Abstract

Cette invention concerne un ensemble seringue hypodermique de sécurité (120) comprenant un fût cylindrique (12A) qui présente une ouverture avant (18A) et une ouverture arrière (26A). Un ensemble piston (28A) est conçu pour coulisser dans le fût. Cet ensemble piston comprend un dispositif de rappel (124) dont l'extrémité constitue la partie avant du piston (122). Un élément de fermeture (132) comporte un ergot central (134) dépassant d'une jupe (136) qui comporte une lèvre extérieure périphérique (138) dont l'intérieur immédiat présente une lèvre interne (140) venant se loger dans un canal correspondant (142) tourné vers la périphérie extérieure de l'extrémité du piston (122). La nervure (138) vient se loger dans la gorge correspondante la plus avant (144) de la face intérieure du fût (12A). En s'emboîtant dans la gorge (142), la lèvre (140) intervient pour désengager l'élément de fermeture de la partie frontale du piston, l'ergot et l'aiguille qui lui est fixée pouvant être rappelés après usage sur une position de verrouillage de sécurité à l'intérieur du fût.
