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...
متن کاملComparison of gaseous microemboli counts in arterial, simultaneous and venous heat exchange with a hollow fiber membrane oxygenator.
Potential sources of gaseous microemboli during cardiopulmonary bypass are varied. However, it is known that membrane oxygenators generate fewer gaseous microemboli than bubble oxygenators and that bubblers cannot utilize arterial heat exchange without generating significant gaseous microemboli during rewarming. A membrane oxygenator utilizing simultaneous gas and heat exchange raises the con...
متن کاملTotal 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...
متن کاملMembrane Oxygenator with a Built-In Hemoconcentrator
In order to facilitate the handling of cardiopulmonary bypass (CPB) and simplify the circuit, we have developed a new membrane oxyganator with a hemofiltration function. The hollow fiber units for gas exchange and hemofiltration were combined in concentric circles in a cylindrical housing. The total priming volume was 190 ml. Because we used a silicon-coated hollow fiber membrane for gas exchan...
متن کاملExtraction of Nitroglycerin by a Membrane Oxygenator
This study examined the extraction efficiency of a membrane oxygenator for nitroglycerin (NTG). An In-Vitro cardiopulmonary bypass circuit was constructed to mimic clinical conditions. A NTG solution (150 ng/ml) was placed into the circuit via a glass cardiotomy reservoir and circulated at 5 Ll min for 60 min. Analysis of NTG samples obtained during the study showed that the oxygenator initiall...
