摘要： A pumping system 10, Figure 1 , provides a physiological pulsatile flow and includes controller 121, a pump drive head 50 coupled to a motor 12 and a fluid housing 52 having at least one port 60. The post 60 includes a ball valve retainer region 69, a valve seat 73, and an occlude ball 71 disposed in the ball valve retainer region 69. During operation, the motor 12 forces the fluid in and out the fluid housing 52 and causes the occlude ball 71 to move from a first position whereby the fluid cannot pass through the port 60, so a second position whereby the fluid moves annular to and generally around the occlude ball 71. This movement creates a slight flow reversal that "breaks up" any blood clots that may form. The pumping system may be used as part of a cardiopulmonary bypass system, a ventricular assist device (VAD) and/or a heart pump.

摘要翻译：图1中的泵送系统10提供生理脉动流，并且包括控制器121，联接到马达12的泵驱动头50和具有至少一个端口60的流体壳体52.柱60包括球阀保持器区域69 ，阀座73和设置在球阀保持器区域69中的闭塞球71.在操作期间，马达12迫使流体进出流体壳体52，并使闭塞球71从第一位置移动，由此，流体不能通过端口60，所以第二位置使得流体环绕到闭塞球71周围并且通常围绕闭塞球71.该运动产生轻微的流动反转，“分解”可能形成的任何血块。泵送系统可以用作体外循环系统，心室辅助装置（VAD）和/或心脏泵的一部分。
