How to test the concentration of oxygen produced by the oxygen concentrator

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 absorption 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. Oxygen concentration of home oxygen concentrator - home oxygen concentrator working principle using molecular sieve physical adsorption and desorption technology. Oxygen concentrator filled with molecular sieve, in the pressurized air nitrogen adsorption, the remaining unabsorbed oxygen is collected, after purification process that becomes high purity oxygen. The molecular sieve will discharge the adsorbed nitrogen back to the ambient air when it is depressurized, and 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. Oxygen concentration of home oxygen concentrator - how much oxygen concentration is good from the health care point of view, 30% is the best, to reach a concentration of 90% or more is not for normal people, normal people stay in the concentration of more than 90% for a few hours, there will be oxygen toxicity, such as tachycardia, etc., the oxygen concentration of the air is less than 21%, there will be a tightness of the chest and so on, less than 17% will lead to a lack of oxygen in the brain directly, you know that the brain is the most oxygen-consuming organ of the whole human body, the brain is the most oxygen-consuming organ. It should be known that the brain is the most oxygen-consuming organ of the entire body (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. Just plug in the power supply and you can inhale oxygen.　　Oxygen concentration of home oxygen concentrator - test method 1, open the oxygen concentrator power switch, the flow is located in the position of 3 liters, the machine runs normally for more than 5 minutes.　　2, take a transparent glass cup, pour 1cm height of water, put the oxygen inhaler nose suction head in the glass cup, cover the mouth with a piece of paper.　　3、After 3 minutes, remove the paper, gently take out the nasal suction head in the glass cup, then the glass cup is full of oxygen.　　4, light a match or toothpick, blow out the open flame.　　5, gently put the match with sparks slowly into the glass.　　6. The match re-burns, proving that it is oxygen.　　7、Usually, the higher the concentration of oxygen, the brighter the burning flame.　　Through the operation of the above steps, basically can judge the oxygen concentration, if you find that the match can not be re-burned or the fire is weak, indicating that the oxygen concentration is low, you should contact the manufacturer, maintenance.
