Device in a powder inhaler known in the art, which is designed for inhalation of a flow of air, which contains a pharmacologically active substance in micronised form. The powder inhaler comprises both a mouthpiece 2 with a mouthpiece opening 2a, and a container 3 with dispensing or dosing unit 6 for dispensing the active substance. The inhalation air flow is sucked in at least partially through an inhalation duct 7 located in the container part 3, the duct extending from an air inlet 8, connected to the surroundings, via the dispensing or dosing unit 6 to the mouthpiece 2. In the container and/or the mouthpiece 3 and 2 respectively there are fixed deflectors in the form, for example, of a helical duct section 13 designed to impart a powerful redirecting movement to the inhalation air flow for atomising the entrained powder particles to the respirable particle size range (not exceeding 5μm). <IMAGE> |
