Abstract
A dry powder inhaler including a housing defining a chamber for receiving a dose of powdered medicament, an inhalation port in fluid communication with the chamber, at least one airflow inlet providing fluid communication between the chamber and an exterior of the housing, and a flutter element in the chamber and associated with a dose of powdered medicament. The flutter element has a tensioned distal end proximate the at least one airflow inlet and a free proximal end opposite to the distal end and downstream of the inlet. The flutter element is configured to vibrate in response to airflow through the chamber and aerosolize the dose of powdered medicament.
