Technical Field

[0001] This invention relates to the field of anesthetic waste gas treatment technology, and in particular to an anesthetic waste gas treatment device for anesthesiologists. Background Technology

[0002] During surgery, anesthesiologists administer anesthetic gases to patients before surgery. These gases are delivered to the patient's lungs through the mask via the anesthesia machine's inlet tube, through the patient's mouth and nose. However, patients cannot absorb all the delivered anesthetic gases. The unabsorbed gases mix with the patient's own respiration to form anesthetic waste gas, which can easily diffuse into the operating room, posing a threat to the health of medical staff.

[0003] Existing waste gas treatment devices use open absorption, which still allows anesthetic waste gas to diffuse into the operating room, affecting the doctors there. Furthermore, the filtration system is limited to a single type and cannot filter and purify various types of anesthetic waste gas. Summary of the Invention
