Abstract

L'invention porte sur une seringue contenant un médicament (150) et comportant un premier (166) et un second (210) éléments tubulaires, un ensemble tige de piston (154), une aiguille distale (176) et une bague (186). Le premier élément tubulaire (166) comprend des extrémités distale et proximale. Il inclut également un élément coulissant (171) qui s'insère à l'intérieur et qui est conçu pour contenir une quantité de médicament prérempli dans une partie distale à cet élément. L'ensemble tige de piston comporte une tige de piston (154) montée de façon réciproque et adaptée pour toucher l'élément coulissant (171) à travers l'extrémité proximale du premier élément tubulaire (166). L'aiguille (176) comprend des extrémités distale et proximale et un embout (174) monté près de l'extrémité distale du premier élément tubulaire (166). Elle (176) inclut également une pointe d'aiguille distale (179) à son extrémité distale. L'extrémité proximale de l'aiguille est conçue pour communiquer librement avec le médicament contenu dans une partie distale de l'élément coulissant (171). La bague (186) est reliée de façon fonctionnelle à l'extrémité distale du premier élément tubulaire (166), et le second élément tubulaire (210) est placé autour du premier élément (166) et de la bague (186). Le second élément tubulaire (210) inclut des extrémités distale et proximale et est conçu pour toucher de façon coulissante la bague (186). Il se déplace longitudinalement sur le premier élément tubulaire (166) et la bague (186) entre une position rétractée, dans laquelle la pointe d'aiguille distale (179) est exposée, et une position allongée dans laquelle la pointe d'aiguille distale (179) est protégée. Il (210) comprend également à son extrémité distale une section effilée (216). Le diamètre externe de l'extrémité distale de la section effilée (216) est essentiellement inférieur au diamètre externe de l'extrémité proximale du second élément tubulaire (210). Lorsque ce dernier (210) est en position rétractée, son extrémité distale est près de l'embout d'aiguille (174) et de l'extrémité distale du premier élément tubulaire (166).
