Abstract
A safety filling device for filling a liquid anesthetic into a filling space of an anesthetic evaporator from a storage container by means of a filling adapter, which can be pushed into an insertion opening, with a closing element, which interrupts the flow of liquid anesthetic in a switched-off position, and with a control element, which is movable in a stationary housing and sets the states of switching. A preferential position is set on the closing element during the introduction of the filling adapter into the insertion opening. A follower blocking the switched-off position is provided on the closing element between the housing and the control element, and a coding part, which engages the follower in a manner eliminating the blocking of the closing element in the operating position of the filling adapter, is provided on the filling adapter.
