Device and method for supervising birth process

Abstract

A labor process monitoring device, comprising: three ultrasonic sensors with transmitting and receiving functions arranged in a triangle, three ultrasonic sensors with receiving functions, a pressure sensor and a Doppler ultrasonic probe for measuring maternal cervical dilatation and fetal head position ; Ultrasonic signal drive and demodulation processing device; Calculation processing device; The present invention uses the ultrasonic triangle method to measure cervical dilation and fetal head position parameters, and automatically draws the cervical dilation curve, fetal head descending curve, fetal heart rate curve, and uterine pressure curve through calculation processing, and displays them on the same screen with time as a symbol Various curves, record and analyze and judge the continuous changes of the whole labor process, reliably and effectively assist doctors to monitor the whole process of fetal delivery in real time.

Description

technical field [0001] The invention relates to a labor monitoring device. Background technique [0002] Childbirth is a normal physiological process. Whether childbirth can be successfully completed depends on the coordination of labor force, birth canal, fetus, and mental and psychological factors. If one or several factors are abnormal, it will affect the progress of the labor process. It is sometimes difficult to determine the boundary between normal labor and dystocia during cephalic delivery, and the tendency of dystocia must be observed closely in order to detect the tendency of dystocia in time. The analysis of maternal mortality shows that about 65% of pregnant women die within 24 hours after delivery, including within 4 hours It accounts for about 50%, so it is necessary to use a scientific and practical monitoring method to monitor the labor process clinically, and the partogram is produced from this. The labor map includes two parts, the upper part is the labor ...

AI Technical Summary

Problems solved by technology

The dilation of the cervix is ​​done by inserting two fingers from the vagina into the uterus, spreading the fingers until they touch both sides of the external opening of the cervix, and then estimating the distance between the fingertips. In this way, even experienced people will have 0-2cm error

The measurement of the fetal head position is also achieved by palpation, so there is a very large error

At the same time, repeated vaginal testing for women with ruptured membranes will increase the incidence of infectious diseases - chorio (hair) amnionitis, and make the mother feel uncomfortable
