If you are unable to take in a normal amount of oxygen for some reason, you 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-rich air. This is the optimal concentration range for membrane oxygen enrichment.
As for 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 extending life. Compared with those without oxygen, the cumulative mortality rate is reduced on average. Around 60, it can also significantly shorten the length of hospitalization. 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. substantial increase. But what is the best way to breathe oxygen? The following are the results of relevant tests: ① When exercising while breathing oxygen, compared with breathing ordinary air, the number of heartbeats is reduced and the whole body endurance is improved; ② When exercising after breathing oxygen, that is, breathing oxygen in advance only has a Reserve function. B Recovery from Fatigue Under normal circumstances, the feeling of fatigue after exercise is caused by the increased lactic acid in the blood, which can be eliminated with the help of oxygen supplement. Therefore, after intense exercise, inhaling high-concentration oxygen as soon as possible will quickly restore fatigue. C. Improve wake-up effect and recognition ability. When people work under conditions of insufficient oxygen supply for a long time, such as military aircraft pilots without pressurization function in high-altitude and low-pressure environmental conditions, they will be affected both physically and mentally. Cui Jianhua, Zhang Xizhou, Ha Zhende and others from the 18th Hospital of the People's Liberation Army have published more than ten papers proving that the establishment of an oxygen-enriched room on the plateau can improve the sleep quality, thinking, behavior and working ability of immigrants, and can enhance the plateau body Energy metabolism is an ideal measure for plateau troops to improve their physical exercise capacity and resist fatigue. It is also a relatively ideal way to supply oxygen to plateaus. 5.2 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. See Figure 2, in which the plate membrane module is only the size of A4 paper and about 1cm thick, while Figure 3 is a set of photos of learning while absorbing oxygen. Among them, the personal membrane oxygen enrichment machine weighs less than 4 kilograms, which is very light and easy to carry. The currently more fashionable membrane oxygen bar air conditioner (see Figure 4) 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 problem of low oxygen in a confined space. Problems such as dizziness, blurred vision, and difficulty breathing. In addition, the oxygen bar function and fresh air replacement technology of the oxygen bar air conditioner can also operate 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. Used alone as an oxygen bar, it effectively solves the contradiction between health and comfort when consumers use air conditioners under the current circumstances. In 2003, oxygen bars that allowed people to inhale oxygen while eating were opened one after another in Japan. As people pursued health, oxygen inhalation became a craze. What sparked this craze was Panasonic's membrane oxygen-enriched supply machine and oxygen-enriched air conditioner, which were launched in March 2003. Modern homes are becoming more and more airtight, and indoor air can easily become polluted. If air with a higher oxygen concentration can be delivered indoors, you can get the same fresh effect indoors as outdoors. This is the selling point of Panasonic's oxygen-enriched supply machine and oxygen-enriched air conditioner.
This unprecedented new breakthrough in the field of old-fashioned home appliances has won the favor of users. Less than a year after its launch, the sales of the two products have reached about 12 billion yen (approximately RMB 923 million). Panasonic released a new oxygen-enriched supply machine and oxygen-enriched air conditioner on January 15, 2004. It also released four other products, including an oxygen-rich water heater that allows people to breathe freely in bathrooms where air circulation is difficult. The company plans to increase sales of oxygen-related products to 50 billion yen (approximately RMB 3.85 billion) by 2004 by continuously expanding its product lineup. 6 Oxygen-enriched water When it comes to oxygen, people often think that it can only exist in a gaseous state. As everyone knows, now, a kind of oxygen-enriched water suitable for drinking has been released. By drinking water, we can also replenish oxygen to the body. Compared with ordinary drinking water, the benefits of oxygen-enriched water to the body are unquestionable. It can supply a large amount of oxygen molecules to human blood, providing a quick and beneficial oxygen lift. In addition, it can also be used to clean food, vegetables, fruits, etc.; to protect these organic substances from bacteria, remove odors from them, and maintain their natural essence. Water with an oxygen content ≥20mg/l is generally called oxygen-rich water. Oxygen-enriched water is called a "revolutionary drink" by the world's beverage industry. Once it came out, it caused a strong response and a huge sensation in the American beverage industry. It "opened up a new way for human beings to free themselves from polluted water sources and oxygen-deficient air." approach", regarded as "a profound revolution in today's beverage industry." A commentator from the authoritative "Beverage Network" in the U.S. beverage industry commented: "LifeO2 super oxygenated life water (oxygen-rich water) can not only restore people's physical strength, but also It is the purest energy-enhancing drink and a revolutionary product that makes people energetic." An article published by Beijing Economic News on September 22, 1998 said: "Relevant experts believe that oxygen and water. It is known as the "source of life" and "the foundation of life" in nature, and the invention of super oxygenated life water, that is, oxygen-rich water, which combines the two into one, is a huge contribution to mankind and will be a world-famous product in the 21st century. Superior drinks will be widely used in bottled water and various beverages, medicine and health care, beauty, environmental protection and other fields. It plays an important role in maintaining the ecological balance of nature. Oxygen-enriched water is still relatively unknown in our country, and there are many manufacturers abroad. "Oxygen-enriched water". If the container is properly selected, the dissolved oxygen in "oxygen-enriched water" can reach 70mg/L, which is 10 times that of ordinary water. Oxygen is an indispensable and important substance in life activities and is responsible for the occurrence and development of many diseases. , deterioration is related to hypoxia. Preliminary research has found that drinking oxygen-enriched water is beneficial to the health of the cardiovascular system; many people feel refreshed after drinking "oxygen-enriched water"; some people have headaches that disappear after drinking it; athletes can improve their health after drinking it. Exercise ability. Oxygen can inhibit and kill anaerobic bacteria that cause bad breath, tooth decay and gum disease. "Oxygen-enriched water" is a great boon for patients with oral diseases if they use mineral springs rich in trace elements. The production of "oxygen-enriched water" can also achieve various purposes of disease prevention and fitness. 7. The progress of domestic membrane oxygen enrichment for medical care. To be honest, there are many domestic research units on membrane oxygen enrichment, but due to various reasons, development has not been completed. There are relatively few successful oxygen-enriched health care equipment, and even less application development. In fact, the application of oxygen-enriched health care will become more and more widespread as people's lives continue to improve! The oxygen source is relatively simple to operate, safe, economical, and does not cause oxygen poisoning in long-term use. It is also valuable for promotion and use. The Membrane Center of Dalian Institute of Chemical Physics, Chinese Academy of Sciences has done some work in this area: ① and Dalian Medical College. The Second Affiliated Hospital and Dalian Third People's Hospital cooperate to treat hypoxemia caused by chronic respiratory diseases. Domestic and foreign medical experts believe that long-term low-flow oxygen therapy should be carried out for 15 hours a day and be enriched with oxygen. Commonly used concentrations are 22-27, and its clinical significance is: reduce hematocrit, blood viscosity, relieve pulmonary vasospasm, reduce pulmonary vascular resistance, increase right heart output, increase the body's oxygen supply, prolong life, and reduce current oxygen death. The oxygen supply sources of therapy include oxygen cylinders, liquid oxygen storage tanks and oxygen-enriched generators. Oxygen-enriched devices can be divided into adsorption methods and membrane methods.
The reality of today's world shows that the pace of life is accelerating, competition pressure is increasing, knowledge expansion and the intensity of mental work are also increasing. Coexisting with this is the global aging trend, and air pollution, especially in urban areas, is difficult to contain. Oxygen therapy and oxygen health care can play a unique positive role in the prevention and treatment of non-communicable diseases and lifestyle diseases. Scientific research on oxygen therapy and oxygen health care has received worldwide attention, and people's understanding of the complex mechanisms in 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, geriatric medicine and other fields, and will be included in the thinking scope of every doctor when considering treatment plans, so as to treat diseases and save lives. Play a bigger role. Medical reports indicate that breathing appropriate oxygen can keep the mind clear, enhance memory, smooth blood circulation, and prevent arteriosclerosis, dementia, cancer, etc.; oxygen inhalation can also restore asthma, fatigue, regulate blood pressure, restore and improve the condition of weakness. Cardiopulmonary function has a great effect; in addition, the most sensitive part of the human body to oxygen is the brain. Pregnant women can give birth to smart babies by providing oxygen to the fetus through the placenta; 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-making materials, the continuous improvement of membrane-making processes, the continuous decline of membrane-making costs, the increasingly perfect functions, and the advantages of membrane-based oxygen production such as safety, simplicity, reliability, long life and no side effects, oxygen therapy and oxygen Health care will be spread to thousands of households, remote areas, mountain outposts, field work, and underground mines, so that the people can use it to improve their health. Oxygen therapy and oxygen health care will be widely recognized among various groups of people, entering fields such as education, work, competition, leisure, and beauty, and become an integral part of modern lifestyles. Oxygen therapy and oxygen health care will be combined with the popularization of aerobic metabolic exercise among the population to enhance the human body's ability to inhale, transport, and use oxygen; and make more contributions to unleashing people's physical, intellectual, mental and social potential. .
Principle of oxygen enrichment using membrane oxygen enrichment technology
Membrane oxygen enrichment utilizes the different permeability rates of each component in the air when passing through the membrane. Driven by the pressure difference, the air is enriched. Medium oxygen preferentially passes through the membrane to obtain oxygen-rich air. Using this membrane for multiple separations, oxygen-rich air containing more than 30% oxygen can be obtained. Research on oxygen-rich membranes has found important applications in medical treatment, fermentation industry, chemical industry, oxygen-rich combustion, etc.
