Classification of hyperbaric oxygen chamber, chamber specific composition structure and chamber equipment configuration (seek details)

To know what is hyperbaric oxygen therapy, first let us understand what is high pressure. As we all know, from the surface of the earth to 2000 kilometers high altitude there is air, so each of us are subjected to the weight of the atmosphere itself added pressure, that is, atmospheric pressure. If you are on an airplane, you will feel uncomfortable in your ears whenever the airplane takes off or lands quickly, and this is how the human body feels the change of atmospheric pressure. How much is atmospheric pressure? The atmospheric pressure measured at sea level at 45 degrees latitude and 0 degrees Celsius is called one atmosphere, which is equal to the weight of 1 kilogram per square centimeter of body surface area (the international standard unit on the barometer is 0.1 MPa, i.e., 0.1 megapascals). When the pressure exceeds one atmosphere, we call it high pressure. We are all familiar with submarines and divers, who are subjected to high pressure when diving, and for every 10 meters of dive, the pressure increases by one atmosphere. To achieve a hyperbaric environment on land, there must be a special high-pressure resistant and sealed device, which is a hyperbaric chamber. The method in which patients are pressurized and oxygenated in a hyperbaric chamber to treat a disease is called hyperbaric oxygen therapy.　Hyperbaric oxygen chamber can be divided into two types: multi-person chamber and single person pure oxygen chamber. Single pure oxygen chamber is with pure connection direct pressurization, lying treatment; and multi-people chamber is pressurized with compressed air, to reach a certain therapeutic pressure, before wearing a pilot's mask inhalation of oxygen. Hyperbaric oxygen chamber shape more oval, like a spaceship, the patient is like a cosmic pilot, sitting on a high pillow couch, in the soft light of books, read newspapers, enjoy music, very cozy. When pressurized to a predetermined therapeutic pressure, they put on a mask to inhale oxygen, as if in space travel. Medical personnel in the cabin outside the console, through the advanced electronic computer automatic control system, control the cabin pressure, temperature, humidity, oxygen concentration and the amount of oxygen, and through the plexiglass and color closed-circuit television system, closely observe the patient, if necessary, but also to the patient's cardiovascular monitoring, in order to ensure the safety of the treatment.　A natural medical method The so-called natural medical method is the use of a non-invasive and no side effects, so that the body to strengthen the ability to resist disease and eliminate the pain of the disease. Hyperbaric oxygen therapy follows this principle of treatment. As we all know, the human body continuously inhales oxygen and exhales carbon dioxide every moment to carry out metabolism. The transportation of gases takes place through blood circulation. If certain blood vessels are defective or the blood flow is obstructed, the corresponding parts of the body will not receive sufficient blood supply, and a state of ischemia and hypoxia will occur, resulting in diseases, such as cerebral arteriosclerosis, cerebral thrombosis, coronary heart disease and so on. To address this situation, the doctor will put the patient in the hyperbaric oxygen chamber, pressurization, oxygen absorption, so that the partial pressure of blood oxygen increases, oxygen diffusion in the tissues of the scope of increase, thereby reducing the ischemic parts of the hypoxic state. At the same time, it promotes the establishment of collateral circulation in the ischemic area, opens the blocked blood vessels, improves the blood supply, enhances the metabolism and vitality of ischemic and hypoxic tissue cells, and accelerates the healing of the lesion. Therefore, hyperbaric oxygen therapy is different from general medical treatment.　Cabin "flying" out of the story In recent years, the development of hyperbaric oxygen medicine very quickly at home and abroad (such as the United States, Germany, Japan, Russia and other countries) has been widely used in clinical departments, and achieved good therapeutic effects. It is acute and hypoxia, craniocerebral injury, cerebral infarction, transient ischemic attack, vascular headache, migraine, Meniere's syndrome, coronary artery disease, bronchial asthma, chronic skin ulcers, neonatal hypoxic-ischemic encephalopathy and other diseases have a better role, especially for acute harmful gas poisoning (such as carbon monoxide poisoning) of the salvation, there is a curative effect. Thus from the hyperbaric oxygen chamber "flying" out of a magical story: Story one: a retired old cadres from the Nanjing Military Region, in a city suddenly suffered from cerebral infarction, left hemiplegia, stayed in the hospital after two months of conventional treatment, the condition gradually improved, but still can not walk. After treatment with hyperbaric oxygen, the patient was able to walk. It is said that one day due to traffic congestion late, in front of the hospital after getting off, and hastily called his lover to run first to the hyperbaric oxygen chamber to notify the late closure of the cabin. His lover ran for a while, and then turned back to tell the patient to walk slower in case he fell. Who expected to turn around and see, the patient even jogging to catch up.　Story No. 2: On July 17, 1996, a big hotel in a city suddenly caught fire, smoke, many residents due to inhalation of large quantities of carbon monoxide and other harmful gases and acute poisoning, rescue from the scene and then sent to the hospital for treatment. Some severely poisoned patients were quickly sent to the Hyperbaric Oxygen Unit, and some of them were in a comatose state. Under the direction of the head of the department, the chamber was immediately opened for hyperbaric oxygen therapy. From 5 a.m. to 8 p.m., every two and a half hours to treat a batch of patients, all get timely treatment, have saved lives. One of the most touching scenes is that a father and daughter were admitted to the cabin for treatment at the same time. Daughter is only 10 years old, poisoning is heavier, was in a deep coma; father poisoning is lighter, by hyperbaric oxygen therapy for one hour, the father came to his senses, learned that his daughter is still in rescue, struggling to climb out of the car to visit his daughter, but the body is too weak to move, then pleaded with the doctor in tears, must save his daughter. The doctor comforted the father, while nervously rescuing his daughter. After two hours of treatment, the daughter finally came to her senses.　Hyperbaric oxygen therapy has added one more magic weapon in the hands of doctors. Of course, not any disease can do hyperbaric oxygen therapy, the patient must be by the hyperbaric oxygen specialist doctor detailed physical examination, a clear diagnosis, and to determine no contraindications, to enter the cabin treatment.
