body, is provided with a coating of an adhesive composition tolerated by the skin.
Claim 2
Dependent Claim
129 words
Breast prosthesis of an elastic plastic, in particular of the silicone rubber composition, having a breast molding corresponding to the female breast and having a bearing surface adapted to conform to the human body form, and on which an adhesive is applied for attachment of the breast prosthesis to the body, characterized in that the upper portion of the breast molding is in the form of a cup having an approximately centered recess in the direction of the body, in combination with an adapter type molding retained in said recess, said cup being rotatable about said molding on its vertical median axis, and in which the external wall area of said molding, turned toward the body, is provided with a coating of an adhesive composition tolerated by the skin.
Claim 3
Dependent Claim
58 words
Breast prosthesis according to claim 1 in which the recess in the breast molding is cylindrical and is formed about its inner wall with an annular guide profile, and in which said adapter type molding is disk-shaped with a counter-profile integrally formed about its peripheral wall and is engagingly retained by the annular guide profile of said recess.
Claim 4
Dependent Claim
65 words
Breast prosthesis according to claim 2, in which the said recess is formed with an annular wall section leading into the bearing surface of the breast molding, to which wall section an annular groove type section is contiguous, while the adapter type molding comprises at its peripheral wall a counter-profile engaging the annular profile formed by the annular wall section and the annular groove type.
Claim 5
Dependent Claim
23 words
Breast prosthesis according to claims 1, 2 or 3 in combination with a detachable protective sheet covering the said coating of adhesive composition.
Claim 6
Dependent Claim
35 words
Breast prosthesis according to claim 1, in which said breast molding has in its upper part, in particular its nipple region, a soft core which is highly flexible relative to the material of said cup.
Claim 7
Dependent Claim
24 words
Breast prosthesis according to claim 5, in which said highly flexible soft core is formed in the upper front portion of the breast molding.
Claim 8
Dependent Claim
29 words
Breast prosthesis according to claims 5 or 6, in which the highly flexible soft core extends into the lower portion of the breast molding adjacent said adapter type molding.
Claim 9
Dependent Claim
70 words
Breast prosthesis according to claim 7 in which for the formation of the soft core the breast molding has in its upper part in its nipple region an upper wall section formed as a thin skin, and in its lower portion a lower wall section formed as a thin skin, the said two wall sections being connected together to form a bladder type closed cavity containing a silicone gel body.
Claim 10
Dependent Claim
31 words
Breast prosthesis according to claim 8, in which the walls of the breast molding laterally limiting the silicone gel body are formed tapering uniformly and conically toward the upper part thereof.
Claim 11
Dependent Claim
34 words
Breast prosthesis according to claim 9 in which the silicone gel body and the skin type walls of the breast molding are formed to mutually integrate in their contact regions during a vulcanization process.
Claim 12
Dependent Claim
35 words
Breast prosthesis according to claim 8, in which the wall area of the breast molding limiting the cavity is internally lined with a foil preventing penetration of the silicone gel body components through the cup.
Claim 13
Dependent Claim
36 words
Breast prosthesis according to claim 7 in which the said adapter type molding is provided in the region of its upper wall with a soft core of highly flexible material relative to the other molding material.
