Abstract: Conventional medical-device evaluation often involves animal experiments and clinical investigations, both of which require substantial time and resources and are subject to ethical and practical constraints. Both require significant investment and a long period of time, have numerous ethical constraints, and once the testing plan is set, it is difficult to make changes. It is even more challenging to conduct innovative tests. With the acceleration of device updates, this verification model has become increasingly strained. Cardiovascular and cerebrovascular diseases impose a substantial clinical burden, and the performance of related medical devices directly affects treatment outcomes and postoperative recovery. The pressure on public health prevention and control is constantly increasing. At the clinical level, the performance of cardiovascular and cerebrovascular devices directly affects the treatment outcome and postoperative recovery quality of critically ill patients, and they are indispensable equipment in intensive care. The introduction of the extracorporeal circulation circuit system has opened up a new way for verification work. This system can simulate the real hemodynamic conditions of the human cardiovascular system, and the experimental parameters can be adjusted as needed, precisely compensating for the shortcomings of traditional methods. This article focuses on the engineering implementation and application of this platform. Based on experimental records and long-term practical experience, the author explains the hardware composition, operating characteristics, and simulation accuracy of the system, and combines detection examples of interventional and circulatory support devices to examine their actual test results. During the experiment, some problems have also been gradually exposed: there is still a deviation between physiological simulation and the real environment, the performance stability of the supporting consumables is poor, and the industry test standards have not yet been unified. These aspects constitute the key topics of discussion in this article. The above research results provide a basis for the structural optimization, parameter calibration, and standard formulation of the extracorporeal evaluation system, and have direct reference significance for the preclinical verification of similar medical devices.
