摘要：
A respiratory apparatus for delivering breathable gas to a patient includesa flow generator (20) that generates a supply of pressurised gas to be deliveredto the patient； a humidifier (1) for vaporising water and delivering water vaporto humidify the gas； a gas flow path leading from the flow generator to the humidifierand from the humidifier to a patient interface (5)； and a heater in thermal contactwith the gas and/or the water, wherein the heater (16) comprises an elongate heatingfilament in the form of a tape. A humidifier for respiratory apparatus includesa first respiratory gas passage (10) for receiving gas from a flow generator,a humidifier chamber, a second respiratory gas passage (4) for delivering humidifiedgas to a patient interface (5), and a heater in thermal contact with the gas and/orthe water, wherein the heater comprises an elongate heating filament (18, 19)extending along at least part of both said first and second respiratory gas passages.A conduit for use in a respiratory apparatus for delivering breathable gas toa patient includes a tube (4)； a helical rib (4b) on an outer surface of the tube；and a plurality of wires (4c, 4d, 4e) supported by the helical rib in contact withthe outer surface of the tube.
