摘要：
A dry powder inhaler (10) comprising, in combination, a mouthpiece (40) adapted to deliver dry powder particles comprising a medicament to a users bronchial tract and lungs and a housing (15), the housing having a mixing cavity (30) adapted to selectively mount a medicament-containing cartridge (301), an air intake section (20), and an airflow passage (50) or conduit for assisting in the delivery of air from the air intake section into and through a cartridge in the mixing cavity and into and through the mouthpiece wherein the mouthpiece (40) comprises a hollow tube having an axis defining a mouthpiece airflow passage, and, the mixing chamber comprises a hollow cylinder having an axis, and wherein the mouthpiece is oriented to the long dimension of the housing at an angle of between 90 degrees and 180 degrees and wherein the mouthpiece (40) diverges the air and particle stream to slow down the dry powder particles and cause the particles to converge at the rear of the users mouth and the mouthpiece and the housing comprise a joint that allows for the mouthpiece to pivot to an open (cartridge loading) or closed (in-use) configuration.
