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 comprising a sealing portion 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 and configured to suspend the patient interface on the patient'"'"'s face without any hard parts in a manner that maintains a sealed air path between the patient interface and the patient'"'"'s nose,

wherein the sealing portion of the patient interface extends through an aperture in the suspension system so that the suspension system supports the patient interface.

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 adhesive layer is configured to be supported on the patient'"'"'s nasal bridge, and wherein the patient interface is configured to only seal under the patient'"'"'s nose and is suspended from the adhesive layer by the suspension system.

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 1, wherein the patient interface and the adhesive layer are configured to engage different portions of the patient'"'"'s face when the patient interface system is mounted on the patient'"'"'s face.

10. A patient interface system according to claim 1, wherein a rim of the aperture supports the patient interface.

11. A patient interface system according to claim 1, wherein the patient interface and the suspension system are removably attached to each other.

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

a patient interface comprising a sealing portion 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 patient interface and configured to suspend the patient interface on the patient'"'"'s face in a manner that maintains a sealed air path between the patient interface and the patient'"'"'s nose,

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

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, and

wherein the sealing portion of the patient interface extends through an aperture in the suspension system so that the suspension system supports the patient interface.

13. A patient interface system according to claim 12, wherein the patient interface system does not include polycarbonate material.

14. A patient interface system according to claim 12, 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.

15. A patient interface system according to claim 14, wherein the primary headgear is configured to be supported on the patient'"'"'s nasal bridge.

16. A patient interface system according to claim 15, wherein the primary headgear comprises the aperture through which said sealing portion of the patient interface extends.

17. A patient interface system according to claim 16, wherein the primary headgear wraps around the patient interface in a sling-like fashion.

18. A patient interface system according to claim 12, wherein the patient interface system does not include a hard shell or frame.

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

a patient interface comprising a sealing portion 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 and configured to suspend the patient interface on the patient'"'"'s face in a manner that maintains a sealed air path between the patient interface and the patient'"'"'s nose,

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

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

wherein the sealing portion of the patient interface extends through an aperture in the suspension system so that the suspension system supports the patient interface.

20. A patient interface system according to claim 19, 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.

21. A patient interface system according to claim 20, wherein the patient interface comprises elastomeric material.

22. A patient interface system according to claim 21, wherein the primary headgear comprises a flexible composite material.

23. A patient interface system according to claim 22, wherein the flexible composite material comprises at least one of laminated foam, nonwoven fabric and mesh.

24. A patient interface system according to claim 19, 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.
