DEVICE FOR SUPPORTING SAFE GAS PRESSURE WITHIN GIVEN LIMITS Russian patent published in 2006 - IPC A61M1/16 

FIELD: medical engineering.

SUBSTANCE: device has the first canal having gas-impermeable membrane as wall part. Reservoir communicates with the first canal and is intended for storing oxygen. The first inlet opening serves for introducing anesthesia gas directly into the first canal. The reservoir allows oxygen to flow into the first canal from the reservoir when the first canal pressure is lower than in comparison to the ambient medium pressure.

EFFECT: reduced respiratory gas overhead.
