EP2082772A1 — Inhaler

USPTO Abstract

An inhaler (10) comprising a housing (11) to receive a strip (14) having a plurality of blisters (14a), each blister (14a) having a puncturable lid (14c) and containing a dose of medicament for inhalation by a user, a mouthpiece (13) through which a dose of medicament is inhaled by a user, a cap (12) to cover the mouthpiece (13) and a blister piercing element (16) to pierce the lid (14c) of a blister (14a) is disclosed. The cap (12) is rotatable to drive the strip (14) to sequentially move each blister (14a) into alignment with the blister piercing element (16) and an actuator is operable in response to rotation of the cap (12) to cause the blister piercing element (16) to puncture the lid (14c) of an aligned blister (14a) such that, when a user inhales through the mouthpiece (13), an airflow through the blister (14a) is generated to entrain the dose contained therein and carry it out of the blister (14a) and via die mouthpiece (13) into the user's airway.
