Context

Country: Canada
State/Province: Ontario
Period: Used c. 1951-1953.
Canada: Second artificial kidney designed and manufactured by Drs. Gordon Murray and Walter Roschlau at W.P Caven Research Foundation, Toronto c. 1951-1953. It was used experimentally in his laboratory on Holmwood Ave. (site of the CRV) and once for emergency treatment on a patient suffering kidney failure at Toronto General Hospital. [Ref.4] Murray's second-generation machine was an improvement from the original: it's design features made it more compact and efficient, easier to handle, set-up and use, and less intimidating for both patient and hospital staff. [Ref. 8] Murray abandoned his renal dialysis research c. 1954 . 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. (2002.0619 Ref. 3]
Function: Part of assembled filter unit of artificial kidney machine.
Technical: Inflow and outflow occur through holes that form (when mounted) vertical conduits with slits into and out of the blood chambers. The thickness of each blood chamber is approx. 0.75 mm, with a dialyzing surface of approx. 100 cm squared x 2, resulting in an approx. capacity of 7.5 mL per blood chamber. Diagonally opposed corners of blood and dialysate chambers are rounded for identification, and must be matched when assembled within dialyzer. [Ref. 5]
Area Notes: Unknown
