Important Tool for Pregnant Women

Unlike other heartbeat monitors, this one is portable and easy to use. You can use earphones on this device so you can listen to your baby even when you are on the road.

Aside from connecting with your baby, it is also important to constantly monitor your baby’s health. In the third trimester, women are advised to count the baby’s kicks. As the baby moves to position themselves for childbirth, babies are at risk of choking on their own cord. Moreover, this product can detect heartbeat for as early as 10-weeks in the pregnancy.

In general, the position of fetal heart with small gestational age is at the lower 1/3 of the pubis-umbilicus line.
The position moves upward with the increase of gestational age and the position inclines left or right with the differences of the fetal position. Since a fetus moves in the body, it may cause a wide range of movement for the position of the fetal heart. Therefore, the careful operation is needed to find the accurate position of the fetal heart.

In the case of the moving probe, it is required to make sure that there is enough coupling agent between the surface of the probe and the abdomen of pregnant women. If the coupling agent is not enough, it may be impossible to hear fetal heart sounds or the heard fetal heart sounds are not clear, which affects the accuracy of the calculation.
