Abstract: A device having a body (10), a reservoir (100) mounted to slide axially relative to the body, a metering valve (200) on the reservoir (100), a blocking element (500), a trigger element (600), an inhalation-controlled trigger system (60) cooperating with the trigger element, an actuating member (800) cooperating with the blocking element, a cover (11) fixed on the body, a push member (810) fastened tot actuating member (800) and mounted to slide axially in the cover, and a spring (850) between the cover and the push member. Before inhalation, the push member is out of contact with the reservoir, such that the force exerted on the push member by the spring is not transmitted to the reservoir, and during inhalation, the push member moves axially with the actuating member so as to come into contact with the reservoir and move it axially in the body to actuate said valve.

Abstract: An autoinjector having a lower body (10; 1010) receiving a reservoir, a piston, a needle, an actuating sleeve (11; 1011) with a contact end to contact the user. The actuating sleeve is displaceable between projected positions and an actuation position, being in a first projected position prior to actuation of the autoinjector. The autoinjector also having an injection device (5, 8; 1005, 1008) and an injection lock. The actuating sleeve is automatically returns to the second projected position when the user removes the autoinjector from his body and is locked in this second projected position. The autoinjector includes an external shell (22; 1022) having a display window for indicating the actuation sequences, at least one display window (221; 1221; 1023) indicating to the user that the injection of the fluid product is finished.

Abstract: An autoinjector having a body (1010; 2010) receiving a reservoir, a piston, a needle, an actuating 5 sleeve (1011;2011) having a contact end to contact the body of the user and displaceable relative to the body between projected positions, in which the actuating sleeve at least partially projects out of the body receiving a reservoir, and an actuation position, in which the actuating sleeve is axially displaced towards the interior of the body receiving a reservoir. The actuating sleeve is in a first projected position prior to actuation of the autoinjector and in a second projected position after actuation of the autoinjector. The actuating sleeve or the body receives a reservoir having a flexible tab adapted to deform laterally relative to the actuating sleeve and/or relative to the body receiving a reservoir when the actuating sleeve is displaced from its first projected position towards its actuation position then from its return actuation position towards its second projected position.
