Abstract: A heated conduit is configured to connect to and receive pressurized breathable gas from a respiratory unit. The heated conduit includes a first cuff that includes an air inlet portion and an electrical connector portion that is adjacent the air inlet portion and comprises three electrical terminals that are configured to engage a respiratory unit electrical connector. The heated conduit also includes a second cuff comprising an air outlet and a flexible tube portion with a first end connected to the first cuff, a second end connected to the second cuff, and a spiral rib structure wrapped around a central lumen. A grouping of wires is supported within the spiral rib structure of the flexible tube portion and include a pair of heating wires and a signal wire. A sensing device extends into the gas flow path from an interior surface of the second cuff and is configured to output a signal indicative of the condition inside the heated conduit.

Abstract: A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.

Abstract: A flow generator includes a blower, a flow generator outlet configured to receive an end of a gas delivery tube, and a controller. The flow generator outlet includes electrical connectors configured to contact corresponding electrical connectors associated with the breathable gas delivery tube when the breathable gas delivery tube is received by the flow generator outlet. The controller includes a tube-type detect circuit and is configured to receive signals from the breathable gas delivery tube by way of the electrical connectors of the flow generator outlet. The tube-type detect circuit is configured so that when the breathable gas delivery tube is received by the flow generator outlet, the tube-type detect circuit determines the type of breathable gas delivery tube based on signals from the electrical connectors of the flow generator outlet that are indicative of a condition of a resistor associated with the breathable gas delivery tube.

Abstract: A flow generator and humidifier construction is described, including a flow generator construction adapted to reduce noise output compared to known flow generators of comparable size. The flow generator includes a chassis forming first and second muffler volumes and a venturi-shaped connection portion, and a metal/polymer composite material blower enclosure which suppresses noise from the blower. The flow generator may be programmed to include a reminder system including a menu from which the user may request a reminder to take specific action, e.g., replace a component, call a physician, and/or enter patient data card, etc.
