Abstract
A dry powder inhaler comprises a housing that has a portion that receives a dose of powdered medicament, a patient port that is placed in fluid communication with a patient; an inhalation passageway in communication with the patient port, a deagglomerator that deagglomerates or assists in aerosolization of the dose of powdered medicament; an electric powered device that drives the deagglomerator; a patient-independent energy output source that drives the electric powered device, a detector that detects inspiratory flow through the inhalation passageway; and a controller for actuating the deagglomerator in response to detection of the inspiratory flow by the detector.
