What is a home fetal heart? It is understood that home fetal heart is mainly detected by ultrasonic detection technology, and its function is to reflect the condition of the fetus in the mother by monitoring fetal movement and fetal heart. Too fast or too slow fetal heart rate is a problem, and the data on fetal heart rate can roughly judge the health status of fetus.
The principle of self-made fetal heart:
Doppler effect is an important physical phenomenon of ultrasound. When continuous wave ultrasonic waves are emitted, when there is relative motion between the sound source and the measured object, Doppler effect will occur. When the moving target moves to the sound source, the wavelength of the reflected wave is compressed, so the frequency increases; On the contrary, when the target is far away from the sound source, the wavelength of the reflected wave becomes longer, so the frequency decreases in unit time.
Advantages of home fetal heart:
Doppler technology is used in obstetrics and gynecology, which can check and diagnose the heartbeat of heart and valve, blood flow and fetal heart beat. Because it is safe and harmless to pregnant women and fetuses, it can be checked repeatedly, diagnosed accurately and used conveniently, so it is widely used.
Is it necessary for buyers to use fetal heart? Recently, many novice expectant mothers have consulted Mama.com: Is it necessary for buyers to use fetal heart?

Is it necessary to buy a fetal heart? Experienced mothers' answers tend to be "unnecessary".
Ma Bao lovely baby: I don't think it's necessary to buy it. It's useless. You can feel it when the baby moves. As long as your husband puts his head close to your stomach, he will obviously feel it when the baby moves. Besides, I will go for a checkup every month, so there is nothing to worry about.
Ma Bao Douma: It's not necessary, as long as you have a good prenatal examination on time. And I don't think there's anything abnormal. It's really unnecessary. I don't know if there is radiation, but a small amount of it will definitely not have much impact on the baby and you. You will also touch the mobile phone, TV and computer every day, so don't do it often.
In addition, experts say that listening to fetal sounds at home will generally not affect the baby, and prospective parents can decide whether to buy fetal heart according to their own needs. However, the fetus in early pregnancy is in the stage of organ differentiation, so it is necessary to strictly grasp the indications of fetal heart desire. It is not recommended to use home fetal heart rate for self-monitoring before 15 weeks of pregnancy. /kloc-it is safe for pregnant women who are pregnant after 0/5-28 weeks to listen to it three times a day, each time 1 minute.

Matters needing attention in using home fetal heart rate. As the name implies, home fetal heart rate is an electronic instrument used for fetal heart monitoring at home. It is not as familiar as TV, radio, electric fan and other common appliances. For the smooth birth of the baby, the expectant mother has done her best. The following are the precautions you must know when using home fetal heart.
1, pregnant women lie flat at home for home monitoring, which means that pregnant women are examined in the hospital, doctors make Doppler diagnosis or auscultation of fetal heart sounds for pregnant women, and put the voice of angels probe near the position where doctors hear fetal heart sounds during examination to find the fetal heart.
2, pregnant women at home in a sitting position, semi-lying position for family monitoring, refer to the hospital pregnant women, doctors do Doppler diagnosis for pregnant women or auscultation of fetal heart sounds, put the voice of angels probe near the slightly lower position where the doctor heard the fetal heart during the examination, and find the fetal heart.
3, the "tick" sound of fetal heart audio-visual clocks is faster. The unit of calculation is 1 minute, and the normal time per minute is 120- 160 times. Too fast or too slow is not normal, especially slow means that the fetus is seriously hypoxic, and pregnant women need to be sent to hospital for treatment.
4. Don't treat the maternal abdominal artery pulse sound as fetal heart sound. If it is difficult to distinguish, you can feel the maternal pulse while listening to the fetal heart sound. If the sound you hear is consistent with the pulse, it is the blood vessel pulse sound of the parturient.
5. Several possibilities of using angel voice to monitor obstacles: Please check whether the battery needs to be replaced, whether the switch is turned on, whether the volume is appropriate, whether the plug is plugged in, and whether the probe is coated with coupling agent or water or oil.
