M9 oxygen tank are ideal oxygen supply devices for hospitals, first aid stations, nursing homes, home care, outdoor rescue, personal health care and oxygen supplementation in a variety of hypoxic environments.
After the medical oxygen is filled, each cylinder shall be leak-checked, and the nozzle and valve shall be protected, and the bottle cap and shock-proof ring shall be put on. And production, storage, transportation, sales should conform to the provisions of the relevant departments, and obtain the relevant certificates.
The caution of using the medical oxygen:
Control oxygen concentration
The body's metabolism is inextricably linked to oxygen, and lack of oxygen is harmful to the body. Severe hypoxia can be life-threatening. However, if normal people inhale pure oxygen for a long time, it is not good for human body, but may cause oxygen poisoning. In order to avoid oxygen poisoning, oxygen concentration of less than 60% and oxygen partial pressure of less than 60KPa should be applied to adults during prolonged isobaric oxygen therapy. 450mmHg) of gas mixture; The oxygen concentration of the gas mixture used for newborn or nursing infants should not exceed 60% and the oxygen partial pressure should not exceed 40KPa (≤300mmHg).
