The invention relates to a powder inhaler which works according to the Bernoulli principle with replaceable cylindrical disposable capsules acting as active substance reservoirs. The powder inhaler is essentially comprised of a preferably cylindrical capsule chamber (1) which is provided with means for laterally opening the capsule (2), an air inlet opening in the capsule chamber (1), and an air outlet opening and a mouthpiece which is arranged downstream from the air outlet opening. The capsule chamber (1) is designed in such a way that the used reservoir capsule (2) can essentially only carry out movements in a longitudinal direction when a sufficiently strong flow of air is guided through the capsule chamber (1) in a substantially parallel manner in relation to the longitudinal axis of the capsule (2). According to the invention, the inner wall of the capsule chamber (1) is uneven (3,4) in order to improve emptying of the capsule in comparison with a smooth inner surface.
Inhalateur de poudre fonctionnant selon le principe de Bernoulli, à l'aide de capsules jetables, de type cylindrique et remplaçables en tant que réservoir de principe actif. Ledit inhalateur de poudre est constitué pour l'essentiel d'une chambre (1) à capsule, de préférence cylindrique, pourvue de moyens destinés à l'ouverture latérale de la capsule (2), d'un orifice d'entrée d'air dans la chambre (1) à capsule, d'un orifice de sortie d'air et d'un embout buccal monté en aval de l'orifice de sortie d'air. La chambre (1) à capsule est ainsi conçue que la capsule-réservoir (2) introduite ne peut essentiellement effectuer que des mouvements dans le sens longitudinal lorsqu'un courant d'air suffisamment fort est guidé à travers la chambre (1), essentiellement parallèlement à l'axe longitudinal de la capsule (2). Selon la présente invention, la paroi interne de la chambre (1) à capsule comporte des irrégularités (3, 4), ce qui permet une meilleure vidange de la capsule que lorsque la surface interne est lisse
