How Chemical Oxygen Self Rescuer Works

When using Chemical Oxygen Self Rescuer, turn the cylinder valve counterclockwise. The high pressure oxygen is decompressed from the oxygen cylinder through the pressure reducing valve, enter the airbag at ≥1.2L/min, and the hand is removed from the air pressure plate to stop. When the respiratory system is under negative pressure, the supplemental air pressure plate is inwardly contracted, and the air supply rod is pressed to open the air supply mechanism. The oxygen is filled into the airbag at ≥60L/min. When the airbag is bulged, the air pressure plate leaves the air supply rod and qi stop. If the air pressure in the breathing system exceeds the exhaust valve exhaust pressure, the gas will overflow from the exhaust valve. When inhaling, the oxygen in the balloon enters the body through the mouthpiece. When exhaling, the gas enters the clean tank through the exhalation hose. The carbon dioxide in the Chemical Oxygen Self Rescuer is absorbed by the CO2 absorbent placed in the clean tank, and the remaining gas enters the airbag and is compressed into a breathing cycle.
