According to the official website of the State Food and Drug Administration, oxygen generators are also called small molecular sieve oxygen generators, medical molecular sieve oxygen generators, household molecular sieve oxygen generators, and portable oxygen generators. Using air as the raw material, without any additives, turn on the power supply at room temperature, absorb ammonia and other gases through molecular sieves, and then separate the oxygen with a purity of 73 ± 3% from the air, according to the maximum oxygen flow rate per minute. It is 1L, 3L, 5L, 10L oxygen generator. The State Food and Drug Administration is in accordance with the management of second-class medical devices.

From a medical point of view, people with lung disease, cardiovascular disease, severe anemia and other diseases need to use oxygen concentrators. However, various places are gradually ushering in the peak of new crown virus infection. Do ordinary families need to be equipped with oxygen generators?

According to the "Beijing Daily" report on November 18, Li Tong, chief physician of the Department of Infectious Diseases, Beijing You'an Hospital Affiliated to Capital Medical University, once said that oxygen generators are mainly used by patients with chronic respiratory diseases, and generally healthy families do not need to configure them at home. Oxygen machine.

Li Tong once believed that if chest tightness, wheezing, dyspnea or other symptoms of hypoxemia occur, he should go to the hospital as soon as possible. It is not advisable to use an oxygen generator to inhale oxygen at home. It is easy to cause oxygen poisoning and cause danger.

In recent years, with the aging population and the COVID-19 epidemic increasing people's emphasis on lung function, the need for daily monitoring of lung function has become prominent, and oxygen generators have entered a stage of rapid development. According to a research report released by Guolian Securities on October 31, from 2014 to 2021, the output of oxygen generators in my country will increase from 197,600 units to 4.16 million units, with an average annual compound growth rate of 54.54%.

In terms of market size, my country's oxygen generator market is growing rapidly. According to the "2023-2028 China Oxygen Concentrator Industry Development Prospect Strategy and Investment Risk Forecast Analysis Report" released by Zhongyan Puhua Research Institute, the scale of my country's oxygen concentrator industry is about 4.05 billion yuan in 2019, and will increase to 5.586 billion yuan in 2020 . According to the development trend of the industry, by 2026, the market size of China's oxygen generator industry will reach 15.723 billion yuan.
