Hyperbaric chamber manufacturers in China have those to know
Hyperbaric oxygen chamber manufacturers, treatment equipment for various hypoxia. The cabin is a closed cylinder, and pure oxygen or purified compressed air is input through the pipeline and control system. The doctor outside the cabin can communicate with the patient through the observation window and the intercom. The large oxygen cabin has 10-20 seats.
working principle
Oxygen is carried by the blood. When oxygen enters the lungs, it will immediately dissolve in the blood. The dissolution process is like putting a spoonful of white sugar in water and it will be quickly dissolved. The amount of oxygen dissolved in the blood of a normal person is related to the environmental pressure. We live in an environment of atmospheric pressure. Since the oxygen in the air is only 1/5, there is very little oxygen dissolved in human blood, which cannot meet the needs of the human body. Oxygen easily enters the red blood cells and is transported along with the movement of the red blood cells. The oxygen dissolved in the blood is very small but very important. Because the oxygen carried by red blood cells is dozens of times higher than the oxygen dissolved in the blood, normal people can meet the oxygen intake for oxygen delivery. Such as the hyperbaric oxygen experiment: the Dutch scientist experiment in 1956. The blood of the piglet is drawn from the artery and then saline is injected from the vein, and then put into the hyperbaric oxygen chamber and added with three atmospheres of oxygen. The piglet lives in this hyperbaric oxygen chamber for 15 minutes, and the blood is reinfused into The piglet is still alive after its body. The piglet continues to live by dissolved oxygen. Scientists named this experiment a bloodless life. After many experiments, it is concluded that the oxygen dissolved in the blood in the hyperbaric oxygen chamber increases as the pressure of the oxygen chamber increases. The oxygen dissolved in the blood increased by 14 times after inhaling pure oxygen in a 2 atmospheres oxygen chamber, and it increased by 21 times at 3 atmospheres.
Scope of application
Hyperbaric oxygen is suitable for the following diseases: gas, hydrogen sulfide, biogas and other harmful gas poisoning, cerebral thrombosis, cerebral hemorrhage, brain trauma, neuritis, vasculitis, diabetic gangrene, difficult-to-heal ulcers, fetal developmental failure, neonatal asphyxia, Acute air embolism, decompression sickness, altitude sickness, sudden deafness, Meniere syndrome, vertigo. The inhaled carbon monoxide combines with red blood cells and red blood cells, and the combination will squeeze out the ability of red blood cells to transport oxygen. Under normal circumstances, people live on oxygen, but after gas poisoning, the oxygen in the body is replaced by carbon monoxide, and then there will be hypoxia. The brain is most in need of oxygen. The symptoms of gas poisoning are manifestations of the nervous system. Mild symptoms such as dizziness, headache, nausea, vomiting, lethargy, and severe coma are related to hypoxia in the brain. The binding capacity of carbon monoxide and red blood cells is stronger than that of oxygen. Put patients with gas poisoning into fresh air. Since the oxygen content in the atmosphere is only 1/5 of the air, the excretion of gas poisoning takes 10-20 hours. After the gas-poisoned patient is put into the hyperbaric oxygen chamber, the amount of oxygen inhaled by the patient is far greater than the oxygen content in the air. Many severe patients wake up before the treatment is over, and the symptoms of poisoning can be seen after 40-50 minutes Be relieved.
Treatment of cerebral thrombosis
The advantage of entering the hyperbaric oxygen chamber is that blood is supplied from the surrounding normal brain tissue to the lesion area. Blood inverted and reversed blood phenomenon: After giving patients with cerebral thrombosis a blood vessel dilation medicine, normal brain tissue cells respond sensitively to the drug, but the response of the lesion area is not very sensitive, and the blood vessels are not expanded. The blood of the brain is also from normal brain tissue. The phenomenon of flowing through the expanded area without passing through the diseased area is called bleeding. Hyperbaric oxygen therapy can reverse the blood.
Safety care of hyperbaric oxygen chamber
Points of preparation before entering the cabin
1: All patients who require hyperbaric oxygen therapy must be checked by a hyperbaric oxygen specialist before treatment, and they can enter the cabin for treatment after confirming that there are no contraindications. Second: do a good job in missionary work, teach patients to do inflating and pressure adjustment, prevent earaches from affecting the pressure during the compression process, and enable patients to actively cooperate with the cabin treatment. Third: Educate patients and escorts that it is strictly forbidden to bring fire, fire sources, flammable, explosive, volatile items and electric and electronic toys into the cabin to prevent fire. Explain that bringing the watch into the cabin can easily cause mechanical damage or inaccurate travel time, and the pen can easily cause ink spillage. Fourth: As the cabin takes a long time (approximately 2 hours), instruct the patient and escort to empty their bowels before entering the cabin. It is not advisable to eat too full or gassy foods, such as milk, soy milk, potatoes, radishes, leeks, etc. . Fifth: Equipped with lockers and dedicated oxygen supplies. Assist patients to properly keep and store treatment items, and distribute patient gowns and locker keys to facilitate item turnover and management. Sixth: Instruct patients to contact doctors and nurses in time when they have special circumstances, and enter the cabin after diagnosis and treatment. When you have a cold, you can rest for a few days and enter the cabin after the symptoms are relieved, otherwise the Eustachian tube cannot be opened, which will affect the pressure regulation and cause earache. Seventh: Check vital signs of critically ill patients in the air pressurized cabin before entering the cabin. Fix and debug various catheters and keep them unobstructed, prepare rescue equipment and items, connect the oxygen tube and exhalation tube for the patient, check and adjust the oxygen resistance in time. Critically ill, comatose rescue, oxygen inhalation from a ventilator in the cabin, infusion or tracheotomy in the cabin, patients who need medical care in the cabin, the elderly and infirm, children, and those with relative contraindications to hyperbaric oxygen, cannot take care of themselves In order to prevent accidents, patients with restlessness, flat cars, wheelchairs entering the cabin and other special circumstances must be accompanied by medical staff and their family members. Eighth: Personnel entering the pure oxygen cabin must take off their underwear, and replace the body with the pure cotton underwear provided by the undergraduate, covering the pure cotton bedding provided by the undergraduate. The patient’s own clothes are not allowed into the cabin. Children can carry a piece of pure cotton. Cotton (paper) diapers, bring a milk (water) bottle into the cabin. No other items are allowed. All personnel entering the pure oxygen cabin must wear cotton work caps to cover all hair. Combing hair and other actions that may cause static electricity are strictly prohibited in the cabin ; Strictly grasp the indications, critically ill, agitated patients should not enter the pure oxygen chamber for treatment. The cabin crew strictly grasps the treatment plan, observes the patient’s condition changes through the observation window at any time, and reports the abnormality in time for timely treatment.
Key points of safety care during in-cabin treatment
After the door is closed, ask the patient to concentrate and follow the instructions of the cabin crew. During the pressurization process, adjust the pressure and blow air. If earache occurs, notify the operator in time, slow down or suspend the pressurization, so as not to cause middle ear barotrauma, and continue pressurization after the pressure adjustment is adjusted. Individuals who fail to regulate pressure can take the patient out of the transition chamber for atmospheric oxygen inhalation. Second: It is best to breathe through the nose when inhaling oxygen to warm and humidify the inhaled gas; at the same time, maintain a normal breathing rate. Third: Care for patients in the air pressurized cabin: After the pressure reaches the treatment pressure, follow the instructions of the cabin operator and wear a mask to inhale oxygen; it is best to use an open bottle for the infusion patients in the cabin, because the water level in the Murphy’s tube rises when pressurizing You can’t see the instillation situation clearly, so pay attention to the adjustment of the level; to prevent oxygen poisoning, rest 10 minutes between two oxygen inhalations; you can read newspapers, magazines or listen to the music played on the console during oxygen inhalation; Do a good job of monitoring the heart rate, blood pressure and respiration in the critically ill patient’s cabin, adjust the infusion rate, check whether the catheters are in place, and keep breathing smooth. Fourth: Care of patients in the pure oxygen chamber: the child should be placed on his side and facing the observation window for observation; to ensure safety, friction should be reduced; the cabin crew should operate in strict accordance with the regulations, strictly control the treatment plan, and pay attention to the temperature in the cabin , Regular ventilation after stabilization.
Key points of safety care during decompression
During the decompression process, do not rely on any part of the body on the metal bulkhead, do not move or hold your breath in large amounts, so as not to affect blood circulation and prevent induction of decompression sickness and barotrauma. Second: During the decompression process, when the cabin temperature drops and reaches the dew point, mist will appear in the cabin, and the patient should not be panicked. This is a normal phenomenon, and the mist will disappear after ventilation. The temperature during decompression can be lowered by 2~3 ℃ than that during constant pressure. The patient must keep warm. Third: Air pressurized cabin: After the patient finishes inhaling oxygen, remove the mask to stop oxygen inhalation. Due to changes in gas volume and pressure during decompression, the level of the Murphy’s tube drops in patients undergoing infusion. The level should be adjusted in time to prevent air from entering the blood vessels. During the whole process of treatment in the cabin, pay attention to the hygiene in the cabin, do not throw away peels, spit, and keep the cabin clean.
Key points of safety care after leaving the cabin
As the gas density increases under high pressure conditions, the respiratory resistance increases, the endocrine level increases, and the body’s metabolism is vigorous. Therefore, some people will feel tired after the treatment, and the symptoms can be relieved after the patient is asked to take a hot bath or rest. Second: Due to improper pressure regulation, some patients still feel uncomfortable in their ears after exiting the cabin. Explain to the patients that there is no need for treatment in general and the symptoms can be relieved by themselves. Individual patients who feel unwell can leave after being checked by a doctor. Third: the treatment of oxygen chamber equipment after exiting the cabin. Supervise and assist hygienists in cleaning, disinfecting, and ventilating the oxygen chamber to prevent cross-infection, bacterial culture and monitoring the intensity of ultraviolet light once a month. Check the oxygen chamber equipment and keep it in good condition.
Whether the operation complies with the regulations
Secondly, whether the operation of medical staff complies with the regulations is also a cause of the explosion. Due to the special nature of hyperbaric oxygen chamber treatment, local health departments should certify the hospitals that introduced the equipment, and conduct induction training for the operators and obtain qualification certificates. Generally, hospitals have strict regulations on the operation of hyperbaric oxygen chambers.
Patient Code of Conduct
Whether the patient’s behavior is standardized is also the main reason for the explosion. The movement and friction of personnel in the cabin may generate thousands or even tens of thousands of volts of static electricity. The collision of seats or treatment beds may generate sparks and provide the minimum ignition energy. If the conditions are suitable, it will cause burning. Form a fire. There are very strict regulations when entering the hyperbaric oxygen chamber for treatment. Patients must undergo strict inspections by the doctor and must change their clothes and shoes. According to the requirements, patients must wear cotton clothes when entering the hyperbaric oxygen chamber, and they must not carry any metal objects on their bodies. Generate static electricity to cause a fire. Wet your hair, because the gel and water on your hair may cause friction and static electricity to catch fire. It is also not allowed to carry matches, lighters, stoves, MP4, mobile phones, children’s toys, pens, oil pens, etc. Something that sparks static electricity. In addition, the aging of the wiring in the cabin may also cause fire and explosion. Special clothing products for hyperbaric oxygen chamber
