Abstract
An apparatus is disclosed for admixing anesthetic with respiratory gas to be supplied to a patient, which comprises a mixing chamber having an inlet for receiving the liquid anesthesia and the respiratory gas, and an outlet for supplying the mixture. A feed line is provided in the inlet for the liquid anesthesia, with a heat exchanger for equalizing the inlet temperatures of the anesthesia and respiratory gas. Temperature sensors are provided in the inlet and the outlets with a circuit for determining the difference between the temperatures. Without heating of the chamber this difference is proportional to a ratio between the evaporated anesthetic and respiratory gas. With the chamber heated to equate the inlet and outlet temperatures, the amount of heating is proportional to the flow of anesthetic to the chamber.
