摘要：
An autoinjector having a body (1) receiving a reservoir (S), the reservoir containing fluid and including a piston (P), such as a pre-filled syringe, and stationary in said body (1)； a piston rod (5) that co-operates with the piston (P), the piston rod (5) movable between a primed position and an injection position in which the piston rod has moved the piston so as to inject the fluid into an injection site； and a visual, audible, and/or tactile indicator device for indicating to the user that the autoinjector may be removed from the injection site, the indicator device arranged at the rear end of the body (1), remote from the injection site. The autoinjector includes a retarding device to delay actuating the indicator device relative to the end of injection, the retarding device having an epicyclic gear train having at least one stage, and advantageously two stages.
