The invention relates to a method for entraining in an airflow a medicament powder contained in a cavity having a cavity opening. Large airflow vortices are provided, for instance, by means of an obstacle in a flow passage. The airflow with large vortices is arranged to by-pass the cavity opening, thereby generating an eddy in the cavity which contributes to entraining the powder in said airflow. The invention also relates to a medical dispenser, for instance an inhaler, in which said method may be performed.

Cette invention concerne un procédé pour entraîner dans un flux d'air un médicament en poudre contenu dans une cavité pourvue d'une ouverture de cavité. D'importants tourbillons du flux d'air sont créés, par exemple, au moyen d'un obstacle dans un passage d'écoulement. Le flux d'air présentant ces tourbillons est conçu pour contourner l'ouverture de cavité, ce qui génère ainsi un tourbillon dans la cavité qui contribue à entraîner la poudre dans ledit flux d'air. L'invention concerne également un distributeur de médicament, par exemple un inhalateur, mettant en uvre ledit procédé.
