乳幼児啼泣時の点滴留置針まわりの血栓形成とそのモデルのCFD による流動解析

抄録

This paper describes the relation between infantile crying and thrombus generation near intravenous indwelling needle in veins. In this study, it is assumed that the difference of pressure or flow rate between normal and infantile crying causes thrombus formation. First of all, the blood pressure of infant are measured, and the difference of blood pressure between normal status and infantile crying. It was found that the blood pressure increases according to the infantile crying, and the difference of blood is approximately 20 mmHg. To investigate the flow field of the flow, CFD analysis around the indwelling needle of drip injection (catheter) in the infantile vein was done. The results show that the increasing flow rate or velocity make the accumulation of particle around the inlet of the catheter.
