How to choose an oxygen generator?

Oxygen therapy is actually an important method to prevent or treat hypoxia outside the hospital, but not everyone is suitable for long-term oxygen therapy, nor is it that the more oxygen inhaled, the better.

For healthy people, high-flow oxygen inhalation without following the doctor’s advice may cause “oxygen poisoning”. For patients with chronic obstructive pulmonary disease, asthma, bronchitis and other diseases, long-term oxygen therapy can help delay the development of the disease and improve Exercise endurance and quality of life can also effectively improve the survival rate of COPD patients.

3L oxygen generator and 5L oxygen generator

The oxygen generators currently on the market are mainly divided into three types: 1 liter, 3 liters, and 5 liters according to how many liters of oxygen can be produced per minute. The 1 liter machine is mainly used for health care oxygen inhalation for people with mild hypoxia. The 3 liter and 5 liter machines are the most common and have the most types. They are mainly used for medical assistance for patients with respiratory diseases and lung diseases. Many major brands of oxygen concentrators are also mainly concentrated In these two categories.

Moderate and mild hypoxia patients use a 3L machine, and patients who need long-term oxygen therapy are more recommended to use a 5L machine. The reasons are as follows:

1. Machine life. The power components of the 5L machine are generally stronger than that of the 3L machine and can withstand higher workloads. Long-term high-flow operation of 3 liters will cause overload and shorten the life of the machine or even malfunction.

2. The disease progresses. Many chronic lung diseases (such as chronic obstructive pulmonary disease) are developmental and irreversible. As time goes by, the condition will only get worse. It is actually the most economical choice to buy a 5-liter machine from the beginning!

3. The difference in oxygen concentration. Taking the oxygen concentration required by patients with COPD (inhaled alveolar oxygen concentration) 29%-35% as an example, the oxygen concentration level of a 3L machine is about 28.39%, which can meet general medical needs, but it is difficult to meet the needs of patients who need long-term oxygen therapy. demand. The oxygen concentration level of the 5L machine is about 33.39%, which can effectively alleviate the patient’s condition.

From the perspective of the use of oxygen generators at home and abroad, compared with the large number of 3L machines used in China, users in European and American countries generally use 5L machines. Well-known foreign oxygen generator brands such as Asia and Philips also mainly produce 5L machines.

Under the condition that the oxygen concentration is up to 95% and the maximum flow is 5 liters, the battery life is up to 11.5 hours and the weight is only 2.3 kg. It is one of the few portable oxygen concentrators on the market.

The birth of the portable 5L oxygen generator is inseparable from the health of patients. Because many scientific studies have proved that proper exercise can effectively improve the survival rate of patients with lung diseases such as chronic obstructive pulmonary disease. The portable oxygen generator is more convenient for patients to carry out activities.

Although the portable 5L oxygen concentrator has many advantages, it has high production technology requirements for manufacturers and higher production costs, so the current market is still dominated by the larger desktop 5L oxygen concentrator.

In short, everyone chooses oxygen concentrators with different flow rates according to the actual situation, follow the doctor’s advice for oxygen therapy, and try to choose big-brand oxygen concentrators, so that you can use it with peace of mind and peace of mind.

The oxygen-enriched membrane is based on the principle of selective permeation of organic polymer membranes. It uses the characteristic of oxygen-enriched membranes to allow oxygen molecules in the air to pass preferentially, and concentrates them through physical devices to produce oxygen. Oxygen-enriched membrane oxygen production mechanism oxygen technology is relatively simple, the technical level is low, but the oxygen produced by this oxygen production method is about 30% concentration of oxygen, which can be used for long-term oxygen therapy and health care, and under severe hypoxia The first aid required can only use medical high-concentration oxygen.

This type of oxygen generator is currently a popular oxygen generation technology, and the oxygen generation effect is determined by the quality of the molecular sieve and compressor. Molecular sieve is a kind of particles with many small pores of different diameters. These small pores are only a few microns. Therefore, it is possible to choose which molecules can pass through and which cannot according to the size of molecules in the air. This kind of oxygen production technology uses the physical method of molecular diameter to absorb oxygen from the air without any side effects. This kind of oxygen generator can be used for physical therapy and health care. The oxygen concentration is generally about 30%-90%, and the oxygen concentration and flow can be adjusted. It is also more convenient to use. You can choose the right one according to your condition. Oxygen concentration.

The oxygen generators on the market are generally based on the molecular sieve principle, which is safer, longer in use, more cost-effective, and more stable.
