Antenatal training device and fetus-voice meter integrated machine

Abstract

The invention provides an antenatal training device and fetus-voice meter integrated machine. The machine comprises a fetal heart signal acquisition device and a fetal heart signal extraction device, wherein the fetal heart signal acquisition device is used for sending out antenatal training voice signals and acquiring heartbeat sound signals sent out from the body of a pregnant woman at an interval of the antenatal training voice signals; the fetal heart signal extraction device receives the heartbeat sound signals acquired by the fetal heart signal acquisition device and separating fetal heart signals from the heartbeat sound signals, and the separated fetal heart signals are sent to a background server to be analyzed or displayed and primarily diagnosed at the local end; the fetal heart signal acquisition device adopts a bone conduction microphone and receives the heartbeat sound signals passively. The machine can monitor the heartbeat of a fetus while performing antenatal training on the fetus, acquires the fetal heart signals through the bone conduction microphone, cannot harm human bodies due to the fact that the fetal heart signals are received passively in the whole acquisition process and is safe and high in practicability.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an all-in-one fetal education device and fetal heart monitor. Background technique [0002] Fetal monitoring is an important means to ensure the safety of perinatal pregnant women and fetuses and to achieve eugenics. After the pregnant woman enters the state of waiting for labor, the commonly used methods of fetal monitoring are: ultrasonic Doppler fetal monitoring and fetal monitoring, both of which function through the detection of fetal heart activity during pregnancy, early detection of abnormal conditions in the process of fetal growth and development, and Take corresponding medical measures in time for prenatal treatment to reduce the birth defect rate and mortality rate of fetuses. The limitations of these two methods are: due to fetal movement, it is difficult to implement without the presence of a doctor; frequent use has an impact on the health of the fetus; only feta...

AI Technical Summary

Problems solved by technology

The limitations of these two methods are: due to fetal movement, it is difficult to implement without the presence of doctors; frequent use has an impact on the health of the fetus; only fetal heart rate can be detected, and waveform information like fetal electrocardiogram cannot be obtained.

[0003] The existing fetal ECG monitoring system detects it through ultrasound, and there will still be a certain amount of radiation. If regular detection is practical, it will inevitably cause certain damage to the health of the fetus.
