摘要：
The useful model refers to medicine, in particular to neurology and anesthesiology, and can be used in devices for inhalation therapy, as well as anesthesia apparatus in which it is required to form a binary respiratory mixture with prescribed concentrations of oxygen and a second gas.The technical result is the ability to determine the concentration of one of the gases: xenon, helium, nitrous oxide, krypton in the binary mixture "measured gas-oxygen" with an accuracy of not less than 0.1% for a time not exceeding 1 s, as well as convenience in operation, absence requirements for high qualification of personnel and reduction of the risk of mechanical damage.The gas concentration sensor in the "measured gas-oxygen" binary mixture consists of a casing (1), on two opposite sides of which there are two fittings (2) for mounting the device into the breathing circuit, and the third - an output cable (3) for connection to the unit (4) of the first gas, which consists of a thermoconductive sensing element, a heater and a thermometer, and on the opposite side of the sensor (4) there is a sensor for the concentration of ki (5), both sensors (4) and (5) are connected to the signal amplifier assembled on the printed circuit board (6), and the heater and the thermometer of the first gas concentration sensor (4) are connected to the heating control and thermostabilization control circuit assembled on the same a printed circuit board (6),Полезная модель относится к медицине, в частности к неврологии и анестезиологии, и может быть использована в аппаратах для ингаляционной терапии, а также наркозных аппаратах, в которых требуется формировать бинарную дыхательную смесь с заданными концентрациями кислорода и второго газа.Технический результат - возможность определять концентрацию одного из газов: ксенон, гелий, закись азота, криптон в бинарной смеси "измеряемый газ -кислород" с точностью не ниже 0,1% за время, не превышающее 1 с, а также удобство в эксплуатации, отсутствие требования
