    摘要： Described is a dry powder inhaler comprising an intake section; a mixing section, and a mouthpiece. The mouthpiece is connected by a swivel joint to the mixing section, and may swivel back onto the intake section and be enclosed by a cover. The intake chamber comprises a special piston with a tapered piston rod and spring, and one or more bleed-through orifices to modulate the flow of air through the device. The intake chamber further optionally comprises a feedback module to generate a tone indicating to the user when the proper rate of airflow has been achieved. The mixing section holds a capsule with holes containing a dry powder medicament, and the cover only can open when the mouthpiece is at a certain angle to the intake section. The mixing section 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 configured by protrusions or spirals to impart a cyclonic flow to air passing through the mixing chamber. The mouthpiece includes a tongue depressor, and a protrusion to contact the lips of the user to tell the user that the DPI is in the correct position. An optional storage section, with a cover, holds additional capsules. The cover for the mouthpiece, and the cover for the storage section may both be transparent, magnifying lenses. The capsules may be two-part capsules where each portion has apertures which correspond to apertures in the other half when each half is partially fitted to the other half, and fully fitted to the other half. All the apertures may be closed when the two halves are rotated around their longitudinal axes with respect to each other. Each capsule may have a unique key on each half that only fits with a particular inhaler.

    摘要： Described are capsules to contain a drug for use in an inhaler. The capsules may be two-part capsules where each half has apertures which may correspond to apertures in the other half. The first half fits snugly within the second half and the two halves may be rotated around their longitudinal axes with respect to each other to produce unlocked and locked positions. In the unlocked position, at least one aperture in the first half aligns with at least one aperture in the second half, which permits introduction of a medicament. In the locked position, at least two apertures in the first half align with at least two apertures in the second half, allowing air to pass through the capsule, releasing the medicament contained therein. Each capsule may have a unique key on each half that only fits with a particular inhaler or identifies the medicament contained therein.
