摘要：The invention relates to an oxygen therapy device for high-flow oxygen therapy.The oxygen therapy device comprises a nose part (1) comprising a gas channel for apatient gas and two nasal cannulae (7) in fluid communication with the gas channel, eachhaving a patient gas outlet opening, a gas distribution device (3 ) for connection to apatient gas source and at least one molding tube (5), comprising a gas channel (11)opening into a gas inlet opening and a gas outlet opening of the molding tube (5), themolding tube (5) with its gas outlet opening into a gas inlet opening (9) of the nose part(1) and with its gas inlet opening into a gas outlet opening of the gas distribution device(3) opens. The molding tube (5) has a cross-sectional shape of its gas channel (11) whichdeviates from the shape of a circle and an ellipse. In addition, the oxygen therapy devicecomprises at least one pressure control valve (8) which is adapted to open at least onevalve flap above a predetermined amount of the differential pressure between

atmospheric pressure and gas pressure in the gas distribution device (3) and / or the nosepart (1), wherein an opening degree of the valve flap proportional to the differentialpressure.
