Now household oxygen generators have become a must-have for many families. However, I believe that many people have doubts. Is it necessary for me to prepare one for my family? If you plan to buy, what else should you pay attention to?

What is an oxygen concentrator?

Oxygen concentrator is a type of machine for producing oxygen. Using air separation technology, it can produce high-concentration oxygen, and then provide oxygen therapy to people in need to improve their body's hypoxic condition.

There are four main principles of oxygen production: electrolysis of water, polymer oxygen-enriched membrane, chemical reaction oxygen production and molecular sieve oxygen production.

• Electrolyzed water oxygen generator:

Use electrolysis of water to extract oxygen, built-in decomposition device with electrodes, and need to add water continuously. This kind of oxygen generator has a short service life, the machine cannot be tilted, and cannot be moved casually. The power consumption is relatively large, and transportation and use need to be carried out under the guidance of professionals.

• Oxygen-enriched membrane oxygen generator:

Oxygen production with oxygen-enriched membranes is to use the characteristics of polymer oxygen-enriched membranes to allow oxygen molecules in the air to pass through preferentially to collect oxygen, but the oxygen concentration is often not high enough, so it is generally used for daily oxygen therapy and health care.

• Chemical reaction oxygen generator:

In a container with an inhalation function, a special medicament made by a certain ratio of formula is placed to make oxygen. This mode is costly, inconvenient, and has certain dangers, and is not suitable for family use.

• Molecular sieve oxygen generator:

Using molecular sieve physical adsorption and desorption technology, through gas separation, oxygen is directly extracted from the air without any additives, ready to use. Not only is it safe and environmentally friendly, but the cost is also very low. At present, the principle of molecular sieve oxygen production is mostly used in the market. Generally, household use can be divided into two categories: health-care and medical-use oxygen generators. Health-care oxygen generators refer to oxygen generators with a flow rate of 1-2L per minute. Mainly. The flow rate of the medical oxygen generator is more than 3L per minute. The oxygen concentration of the medical grade oxygen generator needs to be stable at (93±3)%, and it must work continuously for 24 hours and 365 days.

When do you need an oxygen generator?

Under normal circumstances, the people who need to use oxygen machines mainly include the following categories:

• People living in plateau areas for a long time: Due to the low oxygen concentration in plateau areas, people living in plateau areas for a long time, especially those from plain areas, are prone to hypoxic symptoms. Using an oxygen generator can effectively improve this situation;

• Patients with respiratory diseases: such as chronic obstructive pulmonary disease (COPD), emphysema, bronchial asthma, etc. These illnesses may prevent the body from getting enough oxygen to the body, requiring the use of an oxygen concentrator to assist breathing;

• Patients with cardiovascular disease: patients with cardiovascular disease have impaired heart function and cannot effectively transport oxygen to various parts of the body, resulting in hypoxia in the body. Using an oxygen generator can prevent the body organs from being in a state of hypoxia or hypoxia. Relieve symptoms such as tachycardia, dyspnea, and shortness of breath due to hypoxia;

• Elderly people: With age, the functions of various organs of the body gradually decline, and symptoms of hypoxia are prone to occur. Using an oxygen generator can make up for the insufficient oxygen supply caused by the decline in physiological functions and maintain the normal functions of various organs of the body;
• People who are prone to brain hypoxia: "sub-healthy" office workers, people with excessive stress, people with insomnia, pregnant women, etc. are more prone to cerebral hypoxia. Oxygen therapy with an oxygen generator can help them improve their brain hypoxia and relieve discomfort. If you have any of the above situations at home, you can consider preparing an oxygen generator at home.

How to choose a suitable oxygen generator?

Before purchasing an oxygen generator, you need to consider the following aspects:

• Flow parameter: The flow parameter of the oxygen generator indicates the amount of oxygen that can be delivered per minute, generally in liters per minute. At present, the flow rate of oxygen generators in the market mainly has parameters of 1L, 3L, 5L, 6L, 8L and 10L. Different groups of people need different amounts of oxygen, which need to be selected according to individual conditions. For example, in order to relieve insomnia and high-pressure people with stress, 1L or 3L is enough. People who are hypoxic in the respiratory system can refer to the doctor's advice. Usually, medical oxygen generators above 5L are the main ones. Therefore, if the budget is sufficient, you can directly choose a 5L medical model with adjustable flow rate. use;

• Oxygen concentration: When choosing an oxygen concentrator, it is not only about the flow rate, but also about the oxygen concentration. Oxygen concentration refers to the purity of oxygen in the output oxygen, generally expressed as a percentage. The oxygen concentration of the oxygen generator with a flow rate of more than 3L must reach 93%±3 to meet the standard;

• Stable oxygen generation: Most of the people who use oxygen generators are people with basic diseases, chronic diseases and postoperative rehabilitation. They also have higher requirements for the stability of oxygen supply of oxygen generators. Patients with chronic lung disease need 15-18 hours or even 24 hours of oxygen inhalation every day. This requires the product to be able to continuously supply oxygen with a stable oxygen concentration. If the oxygen concentration fluctuates during oxygen therapy, it will not only affect the effect, but may even cause more serious accidents;

• Noise level: Oxygen concentrators will produce a certain amount of noise when they are working. There will be instructions on the outer packaging of each product, but it is just a reference. You can check more information and choose products with lower actual noise;

• Weight and volume: For indoor use, the weight and volume of the oxygen generator need to be considered, and a product with a suitable size can be selected according to the indoor space;

• Service life: The oxygen generator needs to be used for a long time. In order to avoid frequent replacement, it is necessary to purchase a machine with good quality and long service life. In addition, it should be noted that the less the oxygen generator is used, the more likely it will cause the molecular sieve to be damp and invalid, resulting in a decrease in oxygen production efficiency and concentration. Therefore, more attention should be paid to daily use and maintenance.

There are many types of oxygen generators on the market, but the quality varies greatly, so don't just consider the price factor when purchasing. For personal comparison, it is recommended to give priority to big brands, and the quality and service are more guaranteed. Like DEDAKJ home oxygen generator DE-1A 1B DE-2A 2SW and 10 liter medical oxygen machine , its performance in terms of quietness, stability and durability is not bad, not to mention the service, it can be considered if you need a 5L oxygen generator.

Do you need to buy an oxygen concentrator? What kind of oxygen concentrator should I buy? It is also necessary to choose according to the situation of individual family members. If you or your family members have any physical discomfort during oxygen inhalation, you should also seek medical treatment in time.

The function of the oxygen concentrator is to help people who have difficulty breathing and obtain enough oxygen through their own respiratory system to inhale oxygen. From this point of view, the oxygen generator has the effect of health care and auxiliary treatment for some special groups of people.

Who needs to use an oxygen machine?

Generally speaking, those who need to use oxygen generators can be roughly divided into three categories.

1, young people with high work and study pressure and poor mental sleep.

2, pregnant women

3, the elderly who suffer from high blood pressure, heart disease, asthma and other diseases.
