Patent

CA 2738739

The invention relates to an inhaler comprising an outlet through which doses of medicament may be dispensed. The inhaler also comprises a dispensing mechanism having a primed state, in which it is ready for dispensing a dose, and a fired state, in which it has dispensed a dose. In one aspect, the inhaler also comprises a disabler which, after the final dose has been dispensed, is activated to disable the dispensing mechanism from generating a sound which has been audible when the dispensing mechanism has moved from its primed state to its fired state. In a second aspect, the disabler prevents the dispensing mechanism from being in its primed state when an outlet cover is in an open position, whereby a not ready indication is presented to the user.

L'invention concerne un inhalateur qui comprend une sortie par laquelle des doses de médicament peuvent être administrées. L'inhalateur comprend également un mécanisme de distribution qui présente un état amorcé dans lequel il est prêt à administrer une dose et un état épuisé dans lequel il a administré une dose. Selon un aspect, l'inhalateur comprend également un dispositif de désactivation qui, après que la dernière dose a été administrée, est activé pour désactiver l'émission par le mécanisme de distribution d'un son qui peut être entendu lorsque le mécanisme de distribution passe de son état amorcé à son état épuisé. Selon un deuxième aspect, le dispositif de désactivation empêche que le mécanisme de distribution soit dans son état amorcé lorsqu'un couvercle de sortie est en position ouverte, suite à quoi une indication "pas prêt" est présentée à l'utilisateur.
