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.

Function

Covers mouth and nose in order to administer general inhalant anaesthetic

Technical

“The principle of safe self-administration of analgesia with Trilene was well established when Drager manufactured its Bar inhaler. Like the Oxy-Columbus and Duke inhalers, it was loosely secured to the patient, hand-held, and used to relieve the pains of labour. Overdosing was said to be “practically impossible,” as the inhaler fell from the hand with the onset of semi-consciousness. As well as its use in obstetrics, the Drager inhaler could be used to relieve the pain of minor surgical procedures. The inhaler could be applied over the nose or the mouth, depending on the ancillary equipment. The inhaler was designed so that the concentration of Trilene could not exceed 1%. A built-in thermostat compensated for the decrease in temperature of the Trilene as vaporization proceeded.” (ref.1)
