Bellyband type fetal movement monitor

Abstract

The invention discloses a bellyband type fetal movement monitor. The bellyband type fetal movement monitor comprises a capacitive sensor array, a bellyband, a signal processing circuit and a handheld mobile terminal, wherein the capacitive sensor array is constructed by metal interlayers and insulating layers in a matching way; the bellyband is connected to the two ends of the capacitive sensor array; the signal processing circuit is used for processing the capacitive change of the capacitive sensor array; the handheld mobile terminal is wirelessly connected with the signal processing circuit; the signal processing circuit is embedded into the bellyband. The bellyband type fetal movement monitor is simple in structure, is convenient to operate, is safe and reliable, has no side effect, can be used for accurately monitoring the fetal movement of a pregnant woman for a long time, and has very high practical value and market prospect.

Description

technical field [0001] The invention relates to a monitor, in particular to an abdominal belt type fetal movement monitor. Background technique [0002] Fetal movement refers to the movement of the fetus in the mother's uterine cavity against the uterine wall. After 4 months of pregnancy, that is, from the 5th month, the mother can clearly feel the movement of the fetus. The fetus reaches out, kicks, and hits the uterine wall in the womb. This is fetal movement. [0003] Fetal movements are a sign of life in the womb. The number, speed, and strength of fetal movement show the health status of the fetus. Observation of fetal movement in early pregnancy is helpful for estimating the situation in late pregnancy. According to reports, at 7 weeks of pregnancy, the abortion rate of those with fetal movement is only 3%, while the abortion rate of those without fetal movement is as high as 98%. In cases where no fetal movement can be seen at 9 weeks of gestation, miscarriage is ...
