The invention relates to an autoinjector comprising a lower body (10) that receives a barrel, said barrel containing fluid product and comprising a plunger and a needle, such as a pre-filled syringe (A). The autoinjector also comprises a central body (1) secured to the lower body (10) and an actuator sleeve (11) provided with a contact end intended to come into contact with the user's body. The actuator sleeve (11) can be moved between a projecting position and an actuation position, said actuator sleeve (11) occupying the projecting position prior to and following actuation of the autoinjector. Injection means (5, 8) are provided to inject the fluid product through the needle when the needle is in an injection position in which it is inserted into the user's body. The autoinjector further comprises a barrel movement device (2, 4, 9) for moving the needle into the injection position, said barrel movement device triggering the aforementioned injection means only after the needle has reached the injection position. |
