One liter machine is only suitable for general healthy people, and oxygen has little health care effect.
The two-liter machine has a certain health care function, especially for mental workers, the elderly and sub-healthy people.
The three-liter oxygen generator will have a certain oxygen therapy effect.
The five-liter machine has a wide range of applications. It is suitable for severe cases such as pulmonary edema, pulmonary heart disease and asthma, and people who need oxygen for a long time, and can play a good role in relieving patients with sudden shortness of breath.
How to choose:
The principle of molecular sieve is generally adopted in domestic oxygen generators, so the adsorption performance and service life of molecular sieve are very important, and its installation process is also very critical. When purchasing, you should choose an oxygen generator with integrated metal structure and automatic early warning filling of molecular sieve.
For patients with respiratory and cardiovascular diseases, the performance requirements of domestic oxygen generators are more demanding. When purchasing, choose a machine that can meet the standard medical indicators and provide oxygen for a long time.
Household oxygen generator is a medical care equipment, not a healthy and fashionable product. There is no need to choose a deformation machine that is not suitable for fancy appearance, but a machine with excellent structural performance, small size and ideal heat dissipation.
Having an oxygen generator certified by ISO international and CE European quality system is an important guarantee for purchasing. In addition, the time to market is also very important. It is best to choose a machine that is more than two years old.
When purchasing an oxygen generator, you should choose an oxygen generator/compressor manufacturer with a long history and strong strength. After-sales maintenance and parts replacement of household oxygen generators are very important. Only manufacturers with long brands can guarantee sustainable development and future maintenance services.
According to the relevant research of FDA, the average user needs about 3 liters of oxygen per minute at 90% concentration, so users are advised to choose high-flow machines.
Maintenance:
It is necessary to regularly check the humidifying water tank of small household oxygen generator and clean up the dirt in the humidifying water tank. This is conducive to the cleaning of oxygen, especially for friends who directly inhale oxygen, and ensure the cleanliness of the humidified water tank.
Check the compressor operation system of small household oxygen generator regularly to see if there is any air leakage. If there is any leakage, it should be repaired in time, otherwise the oxygen outlet pressure will not meet the requirements, which will affect the effect of oxygen production and oxygen absorption.
Check the air drying system of small household oxygen generator. Check the dryer and oil-water separator to clean up the impurities inside. The method is to blow air into the oxygen outlet through the mouth to increase the internal pressure. Then open the oxygen outlet valve to exhaust. Repeat the operation several times, and the impurities in it can be eliminated.
Check whether the interface between the oxygen suction pipe and the oxygen outlet of the small household oxygen generator is aging and leaking. If there is leakage, the pressure at the oxygen inhalation outlet will decrease, which will affect the oxygen inhalation effect. It is best to replace the oxygen inhalation tube regularly.
