Introduction to the Principle of Home Oxygen Concentrator

May. 05, 2022

Oxygen is a colorless, odorless gas that is an important substance for human survival. Oxygen is used in a wide variety of industries, including the healthcare industry. The home oxygen concentrator is suitable for the majority of health care practitioners because of its convenient use, lightweight and other characteristics. Nowadays, there are many kinds of household oxygen generators on the market. Due to the different principles of oxygen generation, the use characteristics of each household oxygen generator are also different. The oxygen principle of household oxygen production mechanism includes: 1.The principle of chemical reaction oxygen production; 2.The principle of electrolysis of water; 3.The principle of oxygen-enriched membrane; 4.The principle of molecular sieve.

Introduction to the Principle of Home Oxygen Concentrator

The first: the principle of chemical reaction oxygen production

Probably we all learned a lot of chemical knowledge about oxygen production in middle school. What the teacher taught us at that time was to use potassium permanganate to decompose and use manganese dioxide as a catalyst to produce oxygen. This is the first chemical oxygen production we came into contact with. There are similar oxygen generators on the market now, which cannot be called oxygen generators. Because he is just a container with an inhalation function, he needs to constantly buy medicines to produce oxygen. The biggest advantage of this oxygen concentrator is that it is cheap when you buy it for the first time, but the follow-up cost is expensive, and you can only inhale for 15 minutes each time you put the medicine. In addition, it is chemical oxygen production, and there will be some side effects of producing other gases to some extent. However, its oxygen concentration is very high, which can reach 90%. For people who need first aid, oxygen can be replenished in time. However, due to the simple equipment, troublesome operation and high cost of use, each oxygen inhalation needs to invest a certain cost, and it cannot be used continuously and many other defects are not suitable for home oxygen therapy.


The second: the principle of electrolysis of water

 Electrolyzed water, as the name suggests, is to use electricity to split water to extract oxygen. There must be an electrode decomposition device in it, and water must be continuously added. This kind of oxygen generator is expensive, but the service life is shorter, and the machine cannot be tilted or moved casually, and the power consumption is also very large, otherwise it will be damaged and the stability will be poor. Generally, household oxygen generators rarely use this type of oxygen generator. method, which is used more in industry.


The third type: principle of oxygen-rich membrane

 Oxygen-enriched membrane is based on the principle of selective permeation of organic polymeric membranes. The oxygen-enriched membrane allows oxygen molecules in the air to pass through preferentially, and is concentrated through physical devices to produce oxygen. Oxygen-enriched membrane oxygen production mechanism The oxygen technology is relatively simple and the technical level is low, but the machine using this oxygen production method produces oxygen with a concentration of about 30%, which can be used for long-term oxygen therapy and health care. First aid required is only medically high concentration of oxygen.


The fourth: molecular sieve principle

This type of oxygen generator is a popular oxygen generation technology, and the oxygen generation effect is determined according to the quality of molecular sieve and compressor. Molecular sieves are particles with many pores of different diameters. These pores are only a few microns, so it can choose which molecules can pass through and which cannot be based on the size of the molecules in the air. This oxygen production technology uses the physical method of molecular diameter to absorb oxygen from the air, and has no side effects at all. This type of oxygen generator can be used for physical therapy and health care. The oxygen concentration is generally around 30%-90%, and the oxygen concentration and flow can be adjusted. It is also more convenient to use. You can choose the appropriate oxygen concentration according to the improvement of your condition.
