Detail of vaporisers.This is the back bar for a Boyle's type anaesthetic machine with vaporisers for ether and trilene, flowmeters for oxygen, cyclopropane and nitrous oxide, and a rebreathing bag. The apparatus was made by the British Oxygen Company Ltd, London. These components fitted onto an anaesthetic trolley. It is an example of a continuous flow anaesthetic machine which works by supplying compresed gases from cylinders through vaporisers to the patient through a breathing circuit. Boyle's type machines are named after the London anaesthetist H E G Boyle (1875-1941).
