Abstract

A portable support for a breast prosthesis includes in two disclosed embodiments an inflatable bladder of a closed loop configuration with the bladder being made of a flexible material and including valve means whereby the bladder can be selectively inflated and deflated. The bladder in its inflated condition serves to circumferentially and substantially uniformly engage and support the prosthesis without substantially deforming the prosthesis.

Claims

1. The combination of a support and a breast prosthesis wherein the prosthesis is made of a material having generally gelatinous physical behavioral characteristics, said support comprising an inflatable bladder, said bladder being made of a flexible material and including valve means whereby the bladder can be selectively inflated and deflated, the bladder in its inflated condition serving to circumferentially engage, support and substantially maintain the physical configuration of the prosthesis.

2. The combination of claim 1 wherein said bladder is at least slightly deformed in its inflated condition by said prosthesis when in use.

3. The combination of claim 1 wherein said bladder is made from a sheet of flexible air impermeable material having a longitudinal center line, and wherein the material has been folded along the longitudinal center line to define adjacent free edges of the material that are hermetically sealed together to form a closed loop configuration.

4. The combination of claim 1 wherein said bladder in its deflated condition is foldable into a flat orientation.

5. The combination of claim 1 wherein said bladder is made from a sheet of polyvinylchloride.

6. The combination of claim 1 wherein said sheet of polyvinylchloride is a film having the following characteristics:

7. The combination of claim 1 further including membrane means affixed to and supported by said bladder forming a cradle in which said prosthesis can be retained.

8. The combination of claim 7 wherein said membrane means is vacuum formed to conform with a portion of said prosthesis whereby said prosthesis can be uniformly supported by said membrane means.

9. The combination of claim 7 wherein said bladder defines a pair of generally oval-shaped areas and wherein there is a membrane means in each of said oval-shaped areas forming cradles in which a pair of said prosthesis can be retained.
