摘要：
A respiratory therapy device including a housing, a flow diverter structure,a high frequency pressure port (HF port), and an entrainment port. The housingdefines a primary passageway having a patient interface side. The flow diverterstructure is in fluid communication with the primary passageway and is characterizedby the absence of a venturi tube. The HF port is configured for fluid connectionto a source of oscillatory gas flow, and is fluidly associated with the flow diverterstructure. The entrainment port is openable to ambient air, and is fluidly associatedwith the flow diverter structure. With this construction, the device is configuredsuch that flow characteristics of gas flow from an external source are alteredupon interacting with the flow diverter structure to create a pressure drop fordrawing in ambient air through the entrainment port in delivering a percussivepressure therapy to the patient side.
