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 generators in the market, many people don’t know how to choose a household treatment type oxygen generator.
Choosing a therapeutic home oxygen generator
If you want to treat diseases, you cannot choose an ordinary oxygen generator machine, because the oxygen concentration of an ordinary oxygen generator machine cannot achieve the effect of curing diseases. It is recommended that patients who need long-term oxygen therapy choose a therapeutic medical oxygen generator so that the therapeutic effect can be guaranteed and the physical condition can be improved. Oxygen concentrators that can achieve therapeutic effects in the market are all above 5L.
The principle of oxygen concentrator
At present, there are three types of home therapeutic medical oxygen generators in the market: electronic oxygen generators, chemical oxygen concentrators, 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 concentrator uses the process of oxidizing and reducing the oxygen in the air in a solution to precipitate oxygen. Although the oxygen generator of this process has the characteristic of a large oxygen supply per unit of 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 the molecular sieve oxygen generator is currently the only mature Yes, an oxygen generator with international standards.
At present, most of the oxygen generators on the market have a nominal oxygen concentration of more than 90% in the promotional instructions. All of us must pay attention here, there will be partial oxygen generators, the nominal oxygen concentration of 90% is the flow rate of 1L/min. As the flow rate increases, the oxygen concentration drops immediately. Be sure to pay attention to this before buying.
