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 WWIIMetal based inhaler with glass dome lid. From the glass dome an elbow joint leads to a bulb for a rebreather bag [no bag]. There is a cork sealing an opening at the rear of the metal base and a blue sticker adhered.Printed in white on blue sticker: O.2.10 Manufacturer's logo moulded into metal insertjoseph clover, portable regulating ether inhaler

Sir Frederick William Hewitt (1857-1916) wrote one of the earliest comprehensive textbooks on anaesthesia, and designed several pieces of anaesthetic equipment. In 1901, he described his wide-bore ether inhaler, a modification of the Clover Ether Inhaler. Unlike the Clover, it can be refilled with ether while still in use, and the mask is screwed into place so that it "cannot be unexpectedly detached." This version is a modified Hewitt's Inhaler which has a narrower 'ways' than the original Hewitt's, and no water compartment. Additionally, one side of the bowl is made of glass which enabled the person administering anaesthesia to see the level remaining in the bowl. Bowl shaped inhaler with a glass bowl base and metal dome top with a connector which appears to be for a rebreather bag. There is a metal switch at the base of the glass bowl to alter or regulate the flow.Stamped into central tube: COXETER LONDON Stamped into side of metal dome: 6460hewitt, wide-bore, clover, ether, anaesthesia, anesthesiology, anaesthesiology

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

Lambert Ormsby was a New Zealand surgeon who migrated to Ireland. He described his inhaler in a letter to the Lancet in 1877.Ormsby listed the advantages of his inhaler as simple, inexpensive, small quantity required to produce sleep, prevents evaporation of ether, portable and small (can be carried in pocket), short time to complete anaesthesia (two minutes) and safe. Disadvantages of this apparatus were that it had to be removed in order to recharge the sponge with ether or when anaesthesia becomes too deep. Considerable carbon dioxide accumulation developed and there would also be some oxygen lack. In thirty years of use, Ormsby's Inhaler underwent certain modifications, an exhalation valve was fitted to the mask and device for recharging the sponge with ether was later added. The Ormsby inhaler was modified by Carter Braine in 1898 with the aim of making it easier to clean. Essentially it is very similar except there is no net around the bag.The inhaler consists of an india-rubber flexible bag enclosed within a net bag to limit expansion. There is a soft metallic mouthpiece with india-rubber tubing around the edge. The tubing had to be purchased separately from the manufacturer. The body contains a wire cage with a similarly shaped hollow sponge into which ether was poured.Maker's details inscribed into metal ring around the bore: Barth Co.

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. Sea sponges are located within the glass vessel and the woven cloth tube is connected to the base of the glass container. inhaler, anaesthesia, william russ pugh, replica, glass, sea sponge, ether, launceston, illustrated london news, lady howden, dr john belisario, dr gwen wilson

This item was designed by surgeon Paul Herman Martin Sudeck to administer ether and then chloroform anaesthesia. Paul Hermann Martin Sudeck was a German surgeon (28 December 1866 - 28 September 1945). He first described his inhaler in a 1903 article, "Eine neue Aethermaske" (A New Ether Mask).The metal cone shaped mask has moulded features on the proximal end to fit over the patient's mouth. The distal end is rounded and has an area for the absorbent material (in this item, a sponge) through which the anaestheric ether or chloroform was dripped. The side 'arms' would have been used to attach a strap.inhaler, mask, cone, paul herman martin sudeck, germany, ether, chloroform, sponge, 1900

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.

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.

When Hewitt introduced his regulating stopcock in 1887, attempts were made to dilute the nitrous oxide with air and so obviate the element of asphyxiation. The method was to be seen in London, mainly in dentistry and minor surgery, so late as 1930. It was not very successful. To give even 10% of oxygen (which is not enough) the gas-mixture must contain 55% of air and 45% of nitrous oxide. The latter is thus so diluted by atmospheric nitrogen as to be incapable of producing anaesthesia except by asphyxiation. "Gas-air" was confined to analgesia, for example in midwifery.

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.
