PROBLEM TO BE SOLVED: To provide a respiratory apparatus for delivering breathable gas to a patient.SOLUTION: The respiratory apparatus includes: a flow generator that generates a supply of pressurized gas to be delivered to the patient; a humidifier for vaporizing 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, where the heater comprises a heating filament in the form of a tape. A humidifier for a 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, where the heater comprises an elongate heating filament extending along at least part of both the 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. 【課題】本発明は呼吸可能な気体を患者に送る呼吸装置を提供する。【解決手段】上記呼吸装置は、患者に送られる供給量の加圧気体を発生する流量発生器と、水を蒸発させ水蒸気を送出して気体を加湿する加湿器と、流量発生器から加湿器に及び加湿器から患者インターフェイスに至る気体流路と、テープ形態の加熱用フィラメントを含んで気体及び／又は水と熱接触する加熱器とを含む。呼吸装置の加湿器は、流量発生器から気体を受ける第１呼吸用気体通路と、加湿器室と、加湿気体を患者インターフェイスに送る第２呼吸用気体通路と、第１及び第２呼吸用気体通路双方の少なくとも一部に沿って延在する細長い加熱用フィラメントを含んで気体及び／又は水と熱接触する加熱器とを含む。呼吸可能な気体を患者に送る呼吸装置に用いる導管は、チューブと、チューブ外面上にある螺旋状リブと、チューブ外面に接する螺旋状リブによって支持された複数の配線とを含む。【選択図】図２２
