The item was donated by Dr K McCaul of the Royal Women's Hospital, Melbourne, in 1966.Anaesthetic trilene was administered to the patient via rubber tubing from the Trilene inhaler, within which the anaesthetic was converted into a vapor. The cylindrical metal apparatus sits atop a flat, square stand with four black rubber feet. Item includes ports and valves for connection to a face mask and vaporising chamber, as well as mask attachment and metal pouring jug with spout.Red markings identifying the manufacturer and the measurement scale are located on both the stand and top twist dial. The base of the mask attachment piece is inscribed with the manufacturer's details: 'Cyprane Ltd'. The metal beaker is engraved with a line marked at the 15cc level. trilene inhaler, tecota, anaesthesia, beaker, mask, vaporise, obstetrics, childbirth, dr k mccaul royal women's hospital melbourne, 1966, vapor, face mask, vaporising chamber, cyprane ltd, keighley

The Epstein, Macintosh, Oxford vaporizer (EMO) was designed in 1952 by Dr H. G. Epstein and Sir Robert Macintosh of the Nuffield Department of Anaesthetics at the University of Oxford, with the aid of their technician, Mr Richard Salt. It was essentially a refinement of their earlier Oxford vaporizer and designed specifically to deliver ether in known concentrations, irrespective of the temperature of the ether. Robert Macintosh was born at Timaru New Zealand in 1897. In December 1915 he travelled to Britain and was commissioned in the Royal Scots Fusiliers, soon transferring to the Royal Flying Corps. He was shot down behind enemy lines on 26 May 1917 and taken prisoner, escaping several times. When the war ended he returned to medical school and qualified in 1924 as MRCS LRCP. Macintosh's initial intention was to be a surgeon, but soon after qualifying he developed an interest in the field of anaesthesia. Macintosh became the first professor of anaesthetics at Oxford although the university was at first against the appointment. He recruited the scientists Dr Kurt Mendelssohn and Dr H G Epstein and together they designed and built the Oxford vaporiser, a simple, portable, and accurate means of delivering varying concentrations of ether which was to see service in the second world war. He was knighted in 1955 and died at Oxford in 1989.The apparatus is a round, barrel style object with three small rubber feet and a moulded handle over the top. It consists of a vaporising chamber, wick, ether level indicator, temperature compensating value, air bypass chamber and mixing chamber.

Used by mothers during childbirth, the anaesthetic Trilene (trichloroethylene) was inhaled through a face mask [missing] attached to the rubber tubing [missing] and the vaporising chamber. The Trilene was poured into the chamber to be turned into a vapour. The machine was used in the obstetric wards at University College Hospital, London. Trilene was introduced in the 1940s. The machine was made by Cyprane Ltd.Khaki metal multi layered cylinder.

The Fluotec vaporizer was made to administer only halothane (Fluothane). It was one of the first vaporizers made for use with only one anesthetic, and one of the first to use a bimetallic coil for temperature compensation.The bimetallic coil is part of the valve that controls how much of the carrier gas enters the vapor chamber to vaporize the anesthetic.Modern vaporisers still use this bimetallic coil technology today. Serial No: 5040 Patent No: 814427 A ready reference “calibration card” came attached to these vaporizers. The card was printed with a scale that indicated the concentration of halothane produced at different flow rates and dial settings.This item does not have a reference card with it.This Flotec vaporiser holds historic significance as a very good example of an early model piece of equipment for halothane only administration. Modern vaporisers still use the bimetallic coil technology and therefore this object has scientific and research significance.Small metal stand with 3 rubber feet, Main metal cylinder body housing the bimetallic coil. Inlet valve with a brass attachment and metal outlet valve. Metal dial that controls % Penthrane. Dial notches range from OFF to 1.5. Small silver chain hangs from the top of the dial lever.
