Abstract

1294307 Anaesthetic filters MICROFLOW Ltd 25 March 1970 [31 Dec 1968] 61993/68 Heading A5T A filter for air exhaled by an anaesthetised person comprises a heat-insulating jacket enclosing a gas-impervious box which contains a filter element which may be pleated and has inlet and outlet unions which pass through the jacket, and an electric heating element either embedded in the filter or mounted within the heat insulating jacket. An alarm may be incorporated in the electric circuit to give warning of failure in the circuit.
