Patent

CA 2542473

An inhaler (1) is disclosed. It comprises a housing (2) to receive a strip (6) of blisters (6a) each having a puncturable lid (6c) and containing a dose of medicament for inhalation by a user, a mouthpiece through which a dose of medicament is inhaled by a user and, an actuator (3) operable to sequentially move each blister into alignment with a blister piercing member (7, 9). The actuator is also operable to cause the blister piercing element to puncture the lid of a blister such that, when a user inhales through the mouthpiece, an airflow through the blister is generated to entrain the dose contained therein and carry it out of the blister and via the mouthpiece into the user's airway.

La présente invention se rapporte à un inhalateur (1). L'inhalateur selon l'invention comprend : un logement (2) destiné à recevoir une plaquette (6) constituée d'alvéoles (6a), chacun de ces derniers possédant un opercule perforable (6c) et contenant une dose de médicament destinée à être inhalée par un utilisateur ; un embout buccal à travers lequel une dose de médicament est inhalée par un utilisateur ; et un actionneur (3) pouvant déplacer successivement chaque alvéole de façon à l'aligner avec un élément de perforation d'alvéole (7, 9), lequel perce l'opercule d'un alvéole de façon que, lorsqu'un utilisateur procède à l'inhalation à travers l'embout buccal, un flux d'air traversant l'alvéole soit généré, ce qui entraîne la dose contenue à l'intérieur, la fait sortir de l'alvéole, traverser l'embout buccal et pénétrer dans les voies aériennes de l'utilisateur.
