Abstract
A dry powder inhaler includes a chamber holding a bead-like actuator to which a powdered medicament is adhered. Air is drawn into the chamber through an inlet flow channel and exits through an outlet flow channel. The bead-like actuator oscillates in response to the air flow, dislodging powdered medicament to be entrained in the air flow and delivered to the patient.
