Claims (13)
1. A nasal mask comprising:
a central body, the central body comprising an inlet aperture for receiving a delivered amount of gas;
a gas inlet rotatably disposed around the inlet aperture of the central body, the gas inlet comprising a central axis and a tube portion, wherein the tube portion receives the delivered amount of gas and has a tube axis, and wherein a tube angle is formed between the tube axis and the central axis of the gas inlet; and the tube angle is between about 0 degrees and about 130 degrees; and a face cushion attached to the central body.
a central body, the central body comprising an inlet aperture for receiving a delivered amount of gas;
a gas inlet rotatably disposed around the inlet aperture of the central body, the gas inlet comprising a central axis and a tube portion, wherein the tube portion receives the delivered amount of gas and has a tube axis, and wherein a tube angle is formed between the tube axis and the central axis of the gas inlet; and the tube angle is between about 0 degrees and about 130 degrees; and a face cushion attached to the central body.
2. The nasal mask of claim 1 wherein the tube angle is between about 0 degrees and about 90 degrees.
3. The nasal mask of claim 1 wherein the tube angle is between about 60 degrees and about 90 degrees.
4. The nasal mask of claim 1 wherein the tube angle is between about 75 degrees and about 90 degrees.
5. The nasal mask of claim 1 further comprising a forehead support connected to the central body and a forehead cushion removably mounted to the forehead support.
6. The nasal mask of claim 3 wherein the forehead support is pivotably corrected to the central body.
7. The nasal mask of claim 1 further comprising a rotation fitting having a first end and a second end, wherein the first end is rotatably disposed around the tube portion, and the second end receives a tube which supplies gas.
8. A nasal mask comprising:
a central body, the central body comprising an inlet aperture for receiving a delivered amount of gas and a strap arm, the strap arm comprising a holder;
a strap attachment comprising a holder bar and a flexible tab with a space disposed in between the holder bar and the flexible tab;
wherein, when the mask is worn by a user, the holder projects into the space between the holder bar and the flexible tab; and a face cushion attached to the central body.
a central body, the central body comprising an inlet aperture for receiving a delivered amount of gas and a strap arm, the strap arm comprising a holder;
a strap attachment comprising a holder bar and a flexible tab with a space disposed in between the holder bar and the flexible tab;
wherein, when the mask is worn by a user, the holder projects into the space between the holder bar and the flexible tab; and a face cushion attached to the central body.
9. The nasal mask of claim 8 further comprising a forehead support connected to the central body and a forehead cushion removably mounted to the forehead support.
10. The nasal mask of claim 9 wherein the forehead support is pivotably connected to the central body.
11. The nasal mask of claim 1 further comprising a gas inlet rotatably disposed around the inlet aperture of the central body and a rotation fitting having a first end and a second end, wherein the first end is rotatably disposed around the tube portion, and the second end receives a tube which supplies gas.
12. A method of using a nasal mask and a strap, wherein the nasal mask comprises a strap arm having a holder and the strap comprises a first end attached to the mask and a second end attached to a strap attachment, the method comprising:
