无创测量大鼠等小动物的动脉压,是生物医学领域中清醒动物心血管功能研究必备的一项技术方法。国外于本世纪中期提出的尾套测压技术(tail-cuff technique)及研制的脉搏描记器(sphygmograph)已被有关研究工作者广泛采用。该仪器可准确测量大鼠收缩压,但不能测量舒张压的精确数值。为了取代这种昂贵的进口仪器(tail-cuff sphygmograph),并解决舒张压的无创准确测量问题,我们参照尾套技术的原理,设计制作了一种清醒大鼠尾动脉压测量 Noninvasive measurement of arterial pressure in small animals, such as rats, is an essential technique in the study of cardiovascular function in conscious animals in the biomedical field. The tail-cuff technique and the developed sphygmograph proposed by foreign countries in the middle of this century have been widely used by researchers. The instrument accurately measures systolic pressure in rats but does not measure the exact value of diastolic pressure. In order to replace this expensive tail-cuff sphygmograph and solve the noninvasive and accurate measurement of diastolic pressure, we designed a rat tail arterial pressure measurement
