Période

This machine used c. 1950s,

Canada

Heart-lung machine was built by Dr. Campbell R. Cowan (b.1906) Banting and Best Dept. of Medical Research, University of Toronto, c. 1951. Dr. Cowan was a very talented designer and builder of mechanical devices. From 1930-1971 he served as Research Associate to Comptroller, Banting and Best Dept. of Medical Research (and with cross- appointment to Dept. of Physiology, University of Toronto) Cowan was largely responsible for the development of apparatus used by Dr. George Clowes in his surgical approach to the mitral valve of the dog's heart. He also developed an extracorporeal chamber making possible the study of extremely thin films of blood with particular reference to platelets, platelet clumping and thrombosis. Dr. Cowan published numerous papers with members of the Dept. on various subjects, including several with Dr. Best on the prevention of thrombosis. During WWII he served as an officer in the R.C.N. Medical Research division, studying protective clothing and ditching suits designed to provide greater protection for soldiers forced to abandon ship. (Ref. 4)
