Valve surgery operating room decontamination tank is an indispensable component of medical gas system installation, as the main operating room medical gas supply source terminal equipment. 1, various gas gauges to monitor in real time; 2, can be equipped with oxygen, attract, air, nitrous oxide, exhaust gas recycling terminal; 3, the terminal has a fast automatic sealing function, easy to use and quick; medical oxygen system works: Variable pressure adsorption oxygen machine is used as adsorbent zeolite 5A. 5A zeolite crystals are cage-type structure, a very well-developed crystal cave. Has a very strong cation and anion in the crystal oxygen hole constituting a polarity strong polar molecular sieves, and oxygen and nitrogen are non-polar molecules medical gas system, when the polarity of oxygen and nitrogen through 5A molecular sieves, in a polar molecule the role of medical gas equipment, oxygen and nitrogen produced induced dipole, and oxygen and nitrogen polar dipole induced dipole and 5A zeolite produces a force induction, induced polarization force easily produce far greater nitrogen resulting in oxygen-induced force, therefore 5A zeolite for nitrogen adsorption capacity greater than for oxygen adsorption capacity of medical gases, so nitrogen is preferentially adsorbed and 5A zeolite molecular sieve solid phase enriched in oxygen enriched in non-solid phase This is the oxygen product gas. 5A molecular sieve also has a pressurized nitrogen adsorption capacity increases, when the pressure to reduce the adsorption capacity characteristics. So, when 5A zeolite can be used on pressurized nitrogen adsorption, decompression, nitrogen desorption from 5A molecular sieve out ways to achieve PSA oxygen.
