Abstract

A non-invasive ventilation patient interface comprises a fresh gas entry port, a frame, and a zygomatic facial interface. The fresh gas entry port is configured for coupling with a fresh gas supply. The frame is configured for coupling with a head strap system, wherein the head strap system is configured for supplying a securing force to secure the patient interface in a position over a respiratory opening of a patient. The zygomatic facial interface is coupled with the frame and configured for spreading the securing force away from a nasal bridge of the patient and onto left and right zygomatic arch regions of the patient.

Claims

1. A non-invasive ventilation patient interface, said patient interface comprising:

a fresh gas entry port configured for coupling with a fresh gas supply;

a frame configured for coupling with a head strap system, wherein said head strap system is configured for supplying a securing force to secure said patient interface in a position over a respiratory opening of a patient; and

a zygomatic facial interface coupled with said frame and configured for spreading said securing force away from a nasal bridge of said patient and onto left and right zygomatic arch regions of said patient.

2. The patient interface of claim 1, further comprising:

said head strap system, wherein said head strap system is configured for coupling from a left lateral portion of said frame, around a posterior skull of said patient, and to a right lateral portion of frame patient interface such that in response to donning of said patient interface, said head strap system applies said securing force.

3. The patient interface of claim 1, further comprising an extended chin portion.

4. The patient interface of claim 3, wherein said extended chin portion comprises a chin bellows.

5. The patient interface of claim 1, further comprising a jaw bellows.

6. The patient interface of claim 1, further comprising a compliant nose bridge seal.

7. The patient interface of claim 1, further comprising a flexible tubing coupled with said fresh gas entry port.

8. The patient interface of claim 7, wherein said flexible tubing is coupled with an omni-directional swivel.

9. The patient interface of claim 1, wherein said zygomatic facial interface comprises a plurality of inflatable bladders.

10. The patient interface of claim 1, wherein said zygomatic facial interface comprises a moisture purging feature configured for contacting facial skin of said patient and for facilitating a controlled and intentional leak of fresh respiratory gas between said moisture purging feature and said facial skin.

11. The patient interface of claim 1, wherein said zygomatic facial interface comprises a wicking feature configured for contacting facial skin of said patient and for wicking fluid from said facial skin.

12. The patient interface of claim 1, wherein a portion of said zygomatic facial interface is imbued with at least one of an emollient, an antibacterial, and a vasodilator.

13. The patient interface of claim 1, wherein a portion of said zygomatic facial interface is configured with a tube insertion region.

14. A non-invasive ventilation facial interface, said facial interface comprising:

a first portion configured for sealably interfacing with facial skin covering a left zygomatic arch region of a patient; and

a second portion configured for sealably interfacing with facial skin covering a right zygomatic arch region of said patient, wherein in response to application of a securing force for securing said facial interface over a respiratory opening of said patient, said first portion and said second portion are configured for spreading said securing force away from a nasal bridge of said patient and onto to said left and right zygomatic arch regions of said patient.

15. The facial interface of claim 14, wherein said first portion and said second portion each comprises a plurality of inflatable bladders.

16. The facial interface of claim 14, wherein said first portion and said second portion each includes a moisture purging feature configured for contacting facial skin of said patient and for facilitating a controlled and intentional leak of fresh respiratory gas between said moisture purging feature and said facial skin.

17. The facial interface of claim 14, wherein said first portion and said second portion each includes a wicking feature configured for contacting facial skin of said patient and for wicking fluid from said facial skin.

18. The facial interface of claim 14, wherein said first portion and said second portion each is imbued with an emollient.

19. The facial interface of claim 14, wherein said first portion and said second portion each is imbued with an antibacterial.

20. The facial interface of claim 14, wherein said first portion and said second portion each is imbued with a vasodilator.
