We have developed an autoflow control system for the Terumo Capiox centrifugal pump, the SP-101. First, we made an external control system regulated by a personal computer through a serial communications line. Although an in vivo experiment using a goat showed excellent performance in regulating the flow, a communication error that caused an abrupt and instantaneous flow fluctuation was noted occasionally. Therefore, we incorporated a check-sum function to solve this problem. After this improvement, 5 patients safely underwent cardiopulmonary bypass using a pump having this autoflow control. As the next step for more practical usage, we developed a built-in autoflow control system in which the control device is entirely incorporated into the console without a communications line. This system demonstrated better response and reliability than the external control system and was applied successfully in 3 patients. In conclusion, this autoflow mode will expand the usage of centrifugal pumps through improved handling.
我们已经为Terumo Capiox离心泵SP - 101开发了一种自动流量控制系统。首先，我们制作了一个通过串行通信线路由个人计算机调节的外部控制系统。尽管使用山羊进行的体内实验在流量调节方面表现出色，但偶尔会出现通信错误导致流量突然瞬间波动的情况。因此，我们加入了校验和功能来解决这个问题。经过这一改进，5名患者使用具有这种自动流量控制功能的泵安全地进行了体外循环。作为更实际应用的下一步，我们开发了一种内置自动流量控制系统，其中控制装置完全集成在控制台内，无需通信线路。该系统比外部控制系统表现出更好的响应性和可靠性，并成功应用于3名患者。总之，这种自动流量模式将通过改善操作来扩大离心泵的使用范围。
