Abstract
An arrangement in connection with an anaesthetic vaporizer, said arrangement comprising a filling head to be connected to a liquid container of the anaesthetic vaporizer, said filling head being provided with a connection point for an anaesthetic supply container or the like. The filling head comprises a filling conduit adapted to form a flow connection between the connection point for an anaesthetic supply container or the like and the liquid container of the anaesthetic vaporizer for filling the liquid container with an anaesthetic, and a discharge conduit adapted to form a passage through which the anaesthetic in the liquid container of the anaesthetic vaporizer can be discharged to an anaesthetic supply container or the like. To prevent erroneous filling, the discharge conduit is adapted to form a flow connection between the liquid container and the connection point provided in the filling head for an anaesthetic supply container or the like, and the discharge conduit is provided with a separate cut-off device arranged to close the flow connection formed by the discharge conduit.
