Abstract: A flexible tape heater (110) in a patient conduit (112) may be used to heat the flow of gas in the patient conduit (112) that is delivered to the patient mask (116). The thin, flat and extended nature of the flexible tape heater (110) may enhance heat transfer with the gas flow whilst also providing low impedance to the gas flow. Heating of the gas may facilitate the desired temperature and humidity to be reached for the gas delivered to the patient by the respiratory apparatus. The flexible tape heater (110) may be placed in the patient conduit (112) such that the flexible tape heater (110) is twisted or bent about one or more of the flexible tape heater's (110) three axes. Additionally these configurations may be used to enhance the turbulent mixing of the water vapour produced in the humidification chamber (114) with the gas flow.

Abstract: A respiratory apparatus for delivering breathable gas to a patient includes a flow generator that generates a supply of pressurised gas to be delivered to the patient; a humidifier for vaporising water and delivering water vapor to humidify the gas; a gas flow path leading from the flow generator to the humidifier and from the humidifier to a patient interface; and a heater in thermal contact with the gas and/or the water, wherein the heater comprises an elongate heating filament in the form of a tape. A humidifier for respiratory apparatus includes a first respiratory gas passage for receiving gas from a flow generator, a humidifier chamber, a second respiratory gas passage for delivering humidified gas to a patient interface, and a heater in thermal contact with the gas and/or the water, wherein the heater comprises an elongate heating filament 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 to a patient includes a tube; a helical rib on an outer surface of the tube; and a plurality of wires supported by the helical rib in contact with the outer surface of the tube.
