Abstract: A dry-powder inhaler including a body containing a dispersion chamber; a dispenser orifice through which the user inhales; a loading opening that receives a capsule containing a dose of dry powder for inhaling; and at least one movable portion that moves relative to the body between a first end position and a second end position; the dispersion chamber containing at least a portion of an empty capsule at the moment of inhalation, the at least one capsule portion swirling in the dispersion chamber during inhalation so as to disperse and/or break up the powder.

Abstract: A dry-powder inhaler (100; 200) having: a body (110; 210) forming a dispersion chamber (111; 211); a dispenser orifice (131; 231) through which the user inhales; a loading opening (121; 220) that receives a capsule (10) containing a dose of dry powder for inhaling; and capsule opening mechanism (140; 265) for opening a capsule inserted into said loading opening and emptying the dose of powder into said dispersion chamber. The body (110; 210), at least at one wall of said dispersion chamber, is made of a tinted transparent material that is adapted to filter UV rays, at least in part, and to make it possible to see the inside of the dispersion chamber while masking, at least in part, residues of powder that are stuck to the at least one wall of tinted transparent material.

Abstract: A fluid dispenser device comprising a body (10) provided with a dispenser orifice (15), said device further comprising: an elongate flexible strip (20) supporting a plurality of reservoirs (21) each containing a dose of fluid; reservoir-opening means (80) for opening a respective reservoir on each actuation; first displacement means (30) for causing said flexible strip (20) to advance before and/or during and/or after each actuation, so as to bring a full reservoir into register with said reservoir-opening means; and second displacement means (50) for displacing a full reservoir (21) against said opening means (80) each time the device is actuated, said device including positioning means (300) that are adapted to position the full reservoir accurately relative to the reservoir-opening means (80) when it is displaced thereagainst, so as to guarantee that opening is predetermined and reproducible on each actuation.

Abstract: A fluid dispenser device including a body provided with a dispenser orifice; at least one reservoir containing a dose of fluid, such as pharmaceutical powder; a movable support mechanism that receives at least one reservoir, and that is displaceable between a non-dispensing position and a dispensing position. A reservoir-opening mechanism opens a reservoir when actuated and a stressing mechanism that includes an elastically-deformable stressing element, urges the movable support mechanism towards a dispensing position. An inhalation trigger releases a blocking element and which enables the movable support mechanism, together with a reservoir, to be displaced towards the dispensing position at the time a user inhales.

Abstract: A method of surface treating a fluid dispenser device, said method comprising a step of modifying at least one surface to be treated of at least a portion of said device in contact with said fluid by ionic implantation using multi-charged and multi-energy ion beams, said modified surface to be treated having non-stick properties for said fluid, said multi-charged ions being selected from helium (He), nitrogen (N), oxygen (O), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe), ionic implantation being carried out to a depth of 0 ?m to 3 ?m.

Abstract: A method of using a dry-powder inhaler, including providing a dry-powder inhaler (100; 200) having a body (110; 210) containing a dispersion chamber (111; 211), a dispenser orifice (131; 231) through which the user inhales, a loading opening (121; 220) that receives a capsule (10) containing a dose of dry powder for inhaling, and at a movable portion (130; 260) that moves relative to the body between a first end position and a second end position; inserting a full capsule (10) into the loading opening (121; 220); moving the movable portion from one of its end positions to its other end position to open the capsule and empty the powder into the dispersion chamber; inhaling the powder through the dispenser orifice; and returning the movable portion towards its initial position so as to open the dispersion chamber and eject the empty capsule.
