Mark V 高压注射器参数间关系探讨

Research on the Parameters of Mark V Injector

Mark V高压注射器参数的正确选择是决定心血管造影成功的关键。其中流率的选择更需恰当和准确。本文主要讨论了影响流率的相关因素 ,以及流率与压力限制之间的关系。总结出了一套典型的注射参数予置值。实验表明 ,使用浓度为 75 %左右造影剂 ,压力限制设置在 2 0 6 8— 5 5 15 k

This study sought to correctly preset the parameters of Mark v injection.The emphasis was laid on the flow rate in that,it ought to be set more carefully and more accurately for ensuring success in angiography.The authors analyzed the influential factors of flow rate and the relationship between flow rate and pressure limiting and hence proposed a set of typical presetting injection parameters.Experimental results demonstrated that with the contrast media concentration around 75%,high quality images could be obtained by setting the pressure limiting within 2068 5515kPa.
