Oxygen generators have become "hot items", the key points for purchasing


After optimizing and adjusting the epidemic prevention and control measures, oxygen generators have become household medical supplies that more and more people pay attention to. If there are elderly patients or patients with underlying lung diseases at home, keeping an oxygen concentrator can play a key role.


Oxygen generators


So, how does an oxygen concentrator work? What is the difference between home and medical use? How can I choose the one that suits me?


The principle type of oxygen production


Oxygen generators on the market mainly use physical methods to purify oxygen from the air. For example, using oxygen-enriched membrane compressed air to produce oxygen, the principle is similar to that of a water purifier. This oxygen generator can increase the oxygen concentration in the air from 21% to 40%, and is mostly used for industrial combustion and health care.


Medical small oxygen generators are mainly molecular sieve oxygen generators. Use molecular sieves to absorb nitrogen in the air under pressurized state, collect the remaining unabsorbed oxygen and purify it into high-purity oxygen, the oxygen concentration can reach 30%-90%, and it is mostly used for medical and health care.


Important parameters of oxygen generator


Oxygen production


The core parameter of the oxygen generator is the oxygen production capacity, which is usually 1, 2, 3, 5, 8, 10 liters and above. Continue to increase the flow after exceeding the limit, and the oxygen concentration will decrease with the increase of the oxygen flow.


The 1 and 2 liter oxygen generators are household health-care models, which are used for health-care oxygen inhalation for people with slight hypoxia, such as pregnant women with slight hypoxia, students and mental workers who use a lot of brains and stress.


Oxygen concentrators of 3 liters and above are classified as medical grade and belong to the second class of medical devices. The production and export must apply for a medical device registration certificate. Disease crowd. The oxygen concentration of the medical grade oxygen generator must reach 93%±3% to be considered qualified.


Note: If it is used for auxiliary treatment, you should listen to the doctor's advice to choose the oxygen generator of the corresponding specification, and it is recommended to choose 3-5 liters of oxygen generator for home backup.


Continuous oxygen supply time


Oxygen concentrators used only for health care are often small in size, poor in heat dissipation, and cannot work for a long time. Most of the medical oxygen generators used for treatment can work 24 hours a day.


For example, patients with chronic obstructive pulmonary disease and chronic respiratory failure need to inhale oxygen for no less than 15 hours a day, so it is necessary to choose an oxygen generator that can supply oxygen for a long time, so as not to meet the treatment needs.


The noise level of the oxygen generator


It is recommended to choose the noise level of the oxygen generator not higher than 48 decibels, otherwise it may affect rest. Generally, larger oxygen generators are less noisy.


When the oxygen generator is working, try not to place it in a small space or on a wooden floor, which will increase echo or other additional noise. People who are very sensitive to noise can use a longer oxygen suction tube connection to achieve the purpose of staying away from the machine.


How to choose an oxygen generator?


When purchasing an oxygen generator, it is recommended to choose an oxygen generator manufacturer or brand with strong strength, good reputation, quality assurance, and long-term sustainable development. It is best to have a local organization with perfect after-sales service. At the same time, purchase through formal channels. In addition, pay attention to the following points:


1. Clarify the purpose of oxygen inhalation


Choose an oxygen concentrator according to the maximum oxygen flow rate you need, the daily oxygen inhalation time, etc. For example, for patients with diseases such as chronic respiratory or heart failure, hypoxemia, and chronic obstructive pulmonary disease, a medical-grade oxygen generator that can still meet the standard oxygen concentration under 24-hour uninterrupted working conditions should be selected.


2. Select atomization function as needed


For example, for patients with respiratory diseases such as chronic obstructive pulmonary disease and asthma, the oxygen generator with atomization function can not only meet the oxygen supply needs, but also can conveniently carry out atomization inhalation treatment at home, reducing the cost of medical treatment.
