Title
(EN) KNIT PROSTHETIC LINER TEXTILE WITH DIFFERENTIATED KNIT FABRIC EXTERIOR
(FR) TEXTILE DE DOUBLURE DE PROTHÈSE TRICOTÉ PRÉSENTANT UN EXTÉRIEUR DE TISSU TRICOTÉ DIFFÉRENCIÉ
Abstract
(EN)
A prosthetic liner (100) for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an outer textile (30) with variable stretch characteristics due to the knit construction and stitching and an interior gel layer (10). The distal region (50) of the liner textile has less stretch than does the intermediate region (70) or proximal region (60) and is stitched together to form a unitary liner. The liner advantageously minimizes a condition referred to as "pistoning" wherein the distal most portion of the residual limb ascends and descends in the lower portion of the socket creating an unhealthy condition for the residual limb.
(FR)
Cette invention concerne une doublure de prothèse destinée à être utilisée avec un ensemble prothèse qui joue le rôle d'interface entre le moignon d'un amputé et l'ensemble emboîture. La doublure de prothèse comprend un textile externe ayant des caractéristiques d'étirement variables en raison de sa construction en tricot et de la couture et une couche de gel intérieure. La région distale du textile de doublure a un étirement moindre que la région intermédiaire ou la région proximale et est cousue de façon à former une doublure d'un seul tenant. La doublure selon l'invention minimise avantageusement un phénomène dit de "pistonnage", où la partie la plus distale du moignon monte et descend dans la partie inférieure de l'emboîture créant une condition néfaste pour le moignon.
