Abstract

A breathing apparatus with improved ergonomic aspects to more comfortably accommodate patients breathe while preventing their lungs from collapsing. The present breathing apparatus comprises an apparatus body having proximal and distal ends with at least one hollow passageway extending therebetween. A pair of nostril-engaging stems with generally D-shaped base configurations conform to the anatomy of patient'"'"'s nostrils and a connector assembly having a rotatable mid portion is used at the apparatus body'"'"'s distal end to allow moderate movement and thereby reduce torque applied to a patient'"'"'s face.

Claims

1. An apparatus to assist in breathing while anatomically conforming to patient'"'"'s nostrils, the apparatus comprising:

an elongated apparatus body having proximal and distal ends and defining at least one hollow passageway extending therebetween;

nostril-engaging stems sized and configured to outwardly protrude from the proximal end and fluidly communicating with the passageway(s), each of the nostril-engaging stems having a peripheral wall with top and base portions, each of the base portions forming a D-shaped configuration to anatomically conform to the patient'"'"'s nostrils; and

wherein atmospheric air and pressurized gas flow from the passageway(s) to the proximal end so as to be supplied to the patient'"'"'s nostrils when the nostril-engaging stems are engaged therein.

2. The apparatus of claim 1 wherein the apparatus body is fabricated from a plastic material.

3. The apparatus of claim 1 wherein the at least one passageway comprises two passageways extending in a parallel relationship to each other between the proximal and distal ends of the apparatus body.

4. The apparatus of claim 1 wherein the apparatus body comprises a positive pressure portal fluidly communicating with the passageway(s) to introduce the atmospheric air and pressurized gas thereinto.

5. The apparatus of claim 4 wherein the positive pressure portal is in fluid communication with the passageway(s) via an ejector inlet channel.

6. The apparatus of claim 5 wherein the ejector inlet channel has at least one inlet end disposed within the passageway(s) and facing toward the proximal end for guiding the atmospheric air and pressurized gas thereto.

7. The apparatus of claim 1 wherein the apparatus body comprises a pressure sensor portal fluidly communicating with the proximal end.

8. The apparatus of claim 1 wherein the nostril-engaging stems are fabricated from an elastic material.

9. The apparatus of claim 1 wherein each of the top portions have a substantially annular configuration.

10. The apparatus of claim 1 further comprising a nose-piece member having apparatus and nose ends, the apparatus end being engaged with the proximal end, the nose end forming the outwardly protruding nostril-engaging stems thereon.

11. The apparatus of claim 10 wherein the apparatus end is removably engaged with the proximal end of the apparatus body.

12. The apparatus of claim 10 wherein the apparatus end is engaged with the proximal end of the apparatus body via a frictional fit.

13. The apparatus of claim 10 wherein the nostril engaging stems are unitarily formed on the nose end of the nose-piece member.

14. The apparatus of claim 10 wherein the nose-piece member defines nose channels to fluidly communicate the passageway(s) with the nose-engaging stems.

15. An apparatus to assist in breathing while reducing torque applied to a patient'"'"'s face, the apparatus comprising:

an elongated apparatus body having proximal and distal ends and defining at least one hollow passageway extending therebetween; and

a connector assembly engaged to the distal end and fluidly communicating with the passageway(s), the connector assembly having a mid portion sized and configured to allow relative rotation between the apparatus body and the connector assembly to reduce torque applied to the patient'"'"'s face when the proximal end is fitted thereon.

16. The apparatus of claim 15 wherein the apparatus body is fabricated from a plastic material.

17. The apparatus of claim 15 wherein the at least one passageway comprises two passageways extending in a parallel relationship to each other between the proximal and distal ends of the apparatus body.

18. The apparatus of claim 15 wherein the apparatus body comprises a positive pressure portal fluidly communicating with the passageway(s) to introduce atmospheric air and pressurized gas thereinto.

19. The apparatus of claim 15 wherein the apparatus body comprises a pressure sensor portal fluidly communicating with the proximal end.

20. The apparatus of claim 15 wherein the connector assembly comprises a hose connector with a breathing end and a passageway connector with a passageway end, the breathing and passageway ends jointly forming the rotatable mid portion when connected together.

21. The apparatus of claim 20 wherein the breathing and passageway ends are sized and configured to swivel with respect to each other.

22. The apparatus of claim 21 wherein a ball-and-socket joint connection is formed between the breathing and passageway ends.

23. The apparatus of claim 20 wherein the passageway connector comprises a body end for engaging the distal end of the apparatus body.

24. The apparatus of claim 23 wherein the body end is axially insertable into the passageway(s) through the distal end of the apparatus body.

25. The apparatus of claim 24 wherein the body end is retained within the passageway(s) via a frictional fit and forming a coaxial relationship therewith.

26. The apparatus of claim 15 further comprising a nose-piece member having apparatus and nose ends, the apparatus end being engaged with the proximal end of the apparatus body, the nose end forming outwardly protruding nostril-engaging stems adapted to be fitted to the patient'"'"'s face.
