Currently, inhalation anesthesia is the mainstream animal anesthesia internationally. Compared with the traditional anesthesia, the inhalation anesthesia has the advantages of rapid induction awakening, strong controllability of anesthesia concentration, low in vivo metabolic rate, few side effects and the like. Therefore, the method is easy to control in animal experiments or surgical operations, and can effectively reduce the death rate of anesthetized animals. An anesthetic gas purification device is indispensable for inhalation anesthesia. The device may be omitted during short duration surgical procedures, but over twenty minutes, or in a laboratory with a small space, and the anesthetic-inducing off-gases must be absorbed before they can be vented to the laboratory atmosphere. The international method is to use a tail gas absorption tank F/AI R filled with activated carbon particles, wherein the residual anesthetic gas in the tail gas is absorbed by the activated carbon and then discharged through a discharge port. In the process of gas anesthesia of small animals, the non-circulation mode usually adopted can lead to the overflow of anesthetic gases (such as isoflurane, sevoflurane and the like), the gas recoverer provides a negative pressure environment, waste gas discharged by the anesthetic mask can be discharged after being absorbed by the gas filtering tank, a safe operating environment is provided, and operators are protected to the maximum extent.
