Abstract
1511226 Anaesthetic apparatus NATIONAL RESEARCH DEVELOPMENT CORP 24 April 1975 [25 Jan 1974] 03596/74 Heading A5T [Also in Division F2] A valve for anaesthetic apparatus which shuts off the anaesthetic supply if the oxygen supply fails and permits the patient to breathe atmospheric air comprises a plunger 5 which is urged to open the supply conduit 1, 2 in response to pressure of the oxygen component of the anaesthetic mixture applied to a piston head 19 of the plunger 5, the plunger 5 being biassed to close the conduit 1, 2 by a spring 6 and being formed with an aperture 17 which connects the outlet end 2 of the conduit to atmosphere by way of a vent and a whistle 14 when the conduit is closed. The plunger also has a groove 16 which connects the inlet end 1 of the conduit to atmosphere by way of a whistle 13 when the conduit is closed, thus providing a vent for anaesthetic gas.
