Abstract

Claims (22)

1. A ventilation mask for sealing on a face of a patient comprising:

a nasal passage opener configured for facilitating in opening a nasal passage of said patient, said nasal passage opener comprising a zygomatic facial interface portion configured to extend, when in use, over a zygomatic arch of said patient; and

side straps that extend from the nasal passage opener and are configured to extend around said patient's head to secure the mask on said patient's head;

wherein said nasal passage opener is configured to be disposed over said nasal passage of said patient when said ventilation mask is sealed on said face of said patient;

wherein said side straps and said zygomatic facial interface portion are configured (i) to stretch cheek skin of said patient laterally away from the nasal passage, (ii) to increase a cross-sectional area of a nasal passage of said patient when the side straps provide lateral pressure to the zygomatic facial interface portion, and (iii) to transfer the securing force from a nose bridge of the patient to the zygomatic arch of said patient.

2. The ventilation mask of claim 1 , wherein said nasal passage opener comprises:

a compliant nose bridge seal.

3. The ventilation mask of claim 1 , wherein said nasal passage opener comprises:

a bilateral cheek skin stretching feature of said mask.

4. The ventilation mask of claim 1 , wherein said nasal passage opener comprises:

an adjustable bladder.

5. The ventilation mask of claim 1 , wherein said nasal passage opener comprises:

a plurality of adjustable bladders.

6. The ventilation mask of claim 1 , wherein said nasal passage opener is integrated with said ventilation mask.

8. A method for assisting in opening a nasal passage, said method comprising:

sealing a ventilation mask over a face of a patient, wherein said ventilation mask is configured to encompass a nasal passage of said patient and includes zygomatic facial interface portions that extend laterally away from the nasal passage, when worn by the patient, to a position above the patient's zygomatic arches; and

drawing laterally away from the nasal passage, with side straps, the zygomatic facial interface portions, such that the zygomatic facial interface portions (i) laterally stretch the patient's cheek skin away from the nasal passage, (ii) increase a cross-sectional area of said nasal passage as the patient's cheek skin is stretched away from the nasal passage, and (iii) transfer a drawing force of the side straps from a nose bridge of the patient to the zygomatic arch of said patient.

9. The method of claim 8 , wherein said increasing a cross-sectional area of said nasal passage further comprises:

adjusting a bladder.

10. The method of claim 8 , wherein said increasing a cross-sectional area of said nasal passage further comprises:
