This paper describes the design of a servo-controlled precision roller pump applicable for constant blood flow or constant blood pressure perfusion in research on the peripheral circulation. The pump, and its feed-back control, can simulate normal cardiac induced autoperfusion by reproducing the arterial pulse pressure configuration with high fidelity. Its design is such as to minimize damage of the red blood cells and consequent release of vasoactive substances, a problem encountered with most conventional pumps. The present pump principle may also find a use in heart-lung machines and dialysis equipment and can be used as a precision infusion pump.
本文描述了一种适用于外周循环研究中恒定血流或恒定血压灌注的伺服控制精密滚轴泵的设计。该泵及其反馈控制能够通过高保真地再现动脉脉压形态来模拟正常心脏诱导的自身灌注。其设计旨在最大程度减少红细胞损伤以及随之而来的血管活性物质释放，这是大多数传统泵所面临的问题。目前的泵原理也可应用于心肺机和透析设备，并且可用作精密输液泵。
