Problems solved by technology

However, for pregnant women in ordinary families, the traditional fetal heart rate stethoscope has low sound and large external interference. It is difficult for pregnant women to judge the position of the fetus through the fetal heart rate stethoscope, and it is even more difficult to clearly hear the fetal heart sound signal of the fetus through the fetal heart rate stethoscope. It is also impossible to judge whether the fetal heart sounds are normal

Embodiment

[0028] Such as figure 1 , figure 2 and image 3 As shown, the wearable fetal heart sound monitor disclosed by the present invention is mainly composed of a cavity type abdominal belt, a stethoscope probe, a sound sensor, a signal processing circuit and a handheld mobile terminal. Among them, the abdominal belt is used as the main carrier to carry the stethoscope probe, sound sensor and signal processing circuit; the stethoscope probe is used to collect the vibration signal caused by the fetal heartbeat changes in the pregnant woman's abdomen, and perform preliminary amplification, and the sound sensor is based on the signal collected by the stethoscope probe. The vibration signal transmits the sound signal to the back-end circuit, that is, the fetal heart sound signal. After the signal processing circuit processes the fetal heart sound signal, it transmits it to the handheld mobile terminal for display. The displayed result can be the number of vibrations and the frequency o...

Abstract

The invention discloses a wearing-type fetal heart sound monitoring instrument based on a multi-angle stethoscope array. The wearing-type fetal heart sound monitoring instrument comprises a cavity-type bellyband, a sound monitoring array fixed on the back surface of the cavity-type bellyband and used for monitoring fetal heart sound, a signal processing circuit arranged in an inner cavity of the cavity-type bellyband and a handheld mobile terminal arranged outside the cavity-type bellyband and wirelessly connected with the signal processing circuit. The wearing-type fetal heart sound monitoring instrument is ingenious in design, simple in structure, safe and convenient to operate, capable of easily collecting and displaying the fetal heat sound in a pregnant woman body and relatively high in practical value.

Description

technical field [0001] The invention relates to a fetal heart sound monitoring device, in particular to a wearable fetal heart sound monitor based on a multi-angle stethoscope array. Background technique [0002] Fetal heart sound is the heartbeat of the fetus. At 18-20 weeks of pregnancy, fetal heart sounds can be heard through the pregnant woman's abdomen, which is double-tone, like the "tick" sound of a clock. The fetal heart is an important organ that provides oxygen and nutrients to the fetal body. Its activities are not only directly or indirectly regulated by blood movement and hormones and other body fluids, but also controlled by the central nervous system—the brain, all of which are reflected in the fetal heart rate. sound and the rhythm of fetal heart sounds. Therefore, the collection and monitoring of fetal heart sounds is of great significance for doctors and pregnant women to keep abreast of the growth and development of the fetus, discover possible hidden di...
