摘要:
A respiratory interface device includes a mask, a connector tubing component, a headgear and a tube management device coupled to the headgear. The connector tubing component has a main tubing portion and a swivel mechanism provided at an end thereof for coupling the connector tubing component to a gas supply tube. The main tubing portion of the connector tubing component is structured to be moveably received within and held by the tube management device. The pressure applied to the bridge of the nose of the user by the mask may be selectively adjusted by adjusting the position of the main tubing portion within the tube management device. The tube management device may, for example, be threaded, employ a friction fit, employ a cam mechanism, or employ a compressible tube attachment piece, among other implementations.

An exhaust port assembly comprising a conduit carries a flow of gas. A vent assembly having a fixed exhaust area is provided on the conduit for venting a flow of exhaust gas from within the conduit to ambient atmosphere. The vent assembly is configured so as to minimize noise associated with the flow of exhaust gas passing to atmosphere, diffuse the flow of exhaust gas passing to ambient atmosphere over a relatively large area, and minimize the area occupied by the venting assembly on the conduit.
