Abstract
A delivery conduit (6A,6A′,6B,6C) for delivering a flow of gas in a respiratory therapy system (2) includes an elongated wall member (22,34) made of a textile material, and a support member (24, 36, 36′, 36″, 42, 50, 58, 64, 70) extending along at least a portion of the length of the wall member. The support member engages either the inner surface or the outer surface of the wall member, and engages less than the entirety of the inner surface or the outer surface of the wall member such that a plurality of portions of the wall member are not engaged by the support member and at the plurality of portions the wall member is the only barrier to the gas within the delivery conduit.
Claims28
A delivery conduit for delivering a flow of gas in a respiratory therapy system, comprising:
- an elongated wall member made of a textile material;
- and
- a support member extending along at least a portion of a length of the wall member and engaging either an inner surface or an outer surface of the wall member, wherein the support member engages less than an entirety of the inner surface or the outer surface of the wall member such that a plurality of portions of the wall member are not engaged by the support member and at the plurality of portions the wall member is the only barrier to the gas within the delivery conduit, the support member including a bonding agent structured to enable the support member to be fixedly attached to the wall member using a heat setting process, wherein the bonding agent is at least partly made of a material that is also included in the wall member such that the support member and the wall member are fused together as a result of the heat setting process.

(canceled)
A delivery conduit for delivering a flow of gas in a respiratory therapy system, comprising:
- a support structure;
- and
- a wall operatively coupled to the support structure such that at least a portion of the wall defines a passage adapted to carry the flow of gas, and wherein the support structure and the wall are structured and arranged such that the delivery conduit has at least one of (i) a bend radius to outer diameter ratio that is greater than or equal to 1.0 mm/mm and less than or equal to 1.67 mm/mm, and (ii) a mass to length ratio that is greater than or equal to 0.03 grams/mm and less than or equal to 0.06 grams/mm.
