Home oxygen concentrator is a lightweight oxygen generator for home use, and its oxygen generating principle generally has molecular sieve principle, polymer oxygen-rich membrane principle, electrolytic water principle and chemical reaction oxygen generating principle, and molecular sieve oxygen generator is the only mature oxygen generator with international and national standards.
One, the working principle of home oxygen generator - molecular sieve
Home oxygen generator working principle: the use of molecular sieve physical adsorption and desorption technology. Oxygen generator 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 in the decompression of the adsorbed nitrogen will be discharged back to the ambient air, in the next pressurization can be adsorbed nitrogen and oxygen production, the whole process for the cyclical dynamic cycle, the molecular sieve is not consumed.
Two, the purchase of home oxygen concentrator
Oxygen concentrator output must be greater than 90% of the oxygen concentration, you can use the instrument or the machine comes with the oxygen monitoring device to detect. You should choose an oxygen concentrator with an unchangeable cumulative timer function in order to provide objective and accurate data for future long-term maintenance and repair and service. Equipped with a cumulative timer is a mandatory requirement of international standards and a reflection of the quality of the product. The service life of the oxygen concentrator (oxygen machine) should be able to guarantee tens of thousands of hours. To choose the oxygen concentrator (oxygen machine) with low noise, the noise level should preferably be less than 45 decibels, otherwise, it may affect the rest of myself and others, especially at night. In addition, should also pay attention to the following matters:
1, home oxygen generator generally use molecular sieve oxygen principle, so the molecular sieve adsorption performance and service life is very important, and its installation process is also very critical, when you buy should choose the metal integration structure, and with the molecular sieve automatic early warning of loading oxygen generator.
2, for respiratory, cardiovascular disease patients on the home oxygen concentrator performance requirements of higher call, when buying should choose to be able to Avenue standard medical indicators, long time continuous oxygen supply standard machine.
3, home oxygen concentrator is a medical device, not health fashion products, so there is no need to choose the appearance of fancy not applicable deformity, but the structure of excellent performance, compact size, and ideal heat dissipation machine.
4, with the ISO international and CE European quality system certification of the oxygen concentrator is an important guarantee of purchase, in addition to the time of the product on the market is also very important, it is best to choose more than two years after the introduction of the machine.
5, the purchase of oxygen concentrator to choose a long history, the strength of the oxygen concentrator / oxygen machine manufacturers, home oxygen concentrator after-sales maintenance and parts replacement is very important, only the long brand manufacturers to ensure sustainable development and maintenance services in the future.
6, according to the FDA's relevant research, the general user needs the amount of oxygen equivalent to 90% of the concentration of 3 liters per minute, it is recommended that the user to choose a large-flow machine.
7, the remote control is not a necessary function, this feature in the medical risk, the oxygen absorption rate of wheat is actually very low, almost negligible.
8, with cumulative timing function. It can count the service life of the oxygen machine, in order to provide objective and accurate data for future long-term maintenance and repair and service. International standards require that the oxygen generator is equipped with a cumulative timer, which is also a reflection of the quality of the product, the service life of a good oxygen generator should be able to guarantee tens of thousands of hours.
