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, people who suffer from tuberculosis, or who have had part of their lungs removed for other reasons, people who have a reduced number of alveoli, people who have emphysema, and people who suffer from respiratory distress due to pneumoconiosis where the function of the alveoli has deteriorated, and so on, are in a critical condition due to the fact that the partial pressure of oxygen in their arterial blood is as low as 50-60 𪾹, which is the lowest level of oxygen in the blood. In such cases, it is generally ideal to supply 30-40% oxygen-enriched air. This is exactly the optimal concentration range for membrane oxygen enrichment.
Relating to the specific effect of oxygen medical treatment, chronic closed-type lung disease patients as an example, there have been many cases can be confirmed to have the effect of prolonging life, oxygen compared with no oxygen, the cumulative mortality rate fell by an average of about 60%, but also can significantly shorten the number of days of hospitalization. For example, the average number of hospitalization days for patients without oxygen is at least 9 days and up to 40 days, while the average number of hospitalization days for patients with oxygen is at least 1 day and up to 4 days, which is nearly 10 times shorter. At the same time, 24 hours a day oxygen intake than 12 hours a day oxygen intake effect is better, the average cumulative mortality rate decreased by about 1/3. When people engage in intense exercise, the pulse rate and respiratory rate increase. The mechanism of exercise is explained by the fact that in the body, nutrients react with oxygen in the tissues and the resulting energy is used to promote muscle movement, while carbon dioxide and lactic acid are produced when oxygen is consumed, and the pulse and respiration increase dramatically in order to replenish oxygen and discharge carbon dioxide. But what is the best way to take in oxygen? The following are the results of the relevant tests: ① when exercising while inhaling oxygen, compared with inhaling ordinary air, the number of heart beats is reduced, and the whole body endurance is improved; ② when exercising after inhaling oxygen, i.e., inhaling oxygen in advance is only to play a kind of reserve role. b fatigue recovery Generally speaking, fatigue after exercising is due to the increase of lactic acid in the blood, which can be disappeared with the help of oxygen supplementation. Therefore, after intense exercise, inhaling high concentration of enriched oxygen as soon as possible will rapidly restore fatigue.C Improvement of wakefulness effect and recognition abilityWhen people work under the situation of insufficient oxygen supply for a long time, such as the pilot of a military airplane without pressurization under the condition of low-pressure environment at a high altitude, they will be affected both physically and mentally. The establishment of oxygen-enriched room in plateau has been Cui Jianhua, Zhang Xizhou and Ha Zhende of the 18th Hospital of the PLA have published more than ten papers to prove that it can improve the sleep quality, thinking, behavior and working ability of the migrants, enhance the energy metabolism of plateau organism, and it is the ideal measure for plateau troop to improve the exercise ability of the organism and to resist the fatigue and so on, which is a kind of more ideal way of supplying the oxygen in plateau.5.2 Oxygen absorbing equipment Oxygen absorbing equipment mainly includes Membrane oxygen concentrator, PSA oxygen concentrator, chemical oxygen concentrator and deep-cooling oxygen concentrator, etc. Among them, membrane oxygen concentrator is the most competitive. Among them, the membrane oxygen concentrator is the most competitive and applicable. See Figure 2, where the plate membrane module is only A4 paper size, thickness of 1cm or so, while Figure 3 is a set of learning photos while inhaling oxygen. The weight of which personal use membrane oxygen concentrator is less than 4 kilograms, very light and easy to carry. Currently more fashionable membrane oxygen bar air conditioning (see Figure 4) is extracted from the outdoor oxygen content of only 21% of the air, after oxygen-rich membrane processing oxygen content rapidly increased to about 30%, effectively solving the problem of dizziness due to the confined space oxygen is too low and the impact of dizziness, eye strings, breathing is not smooth and so on. In addition, oxygen bar air conditioning oxygen bar function and fresh air technology can also run independently, in the absence of cooling, heating, run alone oxygen bar and fresh air function, not only to maintain air circulation and cleanliness in the living room, but also to increase the oxygen content in the air, acting as an oxygen bar to use alone, an effective solution to the current situation, the use of air-conditioning consumers the process of health and comfort of the contradiction. In 2003, can eat while inhaling oxygen oxygen bar opened one after another in Japan, in the process of people's pursuit of health, inhalation of oxygen has become a craze. What triggered this boom was the membrane oxygen-enriched supply unit and oxygen-enriched air conditioner, which were launched in March 2003 by Panasonic Corporation. Modern homes are becoming more and more airtight, and indoor air can easily become dirty. If air with a high concentration of oxygen can be delivered to indoor areas, the effect of freshness can be obtained indoors as well as outdoors, and this is the selling point of Panasonic's oxygen-enriched supply units and oxygen-enriched air conditioners. This unprecedented new breakthrough in the field of old-fashioned home appliances has won the favor of users, and in less than a year after its launch, the sales of the two products have reached about 12 billion yen (about 923 million yuan). On January 15, 2004, Panasonic released a new oxygen-enriched supply unit and an oxygen-enriched air conditioner. It also released four other products, including an oxygen-enriched water heater that allows people to breathe freely even in bathrooms where air circulation is difficult. The company intends to increase sales of oxygen-enriched products to 50 billion yen (about 3.85 billion yen) by FY2004 by continuously expanding its product lineup.6 Oxygen-enriched waterWhen people think of oxygen, they tend to think that it can only exist in a gaseous state. Unbeknownst to them, a type of oxygen-enriched water suitable for drinking is now available. Through drinking water, we can also supplement oxygen for the body. The benefits of oxygen-enriched water compared to ordinary drinking water are indisputable. It can supply a large number of oxygen molecules to the human bloodstream, making it provide a quick and beneficial oxygen lift. In addition, it can be used to clean food, vegetables, fruits, etc.; keeping these organic materials free from bacteria, removing odors from them and maintaining their natural essence. Water with oxygen content ≥20mg/l is generally referred to as oxygen-enriched water. Oxygen-enriched water is called "revolutionary drink" by the world beverage industry, once introduced, caused a strong reaction and a huge sensation in the U.S. beverage industry, "for human beings from the contaminated water source, the lack of oxygen in the air to free themselves from the opening of a new pathway", as "A profound revolution in today's beverage industry", the authoritative "Beverage Network" commentators in the U.S. beverage industry commented that: "LifeO2 Super Oxygenated Life Water (oxygen-enriched water) not only restores one's physical strength, but also energizes one's body, and it is the purest water that can be used in the world. It is the purest energy-boosting drink and a revolutionary product." September 22, 1998 & lt; & lt; Beijing Economic News & amp; & amp; published an article that says: "Experts believe that oxygen and water are known as the natural world's "source of life", "the essence of life "The invention of oxygen-enriched water is a great contribution to mankind, and it will be a superior beverage in the 21st century, widely used in bottled water and various beverages, medicine and health care, beauty care, environmental protection and other fields, and it plays an important role in the maintenance of ecological balance of the nature. Oxygen-enriched water is still relatively unknown in our country, while there are many foreign manufacturers producing "oxygen-enriched water". If the container is properly selected, the dissolved oxygen in "oxygen-enriched water" can reach 70mg/L, 10 times that of ordinary water. Oxygen is an important and indispensable substance in life activities, and the occurrence, development and deterioration of many diseases are related to lack of oxygen. Preliminary research has found that drinking oxygen-rich water is beneficial to the health of the cardiovascular system; many people feel refreshed after drinking "oxygen-rich water"; some people's headache disappears after drinking; athletes can improve their athletic ability after drinking. Oxygen can inhibit and kill the anaerobic bacteria that cause "bad breath", tooth decay and gum disease, "oxygen-enriched water" is a great blessing for patients with oral diseases. If the use of mineral water rich in trace elements to produce "oxygen-enriched water" can also be achieved to prevent disease and fitness for a variety of purposes.7 Domestic membrane oxygen-enriched health care for the progress of the situation, to be honest, the domestic membrane oxygen-enriched research units are many, but due to a variety of reasons, the development of successful oxygen-enriched health care equipment is relatively small, and the application of the development of the even less. In fact, the application of oxygen-enriched health care will be more and more extensive with the continuous improvement of people's life! Especially the membrane method of oxygen enrichment, compared with other sources of oxygen supply with simple operation, safety, economy, long-term use of oxygen poisoning will not occur and other characteristics, more value of popularization and use. Dalian Institute of Chemical Physics, Chinese Academy of Sciences membrane center has done some work in this area: ① and the Second Hospital of Dalian Medical College and the Third People's Hospital in Dalian, for the rehabilitation of chronic lung diseases. Chronic respiratory diseases resulting in hypoxemia, medical experts at home and abroad that advocate long-term low-flow oxygen therapy daily oxygen therapy time of 15 hours, oxygen-enriched commonly used concentration of 22-27%, the clinical significance of which is: to reduce the erythrocyte depressurization, blood viscosity, alleviate pulmonary vasospasm, reduce pulmonary vascular resistance, increase the right cardiac discharge, improve the body's oxygen supply to prolong life expectancy and reduce mortality. Currently, the oxygen supply sources for oxygen therapy are oxygen cylinders, liquid oxygen storage devices and oxygen-enriched generators. Oxygen enriched generators can be further categorized into adsorption and membrane methods. In the evaluation of these three sources of oxygen, that the membrane method of oxygen enricher has a small size, simple operation, do not need to be replaced, safe, reliable and economic advantages, the cost is only one quarter to one-thirtieth of the oxygen cylinder, and the efficacy of the reliable, for the rehabilitation of the medical engineering to add a new content; ② and the Dalian Municipal Sports Commission, the Dalian Municipal Sports Commission, under the Dalian Sports School of the long-distance sprinters application shows that: oxygen can promote the body after exercise, acid-base balance. The oxygen-enriched room shows that the visual reaction time is significantly shortened after oxygen intake, the stability of movement is significantly improved, and the knocking movement is more sensitive and rapid. Oxygen-enriched room in plateau can improve the hypoxia of workers, enhance the heart function, improve the efficiency of labor, and it is a very ideal way of supplying oxygen in plateau; ④ and the Nanjing Plateau Rehabilitation Hospital of the Ministry of Railways and Xining Railway Bureau of Qinghai cooperated, and set up an oxygen-enriched room in the driver's room of the train between Guanjiao Station of Gelmu Mechanical Section of Qinghai (elevation of 3,650m) and Keke Station (elevation of 2,900m) and conducted dozens of hourly tests: the average increase of blood oxygen partial pressure (BP) increased significantly, the knocking action was more rapid. Tests: the partial pressure of blood oxygen rises 7.3mmHg on average, the average increase of blood oxygen saturation is 3.4%, and in the oxygen-enriched environment, the tested person has the feeling of relaxation, fatigue easy to eliminate, and the brain is more awake; ⑤ and the First Engineering Agency of the 18th Bureau of the Ministry of Railways, the First Engineering Agency*** together in the Lenglongling Tunnel of Qilian Mountain at the junction of Gansu and Qinghai Provinces (elevation of up to 3,429 meters), the first time to apply the membrane method oxygen-enriched technology to the plateau tunnel, and establish a membrane-enriched technology in the highland tunnel. Plateau tunnel, the establishment of a mobile oxygen bar, good tunnel operation workers severe hypoxia, for the plateau oxygen-deficient areas of the operators to provide a new way of thinking and development direction to improve the oxygen supply conditions, for China's plateau operation for labor protection has accumulated scientific data. Table 3 is a comparison table of the oxygen concentration test of the MFY1608 oxygen-enriched equipment provided by us. From the test results, the original oxygen content of the air at the air inlet is an important factor affecting the effect of oxygen enrichment, and the lack of original oxygen content in the plateau area reduces the oxygen enrichment efficiency from 7% to about 3%. The use of membrane oxygen enrichment technology to build a mobile oxygen bar in the cave is a bold and useful attempt, but due to the small cross-section of the tunnel and the harsh working conditions in the cave, the device in the cave during the use of some of the defects need to be improved. It is believed that through technical improvement, this method will be widely promoted in the future in the field of labor protection such as improving workers' hypoxia in the plateau area with its advantages of simple equipment, less investment, easy operation, low operation cost, etc. Other methods are incomparable; 6) cooperated with Dalian Instrumentation Group, *** with the development of a number of personal use of small-scale membrane oxygen-enrichment machine, and by the Chinese People's Liberation Army 210 Hospital clinical application, the effect is good! The product was clinically applied in 210 Hospital of the Chinese People's Liberation Army with good effect, and obtained the market access license from Liaoning Medical Device Product Quality Supervision and Inspection Station. Later, due to the Dalian Instrumentation Group was merged and other reasons and suspended; (7) on the "oxygen bar" air conditioning and the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, the earliest and the Dalian Membrane Center contact is Kelong, followed by Chunlan, the last is Haier. Mainly for Haier and so on to provide "oxygen bar" air conditioning in the core components: plate and frame oxygen-rich membrane components. For home use "Oxygen Bar" air conditioner, the size of its plate and frame oxygen-enriched membrane component is only as small as A4 paper, with a thickness of about 1 cm. This "Oxygen Bar" air conditioner utilizes the characteristic that oxygen molecules pass through the oxygen-enriched membrane faster than other gas molecules, so that the oxygen concentration of the oxygen-enriched membrane is increased from 21% to 30%. Oxygen concentration from 21% to 30% or so, so that the human body in a long-term fresh air environment. The oxygen bar of this air conditioner can also be used separately, which greatly satisfies people's need for oxygen. Air conditioning can produce oxygen, will become the future of the air conditioning industry standard, this innovation, the development of the air conditioning industry has a revolutionary significance, is a milestone in the development of the air conditioning industry.8 Typical domestic introduction of the oxygen bar A, FAW workers into the "Oxygen Bar" the first oxygen bar in the heat treatment plant of the FAW Group Company of China put into use, front-line workers in the "Oxygen Bar". The first oxygen bar was put into use in the heat treatment plant of China FAW Group Corporation, and the front-line workers breathed pure air in the "oxygen bar". According to Zhao Chunren: FAW Group Company heat treatment plant front-line workers in the production of large amounts of exposure to carbon monoxide and a variety of harmful gases, which seriously affects the physical and mental health of workers. 1993 the plant's physical examination of the workers, found that 27% of the electrocardiogram has changed. After analysis, in addition to the specific nature of the production decision (four shifts per year, three times), the operating environment is a big factor, the parts of the high-temperature quenching produces a large amount of fumes, suction port and can not be sucked out all of them, carburizing furnace exhaust 24 hours a day, non-stop exhaust and combustion of fumes and combustion of exhaust containing a large amount of carbon monoxide and other toxic and hazardous substances, so the entire operating site in the air oxygen content is much lower than the normal oxygen content of ordinary air. Therefore, the oxygen content of the air in the whole work site is much lower than the normal oxygen content of ordinary air. It is difficult for new workers to adapt to this harsh environment after entering the factory, and they often suffer from headaches, dizziness and nausea, etc. In particular, workers on the third shift often feel sick. In particular, the workers in the third shift often felt weak and depressed, and sometimes suffered from irregular heart rate, nausea and vomiting. Later, the factory changed all the original 40 natural suction air into mechanical ventilation and built an oxygen absorbing room for the workers to do one step in dust poison treatment and prevention of occupational diseases. The oxygen absorbing room uses compressed air or clean outdoor air as the air source, and the pure oxygen-rich oxygen obtained from the oxygen generator is fed into the room through the pipeline or oxygen absorbing mask or inhaled directly into the mouth of the workers, and the original oxygen content of the production workshop is 18-20%, while the oxygen content of the oxygen absorbing room is 25-27%. By resting in the oxygen absorbing room, workers' fatigue dissipates quickly and they are refreshed, clear-headed and energetic. After several years of use, the workers' response is good, and they all say it is worthwhile to enjoy a while in the oxygen bar. Practice has proved that the oxygen absorption room for long-term exposure to carbon monoxide and other toxic and hazardous substances is undoubtedly a method worth promoting.B, plateau "oxygen bar" in the plateau, the oxygen bar, oxygen-rich room is more. Such as the construction of the Kunlun Mountain Tunnel of the Qinghai-Tibet Railway, in the face of the cold climate of plateau construction, severe oxygen deficiency and other challenges to the physiological limits of the severe test, they adhere to the people-oriented, the establishment of a staff dormitory oxygen-rich room at the site, finally realized the tunnel through the target ahead of schedule. Cui Jianhua, Zhang Xizhou and Zhang Jianlin from the 18th Hospital of PLA and Urumqi Military Medical College established an oxygen-enriched room at an altitude of 5,380m, increased the concentration of indoor oxygen enrichment to 27-28%, and carried out stepping exercise before and after the oxygen enrichment of 27.3% of 10 healthy youths at the plateau at an altitude of 5,380m to check the content of superoxide dismutase, glutathione peroxidase and malondialdehyde in the blood. The results demonstrated that oxygen enrichment had a significant inhibitory effect on free radical damage in plateau exercise and was important for enhancing the aerobic pathway. Plateau hypoxia affects all tissue systems of human beings, and the effect becomes more serious with the increase of altitude. Plateau combat squads perform tasks before or after the completion of the task in the oxygen-enriched room sleep for a night, to improve combat effectiveness, recovery due to extreme hypoxia caused by the lack of compensatory function of the organism is very beneficial. And this kind of measure is easy to popularize and apply in plateau medical unit and border guard post, which has obvious effect on reducing the occurrence of exercise fatigue, enhancing energy metabolism and improving the efficiency of plateau operation. At the same time, oxygen-enriched room is an ideal oxygen supply pathway to prevent the occurrence of plateau disease, which has certain application value in clinical treatment and basic research.9 Oxygen Therapy and Oxygen Health Care Development Prospects Oxygen for human survival and health is important, no matter how to emphasize it can not be overemphasized. The emergence of oxygen therapy and oxygen health care means that the human demand for oxygen is transformed from complete dependence on nature to further conscious striving, opening a new chapter in the history of human and oxygen. Oxygen therapy and oxygen health care are the products of the development of the whole society and civilization. Without the development and accumulation of physiology, clinical medicine, preventive medicine and emergency medicine, and without the development and accumulation of chemistry, especially peroxide chemistry, oxygen therapy and oxygen health care would not have been possible. Oxygen therapy and oxygen health care are also the needs of the development of the whole society. The people demand a high quality of life and a healthy life. As pointed out in the Charter of the World Health Organization, "'health' is the state of physical, mental and social perfection of the human being, not merely the absence of disease and infirmity". Oxygen therapy and oxygen health care can promote the overall physical and mental health: full of energy, the ability to withstand tension and stress; enhance self-confidence and enterprising spirit; prolong youth, the ability to slow down the aging process; improve the body's ability to resist disease, reduce the occurrence of disease; once the disease occurs, improve the ability to reduce symptoms, faster recovery and avoid sequelae. Oxygen therapy and oxygen health care is also the need to shift the focus of health work to the prevention and treatment of non-communicable diseases and lifestyle diseases. The reality of today's world shows that the pace of life is accelerating, the pressure of competition is increasing, and the intensity of knowledge expansion and mental labor is also increasing. Coexisting with this is the worldwide trend of aging, and the difficulty of curbing atmospheric, especially urban atmospheric, pollution. Oxygen therapy and oxygen health care can play a unique and positive role in the prevention and treatment of non-communicable diseases and lifestyle diseases. Scientific research on oxygen therapy and oxygen health care has been emphasized worldwide, and people's understanding of the complex mechanisms by which oxygen supply affects human physiology and pathology will continue to deepen. With the deepening of understanding, oxygen therapy and oxygen health care will be further widely used in preventive medicine, clinical medicine, occupational medicine, sports medicine, maternal and child medicine, geriatrics, etc., and will be included in the scope of every doctor's consideration of the treatment plan to play a greater role in curing diseases and saving lives. Medical reports indicate that breathing appropriate oxygen can keep the mind awake, enhance memory, make blood circulation smooth, and can prevent arteriosclerosis, dementia, cancer, etc.; Oxygen inhalation also has a great effect on asthma, recovery from fatigue, regulation of blood pressure, restoration and enhancement of weakened cardiopulmonary function; In addition, the most sensitive part of the human body to oxygen is the brain, and pregnant women who give oxygen to their babies through the placenta can give birth to intelligent babies; Aerobic exercise is also an important part of the body's oxygen management. Oxygen supply to the fetus through the placenta of pregnant women can give birth to smart babies; aerobic exercise is also an effective treatment for diabetes; sufficient oxygen supply can also activate the blood circulation of the skin, making the skin healthy and elastic. With the continuous emergence of new membrane materials, the continuous improvement of membrane technology and the continuous decrease of membrane cost, the function is becoming more and more perfect, coupled with the safety, simplicity, reliability, long service life and no side effects of membrane oxygen, oxygen therapy and oxygen health care will be popularized to tens of thousands of households, remote areas, mountain posts, field work, underground mines, so that people can use it to improve their health. Oxygen therapy and oxygen health care will be widely recognized among all kinds of people, and will enter the fields of education, work, competition, leisure and beauty care, and become an integral part of modern life style. Oxygen therapy and oxygen health care will be combined with the popularization of aerobic metabolic exercise in the population to enhance the ability of the human body to inhale, transport and use oxygen; and make more contributions to the development of human physical potential, intellectual potential, mental potential and social potential.
Membrane Oxygen Enrichment Technology Principle of Oxygen Enrichment
Membrane Oxygen Enrichment is to utilize the different permeation rate of each component of the air through the membrane, and driven by the pressure difference, to make the oxygen in the air pass through the membrane preferentially to get the oxygen-enriched air. With this membrane for multi-separation, you can get oxygen-enriched air containing more than 30% oxygen. Oxygen-enriched membrane research in the medical, fermentation industry, chemical industry, oxygen-enriched combustion and other important applications.
