Summary
Experiments on the oxygen transport in a Taylor-vortex membrane oxygenator have shown that it is a highly efficient mass transfer device. A theoretical estimate of the haemolysis rate, based on a mathematical model for flow in a Taylor-vortex system, has shown that high shear stresses will be the main limitation in the design of this oxygenator. Setting an upper limit to the average wall shear stresses, a design analysis indicates that highest possible rotational speed and long cylinders give the best overall performance. Experimental experience suggests that practical difficulties limit rotational speed to 600 – 800 rev/min and the cylinder length to 40 – 60 cm, which results in a mean diameter of 30 – 35 cm and an annular gap of 3 – 5 mm for a full size oxygenator. The clinical acceptance of the Taylor-vortex oxygenator will depend upon whether a possible reduction in haemolysis can outweigh the drawbacks of large priming volume and overall size.
