Abstract
A safety system prevents inadvertent mixing of different anaesthetic agents, during replenishment wherein a new anaesthetic is replenished from a container to an anaesthesia machine containing a flow channel for the delivery of liquid anaesthetic, with a first anaesthetic being present downstream from the flow channel. Inadvertent mixing of different anaesthetics is avoided because the safety system has a measurement unit for identifying the new anaesthetic before the new anaesthetic comes into contact with the first anaesthetic. The measurement unit is arranged upstream from the first anaesthetic.
