Abstract: A heated conduit is configured to be connected to and receive pressurized breathable gas from a respiratory unit. The heated conduit includes a first cuff configured to be attached to the respiratory unit, the first cuff comprising a tubular air inlet portion that is configured to receive the pressurized breathable gas and an electrical connector portion that is adjacent to the tubular air inlet portion and comprises three electrical terminals. The three electrical terminals are configured to engage an electrical connector of the respiratory unit. A grouping of wires are supported within a helical rib of a flexible tube portion. The grouping of wires includes a pair of heating wires configured to generate heat and a signal wire configured to carry the signal that is output by a sensing device. Each of the heating wires and the signal wire is connected to a corresponding one of the three electrical terminals of the electrical connector portion of the first cuff.

Abstract: A user interface for respiratory apparatus comprises a combination of a menu display (302), push buttons (304, 308, 310) and a rotary control dial (306). The user interface may include a menu control for detecting at least one parameter from the user's operation of the controls to navigate the menu and applying this to subsequent operation of the user interface controls. The user parameter may be a direction of operation of the rotary control dial which the user associates with a particular direction of navigation within the menu.

Abstract: An air delivery tube for a CPAP system includes a first end configured to connect to a flow generator of the CPAP system and a second end configured to connect to a patient interface of the CPAP system. The air delivery tube also includes a central lumen that is formed by an inner wall of the air delivery tube and is configured to convey pressurized breathable gas from the first end to the second end. In addition, a circumferential chamber surrounds the central lumen and is configured to retain a supply of water. A wick is located within the central lumen and is connected to the inner wall.
