Abstract
A filling device for anesthetic vaporizers, with a connection piece which can be connected to a connection opening of an anesthetic reservoir in a gas-tight and liquid-tight manner. Leakage of anesthetic gas or liquid anesthetic can be avoided during the filling especially of low-boiling anesthetics by providing the reservoir 10 with a seal 17, which closes the connection opening 9 at least in a liquid-tight manner and can be opened by a projection 5 which is arranged on the connection piece 2 and extends into the interior space of the connection opening 9, as soon as the connection piece 2 is sealed off from the surroundings against the connection opening 9 by a sealing element 15 in a gas-tight and liquid-tight manner.
