An inhaler is disclosed. It comprises a housing to receive a strip having a plurality of blisters, each blister having a breachable lid and containing a dose of medicament for inhalation by a user, an indexing wheel mounted in the housing rotatable to drive a strip to sequentially move blisters into alignment with a blister piercing member, a control element pivotally mounted to the housing and a drive mechanism configured to couple the control element to the indexing wheel during part of the rotation of the control element by a user so that the indexing wheel rotates together with the control element.

Inhaler

An inhaler is disclosed. It comprises a housing to receive a strip of blisters each having a puncturable lid 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 operable to sequentially move each blister into alignment with a blister piercing member. 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.

An inhaler () is disclosed. It comprises a housing () to receive a strip () of blisters () each having a puncturable lid () 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 () operable to sequentially move each blister into alignment with a blister piercing member (). 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 but of the blister and via the mouthpiece into the user's airway.

An inhaler for dispensing medicament in the form of a dry powder is powder is provided with an airway () through which a dose travels from an ejection zone to an outlet of the airway. The airway () has an inlet means which is so arranged as to create a jacket of air, flowing through a part of the airway extending from the ejection zone to the outlet. The jacket of air surrounds said dose and thereby prevents it form impinging on the airway walls. This reduces accumulation of material on the airway walls, and thus improves the consistency of performance of the inhaler. Preferably, the inlet means includes a throat for producing a stream of fast flowing air which creates a zone of low pressure in front of the ejection zone, thereby to facilitate ejection of a dose.
