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.

Claims

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.

2. The apparatus of claim 1 wherein at least one of said second apertures is integrated with said injection nozzle.

3. The apparatus of claim 1 wherein said at least one first aperture may be partially occluded.

4. The apparatus of claim 3 further comprising a rotatable occlusion apparatus.

5. The apparatus of claim 4 wherein said rotatable occlusion apparatus varies the area of said at least one first aperture occluded as it rotates.

6. The apparatus of claim 1 wherein said pressure monitoring port is provided as part of said injection nozzle.

7. The apparatus of claim 1 further comprising a means of pulsating a gas flow operatively associated with said injection nozzle.

8. The apparatus of claim 7 wherein said at least one gas input operatively associated said injection nozzle is operatively associated with said injection nozzle through said means of pulsating a gas flow.

9. A continuous high-frequency oscillation breathing treatment apparatus comprising:

a breathing head assembly of unitary construction 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.

10. The apparatus of claim 9 wherein at least one of said second apertures is adjacent to said injection nozzle.

11. The apparatus of claim 9 wherein said at least one first aperture may be partially occluded.

12. The apparatus of claim 11 further comprising a rotatable occlusion apparatus.

13. The apparatus of claim 12 wherein said rotatable occlusion apparatus varies the area of said at least one first aperture occluded as it rotates.

14. The apparatus of claim 12 wherein said pressure monitoring port is provided as part of said injection nozzle.

15. The apparatus of claim 9 further comprising a means of pulsating a gas flow operatively associated with said injection nozzle.

16. The apparatus of claim 15 wherein said at least one gas input operatively associated with said injection nozzle is operatively associated with said injection nozzle through said means of pulsating a gas flow.
