Période

Used 1946- 1947.

Canada

First artificial kidney machine made in North America by Dr. Gordon Murray, simultaneously and independently of Willem Kolff's invention in Holland in the 1940s. Designed and built by Murray himself, it was used successfully on four patients at Toronto General Hospital, 1946-47. Murray was a remarkable surgeon and innovator whose work earned him international recognition. In the 1930s Dr. Murray introduced the anticoagulant Heparin to world clinical practice; in the '40s he developed the first artificial kidney in North America; and in 1955 he performed the first successful transplant of a human heart valve. Unfortunately, these achievements are often overshadowed by his later, controversial work on an anti-cancer serum, and on unconventional surgery for injuries caused by traumatic paraplegia. (Ref. 3]

Fonction

Used to circulate blood through dialysate solution.

Technique

Murray's artificial kidney used a pump, rather than gravity, to circulate blood through filtering medium. The design of the pumping system was problematic: the system could not crush blood corpuscles, cause clotting or produce hemolysis, and had to operate smoothly and efficiently. Murray's design incorporated an electric motor-driven syringe which inflated and deflated a rubber tambour (condom). [Ref. 5] Blood flow was controlled by intake and outlet valves. [2002.0620, Ref. 8] Elements of this assembly were used in the earliest version of Murray & Roschlau's artificial kidney machine [2002.0620] The metal base, supports, electric motor and reciprocating rod were among these "recycled" elements. [please see photographs, Ref. 6]
