Abstract:
1. A respiratory therapy device comprising: a housing defining a primary passageway having a patient interface side; a flow diverter structure maintained by the housing in fluid communication with the primary passageway opposite the patient interface side, wherein the flow diverter structure is characterized by the absence of a venturi tube; a high frequency pressure port maintained by the housing and configured for fluid connection to a source of oscillatory gas flow, the high frequency pressure port being fluidly associated with the flow diverter structure, and the high frequency pressure port comprising a nozzle configured to generate a jet gas flow from the source of oscillatory gas; and an entrainment port maintained by the housing and openable to ambient air, the entrainment port being fluidly associated with the flow diverter structure; a nebulizer port formed by the housing in fluid communication with the primary passageway at a location fluidly between the patient interface side and the flow diverter structure; and a nebulizer fluidly connected to the nebulizer port.
