[0002] Anesthetic gas purification refers to the purification of anesthetic gases used in medical environments such as operating rooms and anesthesia rooms to reduce the risk of medical staff and patients being exposed to harmful anesthetic gases. Anesthetic gas purification systems usually include absorption, filtration, purification and discharge, and various technical means are used to remove or reduce harmful components in anesthetic gases to a safe level. When purifying anesthetic gases, gas purification devices are required.
