Abstract

Dispositif d'injection automatique (10) comprenant un corps de seringue dans lequel un piston est monté coulissant et une tige de piston (19) configurée pour être mobile entre une configuration de poussée dans laquelle la tige de piston (19) est apte à déplacer le piston dans le corps de seringue entre une position de repos et une position de fin de course et une configuration de libération dans laquelle la tige de piston (19) est apte à se rétracter dans la direction proximale. La tige de piston (19) comprend une partie principale (19D) et une partie de retardement (19P), la partie principale (19D) et la partie de retardement (19P) étant montées mobiles l'une par rapport à l'autre entre une position de poussée dans laquelle la partie principale (19D) et la partie de retardement (19P) sont axialement éloignées et une position de retardement, dans laquelle la partie principale (19D) et la partie de retardement (19P) sont axialement rapprochées.
