Air delivery conduit
An air delivery conduit for conveying breathable gas from a positive airway pressure device to a patient interface includes a tubular wall structure constructed from a textile material. A reinforcing structure may be provided to the wall structure that is structured to prevent kinking or collapsing of the wall structure. The wall structure may include a warp having a plurality of lengthwise textile warp threads arranged in a circle and a weft having a textile weft thread that is woven through the warp threads.
1. An air delivery system for treatment of sleep disordered breathing by providing pressurized gas to a patient's airways, by way of a patient interface, the air delivery system comprising:
the patient interface; and
a conduit configured to convey the pressurized air to the patient interface for treatment of sleep disordered breathing,
wherein the conduit includes a tubular wall structure comprising textile material,
wherein at least a portion of the wall structure comprising the textile material directly conveys the pressurized air and forms an outer surface disposed so as to be exposed directly to ambient air,
wherein the conduit includes a non-metallic reinforcing member disposed on the outer surface of the wall structure and configured to prevent collapse of the wall structure.
