The heartbeat sensor circuit diagram comprises a light detector and a bright red LED. The LED needs to be of super-bright intensity because maximum light passes and spreads if a finger placed on the LED is detected by the detector.
HBTJY 1/1A/2/2A Infant Fetal Heartbeat Detector Brief Introduction:
1.Digital HBTJY-series Ultrasonic Doppler Fetal Heart Detector is applied to examine the fetus, its movement and its blood circulation on the principle of Doppler effect.
2.The instrument is very important to the diagnosis of early stage gestation and the development of fetus, and it is able to detect the fetal rhythm, the sound of fetal blood flow or umbilical blood flow, the pulse of uterus artery and twin fetus.
3.There is neither damage nor pain in gravidity during the examination, it is simple to operate; rapid to response and good in repeat.
