In recent years, with the development of society, due to the improvement of living standards, air pollution has become more and more serious. People suffering from cardiovascular and cerebrovascular diseases, coronary heart disease, cerebral thrombosis, hypertension, pneumonia, bronchitis, asthma, or pulmonary heart disease. Increasing. Although these patients can be basically controlled after treatment, they need long-term oxygen therapy to ensure their quality of life due to chronic respiratory insufficiency. Due to various reasons, many people cannot often go to the hospital for oxygen therapy, or to save costs and avoid nosocomial infections, they often choose to perform oxygen therapy at home.

Home oxygen therapy has brought good news to patients with chronic obstructive pulmonary disease or pulmonary heart disease who need long-term oxygen therapy, but it also brings problems. Because there are many types and brands of oxygen concentrators in the market, many people do not know how to choose a home therapeutic oxygen concentrator.

Today, let’s learn together how to choose a household oxygen generator.

Choosing a therapeutic home oxygen generator

If you want to treat diseases, you can't choose ordinary oxygen concentrators, because the oxygen concentration of ordinary oxygen concentrators cannot achieve the effect of curing diseases. It is recommended that patients who need long-term oxygen therapy choose a therapeutic medical-grade oxygen generator, so that the therapeutic effect can be guaranteed and the physical condition can be improved. The oxygen generators in the market that can achieve therapeutic effects are all above 5L.

The principle of oxygen generator

At present, there are three types of household therapeutic medical-grade oxygen generators in the market: electronic oxygen generators, chemical oxygen generators and molecular sieve oxygen generators. Before purchasing a household oxygen generator, we must first understand the oxygen generation principles of several oxygen generators.

1. Electronic oxygen generator: The electronic oxygen generator uses the process of oxidizing and reducing the oxygen in the air in a solution to release oxygen. Although the oxygen generator of this process has the characteristic of large oxygen supply per unit time, such products have very high requirements for air purification, and the oxygen purity is difficult to meet the requirements of medical oxygen. Moreover, the product cannot be tilted or turned upside down during use, otherwise it will cause more serious consequences.

2. Chemical oxygen generator: The chemical oxygen generator relies on adding an oxygen generator such as sodium peroxide to the water to produce oxygen under the action of a catalyst. This oxygen production method is not only troublesome, but also expensive to use.

3. Molecular sieve oxygen generator: molecular sieve oxygen generator uses a relatively advanced molecular sieve pressure swing adsorption (PSA) process, which has a high oxygen concentration in the oxygen generator, and molecular sieve oxygen generator is currently the only mature Yes, an oxygen generator with international and national standards.

Precautions for purchasing oxygen generator

(1) Pay attention to the oxygen concentration

When we purchase an oxygen generator, we must pay attention to the stable oxygen concentration of the oxygen generator. This is a key factor in distinguishing the quality of an oxygen generator. According to the (China) State Food and Drug Administration's specifications for oxygen generator products, the oxygen concentration of oxygen generators must be maintained at more than 90% in order to be considered a qualified product.

(2) Pay attention to the stability of the oxygen generator

When many oxygen generators are first purchased, the oxygen concentration is relatively stable and can reach more than 90%. However, after a period of use, the oxygen concentration will decrease. In some oxygen generators, the oxygen concentration is higher in the first few hours of use, but the oxygen concentration will decrease in the later hours. For patients with chronic obstructive pulmonary disease, they have to inhale oxygen for a long time every day, and the treatment effect will be compromised if the oxygen generator with unstable oxygen concentration is used.

(3) Pay attention to accurate flow

In addition, when purchasing an oxygen generator, you also need to pay attention to the precise flow rate of the oxygen generator to ensure that the output value of the oxygen generator is accurate, and there should be no deviation, otherwise it will affect the use effect.

(4) Pay attention to noise

Some oxygen generators have relatively loud noises, resulting in poor experience during oxygen inhalation. Choosing a low-noise oxygen concentrator can improve the user's sense of experience, thereby helping users to adhere to long-term oxygen therapy and promoting physical health.

(5) Choose a big brand with good technology and good after-sales

When purchasing an oxygen generator, you should also choose products that meet internal technology standards. For example, as mentioned above, molecular sieve oxygen generators are more popular nowadays. When purchasing this type of oxygen generator, you must choose a brand of oxygen generator with good technology and quality assurance. Because brand protection is not only related to product quality, but also related to after-sales service, so we must choose a trusted brand with a good reputation.

(6) See if there is medical device certification

   Regardless of whether it is a household-grade or medical-grade oxygen generator, a medical device qualification certificate is required. When purchasing a product, you must look at the certificate.

In the current market, the therapeutic medical-grade molecular sieve oxygen generators worth choosing include brands such as Yuyue, Meizhioxy, Keer, Daikin, and Besure. In order to help everyone more easily choose their own oxygen generator, Here we compare the oxygen production system, oxygen output flow, flow adjustment, timing/countdown, alarm, and negative ions of several 5L therapeutic medical-grade oxygen generators of similar brands:

Among them, Besure 5/5E/5K products are more eye-catching in all aspects, have medical device certification, use air as raw material, use molecular sieve pressure swing adsorption process, and produce oxygen-enriched air by adsorbing nitrogen and other gases, with an oxygen concentration of 93±3%. It is suitable for oxygen therapy or to relieve the discomfort caused by hypoxia.

In addition, it adopts modular molecular sieve bottom design, domestic top air compressor, condensate drainage design, 0.1L visualization can only be adjusted, multi-level silencer, meticulous detail design, multi-level intelligent warning, etc. The oxygen concentration is as high as 93%, after-sales service Better protection. It is a household oxygen concentrator product that is very worth starting.
