Abstract

A system for adjusting a gas delivery mask is provided. The system may include a base, an arm pivotally coupled to the base, and an intermediate member slidably coupled to both the base and the arm. The arm may include a first threaded portion, and the intermediate member may include a second threaded portion coupled to the first threaded portion. Rotation of the second threaded portion relative to the first threaded portion may slide the intermediate member along the arm and relative to the base such that the arm pivots relative to the base.

Claims

1. A system for adjusting a gas delivery mask, the system comprising:

a base;

an arm pivotally coupled to the base, the arm including a first threaded portion; and

an intermediate member slidably coupled to both the base and the arm, the intermediate member including a second threaded portion coupled to the first threaded portion, wherein rotation of the second threaded portion relative to the first threaded portion slides the intermediate member along the arm and relative to the base such that the arm pivots relative to the base.

2. A system according to claim 1, wherein the intermediate member comprises a sleeve disposed around the arm.

3. A system according to claim 1, wherein:

the base includes an elongated notch;

the intermediate member includes a peg slidably coupled to the elongated notch; and

rotation of the second threaded portion relative to the first threaded portion slides the peg along the elongated notch.

4. A system according to claim 1, wherein:

the base includes an elongated notch;

the intermediate member includes a body portion including a peg slidably coupled to the elongated notch; and

the second threaded portion is rotatably coupled to the body portion.

5. A system according to claim 1, wherein:

the intermediate member includes an elongated notch; and

the base includes a peg slidably coupled to the elongated notch.

6. A system according to claim 1, wherein rotation of the second threaded portion relative to the first threaded portion slides the intermediate member along the arm in a first direction and slides the intermediate member relative to the base in a second direction different from the first direction.

7. A system according to claim 1, wherein arm pivots relative to the base through an arc of between 10 degrees and 30 degrees.

8. A system according to claim 1, wherein arm pivots relative to the base through an arc of approximately 20 degrees.

9. A system according to claim 1, wherein:

the arm includes a notch extending along at least a portion of the length of the arm; and

the intermediate member includes a protrusion that slides within the notch as the intermediate member slides along the arm.

10. A system according to claim 1, wherein:

the threaded portion of the arm includes a thread member; and

the notch extends through the thread member.

11. A gas delivery mask apparatus, comprising:

a rigid mask base;

a face mask configured to deliver gas to the subject; and

a rigid mask arm rotationally coupled to the mask base proximate a first end by a pivot joint having an axis extending laterally across the mask base, the rigid mask arm coupled to the face mask proximate a second end and configured to support a flexible gas flow tube for delivering gas to the face masks;

wherein at least a portion of the flexible gas flow tube extends along a length of the rigid mask arm between the pivot joint and the face mask.

12. A mask apparatus according to claim 11, further comprising an intermediate member coupled to the mask base and the mask arm, wherein the intermediate member may be manipulated to rotate the mask arm about the pivot joint and relative to the mask base to vary a distance between the face mask and the subject'"'"'s face.

13. A mask apparatus according to claim 12, wherein the intermediate member comprises a sleeve disposed around the mask arm.

14. A mask apparatus according to claim 12, wherein:

the mask arm includes a first threaded portion; and

the intermediate member includes a second threaded portion coupled with the first threaded portion of the mask arm such that rotation of the second threaded portion relative to the first threaded portion rotates the mask arm about the pivot joint and relative to the mask base.

15. A mask apparatus according to claim 14, wherein rotation of the second threaded portion slides the intermediate member along the mask arm and relative to the mask base such that the mask arm pivots about the pivot joint and relative to the mask base.

16. A mask apparatus according to claim 14, wherein:

the mask base includes an elongated notch; and

the intermediate member includes a peg slidably coupled to the elongated notch.

17. A mask apparatus according to claim 16, wherein rotation of the second threaded portion relative to the first threaded portion slides the peg along the elongated notch.

18. A mask apparatus according to claim 14, wherein:

the intermediate member includes an elongated notch; and

the mask base includes a peg slidably coupled to the elongated notch.

19. A mask apparatus according to claim 14, wherein rotation of the second threaded portion relative to the first threaded portion slides the intermediate member along the mask arm in a first direction and slides the intermediate member relative to the mask base in a second direction different from the first direction.

20. A gas delivery mask, comprising:

a mask base;

a mask arm rotationally coupled to the mask base and including a first threaded portion; and

an intermediate mask member coupled to the mask base and the mask arm, the intermediate mask member including a second threaded portion coupled with the first threaded portion of the mask arm such that rotation of the second threaded portion relative to the first threaded portion rotates the mask arm relative to the mask base.

21. The mask of claim 20, wherein rotation of the second threaded portion slides the intermediate mask member along the arm and relative to the base such that the arm pivots relative to the base.

22. A system for adjusting a gas delivery mask, the system comprising:

rigid base means for supporting a gas delivery mask adjacent a subject'"'"'s head;

gas delivery means for delivering gas to the subject;

elongated rigid supporting means for supporting the gas delivery means, the rigid supporting means being rotatably coupled to the rigid base means about a pivot joint having an axis extending laterally across the rigid base means; and

rotating means having a first portion slidably coupled to the elongated rigid supporting means such that rotation of the rigid supporting means causes the first portion of the rotating means to slide along a length of the elongated rigid supporting means.

23. A system according to claim 22,

wherein the rotating means includes a second portion slidably coupled to the rigid base means.

24. A breathing facilitation system for facilitating or affecting a subject'"'"'s breathing, comprising:

a gas source configured to deliver gas;

an adjustable mask apparatus; and

one or more gas delivery conduits configured to deliver gas from the gas source to a subject via the adjustable mask apparatus;

wherein the adjustable mask apparatus comprises;

a base;

an arm pivotally coupled to the base, the arm including a first threaded portion; and

an intermediate member slidably coupled to both the base and the arm, the intermediate member including a second threaded portion coupled to the first threaded portion, wherein rotation of the second threaded portion relative to the first threaded portion slides the intermediate member along the arm and relative to the base such that the arm pivots relative to the base.
