Textile tube for a therapy device

An apparatus for providing positive pressure respiratory therapy to a patient breathing in a respiratory cycle including an inhalation portion and an exhalation portion, said apparatus comprising:

• a controllable motor-blower configured to generate a supply of air at a positive pressure relative to ambient pressure by rotating an impeller at an impeller speed,
• a housing holding said motor-blower, the housing comprising an inlet and a patient-connection port, the patient-connection port being structured to communicate said supply air at said positive pressure from the motor-blower to a patient interface via an air circuit in use;
• a sensor to monitor at least one of pressure and a flow rate of the supply of air at positive pressure and to generate a sensor output;
• and
• a controller configured to adjust an operating parameter of said motor-blower in accordance with said sensor output to maintain a minimum positive pressure in said patient interface during a treatment session by causing an increase in the impeller speed during the inhalation portion of the respiratory cycle and causing a decrease in the impeller speed during the exhalation portion of the respiratory cycle,
• the air circuit comprising:
• a tubular structure;
• the tubular structure having a circular woven structure;
• the tubular structure being seamless along a length of the tubular structure;
• the tubular structure including a plurality of warp threads and a plurality of weft threads;
• the plurality of weft threads including a first monofilament weft thread and a second monofilament weft thread;
• the first monofilament weft thread being located adjacent to at least one non-monofilament weft thread, the second monofilament weft thread also being located adjacent to at least one non-monofilament thread;
• and
• wherein the at least one non-monofilament thread is located between the first monofilament weft thread and the second monofilament weft thread.
