Cylinders, for example, are shown in the variant of two cylinders - an inert gas and oxygen, but there can be three or more cylinders.

Implementation of the utility model.

Mobile apparatus for inhalation therapy with mixtures of inert gases with oxygen operates as follows.

Example 1. Without the use of electronic devices.

Through the filling device 2 under high pressure, inert gas is pumped into each of the cylinders 1, which is necessary to obtain a gas mixture. The high pressure sensor 4 indicates the residual pressure in the cylinder 1. The device for reducing gas pressure in the cylinder (reducer) 3 reduces the high pressure in the cylinder 1 to the working pressure in the breathing circuit. The manual regulator of the gas mass flow rate in the cylinder 5 ensures that the gas mixture is supplied to the breathing circuit in the required volume and flow rate. To carry out inhalation, it is necessary to connect the breathing circuit to each single replaceable block 25 through a quick-release pneumatic connection 6, and press the breathing mask 9 tightly against the nasal part of the face. To supply the gas mixture to the breathing circuit, it is enough to turn the handle of the mass flow regulator clockwise to the flow rate indicator on the body of the device to reduce the gas pressure in the cylinder. The respiratory circuit consists of connecting tubes 22, a filter 8, a safety valve 11, a breathing bag 10, a breathing mask 9, an inhalation valve 12, an exhalation valve 13, a moisture separator and a CO ₂ separator (14). By means of a mass flow regulator, the medical specialist ensures easy and free breathing of the patient in the concentration required for him.

Example 2. With electronic devices.

When the device is connected to the network, the control unit 20 tests the correct operation of the system and displays the date, time, pressure and amount of gas in the cylinders on the screen 21. Rotation angle sensors or the corresponding keyboard sets the volumetric flow rate of the working mixture and the percentage concentration of oxygen and xenon in the mixture. The set values of the volumetric flow rate and concentration of gases in the mixture are visually displayed using a matrix indicator on the information screen 21, this allows you to control the set parameters of the working gas mixture before starting the inhalation procedure. During operation, the microcontroller of the gas mass flow controller 5, based on the values of the specified total volumetric flow rate of the mixture and the required concentrations of oxygen and xenon, automatically calculates the required volumetric flow rates (in l/min) for each of the gas components; this information is also displayed on the matrix display of the information screen 21.

When applying, using the control keyboard, a signal to start the inhalation mode, the control unit captures, displays and stores in memory the parameters and all modes of the procedure. During the operation of the device, the control unit analyzes the pressure values in the cylinders according to the readings of pressure sensors 4 and, if the measured pressure values are within the established limits (4-5 bar), further operation of the device occurs with flashing parameters on the screen, and at a pressure of 4 bar and below, information is displayed about the impossibility of the device operation and the need to fill the corresponding gas into the cylinder. In this case, the control unit stops the supply of mixture to the breathing circuit. At pressures below 3 bar, the cylinder depressurizer 3 does not allow gas from the cylinder to enter the breathing circuit.

In addition, if in the process of adjusting the required flow rates (for any component - oxygen or xenon) it is not possible to obtain, the microcontroller of the control unit turns off the electrically controlled gas mass flow regulators 5, closing the gas supply to the gas line, and displays information on the matrix display about the impossibility of obtaining gas mixture of the required volumetric flow rate or concentration, indicating which of the parameters did not reach the required value. The use of oxygen sensor 15, installed directly in the breathing bag, eliminates the occurrence of situations when, for any reason, the oxygen content in the gas mixture becomes below the minimum possible level; in this case, the microcontroller of the control unit will also automatically turn off the gas mass flow controllers 5, excluding further supply of the gas mixture, and will display on the matrix display the relevant information about the reasons for interrupting the inhalation procedure. The inhalation procedure can be stopped or interrupted by a command received from the control keyboard; in this case, the matrix display will display information on the total time of the inhalation process, the volume (in liters) of oxygen and xenon received by the patient during inhalation, as well as the average percentage of carbon dioxide in the gaseous medium exhaled by the patient for the entire inhalation cycle.

The microcontroller of the control unit provides the following modes of inhalation:

- by the time when the microcontroller turns off the gas mass flow regulators 5 after the specified time of the patient's inhalation mode (for example, 10 s, 20 s, etc., but not more than 5 minutes),

- upon receipt by the patient of a given volume of xenon in the gas mixture - the specified operating modes of the device are set immediately before the start of the inhalation mode and can be selected for each patient individually;

The use of mass flowmeters in this device for obtaining gas mixtures with the required concentration of oxygen and xenon makes it possible to abandon the use of an expensive and difficult to operate, requiring constant qualified maintenance, gas analyzer.

The mass flow meters used in the device make it possible to measure the concentration of oxygen and xenon in the working mixture with high accuracy, without requiring their calibration before starting the inhalation procedure, while using the known standard gas parameters obtained for normal conditions.

The proposed scheme of the device allows you to set the desired mode of operation before the start of the patient's inhalation procedure, without requiring the attendants to continuously adjust the volumetric flow rates of oxygen and xenon directly during the inhalation procedure to obtain the required ratios of the gas components, which is extremely difficult when the pressure at the outlet of the gas cylinders changes over time. by changing the volume of gas in them during inhalation.

The use in the device of pressure sensors in the oxygen and xenon supply channels, as well as an oxygen sensor installed at the outlet of the breathing bag, makes it possible to eliminate the occurrence of emergencies associated with a small amount of gas in high-pressure cylinders, as well as in cases where the oxygen content in the gas the mixture will fall below the minimum allowable, according to medical requirements, level.

The use of a safety valve in the device makes it possible to exclude an increase in pressure in the breathing circuit above the working one. The carbon dioxide concentration sensor controls the process of purification of the gas mixture during the entire xenon therapy procedure.

The control unit connects a computer, tablet or phone to it using a wireless communication system, which allows you to control the device remotely and meet modern telemedicine requirements.
