Abstract
An inhalation mask, an artificial nose unit, an anesthetic gas concentration detector, an extension tube, an anesthesia attachment, and an elastic bag are in communicative connection in sequence. The elastic bag has a mixing chamber formed therein and has an anesthetic inlet, an air inlet, and an outlet port each formed at the boundary to the exterior. The anesthesia attachment includes a hollow structure and an evaporation injector syringe. The outlet port of the elastic bag is in communicative connection with the hollow structure through its opening, and the evaporation injector syringe tightly mates with the interior of another opening. The anesthetic introduced into the mixing chamber is vaporized and then mixed with air introduced from the air inlet into mixed gas. The mixed gas is supplied from the outlet port to the inhalation mask by compressing the elastic bag or other procedures.
