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. |
