Abstract: A powder inhaler comprising: a body that is provided with a dispenser orifice; a plurality of reservoirs each containing a dose of powder; a perforator to perforate a predosed reservoir on each actuation; and a dispersion channel including an inlet that is connected to the perforator and that receives the dose of powder from the reservoir, and an outlet connected to the dispenser orifice, the perforator controlled by inhalation, the dispersion channel including two bent channel portions, a first bent channel portion that is connected to said inlet via a first substantially-rectilinear channel portion, and a second bent channel portion connected to the outlet via a second substantially-rectilinear channel portion, the two bent channel portions being interconnected via a third substantially-rectilinear channel portion, the cross-section of the third substantially-rectilinear channel portion being smaller than the cross-section of the first substantially-rectilinear channel portion.

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 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.

Abstract: A powder inhaler device comprising: a body provided with a dispenser orifice (15); at least one reservoir containing a dose of powder to be dispensed; reservoir opening means for opening a reservoir on each actuation; a dispersion chamber (70) including an outlet that is connected to said dispenser orifice (15), and an inlet (710) that is connected to said reservoir opening means and that receives the dose of powder from said open reservoir, said dispersion chamber (70) containing at least one movable element (75), said at least one movable element (75) including at least one peripheral hollow sleeve (755) on which at least one projecting element is fastened.

Abstract: A powder inhaler comprising: a body (10) that is provided with a dispenser orifice (15); a plurality of predosed reservoirs each containing a dose of powder for dispensing; and reservoir-opening means (80) for opening a reservoir on each actuation, said opening means being perforator means comprising a needle that is adapted to perforate a predosed reservoir on each actuation; the inhaler further comprising a dispersion channel (70) including an inlet (710) that is connected to said perforator means (80) and that receives the dose of powder from said open reservoir, and an outlet (720) that is connected to said dispenser orifice (15), said perforator means being controlled by the user inhaling, such that a predosed reservoir is simultaneously perforated and emptied, the powder driven by the inhalation flow passing through said dispersion channel before being expelled through the dispenser orifice, said dispersion channel (70) including two bent channel portions (71, 72), a first bent channel portion (71) that
