Abstract:
An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

Claim (Index 21):
A mask system to deliver respiratory therapy to a patient, the mask system comprising:\n a patient interface that defines a breathing chamber and is shaped to seal against a face of the patient and deliver pressurized air from the breathing chamber into airways of the patient, the patient interface defining a first passage for introduction of pressurized air into the breathing chamber at a first lateral side of the patient interface and a second passage for introduction of pressurized air into the breathing chamber at a second lateral side of the patient interface that opposes the first lateral side of the patient interface; a first conduit to introduce pressurized air into the breathing chamber of the patient interface through the first passage, the first conduit structured to engage against a first side of a head of the patient, the first conduit having a D-shaped cross-sectional shape such that a relatively flat, inwardly-facing portion of the D-shaped cross-sectional shape of the first conduit is oriented to sit substantially flush against the face of the patient during use while a curved, outwardly-facing portion of the D-shaped cross-sectional shape of the first conduit is oriented away from the face of the patient during use; and a second conduit to introduce pressurized air into the breathing chamber of the patient interface through the second passage, the second conduit structured to engage against a second side of the head of the patient, the second conduit having the same D-shaped cross-sectional shape as the first conduit such that a relatively flat, inwardly-facing portion of the D-shaped cross-sectional shape of the second conduit is oriented to sit substantially flush against the face of the patient during use while a curved, outwardly-facing portion of the D-shaped cross-sectional shape of the second conduit is oriented away from the face of the patient during use.
