Abstract

L'invention porte sur un appareil d'injection de liquide dans le corps. L'appareil comprend un corps dans lequel se trouve un espace de stockage de liquide, une extrémité arrière cylindrique ouverte, une extrémité avant pourvue d'un orifice d'injection de liquide, un piston qui injecte le liquide contenu dans l'espace de stockage, vers l'extérieur à travers l'orifice d'injection de liquide. Lorsque le piston est inséré dans l'extrémité arrière du corps, il est déplacé vers l'avant et ajusté dans le corps pour limiter son mouvement vers l'arrière.
