A Disposable Screen Oxygenator

A disposable rotating oxygenator capable of being sterilized by heat for a heart-lung machine.

This rotating oxygenator is of a design differing from other rotating oxygenators in that the large surface area necessary for filming blood at high rates of flow is obtained by using a small number of concentric drums rather than a large number of discs. This makes for simplicity of manufacture and ease of assembly. The design is such that it can be cast in plastic in three parts and mass prod...

Can the oxygenator screen filter reduce gaseous microemboli?

Gaseous microemboli (GME) define small bubbles as < 200 microm in size. GME are reported to increase morbidity after cardiopulmonary bypass (CPB) and cardiac surgery. To prevent intrusion of GME into the systemic circulation during CPB, arterial line filtration is generally recommended. New trends in oxygenator design promote location of arterial filtration as an integral part of the oxygenator...

Disposable Screen Printed Electrochemical Sensors: Tools for Environmental Monitoring

Screen printing technology is a widely used technique for the fabrication of electrochemical sensors. This methodology is likely to underpin the progressive drive towards miniaturized, sensitive and portable devices, and has already established its route from "lab-to-market" for a plethora of sensors. The application of these sensors for analysis of environmental samples has been the major focu...

Total cardiopulmonary support with disposable membrane oxygenator during aortocoronary artery-vein graft operations.

Fifty-five patients received total cardiopulmonary support with the disposable Lande-Edwards membrane oxygenator during aortocoronary artery-vein graft operations and other complex open heart operations. Two three meter2 membrane oxygenators were linked in parallel to a standard r o b pump apparatus. (Three 3 meter2 membranes for patients weighing 80 to 103 kg.) Excellent oxygen and carbon diox...
