摘要： A fluid dispenser head (T) including a spray wall (26) that is perforated with a network of holes (O) through which the fluid under pressure passes so as to be sprayed in small droplets;
the dispenser head being characterized in that the network of holes (O) comprises at least two series of holes (O), with the holes (O) of a given series presenting holes that are substantially identical in size, and with the holes (O) of different series presenting holes that are different in size, such that one series of holes (O) generates a spray of small droplets with droplet sizes that define a first Gaussian distribution, while another series of holes (O) generates a spray of small droplets with droplet sizes that define a second Gaussian distribution that is offset relative to the first Gaussian distribution, thus producing a complex spray having at least two distinct Gaussian distributions.-

摘要： A method of analyzing a spray generated by a spray device for spraying pharmaceutical fluid, including providing a spray head of a spray device for spraying pharmaceutical fluid, the spray head including a spray orifice; causing a test fluid to pass through the spray head towards the spray orifice, the test fluid being air at a temperature that is different from ambient temperature; displaying, by strioscopy, the flow of test fluid leaving the spray orifice; and analyzing the display of the test-fluid flow so as to determine whether or not the test-fluid spray coming from the spray head complies with predetermined specifications. The cycle time for analyzing one spray head is less than 1.5 seconds, advantageously less than 1 second.

摘要： A fluid dispenser device including a body; a reservoir containing one or two doses of a fluid, the reservoir including a stopper that closes the reservoir in leaktight manner before actuation; a dispenser head that is provided with a dispenser orifice; and dispenser mechanism for dispensing at least a portion of the fluid through the dispenser orifice during actuation. The device further includes a needle having a tip that is adapted to pierce the stopper during actuation, the reservoir being filled with the fluid and being closed with the stopper under a vacuum, so that the residual volume of air present in the reservoir between the fluid and the stopper is substantially zero.

摘要： A pump for a fluid product having a pump body held in place by a valve holder fastened in the pump body; a piston sliding around a rod, provided with an inner axial channel axially closed on the lower side of the rod and communicating with the outside of the rod via a radial orifice, the piston having an outer sealing lip and an inner sealing lip; a gland having upwards an oblique or frustoconical surface of inclination appropriate to that of the inner sealing lip of the piston; an actuating spring between the rod and piston; and a return spring between the valve holder and the rod, urging the piston towards its rest position. The valve holder has an axial sleeve having an axial rib forming a mechanical stop in the actuating position between the lower axial end of the rod and the rib.

摘要： 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.
