Abstract: An inhalation-synchronized fluid dispenser device having a body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially, a metering valve including a valve member assembled on the reservoir for selectively dispensing the fluid. The device also includes an actuator element movable and/or deformable between a non-actuation position and an actuation position; and an inhalation-controlled trigger system including an inhalation-sensitive member deformable and/or movable under the effect of inhaling so as to move and/or deform the actuator element from its non-actuation position towards its actuation position. The actuator element is a locking element that, in its non-actuation position, enables the valve member of the metering valve to move axially in the body together with the reservoir, preventing said metering valve from being actuated when the reservoir is moved axially in the body without inhaling.

Abstract: A method of using a fluid dispenser unit having a reservoir and a piston that slides in the reservoir. The unit includes an extractor head secured to the reservoir to suck fluid to be dispensed into the reservoir, and a spray head assembled on the extractor head to spray the fluid out from the reservoir. The method includes the steps of sucking a fluid to be dispensed into the reservoir through the extractor head; assembling the spray head on the extractor head; and spraying the fluid through the spray head. The step of sucking up a fluid to be dispensed includes a first step of extracting a fluid, such as a solvent, from an extraction reservoir, and a second step of mixing the fluid with a first substance, such as a powder or a lyophilisate, so as to form the fluid to be dispensed.

Abstract: Spraying head having a head body forming a housing having an axis X defining an insertion opening and a substantially flat internal wall through which a central spraying opening extends and a spray nozzle, substantially tubular in shape and axially engaged in the housing of the head body via the insertion opening, the spray nozzle having an inlet that opens into a central internal duct and an external wall defining a central cavity centred on the central spraying opening and a plurality of swirl channels that open tangentially into the central cavity and communicate with the central internal duct. The swirl channels extend axially beneath the central cavity as far as the central internal duct, so as to be in direction communication therewith.

Abstract: Device having a reservoir containing a dose of powder, a head having an orifice, an actuating member displaceable with respect to the head, and an air vent generating a flow of compressed air for delivering the dose of powder into the nostril through the orifice. The air vent has a chamber, formed by a cylinder, and a piston which slides sealingly within the cylinder in order to compress the air contained in the chamber. The device has an insert forming the piston and interacting sealingly, in a rest position, with the reservoir, the insert being axially displaceable with respect to the reservoir between its rest position and an actuation position, in which it no longer interacts sealingly with the reservoir.

Abstract: Pump for dispensing a fluid product, having a piston having a pump chamber and an inlet and outlet valve. The outlet valve has an outlet valve element that slides inside the pump chamber. The pump chamber has a passage so that, at the end of actuation, the outlet valve element collaborates non-sealingly with the passage to open the outlet valve to expel product. The inlet valve has an inlet valve element sliding in a sleeve containing a spring pressing against the inlet valve element and against an end wall of the sleeve. The outlet valve element is formed by a component inserted with the ability to move into the piston, with the interposition of a second spring, the force exerted by the second spring is greater than the force exerted by the spring in the rest position, and less than the force exerted by the spring in the actuated position.

Abstract: An inhalation-synchronized fluid dispenser device having a body with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially in the body, a metering valve including a valve member assembled on the reservoir, an actuator element movable and/or deformable between a non-actuation position in which the metering valve cannot be actuated, and an actuation position in which the metering valve can be actuated; and an inhalation-controlled trigger system including an inhalation-sensitive member deformable and/or movable under the effect of inhaling. The inhalation-sensitive member moves and/or deforms the actuator element from its non-actuation position towards its actuation position. The actuator element is a blocking element that, in the non-actuation position, co-operates firstly with the body and secondly with the reservoir to prevent the reservoir from moving axially in the body.
