离体心脏灌流是动物实验中常用的一种方法,用来研究冠脉循环颇为便利。过去用小量筒测量冠脉流出液,误差较大,又得不到客观记录。我组在目前换能器缺乏、设备简陋的条件下,根据我们实验的需要组装了一套能客观描记离体灌流心脏冠脉流量、心率及心收缩强度的实验装置,实践表明还是比较合用的。 Isolated cardiac perfusion is a commonly used method in animal experiments to study the coronary circulation is quite convenient. In the past with a small measuring tube coronary effluent, the error is larger, but not objective records. My group in the current lack of transducers, equipment, crude conditions, according to our experimental need to assemble an objective description of perfusion heart coronary flow, heart rate and cardiac contractility experimental device, practice shows that it is more useful .
