Definitions
- FIG. 1 is a front and top perspective view of a compound prosthesis embodying the present invention
- FIG. 4 is a greatly enlarged fragmentary view within the area encircled at 4 in FIG. 3, showing individual cells filled with a liquid;
- the open-cell foam of core 12 absorbs the liquid added and though the liquid moves easily within the envelope and sponge, the sponge tends to maintain the relative contour of the prosthesis as the wearer changes position.
- the core gives a relatively stable shape to the prosthesis. This is also true, even though envelope 14 is not completely filled with liquid, and if the envelope should be ruptured the sponge sucks in and holds the liquid and thus prevents complete collapse.
- Bonding outer layer 16 to the envelope around the opening therein leaves a free portion 20 of the envelope which, like a hinged cover or flap, can swing down to cover the opening.
- the flap 20 covers the filler tube so that the entire external surface of the prosthesis is a layer of open-cell foam.
- a layer having a thickness of the order of l to 2 millimeters, and preferably not over 2 millimeters, has
- the slits thus do not cut transversely across the core, so as to disconnect the apex of the core from the base, and the several segments of the core, thus individually intact from base to apex, result in the slitted core retaining its memory through these segments, so as to tend inherently to return to its original form when deformed therefrom.
- the contained liquid flows partly via the pores of the core material and partly via the slits 30 and 31 to move with external pressures, or relief thereof, or of change of position, to simulate natural movement and mobility.
