Uterus shrinkage laplacian relief map instrument

Abstract

The invention discloses a uterine contraction Laplace topography instrument, which is composed of a plurality of Laplace electrodes integrated with bioelectrical amplifiers and filter circuits, an analog-to-digital converter, a microprocessor system and a display connected in sequence, and the micro The processor system is also connected with a man-machine dialogue device. Multiple electrodes are placed in the abdomen of the parturient, and the uterine myoelectric Laplace signal of the parturient is picked up, amplified and filtered, and then input to the analog / digital converter. The converted digital signal is processed by the microprocessor system and can be processed by the plane Display on monitor and print on printer. The uterine contraction Laplace topography instrument of the present invention can not only detect the pacemaker activity of each part of the puerpera's uterus in real time, but also reflect the contraction sequence, phase and direction of each part of the puerpera's uterus, so as to diagnose whether the labor force is normal or not. It provides a scientific basis and provides a new method for avoiding dystocia, guaranteeing the natural delivery of mothers and the safety of mothers and babies.

Description

technical field [0001] The invention belongs to a medical instrument, in particular to an instrument for detecting and displaying the strength and direction of uterine contraction in a puerpera during childbirth. Background technique [0002] There are three main reasons for maternal dystocia during childbirth: abnormal fetus, abnormal birth canal and abnormal labor force. The first two reasons are easy to detect before delivery. For primiparous women, the third reason can only be diagnosed during labor, but there is no instrument or means to detect it. Doctors only rely on experience to judge, without objective indicators, it is difficult to make an accurate diagnosis, and they cannot effectively guarantee the safety of mothers and babies. [0003] Uterine muscle is a kind of smooth muscle, which is different from skeletal muscle, and the frequency and mode of transmission of the two are very different. Although some people use ordinary electr...

AI Technical Summary

Problems solved by technology

Although some people use ordinary electromyography machines to study uterine myoelectricity, the frequency band and gain of ordinary electromyography machines are not suitable for the measurement of uterine myoelectricity, and the display and recording methods of ordinary electromyography machines are one-dimensional. In the form of waveform, it is difficult to express the direction of uterine muscle contraction and the phase of contraction of each part
