Abstract
A new method for producing pulsatile flow during cardiopulmonary bypass is described. The method requires only the addition of a dilated segment in the tubing which passes beneath the arc of a standard roller pump. Preliminary studies demonstrate that pulsatile flow and pressure with physiologic contours can be produced by this "bubble tube" system. Furthermore, the new tubing causes less hemolysis than standard pump tubing.
摘要
描述了一种在体外循环期间产生搏动性血流的新方法。该方法仅需在通过标准滚压泵弧下方的管道中添加一个扩张段。初步研究表明，这种“气泡管”系统可产生具有生理轮廓的搏动性血流和压力。此外，新管道比标准泵管道引起的溶血更少。
