Medical oxygen generator is a kind of medical equipment that uses pressure swing adsorption and other technologies to extract oxygen from the air. It is suitable for oxygen therapy and health care at medical institutions and families.

The common type of medical oxygen generator is pressure swing adsorption oxygen generator, which uses pressure swing adsorption technology to produce oxygen and can extract oxygen from the air. The medical oxygen generator is filled with molecular sieve, and the outer area of each gram of molecular sieve can reach 800-1000m2/g. Under the condition of pressure, the physical adsorption technology and desorption technology of molecular sieve are used to adsorb nitrogen in the air without being adsorbed. The oxygen will be collected, and by purifying it, oxygen with relatively high purity can be obtained. Under the condition of decompressing the molecular sieve, the previously adsorbed nitrogen gas will be re-emitted into the air. When pressurized again, nitrogen can be adsorbed to produce oxygen. Therefore, the medical oxygen generator can complete the periodic cycle of oxygen production, which is a dynamic process.

The oxygen production process of the medical oxygen generator (pressure swing adsorption oxygen generator) is shown in the figure. The oxygen production raw material is air. After the air is filtered (to remove oil, dust, moisture, solid impurities, etc. in the air), it enters the compressor. After compression, the compressed high-pressure air enters the adsorption tower for adsorption and separation after cooling. The adsorption tower is equipped with molecular sieves, in which nitrogen and carbon dioxide will be adsorbed by molecular sieves. The gas flowing out of the adsorption tower is oxygen with relatively high purity, which can be used as Medical oxygen. The separately obtained partial oxygen enters the gas storage tank through the one-way valve, and is decompressed by the pressure reducing valve, and then flows out through the flow meter and humidification bottle for the user to use; another partial oxygen is used for backflushing and cleaning the adsorber in the desorption state. The desorbed nitrogen is discharged through the muffler.

The main benefits are as follows:

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

2. Health care function: Improve the oxygen supply of the body through oxygen supply, and achieve the purpose of oxygen supplementation 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 levels of hypoxia. It can also be used to eliminate fatigue and restore physical function after heavy physical or mental exhaustion.

3. The oxygen generator is 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, physical exercise centers, plateau military stations and other oxygen-using places.

The main functions of the oxygen concentrator:

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 serious hypoxia diseases.

The oxygen generator is 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, physical exercise centers, plateau military stations and other oxygen-using places. However, oxygen concentrators for home assisted therapy shall not be used for life support or life assurance. The product must be used under the guidance of a doctor according to the prescribed daily use time and flow rate, thereby reducing the risk of improper selection of indications.
