The History of Cyprane

Abstract

The following fascinating account of apparatus history holds special interest for the Editor. With the advent of the value of trichloroethylene as an analgesic, an apparatus similar in concept to the Cyprane inhaler (Duke University Inhaler) was designed in the United States} and found favor. Later, with the introduction of halothane in 1956, as noted in the subsequent article, the Fluotec vaporizer was developed, which revolutionized the safe delivery of potent anesthetic drugs. Mr. Fraser Sweatman, a personal friend from Toronto, Ontario, bought the Cyprane Company and carried on the distribution of the Fluotec until his company was absorbed by the British Oxygen Company. And so the merger continues. WI! are much indebted to Dr. RS.
