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...
متن کاملPlatelet function during cardiopulmonary bypass using multiple electrode aggregometry: comparison of centrifugal and roller pumps.
Blood trauma may be lower with centrifugal pumps (CPs) than with roller pumps (RPs) during cardiopulmonary bypass (CPB), because, unlike RPs, CPs do not compress the tubing, and shear stress is considered lower in CPs than in RPs. However, relative platelet function remains unclear. Using multiple electrode aggregometry (MEA), we compared platelet function with CP and RP. Ten swine underwent CP...
متن کاملSome observations on industrial pumps for extracorporeal circulation in man.
Following the introduction by Gibbon (1937) of a practical method of extracorporeal circulation, many other machines have been developed capable of pumping and oxygenating blood. The mode of oxygenation has varied from machine to machine, but the circulation of the blood, with a few exceptions, has been carried out by some form of "tube" pump, because they are easy to sterilize. In such pumps p...
متن کاملAnalysis of the hydrodynamic profile in different roller pumps models used in cardiopulmonary bypass.
OBJECTIVE Among the equipments used in cardiopulmonary bypass the roller pumps have great importance with various models available from several manufacturers. The calibration is an important factor in hemolysis rates and its potential is different in each. Researchers do not always approach details on the pump bed profiles assuming that the standardized calibration settings ensure equal and com...
متن کاملAutomation of a portable extracorporeal circulatory support system with adaptive fuzzy controllers.
The presented work relates to the procedure followed for the automation of a portable extracorporeal circulatory support system. Such a device may help increase the chances of survival after suffering from cardiogenic shock outside the hospital, additionally a controller can provide of optimal organ perfusion, while reducing the workload of the operator. Animal experiments were carried out for ...
