Abstract
A safety system is provided for anesthetic systems with at least two anesthetic vaporizers, the safety system preventing the simultaneous supply of anesthetic to a breathing circuit by more than one anesthetic vaporizer. The safety system which prevents this includes a setting means for each vaporizer which emits an activation signal when moved from an OFF position to an active position. The activation signal is received by a control unit which then sends a control signal to blocking valves, respectively arranged by the anesthetic vaporizers, and prevents the passage of breathing gas to more than one anesthetic vaporizer for vaporization of an anesthetic.
