Automatic counting device for fetal movement

Abstract

The invention discloses an automatic counting device for fetal movement, including the host, sensor, belt, and wireless receiver. The described host consists of the circuit board, battery, power switch, wireless transmitter module, low-voltage indicator light and working state indicator light; the described sensor is composed of the pressure sensor and sensor wire; the described wireless receiver consists of the wireless receiving module, display, sound alarm circuit, optical alarm circuit, batteries, and power switch; the described pressure sensor connects the host via the sensor wire; the described host transfers data to the wireless receiver via the wireless signal transmission method. The invention has small size, which is easy to carry. It can automatically record the number of fetal movement with objective and accurate result. When any abnormal fetal movement occurs, it will give an alarm immediately so that pregnant women can accept medical treatment timely, greatly reducing the risk of fetal death.

Description

technical field [0001] The invention relates to a medical device, in particular to an automatic fetal movement counting device for detecting and recording fetal movements. Background technique [0002] After 4 months of pregnancy, that is, from the 5th month, the mother can obviously feel the movement of the fetus. The fetus reaches out, kicks, and hits the uterine wall in the uterus. This is fetal movement. The number, speed, and strength of fetal movement indicate the safety of the fetus. Normal obvious fetal movement is no less than 3-5 times in 1 hour, and the number of obvious fetal movement in 12 hours is more than 30-40 times. However, due to the large individual differences of fetuses, some fetuses can move about 100 times in 12 hours. As long as the fetal movement is regular and rhythmic, with little change, it proves that the fetal development is normal. Normal fetal movement means that the placenta is functioning well, the oxygen delivered to the fetus is suffic...

Problems solved by technology

[0005] At present, the method of detecting fetal movement mainly relies on counting by pregnant women themselves, which is highly subjective, and the counting is inaccurate and unreliable
