Method of Use
1.Pregnant women should stay in a good mood and adopt a flat or supine position
2.The probe is coated with a uniform coupling agent and then turned on the stomach, and the probe is used to find the position of the fetal heart.
3.Determine the approximate position of the fetal heart rate according to the corresponding cycle, close the probe to the belly, and press slightly hard for more than 5 seconds before moving to the next point to listen to the baby's fetal heart sound
4.When you hear a "click" sound like a horse's hoof, it is the baby's fetal heart sound, which is monitored within 1-3 minutes, and the fetal heart rate number between 120-160 is normal
Tips :
1. When measuring, pregnant mothers should lie flat or semi-reclining, maintain a good mood, measure in a quieter environment, move as little as possible, and stay away from electrical interference.
2. After hearing the baby's stable and continuous fetal heart sound, stand still for 3-5 seconds, so that the fetal heart rate probe receives a stable and continuous fetal heart signal, and the value displayed at this time is the accurate fetal heart rate. Note that the value at this time is not static, but will fluctuate slightly. In the process of finding the fetal heart, the movement should be slow, the amplitude should not be too large, and press a little harder.
