An apparatus and method for supplying anesthetic agent to an anesthesia system. The system is connecting detachably with at least two such apparatuses. The apparatus includes a storage volume for a liquid anesthetic agent and a space for evaporating the liquid agent. The apparatus also includes a gas inlet port for receiving a fresh gas for mixing with evaporated agent and a gas outlet port for conducting the gas mixture including evaporated agent to the system. The apparatus also includes a logic circuit for controlling anesthetic agent supply and an apparatus signal connector to exchange information. The apparatus signal connector includes at least one first apparatus contact for receiving from the system a signal indicating whether anesthetic agent supply is allowed or prevented, and a second apparatus contact to indicate that this apparatus is configured to supply anesthetic agent.

1. A system for supplying anesthetic agent to an anesthesia system, the system being configured to connect detachably with at least two apparatuses, the system comprising: an interface device comprising a number of sockets, wherein the number of sockets is at least two, wherein at least one socket of the at least two sockets comprises an interface signal connector; a storage volume for a liquid anesthetic agent;a space for evaporating the liquid anesthetic agent;a gas inlet port for receiving a fresh gas for mixing with evaporated anesthetic agent;a gas outlet port for conducting the gas mixture including evaporated anesthetic agent out to the interface device;a logic circuit for controlling anesthetic agent supply to the anesthesia system; andan apparatus signal connector configured to detachably connect with the anesthesia system to exchange information and configured to mate with the interface device,wherein the apparatus signal connector comprises a number of first apparatus contacts configured to receive from the interface device a signal indicating whether anesthetic agent supply to the anesthesia system is allowed or prevented, and a second apparatus contact configured to indicate that this apparatus is configured to supply anesthetic agent to the anesthesia system, andwherein the interface signal connector is configured to mate with the apparatus signal connector. 2. The system of claim 1, wherein the second apparatus contact is configured to transmit an INACTIVE signal to inactivate any other apparatus connected to the anesthesia system. 3. The system of claim 2, wherein the apparatus signal connector also comprises a third apparatus contact to confirm that the INACTIVE signal was properly transmitted to the anesthesia system. 4. The system of claim 1, wherein each socket is configured to detachably connect one of the at least two apparatuses to the anesthesia system. 5. The system of claim 1, wherein the signal indicating whether anesthetic agent supply to the anesthesia system is allowed or prevented is based on an operational state of at least one of the at least two apparatuses connected to the anesthesia system. 6. The system of claim 5, wherein an operational state of at least one of the at least two apparatuses, is one of two options, the first option being whether the at least one of the at least two apparatuses is activated to supply anesthetic agent to the anesthesia system, and the second option being whether the at least one of the at least two apparatus is inactivated from anesthetic agent supply to the anesthesia system. 7. The system of claim 5, further comprising a user interface configured to change the operational state of the at least one of the at least two apparatuses to allow or to prevent mixing the evaporated anesthetic agent to the fresh gas received through the gas inlet port. 8. The system of claim 1, further comprising a user interface configured to provide a signal indicative of a concentration setting for the logic circuit. 9. The system of claim 8, wherein the user interface is configured to adjust anesthetic agent concentration. 10. The system of claim 1, wherein the number of first apparatus contacts is one less than the number of sockets. 11. The system of claim 1, wherein: each socket of the at least two sockets comprises a gas output opening and a gas input opening,wherein the gas output opening is configured to mate with the gas inlet port, andwherein the gas input opening is configured to mate with the gas outlet port. 12. A method for supplying anesthetic agent from at least two apparatuses to an anesthesia system using the system of claim 1, the method comprising: providing a signal communication between a vaporizer, the interface device, and the anesthesia system;activating the vaporizer to supply anesthetic agent to the anesthesia system;receiving in the vaporizer a first signal from the interface device;indicating based on the first signal whether the anesthetic agent supplied to the anesthesia system is allowed or prevented; andtransmitting a second signal from the vaporizer activated to supply the anesthetic agent to the anesthesia system to indicate that the apparatus is configured to supply the anesthetic agent to the anesthesia system. 13. The method of claim 12, further comprising inactivating, based on the second signal, an other apparatus of the at least two apparatuses connected to the anesthesia system to prevent the supply of the anesthetic agent to the anesthesia system. 14. The method of claim 12, wherein whether anesthetic agent supply to the anesthesia system is allowed or prevented is based on an operational state of at least one apparatus of the at least two apparatuses connected to the anesthesia system, when the operational state of the at least one apparatus of the at least two apparatuses is one of two options, the first option being whether the at least one of the at least two apparatuses is activated to supply anesthetic agent to the anesthesia system, and the second option being whether the at least one of the at least two apparatuses is inactivated to prevent anesthetic agent be supplied to the anesthesia system. 15. The method of claim 14, further comprising transmitting a status signal from the interface device to the vaporizer to confirm that the second signal was properly transmitted from the apparatus to the anesthesia system. 16. The system of claim 1, wherein: at least one apparatus of the least two apparatuses is configured to supply the anesthetic agent to the interface device and a vaporizer, the system further comprising:a fresh gas mixer configured to prepare a breathing gas mixture. 17. The system of claim 16, wherein the fresh gas mixer is located upstream of the interface device and the vaporizer. 18. The system of claim 1, wherein the interface signal connector comprises an interface contact configured to transmit a status signal to confirm that an inactive signal to inactivate one of the at least two apparatuses was properly transmitted to the interface signal connector, and wherein the apparatus signal connector further comprises a third apparatus contact configured to receive the status signal to confirm that the interface signal connector received the inactive signal, indicating that the other apparatuses are inactivated to prevent anesthetic agent supply. 19. The system of claim 1, wherein a vaporizer is detachable and remountable to the sockets. 20. The system of claim 1, further comprising: a ventilator configured to assist in the breathing function of a subject;a breathing circuit configured to connect lungs of the subject and the ventilator, the breathing circuit comprising: an inspiration line configured to provide an inspiration gas for the subject breathing;an expiration line to discharge an expiration gas; anda carbon dioxide absorber configured to remove carbon dioxide of the expiration gas.
