[0002] A medical oxygen concentrator is a medical device that uses pressure swing adsorption and other technologies to extract oxygen from the air. It is suitable for oxygen therapy and health care in medical institutions and homes. The raw material for oxygen production is air. After being filtered (to remove oil, dust, moisture, solid impurities, etc. in the air), the air enters the compressor for compression. The compressed high-pressure air is cooled and then enters the adsorption tower for adsorption and separation. The adsorption tower is equipped with a molecular sieve, and the nitrogen and carbon dioxide in it will be adsorbed by the molecular sieve. The gas flowing out of the adsorption tower is oxygen with relatively high purity and can be used as medical oxygen.
