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 first passageway, a second passageway, a second cavity, at least one exhaust port, and an entrainment cavity, wherein said first cavity is operatively associated with said second cavity through said first passageway, said second passageway is operatively associated with said first cavity, 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;

a plurality of first apertures 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 at least one of said first apertures 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 first apertures occluded as it rotates.

6. The apparatus of claim 1 wherein at least one of said second apertures may be partially occluded.

7. The apparatus of claim 6 further comprising a rotatable occlusion apparatus.

8. The apparatus of claim 7 wherein said rotatable occlusion apparatus varies the area of said second apertures occluded as it rotates.

9. The apparatus of claim 1 wherein said exhaust port is operatively associated with said second passageway.

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

11. The apparatus of claim 1 wherein said gas input is operatively associated with said injection nozzle through said means of pulsating a gas flow.

12. The apparatus of claim 11 wherein one said gas input is operatively associated with said nebulizer and said injection nozzle.

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

a breathing head assembly of unitary construction defining a first cavity, a first passageway, a second passageway, a second cavity, at least one exhaust port, and an entrainment cavity, wherein said first cavity is operatively associated with said second cavity through said first passageway, said second passageway is operatively associated with said first cavity, 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;

a plurality of first apertures 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.

14. The apparatus of claim 13 wherein at least one of said second apertures is adjacent to said injection nozzle.

15. The apparatus of claim 13 wherein at least one of said first apertures may be partially occluded.

16. The apparatus of claim 15 further comprising a rotatable occlusion apparatus.

17. The apparatus of claim 16 wherein said rotatable occlusion apparatus varies the area of said first apertures occluded as it rotates.

18. The apparatus of claim 13 wherein at least one of said second apertures may be partially occluded.

19. The apparatus of claim 18 further comprising a rotatable occlusion apparatus.

20. The apparatus of claim 19 wherein said rotatable occlusion apparatus varies the area of said second apertures occluded as it rotates.

21. The apparatus of claim 13 wherein said exhaust port is operatively associated with said second passageway.

22. The apparatus of claim 13 further comprising a means of pulsating a gas flow operatively associated with said injection nozzle.

23. The apparatus of claim 13 wherein said gas input is operatively associated with said injection nozzle through said means of pulsating a gas flow.

24. The apparatus of claim 23 wherein one said gas input is operatively associated with said nebulizer and said injection nozzle.
