Description
Technical field
It the utility model is related to mother and baby's monitoring technology field, especially a kind of movement of the foetus, uterine contraction intelligent monitor system.
Background technology
Mainly include the detection of fetus Fetal Heart Rate and movement of the foetus number for the health supervision content of mother and baby both at home and abroad.
The detection of fetus Fetal Heart Rate is realized using principle of Doppler more, and fetus is obtained using doppler ultrasound
Cardiechema signals, and calculate fetal heart frequency according to cardiechema signals so as to judge the health status of fetus.But doppler ultrasound
The problem of one radiation intensity of generally existing, although detection limit is very low, falls within and damage detection category, can be right if control is bad
Baby causes certain injury, is not suitable for regular, repeated inspection and long-time family uses.In addition, pregnant woman makes
With needing effectively measure fetal heart frequency by couplant during doppler ultrasound, Consumer's Experience is bad.Fetus
The monitoring of movement of the foetus does not have ripe product in the whole world.At present, most of doctor recommends pregnant woman to take the method oneself counted
Record movement of the foetus.This needs perception manual count of the pregnant woman for a long time according to belly, caused by both unavoidable pregnant woman perceives power
Count and omit, increase is also counted caused by the action noise of unavoidable stomach etc., this mode wastes time and energy, and has one
Subjective feeling brings error in judgement problem, tends not to obtain accurate conclusion, easily causes erroneous judgement.And family expenses doppler ultrasound
Device function is relatively simple, is only capable of meeting simple rate calculation, can not then be caught automatically for Fetal Movement Signal, it is difficult to fetus
A comprehensive, reliable health state evaluation and feedback of the information are made after particularly 30 weeks.
The expected date of childbirth can be predicted according to uterine contraction pressure condition, all rarely have always to the monitoring in terms of pregnant woman's uterine contraction and grind
Study carefully.
