摘要：
The dry powder inhaler (10) comprises an intake section (20)； a mixing section (30), and a mouthpiece (40). The mouthpiece is connected by a swivel joint to the mixing section, and may swivel back into the intake section and be enclosed by a cover (290). The intake chamber comprises a piston with a tapered piston rod and spring, and one or more bleed-through orifices to modulate the flow of air through the device. It optionally comprises a feedback module to generate a tone indicating when the proper rate of airflow has been achieved. The mixing section holds a capsule (300) with holes containing a dry powder medicament, and further opens and closes the capsule when the intake section is at a certain angle to the mouthpiece. The mixing section is a Venturi chamber to impart a cyclonic flow to air passing through the mixing chamber.
