Part of a collection of medical technologies donated to the Canada Science and Technology Museums Corporation by the Canadian Anesthesiologists’ Society. This machine was lent to CAS by Dr. Jeremy Sloan of North York, Ontario in 1995. Dr. Sloan is regarded as a leader in the promotion of safety standards for anesthetic equipment.

Fonction

Used to support the administration of anesthesia.

Technique

The original concept of Boyle's machine was invented by the British anaesthetist Henry Boyle (1875–1941) in 1917. Boyle promoted intratracheal insufflation techniques using nitrous oxide, oxygen and ether, replacing open-drop anaesthesia. Initially he used imported Gwathmey machines from the USA, but finding them unreliable, he developed his own continuous-flow machines. His design included cylinders for the gases and a "Boyle's Bottle" to vaporize diethyl ether. Until recently, an anaesthetic machine was often referred to as a "Boyle's Machine" in honour of his contribution. Dr. Sloan believes that this machine has an unsafe design because it was hard to assemble which often resulted in connection errors and issues during operation. (ref.1)
