TJ—I 型超声多普勒胎儿监护仪是清华大学电力系、河北省定兴电子仪器厂、上海纺织第二医院和北京医学院附属第三医院联合研制的。该仪器应用超声多普勒效应对胎儿心率进行瞬时检测,具有声光显示和电表直读指示。并能测定宫缩强度,可与胎心率同时进行描记。若胎心率超过正常范围,仪器能自动报警,为进一步提高产科医疗水平,降低胎婴死亡率提供了新的辅助诊断方法。由于采用了广角发射换能器,特殊设计
TJ-I ultrasonic Doppler fetal monitor is the Department of Electric Power Tsinghua University, Hebei Dingxing electronic equipment factory, Shanghai Textile Second Hospital and Beijing Medical College Hospital affiliated to the joint development. The instrument uses ultrasound Doppler effect of fetal heart rate for instantaneous detection, with sound and light display and meter direct reading instructions. And can determine the intensity of contractions, fetal heart rate can be traced at the same time. If the fetal heart rate exceeds the normal range, the instrument can automatically alarm to provide a new diagnostic method to further improve obstetric care and reduce infant mortality. Due to the wide-angle launch transducer, a special design
