1, the oxygen concentration output by the oxygen generator must be greater than 90%, which can be detected by the oxygen monitoring device provided by instruments or machines.
2. The oxygen generator with constant cumulative timing function should be selected to provide objective and accurate data for long-term maintenance and service in the future. Equipped with cumulative timer is a mandatory requirement of international standards, and it is also the embodiment of product quality. The service life of oxygen generator (oxygen generator) should be guaranteed for tens of thousands of hours.
3. Choose a low-noise oxygen generator (oxygen generator), the noise level should be lower than 45 decibels, otherwise it may affect the rest of yourself and others, especially at night.
4. Choose an oxygen generator with a large compressor displacement (3.8-4.2m3/h), otherwise it will be easy to wear and tear after long-term operation, resulting in insufficient gas volume and attenuation of oxygen concentration. The leather wrist of the compressor is very important, so it is best to use imported parts.
5. The influence of molecular sieve on machine performance is not as great as expected, mainly due to its adsorption performance and service life, but the filling process of molecular sieve is very critical. Molecular sieve tower and tank are integrated metal structures, so it is very important that the performance of molecular sieve is full of mechanical early warning. However, the performance of oxygen generator (oxygen generator) with plastic end cover, rivet riveting and manual filling of molecular sieve is bound to be greatly affected.
6. For patients with lung diseases such as respiratory or heart failure, hypoxemia and chronic obstructive pulmonary disease, medical-grade oxygen generators that can keep the oxygen concentration up to standard under 24-hour uninterrupted working conditions should be selected.
7. The oxygen generator is a medical device, not a healthy and fashionable device, so the preferences of size and appearance will vary from person to person. However, considering that some patients need to be turned on for a long time, we must choose a machine with moderate size, optimized internal structure and ideal heat dissipation space. Only by comprehensively improving the heat dissipation performance can the oxygen concentration be stable.
8. Choose an oxygen generator (oxygen generator) that has been tested for a long time and passed the iso international and ce European quality system certification. After the general products are put on the market, the quality will have a running-in period, and the performance may be unstable in the first two years. Therefore, we should pay attention to the time when the product enters the market and whether it has passed the relevant certification.
9, to choose a strong, long-term sustainable development of oxygen machine (oxygen machine) manufacturers, as well as local institutions to improve after-sales service. At present, due to the variety and uneven quality of oxygen generators, the strength of manufacturers varies greatly, and the survival of the fittest is bound to face the reshuffle of the oxygen generator industry. This point must also attract the attention of users. If the brand is eliminated, it will be difficult to guarantee long-term after-sales service for your purchase.
10. Different grades of oxygen generators (oxygen generators) should be selected according to the severity of illness and economic ability, and "price" and "value" should be considered together to avoid falling into the vicious competition vortex of oxygen generator brands. Pursue low "price" blindly and ignore the "value" that should be. It may bring many bad consequences.
