As air pollution continues to increase, and the number of patients with lung diseases continues to increase. Oxygen concentrators are increasingly becoming a hot-selling medical device. Whether it is health care oxygen inhalation or home oxygen therapy, there is a great demand for oxygen concentrators.
Although the sales volume is increasing and the frequency of use is increasing, most people do not understand the “truth” of the oxygen concentrator. There are different perceptions about whether it is producing oxygen or filtering oxygen. Many people think that the oxygen concentrator focuses on the filtration system in the promotion, so the oxygen concentrator filters the oxygen in the air for patients to inhale oxygen.
But what are the facts? Perhaps understanding the working principle of the oxygen generator can reveal the answer.
The oxygen generator uses the characteristic of different condensation points of different components in the air to separate the air from gas and liquid, and obtain oxygen through further distillation. Among them, molecular sieve is the core component of the oxygen generator, and it is also the key step of the oxygen generator. The oxygen generator makes full use of the physical adsorption performance of molecular sieves, and uses oil-free compressors as power to separate nitrogen and oxygen in the air. The final result is high-concentration oxygen. As for the filtration system that is mistaken for the oxygen generator to filter oxygen, it is the pre-step of the oxygen generator. It can ensure that the air entering the molecular sieve is clean enough, and the final output oxygen concentration and safety are better guaranteed.
While outputting high-concentration oxygen, the molecular sieve will discharge the adsorbed nitrogen into the air during decompression, and the next pressurization will re-adsorb the nitrogen to produce oxygen. In this oxygen production cycle, the molecular sieve will not be consumed.
However, it should be noted that although the core component of molecular sieve is not consumed naturally, the performance of oxygen generators of different qualities after working for a long time is significantly different. The most intuitive manifestation is that the oxygen concentration will attenuate, which directly leads to poor oxygen inhalation effects and even harms the health of patients.
Therefore, in the choice of oxygen concentrator, users should choose a suitable oxygen concentrator according to their own needs. For non-therapeutic consumers, a small-capacity oxygen generator can achieve results. But for patients suffering from chronic obstructive pulmonary disease or similar serious diseases, only by choosing a medical-grade oxygen generator can they benefit from home oxygen therapy, not just a kind of psychological comfort.
Taking COPD patients as an example, the reason why we need to use medical-grade oxygen concentrators is because from the perspective of treatment effects, COPD patients must receive oxygen therapy at home for more than 15 hours a day and continuous oxygen for 500 days , Can obtain obvious oxygen therapy effect. Therefore, in the choice of oxygen concentrator, it is necessary to pay attention to the two points of oxygen concentration and continuous working performance. Only when the time requirement of oxygen therapy can be met can the expected effect of home oxygen therapy be exerted.
With the increasing acceptance of the concept of home oxygen therapy, it is believed that the oxygen generator market will remain hot in the future. For patients who need to rely on home oxygen therapy to save lives and improve their quality of life, the right choice needs to be made.
