EXTERNAL PROSTHESIS WITH MAGNETIC FIELD

摘要

An external prosthesis (10) with a magnetically transmissive/receptive layer (16) for use with an internal prosthesis attachable to the stump of a residual limb. The external prosthesis (10) comprises a synthetic body member having a concave socket (12) formed at an end thereof. The socket (12) is sized to receive the stump of a residual limb with an internal prosthesis installed. The socket (12) has disposed on its concave external surface (14) a magnetically transmissive/receptive layer (16). Magnetic attraction between the magnetically transmissive/receptive layer (16) and the magnetically attractive internal prosthesis will insure a secure and non-slip installation of the external prosthesis (10) on the residual limb of the user. The external prosthesis (10) may further comprise a pressure deformable layer disposed atop, beneath or within the magnetically transmissive/receptive layer (16), or provide alternating pressure through breaking and re-establishing magnetic attraction as would occur through interrupting an electromagnetic force to its recipient.
