Oxygen inhalation machine is a household product. With the continuous improvement of living standards, people pay more attention to health, and many families will buy oxygen machines. When using domestic oxygen inhalers, we must also pay attention to many problems, such as whether patients need low-concentration oxygen or high-concentration oxygen, and clearly judge that there will be no reaction after oxygen inhalation.
Using zeolite molecular sieve as adsorbent, oxygen in the air is separated from nitrogen by physical pressure swing adsorption, and harmful substances in the air are filtered out, thus obtaining high-purity oxygen that meets the medical oxygen standard.
If you don't feel comfortable with the home oxygen inhalation machine, you can go to a regular medical equipment store to buy oxygen cylinders, and the effect is similar to that of the home oxygen inhalation machine. In addition, in addition to giving oxygen to the elderly, the family had better help the elderly to go for a walk in a better air. It will be much better to absorb such fresh air than oxygen.
Working principle of oxygen inhalation machine
Chemical oxygen inhalers have developed rapidly in China in recent years because of their simple structure and convenient operation. Physical oxygen production does not need chemicals, and takes air as raw material, which is an ideal oxygen supply method. Foreign countries have developed rapidly, mainly using membrane separation and pressure swing adsorption processes, that is, molecular sieve oxygen absorber.
Oxygen supply by oxygen cylinders, oxygen bags, oxygen cylinders and oxygen bags is an extension of traditional low-temperature oxygen production methods. The cryogenic method uses air as raw material, and oxygen and nitrogen are separated by distillation, so that the produced oxygen has high purity. When in use, the oxygen is delivered to the hospital through the high-pressure gas cylinder, and the oxygen is decompressed and limited through mixed-flow discharge or pressure reducer, and then is inhaled by patients after passing through the humidification bottle. The oxygen bag is used with the oxygen cylinder, which is convenient to carry, not limited to the accessories of the oxygen cylinder, and expands the oxygen absorption area.
