Abstract:
An inhaler comprising a chamber defined by(a) first and second generally parallel spaced opposed walls defining a median plane of said chamber mid-way therebetween, said inhaler including(b) a capsule disposed between said parallel spaced walls, said capsule having a length greater than the space between said first and second walls and having a longitudinal axis that is generally parallel to said first and second walls in any angular orientation, said chamber having(c) at least one peripheral wall;(d) an exhaust nozzle in communication with said chamber through which inhalation air can be exhausted from said chamber by inhalation;(e) at least one air inlet arranged in relation to the exhaust nozzle for generating in the chamber during inhalation an airflow of inhalation air rotating about an inhalation air axis generally perpendicular to said first and second walls; and(f) holding means having an axis of symmetry in the inhaler in association with(g) opening means operable from outside the chamber when closed for opening a capsule held in the holding means, wherein, during use of the inhaler, the holding means is effective to hold said capsule having a length greater than the space between said first and second walls said holding means being configured to hold said capsule having a diameter less than said space between the first and second walls; wherein said holding means are effective to hold said capsule with its longitudinal axis perpendicular to said inhalation air axis airflow within said chamber is rotating during inhalation.
