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. A method for manufacturing an air delivery conduit for conveying pressurized gas from a positive airway pressure device to a patient interface for treatment of sleep disordered breathing, comprising:
manipulating a plurality of threads to form a tubular shaped air delivery conduit configured to convey the pressurized gas to the patient interface for treatment of sleep disordered breathing;
structuring the air delivery conduit to include a tubular wall structure comprising textile material,
wherein at least a portion of the wall structure comprising the textile material is configured to directly convey the pressurized gas and forms an outer surface disposed so as to be exposed directly to ambient air, and
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.
2. The method of claim 1 , wherein the step of manipulating a plurality of threads includes:
providing a warp having a plurality of lengthwise warp threads arranged in a circle;
providing a weft having a weft thread; and
weaving the weft thread through the plurality of warp threads in a circular weaving technique to produce the tubular wall structure.
3. The method of claim 2 , wherein the warp is constructed from flexible threads.
4. The method of claim 1 , wherein the reinforcing member comprises nylon.
5. The method of claim 1 , wherein the reinforcing member is constructed of plastic.
6. The method of claim 1 , wherein at least a portion of the reinforcing member is made of a semi-rigid material.
7. The method of claim 1 , wherein the textile material is a non-porous, woven textile material.
8. The method of claim 1 , wherein the textile material is a porous, woven textile material.
9. The method of claim 8 , wherein the porous textile material is treated thereby causing the textile material to become substantially nonporous.
10. The method of claim 1 , wherein the step of manipulating a plurality of threads includes manipulating the plurality of threads according to a circular textile- manufacturing technique configured to form the tubular shaped air delivery conduit without seams.
11. The method of claim 1 , wherein the textile material comprises resin.
12. The method of claim 1 , wherein a surface of the textile material has a thin film thereon.
13. The method of claim 1 , wherein the wall structure is arranged to be impermeable to gas.
14. The method of claim 13 , wherein the reinforcing member includes a spiral or helical shape.
15. The method of claim 13 , wherein the reinforcing member includes a spiral or helical shape and is attached to the wall structure.
16. The method of claim 1 , wherein the wall structure comprises a gas impermeable inner layer.
17. The method of claim 1 , wherein a surface of the textile material has a gas impermeable material provided thereon.
18. The method of claim 17 , wherein the surface of the textile material is an inner surface.
19. The method of claim 1 , wherein the tubular wall structure is a seamless tubular wall structure comprising the textile material.
20. The method of claim 19 , wherein an inner surface of the textile material has a gas impermeable material provided thereon, and
wherein the reinforcing member includes a spiral or helical shape.
