Method and device for monitoring contraction activities of mother womb and controlling childbirth process

Abstract

A method and equipment for monitoring the uterine contraction of mother and controlling the delivery process features that an abdominal electrode including method is used to sample all abdominal signals including the noisese, such as mother ECG, fetal ECG and electromagnetic interference, and AGC module is designed for suppressing said noises, and a digital signal processor is used as the core unit to eliminate mother ECG. Its advantages are high reliability, no damage, and less distortion.

Description

technical field [0001] The invention relates to a medical and veterinary detection device and method, in particular to a method and a device for monitoring the uterine contraction activity of pregnant women and controlling the delivery process. Background technique [0002] A well-known method of monitoring the progress of a pregnant woman's labor is for the practitioner to feel the abdomen with his hands to estimate the strength of the contractions and the degree of descent of the uterus. The "normal" contractions after the actual labor begins are from the fundus to the cervix. advance. How a woman feels about her labor progress is also important. In addition, the degree of cervical dilation was estimated by endoscopy of the birth canal. However, the accuracy of this manual method of monitoring the progress of labor is directly related to the skill of the examiner. Furthermore, these conventional methods are discontinuous, making the patient uncomfortable, and any method...

Apparently, the diagnostic method of the delivery process fails to effectively grasp the uterine activity of the pregnant woman in the perinatal period (ie, the delivery state) and control the amount of oxytocin used to regulate the delivery process of the pregnant woman. In particular, the diagnostic device and method for the delivery process and Although the U.S. Patent No. 4,256,118 uses the method of externally induced abdominal electrodes to obtain abdominal electrical signals, it does not deal with the multiplicative noise interference in the abdominal electrical signals during the processing of the abdominal electrical signals, so that the obtained abdominal electrical signals The multiplicative noise cannot be effectively suppressed, therefore, the detected uterine myoelectric signal (IEMG) is severely distorted, which affects the validity and reliability of the final abdominal myoelectric signal, and the analysis of the two The frequency bands are relatively narrow. For example, the frequency band analyzed by US4256118 is 150-250Hz, and the frequency band analyzed by ZL93120192.6 is 0.01Hz-200Hz. The abdominal electrical signals in the high-frequency band are not considered, and the detected EMG and IEMG signals are only Contains local information but cannot reflect all the information of uterine contraction activity, so the reliability and accuracy of the analysis results are relatively low, which brings disadvantages to the subsequent analysis and judgment, and the two cannot be fed back through the final analysis results Control of labor progress, just general monitoring of labor progress
