Irregular cylindrical grey inhaler that has been sectioned for teaching purposes. The centre dial is labelled "E.M.O. ETHER INHALER", and controls for the percentage volume of ether released, from "close for transport" to 20%. The sectioned areas of the apparatus have been painted yellow and expose the vaporising chamber, wick, ether level indicator, temperature compensating valve, air bypass chamber and mixing chamber. anaesthesia, vaporizer, vaporiser, sectioned, inhaler

Black and white photograph of a drawing of anaesthetic equipment, a flowmeter and an ether vaporiser. On the right is the ether vaporiser inside a glass cylinder, with a control tap on top of it. It is attached to a metal cylinder which houses the flowmeter which is measuring the Oxygen and Nitrous Oxide. There is a round Oxygen control and a Nitrous Oxide control attached underneath the metal cylinder, as well as an Oxygen Bypass and a Nitrous Oxide Bypass. The diagram has each part of the apparatus named with an arrow pointing to the parts.ether vaporiser, anaesthetic equipment, flowmeter, nitrous oxide, oxygen

The Lidwill machine was designed by Mark Lidwill in 1913, for the purpose of mechanical or insufflation anaesthesia. It was manufactured by Elliott Bros. of Sydney.Colour photograph of a Lidwill anaesthetic machine sitting on carpet.

This gas anaesthesia machine comprises a four yolk manifold, two circular metal components for nitrous oxide and two for oxygen. It is mounted atop a four pointed stand on casters for portability. In addition to reducing valves and regulators, the main stand also supports a cream-coloured, cylindrical Austox fractional rebreather and an ether vaporiser with variable bypass control within a circular glass container. portable, anaesthesia, midwifery, dentistry, obstetrics, oxygen, nitrous oxide, commonwealth industrial gases ltd, cig, austox fractional rebreather, ether vaporiser, variable bypass control, 1950

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.

The Lidwill machine was designed by Mark Lidwill in 1913, for the purpose of mechanical or insufflation anaesthesia. It was manufactured by Elliott Bros. of Sydney. Shortly afterwards, the Anaesthetic and Portable Machine Company of Sydney devised a machine that was functionally the same but also contained an electric lamp heater.Colour photograph of a modified Lidwill anaesthetic machine sitting on carpet, taken from above.

In 1913, Mark Cowley Lidwill designed a machine for the purpose of mechanical or insufflation anaesthesia. The Lidwill machine was a portable machine weighing 7kg that could easily be packed into two small bags. The machine involved compressed air being delivered to an ether vaporiser. An ether/air control device allowed varying concentrations of ether to be delivered. The ether vaporiser could be immersed in hot water to prevent cooling and the ether temperature was measured. From the vaporiser, the ether/air mixture went through a trap bottle, then to a crude mercury blow-off valve and subsequently to the patient.Large leather suitcase style bag divided into two levels containing and insufflation anaesthesia machine.insufflation, mark cowley lidwill, thoracic surgery, positive pressure

This is an early example of the Boyle's Anaesthetic Machine which was to become widely used throughout the world. The plaque on the wooden plinth suggests it was a display model from the medical equipment distributor Charles A King of London.The gas anaesthesia apparatus is mounted to a rectangular wooden base. It comprises two long, vertical glass cylinders held in place with metal brackets which are connected to a glass chloroform vaporiser container via metal tubes and associated valves and connections. The bottom of the glass flasks have outlet connections and inscriptions on the glass to measure volume. The chloroform vaporiser and adjacent glass ether vaporiser also have volume measurements etched on the glass, and the latter is the same height as the former but is larger in diameter. Both are connected via metal tubes and include outlet pipes that have associated cork stoppers. The maker's details are provided on a brass plaque attached to thewooden platform.A. Charles King Ltd.

Recognising that warmed ether was less irritating to the airway and patients receiving it were less likely to experience shock, Francis Shipway developed the Shipway's apparatus which was used during World War 1 and continued to be used through to World War 2. Reduction of shock for patients who had experienced trauma was crucial to their later recovery, particularly during war times. This example of the Shipway's apparatus also has the facility for administering chloroform.A triangular metal stand with two glass jars sitting in a metal tub and a green metal jar that looks like a thermos, also sitting in a metal tub. A metal pole has been screwed into the centre point of the stand, with a circular top to act as a handle. One of the jars has a rubber stopper in the neck with metal tubing attached to the stopper. The other glass jar has a metal screw top with a dropper spout. The two glass jars are connected via red rubber tubing. The apparatus has been sectioned in parts to show the inner mechanisms.Typed in black ink on white paper and adhered to metal bath: SHIPWAY'S APPARATUS •Typed in black ink on white paper and adhered to metal bath: ETHER VAPORISER •Typed in black ink on white paper and adhered to metal bath: THERMOS WITH HOT WATER •Typed in black ink on white paper and adhered to glass bottle: CHLOROFORM VAPORIZER •Typed in black ink on white paper and adhered to metal connector: TO AIR BELLOWS •Typed in black ink on white paper and adhered to tube in thermos: DELIVERY TUBE •Moulded into base of thermos: THERMOSshipway, world war i, warmed ether, endotracheal, chloroform
