Description

血压采集终端及获取有创动脉压力的方法及冠脉分析系统
本申请要求在2019年9月18日提交中国专利局、申请号为201910883255.X、申请名称为“血压采集终端及获取有创动脉压力的方法及冠脉分析系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及冠状动脉医学技术领域,特别是涉及一种血压采集终端及获取有创动脉压力的方法及冠状动脉分析系统。
背景技术
血流储备分数(FFR)指在冠状动脉存在狭窄病变的情况下,该血管所供心肌区域能获得的最大血流与同一区域理论上正常情况下所能获得的最大血流之比,即心肌最大充血状态下的狭窄远端冠状动脉内平均压(Pd)与冠状动脉口部主动脉平均压(Pa)的比值。要计算血流储备分数(FFR),就必须借助设备先获得主动脉压数据,如主动脉压的收缩压、舒张压和平均压等。
通过血压仪测量主动脉压数据存在瞬时性,并不能够实时监测。
现有技术实时监测主动脉压数据是通过一根导联线与传感器连接,传感器使用了一个相对简单的塑料板(传感器支架)来固定。这样的方式与监护仪的方式相同,但并不适用于测量血流储备分数,过程中有很多不方便的地方。原因如下:FFR测量一次的时间大约只有20分钟左右,监护一次的时间单位一般以小时为单位,所以操作者一天内,安装、卸下血压传感器的次数也会因此增多,而血压传感器都是一次性的,每一次安装新的传感器,则需要手动的将传感器内的空气排干净,存在操作繁琐、固定不牢固、设备简陋的问题。
