用体外循环实现心肺转流是顺利完成心脏手术的先决条件，而血泵则是体外循环装置中的关键部件，其流量与压力等流体机械参数的控制和检测对保证心脏手术的顺利进行至关重要。该文综述了基于流量/压力、心率、心室功和血流辅助指数的几种血泵控制方法，并介绍了血泵流量与压力的直接和间接测量的方法。最后，结合血泵系统的研究现状，从血泵控制和检测方法等方面探讨了今后可能的研究发展方向。%Using extracorporeal circulation for cardiopulmonary bypass is the first step for the successful cardiac surgery, and the blood pump is the key component in extracorporeal circulation devices,the control and measurement of mechanical-fluid parameters such as flow rate and pressure are very important to guarantee the successful cardiac surgery. This paper reviews several control methods of the blood pump based on the flow rate/pressure,heart rate, ventricular work and blood assist index,and also discusses the direct and indirect measurements of the flow rate and pressure. This review concludes with the main possible trends for the further development of the blood pump control and testing methods.
