The spindle pump is a combined working nonpulsatile blood pump, i.e., a centrifugally propelling device. This special concept was chosen to tackle the main problems of nonpulsatile pumps, such as thromboembolic complications, sealing difficulties, and traumatic hemolysis. The first two of these problems were relatively simple to solve compared with the third problem--traumatic hemolysis. Various modifications and constructive steps of the spindle pump were necessary to keep stress on blood components within adequate limits. The actual prototype--tested in three acute experiments and eight experiments with a longer pumping duration (the longest lasting 63 hours)--is described in extenso, and its development is discussed.
纺锤形泵是一种联合工作的无搏动血泵，即一种离心推进装置。选择这一特殊概念是为了解决无搏动泵的主要问题，如血栓栓塞并发症、密封困难和创伤性溶血。与第三个问题——创伤性溶血相比，前两个问题相对容易解决。为了将对血液成分的压力保持在适当限度内，纺锤形泵需要进行各种改进和建设性步骤。详细描述了实际原型——在三项急性实验和八项较长泵送持续时间（最长持续63小时）的实验中进行了测试，并讨论了其发展情况。
