Abstract

Usage: in medical technology to normalize the function of the respiratory system, normalize the content of carbon dioxide. SUMMARY OF THE INVENTION: The device comprises a communicating breathing mask, an air duct, and an airtight container filled with carbon dioxide under pressure. The mask has two inspiratory valves and an adjustable exhalation valve. A gearbox is installed at the inlet of the duct, and the duct outlet is connected to the mask through an additional line. The line has a locking element installed with the possibility of blocking its passage section. The ratio of the flow cross sections of the line and the inspiratory valve is 7:93. 3 ill.

The invention relates to medical equipment and can be used to normalize carbon dioxide in the blood and, accordingly, to normalize the function of the respiratory system.

An object of the invention is to increase the physiological ™ performance of the device. This problem is solved in that in a device for normalizing the function of the respiratory system, comprising a breathing mask with an air duct and an airtight container filled with dioxide, an inspiratory valve and an exhalation valve; according to the invention, the respiratory mask is provided with two nozzles in which the inspiratory and expiratory valves are respectively located, the exhalation valve being adapted to regulate its passage section. the oven is communicated with the mask by means of an additionally introduced magmstral with a locking element installed with the possibility of blocking the latter.

This embodiment of the device allows the supply of carbon dioxide in a mixture with air in the required ratios, excluding the excess of the concentration of carbon dioxide above the permissible levels, to regulate the exhalation resistance, which will increase the physiological effect of the device.

carbon monoxide and equipped with a reducer 4.

Air duct 2 is in communication with the breathing mask 1 by an additionally introduced line 5 with a spring-loaded locking element 6 pivotally connected to the piston 7. installed with the possibility of blocking the line 5.

The respiratory mask 1 is equipped with two nozzles 8.9, in which the inspiratory valves 10 and exhale 11 are respectively placed. The exhalation valve 11 in the nozzle 9 is equipped with a rotary disk 12 and a fixed disk 13 with identical holes 14.15. In the pipe 8, the holes 18 are closed valves 10 and 3 of elastic material, opening upon inhalation and closing upon exhalation. In the pipe 9, the openings 15 are closed by valves opening on the exhale and closing by inspiration.

A device for normalizing the function of the respiratory system operates as follows. Using a reducer 4, the flow rate of carbon dioxide is determined depending on the pressure in the sealed container 3 so. so that the ratio of carbon dioxide is 3-7% and 97-93% of the inhaled air through the holes 16 of the pipe 8.

The concentration of carbon dioxide under the breathing mask is preliminarily checked by a gas analyzer. The respiratory mask 1 is put on the patient’s face and briefly pressed on the spring-loaded locking element 6, which, acting on the piston 7, opens the line 5 and a portion of carbon dioxide mixed with air from the pipe 8 enters the patient’s airways through the respiratory mask 1. When inhaling through the holes 16 the nozzle 8 opens the valve 10, and when the exhalation of the valve 10 is closed, but at this time the valves 11 are opened in the holes 15, the nozzle 9;

By rotating the disk 12, the flow area between the holes 14, 15 is reduced, gradually increasing the exhalation resistance or the optimal exhalation resistance is established.

for r mul a. A device for normalizing the function of the respiratory system, comprising a communicating breathing mask, an air duct and an airtight container for filling with two carbon monoxide, inspiratory and expiratory valves, characterized in that, in order to prevent large the concentration of carbon dioxide and regulating the exhalation resistance, the mask is equipped with two nozzles in which the inspiratory and expiratory valves are respectively located, the exhalation valve being configured to regulate its passage, cross-section, etc. This inlet duct is further mounted gearbox, and an output duct coupled to the mask through the additionally introduced main line with a locking element mounted to overlap its passage sectional area sootnshenie and whose passage area is equal to the inhalation valve sectional 7:93.
