APPARATUS AND METHOD OF ANAESTHETISING GAS TREATMENT Russian patent published in 2011 - IPC A61M16/01 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to anaesthetising gas treatment. Proposed apparatus comprises first chamber with intercommunicated inlet and outlet, the former being communicated with anaesthetising apparatus exhaust and arranged to receive gas flow containing waste anaesthetising gas components. First outlet valve has first end communicated with chamber outlet and second end for communication with vacuum collector. Outlet valve serves to carry out selective disconnection of first chamber from vacuum collector. First detector control flow entry into first chamber. Said first detector is connected with outlet valve to control the latter. When waste anaesthetising gas wastes stay in first chamber, first detector caused first outlet valve opening to communicate first chamber outlet with vacuum collector to evacuate gas flow containing waste anaesthetising gas components from first chamber into vacuum collector. Invention covers also method of entrapping said components, methods of withdrawing and separating gas components from gas mix, and systems intended for preventing discharge of anaesthetising gas into atmosphere.

EFFECT: higher efficiency, preventing discharge of anaesthetising gas into atmosphere.
