为了提高驱动依赖于后负荷的离心泵的简易性，我们为Terumo Capiox离心泵系统开发了一套自动流量控制系统。该系统由带有安全截止点的自动流动巡航控制系统组成。Capiox泵控制台3000由个人计算机通过串行通信线路控制。在通常的手动模式中，电机速度旋钮作为泵的速度控制，而在自动流动模式中，相同的旋钮作为血流速度控制。在选择并获得所需的流量后，模式从手动改变为自动流动模式。在自动流量模式下，计算机将期望的流量与超声多普勒流量计测量的实际流量进行比较，并相应地调整电机转速。在体内和体外测试中，这种自流模式能够将因夹紧和解夹管子或通过团注血管舒张剂而中断的改变的流量恢复到所选的流量10 S以内，而没有任何明显的波动。总之，新开发的计算机控制自动流量系统能够为离心泵提供可靠而有效的流量调节。
To improve the ease of driving a centrifugal pump that is afterload dependent, we have developed an automatic flow control system for the Terumo Capiox centrifugal pump system. This system consists of an autoflow cruise control system with a safety cutoff. The Capiox Pump Console 3000 was controlled by a personal computer through a serial communication line. In the usual manual mode, the motor speed knob works as a pump speed control, and in the autoflow mode, the same knob works as a blood flow rate control. After selecting and obtaining the desired flow rate, the mode was changed from manual to autoflow mode. In the autoflow mode, the computer compares the desired flow rate with the actual flow measured by an ultrasonic Doppler flowmeter and adjusts the motor rotational speed accordingly. During both in vivo and in vitro testing, this autoflow mode was able to return the changed flow that was disrupted by either clamping and declamping of the tubing or by the bolus injection of a vasomotor drug to the selected flow rate within 10 s without any significant fluctuation. In conclusion, the newly developed computer controlled autoflow system was able to produce a reliable and effective flow regulation for a centrifugal pump.
