Abstract
A prosthesis socket material includes a pre-formed tubular sleeve-like reinforcement web of fibers pre-impregnated with an uncured, preferably water activatable, moldable, hardenable resin material, with an integrated prosthesis coupler at one end, the coupler provided with a central aperture. The material is moldable under compression using a one-step compressive molding system. The web of fibers preferably is constituted of a radially compliant tube made of bias braided carbon fibers.
Claims4
A pre-form socket material for molding definitive prosthesis sockets for residual limbs, comprising:
- a web of reinforcement fibers configured as an elongated tube dimensioned to receive a suction sleeve having a sleeve-end fitting including a tension fastener pin receiving opening;
- said web impregnated with a moldable, unhardened resin that is hardenable to a load-bearing rigid state;
- and
- a prosthesis coupler connected to and substantially closing one end of said tube;
- said coupler bondable to said resin so that it is permanently bonded to the resin when the resin is hardened;
- and
- said prosthesis coupler including a centrally located aperture extending through the coupler parallel to the tube length
- said aperture arranged to be aligned with such opening for providing access to such opening by a tension pin element at least during molding of the pre-form socket material over such a suction sleeve.
