摘要: 本文在“血液锥形分离杯内血液流动稳定性的边界摄动解”[1]的分析基础上,对血液分离杯研制过程中出现的“已分层血液成份重新相混”的现象进行了分析,提出了合理的溢口几何形状,并分析了影响血液分离的各项物理参数. 理论分析得到上海医疗器械研究所实验的证实.Abstract: On the basis of "A Boundary Perturbation Solution for the Hydrodynamic Stability of Blood Flow in a Cone-Type Blood Processor"[1], this paper analyses the phenomenon of that the stratified blood composition Lecomes a mixture again, which occurs in the process of trial-producing with the blood processor, presents a reasonable shape of the flooding port and analyses each physical parameter affecting the blood separation.These theoretical analyses are in agreement with the experimental observations, which have heen made by Shanghai Medical Instruments Institute.
