METHODS AND APPARATUS FOR IMPROVED INTERFACE BETWEEN THE HUMAN BODY AND PROSTHETIC OR SIMILAR DEVICES

摘要

Apparatus is provided to cushion between a prosthetic socket and an amputee's residual limb. A plurality of putty-filled packets are assembled into a liner that, when assembled, provides a generally smooth contact surface toward the residual limb. At least one of the packets has a fluid bladder positioned between the putty material and the socket, and the fluid volume in the bladder can be adjusted to affect the fit of the assembly on the residual limb. Methods of fabrication, fitting, and use of such prosthetic devices are disclosed.

1. Apparatus for cushioning between a prosthetic socket and an amputee's residual limb, including a plurality of liquid-filled packets assembled into a liner, said liner configured to lie generally smoothly between the residual limb and the socket when worn by the amputee, at least one of the packets having a fluid bladder positioned between the putty material and the socket, said bladder being adjustable by varying the amount of fluid within the bladder, the bladder further positioned so that said adjustment affects the fit of the assembly on the residual limb.
