Description

心输出量自动测量系统 技术领域
本发明是关于一种心输出量测量系统，尤其是关于一种采用热稀释法的心输出量测量系统。
 背景技术
临床上广泛采用的监测心输出量的方法是热稀释法。热稀释法是将漂浮导管经右心房插入肺动脉，然后经该导管向右心房注入冷生理盐水，该导管的前端放置有温度传感器，当该冷生理盐水与血液混合后发生温度变化，混合后的血液进入肺动脉时，将被温度传感器感知，根据冷生理盐水注入的时刻和混合后温度的变化情况，分析心输出量。
采用热稀释法时，由于血液和冷生理盐水在右心房混合，而在肺动脉处(即漂浮导管前端)测量血液和冷生理盐水混合后的温度变化，进而测量心脏射血的能力。在混合的同时，心脏也在射血，整个测量过程是一个动态的过程，所以注射速度和均匀性会直接影响冰生理盐水和血液的混合的充分性，因此对心输出量的测量结果有直接的影响。
在现有的心输出量测量系统中，通常由医护人员手工进行冷生理盐水的注射，而冷生理盐水的注射速度的快慢和均匀性以及注射的间隔和频度完全取决于医护人员的经验，因此现有心输出量测量技术具有以下缺点：1）临床医护人员的注射经验会直接影响心输出量测量结果；2）临床医护人员不恰当的注射有可能损伤病人的心脏机能。

输出量测量装置启动测量或停止测量。

定的时间内血温变化超过一定阈值时，自动进行心输出量测量。较低温度的冷液体和较高温度的血液混合后，血温有一个变化范围，该范围可以通过多次实验统计得出，当检测到血温变化处于该范围时，即可以认为系统已经进入测量状态，此时，心输出量测量装置即可以根据血温变化进行心输出量测量。

行保护计时，在保护计时结束前，所述主控装置使所述液体注射装置保持在停止注射状态。
