Magill's laryngoscope, A Charles Kind, Ltd
... Geoffrey Kaye Museum of Anaesthetic History ANZCA House 630 ...This object is Magill's adaptation of the battery handle in the form of an "inserting tracheoscope". Introduced in 1935 for one-lung anaesthesia, it is combined with an endotracheal tube, the central part of which is a latex-covered wire spiral, and a bronchus blocker. In use, the tube was fixed to the holder and the whole apparatus inserted as a ttracheoscope. At the carina, the blocker was inserted into the bronchus and the balloon (now perished in this example) inflated. The holder was then removed leaving the endotracheal tube and blocker in place. The bronchus blocker consists of gum elastic on woven silver wire and has a suction channel opening at the tip. in other stages of development of Magill's laryngoscope, the original pattern blade was adapted to the battery handle, at first in a fixed arrangement and then with interchangeable blades of different sizes. Later still, the folding handle was introduced.This U-shaped chrome plated laryngoscope comprises an endotracheal tube used to facilitate access to the patient's airway, wire spring attachments and a cylindrical handle with provisions for battery to illuminate inside the body during use.Embossed on the central shaft of the item is 'A Charles King, Ltd', the maker's details.laryngoscope, anaesthesia, macgills, chrome, battery, a charles kind ltd -

Archie Brain laryngeal mask and airway, Dr Archie Brain, circa 1982
... Geoffrey Kaye Museum of Anaesthetic History ANZCA House 630 ...Taking castings from the larynx of cadaver's, Archie Brain studied the anatomy and physiology of the upper airway in minute detail. He devised the Laryngeal Airway Marsk (LMA) as an alternative to endotracheal intubation. Since first gaining a patent in 1982, he produced over 1000 prototypes over the next 30 years in a constant effort to improve the device and patient safety. The LMA is a recent innovation and provides an alternative to endotracheal intubation and has made a significant contribution to safe airway management. Ovoid shaped black rubber layrngeal airway with orange access point stopper. Translucent rubber tube is glued into the airway and is cutaway within the internal space of the airway.

Inhaler, Ether, Small
... Geoffrey Kaye Museum of Anaesthetic History ANZCA House 630 ...Dr Thomas Small designed this ether anaesthesia and analgesia machine while he was an Honorary Medical Officer at the Royal Women's Hospital in Sydney during the 1930s. The inhaler is compact and portable. Initially, Small experimented with other agents for the relief of labour pain but was not happy with any of them. He also tried various agents on himself, including nitrous oxide/oxygen, chloroform and ethyl chloride. Finally he settled on ether via a Clover inhaler as the best analgesic. This inhaler is only described in use in Australia and New Zealand, although it was used for almost 40 years. Black leather box with leather handle, lockable latches on either side and drop down front case panel containing a metal ether inhaler and length of black corrugated rubber hose with one end attached to the inhaler and the other end open for attaching a mask. The metal inhaler drum is circular and attached to the floor of the case with a small tap/lever to one side and a mixing valve on the top near the hose connection. The lever has incised gradings of quarter increments from 0 to 1. The box is designed for the ether inhaler to be portable.ether, small, thomas, analgesia, obstetrics, anaesthesia, anaesthetic, royal women's, sydney, queen victoria, melbourne
