With the continuous development of science and technology, as well as the continuous improvement of people's living standards, and the gradual enhancement of people's health needs, oxygen will gradually become an important means of family and community rehabilitation. At this time, a new type of medical equipment: home oxygen concentrator is constantly rising and occupying the consumer market with a rapid momentum. However, many patients and oxygen users do not know enough about oxygen, oxygen therapy is not standardized, so what people need oxygen, how to oxygen and other issues, is every patient and oxygen users must understand the knowledge.
? Home oxygen concentrator oxygen concentration - home oxygen concentrator working principle
Using molecular sieve physical adsorption and desorption technology. Oxygen generator filled with molecular sieve, in the pressurized air can be adsorbed nitrogen, the remaining unabsorbed oxygen is collected, after purification treatment that is high purity oxygen. The molecular sieve will discharge the adsorbed nitrogen back to the ambient air when it is depressurized, and it can adsorb nitrogen and produce oxygen when it is pressurized next time, the whole process is a cyclic dynamic cycle, and the molecular sieve is not consumed.
Home oxygen concentrator oxygen concentration - how much oxygen concentration is good
From the health care point of view, 30% is the best, to reach more than 90% of the concentration is not for the normal people, normal people in more than 90% of the concentration to stay for a few hours, there will be a situation of oxygen toxicity, such as tachycardia, etc., the oxygen concentration of the air is less than 21%, there will be chest tightness, etc., less than 21%, there will be a situation of chest tightness, etc., there will be a situation of chest tightness. There will be chest tightness and so on, below 17% will directly lead to brain hypoxia, to know that the brain is the whole human body oxygen consumption of the most organs (20% or so are supplied to the brain) the original study of the dangerous characteristics of oxygen had done a detailed investigation and research, and now just by memory. Oxygen concentrator is generally only 30% of the health care oxygen, generally using oxygen-rich membrane technology. Currently not through the medical device production license, can only be used as a health device, its principle is to use oxygen and nitrogen molecules in the oxygen-enriched membrane dissolution rate is different. It can realize the oxygen enrichment from the air and exclude the nitrogen. So as to obtain the required oxygen enrichment. It does not need additives or water. It can be used as an oxygen absorber when plugged into a power source.
Oxygen Concentration of Home Oxygen Concentrator - Test Method
1,? Open the oxygen concentrator power switch, the flow rate is located in the 3 liter position, the machine runs normally for more than 5 minutes.
2.? Take a transparent glass cup, pour 1cm? height of water, put the oxygen tube nose suction head in the glass cup, cover the mouth of the cup with a piece of paper.
3, 3 minutes later, remove the paper, gently remove the glass nasal suction head, then the glass is full of oxygen.
4.? Light a match or toothpick and blow out the open flame.
5.? Gently place the match with the spark into the glass slowly.
6.? The match re-burns, proving that it is oxygen.
7.? Typically, the higher the concentration of oxygen, the brighter the burning flame.
Through the above steps operation, basically can judge the oxygen concentration situation, if you find that the match can not be re-burned or the flame is weak, it means that the oxygen concentration is low, you should contact the manufacturer, for maintenance.
The above is about home oxygen concentrator oxygen concentration is how much more appropriate and how to determine the oxygen concentration of a simple introduction, I hope that through the introduction of the above to the majority of oxygen therapy consumers have some help. We are all aware of the role of oxygen therapy, it is not only able to relieve nerve fatigue, relaxation, maintain high energy, improve work efficiency; but also improve the brain oxygen supply, regulate the function of the cerebral nervous system, improve memory and thinking ability, improve learning efficiency;? At the same time reduce pollution and the harm to the body in a bad environment; thus the role of oxygen therapy is not to be underestimated. But we must also understand the correct concentration of oxygen.
