INHALATION DEVICES

摘要

An inhalation device comprises a body with a dispersion chamber. A rotor is arranged in the chamber and is caused to rotate by passage of air through the chamber. One or more air inlet apertures open into the chamber around the rotor. A mouthpiece communicates with the chamber and air from the chamber can be inhaled through this mouthpiece. A capsule-retaining pocket is arranged to receive a pierced capsule and opens into the chamber. Inhalation of air through the mouthpiece will draw medicament from the capsule through the chamber and out through the mouthpiece and will at the same time rotate the rotor.
