Electronic partogram system based on magnetic field tracing and positioning technology

Abstract

The invention discloses an electronic partogram system and a parameter calculating method based on a magnetic field tracing and positioning technology. The electronic partogram system comprises a magnetic field tracing and positioning module, an ultrasonic image module, a fetal heart rate and uterus shrink pressure module and an electronic partogram workstation. The magnetic field tracing and positioning module comprises a magnetic field generation device for generating a magnetic field and a magnetic induction sensor. According to the invention, through monitoring parameters such as a fetal head position, a fetal head direction, cervical dilatation, a fetal heart rate, uterus shrink pressure in a delivery process, an electronic partogram can be full-automatically or semi-automatically generated on a measuring time point, so that a doctor can dynamically monitor the delivery process through the electronic partogram. Simultaneously, due to the utilization of a full-automatic parameter calculating operation mode and a semi-automatic parameter calculating operation mode, through monitoring fetal head parameters and pelvis parameters, pelvic disproportion can be forecasted on the measuring time point; and through monitoring the fetal heart rate and the uterus shrink pressure of a mother / a fetus, multi-parameter monitoring is realized.

Description

technical field [0001] The invention relates to the monitoring technology of pregnant women and fetuses during childbirth, in particular to an electronic parturography system based on magnetic field tracking and positioning technology and a method for measuring and calculating characteristic parameters. Background technique [0002] There are many factors affecting the quality of the birth population, the perinatal period is the main reason (accounting for 70% to 80%), and the delivery process (labor process) is the most critical. The gestation period is 10 months, the postpartum upbringing is more than 10 years or longer, and the delivery period is very short, only a few hours, or even tens of minutes or even a few minutes. The short delivery period seriously affects the intelligence and health of the child after birth, and plays a very important role in eugenics. Therefore, the childbirth process is a critical moment that cannot be ignored. If the role of electronic moni...

Problems solved by technology

[0004] At present, the labor map is drawn manually in clinical practice, and there are serious problems of accuracy and reliability.

In clinical practice, midwives / obstetricians usually use digital vaginal examination to estimate the fetal head position, fetal position, cervical dilatation and thinning degree to determine the labor process, but there are the following problems: 1) High subjectivity and poor objectivity , the doctor’s labor intensity is high; 2) Inaccurate estimation of fetal head position: indirect estimation of fetal head position, deformation and formation of fetal head may cause misleading; 3) Inaccurate estimation of fetal position: 30%-60% of vaginal examinations cannot be accurately determined Fetal position; 4) Inaccurate estimation of cervical dilation: Even among experienced doctors, the estimation difference is as high as 1-2cm

[0006] The devices or methods for monitoring the progress of childbirth disclosed in the above-mentioned patents are all measurement methods or systems for the two parameters of cervical dilatation and fetal head position, rather than electronic partogram systems that can provide intuitive evidence for obstetricians
