An anesthetic applicator with a temperature/moisture regulating capability is provided. The anesthetic applicator includes: means for supplying anesthetic; an inner duct, connected to the anesthetic supplying means, for conducting the anesthetic to the patient; means for recycling the exhaled breath from the patent so that the recycled anesthetic can be resupplied via the inner duct to the patient; an outer duct sleeving the inner duct in such a manner that a passage is formed between the outer duct and the inner duct; and means for supplying a stream of heated fluid such as heated air or water to flow through the passage between the outer duct and the inner duct. The recycling means includes: an exhaled-gas duct connected to receive the exhaled breath from the patient; an exhaling valve connected to the outlet of the exhaled-gas duct; a carbon-dioxide collector for filtering out the carbon dioxide contained in the exhaled breath of the patient; and means for conducting the exhaled gas from the carbon-dioxide collector to the inner duct so that the anesthetic gas can be recycled for use on the patient. This anesthetic applicator is capable of regulating the anesthetic being supplied to the patient within suitable temperature and humidity ranges. This allows the supplied anesthetic gas to adjust to the temperature/humidity conditions inside the patient's body, so that undesirable consequences to the patient can be avoided.
