The principle of medical center oxygen system is called medical molecular sieve pressure swing adsorption PSA oxygen system, is a molecular sieve (molecular sieve) as the adsorbent, through the pressure swing adsorption (PSA) to the ambient air as the raw material, in the condition of room temperature and low pressure, the use of molecular sieve pressurized nitrogen (adsorbent) adsorption capacity increases, and decompression of nitrogen adsorption capacity decreases, the characteristic of the air, the molecular sieve adsorption capacity increases. Adsorption of nitrogen in the air (adsorbent) when the molecular sieve is pressurized to increase the adsorption capacity, decompression of nitrogen in the air when the adsorption capacity decreases the characteristics of the formation of pressurized adsorption, decompression desorption of the rapid cycle of the process, so that the oxygen and nitrogen in the air can be separated, and the air of carbon dioxide, gaseous acids and other gaseous oxides, etc., all belong to the molecular polarity of the material is very strong, it is difficult to pass through the molecular sieve, so as to make the output of the output of the oxygen of the oxygen purity of more than 93% v/v). .
Because the medical center oxygen system takes the air as the principle, so generally only need to have air can produce oxygen! At present, most of the oxygen generators used in hospitals are Terry's medical central oxygen system, which is safe, convenient, economical and other significant features to obtain the favor of many hospitals!
Is a medical oxygen system safe?There is no right to say that safety, but for us to do experiments in manufacturing oxygen, safety is heaven and earth
What is the principle of the medical center oxygen generator?Working principle: 5A zeolite molecular sieve is used as the adsorbent, 5A zeolite molecular sieve crystal is a cage structure, there are very developed crystal cavities in the crystal cavities have a very strong cation and oxygen negative ions, which constitutes a polar molecular sieve with strong polarity, and oxygen and nitrogen are non-polar molecules, when oxygen and nitrogen are passed through the 5A zeolite molecular sieve, under the action of polar molecules, the oxygen and nitrogen produce an induced dipole, and the induction dipole and 5A induced dipole and 5A induced dipole and 5A induced dipole and 5A induced dipole and 5A induced dipole. Dipole and 5A zeolite molecular sieve polarity dipole action produces a kind of induced force, and easily polarized nitrogen produces induced force is much larger than the induced force produced by oxygen, so 5A molecular sieve adsorption capacity of nitrogen is larger than the adsorption capacity of oxygen, so nitrogen is preferentially adsorbed by 5A zeolite molecular sieve and enriched molecular sieve in the solid phase, oxygen is enriched in the non-solid phase, which is the product of the oxygen gas.
The molecular sieve also has the adsorption capacity of nitrogen increases when pressurized, and the adsorption capacity decreases when the oxygen generator is depressurized. Therefore, the 5A zeolite molecular sieve can be used for 5A zeolite molecular sieve adsorption of nitrogen when pressurized, decompression, nitrogen from the 5A molecular sieve desorption out of the method to realize the variable pressure adsorption of oxygen production.
How does a medical oxygen concentrator produce oxygen?Currently most medical oxygen concentrators use PSA (Pressure Swing Adsorption) air separation technology, which is based on the attractant (zeolite molecular sieve) on the air of oxygen and nitrogen adsorption capacity differences to realize the separation of oxygen and nitrogen. When the air enters the bed equipped with the adsorbent, the nitrogen adsorption capacity is stronger to be adsorbed, while the oxygen is not adsorbed, so that a high concentration of oxygen can be obtained at the exit end of the adsorbent bed. Because the adsorbent has its adsorption amount with the pressure change characteristics, change its pressure, can make the adsorption alternately adsorption and desorption operation.
Which manufacturer has the best price/performance ratio for central oxygen systems?According to my understanding of the highest cost-effective manufacturer is not Hunan Terra Medical Technology, they are using molecular sieve separation air oxygen, and is the use of the United States UOP, France CECA (two molecular sieve giants), the air compressor is the world's first brand of Atlas. I have cooperated with them, so I have a certain understanding of their company, and their company attaches the most importance to quality and service. The company's bosses are all born in the sale of medical equipment, although the company has not been established for a long time, but all the company's bosses are born in the sale of medical equipment, with decades of experience. The price is also absolutely moderate, I have signed their general agent, but also hope that they can do better and better.
Medical center oxygen equipment brand ranking
At present, the oxygen industry is not much brand ranking, technology is similar, many oxygen manufacturers are because of the customer price of how much the configuration of the components, and some even to the second best! As far as I know, the real rules in the middle of doing the "new cloud medical engineering" is good, not because of the low price to accommodate customers, smash their own brand!

What is the principle of medical oxygen generator?The principle of oxygen generator is called medical molecular sieve pressure swing adsorption PSA oxygen system, is a molecular sieve (molecular sieve) as the adsorbent, through the pressure swing adsorption method (pressure swing adsorption, PSA) to ambient air as the raw material, in the conditions of room temperature and low pressure, the use of molecular sieve pressurized air nitrogen (adsorption) Adsorption capacity increase, decompression of nitrogen in the air when the adsorption capacity decreases the characteristics of the formation of pressurized adsorption, decompression desorption of the rapid cycle of the process, so that the oxygen and nitrogen in the air can be separated, and the air carbon dioxide, gaseous acids and other gaseous oxides, etc., are molecules belonging to the polarity of the material, it is difficult to pass through the molecular sieve, so as to make the output of the oxygen of the oxygen purity of 93% v/v or more).
Because the medical oxygen concentrator takes the air as the principle, so generally only need to have the air where the oxygen can be produced! At present, most of the oxygen generators used in hospitals are Terry's medical oxygen generators, which are safe, convenient, economical and other notable features to gain the favor of many hospitals!
What is the difference between central oxygen supply and central oxygen production?The center oxygen is through the air to remove the nitrogen refinery is oxygen.
The center of the oxygen is negative pressure attraction, with paging systems and related facilities, such as the composition of the medical gas supply system
Such as the Terra company made a metaphor is very graphic, as if the tap water, tap water is the center of the oxygen, through the pipeline is the oxygen supply of each room.
What is the principle of medical oxygen generator oxygen? 0 pointsCurrently the principle of medical oxygen generator oxygen is the principle of variable pressure adsorption. The chemical oxygen is not within the scope of medical use. The reason for this is the fact that oxygen is essential to human life. There is no such thing as dependence.
