However, 30% of the oxygen is produced by this oxygen generator, which can be used for ltot and health care. The first aid needed in severe hypoxia can only be medical high-concentration oxygen. Molecular sieve oxygen generator is an advanced gas separation technology.
Physical method (PSA method) directly extracts oxygen from the air, which is fresh and natural. The maximum oxygen pressure is 0.2 ~ 0.3 MPa (2 ~ 3 kg), and there is no danger of high-pressure explosion. The invention adopts a reasonable chemical formula and is used in specific occasions. It can really meet the urgent needs of some consumers.
However, due to the simple equipment, troublesome operation and high use cost, each oxygen inhalation requires a certain amount of money, and it cannot be used continuously, which is not suitable for home oxygen therapy! At present, electronic oxygen generator is common in pharmacies, which adopts the process of oxidation and reduction of oxygen in the air in solution, and will not produce dangerous hydrogen like electrolysis of water to make oxygen, so the whole machine runs quietly.
However, the handling and use of such products are very strict, and it is absolutely not allowed to tilt or invert, otherwise its solution will flow into the oxygen delivery tube and spray into the nasal cavity, causing serious harm to users.
At the same time, other oxides are easily produced in the process of oxygen production, and the produced oxygen contains chemical substances. This method of making oxygen consumes a lot of electricity. According to experts, the service life of the best electronic oxygen generator in the world can hardly exceed 1000 hours. In the process of use, it is necessary to ensure that the solution has a suitable concentration, otherwise oxygen cannot be produced normally. Customers who choose electronic oxygen generator must do a good job of maintenance! 1. To select the model with an oxygen concentration of 90% from the oxygen generator, the oxygen concentration can be detected by the oxygen monitoring device provided by the instrument or machine.
2. The noise level of the oxygen generator is preferably less than 45 decibels. The oxygen generator is an electrical appliance that works for a long time. The sound must not be too loud, otherwise it will affect the rest of yourself and others, especially at night, so the motor sound at work should be low. 3. A good manufacturer of oxygen machines should have oxygen machines (oxygen machines) certified by ISO international and CE European quality system, and pay attention to brands that have been listed for more than two years, so as to have better quality assurance and related certification. 4. Strong oxygen production ability. The displacement of the compressor is preferably 3.8-4.2 cubic meters per hour. In this way, in the living room with large space, the oxygen generator with large exhaust capacity can ensure that every corner of the space can have sufficient oxygen supply. 5. It has the cumulative timing function. It can count the service life of oxygen machine and provide objective and accurate data for long-term maintenance and service in the future. International standards require that the oxygen generator be equipped with an accumulative timer, which is also the embodiment of product quality. A good oxygen generator should have a service life of tens of thousands of hours.
