Abstract

For in-depth research of blood flow, it is important to create pulsating flow like the blood flow from heart beat. In this study, we developed a heart mimicking pulsatile pump and evaluated its performances. Main body of pump was produced using a piston pump, and its rpm and duty ratio was modulated by DC motor and encoder. To determine the part dimensions, principle stress theory and simple fluidic pressure analysis were used. The performance of pulsating pump was evaluated by comparing the pressure values and their deviations according to experimental variables. For the results, the output value of pressure followed the distribution of pulsating flow and its deviation was negligible. Through this study, we expect the established pulsating pump can be widely used in study of blood flow produce easy ways to related researchers.

혈류 유동 연구를 위해서는 심장의 맥동 유동을 만들어 내는 것이 중요하다. 본 연구에서는 동맥혈류의 유동 해석을 위해 새롭게 설계된 심장 박동 모사 맥동펌프의 제작 및 그 성능에 관하여 시험을 수행하였다. 피스톤 펌프를 이용한 기본몸체 설계를 수행하였고 직류모터와 엔코더를 사용하여 회전수와 가속비를 설정할 수 있도록 하였으며, 시험결과는 전 영역에서 맥동 유동의 분포를 잘 따르고, 반복되는 맥동 주기의 편차도 작게 나타남을 확인하였다.
