Background technique
Electronic fatal monitoring (electronic fetal monitoring, EFM) is used as a kind of assessment fetal in utero shape
The means of state have been widely used in whole nation midwifery medical institutions at different levels.The uterine contraction curve of mother's uterine pressure
The monitoring of (tocography, TOCO) is one of important parameter of EFM, and doctor passes through to fetal heart rate curve (fetal heart
Rate, FHR) and uterine contraction curve analysis, can find intrauterine fetal anoxia, in time to take further measures in time.
Electrometrogram (Electrohysterogram, EHG) can be from the non-invasive monitoring mesometrium of abdominal surface
Electrical activity, which is the spontaneous generation of physiology course in uterus, reflects uterotonic frequency, intensity etc..Study table
It is bright the mankind be pregnant 18 weeks when, so that it may measure uterine myoelectricity signal in body surface.
Pregnancy period uterine myoelectricity signal has important clinical meaning in foetus health monitoring, and power reflects uterus receipts
The intensity of contracting.
And the monitoring of existing uterine contraction there is once the shortcomings that, pressure probe need to be placed in palace bottom position and measure, different
The palace bottom position of pregnant woman is variant, and palace bottom position can also change as pregnant age increases, this just needs medical staff
Judged with experience abundant, it is complicated for operation.Pressure probe can generate an initial pressure and read when being fixed on her abdominal
Number, the reading as pressure reference, all make comparisons therewith by the pressure value measured later, it is seen that the uterine contraction pressure that this mode detects
It is a relative value, it cannot be said that bright intrauterine real pressure size.Movement, position chanP of pregnant woman etc. are easy to cause pressure to visit
Head be bonded not tight with her abdominal or generates position deviation, to monitored parameters mistake occur, causes to need when time guarding in vain
Again it guards, increases the workload of medical staff.Pressure probe needs to be fixed on abdomen by bandage, and comfort is poor, and easily hair
Raw probe-shift, influences measurement result.It can not identify uterine contraction type, cannot distinguish between true property uterine contraction and false uterine contraction.BMI(height
Body mass index-Body Mass Index, BMI is the index for measuring whole nutritional status) higher pregnant woman's measurement result compared with
Difference.Pregnant woman can not be monitored in process of production.
