  • Dispenser and method for entraining powder in an airflow
    Patent number: 9211383
    Abstract: A device for inhalation of at least one air stream carrying a dose of medicament powder having a powder-containing cavity which opens into a flow passage. The flow passage is arranged to direct an inhalation air flow across the cavity opening. A circulating flow is thereby induced in the cavity by the phenomenon of shear driven cavity flow. Powder is entrained in the circulating flow and deaggregated before exiting the cavity and becoming entrained in the flow of air along the flow passage.
    Type: Grant
    Filed: June 30, 2010
    Date of Patent: December 15, 2015
    Assignee: ASTRAZENECA AB
