Sealing sheath for prosthetic liner and related methods

摘要

The sealing sheath is for use with a prosthetic socket and associated liner. The sealing sheath includes a textile tube for surrounding at least a portion of a liner that is configured to wear on a residual limb. An annular seal, e.g. an elastomeric or silicone seal, is positioned adjacent a proximal end of the textile tube and continuously extends from an inside of the textile tube configured to be adjacent the liner, through the textile tube to an outside thereof configured to be adjacent an inside of the prosthetic socket. The annular seal may include a first wing on an inside of the textile tube configured to be adjacent the liner, a second wing on an outside of the textile tube configured to be adjacent an inside of the prosthetic socket, and a base connecting lower ends of the first and second wings to define a v-shaped cross-section of the annular seal.

主权项

1. A method for making a prosthetic device, comprising the steps of:
providing a fabric material; providing male and female molds; placing a section of the fabric material over the male mold; placing the female mold having an annular indent corresponding to a shape of a seal over the male mold and fabric material at a localized area along the fabric material between top and bottom portions of the fabric material; injecting an elastomeric material between the male and female molds at the localized area so as to allow for the elastomeric material to pass through and bridge the fabric to ensure the elastomeric material on both sides of the fabric material at least at the female mold annular indent such that fabric material without the elastomeric material border above and below the localized area.
