In a large-scale operation process, general anesthesia is often needed to be carried out on a patient, and anesthetic drugs for realizing the general anesthesia mainly comprise intravenous anesthetic drugs and inhalation anesthetic drugs. The inhalation anesthetic enters the lung of a patient through inhalation of a patient to achieve an anesthetic effect, and in the general anesthesia process, the patient loses the autonomous respiration function, and needs a machine to help the patient to breathe and achieve a continuous anesthetic effect, wherein the machine is called an anesthetic machine. If the gas generated by the patient during expiration during the anesthesia process is directly discharged into the air in the operating room, a small amount of anesthetic gas which is not absorbed by the patient can be more or less inhaled by doctors and nurses in the operating room, and the health of medical staff can be affected in the long term. Therefore, in order to avoid the pollution of the operating room by the waste anesthetic gas generated in the current clinical anesthetic work, the waste anesthetic gas needs to be discharged to the outside of the operating room by using related equipment. The common negative pressure suction system can not be directly connected with the anesthesia machine because the exhaust gas of the anesthesia machine is discharged discontinuously, the disposable discharge capacity is large, and the gas suction of the negative pressure suction system is continuous, so that the complete suction of a large amount of instantly grown exhaust gas is difficult. Meanwhile, in the gap of waste gas exhaust of the anesthesia machine, negative pressure is continuously generated on the anesthesia machine by negative pressure suction, the operation of the anesthesia machine can be interfered, the anesthesia effect is seriously influenced, the life safety of a patient is threatened, and serious potential safety hazards exist.
Therefore, how to absorb the waste gas generated by the anesthesia machine as much as possible without affecting the normal operation of the anesthesia machine is a problem to be solved by those skilled in the art.
