Oxygen enriched membrane oxygen generator "oxygen enriched membrane" is a thin film with the function of enriching oxygen. Oxygen enriched membrane is based on membrane separation technology, which can utilize the different permeability of various components in the air when passing through the membrane under a certain pressure, enrich oxygen in the air under pressure difference, and achieve a concentration of 30% outlet oxygen. It has the advantages of small volume and low power consumption. It can be used for long-term oxygen therapy and healthcare, while emergency treatment required in severe hypoxia can only use medical high concentration oxygen.
Molecular sieve oxygen generator (pressure swing adsorption oxygen generator) is an advanced gas separation technology. Using physical methods (PSA method) to directly extract oxygen from the air, it is ready to use, fresh and natural, with a maximum oxygen production pressure of 0.2-0.3MPa (i.e. 2-3 kilograms), and there is no danger of high pressure explosion.
Chemical agent oxygen generator is a device that uses a reasonable formula of chemicals and is used in specific situations. It can indeed meet the urgent needs of some consumers. However, due to the simplicity of the equipment, the difficulty of operation, the high cost of use, the need to invest a certain amount of money in each oxygen inhalation, and the inability to use continuously, it is not suitable for home oxygen therapy.
Electronic oxygen concentrators are commonly found in pharmacies, which use the process of oxidizing and reducing oxygen from the air in a solution. Therefore, they do not produce dangerous hydrogen gas like electrolytic water oxygen concentrators, and the whole machine runs relatively quietly. However, this type of product requires very strict handling and use, and must not be tilted or inverted, otherwise its solution will flow into the oxygen delivery tube and spray into the nasal cavity, causing serious damage to the user. The simultaneous use of oxygen production processes can easily generate other oxides, and the oxygen produced contains chemicals. This type of oxygen production method consumes a lot of electricity. According to experts, the best electronic oxygen generators in the world have a service life of less than 1000 hours. During use, it is necessary to ensure that the solution has the appropriate concentration, otherwise oxygen cannot be produced normally. Customers who choose electronic oxygen generators must do a good job in maintenance.
