With the gradual increase in the prevalence of heart and lung diseases, oxygen generators have become a must-have for many patients at home. Nowadays, oxygen concentrator is a relatively common medical equipment in the family, which is suitable for the needs of most patients with respiratory diseases and some hypoxic patients. From the heavy oxygen cylinder in the past to the portable and safe oxygen concentrator, family oxygen therapy has also entered The new era.
1. For patients who need long-term home oxygen therapy, using an oxygen generator is one of the most convenient and economical options. At present, there are many kinds of oxygen generators on the market, and the general consumers are often dazzled when choosing and buying.
Today, we will combine some essential oxygen generator common sense to talk to you about how to choose a high-quality oxygen generator. One. Excellent oxygen generation capacity. The oxygen generation capacity of an oxygen generator directly determines this system. Whether the oxygen machine can bring enough oxygen to the user. According to the current regulations of the National Food and Drug Administration of China, the oxygen concentration of oxygen generators must be ≥84%. At present, most oxygen generators on the market have a nominal oxygen concentration of more than 90% in the publicity 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.
2. Molecular sieve type oxygen generator Molecular sieve is one of the core components of the oxygen generator.
Its main function is to adsorb nitrogen and separate oxygen. Open the molecular sieve tank of the oxygen generator and 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 in oxygen generators, one is called lithium-based zeolite and the other is called sodium-based zeolite.
3. Molecular sieve type oxygen generator Molecular sieve is one of the core components of the oxygen generator.
Its main function is to adsorb nitrogen and separate oxygen. Open the molecular sieve tank of the oxygen generator and 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 in oxygen generators, one is called lithium-based zeolite and the other is called sodium-based zeolite.
The two zeolites have their own characteristics. Let’s talk about sodium-based zeolite first. In comparison, sodium-based zeolite is better than lithium-based zeolite in the ability to adsorb nitrogen, and the price of raw materials is also more expensive. Base zeolite is stronger, especially in moisture resistance. In the beginning, many oxygen generators used sodium-based zeolite, and until today, most oxygen generators use lithium-based zeolite. Because of its excellent performance, the molecular sieve tank is smaller and the oxygen generator is more compact.
At the same time, there are some high-end oxygen generators that use lithium-based sodium-based molecular sieves. This is more powerful. The lithium-based zeolite and sodium-based zeolite are mixed in a certain ratio and then put into a sieve tank. In this way, it can not only ensure the oxygen production capacity, but also have strong adaptability.
4. “Complex” filter system
When it comes to filtering, everyone is familiar with it. The filtration system on the oxygen generator is also an important part of the entire equipment. First of all, the primary filter of any oxygen generator is a simple filter cotton, while high-end oxygen generators generally use polyurethane shaped cotton.
Conventional oxygen generators have only these two-stage filters, but high-end machines will also have more sophisticated filtering devices inside, such as inline filters, such as biomembrane filters. The inline filter generally appears between the compressor and the four-way valve (some are called solenoid valves or nitrogen exhaust valves), so it is also called the compressor inline filter. Its main function is to release the compressor to the four-way valve. The impact. The four-way valve is connected to the compressor, two molecular sieves, and the exhaust muffler. It is a very important core component. Once the four-way valve has a problem, it is likely to cause damage to other components. The protection of the filter can greatly reduce the probability of problems with the four-way valve. It has played a great role in prolonging the service life of the oxygen generator. And it is also one of the key factors that enable continuous operation of the oxygen generator
5. If the continuous oxygen supply time is an oxygen generator that is only used for health care, it is often small in size, and its heat dissipation function is relatively poor, and it cannot work for a long time. However, most of the medical oxygen generators 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 an oxygen generator that can supply oxygen for a long time, so as not to meet the treatment needs.
