摘要：
The invention relates to medicine, in particular, to neurology and anesthesiology, and can be used in devices for inhalation therapy, as well as anesthetic devices, which require maintaining a given composition of the respiratory gas mixture of oxygen and second gas in a closed respiratory circuit.The technical result is to provide the possibility of accurately maintaining the composition of the binary mixture “oxygen - second gas”, the safety of the procedure, as well as the reduction and accurate metering of the flow rate of the second gas.The gas dosing unit consists of a housing (1), inside which a pneumatic unit (2) is installed on the front side, on one side to which a gas flow regulator (4) is fixed, on the other hand a breathing gas pressure sensor (6), and above it - flow meter (7) on the bottom side of the housing (1) are located a single board computer (8) and a printed circuit board (9), which are interconnected by a high-speed wired interface, with the respiratory mixture pressure sensor (6) connected to the printed circuit board (9) using shielded cables using power stranded wires - flow control (4) on the back of the case (1) there is a cooling fan (10) inside, and outside - a 220 V power input (11) for powering the device, a power button (12), an HDMI output (13) for connecting a monitor, an output (14) for connecting an uninterrupted power supply, an output (15) for connecting the monitor power (15) and an output (16) for connecting a card reader, all of the above outputs are connected to the printed circuit board (9) with shielded cables on the front side of the housing (1) there is an outlet (17) for connecting an electromechanical valve, an outlet (18) for connecting a gas concentration sensor, with the outputs (17) and (18) connected by shielded multi-conductor cables to the printed circuit board (9), and from the pneumatic the block (2) to the front wall of the housing (1) removed the fitting (19) for supplying oxygen to the unit, the fitting (
