Abstract: The invention provides a dosing system for an inhalation device, comprising a filling chamber (10); a reservoir chamber (31) which supplies liquid (3) to an aerosol generator (301); and a plunger (20) which includes an overflow chamber (25) and which is pivotable about a hinge (50). The filling chamber has an inner wall (12) which is higher on the side adjacent to the hinge than on the opposite side. When the filling chamber is filled with liquid and the plunger is pivoted into the filling chamber, part of the liquid is displaced over the lower side (17) of the inner wall into the reservoir chamber and some or all of the remaining liquid is displaced into the overflow chamber. The invention also provides an inhalation device comprising the dosing system and a method for dosing liquid to the inhalation device.

Abstract: An inhaler for delivering a preferably powdered formulation from a blister strip having a plurality of blister pouches. In order to achieve a compact simple construction for the inhaler and an easy action for the blister strip, the carrier extends over a circumferential angle of the inhaler of less than 360°. In particular, the carrier is guided between two deflectors with an at least substantially constant curvature, and preferably, exclusively along an outer wall of the inhaler. A conveying device of the inhaler has four drive wheels of the same diameter which are arranged on a common radius and are driven by common drive means in the same direction of rotation.

Abstract: A blister piercing element for puncturing the lid of a blister containing a dose of medicament for inhalation by a user. The piercing element has an outlet opening for the passage of medicament entrained in an airflow out of the blister and, a piercing head extending beyond and overhanging the opening that cuts a flap in a lid of a blister and pushes it away from the opening during insertion.

Abstract: An inhaler comprising a housing defining a chamber to receive a strip having a plurality of blisters each containing a dose of medicament for inhalation by a user is disclosed. It comprises an actuating lever and a blister strip drive member rotatably mounted in the chamber to sequentially move each blister into a blister opening position. The blister strip drive member and the actuating lever comprise a drive gear and a drive gear element, respectively, that cooperate to effect rotation of the blister strip drive member in response to rotation of the actuating lever. The drive gear and drive gear element are disposed on the outside of the housing remote from the chamber.

Abstract: 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.

Each blister has a puncturable lid and contains a dose of medicament for inhalation by a user. A mouthpiece is pivotally mounted to the housing through which a dose of medicament is inhaled by a user. The inhaler also has an actuating mechanism including a lever operable to sequentially move each blister into alignment with a blister piercing member depending from the mouthpiece. The actuating lever is also operable to cause the mouthpiece to pivot so that the blister piercing member punctures the lid of an aligned blister so that, when a user inhales through the mouthpiece, an airflow through the blister is generated to entrain the dose contained therein and carry it, via the mouthpiece, into the user's airway.

Abstract: An Inhaler for delivering an aerosolised dose of a powdered drug for inhalation by a user is disclosed. The inhaler comprises a drug entreinment device to a receive a package having a piercable lid containing a dose to be delivered, the device including a drug outlet tube terminating with a primary piercing element to pierce an opening in said lid when a package is located in the inhaler, a secondary piercing member to pierce a plurality of peripheral openings in said lid and, an airflow path to enable the supply of a charge of gas into the package via said peripheral openings to scour the interior of a pierced package such that all or substantially all of the dose is entrained in the gas and flows out of the package via the drug outlet tube. A medicament pack is also disclosed.
