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

The glass phial contained liquid ethyl chloride, little pressure being required to liquefy the gas at room temperature. By directing the nozzle downwards at the skin or mucous membrane to be analgesed, a stream of liquid squirts out, vaporising on contact, thus producing transient local temperatures of approximately -10 qc. Ether's unpleasant smell agitated patients. Ethyl chloride's pleasant odour reduced agitation. It could be used for induction and worked quickly without irritating respiratory passages. Ethyl chloride spray could also be used as a local anaesthetic. Faded rectangular burgundy box containing a glass phial with metal and rubber lid that forms a spray nozzle. The lid of the box had a mustard coloured manufacturer's label wtih burgundy writing.

Mark Cowley Lidwill was awarded an Honorary Fellowship in 1954 after his retirement to honour his working life.Mark Cowley Lidwill was born in England in 1878. His family moved to Melbourne in 1894. Lidwill studied medicine at the University of Melbourne, graduating with honours in 1902 and achieving a Doctorate in Medicine (MD) in 1905. Soon after graduation he moved to Sydney and in 1913 was appointed as the first lecturer in anaesthetics at the Royal Prince Alfred Hospital. That year Lidwill became the first person in the world to catch a black marlin with rod and reel. The event was celebrated in newspapers throughout the country and the marlin skeleton is now on display at the Australia Museum. Lidwill was also the designer of a machine which could deliver anaesthesia mechanically. Compact and portable, the machine delivered precise, although variable, concentrations of ether. Lidwill is also credited with developing the world’s first pacemaker. In a letter he wrote to Harry Daly in 1955, Lidwill was ambivalent about the fate of the machine: “No one would be bothered with it and they thought I was mad”.Printed certificate from the Faculty of Anaesthetists of the Royal Australasian College of Surgeons (RACS) awarded to Mark Cowley Lidwill as an Honorary Fellowship.

Between 1867 and 1920, anaesthesia for dental operations was often maintained by blowing the vapour of ether or chloroform into the patients' oral or nasal pharynx. Junker's inhalers are a "blow over" device used with a hand-held bellows to bubble air through liquid chloroform and to the patient. It was initially intended for use with bichloride of methylene, a mixture of chloroform and methyl alcohol. Ferdinand Ethelbert Junker introduced his inhaler in 1867 as appointed physician to Samaritan Free Hospital for Women (although it didn't have that name until c.1904). Glass jar with liquid measure markers etched onto. The jar has a metal lid, with a metal tube descending into the jar. Two metal tubes are protuding out of the top of the lid, and each has a small section of rubber tubing attached. There is also a metal hook, used to attached the jar to the physicians (anaesthetist's) lapel.Stamped into frame of metal lid: LONDON MADEjunker, blow over, chloroform, samaritan free hospital for women

Ether in oil was used for rectal anaesthesia. Rectal anaesthesia offered a way to administer anaesthesia when using a mask was impractical, such as oral or respiratory tract surgery. Undiluted ether was irritating to the bowel and even proved to be fatal.

Sidney Yankauer, M.D. (1872-1932), an ear, nose and throat specialist and pioneer in bronchoscopy, practiced at the Mount Sinai Hospital in New York. Dr. Yankauer, a prolific inventor of medical equipment, might best be known for the tube he designed for suctioning the mouth and throat. Yankauer introduced the wire-mesh anaesthesia mask around 1904. The drop method involved placing the mask over the patient’s nose and mouth, and then placing gauze over the mesh of the mask. Next, liquid anaesthetic, such as ether or chloroform, was applied in drops or lightly poured onto the gauze so that the patient breathed in evaporated anesthetic as well as air. The gutter around the base of the mask was designed to catch any residue of the harmful anaesthetic.

Dr. Joseph Clover (1825-1882), an English physician, first described his Portable Regulating Ether Inhaler on Jan. 20, 1877. Clover was an especially sought after anesthesiologist and early pioneer in the specialty. This was the best-known of many inhalers that Clover designed. The dome-shaped reservoir was turned to points on a control dial to gradually increase or decrease the percentage of the air that passed over the ether. Several inventors based new inhalers on this, while the original continued to be manufactured as late as the beginning of WWII. Clover, to spare the patient the unpleasantness of induction with his "closed" inhaler (1877), suggested the "mitigated-ether" technique. The inhaler was fitted with a bypass tap for the reception of N2O. The bag was filled with the gas and anaesthesia was inducted a combination of N2O and asphyxiation. Ether was then admitted gradually by rotation of the bowl of the inhaler. When the patient had been duly "weaned over" to ether, the mask was lifted, the N2O allowed to escape, the bag refilled with exhaled air, and normal anaesthesia "a la Clover's inhaler" was continued.Metal domed chamber with a bulb attachment for rebreather bag, including a tap mechanism.

Replica of original glass ether inhaler used by Dr William Russ Pugh in Launceston in 1847. William Russ Pugh is credited with being the first person in Australia to administer ether as anaesthesia. Pugh created his own ether inhaler based on a report in the London Illustrated News, dated January 1847. The paper reached Pugh in May and by June he had already designed, made and used the ether inhaler. On 7 June 1847 he performed two surgeries using anaesthesia. He also had a journalist present to record the event.The main container comprises an inverted funnel shaped glass jar that is connected to the top glass globe via an etched glass valve.

Dr James (Jim) Villiers went to Vietnam as an anaesthetist with the Australian Surgical Team (civilian) during 1963. He used this bag for carry-on luggage. Despite assurances about the quality of resources available on arrival, he carried an essential part of the breathing circuit for an EMO vaporiser in his carry-on. The actual vaporiser was packed in his check-in luggage. In 1963 the Vietnamese government sought training in Australia in anaesthetics for several medical technicians. Australia was not able to meet the request as anaesthesia training in Australia is restricted to qualified doctors. Instead, the Dean of the Faculty of Anaesthetists at RACS suggested sending a team of anaesthetists to Vietnam to conduct training for technicians there. However, they requested a preliminary survey be undertaken in order to determine the abilities of the prospective trainees and establish contacts with medical authorities in Vietnam. James (Jim) Villiers was one of the people who undertook the survey and made a report. Training of Vietnamese medical technicians was undertaken using the Epstein MacIntosh Oxford Anaesthetic Apparatus (EMO). This equipment was robust, portable and relatively cheap, there are few moving parts for servicing, it requires only ether and air for operation.Brick-red vinyl bag with white Qantas branding including the flying kangaroo printed on both sides.

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.

This equipment was located in the outpatients department (Philip Block) until September 2021 when it was deemed obsolete by Infection Prevention. Hubert Ingham Clements (1886-1969) was an Australian engineer who established his own engineering business in NSW in 1908 manufacturing combustion engines. He became interested in anaesthesia equipment and from the 1920s Clements worked on improving ether apparatus and manufacturing portable suction machines for use in hospital operating theatres. The latter machines were to earn an unrivalled reputation for reliability; many remained in service over thirty years after their date of production. The business became H. I. Clements & Son when his son William joined the company.
