A device for expelling fluid from a pre-filled vial includes a hollow needle that is axially mounted on a syringe body. A guard, also mounted on the syringe body, is moveable between a first position wherein it is held to expose a distal portion of the needle and a second position wherein, after being released, it covers the distal portion. In operation, the vial is engaged in fluid communication with the needle, and it is then advanced on the syringe body. During this advancement, fluid is expelled from the vial through the needle, and the vial releases the guard for its movement from the first to the second position.

L'invention porte sur le dispositif d'éjection d'un fluide contenu dans une fiole préremplie, comportant une aiguille montée axialement sur le corps de la seringue, et une garde également montée sur le corps de la seringue et mobile entre une première position où elle retenue et laisse exposée la pointe de l'aiguille, et une deuxième position où après avoir été libérée, elle recouvre la pointe de l'aiguille. En marche, la fiole s'avance vers le corps de la seringue et communique avec l'aiguille. Son avance expulse le fluide via l'aiguille et libère la garde qui passe de la première position à la deuxième.
