    • A pulsatile blood circulating pump system for use in cardiopulmonary bypass, ventricular assist (LVAD, RVAD, BiVAD), ECMO, organ preservation, fetal cardiac bypass, cancer treatment, and areas of circulation research, which is controlled to produce blood flow that approximates physiological blood flow. The pump system includes a pulsating mechanism having a housing defining a chamber with a compressible-expandable bladder sealably mounted. A hydraulic actuator having a pressure imparting member that acts upon pressure transmissive fluid contained within the actuator chamber to generate a pulsatile pressure on the transmissive fluid, which results in pulsatile pressure being exerted on bladder to controllably vary the volume thereof. Additionally, the system includes a compact, motor that is associated with the hydraulic actuator for moving the pressure imparting member within the fluid chamber and further includes a fully programmable motion controller that controls the motor. The system includes a programmable touch-screen component to control the motion controller.
    • 用于体外循环,心室辅助(LVAD,RVAD,BiVAD),ECMO,器官保存,胎儿心脏旁路,癌症治疗和循环研究领域的脉动血液循环泵系统,其被控制以产生接近生理学的血流 血流量。 泵系统包括脉动机构,其具有限定腔室的壳体,其具有可密封地安装的可压缩可膨胀气囊。 一种液压致动器,其具有施加在致动器室内的压力传递流体上的压力施加构件,以在透射流体上产生脉动压力,这导致脉动压力施加在气囊上以可控地改变其体积。 另外,该系统包括紧凑的马达,其与液压致动器相关联,用于在压力腔内移动压力施加构件,并且还包括控制马达的完全可编程的运动控制器。 该系统包括可编程触摸屏部件来控制运动控制器。
