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; and
at least one gas input operatively associated with said injection nozzle.

Abstract
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.
