Title
(EN) PROSTHETIC LINER AND METHOD FOR MAKING THE SAME
(FR) DOUBLURE PROTHÉTIQUE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN)
A method for making a prosthetic liner (100) includes the steps of providing a textile sleeve (102), applying an uncured silicone material onto an inner surface of the textile sleeve (102) and impregnating interstices of a high-density knit structure of the textile sleeve (102). The silicone material is a fast-cure silicone material arranged to cure faster than conventional silicone material. The silicone material is preferably limited to the inner surface of the textile sleeve (102), whereas the outer surface is devoid of the silicone material. The silicone defines an inner layer (101) forming the interior surface of the liner (100), and the outer surface of the textile sleeve (102) forms the exterior surface of the liner (100). A thickness of the liner (100) from the interior surface of the liner (100) to the inner surface of the textile layer (102) consists of the silicone of the inner layer (101).

La présente invention concerne un procédé de fabrication d’une doublure prothétique (100) qui comprend les étapes de fourniture d’un manchon textile (102), application d’un matériau de silicone non durci sur une surface interne du manchon textile (102) et imprégnation des interstices d’une structure tricotée à haute densité du manchon textile (102). Le matériau de silicone est un matériau de silicone à durcissement rapide conçu pour durcir plus rapidement qu’un matériau de silicone conventionnel. Le matériau de silicone est de préférence limité à la surface interne du manchon textile (102), tandis que la surface externe est dépourvue du matériau de silicone. La silicone définit une couche interne (101) formant la surface intérieure de la doublure (100), et la surface externe du manchon textile (102) forme la surface extérieure de la doublure (100). Une épaisseur de la doublure (100) de la surface intérieure de la doublure (100) à la surface interne de la couche textile (102) est constituée de la silicone de la couche interne (101).
