Patent ID: 11865249

Abstract:
An inhalation-synchronized fluid dispenser device having a body, a reservoir containing a fluid and a propellant gas that slides axially in the body, a metering valve, a blocking element movable and/or deformable between a non-actuation position and an actuation position, and an inhalation-controlled trigger system that moves and/or deforms the blocking element from the non-actuation position towards the actuation position. The device includes an actuator fastened on the reservoir and having a proximal wall fastened on the end of the reservoir, a body that slides axially past the proximal wall, and a spring arranged between the proximal wall and a distal wall of the body, the body sliding axially past the proximal wall between a rest position and a cocked position in which the spring is compressed, such that on actuation of the trigger system, the compressed spring moves the reservoir so as to actuate the metering valve.
