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 fluid dispenser device comprising: a dose counter for indicating the number of doses that have been dispensed or that remain to be dispensed, said counter comprising: at least one rotary counter element provided with indicator means, such as digits or numbers, and provided with a first set of teeth and with a second set of teeth; a movable actuator element adapted to co-operate with said first set of teeth of said counter element so as to turn it; and anti-return means adapted to co-operate with said second set of teeth so as to prevent said counter element from turning in the direction opposite to the direction that is imposed by said actuator element; said anti-return means comprising a tip that is substantially V-shaped, and that, after each actuation of the counter, co-operates with a respective tooth of said second set of teeth in a blocking position, said tip comprising a first branch that is adapted to co-operate in the blocking position with a blocking shoulder of said tooth, and a second branch tha

Abstract: A fluid dispenser device comprising: a body (10) provided with a dispenser orifice (15); at least one reservoir containing a dose of fluid, such as pharmaceutical powder; movable support means (50) that receive at least one reservoir, and that are displaceable between a non-dispensing position and a dispensing position; reservoir-opening means (80) for opening a reservoir when said opening means are actuated; stressing means for urging said movable support means towards said dispensing position, said stressing means including an elastically-deformable stressing element (51); blocking means (100) for retaining said movable support means in the non-dispensing position corresponding to a cocked position of said blocking means; and inhalation trigger means for releasing said blocking means and for enabling said movable support means, together with a reservoir, to be displaced towards said dispensing position at the time a user inhales; the device including means (700) for modifying the inhalation flow of the user

Abstract: A fluid dispenser device comprising: a body (10) provided with a dispenser orifice (15); dispenser means (50, 80) for dispensing a dose of fluid on each actuation; and a dose counter for indicating the number of doses that have been dispensed or that remain to be dispensed, said counter comprising: a first rotary counter element (127) provided with a first surface including first indicator means (125), such as digits, and provided with at least one first set of teeth (128, 129); a second rotary counter element (227) provided with a second surface including second indicator means (225), such as digits, and provided with at least one second set of teeth (228, 229); and a movable actuator element (160) that is displaceable between a first position and a second position, said actuator element including a projection (168) that is adapted to co-operate with said first set of teeth (128) of said first counter element (127), so as to cause said first counter element (127) to turn while said actuator element (160) is
