Dry powder inhaler |
摘要 |
A dry powder medicine inhaler has an impeller non-concentrically disposed in a mixing chamber. A motor spins the impeller at high speed. A plunger introduces a dose of powdered medicine into the chamber so that all powder particles are available for intermixing disaggregation and comminution. An aperture receives a first stream of air and passes it towards the mouthpiece for inhalation by the user. A wall has at least one aperture for diverting a portion of a main air stream into the aerosolizing chamber to mix with the particles to form a fine, low-density, low velocity, dry mist of powdered medicine for inhalation by the user. |
