Abstract

A full face mask made of cloth having a nasal portion, an oral portion and transition portions is disclosed. The nasal and oral portions are made of a cloth that is impermeable to air and have nasal and oral interfaces on them to facilitate a seal with a user'"'"'s face. The transition portions have easy removal clips for the lower headgear straps and sealing assistance members for better sealing.

Claims

1. A full-faced respiratory mask for supplying air from an air hose to both a user'"'"'s mouth and nasal passages at a therapeutic pressure comprising:

an oral portion, comprising a moisture-vapor breathable cloth material, having a first inflated oral configuration where the presence of the supplied air cooperates with the material to create an oral chamber maintaining a fixed shape and a second uninflated oral configuration where the fixed shape is not maintained due to the absence of supplied air, the oral portion having a proximal surface with an oral interface that forms an oral portion seal around the user'"'"'s mouth and having an aperture formed therein for delivering air to the user'"'"'s mouth, a distal surface having a substantially circular aperture of a first diameter formed therein, and an upper wall;

a nasal portion, comprising a moisture-vapor breathable cloth material, having a first inflated nasal configuration where the presence of the supplied air cooperates with the material to create a nasal chamber maintaining a fixed shape and a second uninflated nasal configuration where the fixed shape is not maintained due to the absence of the supplied air, the nasal portion being separate from the oral portion, being disposed above the oral portion, and having a proximal surface forming a nasal interface that creates a nasal portion seal encircling the user'"'"'s nasal passages for noninvasively delivering air to the user'"'"'s nasal passages and a lower wall;

the lower wall of the nasal portion connected to the upper wall of the oral portion via a shared aperture having a diameter no greater than the first diameter;

an air delivery arrangement comprising an elbow and an internal connector;

the elbow having a first end and a second end, the first end sealingly disposed on the air hose and the second end having a connector ring that extends through the substantially circular aperture in the oral portion into the oral chamber and sealingly mates with the internal connector, whereby the internal connector and connector ring cooperatively clamp the oral portion cloth material around the circumference of the substantially circular aperture and sealingly connect the air delivery arrangement to the cloth material of the oral portion;

whereby air at therapeutic pressure is supplied through the air delivery arrangement to the oral portion of the mask and inflates both the oral portion and the nasal portion causing them to assume and maintain the first inflated oral configuration and the first inflated nasal configuration and to resist deformation so that the air at a therapeutic pressure is applied to both the user'"'"'s mouth and nasal passages at the same time; and

an exhalation system.

2. The full-face respiratory mask of claim 1, wherein the cloth is comprised of a polyester cloth having a flexible coating comprising one of a polyester film or a polyurethane film.

3. The full-face respiratory mask of claim 1, wherein the material is substantially comprised of polyester, polyurethane, elastane and nylon.

4. The full-face respiratory mask of claim 1, wherein the oral portion'"'"'s first inflated configuration has a separately defined shape from the nasal portion'"'"'s first inflated configuration.

5. The full-face respiratory mask of claim 1, wherein the exhalation system comprises a plurality of apertures.

6. The full-face respiratory mask of claim 5, wherein the exhalation system further comprises seam apertures.

7. The full-face respiratory mask of claim 1, further comprising headgear and bilaterally disposed transition portions that connect the mask to the headgear.

8. The full-face respiratory mask of claim 7, wherein the transition portions further comprise sealing assistance members.

9. The full-face respiratory mask of claim 8, wherein the sealing assistance members are comprised of plastic and are sewn to the transition portion material.

10. The full-face respiratory mask of claim 9, wherein the transition portion material is polyethylene foam.

11. The full-face respiratory mask of claim 7, wherein the transition portion further comprises snap clips for easy removal and placement.

12. The full-face respiratory mask of claim 1, wherein the user can communicate verbally while wearing the mask.
