Description

有创血压检测装置及检测系统 技术领域
本发明涉及的是一种医学诊断设备领域的技术，具体是一种有创血压检测装置及检测系统。
背景技术
有创血压(IBP)一般可监测：动脉血压(ABP)、中心静脉压(CVP)、肺动脉压(PAP)、左房压(LAP)、颅内压(ICP)。其测量原理是：首先通过穿刺将导管置于被测部位的血管内，导管的外端直接与压力传感器相连接，由于流体具有压力传递作用，血管内的压力将通过导管内的液体传递到外部的压力传感器上，从而可获得血管内实时压力变化的动态波形，通过特定的计算方法，可获得被测部位血管的收缩压、舒张压和平均动脉压。临床工作中有创血压已成为危重病人血液动力学监测的主要手段，它可以及时和准确的监测病人的血压变化。
压力传感器的高度会影响压力的测量，在进行有创血压监测过程中，按照测量要求需保持压力传感器与心脏在同一水平上，并要牢固固定连接压力传感器的导管，防止导管位置移动或脱出，否则会影响有创血压的测量值，进而影响患者的精准治疗。目前临床工作中主要采用胶布将压力传感器以及连接导管粘贴床头或者粘贴到输液杆上，对压力传感器的位置进行固定定位。另外中国专利文献号为CN208274565U的实用新型专利公开了一种可精准定位的压力传感器固定装置，通过设置固定架和调节架对压力传感器和激光发射器的位置进行固定和调节，通过激光发射器定位使得压力传感器能够与患者心脏处于同一水平面，较现有技术做出了较大的改进。但是上述方式均无法满足手术的需求，无法在手术中根据需要及时确定心脏的高度位置，以保证有创血压监测的持续性和稳定性。
