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 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) a shear member (19) disposed in said reservoir (16) and a fluid disposed in said reservoir (16) around said shear member (19) one of said reservoir (16) and said shear member (19) being mounted rotating in said body (1) and the other of said reservoir (16) and said shear member (19) being fixed in rotation the rotation of one relative to the other being braked by the shearing of said fluid contained in said reservoir (16) said reservoir (16) comprising projections (165) on the inner surface of same and said shear member (19) comprising projections (195) on the outer surface of same said projections (165 195) generating restrictions to the flow of the fluid.
