The use of plastic tubing in roller pumps.
If plastic tubing is to be used in roller pumps for propelling blood in extracorporeal circulations under occlusive conditions spring loading the rollers and accurately setting the spring force is essential. Various types and sizes of plastic tubing are compared and their performance estimated; rubber tubing used for the same purpose has been tested. The optimum spring force has been determined both for plastic and for rubber tubing.
