The present invention comprises a dry powder inhaler (DPI) that uses a patientsinhalation flow to concentrate energy in an aeroelastic element for deaggregationand dispersion of a powder dose. The result is a DPI that delivers a dose independentof inspiratory abilities of the patient, solving a major problem of conventionalDPIs. Increased tension on the aeroelastic element causes higher frequencyvibrations and improved powder dispersion. The tension of the aeroelastic elementcan be modified prior to dispensing the DPI to the patient, allowing for individualizationfor single patients or groups of patients. In addition, the DPI has features thatincrease the turbulence of the airflow as it passes through the device, furtherincreasing the dispersion and deaggregation of the powder. The DPI can hold asingle dose or multiple doses. The powder doses can be dispensed directly ontothe aeroelastic element, or may be in adjacent blister packaging.
