Abstract

L'invention concerne un appareil à main (1) permettant le dosage de substances pulvérisables, notamment de médicaments à inhaler. Cet appareil à main comprend une cartouche (3) pouvant être amenée en position de délivrance par déplacement axial dans un boîtier (2), et un mécanisme pas à pas (13) associé à cette cartouche et permettant d'enregistrer et d'afficher les actionnements de délivrance effectués. L'invention vise à créer un appareil à main de type susmentionné ayant une configuration dimensionnelle favorable pour une construction facile à nettoyer, simplifiée et stable. A cet effet, le mécanisme pas à pas (13) repose sur la plaque de base (14) qui est en contact sécant avec le boîtier (2) et librement portée par l'enveloppe de la cartouche (3). Cette plaque de base porte la roue à cliquet (30) et l'amène avec la cartouche (3) en prise d'avancement pas à pas vers un cliquet (36) solidaire du boîtier lors de leur actionnement de délivrance.
