[0002] Medical liquid oxygen stations are important facilities in hospitals for storing and supplying liquid oxygen. Their design and operation must comply with specific safety and hygiene standards. In the medical field, most of the main oxygen used in central oxygen supply systems is supplied by liquid oxygen stations. Liquid oxygen storage tanks supply oxygen directly, which has a high pressure and cannot be used directly. It must be vaporized and decompressed before it can be used.

[0003] After the liquid oxygen in the medical liquid oxygen station is vaporized, it is generally decompressed through a decompression device, and then oxygen is supplied through pipelines.
