The De Ford Inhaler was introduced in 1913 and was designed to allow anaesthesia to continue through the nose while dental surgery was happening.This inhaler is composed of metal and rubber. The oral mask and rubber covered nasal mask are connected to a curved rubber covered support that was placed on the patient's forehead to hold the inhaler in place. The gas was administered via a long tube; the terminus designed to allow for the placement of a vial containing the anaesthetic drug and a rebreather bag mount.

The Coxeter-Mushin carbon dioxide absorber consists of the main metal body, painted aquamarine, fixed to a stand. The cylindrical silver metal cannister on the left was used to contain ether, while that on the right contained soda lime. The apparatus has been sectioned to show the inside of the two cannisters, the right of which has an arrow drawn inside to indicate the flow of air breathed out by a patient. The front cover over the control dials has also been removed to show the mechanism. The two circular holes above the dials, facing forward, are where two corrugated tubes would attach; both of these tubes attached to the mask of the patient. The round yellow knob in the centre controls the Compensating Valve, which allowed the anaesthetist to raise or lower the rebreathing bag to allow air into the circuit or expel anaesthetic gas.anaesthesia, carbon dioxide, ether, soda lime

With the introduction of nitrous oxide for patients undergoing dental treatment, 100% nitrous oxide was usually administered as an anaesthetic. This caused the patient to lose consciousness quickly and could also cause severe hypoxia. In the late 1890s, dentist Samuel Stockton White introduced this two cylinder apparatus, which could administer oxygen with N2O.Early model apparatus with cast iron stand, and two gas bottles.

Sir Frederick William Hewitt was a great advocate of nitrous oxide anaesthesia, mainly for short procedures. In 1885, he reviewed the methods of administration and concluded that accurately fitting valves were essential at the commencement of the inhalation, in order to ensure the rapid washout of air from the lungs; and there was a distinct advantage in allowing some rebreathing of nitrous oxide towards the end of inhalation. He thus devised the stopcock. The stopcock consists of a cylinder with two rotating sleeves and two rubber flap valves. The arrangement allows air to be breathed either through the valves or rebreathed to and from the bag; nitrous oxide to be breathed either through the valves from the bag and out to the atmosphere or rebreathed to and from the bag. Soon after the introduction of this stopcock, there was an increased interest in administering oxygen in combination with nitrous oxide.Amber coloured ether inhaler, with leather mask, celluloid shield and inflatable cushion with attached Hewitt's stopcock.hewitt, stopcock, celluloid, ether, inhaler, mask, rebreathing

This Boyle’s machine was made by the British Oxygen Company (BOC) in the 1950’s. The original Boyle's machine was invented by the British anaesthetist, Henry Boyle in 1917. His machine was a modification of the American Gwathmey apparatus of 1912, and became the best known early continuous flow anaesthetic machine. The Boyle’s machine was first made by Coxeter and Sons, under the direction of Lord George Wellesly, which was later acquired by the British Oxygen Company (BOC). Though a lot of changes have been made to the original design of the Boyle’s machine, the basic structure remains the same today.Green trolley on casters with flowmeter and vaporiser bottles attached to a stainless steel cross bar. There is a glass shelf at top of the trolley and a second glass shelf at base of trolley, above a pull out drawer.

Mechanical resuscitation devices, such as the Pulmotor and Lungmotor, were popular in the early part of the twentieth century. Their use waned in the 1920s as significant bodies like the British Medical Research Council and American Red Cross refused to endorse them. The most popular of the resuscitators to emerge in the 1930s was the E&J (Ericson and Johnson) resuscitator. The device was soon widely available, vigorously promoted with support from many medical practitioners. They were soon to be found in hospitals, emergency services like the ambulance and fire brigade, and voluntary life-saving organisations. In Australia, Norman James, director of anaesthesia at the Royal Melbourne Hospital, developed an interest in equipment for ambulances and the resuscitation of drowning victims. Little in the way of practical, portable equipment was available to either the ambulances or the voluntary life-saving organisations, such as Surf Life Saving Australia (SLSA); American resuscitators, like the E&J, were expensive and bulky to import. James designed a simple portable resuscitation device for local use after being approached by Jack Conabere, secretary of the Elwood Life Saving Club (ELSC). The resulting Royal Melbourne Hospital resuscitator, or the R.M. resuscitator as it was marketed, was a simpler, manual version of those available overseas. It was gas driven with a plunger, marked “Press”, and a safety valve. The small working unit attached directly to the facemask. Once the patient was positioned facedown and the airway cleared of debris, the mask was placed firmly over the face. The plunger allowed gas to flow and lung inflation; releasing the plunger allowed expiration. This simple resuscitator was marketed by Commonwealth Industrial Gases (CIG) and became very popular in Australia with volunteer and professional rescue organisations. It represents one of the many innovations in resuscitation equipment that resulted from cooperation between volunteer life savers and medical practitioners. Norman James worked closely with Jack Conabere and the Government Pathologist to develop the equipment. ELSC was the first life saving club to use the resuscitator on the beach. While conducting an early training exercise on 23 December 1951, they used it to successfully resuscitate a man who had drowned after capsizing his home made yacht. The R.M. resuscitator was also used in more inventive ways. At Fairfield Hospital in Melbourne, a group of physiotherapists and doctors did some innovative work with polio patients, teaching them glossopharyngeal (or “frog”) breathing, as a means of becoming less dependent on ventilators. In 1981, the Australian Standards Association stated that the RM head failed to meet its revised standards and it was withdrawn from the market.

There is a space allocated for two oxygen cylinders, however there are no cylinders present.Embossed into metal plaque: The C.I.G. / Oxy-viva / PORTABLE UNIVERSAL OXYGEN RESUSCITATORresuscitation, portable, surf life saving australia, royal melbourne hospital, rm resuscitator
