Medical Molecular Sieve Oxygen Generator Oxygen Concentrator

With the increasing air pollution, and the increasing number of lung disease patients. Oxygen concentrators are becoming more and more popular medical devices. Whether it is oxygen inhalation for health care or home oxygen therapy, there is a great demand for oxygen concentrators.

Although sales are increasing and the frequency of use is increasing, most people do not know the "insider details" of oxygen concentrators. There are different perceptions of whether it is producing oxygen or filtering oxygen. Many people think that the oxygen generator focuses on the filtration system in the propaganda, so the oxygen generator is to filter the oxygen in the air for patients to inhale oxygen.

But what is the truth, perhaps understanding the working principle of the oxygen generator can reveal the answer.

Oxygen concentrator is a kind of machine for producing oxygen. Its principle is to separate oxygen and nitrogen through different adsorption capacities of adsorbents for oxygen and nitrogen under the action of pressure. Such machines generally use high-power oil-free For the power of the compressor, the molecular sieve is used as the adsorption medium, and the oxygen and nitrogen in the air are separated through the cooperation of four-way valves and other components, and finally high-concentration oxygen is obtained.

Molecular Sieve Oxygen Generator

Molecular sieve oxygen concentrator adopts physical method (PSA method), which is an advanced gas separation technology. When working, it is to extract the oxygen in the air and use it directly. Compared with other oxygen concentrators, it is safer. The resulting oxygen pressure is generally between 0.2~0.3MPa, and there will be no explosion due to high pressure.

While outputting high-concentration oxygen, the molecular sieve will discharge the adsorbed nitrogen into the air during decompression, and re-adsorb the nitrogen to produce oxygen in the next pressurization. In this oxygen production cycle, the molecular sieve will not be consumed.

However, it should be noted that although the molecular sieve, the core component, is not naturally consumed, the oxygen production performance of oxygen generators of different qualities is significantly different after working for a long time. The most intuitive manifestation is that the oxygen concentration will attenuate, which will directly lead to the deterioration of the oxygen inhalation effect, and even cause harm to the patient's health.

Therefore, in the selection of oxygen generators, users should choose a suitable oxygen generator according to their own needs. For non-therapeutic consumers, small-capacity oxygen concentrators can be effective. But for patients suffering from chronic obstructive pulmonary disease or similar serious diseases, only a medical-grade oxygen concentrator can benefit from home oxygen therapy .

Taking patients with chronic obstructive pulmonary disease as an example, the reason why it is necessary to use a medical-grade oxygen generator is because from the perspective of treatment effect, patients with chronic obstructive pulmonary disease (COPD) who receive home oxygen therapy must achieve more than 15 hours a day and continuously inhale oxygen for 500 days , in order to obtain a significant effect of oxygen therapy. Therefore, in the selection of an oxygen generator, attention must be paid to the concentration of oxygen generator and the performance of continuous work. Only when the time requirement of oxygen therapy can be met can the expected effect of home oxygen therapy be achieved.

The medical molecular sieve oxygen generator is a medical device that extracts oxygen from the air by using technologies such as pressure swing adsorption. It is suitable for oxygen therapy and health care in medical institutions and families.

The common type of medical molecular sieve oxygen generator is pressure swing adsorption oxygen generator, which uses pressure swing adsorption technology to generate oxygen, which can extract oxygen from the air. Molecular sieves are filled in the medical molecular sieve oxygen generator, and the surface area of each gram of molecular sieve can reach 800-1000m2/g. Under the condition of pressurization, the physical adsorption technology and desorption technology of molecular sieves are used to absorb nitrogen in the air, and the nitrogen in the air is not absorbed. The oxygen will be collected, and by purifying it, oxygen with relatively high purity can be obtained. In the event of depressurization of the molecular sieve, the previously adsorbed nitrogen is vented back into the atmosphere. When pressurized again, nitrogen can be adsorbed to produce oxygen. Therefore, the medical molecular sieve oxygen generator can realize periodic cycle oxygen production, which is a dynamic process.

Medical Molecular Sieve Oxygen Generator

The oxygen production process of the medical molecular sieve oxygen generator (pressure swing adsorption oxygen generator) is shown in the figure. The raw material for oxygen production is air, which is filtered (removing oil, dust, moisture, solid impurities, etc. in the air) into the compressed The compressed high-pressure air is cooled and enters the adsorption tower for adsorption and separation. The adsorption tower is equipped with molecular sieves, and the nitrogen and carbon dioxide in it will be absorbed by the molecular sieves. The gas flowing out of the adsorption tower is relatively high-purity oxygen, which can be as medical oxygen. Part of the separated oxygen enters the gas storage tank through the one-way valve, is decompressed by the pressure reducing valve, and then flows out through the flow meter and humidification bottle for the user; The nitrogen gas is discharged through the muffler.

Oxygen generators are suitable for medical institutions and families for oxygen therapy and health care.

The Main Uses are as Follows:

1. Medical function: By supplying oxygen to patients, it can cooperate with the treatment of cardiovascular and cerebrovascular, respiratory system, and so on. Diseases such as chronic obstructive pneumonia, as well as gas poisoning and other severe hypoxic conditions.

2. Health function: improve the oxygen supply status of the body through oxygen supply, and achieve the purpose of oxygen supplement and health care. It is suitable for middle-aged and elderly people, people with poor physical fitness, pregnant women, college entrance examination students and other people with different degrees of hypoxia. It can also be used to eliminate fatigue and restore body functions after heavy physical or mental exhaustion.

3. Oxygen generators are suitable for small and medium-sized hospitals, clinics, health stations, etc. in cities, villages, remote areas, mountainous areas, and plateaus. At the same time, it is also suitable for nursing homes, home oxygen therapy, sports training centers, plateau military depots and other places where oxygen is used.

The Main Function Of The Oxygen Generator

Medical function: By supplying oxygen to patients, it can cooperate with the treatment of cardiovascular and cerebrovascular diseases, respiratory system, chronic obstructive pneumonia and other diseases, as well as gas poisoning and other severe hypoxic diseases.

Health care function: Improve the oxygen supply status of the body by supplying oxygen to achieve the purpose of supplementing oxygen and health care. It is suitable for middle-aged and elderly people, people with poor physical fitness, pregnant women, college entrance examination students and other people with different degrees of hypoxia. It can also be used to eliminate fatigue and restore body functions after heavy physical or mental exhaustion.

Cardiovascular and cerebrovascular diseases The so-called cardiovascular and cerebrovascular diseases are collectively referred to as diseases of the cardiovascular and cerebrovascular diseases. Including hypertension, heart disease, coronary heart disease, myocardial infarction, cerebral thrombosis, cerebral ischemia, cerebral vertigo, atherosclerosis, etc. These diseases will make it difficult for the human body to take in oxygen, and oxygen therapy with an oxygen generator can supplement oxygen in time.

Respiratory system diseases Respiratory system diseases are common and frequently-occurring diseases. The main lesions are in the trachea, bronchi, lungs, and chest cavity. Mild lesions often cause coughing, chest pain, and respiratory problems. Severe ones have dyspnea, hypoxia, and even respiratory failure. And lethal. The death rate in the city is the third, while in the countryside it is the first. What should be paid more attention to is that due to air pollution, smoking, population aging and other factors, chronic obstructive pulmonary disease (referred to as COPD, including chronic bronchitis, emphysema, pulmonary heart disease), bronchial asthma, lung cancer, The morbidity and mortality of diseases such as pulmonary diffuse interstitial fibrosis and pulmonary infection have increased unabated. These diseases include pneumonia, bronchitis, chronic bronchitis, viral respiratory infections, asthma, emphysema, cor pulmonale, etc. The inability to take in oxygen normally has a great impact on these diseases, even death, so patients with these diseases need an oxygen concentrator for oxygen therapy.
