In 1937, the engineer Holger Hesse founded Testa Laboratory, which later became Ambu. Hesse developed products that made a difference to patients and doctors. The real breakthrough came in 1956 when the Ambu ventilation bag reached the market, developed together with anaesthetist Henning Ruben. It was the world’s first self-inflating resuscitator and a major milestone in emergency medical equipment. The Ambu bag became a permanent part of hospital and emergency services product ranges.

Magill's laryngoscope with open straight blade and flat round speculum and a detachable light bulb connector, the bulb is missing. This laryngoscope is a previous version of the battery use ones conceived around 1920 therefore circa 1900. The design of the handle is similar to the Shipway laryngoscopes with a curved and pointed end and anatomical handle grip. The blade attachment place seems to be an adaptation to this kind of blade which differs from original models. The piece has several scratches and deep hit marks, as well as oxidation spots mostly around the internal canal of the blade. There is presence of resin residues on some surfaces. A visible different kind of metal was used at the blade base attachment place and for the light bulb connector.

Curt Theodor Schimmelbusch (November 16, 1860 – August 2, 1895) was a German physician and pathologist who invented the Schimmelbusch mask, for the safe delivery of anaesthetics to surgical patients. In 1890, Schimmelbusch invented a mask for the delivery of anaesthetics to surgical patients. It was primarily designed for ether anaesthesia, but he also proposed its use for chloroform anaesthesia. Schimmelbusch designed a metal mask, over which a gauze could be stretched and secured. The mask was placed over the patient's mouth and nose, and anaesthetic was applied to the gauze, allowing the patient to inhale the anaesthetic as they breathed normally. Around the edge of the mask, a trough collected the residual anaesthetic, rather than allowing it to drip onto the patient's face.Oval shaped metal mask with a collapsible cross-shaped dome, hinged clamp and flat handleStamped into underside of handle: ELLIOTT SYDNEYschimmelbusch, mask, open method, chloroform, ether, german, physician, pathologist

Cylindrical handle for battery deposit and with a wavy hand grip for easy handling. Serrated and screwed lids on top and base of the handle grip for insertion of batteries and checking of electrical contact stud. The handle also has a metallic switch without any instruction of use. The arm of the handle has a detachable screw to adjust extendable blade position and firmness. The light bulb is attached to a metallic tube connector to the handle arm which is just pressed to the contact point base. The blade has a oxidation spot under the blade.

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.

Hurley, Sir Thomas Ernest Victor (1888-1958) was gifted this Probyn Williams inhaler in 1914. After studying at Melbourne University, Victorian-born Hurley was a Medical Officer at the Royal Melbourne Hospital until he commenced private practice in Collins Street. He was appointed Captain Australian Army Medical Corps, AIF and served in Gallipoli with the 2nd Field Ambulance. He served in Enypt, London, and the Western Front during World War 1. He gained a Companion of the Order of St George and St Michael in 1917. Upon return to Melbourne he held positions such as surgeon to Victoria Police (1928-1956), elected to Council of the Victorian branch of the British Medical Association, member of the Charities Board of Victoria and foundation member of the Royal Australasian College of Surgeons and chaired the Flying Personnel Research Committee m a consulting surgeon at the Royal Melbourne Hospital.

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.

Dr Geoffrey Kaye was a clinical anaesthetist at a time when very few full time anaesthetists existed. He was passionate about the training of future anaesthetists and would often section anaesthetic equipment to reveal its inner workings and show those to students. This Probyn Williams Inhaler is one apparatus which has been sectioned and the various elements of the inhaler have been painted to highlight the differences in function.Oval shaped metal inhaler with attached metal facemask.

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
