Abstract

A liner for use with a respiratory mask having a face-engaging portion having nasal pillows is provided, where the liner includes a body constructed from an absorbent material, the body having a first set of apertures and a second set of apertures spaced from the first set of apertures. The first set of apertures receives the nasal pillows, and the second set of apertures is aligned with the nasal pillows when the liner is in a folded configuration.

Claims

1. A liner for use with a respiratory mask having a face-engaging portion including nasal pillows, the liner comprising:

a body constructed from an absorbent material, the body having a first pair of apertures and a second pair of apertures spaced from the first pair of apertures, the first pair of apertures receiving the nasal pillows, and the second pair of apertures aligned with the nasal pillows when the liner is in a folded configuration.

2. The liner of claim 1, wherein the first pair of apertures has a larger diameter than the second pair of apertures.

3. The liner of claim 1, wherein the first pair of apertures is adjacent a first end of the liner and the second pair of apertures is adjacent a second end of the liner when the liner is in a flat configuration.

4. The liner of claim 1, wherein the body comprises a single layer of material.

5. The liner of claim 1, wherein the material is stretchable.

6. The liner of claim 1, wherein the liner is treated with a copper or copper oxide material.

7. The liner of claim 1, wherein the liner is configured to be releasably held between the nasal pillows and a user'"'"'s face.

8. A liner for use with a respiratory mask having a mask connector and a face-engaging portion including nasal pillows, the liner comprising:

a body constructed from an absorbent material, the body having a first pair of apertures, a mask connector aperture spaced from the first pair of apertures, and a second pair of apertures spaced from and disposed between the first pair of apertures and the mask connector aperture, the first pair of apertures receiving the nasal pillows, the mask connector aperture receiving the mask connector, and the second pair of apertures aligned with the nasal pillows when the liner is in a folded configuration.

9. The liner of claim 8, wherein the first pair of apertures has a larger diameter than the second pair of apertures.

10. The liner of claim 8, wherein the first pair of apertures is adjacent a first end of the liner, the mask connector aperture is adjacent a second end of the liner, and the second pair of apertures is generally centrally disposed along a length of the liner when the liner is in a flat configuration.

11. The liner of claim 8, wherein the body comprises a single layer of material.

12. The liner of claim 8, wherein the material is stretchable.

13. The liner of claim 8, wherein the liner is treated with a copper or copper oxide material.

14. The liner of claim 8, wherein the liner is configured to be releasably held between the nasal pillows and a user'"'"'s face.

15. A liner for use with a respiratory mask having a face-engaging portion including nasal pillows and a mouthpiece, the liner comprising:

a body constructed from an absorbent material, the body having a first pair of apertures, an opening spaced from the first pair of apertures, and a second pair of apertures spaced from and disposed between the first pair of apertures and the opening, the first pair of apertures receiving the nasal pillows, the second pair of apertures aligned with the nasal pillows when the liner is in a folded configuration, and the opening aligned with the mouthpiece when the liner is in the folded configuration.

16. The liner of claim 15, wherein the first pair of apertures has a larger diameter than the second set of apertures.

17. The liner of claim 15, wherein the body comprises a single layer of material.

18. The liner of claim 15, wherein the material is stretchable.
