Sources of medical gases, medical gas central stations
All medical gas systems are unique and differ from each other in every particular medical institution. But it is worth noting that there are common elements in all medical gas systems that fulfill different tasks.
The main element of any system is its source and specific medical gas fittings. The second element is gas pipeline, spread throughout the medical institution, forming the internal network of medical gases.
Sources of medical gases may be different, but as a rule, they include: gear module (ramp) of automatic switching with microprocessor control for autonomous supply with medical gases from the cylinders from oxygen, nitrous oxide and carbon dioxide. The number of cylinders is determined by the number of places where the gas is supplied and by the need in gas supply in general. They include compressor stations in order to provide the supply of compressed air, completely purified and filtered from bacterial and atmospheric pollution. Also they include the system of control over the automatic switching station, which allows adjusting the load between the compressors to maintain their uniform operating hours, automatically turning on and off the compressors at a certain level. Sources also include vacuum stations that provide continuous pumping of air, gases and vapors in continuous operation, and oxygen concentrators with blocks to generate oxygen using separation method. Other sources of medical gases worth mentioning are cryogenic cold gasifiers and bottle batteries medical gas stations used to supply medical gases directly into the gas lines, as well as monitoring of gas supply and transmission of sound and light signal in case of deviations from normal operation.
