Abstract
An autoinjector having a body (1) receiving a reservoir (S) containing fluid and including a piston (P), such as a pre-filled syringe; a piston rod (5) that co-operates with the piston (P), the piston rod (5) being movable by an injection spring (8) between a primed position and an injection position in which the piston rod (5) has moved the piston (P) of the reservoir (S) so as to inject the fluid into an injection site; and an indicator device for indicating to the user that the autoinjector may be removed from said injection site. The autoinjector also includes a retarding system to delay the end of actuating the indicator device relative to the end of injection, the indicator device generating a noise while being actuated, the noise being generated until the end of actuating the indicator device.
