Abstract

A patient interface device includes a headgear component having a first end, a second end, and a sealing interface region located between the first end and the second end, wherein the sealing interface region has a hole extending through the elongated fabric body member. The patient interface device also includes a mask component having a cushion and a fluid coupling conduit fluidly coupled to the cushion, wherein at least a portion of the fluid coupling conduit extends through the hole and the sealing interface region covers at least a portion of the cushion. The cushion will be held and supported by the elongated fabric body member in engagement with a portion of the patient'"'"'s face responsive to the patient interface device being donned by the patient by wrapping the elongated fabric body member around the head of the patient.

Claims

1. A patient interface device, comprising:

a headgear component including an elongated fabric body member structured to wrap around a head of a patient, the elongated fabric body member having a first end, a second end and a sealing interface region located between the first end and the second end, the sealing interface region having a hole extending through the elongated fabric body member;

a mask component having a cushion; and

a fluid coupling conduit fluidly coupled to the cushion, wherein at least a portion of the fluid coupling conduit extends through the hole and the sealing interface region covers at least a portion of the cushion, and wherein the cushion will be held and supported by the elongated fabric body member in engagement with a portion of the patient'"'"'s face responsive to the patient interface device being donned by the patient by wrapping the elongated fabric body member around the head of the patient.

2. The patient interface device according to claim 1, wherein the elongated fabric body member includes a rear surface and a front surface, the headgear component further comprising a first stabilizing region provided on the rear surface adjacent to a first side of the sealing interface region, and a second stabilizing region provided on the rear surface adjacent to a second side of the sealing interface region opposite the first side, wherein the first and second stabilizing regions each have a structure configured to engage the patient'"'"'s face and prevent the elongated fabric body member from sliding relative to the patient'"'"'s face when the patient interface device is donned by the patient.

3. The patient interface device according to claim 2, wherein the first and second stabilizing regions each comprise an elastomeric webbing.

4. The patient interface device according to claim 3, wherein each elastomeric webbing comprises a plurality of fibers of the elongated fabric body member coated with an elastomer coating.

5. The patient interface device according to claim 3, wherein the first stabilizing region comprises a first separate component attached to the elongated fabric body member, wherein the first separate component comprises a first fabric piece wherein a plurality of fibers of the first fabric piece are coated with an elastomer coating, and wherein the second stabilizing region comprises a second separate component attached to the elongated fabric body member, wherein the second separate component comprises a second fabric piece wherein a plurality of fibers of the second fabric piece are coated with an elastomer coating.

6. The patient interface device according to claim 1, wherein the first end includes a first elastomeric webbing portion and the second end includes a second elastomeric webbing portion.

7. The patient interface device according to claim 6, wherein each elastomeric webbing portion comprises a plurality of fibers of the elongated fabric body member coated with an elastomer coating.

8. The patient interface device according to claim 6, wherein the elongated fabric body member includes a rear surface and a front surface, wherein the first elastomeric webbing portion comprises a first rear webbing portion provided on the rear surface and a first front webbing portion provided on the front surface, and wherein the second elastomeric webbing portion comprises a second rear webbing portion provided on the rear surface and a second front webbing portion provided on the front surface.

9. The patient interface device according to claim 1, wherein the elongated fabric body member comprises a flat body member.

10. The patient interface device according to claim 1, wherein the elongated fabric body member comprises a tubular body member.

11. The patient interface device according to claim 10, wherein the tubular body member includes a rear surface and a front surface, wherein the hole is provided in the front surface, wherein a second hole is provided in the rear surface in the sealing interface region, wherein at least a portion of the mask component is held in between the rear surface and the front surface, and wherein at least a portion of the cushion extends outwardly through the second hole.

12. The patient interface device according to claim 1, wherein the sealing interface region is located midway between the first end and the second end.

13. The patient interface device according to claim 1, wherein the elongated fabric body member includes a rear surface and a front surface, wherein the sealing interface region is located adjacent to the first end, wherein the second end includes a first fastening system component provided on the rear surface, wherein a second fastening system component is provided on the front surface adjacent to the sealing interface region, and wherein the second end is structured to cover the sealing interface region and the first fastening system component is structured to engage the second fastening system component when the elongated fabric body member is wrapped around the head of the patient.

14. The patient interface device according to claim 13, wherein the first and second fastening system components are part of a hook and loop fastener system.

15. The patient interface device according to claim 13, further comprising a plurality of vent holes in the second end and in the sealing interface portion.

16. A method of securing a patient interface device to a head of a patient, the patient interface device including a mask component having a cushion and a fluid coupling conduit fluidly coupled to the cushion, the method comprising:

obtaining a headgear component including an elongated fabric body member structured to wrap around the head of the patient, the elongated fabric body member having a first end, a second end and a sealing interface region located between the first end and the second end, the sealing interface region having a hole extending through the elongated fabric body member;

inserting a portion of the fluid coupling conduit through the hole such that the sealing interface region covers at least a portion of the cushion;

positioning the cushion against a portion of the patient'"'"'s face; and

wrapping the elongated fabric body member around the head in a manner wherein the cushion will be held and supported by the elongated fabric body member in engagement with the portion of the patient'"'"'s face.

17. The method according to claim 16, further comprising securing the first end and the second end together.

18. The method according to claim 17, wherein the securing the first end and the second end together comprises tying a knot between the first end and the second end.

19. The method according to claim 17, wherein the first end includes a first elastomeric webbing portion and the second end includes a second elastomeric webbing portion, and wherein the securing the first end and the second end together comprises twisting the first end and the second end together to cause the first and second elastomeric webbing portions to adhere to one another.

20. The method according to claim 16, wherein the elongated fabric body member includes a rear surface and a front surface, the headgear component further comprising a first stabilizing region provided on the rear surface adjacent to a first side of the sealing interface region, and a second stabilizing region provided on the rear surface adjacent to a second side of the sealing interface region opposite the first side, wherein the first and second stabilizing regions each comprise an elastomeric webbing.
