Part of a collection of medical technologies donated to the Canada Science and Technology Museums Corporation by the Canadian Anesthesiologists’ Society. This object was on display as part ‘An Exhibit on Inhalers and Vaporizers, 1847-1968’ at CAS’s Annual Meeting in Ottawa in 2003. Given to the Canadian Anaesthetist’s Society by Mr. A Charles King in June 1953.

Fonction

Used for the administration of ether by inhalation for anaesthesia.

Technique

“The ether inhaler invented by John Snow (1813-1858) is of interested because it incorporates the basic principles of vaporization of anesthetic gases. Within two weeks of first seeing ether administered in London in December 1846, Snow designed this forerunner of modern vaporizers. Realizing the importance of ambient temperature on the vaporization of ether, Snow at one determined how much ether vapor would be held in air at different temperatures. He wrote, “…by regulating the temperature of the air while it is exposed to the ether, we should have the means of ascertaining and adjusting the quantity of vapour that will be contained in it.” In March 1847, Snow had a prototype inhaler constructed, and in June 1847 the definitive one, exhibited here, was made. Snow also designed a chloroform inhaler.” (ref.2) The components of the inhaler are as follows: Japanned metal box, as bath for water at 50 to 60 degrees F; a vaporizing chamber containing spiral baffle attached to roof and extending to 1/16 of an inch of the floor; metal tube screwed into box for ingress of air; breathing tube (wider than trachea; and mask and one-way valve.
