Abstract

A patient interface includes a sealing arrangement adapted to provide an effective seal with the patient'"'"'s nose, an inlet conduit arrangement adapted to deliver breathable gas to the sealing arrangement, and a cover that substantially encloses the sealing arrangement and/or the inlet conduit arrangement.

Claims

1. A patient interface comprising:

a sealing arrangement adapted to provide an effective seal with the patient'"'"'s nose, the sealing arrangement including a shell and a seal provided to the shell, and the seal includes a foam material arranged to contact the patient'"'"'s nose;

an inlet conduit arrangement provided to the shell and adapted to deliver pressurized, breathable gas to the sealing arrangement, the inlet conduit arrangement including at least one enclosed conduit passageway along which the breathable gas can travel toward the sealing arrangement; and

a cover constructed of a textile material that encloses at least a portion of the shell, the cover at least partially forming the inlet conduit arrangement or enclosing at least a portion of the at least one enclosed conduit passageway.

2. A patient interface according to claim 1, wherein the seal includes a textile material.

3. A patient interface according to claim 2, wherein the seal includes one or more layers of textile material.

4. A patient interface according to claim 1, wherein the seal is in the form of a nasal cushion.

5. A patient interface according to claim 1, wherein the seal includes a leaky seal to allow breathing, avoid moisture, or allow gas washout.

6. A patient interface according to claim 1, wherein the shell includes a semi-rigid, hinged, or bendable shell.

7. A patient interface according to claim 1, wherein the cover is inflatable so as to form the inlet conduit arrangement.

8. A patient interface according to claim 7, wherein the inlet conduit arrangement includes two conduits configured to extend respectively along opposite sides of the patient'"'"'s face.

9. A patient interface according to claim 1, further comprising a strap provided to the cover and configured to secure the patient interface on the patient'"'"'s face.

10. A patient interface according to claim 1, wherein the foam material is configured to contact the patient'"'"'s nose below and adjacent a tip of the patient'"'"'s nose.

11. A patient interface according to claim 1, wherein the cover substantially encloses the entire shell.

12. A patient interface according to claim 1, wherein the inlet conduit arrangement includes two inlet conduits, and the inlet conduits are adapted to engage respective end portions of the shell to deliver breathable gas to the respective end portions of the shell.
