摘要:
A dry powder inhaler (10) having a chamber (26) divided into first and second blister compartments (28, 30) for storing unused and used portions (34, 36) of a blister strip (12) is provided. A moveable dividing wall (32) separates the first and second blister compartments. One or more arcuate supporting surfaces (38, 40, 42) are disposed in either the first and/or the second blister compartments and these surfaces support the used or unused blister strip during successive actuations of the inhaler. Use of the arcuate supporting surfaces facilities compact coils of unused and used portions of blister strip, thereby reducing the size of the chamber required for the inhaler.

A blister strip advance mechanism comprising: an indexing gear train; drive means configured to drive said indexing gear train; and a hub (230) comprising a recess shaped to engage a first blister of a blister strip, said hub being rotatable by the indexing gear train to engage the first blister in said recess and move the engaged blister strip such that a second blister is moved to a dosing position at which the second blister (130) can be emptied; wherein the indexing gear train is configured to temporarily disengage said drive means from the hub when the second blister is in said dosing position. Also: a dosing mechanism comprising said blister strip advance mechanism; an inhaler comprising said dosing mechanism; a method for advancing a blister strip and a method for dosing a medicament comprising said method for advancing a blister strip.

Provided herein is a method of pulmonary delivering to a subject at least one pharmacologically active agent being in a plant material, which is effected by pulmonary delivering the agent to the subject using a metered dose inhaler device that is configured to vaporize at least one pre-determined vaporized amount of the agent upon controllably heating the plant material, wherein the pre-determined vaporized amount is selected so as to achieve at least one pre-determined pharmacokinetic effect and/or at least one pre-determined pharmacodynamic effect induced by the agent in the subject.
摘要:
The invention relates to a multi-dose inhaler for substances in powder form, for example comprising at least one dosring (2) with a plurality of preferably circular arranged powder chambers (1) intended for the respective dose of powdered substance, and a feed mechanism (5) that is arranged to feed the dose-ring (2) or dose-rings (2) in the intended direction of movement, with at least one seal (11,22) provided to seal the powder chambers (1) from each other and from the environment for retaining the doses of powder in each powder chamber (1). The invention is achieved by letting the advancing mechanism (5) be arranged to feed the dose-ring (2) or dose-rings (2) so that at least two powder chambers (1) at a time are moved to a position of delivery of the doses of powder, to an air channel (7) comprising at least a section (7a, b) that is arranged in the position of the powder chamber (1) that have been advanced, that the air channel (7) or its section (7a, b) is arranged to allow at least two powder chambers (1) to be opened for inhalation, substantially at the same time, in the air channel (7) so that the powder chambers (1) and their powder doses are exposed to the air channel (7) through which the powder doses are allowed to pass out through the air channel (7) and mixed with each other by means of the airflow.

摘要:
An inhaler comprising a housing to receive a strip having a plurality of blisters, each blister having a puncturable lid and containing a dose of medicament for inhalation by a user is disclosed. The inhaler has a mouthpiece mounted to the housing and through which a dose of medicament is inhaled by a user, a cap that covers the mouthpiece in a closed position and an actuating element. The cap and the actuating element are mounted coaxially for rotation about a first axis to sequentially move each blister into alignment with a blister piercing member upon rotation of the cap by a user about said first axis into an open position in which the mouthpiece is revealed. The blister piercing member is mounted for rotation about a second axis and cooperates with the actuating element so that the blister piercing member pivots about said second axis in response to rotation of the cap about the first axis to puncture the lid of an aligned blister. An airflow through the blister is generated to entrain the dose contained therein and carry it, via the mouthpiece, into the user's airway when a user inhales through the mouthpiece.
