PROBLEM TO BE SOLVED: To estimate how much quantity of an anesthetic is accumulated in a patient's body at a certain point and how the accumulated quantity in the body changes in what minute depending on how the concentration of the anesthetic to be supplied is varied. SOLUTION: Incoming and outgoing balance of the anesthetic is operated in an operating section 14 based on detected values by anesthetic gas sensors 43a, 43b provided respectively in mixing chambers 26 and 28 and a flow rate sensor 37. The operated values of the balance obtained in this way is integrated in a patient simulator 53 to calculate the quantity of the anesthetic of the patient's body and the distribution state of the quantity of the anesthetic in a plurality compartments separated in the patient's body is calculated, and the result is displayed on a displaying section 15.
