In anesthetic systems (2) with at least two anesthetic vaporizers (4, 6, 8), preventing the simultaneous supply of anesthetic to a breathing circuit (10) by more than one anesthetic vaporizer (4, 6, 8) is essential. A safety system which prevents this is described in the invention and comprises a setting means (58, 60, 62) which emits an activation signal when moved from an OFF position to an active position. The activation signal is received by a control device (56) which then sends a control signal to blocking valves (24, 26, 28), arranged by the anesthetic vaporizers (4, 6, 8), and prevents the passage of breathing gas to more than one anesthetic vaporizer (4, 6, 8) for vaporization of an anesthetic. <IMAGE> |
