Method for the application of a layer remaining permanently adhesive onto the inside of a breast prosthesis
View Patent ↗A system is provided for application of a layer permanently adhering to the inside of a breast prosthesis formed as a shell-shaped body made from a soft-elastic material, in which a two-component silicone rubber forming the adhesive layer is injected into a mold prior to curing of the body and then cured together with the body. Alternatively, the two-component silicone rubber forming the adhesive layer is first cured in a shell, with the shell then being applied to the body in a mold and then cured again with the body. In a third alternative, the adhesive layer is cured while being joined to a carrier film, with the carrier film then being adhered to the prosthesis sheath which is then filled with addition-vulcanizing two-component silicone rubber and cured in a mold.
1. A method for producing a breast prosthesis with a single adhesive layer at its inside, said single adhesive layer remaining permanently adhesive, comprising the steps of
forming a prosthesis sheath from plastic film material by welding the same at a circumferential edge,
applying a single two-component silicone rubber mass layer directly to an exterior portion of said thus-formed prosthesis sheath,
after applying the soft elastic material to the sheath portion, then filling a soft-elastic material into said prosthesis sheath, and
after filling the soft elastic material into the sheath, then curing said soft-elastic material within said prosthesis sheath together with said single two-component silicone rubber mass layer in a shell-shaped mold.
2. A method in accordance with claim 1 , wherein said soft-elastic material which is filled into said prosthesis sheath is made of a soft-elastically set addition-vulcanizing two-component silicone rubber mass.
3. A method according to claim 2 , wherein said single two-component rubber mass layer is directly applied to the exterior portion of said thus-formed prosthesis sheath without agency of a carrier layer.
4. A method according to claim 1 , wherein said single two-component rubber mass layer is directly applied to the exterior portion of said thus-formed prosthesis sheath without agency of a carrier layer.
5. A method for producing a breast prosthesis with a single adhesive layer at its inside, said single adhesive layer remaining permanently adhesive, comprising the steps of
applying a single two-component silicone rubber mass layer directly to a plastic film material,
after applying and curing the two-component silicone rubber mass to the plastic film material, then forming a prosthesis sheath from said plastic film material by welding the same at a circumferential edge,
after forming the prosthesis sheath, then filling a soft-elastic material into said thus-formed prosthesis sheath, and
after filling the soft elastic material into the sheath, then curing said soft-elastic material within said prosthesis sheath in a shell-shaped mold.
6. A method according to claim 5 , wherein said step of applying a two-component silicone rubber mass to said plastic film material comprises application of said two-component silicone rubber mass to the whole surface of said plastic film material which is intended to form the inside portion of the breast prosthesis.
7. A method according to claim 6 , wherein said single two-component rubber mass layer is directly applied to the plastic film material without agency of a carrier layer.
8. A method in accordance with claim 5 , wherein said soft-elastic material which is filled into said prosthesis sheath is made of a soft-elastically set addition-vulcanizing two-component silicone rubber mass.
9. A method according to claim 8 , wherein said single two-component rubber mass layer is directly applied to the plastic film material without agency of a carrier layer.
10. A method according to claim 5 , wherein said single two-component rubber mass layer is directly applied to the plastic film material without agency of a carrier layer.
