摘要：
A dry powder aerosol delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The dry powder aerosol delivery device includes a housing, a cartridge, and a dry powder dispersion mechanism, and at least one differential pressure sensor. The dry powder delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The dry powder aerosol delivery device is then actuated to generate a plume of particles having an average ejected particle diameter within the respirable size range, e.g., less than about 5-6 µm, so as to target the pulmonary system of the user.
