Oxygen concentrator ranking
Ranking 1, Invacare 2, Zhongjin 3, Kaya 4, Aisong 5, Kangshang 6, Turtle 7, Shenlu 8, Fishyue 9, easy source of oxygen
The best quality is the Invacare and Zhongjin, and the highest price-performance ratio of the number of Zhongjin oxygen concentrator
In recent years, the domestic Molecular sieve oxygen concentrator is becoming more and more popular and is becoming the main home oxygen therapy equipment. At present, China does not have a small molecular sieve oxygen concentrator industry standards with international standards.
The international standard ISO8359 and the U.S. standard F1464-93 have mandatory specifications for molecular sieve oxygen concentrators as follows:
● The product must be designed with an unalterable cumulative timing function.
● The product must be designed with an oxygen concentration monitoring system.
● The product must have an oxygen concentration change within ±3% of the rated flow rate under continuous operation, and the average oxygen flow rate fluctuation must be within ±10%.
● The oxygen concentration of the product in the whole process of use must not be lower than a certain safety value, the international standard is 82%, the U.S. standard is 85% (our country only on the new machine factory requirements, not the use of the process of the oxygen concentration of the safety value of the requirements).
● Regular maintenance to ensure the stability of the oxygen concentration and oxygen flow accuracy and other indicators.
At present, the domestic molecular sieve oxygen concentrator has many types, the quality is uneven, and the performance is very different. With reference to the above standards, consumers can consider the following three aspects to rationally choose the right molecular sieve oxygen concentrator.
