Filling device for an anesthetic evaporator

A process for filling an anesthetic evaporator with an anesthetic bottle via a filling device at the anesthetic evaporator, the process comprising the steps of:

• inserting a connection device of the anesthetic bottle into a mounting hole at the filling device to open a filling valve at the filling device;
• introducing anesthetic from the anesthetic bottle into the anesthetic evaporator via a fluid channel at the filling device with an anesthetic tank of the anesthetic evaporator and the anesthetic bottle connected with one another during the filling operation in the form of communicating vessels;
• closing the fluid channel by the liquid level in the anesthetic tank reaching a predetermined level;
• and
• providing a vent hole above the fluid channel, which can be opened as needed and with which an additional volume of liquid, which is above the liquid level of the fluid channel, is filled into the anesthetic tank.

An anesthetic evaporator filling system, comprising:

• an anesthetic supply bottle with a connection device;
• an anesthetic tank with structure defining a fluid channel that can be closed by the liquid level of the anesthetic in the anesthetic tank and a vent hole, said vent hole being located at a level above the fluid channel;
• a filling valve opened by the connection of said anesthetic bottle and said anesthetic tank of the anesthetic evaporator with one another during a filling operation to provide communicating vessels wherein anesthetic in the anesthetic supply bottle flows into the anesthetic tank via said fluid channel;
• and
• a vent valve which assumes an open vent hole position or a closed vent hole position, said vent valve being actuated via the filling valve to switch into an open position immediately after the filling operation and being switched into the closed position during the filling operation.
