1, oxygen-rich membrane oxygen generator
Oxygen-rich membrane oxygen generator this oxygen generator using the membrane oxygen, through the membrane of nitrogen molecules in the air filtration, to achieve the export of oxygen concentration of 30%, with a small volume, small power consumption and other advantages. However, the machine using this oxygen production method is 30% of the concentration of oxygen, can be used for long-term oxygen therapy health care, and severe hypoxia in the state of the required first aid can only be used to medical high concentration of oxygen.
2, molecular sieve oxygen generator
Molecular sieve oxygen generator is an advanced gas separation technology, physical methods (PSA method) directly from the air to extract oxygen, that is, that is, fresh and natural, the maximum oxygen pressure of 0.2 ~ 0.3MPa (i.e., 2 ~ 3 kg), there is no high-pressure explosive and other dangers.
3, chemical oxygen generator
Chemical oxygen generator is the use of reasonable pharmaceutical formulations, used in specific occasions. Indeed, it can satisfy the urgent need of some consumers. However, due to the equipment is simple, the operation is troublesome, the use of high cost, each time the oxygen need to invest a certain amount of money, can not be used continuously and many other defects, is not applicable to the family oxygen therapy.
4, electronic oxygen generator
Electronic oxygen generator in the drugstore is more common, the use of oxygen in the air in the solution of oxidation and reduction of precipitation process, and thus will not be like electrolysis of water oxygen as dangerous hydrogen.
But this kind of products in the handling and use of the process requirements are very strict, never allowed to tilt and inverted, otherwise the solution will flow into the oxygen tube into the nasal cavity, the user caused serious damage.
At the same time, the use of oxygen production process is prone to produce other oxides, the production of oxygen containing chemicals, such oxygen production method of power consumption, in the use of the process must ensure that the solution has the right concentration, otherwise it can not be normal out of the oxygen, so the choice of the electronic oxygen concentrator consumers must do a good job of maintenance.
Which cases need to use medical oxygenator
1, plateau reaction caused by hypoxia
Plateau environment characterized by low-pressure, hypoxia, plains people into the plateau will generally occur in the respiratory system, the circulatory system, the digestive system, the nervous system of the stress reaction. Oxygen concentrator oxygen therapy can be used for plateau reaction appeared plateau pulmonary edema, acute alpine disease, chronic alpine disease, plateau coma, plateau hypoxia and so on.
2, cardiovascular and cerebrovascular disease
The so-called cardiovascular and cerebrovascular disease is the cardiovascular and cerebrovascular diseases collectively. Including hypertension, heart disease, coronary heart disease, myocardial infarction, cerebral thrombosis, cerebral ischemia, cerebral vertigo, atherosclerosis and so on. These diseases will cause the body to intake of oxygen difficulties, the use of oxygen concentrator oxygen therapy can be timely supplemental oxygen.
3, respiratory diseases
Respiratory diseases is a common and frequent disease, the main lesions in the trachea, bronchial tubes, lungs and thorax, lesions light more cough, chest pain, breathing affected, the heavy respiratory distress, hypoxia, and even respiratory failure and death. Inability to normal intake of oxygen on these diseases is very big, even death, so these diseases patients need an oxygen concentrator for oxygen therapy.
4, other symptoms need oxygen therapy
Weak and sick muscle immunity poor people, heat stroke, gas poisoning, drug poisoning. Such as gas poisoning is the use of coal stoves in the closed room heating, cooking, the use of gas water heaters for a long time to take a bath and ventilation is not smooth, easy to gas poisoning accidents. Oxygen supply after gas poisoning is very important, because the higher the concentration of inhaled oxygen, the higher the partial pressure of oxygen, the faster the separation of carbon monoxide in the blood, the more discharged.
Precautions for the use of oxygen concentrator
1, the patient who purchased the oxygen concentrator should read the manual carefully before use, and it is best to use it under the guidance of a doctor.
2, the oxygen concentrator should be placed in a smooth, use the oxygen concentrator to avoid open flame, to avoid fire.
3. When the oxygen concentrator is not used for a long time, please cut off the power supply, pour out the water in the humidified bottle, wipe the surface of the oxygen concentrator clean, cover it with a plastic cover, and store it in a dry place without sunlight.
4, with the oxygen generator filling oxygen bag should pay special attention to, oxygen bag filling must first pull out the oxygen bag after the cannula, and then turn off the oxygen generator switch, otherwise it is easy to cause the water of the humidification bottle negative pressure anti-suction into the oxygen generator, resulting in the failure of the oxygen generator.
5, the oxygen concentrator in the transportation and storage process, is strictly prohibited horizontal, inverted, humid or direct sunlight.
