The apparatus has glass flowmeters and controls for fine and coarse oxygen, cyclopropane, nitrous oxide and carbon dioxide. There is also an ether container and a blood pressure nanometer.•Handwritten in grey pencil on reverse: Dr. Desai's Special Metric •Handwritten in black ink on reverse: III. •Handwritten in grey pencil on reverse: dvpd.anaesthetic equipment, anaesthetic machine, flowmeter, foregger metric gas anaesthesia apparatus, oxygen, nitrous oxide, carbon dioxide, cyclopropane

Black and white photograph of a Boyle's anaesthetic machine. The light-coloured metal frame on castors has a metal top with a flowmeter attached to the top, and there is one drawer at the bottom of the trolley. One side of the trolley has two vaporisers connected to two corrugated tubes with a facemask. An oxygen cylinder and two nitrous oxide cylinders are on the other side of the machine along with a small cyclopropane cylinder.anaesthetic equipment, boyle's machine, anaesthetic machine, nitrous oxide, oxygen, flowmeter

Early cylinders were coloured as their maker saw fit, usually black, perhaps with a white top for oxygen. The Americans first achieved standardisation, but other countries do not follow American Standards. Australia follows the colour-scheme of the British Oxygen Corporation. The body is coloured individually for each gas, viz: compressed air, grey; carbon dioxide, brown; oxygen, black; nitrous oxygen, blue’ cyclopropane, primrose-yellow’ ethylene, mauve. Panels of other colours may appear on the body, but indicate technical points of cylinder-design and do not concern the anaesthetist.

In 1940 doctors started experimenting with curare for use with electric shock therapy. Electric shock therapy regularly caused broken bones, including vertebrae, and all sorts of dislocations. The intensity of convulsions was high and couldn’t be controlled. During the 19th Century curare was unsuccessfully used to treat rabies, tetanus and epilepsy. By 1935, Harold King had isolated tubocurarine, curare’s active ingredient. In 1942, Harold Griffith successfully used standardised curare (Intocostrin) with cyclopropane. Within five years synthesised muscle relaxants were available. Intocostrin, combined with an anaesthetic agent, was a break-through for this treatment.Solid wooden box with three separate sections inside box. First section contains electrical lead for attaching unit to mains power. Second section contains ECT unit and controls. Third sections contains electrical lead ending in plugs for holding in hands. Sections cannot be separated out, they form one unit.Etched on to the face of the internal unit: PROPERTY OF / THE ROYAL WOMEN'S HOSPITAL Label tape affixed to top of the lid: E.C.T. UNIT OP.
