Abstract
Abstract The invention relates to a method for producing a breast prosthesis in which a two-component addition cross-linkable soft elastic silicone rubber composition is introduced into a synthetic resin film constituting the inside and the outside of the prosthesis. The synthetic resin film filled with the as yet uncross-linked silicone rubber composition is arranged in a mold and silicone rubber composition is caused to cross-link with the development of heat. In order to improve upon the known method for the production of breast prostheses that the holding members to be attached may simply be arranged on the breast prosthesis and that the finished breast prosthesis has a neat appearance, in accordance with the invention at least one holding element, preferably in the form of an adhesive strip, is applied to the inner side of the breast prosthesis, by the activation of a hot-melt adhesive.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
In a method for the production of a breast prosthesis comprising the following steps: introducing a two-component addition cross-linkable soft elastic silicone rubber composition into a synthetic resin film, which is to constitute the outer and inner side of the breast prosthesis, introducing the uncross-linked silicone rubber composition into a mold, and cross-linking said silicone-rubber composition by heating said mold and said silicone rubber composition, the improvement comprising the step of: applying to the synthetic resin film constituting the inner side of the breast prosthesis at least one holding element, in the form of an adhesive strip, applied by the activation of a hot-melt adhesive, said hot-melt adhesive being cured during the step of cross-linking said silicone-rubber composition.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The method as claimed in claim 1, wherein the step of applying at least one holding element comprises applying one part of a two-part burr fastener tape.
Claim 4
Dependent Claim
82 words
The method as claimed in claim 1, further comprising the steps of positioning the holding element by means of a suitable cooperating member on a cover of the mold, closing the mold to move the holding element into a desired position on the inner side of the breast prosthesis, activating the hot-melt adhesive by heat provided during the cross-linking of the silicone rubber, and detaching the holding element from the cooperating member by opening the mold after the completion of the cross-linking.
Claim 5
Dependent Claim
20 words
The method as claimed in claim 1, wherein the synthetic resin film employed and furthermore the hot-melt adhesive include polyurethane.
Claim 6
Dependent Claim
36 words
The method as claimed in claim 1, wherein said holding element comprises an adhesive layer, said adhesive layer being adapted to be connected to a complementary support film, on which a permanent tacky layer is applied.
Claim 7
Dependent Claim
35 words
The method as claimed in claim 1 wherein the step of applying the holding element comprises covering over a large area of the inner side of the breast prosthesis with at least one holding element.
Claim 8
Dependent Claim
31 words
The method as claimed in claim 1, wherein the step of applying the holding element comprises covering over a marginal zone of the breast prosthesis with at least one holding element.
Claim 9
Dependent Claim
37 words
The method as claimed in claim 1, wherein the step of applying the at least one holding element comprises bonding a multiplicity of holding elements to a marginal zone of the inner side of the breast prosthesis.
Claim 10
Dependent Claim
37 words
The method as claimed in claim 1, wherein the step of applying the at least one holding element comprises bonding a multiplicity of holding elements to the entire area of the inner side of the breast prosthesis.
