Medical standards for compressed air quality

Medical standards for compressed air quality

Medical gas engineering includes: oxygen supply system, vacuum suction system, compressed air supply system, mixed gas supply system, these gas supplies are directly or indirectly in contact with the patient, will bring many hidden problems, so clean compressed air It is very important in medicine.

　　Compressed air is mainly used in various hospitals as follows:

　　1, used for respiratory system and anesthesia system (must ensure clean air);

　　2, as a medium for spray therapy to treat patients with respiratory diseases;

　　3. As a medium for adjusting oxygen concentration such as incubator artificial respirator for premature infants;

　　4. As the power of circulating machines and dental equipment units;

　　 5. Used to blow off dirt and drive dental air drills.

　　 There are three main impurities in compressed air: solid particles, water and oil; other pollutants also include microorganisms and gaseous pollutants.

　　1. Solid particles: It will accelerate the wear of gas-using equipment, cause sealing failure, and easily block the pipeline.

　　2. Moisture: It is the root cause of corrosion of equipment, pipelines and valves. Freezing in winter can also block the small holes in the gas system.

　　3. Oil: The hazard of oil in the air is the greatest. In pneumatic control, a drop of oil can change the condition of the air hole. Sometimes the valve sealing ring and cylinder swell, causing slow operation, serious or even blockage.

　　How to improve the quality of medical compressed air?

　　Medical compressed air must meet the high quality requirements of odorless, tasteless, dry and clean. In order to obtain high-quality air, the gas output by the air compressor must be processed. The first consideration is to remove the more water content in the air. You can use the Betten core dryer and the high-efficiency precision filter to meet the requirements of the hospital Use the required compressed air.
