The inhaler is intended for multiple dosed administration of a pharmacological dry powder and consists externally of a housing (100,150) and of a protective cap (950) which can be removed from a special mouthpiece (900) fitted on the hous- ing. Arranged on the inside there are a slide rail (200), a dosing slide (300), a shutter (400), a carriage (500), a funnel arrangement (600), a counter device (700), a valve shield (800) and a valve guide (850). Removal of the protec- tive cap (950) initiates the dosing, with a dose received in the dosing cavity (302) being transported to the mouth-piece (900) by means of the dosing slide (300). Only upon applica- tion of a defined minimum intensity of inhalation is the shutter (400) moved by the suctioned valve shield (800), as a result of which the dose is released for inhalation. Com- pleted with an electronic module and a controllable nozzle, all inhalation-relevant data can be recorded and the flow conditions regulated. |
