The working principle of compressed oxygen self-rescuer
2022-07-20
●Quantitative oxygen supply: turn the switch hand wheel counterclockwise, high pressure oxygen flows from the oxygen cylinder to the pressure reducer, and automatically outputs 1.2L/min of oxygen into the air bag after pressure reduction.
●Manual air supply and oxygen supply: Press the air supply plate with your finger, oxygen enters the air bag at 60L/min, and the finger leaves the air supply plate, and the oxygen supply stops.
●Automatic air supply and oxygen supply: When the respiratory system is under negative pressure, the air supplementation plate contracts inwards, pressing the air supply rod to open the oxygen supply mechanism, and oxygen enters the air bag at 60L/min. When the air bag is rapidly inflated, the air supplementation plate leaves the air supply Gas lever, stop gas supply.
When inhaling, oxygen enters the human body from the air bag, breathing valve, and mouthpiece. When exhaling, the gas enters the purification tank through the breathing valve and the exhalation hose. The CO2 exhaled by the human body is absorbed by the absorbent contained in the purification tank, and the remaining oxygen enters the air bag and mixes with the oxygen output from the pressure reducer. This is repeated to complete the human breathing cycle.
