Abstract
An arrangement in an anesthesia vaporizer comprising a liquid container including a vapor generator; a filling device; and conduits for supplying anesthetic from a transport and storage container to the liquid container and/or for removing anesthetic from the liquid container, and for conveying an amount of replenishment gas corresponding to the amount of anesthetic liquid from the liquid container to the transport and storage container upon filling the container and/or inversely upon emptying. For improved operating safety, the filling device is provided with a closing means, adapted to close a filling conduit which opens to the inside of the liquid container and a replenishment gas conduit between the liquid container and the transport and storage container through an overpressure generated in the transport and storage container, and thus prevent anesthetic liquid from flowing to the liquid container.
