Delivery of respiratory therapy
First Claim
1. An air delivery system for providing a supply of air from a source of air at positive pressure to a patient, the air delivery system comprising:
- an interfacing structure located at the entrance to the airways of the patient; and
at least one tube adapted to deliver the supply of air to the interfacing structure, wherein each tube has at least one portion that is structured to allow movement between (1) an open phase in which the tube allows the flow of air without undue resistance and (2) at least a partially collapsed phase in which the tube is at least partially collapsed to restrict or prevent the flow of air, and each tube is structured such that the weight of a typical patient'"'"'s head resting on the tube is sufficient to collapse the tube from the open phase to the at least partially collapsed phase.

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.

6. A gas delivery system for providing a supply of gas from a source of gas at positive pressure to an interfacing structure located at an entrance to the airways of a patient, the gas delivery system comprising:
-
at least two gas passages adapted to be in communication with the source of gas to deliver the supply of gas to the interfacing structure, the at least two gas passages structured and configured to cooperate such that pressurized gas from the source of gas is delivered to the interfacing structure via one or both of the gas passages even if one of the gas passages assumes an at least partially collapsed configuration, wherein each of the passages has at least one portion structured for movement between (1) an open configuration in which the passage allows the flow of gas and (2) an at least partially collapsed configuration in which the passage is at least partially collapsed, and each passage is structured such that the weight of a patient'"'"'s head applied to one of the passages is sufficient to cause that passage to move or deform from the open configuration to the at least partially collapsed configuration. - View Dependent Claims (7, 8)

9. 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, the air delivery system comprising:
-
a manifold adapted to connect with the supply of positive air pressure; and at least one tube connected to the manifold and is adapted to deliver the supply of air to the interfacing structure, wherein each tube is structured to allow movement between (1) an open phase in which the tube allows the passage of air and (2) a collapsed phase in which the tube is collapsed, and 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. An air delivery and stabilizing 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, the air delivery system comprising:
-
a manifold adapted to connect with the supply of positive air pressure; a pair of tubes connected to the manifold and adapted to deliver the supply of air to the interfacing structure, each tube adapted to extend from a respective side of the manifold at or in front of the crown of the patient'"'"'s head, along a respective side of the patient'"'"'s face between the patient'"'"'s eye and ear, and under the patient'"'"'s nose; a rigidizing element provided to each tube to add rigidity to the tube; and a back strap provided to the tubes and/or rigidizing elements and adapted to engage the back of the patient'"'"'s head, wherein each tube is structured to allow movement between (1) an open phase in which the tube allows the passage of air and (2) a collapsed phase in which the tube is collapsed, and 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. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
