How to use zyx45 isolated compressed oxygen self-rescuer oxygen analyzer?

Turn the oxygen cylinder switch 14 counterclockwise, and the hyperbaric oxygen will flow from the oxygen cylinder 12 to the pressure reducing valve 13. After decompression, oxygen of 1.2 L/min will be automatically output to enter airbag group 4. Press the air supply pressure plate with your fingers, and oxygen enters the airbag 4 at a speed of 60 L/min. Leave the air supply pressure plate 3 by hand, and the oxygen supply will stop.

This product also has the function of automatic oxygen supply. When the respiratory system is under negative pressure, the air supply pressure plate 3 contracts inward, pressing the air supply rod (in the airbag) to open the oxygen supply mechanism, and the airbag is filled with oxygen at a speed of 60L/min. When the airbag inflates, the air supply pressure plate 3 leaves the air supply rod and the air supply stops. If the air pressure in the respiratory system exceeds a certain value, the gas will overflow from the exhaust valve.

When inhaling, oxygen enters the human body from the airbag 4 and the inhalation valve 2. When exhaling, the gas passes through the breathing valve 2, and the exhalation hose in the airbag enters the cleaning tank 7. CO2 exhaled by the human body is absorbed by the absorbent contained in the cleaning tank 7, and the remaining oxygen enters the airbag. Repeat this way to complete the human respiratory cycle. The human body's breathing is completely isolated from the outside atmosphere.
