  • Publication number: 20090205657
    Abstract: A dry powder inhaler including a housing having a mouthpiece and a delivery passageway connected to the mouthpiece, a magazine positioned within the housing and including a plurality of reservoirs for holding doses of dry powder, and wherein the magazine is movable within the housing so that the reservoirs are sequentially positioned within the delivery passageway of the housing upon movement of the magazine, a cover connected to the housing and movable to open and close the mouthpiece of the housing, and a rake connected to the cover, extending into the housing and engageable with the magazine so that, upon the cover being moved to open the mouthpiece, the rake moves the magazine and causes one of the reservoirs of the magazine to be positioned within the delivery passageway.

  • Patent number: 7261102
    Abstract: A medicament delivery system comprises a nebulizer device, an open-faced mist chamber-defining element having a tubular input/output port, a tubular inhalation port connecting to the output port of the mist chamber-defining element, and a sealed unit dose ampoule adapted to fit within the mist chamber-defining element. The nebulizer device includes an ultrasonic transducer responsive to applied electrical energy to generate ultrasonic energy, an ultrasonic transmission horn between an input energy surface at an input end and an energy delivery surface at an output end. The sealed unit dose ampoule can be placed directly into the nebulizer device and acts as both the dose cup and baffle, so that the chance of spillage of drug and the number of components to be cleaned are minimized.

The unit dose ampoule has a conical base to allow ultrasonic energy conducted from the ultrasonic system to be concentrated at the base of the ampoule. The inhalation port includes an inhalation valve and an exhalation valve.
