A continuous high-frequency oscillation breathing device delivers therapy during both inhalation and exhalation in order to assist in clearing secretions from the lungs. A venturi patient interface circuit is combined with medicated aerosol to deliver continuous high-frequency oscillation therapy. Fixed open apertures in the patient interface circuit allow ingress and egress of flow, and are calibrated to allow exhalation and prevent stacking of successive breaths.

What is claimed is: 1. A continuous high-frequency oscillation breathing treatment apparatus comprising:a breathing head assembly defining a first cavity, a second cavity spaced from the first cavity, a pressure monitoring port, and an entrainment cavity, wherein said first cavity is operatively associated with said second cavity through a venturi tube, said first cavity is operatively associated with said pressure monitoring port through a feedback tube that extends generally parallel with the venturi tube, and said entrainment cavity is operatively associated with said second cavity;a nebulizer operatively associated with said entrainment cavity of said breathing head assembly;an injection nozzle operatively associated with said second cavity of said breathing head assembly;at least one first aperture operatively associated with said first cavity of said breathing head assembly;a plurality of second apertures operatively associated with said second cavity of said breathing head assembly;at least one gas input operatively associated with said nebulizer; andat least one gas input operatively associated with said injection nozzle.
