Abstract
A device for dispensing single doses of powdered medicament has a housing for holding a container which has a number of sealed apertures containing individual encapsulating doses of medicament. The container can move relative to the housing to allow each aperture in succession to be brought into registry with an airway which communicates with a mouthpiece. The device includes a piercing member, such as a pin, which can be inserted into a selected aperture to break its respective seals. The configuration and movement of the pin are such that this action expels substantially no powder from the aperture.
