A method for manufacturing a breast prosthesis, wherein the breast prosthesis comprises an outer shell and an airbag inner layer, a cavity is formed inside the outer shell, the outer shell is provided with an opening that is in communication with the cavity, and the airbag inner layer is provided with a gas valve, and wherein the method comprises:
- manufacturing the outer shell using a first mold and a second mold, wherein the second mold is enclosed by the outer shell, and the second mold is made of a soluble material;
- demolding the outer shell and immersing the outer shell in a solution to dissolve the second mold within the outer shell to form the cavity inside the outer shell;
- forming the opening in the outer shell;
- manufacturing the airbag inner layer;
- and
- installing the gas valve on the airbag inner layer to locate the gas valve at the opening of the outer shell upon placing the airbag inner layer into the cavity of the outer shell through the opening.
A breast prosthesis, comprising:
- an outer shell, wherein a cavity is formed inside the outer shell, and the outer shell is provided with an opening that is in communication with the cavity;
- and
- an airbag inner layer located within the cavity, wherein the airbag inner layer is provided with a gas valve for filling the airbag inner layer with gas.
