Abstract
A device utilized for the inhalation of medicament in a powder form. This device has a body portion with communicating primary and secondary air inlet channels and an outlet channel. The secondary inlet channel provides an enclosure for a capsule containing medicament and the outlet channel is formed in a mouthpiece protruding from the body portion. A capsule piercing structure is provided, which upon rotation puts holes in the capsule, so that upon vibration of the capsule, caused by an electro-mechanical vibration means, medicament is ejected from the capsule. After piercing and upon inhalation through the mouthpiece, and activation of the vibration means, powder is ejected into the airstream passing through the inlet channels, outlet channel, and into the user's mouth.
