Description

one

The invention relates to insulating breathing apparatus, which allows for artificial ventilation of the lungs when the victim is in a respirator protective mask during accidents in mines, chemical plants, etc.

Well-known regenerative respirators containing a half-mask with a mouthpiece, breathing hose with inhalation and exhalation valves, a balloon with compressed oxygen, a regenerative cartridge, a breathing bag with an excess valve, and an automatic breathing apparatus attached to the bag with automatic equipment that switches it from inspiration mode to expiration and back , provide artificial respiration and first aid to victims when they are in a respirator protective mask.

However, the heavy weight and bulkiness of such special respirators cause known difficulties in their use during rescue operations.

The purpose of the present invention is to reduce the weight and size of insulating respirators, allowing for artificial ventilation of the lungs when the victim is in a protective mask.

This goal is achieved by the fact that in an insulating respirator on the air ducts between the regenerative cartridge and the inhalation hose

A breathing bag is installed, combined with a device for controlling the volume of breathing air injected into the human lungs. Such a bag arrangement allows artificial respiration to provide first aid to victims in the environment of harmful gases.

SUMMARY OF THE INVENTION

FIG. 1 shows a schematic of an insulating respirator; in fig. 2 - breathing bag with a device for volume control.

Isolating respirator contains a balloon / compressed oxygen, oxygen supply

block 2, regenerative cartridge 3, exhalation valves 4 and inhalation 5, intake hose 6 and expiration 7, half mask with mouthpiece 8, breathing bag 9 with excess valve m 10 and plates mounted on it outside //

and 12 and clamps / 5 and J4 with clamps 15 and 16.

When carrying out artificial ventilation of the lungs, the respirator works as follows.

The breathing bag 9 is filled with oxygen from the balloon 1, when the bag 9 is pressed between the plates 11 and 12, the exhalation valve 4 is closed and the oxygen from the bag through the ducts 17 and 18 through the inhale valve 5 and

the inhale hose 6 enters the human lungs.

3

After the bag is pressed out of compression I, the valve 5 is closed and the gas from the human lung through the hose 7 through the valve 4 passes into the regenerative cartridge 3, is cleaned of carbon dioxide and enters the bag 9. The oxygen consumption in the respiratory respiratory system is replenished by continuously supplying it from the cylinder 1 through the oxygen supply unit 2. After a full expiration and filling of bag 9, the breathing cycle is repeated. The volume of ventilation of the lungs can be adjusted by changing the size of the bag 9 with the help of clips 13 and 14, bending the edge of the bag and fitting them in this position with the latches -15 and 16.

Subject invention

An insulating respirator containing a half-mask with a mouthpiece, breathing hoses with inhalation and exhalation valves, regenerative cartridge, characterized in that, in order to provide artificial ventilation of the lungs while the victim is wearing a respirator protection mask, there is a breathing bag at the exit of the regenerative cartridge. in the form of an elastic container, bounded on the outside by two plates and at opposite corners by two clamps with clamps for changing the volume.
