Abstract
A breath actuated dry powder medicament inhalator has a primary air passageway therethrough defining a venturi in the medial portion thereof. A secondary air passageway is provided which includes a compound deaggregating swirl chamber and is fluidly connected to the venturi of the primary air passageway. A dry powder compound storage chamber and cooperatively associated metering plate act to introduce a predetermined amount of compound into the swirl chamber upon actuation of the metering plate. The primary air passageway is configured within the inhalator apparatus so as to create an optimized air flow trajectory through the mouth of the user to minimize dry powder compound impingement upon the outside radius of the throat.
