working principle

Working principle of household oxygen concentrator: using molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can adsorb nitrogen in the air when pressurized. The remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The molecular sieve discharges the adsorbed nitrogen back into the ambient air during decompression, and can adsorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process, and the molecular sieve is not consumed. [2]
About oxygen inhalation

With the continuous improvement of people’s living standards and the increasing demand for health, oxygen inhalation will gradually become an important means of family and community rehabilitation. However, many patients and oxygen users do not know enough about oxygen inhalation, and oxygen therapy is not standardized. Therefore, who needs oxygen and how to inhale oxygen are issues that every patient and oxygen user must understand.
Hazards of hypoxia
The harm and important manifestations of hypoxia to the human body. Under normal circumstances, hypoxia mainly has the following harms to the human body: during hypoxia, the aerobic metabolic rate in the human body is reduced, anaerobic glycolysis is strengthened, and the metabolic efficiency of the body is reduced; long-term severe hypoxia can cause Pulmonary blood vessels constrict, causing pulmonary hypertension, increasing the burden on the right ventricle, which may cause pulmonary heart disease in the long term; hypoxia can aggravate hypertension, increase the burden on the left heart, and even cause arrhythmia; hypoxia stimulates the kidneys to produce erythropoietin, which causes the body to Increased red blood cells, high blood viscosity, increased peripheral vascular resistance, increased heart burden, cause or aggravate heart failure, and easily induce cerebral thrombosis; long-term brain hypoxia can produce a series of mental and neurological symptoms: such as sleep disorders, mental decline, Memory loss, abnormal behavior, personality changes, etc. Usually, people’s hypoxia has the following important symptoms: increased breathing times, difficulty breathing, chest tightness, suffocation, cyanosis of lips and nail beds; accelerated heartbeat; due to enhanced anaerobic glycolysis, lactic acid levels in the body increase, often causing fatigue and fatigue feeling; inattention, decreased judgment and memory; nighttime sleep disorders, decreased sleep quality, daytime drowsiness, dizziness and headaches and other symptoms.
oxygen uptake
Necessary conditions and advantages of oxygen inhalation. Oxygen inhalation is sometimes called “oxygen therapy”. Although it cannot cure all diseases, it does have obvious effects on some diseases. It can not only supply oxygen to hypoxic tissues, but also dissolve blood in the blood. The bubbles can stimulate wound healing and have value in diseases such as bubble embolism, carbon monoxide poisoning, cyanide poisoning, unhealed wounds, bone injury necrosis, soft tissue infection, cerebral edema and other diseases. Providing oxygen at normal pressure to premature infants and people with serious illness or trauma is also an important life-saving measure. It can be thought that not only hypoxic patients need oxygen, but normal people also need to supplement a certain amount of oxygen in the natural environment. Such as patients with coronary heart disease, pulmonary heart disease, asthma, bronchitis and various chronic cardiovascular and cerebrovascular diseases, pregnant women, mental workers with stressful work and study, primary schools, junior high schools, high schools, universities, graduate students and other exam preparation personnel, plateau hypoxic areas Residents, tourists, etc.
Oxygen therapy
According to numerous literature reports, the main points are as follows: relieve nervous fatigue, relax the body and mind, maintain strong energy, and improve work efficiency; improve the oxygen supply to the brain, regulate the function of the brain nervous system, improve memory and thinking ability, and improve learning efficiency; Reduce the harm to the body caused by pollution and harsh environments; It can delay aging and enhance metabolism to a certain extent; Reduce hypoxemia and meet the needs of tissue metabolism; Relieve pulmonary hypertension caused by hypoxia, reduce polycythemia, and reduce blood viscosity degree, reduce the burden on the right ventricle, and delay the occurrence and development of pulmonary heart disease; oxygen inhalation can relieve bronchospasm, reduce dyspnea, and improve ventilatory dysfunction; improve the patient’s physical fitness and brain function, improve exercise endurance and quality of life; improve chronic obstructive pulmonary disease , prolong life; reduce the number of hospitalizations and save medical expenses; can reduce post-operative infections and prevent vomiting, etc.
Generally, those who meet any of the following three conditions should receive long-term home oxygen therapy: ① The clinical status is stable for 3 to 4 weeks, without acute bronchitis, pulmonary inflammation, or heart failure. The results of arterial blood gas analysis twice in a row for 2 weeks: Arterial blood oxygen therapy Partial pressure PaO2<60mmHg, blood oxygen saturation SaO2<88%. ② The clinical status is stable, and the results of at least 2 arterial blood gas analyzes are: arterial blood oxygen partial pressure PaO2 is 55-59mmHg, accompanied by secondary erythrocytosis, pulmonary hypertension or pulmonary heart disease, right heart failure, and PaO2 drops by 10mmHg after exercise. One. ③ PaO2>55mmHg during the day, but SaO2<75% at night or those with severe sleep apnea. It should be noted that oxygen therapy for patients with chronic obstructive pulmonary disease (COPD) has gradually received more attention. COPD patients suffer from simultaneous dysfunction and ventilation due to long-term ventilatory dysfunction. Imbalanced blood flow ratio leads to O2 deficiency and CO2 retention, especially nocturnal hypoxemia.
Dangers of Excessive Oxygen Inhalation
The negative effects of excessive oxygen intake As early as the mid-19th century, British scientist Paul Burt first discovered that if animals are allowed to breathe pure oxygen, it will cause poisoning, and the same will happen to humans. If a person is in a pure oxygen environment greater than 0.05 MPa (half an atmosphere), it will have a toxic effect on all cells. If the person inhales it for too long, “oxygen poisoning” may occur. The capillary barrier of the lungs is destroyed, leading to pulmonary edema, pulmonary congestion and hemorrhage, seriously affecting respiratory function, and further causing damage to various organs due to lack of oxygen. In a pure oxygen environment of 0.1 MPa (1 atmosphere), a person can only survive for 24 hours before pneumonia will occur, eventually leading to respiratory failure and death from suffocation. People can stay in a high-pressure pure oxygen environment of 0.2 MPa (2 atmospheres) for up to 1.5 to 2 hours. Exceeding this time will cause brain poisoning, disordered life rhythm, mental disorder, and memory loss. If oxygen is added to 0.3 MPa (3 atmospheres) or higher, brain cell degeneration and necrosis will occur within a few minutes, causing convulsions and coma, leading to death.
In addition, excessive oxygen intake will also promote life aging. Oxygen entering the human body reacts with oxidase in cells to generate hydrogen peroxide, which in turn becomes lipofuscin. This kind of lipofuscin is a harmful substance that accelerates cell aging. It accumulates in the myocardium, aging myocardial cells and reducing cardiac function; it accumulates in the blood vessel walls, causing blood vessel aging and hardening; it accumulates in the liver, weakening liver function; it accumulates in the brain. , causing mental decline, memory loss, and people becoming dementia; they accumulate on the skin and form age spots.
Contrary to hypoxia, oxygen deficiency occurs when there is excess oxygen, that is, if high-concentration oxygen-rich air is inhaled for a long time (usually the oxygen concentration is greater than 40%, and medical experts recommend that the optimal oxygen concentration for long-term oxygen therapy is 22-35%). Poisoning phenomenon, for example, if a mouse is exposed to pure oxygen for a few minutes, it will die; if a healthy person continuously inhales pure oxygen with a partial pressure of 0.05Mpa for 20 to 30 minutes, a severe metabolic drop will occur, resulting in fatigue and headache. Symptoms of oxygen poisoning such as hand inflexibility and inflexibility.
Oxygen Medical
If you are unable to take in a normal amount of oxygen for some reason, you will need to take certain medical measures to inhale oxygen. For example, those suffering from tuberculosis, or those who have had part of their lungs removed for other reasons, those with a reduced number of alveoli, emphysema, those with difficulty breathing due to pneumoconiosis and alveolar function decline, etc., because the partial pressure of oxygen in their arterial blood has been low. Between five and sixty, life is on the verge of crisis. In this case, it is generally ideal to supply 30-40% oxygen-enriched air. This is the optimal concentration range for membrane oxygen enrichment.
Regarding the specific effects of oxygen therapy, taking patients with chronic closed lung disease as an example, many cases have been confirmed to have the effect of prolonging life. Compared with not inhaling oxygen, the cumulative mortality rate is reduced by about 60% on average, and it can also Significantly shortened hospital stay. For example, the average length of stay for patients without oxygen is at least 9 days and up to 40 days, while for patients on oxygen the average stay is at least 1 day and up to 4 days, which is nearly 10 times shorter. At the same time, oxygen inhalation 24 hours a day is more effective than oxygen inhalation 12 hours a day, and the average cumulative mortality rate is reduced by about 1/3. When people engage in strenuous exercise, their pulse and breathing rates increase. The explanation from the mechanism of exercise is that nutrients and oxygen react in the tissues of the human body, and the energy obtained is used to promote muscle movement. At the same time, carbon dioxide and lactic acid are produced after oxygen is consumed. In order to replenish oxygen and emit carbon dioxide, the pulse and respiratory rate will increase. increased badly.
Oxygen inhalation equipment Oxygen inhalation equipment mainly includes membrane oxygen enrichment machines, PSA oxygen generators, chemical oxygen generators and cryogenic oxygen generators. Among them, the membrane oxygen enrichment machine is the most competitive and applicable. Among them, the plate membrane module is only the size of A4 paper and about 1cm thick. Among them, the personal membrane oxygen enrichment machine weighs less than 4 kilograms, which is very light and easy to carry. The more fashionable membrane oxygen bar air conditioner extracts air with an oxygen content of only 21% from the outdoors. After being treated with an oxygen-rich membrane, the oxygen content quickly increases to about 30%, effectively solving the problems of dizziness and blurred vision due to low oxygen in a confined space. , breathing difficulties and other problems. In addition, the oxygen bar function and fresh air replacement technology of the oxygen bar air conditioner can also be operated independently. Without cooling or heating, the oxygen bar and fresh air replacement functions can be operated independently, which not only maintains the circulation and cleanliness of the room air, but also increases the oxygen content in the air. When used alone as an oxygen bar, it effectively solves the contradiction between health and comfort when consumers use air conditioners.

For people

student
The current situation of education in our country has led to high pressure on students. Long-term study and thinking are the main reasons for students’ learning pressure. These can easily cause students to gradually become deprived of oxygen, often causing nausea, dizziness, insomnia, poor mood, etc. At this time, safe and reasonable oxygen supplementation is necessary!
Oxygen is fundamental to maintaining good brain memory function. During high-intensity learning, the brain load increases and the oxygen consumption also increases sharply. When the brain cells do not receive enough oxygen, the memory will become narrower and thinner, and the memory will also decrease.
This will directly affect the candidates’ learning ability and examination ability, and will further aggravate the degree of psychological anxiety, thus forming a vicious circle. Supplements can quickly restore blood oxygen concentration, enhance oxygen supply to the brain, and improve memory and thinking ability. Rapidly restore and improve brain function. Oxygen is the most basic source of life energy for brain cells.
middle-aged and elderly people
As the elderly age, the body’s resistance also decreases, and various functions can no longer absorb sufficient oxygen components for the body to absorb and apply, and the oxygen-carrying capacity decreases! Especially after humans enter old age, the physiological functions of the human body deteriorate, resulting in insufficient blood and oxygen supply to various tissues, especially the brain, heart, lungs, etc. Long-term hypoxia will cause a variety of elderly diseases, which will lead to physical deficiency. Oxygen, if not treated in time, will cause long-term chronic hypoxia! And often we have many high-risk diseases caused by chronic hypoxia!
Regular oxygen inhalation at home can prevent the occurrence of senile diseases and delay aging. It can eliminate chest tightness, shortness of breath, dizziness, irritability and other symptoms, and can play an emergency role in the occurrence of angina pectoris, cerebral thrombosis, stroke, etc.
white-collar worker
If you are a white-collar worker, do you sometimes get dizzy, have chest tightness, or feel like stars are shining in your eyes when you suddenly stand up? Or suddenly have dark vision, insomnia, memory loss, or lack of energy at work! If you have these symptoms, consider supplementing with oxygen!
White-collar workers have been exposed to air-conditioning for a long time, with closed doors and windows, dirty air, insufficient indoor oxygen content, and severe oxygen deficiency. In addition, they live irregular lives, heavy mental work, high pressure, and lack of a normal human body clock, causing imbalances in various organs of the body. . Hypoxia is the same as in the elderly. If long-term chronic hypoxia occurs, aging will be accelerated! Proper oxygen supplementation is very important for white-collar workers, as it can improve work efficiency and mental state, and relieve work stress.
pregnant woman
According to surveys, the main reasons for fetal death in the womb, premature death, mental retardation in children or neonatal diseases are caused by hypoxia. Pregnant women breathing oxygen can increase the mother’s blood oxygen content, so that the fetus can obtain more adequate oxygen, thereby more It is beneficial to the health of the mother and the growth of the fetus; the hospital has equipment that can detect fetal hypoxia, but because the pregnant woman is at home, the doctor cannot detect it in time, so by the time it is discovered, the best period of oxygen supplementation may be missed! Pay special attention to the fetus during the short period of time Multiple fetal movements within a period of time, or no fetal movement for a long time, may be caused by hypoxia. Regular oxygen inhalation can prevent such situations.
special patients
Sick people are one of the people who need oxygen the most, especially those with cardiopulmonary diseases! Equipment can be used for auxiliary treatment to speed up the improvement of the condition! Oxygen inhalation can prevent the further development of the condition and improve the immunity of the whole body and respiratory tract. It also relieves symptoms of shortness of breath, improves mental status, enhances mobility, and significantly improves quality of life; for patients with mild arteriosclerosis, liver and pulmonary dysfunction, coronary heart disease, and stroke, regular oxygen inhalation can reduce the frequency of attacks and persist for a long time. Oxygen therapy plays an important role in complete recovery from the disease.
Oxygen therapy and oxygen health care

effect
Oxygen therapy and oxygen health care use oxygen to improve the physiological and biochemical internal environment of the human body and promote a virtuous cycle of metabolic processes to achieve the purpose of treating diseases, alleviating symptoms, promoting recovery, preventing lesions, and improving health. Clinical practice has proven that oxygen therapy, with its unique therapeutic mechanism, can effectively treat acute and chronic ischemic-hypoxic diseases and secondary diseases caused by hypoxia in various clinical departments. Proper oxygen inhalation can also improve microcirculation, reduce the load on the respiratory system necessary to maintain a certain alveolar gas oxygen partial pressure, and reduce the myocardial load necessary to maintain a certain arterial blood oxygen partial pressure. Therefore, in clinical medicine, preventive medicine, emergency medicine, geriatric medicine, rehabilitation and health care medicine, oxygen therapy and oxygen health care have irreplaceable important roles and broad development prospects.
When the human body is hypoxic or about to become hypoxic, oxygen is given to increase the oxygen concentration of the inhaled gas, increase the oxygen content of the arterial blood, and improve the oxygen supply to the tissues. This is collectively called oxygen therapy. Generally speaking, oxygen therapy is used to correct pathological hypoxia and is used as an auxiliary treatment method for diseases. It is called oxygen therapy when it is used for critically ill patients and accident victims. Physiological hypoxia in people, pregnant women and patients recovering from chronic diseases, as well as supplementing various environmental hypoxia, as a way to prevent hypoxia, are called oxygen health care. Compared with other medical methods and health care methods, oxygen therapy and oxygen health care are positive
