Abstract

A patient interface system includes a nasal seal of flexible material to communicate with at least one airway of the patient, and a primary headgear from which the nasal seal is suspended, said primary headgear having at least one aperture though which at least a portion of the nasal seal is inserted with the primary headgear wrapping about at least one portion of the nasal seal in a sling-like fashion.

Claims

1. A patient interface system configured to deliver pressurized breathable gas to a patient'"'"'s airways, the patient interface system comprising:

a patient interface configured to sealingly engage a patient'"'"'s nose when the patient interface system is mounted on the patient'"'"'s face; and

a suspension system with an adhesive layer configured to be adhered to the patient'"'"'s face, the suspension system being connected to the patient interface to suspend the patient interface on the patient'"'"'s face without any hard parts in a manner that maintains a seal between the patient interface and the patient'"'"'s nose.

2. A patient interface system according to claim 1, wherein the patient interface system does not include polycarbonate material.

3. A patient interface system according to claim 1, wherein the suspension system comprises an adhesive pad adapted to be positioned on the patient'"'"'s face and a primary headgear connecting the patient interface to the suspension system.

4. A patient interface system according to claim 3, wherein the patient interface comprises elastomeric material.

5. A patient interface system according to claim 4, wherein the primary headgear comprises a flexible composite material.

6. A patient interface system according to claim 5, wherein the flexible composite material comprises at least one of laminated foam, nonwoven fabric and mesh.

7. A patient interface system according to claim 1, wherein the suspension system is configured to be supported on the patient'"'"'s nasal bridge.

8. A patient interface system according to claim 7, wherein the suspension system is configured to wrap around the patient'"'"'s nose in a sling-like fashion.

9. A patient interface system according to claim 8, wherein the suspension system comprises an aperture through which a portion of the patient interface extends.

10. A patient interface system configured to deliver pressurized breathable gas to a patient'"'"'s airways, the patient interface comprising:

a patient interface configured to sealingly engage a patient'"'"'s nose when the patient interface system is mounted on the patient'"'"'s face; and

a suspension system with an adhesive portion configured to be adhered to the patient'"'"'s face, the suspension system being connected to the patient interface to suspend the patient interface on the patient'"'"'s face in a manner that maintains a seal between the patient interface and the patient'"'"'s nose,

wherein the patient interface and the suspension system do not include any hard parts, and

wherein hard parts are unbendable parts or are bendable parts that retain their bent shape at room temperature in the absence of force acting on the hard part.

11. A patient interface system according to claim 10, wherein the patient interface system does not include polycarbonate material.

12. A patient interface system according to claim 10, wherein the suspension system comprises an adhesive pad adapted to be positioned on the patient'"'"'s face and a primary headgear connecting the patient interface to the suspension system.

13. A patient interface system according to claim 12, wherein the primary headgear is configured to be supported on the patient'"'"'s nasal bridge.

14. A patient interface system according to claim 13, wherein the primary headgear comprises an aperture through which a portion of the patient interface extends.

15. A patient interface system according to claim 14, wherein the primary headgear wraps around the portion of the patient interface in a sling-like fashion.

16. A patient interface system according to claim 10, wherein the patient interface system does not include a hard shell or frame.

17. A patient interface system configured to deliver pressurized breathable gas to a patient'"'"'s airways, the patient interface comprising:

a patient interface configured to sealingly engage a patient'"'"'s nose when the patient interface system is mounted on the patient'"'"'s face; and

a suspension system with an adhesive portion configured to be adhered to the patient'"'"'s face, the suspension system being connected to the patient interface to suspend the patient interface on the patient'"'"'s face in a manner that maintains a seal between the patient interface and the patient'"'"'s nose,

wherein the patient interface and the suspension system do not include any hard parts, and

wherein the materials comprising the patient interface and the suspension system include only materials that are soft, compliant and flexible.

18. A patient interface system according to claim 17, wherein the suspension system comprises an adhesive pad adapted to be positioned on the patient'"'"'s face and a primary headgear connecting the patient interface to the suspension system.

19. A patient interface system according to claim 18, wherein the patient interface comprises elastomeric material.

20. A patient interface system according to claim 19, wherein the primary headgear comprises a flexible composite material.

21. A patient interface system according to claim 20, wherein the flexible composite material comprises at least one of laminated foam, nonwoven fabric and mesh.

22. A patient interface system according to claim 17, wherein the patient interface and the suspension system are configured to inter-engage and/or interlace with one another without requiring a hard frame or shell and without requiring one or more separate clips.
