Claims

1. A conduit assembly adapted to deliver a flow of breathing gas to an airway of user comprising:
a first flexible segment having a first end portion, a second end portion, and a first lumen defined therein from the first end portion to the second end portion;
a second flexible segment having a third end portion, a fourth end portion, and a second lumen defined therein from the third end portion to the fourth end portion; and
a first swivel connector adapted to be coupled to the second end portion of the first segment and the third end portion of the second segment such that the first segment is rotatable relative the second segment.
2. The conduit assembly of claim 1, wherein the first end portion of the first segment is adapted to be coupled to an outlet of a pressure support device.
3. The conduit assembly of claim 1, wherein the fourth end portion of the second segment is adapted to be coupled to a patient interface.
4. The conduit assembly of claim 3, wherein the fourth end portion of the second segment is adapted to be coupled to a coupling member associated with the patient interface.
5. The conduit assembly of claim 3, wherein the fourth end portion of the second segment is rotatably coupled to the patient interface.
6. The conduit assembly of claim 1, wherein the first segment and the second segment include a flexible member and a helical support disposed around the flexible member.
7. The conduit assembly of claim 1, wherein the swivel connector includes:
a first portion rigidly coupled to the second end portion of the first segment, and
a second portion rigidly coupled to the third end portion of the second segment, wherein the first portion is rotatably coupled to the second portion.
8. The conduit assembly of claim 1, further comprising a heating element associated with the first segment, the second segment, or both.
9. The conduit assembly of claim 8, wherein the heading element comprises a heating wire disposed in the first lumen, the second lumen, or both.
10. A system for delivering a breathing gas to a user comprising:
(a) a gas flow/pressure generating device adapted to produce a flow of gas, the gas flow generating device having a housing and an outlet on an exterior of the housing;
(b) a patient interface assembly; and
(c) a conduit assembly having a first end portion operatively coupled to the outlet of the housing and a second end portion operatively coupled to the patient interface assembly, wherein the conduit assembly carries the flow of gas from the gas flow generating device during operation of the gas flow generating system, and wherein the conduit assembly comprises:
(1) a plurality of flexible segments; and
(2) a swivel connector disposed between and joining adjacent segments in the plurality of flexible segments such that adjacent flexible segments are rotatable relative to one another.
11. The system of claim 10, wherein the patient interface assembly comprises:
a shell having a first side and a second side;
a coupling member coupled to the first side of the shell; and
a cushion coupled to the second side of the shell, and wherein the second end portion of the conduit assembly is coupled to the coupling member.
12. The system of claim 11, wherein the coupling member is rotatably coupled to the shell, the second end portion of the conduit assembly is rotatably coupled to the coupling member, or both.
13. The system of claim 10, wherein the second end portion of the conduit assembly is rotatably coupled to the patient interface.
14. The system of claim 10, wherein each flexible segment in the plurality of flexible segments comprises a flexible member, and a helical support disposed around the flexible member.
15. The system of claim 10, wherein the swivel connector includes:
a first portion rigidly coupled to the second end portion of the first conduit, and
a second portion rigidly coupled to the third end portion of the second conduit, wherein the first portion is rotatably coupled to the second portion.
16. The system of claim 10, further comprising a heating element associated with on one or more of the plurality of flexible segments.
17. The system of claim 16, wherein the heading element comprises a heating wire disposed in one or more of the plurality of flexible segments.
18. The system of claim 10, wherein the plurality of flexible segments comprise three segments.
19. The system of claim 10, further comprising a humidifier chamber having an humidifier inlet and a humidifier outlet, wherein the humidifier inlet is operatively coupled to the outlet of the housing, and wherein the humidifier outlet is operatively coupled to the first end portion of the conduit assembly.
