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
