Abstract
An inhaler for multiple dosed administration of a pharmacological dry powder consists externally of a housing (,) and of a protective cap (,) which can be removed from a special mouthpiece (,) fitted on the housing. Arranged on the inside there are a slide rail (,), a dosing slide (,), a shutter (,), a carriage (,), a funnel arrangement (,), a counter device (,), a valve shield (,) and a valve guide (,). Removal of the protective cap (,) initiates the dosing, with a dose received in the dosing cavity (,) being transported to the mouth-piece (,) by means of the dosing slide (,). Only upon application of a defined minimum intensity of inhalation is the shutter (,) moved by the suctioned valve shield (,), as a result of which the dose is released for inhalation. Completed with an electronic module and a controllable nozzle, all inhalation-relevant data can be recorded and the flow conditions regulated.
