摘要：
Autoinjector comprising: - a body (1) receiving a reservoir (S), said reservoir (S) containing fluid and comprising a piston (P), such as a pre-filled syringe, - a piston rod (5) adapted to cooperate with the piston (P) of said reservoir (S), said piston rod (5) being displaceable by an injection spring (8) between a loaded position and an injection position in which said piston rod ( 5) has moved the piston (P) of the reservoir (S) to inject the fluid product into an injection site, - a visual, audible and / or tactile indication device to indicate to the user that he can withdraw said autoinjector of said injection site, said autoinjector comprising a delaying system for delaying the actuation of said visual, audible and / or tactile indication device with respect to the end of the injection, said delaying system comprising a reservoir (16) containing a fluid, a piston (19) being disposed in said re reservoir (16), one of said reservoir (16) and said piston (19) being, when actuated by said retarder system, displaceable in translation in said body (1) and the other of said reservoir (16) and said piston (19) being, when actuated by said retarder system, fixed with respect to said body (1), the displacement in translation of one with respect to the other moving said fluid out of said reservoir (16), through at least one flow passage (161； 195), such that said translation displacement is braked. Autoinjecteur comportant: - un corps (1) recevant un réservoir (S), ledit réservoir (S) contenant du produit fluide et comportant un piston (P), tel qu'une seringue pré-remplie, - une tige de piston (5) adaptée à coopérer avec le piston (P) dudit réservoir (S), ladite tige de piston (5) étant déplaçable par un ressort d'injection (8) entre une position chargée et une position d'injection dans laquelle ladite tige de piston (5) a déplacé le piston (P) du réservoir (S) pour injecter le produit fluide dans un site d'injection, - un dispositif
