An anesthetic apparatus has a dosing unit for an anesthetic agent, the dosing unit having a number of containers, each holding a liquid anesthetic agent. The containers are connected by liquid lines to a valve unit, capable of selectively connecting one container at a time to a micropump which dispenses anesthetic in the form of liquid droplets directly to a connection piece in the anesthetic apparatus, to which a patient can be connected. A control unit controls the micropump and the valve unit and regulates both the selection and dispensing of liquid anesthetic.
