Abstract
L'invention concerne un inhalateur à poudre (1) comprenant un compartiment (3) destiné au stockage d'une dose d'agent pulvérulent, un passage (7) raccordant le compartiment (3) à la sortie (8), un ensemble valve (4, 5, 6, 10) placé au moins partiellement dans le passage (7) et permettant de garder le passage (7) fermé sauf si une dose de l'agent est destinée à être acheminée via le passage (7). L'ensemble valve (4, 5, 6, 10) s'ouvre lorsqu'une pression négative prédéterminée est générée dans la partie du passage (7), comprise entre l'ensemble valve et la sortie (8), par l'inhalation d'un patient. L'invention concerne également un procédé correspondant permettant d'administrer un agent pulvérulent dans les poumons d'un patient.
