It is better to record fetal heart sounds in the following three periods


  • The position of fetal heart sound varies in different time periods


Fetal heart rate comparison table

Normal fetal heart rate: 120~160 beats/minute


Usage Method

1. Long press power button for 2s to start up.

2. Adjust volume

3.Wipe coupling agent on the probe

4. Close to the fetal heart to measure


Warm tips:

1. Before 16 weeks of pregnancy, the fetal heart sound is weak. It is recommended that the pregnant mother be measured in the morning with an empty stomach.

2. After 32 weeks, the fetus is likely to enter an unexpected period, when it is likely to suffer from hypoxic umbilical cord around the neck, etc., which needs to be tested every day.


1. What is fetal heart sound ?

The fetal heart is sound like small train “Hong,hong,hong”with rhythm.

2 .Does the coupling agent has any effect on the baby, what effect and how to use it?

a. The coupling agent is composed of water-soluble polymer material, pure water and viscosifier. It is non-toxic and non-corrosive, and will not harm the fetus. However, it should be kept away from children to avoid accidental ingestion.

b. The coupling agent eliminates the air between the belly and the probe, making the sound of the fetal heart sound clearer, and can be replaced by water and olive oil if there is no coupling agent in late pregnancy.

c. Apply the coupling agent evenly on the probe and gently press the belly.

3.How often to detect, and whether it will affect children if use more often?”

According to the recommendations in the manual, all indicators such as ultrasonic output strength of the equipment conform to the industry standards, and it is safe to carry out daily fetal heart monitoring.

4.Why is there noise when measuring?

During the measurement process, the movement of the fetus and probe will generate noise. At the same time, if the user does not find the position of the placenta, the umbilical cord blood flow and other factors will also lead to noise.The patient needs to find the placental position before monitoring the fetal heart sound.

5.How to clean and disinfect instruments?

a. Turn off the device and remove the battery before cleaning and disinfecting。

b. Each time after listening to the fetal heart, the probe can be cleaned with dry cloth or tissue or a small amount of medical alcohol can be used for cleaning disinfection。

c. The surface of the instrument can be cleaned with a non-corrosive cleaner. Do not disinfect at high temperature or use a corrosive cleaner for cleaning.

    Product is in perfect condition and seller shipped the product fast. Item received in 12 days. The heartbeat can be heard but the sound is slightly quiet but much clear with a headset. The heart rate however that is shown in display seems inaccurate. That’s not a problem for me though. Just need to hear the heartbeat <3
