An interface device for supplying a gas flow for breathing is disclosed herein. The device includes at least one socket for detachably connecting an apparatus for supplying anesthetic agent, at least one gas output opening for delivering the fresh gas to the apparatus, and at least one gas input opening for receiving the fresh gas mixed with anesthetic agent. The device also includes a connection valve and at least four ports in flow communication with the valve, a first port receiving the gas, a second port providing a communication with the output opening, a third port providing a communication with the input opening, and a fourth port providing a communication for breathing, the valve having a first operational state disconnecting communication between the first and second port, and to second operational state providing communication between the first and second port, but also between the third and fourth port.

1. An interface device for supplying a gas flow for subject breathing, said device comprising: at least one socket for detachably connecting an apparatus for supplying anesthetic agent;at least one gas output opening for said at least one socket for delivering fresh gas to said apparatus;at least one gas input opening for said at least one socket for receiving from said apparatus the fresh gas mixed with anesthetic agent to supply further for subject breathing; anda connection valve for said at least one socket and at least four ports in flow communication with said connection valve, a first port receiving the fresh gas guided to said device, a second port providing a gas flow communication with said at least one gas output opening, a third port providing a gas flow communication with said at least one gas input opening, and a fourth port providing a gas flow communication for subject breathing, said connection valve having a first operational state disconnecting a gas flow communication between said first port and said second port and also providing a gas flow communication between said first port and said fourth port, and a second operational state providing a gas flow communication between said first port and said second port and also providing a gas flow communication between said third port and said fourth port. 2. The interface device of claim 1, wherein said connection valve in said first operational state is further configured to disconnect said gas flow communication between said third port and said fourth port. 3. The interface device of claim 1, wherein said connection valve comprises a single valve member configured to move between at least two positions inside a valve cavity to provide said first operational state and second operational state. 4. The interface device of claim 3, wherein said connection valve also comprises a valve spring configured to force said valve member to one of said at least two positions. 5. The interface device of claim 4, wherein said connection valve also comprises a connection valve interface that may receive and transfer a force to force said valve member to another of said at least two positions. 6. The interface device of claim 5, wherein said connection valve interface is in operational contact with said apparatus, wherein the apparatus is configured to force said valve member to said another of said at least two positions when the apparatus is connected to said at least one socket. 7. The interface device of claim 5, wherein said valve spring is in forced position when the apparatus is connected to said at least one socket, whereby said valve member is in said another of said at least two positions. 8. The interface device of claim 3, wherein said connection valve also comprises seals positioned to border said valve cavity, said seals being crosswise to a longitudinal axis of said valve cavity, and said seals being at predetermined distance one after the other along the longitudinal axis of said valve cavity. 9. The interface device of claim 8, wherein said longitudinal axis of said valve member is parallel to said valve cavity, and that said valve member comprises at least three thick sections and at least two thin sections crosswise to said longitudinal axis and which thick and thin sections are configured to occur alternately along the longitudinal axis of said valve member. 10. The interface device of claim 9, wherein said thick sections leaving therebetween thin sections are configured to border at least partly a first cavity and a second cavity inside said valve cavity and which first cavity in the first operational state is configured to connect said first port and said fourth port disconnecting the gas flow to said second port. 11. The interface device of claim 10, wherein said second cavity in the first operational state is configured to disconnect said third port and said fourth port. 12. The interface device of claim 9, wherein said thick sections leaving therebetween thin sections are configured to border at least partly a first cavity and a second cavity inside said valve cavity and which first cavity in the second operational state is configured to connect said first port and said second port. 13. The interface device of claim 12, wherein said second cavity in the second operational state is configured to connect said third port and said fourth port. 14. The interface device of claim 1, wherein said connection valve in said first operational state is configured to connect the gas flow communication between said first port and said fourth port. 15. A method for supplying the gas flow from an interface device for subject breathing, said method comprising:connecting detachably an apparatus for supplying anesthetic agent to at least one socket of said interface device;delivering a fresh gas through at least one gas output opening of said at least one socket to said apparatus;receiving through at least one input opening of said at least one socket from said apparatus the fresh gas mixed with anesthetic agent to provide further for subject breathing; andproviding gas flow communication in said interface device between a connection valve and at least four ports, a first port receiving the fresh gas guided to said device, a second port providing a gas flow communication with said at least one gas output opening, a third port providing a gas flow communication with said at least one gas input opening, and a fourth port providing a gas flow communication for subject breathing, said connection valve having a first operational state disconnecting a gas flow communication between said first port and said second port and also providing a gas flow communication between said first port and said fourth port, and a second operational state providing a gas flow communication between said first port and said second port and also providing a gas flow communication between said third port and said fourth port. 16. The method of claim 15 further comprising disconnecting in said first operational state said gas flow communication between said third port and said fourth port.
