Summary for Patent: 8,474,447

Title:Inhaler device
Abstract: The invention relates to a hand-held device (1), as depicted in exemplary FIG. 4, for metered dispensing of sprayable substances, particularly medicaments for inhalation, with a cartridge (3) that can be moved into the dispensing position, by pressure being applied to a housing, and with a step-by-step indexing mechanism (11) which is entrained by the cartridge (3) in the opening travel thereof and which is used to record and display the dispensing actuations that have been performed. In order to suitably design a hand-held device of the type in question with a simplified structure, in such a way that the indexing steps can be performed smoothly and safely without connection to the cartridge, it is proposed that slits (19) extend obliquely only over part of the travel of the step-by-step indexing mechanism housing (34) and that the guide pins (33) guided therein move, over the remainder of the travel of the step-by-step indexing mechanism (11), parallel to the longitudinal axis (x-x) of the step-by-step indexing mechanism.
