With the gradual increase in the prevalence of heart and lung diseases, oxygen concentrators have become a must-have for many patients at home. Nowadays, oxygen concentrators, as a relatively common medical equipment in the family, are suitable for the needs of most respiratory diseases and some hypoxic patients. From the heavy oxygen bottles in the past to the lightweight and safe oxygen concentrators, family oxygen therapy has also entered new era.

For patients who need long-term home oxygen therapy, the use of oxygen concentrators is one of the most convenient and economical options. At present, there are various types of oxygen concentrators on the market, and the general consumers are often dazzled when they choose to buy. Today we will combine some essential oxygen concentrators common sense to talk to you about how to buy a high-quality oxygen concentrators

1. The oxygen production capacity of an oxygen concentrators directly determines whether the oxygen concentrator can bring enough oxygen to the user. The oxygen concentration of oxygen production equipment must be ≥84%. At present, most oxygen concentrators on the market have a nominal oxygen concentration of more than 90% in the publicity instructions. Here we all must pay attention to that there will be partial oxygen concentrators, and 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.

2. Molecular sieve type oxygen concentrators Molecular sieve is one of the core components of the oxygen generator. Its main function is to adsorb nitrogen and separate oxygen. Opening the molecular sieve tank of oxygen concentrators, we will find that the internal medium is rice-sized stones, which we call "zeolite". There are also many types of zeolite, two of which are generally used on oxygen concentrators, one is called lithium-based zeolite and the other is called sodium-based zeolite. At the same time, there are some high-quality oxygen concentrators, which use lithium-based sodium-based mixed molecular sieves. This is more powerful. The lithium-based zeolite and sodium-based zeolite are mixed in a certain ratio and then put into the sieve tank. It can not only ensure the oxygen production capacity, but also have strong adaptability.

3. Complex" filtration system, when it comes to filtration, everyone is familiar with it. The filtration system on oxygen concentrators is also a very important part of the entire equipment. First of all, the primary filtration of any oxygen concentrators is a simple filter cotton. High-end oxygen generators generally use polyurethane shaped cotton.

4. Continuous oxygen supply time, if it is oxygen concentrators only used for health care, they are often small in size, and the heat dissipation function is relatively poor, and they cannot work for a long time. However, most of the medical oxygen concentrators used for treatment can work uninterrupted 24 hours a day. For patients with chronic obstructive pulmonary disease and chronic respiratory failure, they need no less than 15 hours of oxygen inhalation time a day, so you need to choose to buy oxygen concentrators that can supply oxygen for a long time, so as not to meet the treatment needs.

At the same time, the prices of oxygen concentrators vary. We don’t recommend buying household oxygen concentrators blindly looking for low prices, ignoring the value and after-sales service of oxygen concentrators. After all, oxygen generators are not consumer products, so don’t blindly believe in high-quality prices. inexpensive. Well, after learning the above points, I believe it will provide a lot of help for everyone when buying oxygen concentrators.
