Abstract
本发明公开了一种基于超声导波的凝血指标检测系统及方法，所述方法包括：根据获得的粘弹性变化曲线，计算得出样本相应的凝血指标；包括：凝块起始时间，定义为血液样本置入凝血指标检测系统后至初始纤维蛋白开始形成的时间间隔，对标金标准方法TEG检测结果的R时间；凝块稳定时间，定义为血液样本形成凝块时间，对标金标准方法TEG检测结果的K时间；θ角度，用于衡量纤维蛋白生成与交联的速度，对标金标准方法TEG检测结果的α角度；最大凝块强度，对标金标准方法TEG检测结果的MA值。相较于TEG方法，本发明显著缩短了凝血指标的检测时间，为术中紧急凝血功能评估及血液制品合理应用提供了时间保障，有利于改善临床预后。
