The home oxygen generator is easy to use, portable and lightweight, and suitable for use by a large number of health care providers. Car home dual-use type, can be suitable for home use, can also be used in the car using car power.

Today's standard of living is getting better and better. Everyone knows how to keep in good health. It's almost Chinese New Year. I buy an oxygen generator for my family and care for their health. Now that living conditions are better, we should pay more attention

With the continuous improvement and improvement of people's living standards, the demand for health is gradually increasing, and oxygen inhalation will gradually become an important means for family and community rehabilitation. However, many patients and oxygen users do not know enough about oxygen inhalation, and oxygen therapy is not standardized. Therefore, the question of who needs to inhale oxygen and how to inhale it is a knowledge that every patient and user must understand.

Hypoxia hazard

Oxygen generator is suitable for people who are in oxygen therapy and oxygen care:

1. People who are prone to hypoxia: middle-aged and elderly people, pregnant women, students who have been engaged in mental work for a long time, company employees, government officials, etc .;

2. High altitude hypoxia:

student

The current state of education in our country leads to greater pressure on students. Longer periods of study and thinking are the main reasons for students' stress. These are likely to make students slowly lack of oxygen, often nausea, dizziness, insomnia, poor mood, At this time, safe and reasonable oxygen supplementation is necessary!

Oxygen is fundamental to keeping the brain's memory functioning well. During high-intensity learning, the brain load increases, and the oxygen consumption also increases sharply. When the brain cells cannot get enough oxygen, the memory will become narrower and thinner, and the memory will also decline.

This will directly affect candidates' learning ability and examination ability, and will further aggravate psychological anxiety, thereby forming a vicious circle. Nourishing can quickly restore blood oxygen concentration, enhance oxygen supply to the brain, and improve memory and thinking ability. So that brain function is quickly restored and improved. Oxygen is the most basic source of life energy for brain cells.

Middle-aged and elderly

As the elderly grow older, the body's resistance is also declining, and various functions have been unable to absorb sufficient oxygen components for the body to absorb, application, oxygen carrying capacity has decreased! In particular, when humans enter old age, the physiological functions of the human body are degraded, causing insufficient blood and oxygen supply to various tissues, especially the brain, heart, and lungs. Prolonged hypoxia will cause a variety of senile diseases, which will lead to physical deficiency. Oxygen, if not treated in time, will form long-term chronic hypoxia! And often we have many high-risk diseases caused by chronic hypoxia!

Regular oxygen in the home can prevent the occurrence of elderly diseases and delay

Electronic oxygen generator

Electronic oxygen generators are more common in pharmacies. They use the process of oxidizing and reducing the precipitation of oxygen in the air, so it does not produce dangerous hydrogen like electrolyzed water to make oxygen. The whole machine runs relatively quietly, but the requirements for this type of product are very strict during handling and use. Never tilt or invert it, or its solution will flow into the oxygen tube and spray into the nasal cavity, causing serious damage to the user. At the same time, the use of oxygen generation process is easy to produce other oxides, and the produced oxygen contains chemical substances. This type of oxygen generation method consumes large power.

The standard of living is getting better and better. Everyone knows how to keep in good health. The home oxygen machine is easy to use, portable and lightweight, and suitable for the majority of health care people. But how to choose a suitable home oxygen generator? Here to talk about the attention to choose a home oxygen generator?

Buy oxygen generator

1. Household oxygen generators generally use the principle of molecular sieve to make oxygen, so the adsorption performance and service life of molecular sieve are very important, and the installation process is also very critical. When purchasing, you should choose a metal integrated structure with automatic warning filling of molecular sieve. oxygen machine.

2. For patients with respiratory and cardiovascular diseases, the performance requirements of home oxygen generators are higher. When purchasing, you should choose a machine that can meet the standard medical indicators and provide continuous oxygen supply for a long time.
3. The home oxygen generator is a medical health device, not a health fashion article, so there is no need to choose a deformed appearance that is not suitable for fancy appearance, but a machine with excellent structural performance, small size, and ideal heat dissipation.

4. The oxygen generator with ISO international and CE European quality system certification is an important guarantee for purchase. In addition, the time to market for the product is also important. It is best to choose a machine that has been in the market for more than two years.

5. When choosing an oxygen generator, choose a long-established and strong oxygen generator / oxygen manufacturer. After-sales maintenance and parts replacement of home oxygen generators are important. Only manufacturers with a long brand can guarantee sustainable development and future maintenance. service.

6. According to relevant FDA research, the average user needs about 3 liters of oxygen per minute at a concentration of 90%. It is recommended that users choose high-flow machines.

7. The remote control is not a necessary function. This function has certain risks in medical treatment. The absorption rate of oxygen-absorbing wheat is actually very low and can be almost ignored.

8, with cumulative timing function. It can count the service life of the oxygen machine in order to provide objective and accurate data for long-term maintenance and service in the future. International standards require that the oxygen generator be equipped with a cumulative timer, which is also a reflection of the quality of the product. A good oxygen generator must have a service life of 10,000 hours.

1. Patients who purchase oxygen generator should read the instructions carefully before using.

2. Avoid open flames when using oxygen generators to avoid fire.

3. The oxygen generator should be placed stably, otherwise the noise of the oxygen generator will increase.

4. The water level in the humidification bottle should not be too high (the water level should be half of the bottle body), otherwise the water in the bottle will easily escape or enter the oxygen pipe.

5. When the oxygen generator is not used for a long time, please cut off the power supply, drain the water in the humidification bottle, wipe the surface of the oxygen generator, cover it with a plastic cover, and store it in a dry place without sunlight.

6. When the oxygen generator is turned on, do not set the flowmeter float to the zero position.

7, use

Oxygen therapy

1, especially at night should be oxygen.

2. The scientific choice of oxygen therapy time; for some patients with mild hypoxia, oxygen therapy can be performed for half an hour to 1 hour a day; for patients with severe bronchitis, cardiovascular and cerebrovascular disease and severe asthma Said that home oxygen therapy experts recommend more than 12 hours of oxygen therapy daily to ensure that sufficient oxygen is needed daily.

3. Select an appropriate oxygen flow rate. For general hypoxic patients, an oxygen flow of 2L ~ 3L / min can be selected for oxygen therapy. For patients with severe hypoxia, an oxygen flow rate of 5L / min or more is suitable. . It is best to consult the relevant treating physician and select the oxygen flow according to the actual situation of the patient.

4. The water in the humidified water tank must be replaced frequently; generally, when the water in the humidified water tank is slightly turbid, you must replace and clean the humidified water tank at this time. Home oxygen therapy experts suggest that the water in the humidified water tank should be replaced and washed once a day to ensure oxygen hygiene.

5. Nasal plug-type and nasal suction-type oxygen suction tubes should be cleaned and disinfected regularly; it is best to sterilize daily, and new nasal plug-type and nasal suction-type oxygen suction tubes should be replaced every week. The combination of the third point and the fourth point can maximize the oxygen inhalation hygiene.

6. Pay attention to the safety measures during oxygen therapy; because oxygen has combustion-supporting properties, it should be kept away from open flames when inhaling oxygen and placed in a cool and ventilated place when not using a domestic oxygen generator.

Considerations for oxygen therapy

(1) Closely observe the effect of oxygen therapy, such as reducing or relieving symptoms such as dyspnea, and a normal or near-normal heartbeat, indicating that oxygen therapy is effective. Otherwise, the cause should be found and dealt with in a timely manner.

(2) It should not be too long for high-concentration oxygen supply. Generally, it is believed that oxygen inhalation concentration> 60%, which lasts for more than 24 hours, may cause oxygen poisoning. (3) The administration of high concentration of oxygen inhalation to patients with acute exacerbation of chronic obstructive pulmonary disease may cause respiratory depression and worsen the condition. Generally, it is appropriate to give controlled (that is, continuous low concentration) oxygen inhalation.

(4) Pay attention to warming and humidification in oxygen therapy. Maintaining the temperature of 37 ° C and 95% to 100% humidity in the respiratory tract is a necessary condition for the normal clearing function of the mucociliary system. Therefore, inhaled oxygen should pass through the humidification bottle and the necessary heating device In order to prevent the inhalation of dry and cold oxygen, it can damage the airway mucosa, cause dry sputum and affect the "scavenger" function of cilia.

(5) To prevent pollution and clogging of the catheter, nasal congestion, oxygen delivery catheters, humidification heating devices, ventilator piping systems, etc. should be regularly replaced and cleaned and disinfected to prevent cross infection. The oxygen inhalation catheter and nasal obstruction should be checked at any time for clogged secretions and replaced in time. To ensure effective and safe oxygen therapy.

1. Regularly check the humidification water tank of the small domestic oxygen generator and clean the dirt inside the humidification water tank. This is conducive to the cleaning of oxygen, especially for friends who directly absorb oxygen, but also to ensure the cleaning of the humidified water tank.

2. Regularly check the operation system of the compressor of the small domestic oxygen generator to see if there is any air leakage. If there is a leak, it must be repaired in time, otherwise the pressure at the oxygen outlet will not reach the required level, which will affect the oxygen production and oxygen absorption effect.

3. Check the air drying system of the small domestic oxygen generator. Check the dryer and oil-water separator to remove any impurities. The method is to blow into the oxygen outlet first with a mouth to increase the internal pressure. Then open the oxygen outlet valve to vent. Repeat the operation several times to remove the impurities inside.

4. Check whether the interface between the oxygen absorbing tube and the oxygen outlet of the small domestic oxygen generator is aging and leaking. If there is a leak, it will reduce the pressure of the oxygen absorbing outlet and affect the oxygen absorbing effect. It is best to replace the oxygen absorbing tube regularly.

5. Check the atomizer of the small household oxygen generator to ensure that there is sufficient water in it, otherwise the produced oxygen is too dry, and long-term inhalation of dry air or people who are sensitive to the respiratory tract will have a bad effect. It is best to replace the water in the atomizer regularly to ensure that it is clean and adequate.
