MAGILL APPARATUS - circa 1927
Date of manufacture:
CHARLES KING Ltd., Devonshire St., LONDON.
This Magill Endotracheal Apparatus was introduced in 1927. It incorporates dry gas flow meters for oxygen nitrous oxide and CO2. The rectangular container below the manometer contains warm water to warm the cylindrical vaporisation chamber above it. Ether is drip fed from the top rectangular container at a rate controlled by the top knurled knob while observed in the drip chamber. By this means, the rate of vaporisation of ether is limited only by the drip rate as long as the water temperature remains sufficiently high to vaporise all the liquid arriving in the vaporisation chamber. It is complex, compact and portable, designed for the peripatetic anaesthetist. The outlet incorporates a bag-mount and is wide bore.The glass bottle vaporiser at the back is probably intended for chloroform.
