The spindle pump--a new nonpulsatile bloodpump--has been developed as paracorporeal ventricular assist pump. The experiments with calves clearly demonstrated, that this pump as LVAD empties the left ventricle completely, the aortic pressure curve showing the typical nonpulsatile profil. A problem is the traumatic hemolysis, the free hemoglobin was in all experiments slightly but always above our standard. To solve this problem we will optimize shapes of the spindle and of the housing and coate all parts of the pump with polyurethane.
纺锤形泵——一种新型非搏动性血泵——已被开发用作体外心室辅助泵。在小牛身上进行的实验清楚地表明，作为左心室辅助装置的这种泵能使左心室完全排空，主动脉压力曲线呈现出典型的非搏动性形态。一个问题是创伤性溶血，在所有实验中游离血红蛋白含量虽轻微但始终高于我们的标准。为解决这个问题，我们将优化纺锤体和泵壳的形状，并对泵的所有部件进行聚氨酯涂层处理。
