Abstract
A conduit for delivering a supply of gas under a positive pressure includes a conduit wall having a first conduit end and a second conduit end. The first conduit end is adapted to be attached to the supply of gas. The conduit wall is deformable between (a) an open condition in which the conduit wall defines a conduit passage along which the supply of gas can travel between the first conduit end to the second conduit end, and (b) a collapsed condition in which the conduit wall substantially collapses the conduit passage.

-20. (canceled)
A nasal assembly for delivering breathable gas under positive pressure to a patient for treatment of sleep disordered breathing, the nasal assembly comprising:
- an air connector configured to deliver a supply of breathable gas, the air connector being adapted to be positioned on top of the patient's head when the nasal assembly is worn;
- a nasal interface configured to engage the patient's nose to direct the breathable gas to the patient's nose;
- a pair of flexible side portions configured to support the nasal interface in a desired position on the patient's face and to deliver the breathable gas to the nasal interface in use, each side portion providing a conduit having a top portion in fluid communication with the air connector and a bottom portion adapted to, in use, be positioned adjacent the patient's nose, each conduit being arranged to, in use, extend along a respective side of the patient's head between the patient's eye and ear;
- and
- a central portion integrally formed with the pair of side portions to join the top portions of the conduits, the central portion and the pair of side portions forming a unitary construction constructed of a same material;
- wherein the air connector is attached to the central portion,
- wherein the air connector is movably connected to the central portion, and
- wherein the nasal assembly further comprises a swivel coupling device rotatably mounted to the air connector, the swivel coupling device being adapted to connect to an air supply tube adapted to deliver the supply of breathable gas to the air connector.
A nasal assembly for delivering breathable gas under positive pressure to a patient for treatment of sleep disordered breathing, the nasal assembly comprising:
- an air connector configured to be connected to an air supply tube adapted to deliver a supply of breathable gas, the air connector being adapted to be positioned on top of the patient's head when the nasal assembly is worn;
- a nasal interface configured to engage the patient's nose to direct the breathable gas to the patient's nose;
- a pair of flexible side portions configured to support the nasal interface in a desired position on the patient's face and to deliver the breathable gas to the nasal interface in use, each side portion providing a conduit having a top portion in fluid communication with the air connector and a bottom portion adapted to, in use, be positioned adjacent the patient's nose, each conduit being arranged to, in use, extend along a respective side of the patient's head between the patient's eye and ear;
- a central portion integrally formed with the pair of side portions to join the top portions of the conduits, the central portion and the pair of side portions forming a unitary construction constructed of a same material;
- and
- wherein the air connector is attached to the central portion,
- wherein the air connector is pivotally connected to each of the supply tube and the central portion.
