How is central diffusion oxygen supply realized?

Hello, do you know the oxygen supply system project of the hospital medical center? Oxygen is generated by molecular sieve oxygen production system, and then distributed to all beds through medical gas pipeline engineering, and oxygen is provided to patients through equipment belts and oxygen inhalation terminals.

Central diffusion oxygen supply is similar to medical central oxygen supply system engineering, such as molecular sieve oxygen supply system and medical gas pipeline engineering. The difference is that the oxygen end is different. The diffused oxygen end is not a medical oxygen mask, but a diffused oxygen end, as shown in the following figure:

By diffusing the oxygen end, the gas with high oxygen concentration obtained by oxygen production mechanism is injected into a relatively closed room, which forms an artificial oxygen-enriched environment to a certain extent, increases the oxygen partial pressure of the gas inhaled by indoor personnel, and improves the anoxic reaction.
