Patent ID: 7395821

Claim:
An inhaler device comprising first and second components movable relative to one another; means for receiving a medicament cartridge comprising a plurality of compartments containing medicament; medicament extraction facilitating means for locating adjacent a compartment of a received cartridge and thereby allowing an extraction of medicament therefrom; and operating means which, when activated by a user, advances a cartridge compartment of a received cartridge into a predetermined position relative to the medicament extraction facilitating means and extends the medicament extraction facilitating means into a position adjacent said advanced compartment for allowing medicament extraction upon inhalation by a user; wherein the operating means is mounted relative to said first and second components so as to be activated in response to said first and second components being moved relative to one another by a user, and wherein the operating means comprises biasing means for applying a force to a received cartridge which, on activation of the operating means, advances said compartment towards said predetermined position; the inhaler device being characterised in that the cartridge receiving means and the cartridge biasing means are secured to said first component, and in that the operating means further comprises two pins which are each further secured to said first component so as each to be movable between an extended position, in which the respective pin is engageable with a received cartridge so as to limit the cartridge advancement caused by said biasing force, and a retracted position, in which the respective pin is spaced from a received cartridge so as to not limit cartridge advancement.
