Période

This unit used during the 1960s.

Canada

This machine was used at the Toronto General Hospital in the 1960s, during open heart surgeries. It replaced the Heimbecker oxygenator, and was in turn replaced by membrane oxygenators in the 1970s. [Ref. 2]

Fonction

To remove carbon dioxide waste gases from the blood and infuse it with oxygen before circulating it back through the body.

Technique

Designed by Earle B. Kay and Frederick S. Cross, and used in open heart surgeries performed at St. Vincent's Charity hospital in Cleveland, Ohio. 1956+. It's design is based on the Bjork oxygenator (c. 1948) which was used experimentally in animal studies. Rotating in the venous blood fed into the oxygenator cylinder, the discs turned at speeds of up to 120 RPM. This created a thin film of blood on the discs within the oxygen rich cylinder, but no bubbling or foaming [of blood]. The oxygen-infused blood was then circulated back through the patient's body. This device, though effective, was heavy, difficult to sterilize, and required an enormous amount of time to prepare for use. It also required a large amount of venous blood to prime. It was replaced by alternate designs.[ Refs.4 & 5] For detailed technical information on component parts, please see 1962 Pemco catalogue entry for Oxygenator.
