摘要：
An auto injector comprising: a body (1) receiving a reservoir (S) said reservoir (S) containing fluid product and comprising a piston (P) in the same way as a pre filled syringe a piston rod (5) suitable for cooperating with the piston (P) of said reservoir (S) said piston rod (5) being movable 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) in order to inject the fluid product into an injection site a visual audio and/or tactile indicator device for indicating to the user that he can remove said auto injector from said injection site said auto injector comprising a delay system for delaying the actuation of said visual audio and/or tactile indicator device relative to the end of the injection said delay system comprising a reservoir (16) containing a fluid a piston (19) being disposed in said reservoir (16) one of said reservoir (16) and said piston (19) being movable in translation in said body (1) when said delay system is actuated and the other of said reservoir (16) and said piston (19) being fixed relative to said body (1) when said delay system is actuated the translational movement of one relative to the other moving said fluid out of said reservoir (16) through at least one flow passage (161 195) such that said translational movement is braked said delay system comprising said reservoir (16) containing said fluid said piston (19) a locking key (20) said injection spring (8) a pusher element (17) a support member (6) interposed between said pusher element (17) and said injection spring (8) and said piston rod (5).
