本文按研究左心室辅助血泵的需要,设计了一套简易的体循环模拟装置,在固定条件下,对离体羊全血进行转流,检查转流前后羊血质量的变化,实验结果如下。 在转流前和转流后1、2、3小时分别釆血样测定血液pH值和红细胞比积,所得结果表明:转子泵加助搏筒型泵和单纯转子泵两种循环方式,对羊血的pH值、红细胞比积转流前后没有明显差异;红细胞电脉时间在转流后稍有 In this paper, according to the need of researching the left ventricular auxiliary blood pump, a simple set of systemic circulation simulation device is designed. Under fixed conditions, the whole blood of isolated sheep is diverted and the quality of sheep’s blood before and after the bypass is examined. The experimental results are as follows. Blood samples were taken before and 1, 2, 3 hours after the bypass to determine the blood pH and hematocrit, respectively. The results showed that the rotor pump plus the spiral pump and the simple rotor pump were both recycled, PH, no significant difference in hematocrit before and after the commutation; erythrocyte pulse time slightly after the bypass
