Abstract
An inhalation device is provided for inhalation of a powder medicament. The device comprises a body 55 defining a reservoir 56 for medicaments in powder form, an outlet 57 through which a user can inhale and a dosing member 53 with at least one metering recess 65 formed therein. The dosing member 53 is moveable between a position in which the at least one metering recess 65 communicates with the reservoir 56 to receive a dose of powder therefrom and a position in which the at least one metering recess 65 communicates with the outlet 57 to permit the user to inhale the dose. The at least one metering recess 65 is formed in a face of the dosing member 53, the face being mounted in contact against a similar mating face 60 of the body 55 at the lower end of the reservoir 56. At least one moveable weight may be incorporated within the device, adapted to strike an anvil surface when the device is shaken.
