Method and device for monitoring maternal uterine contraction activity

Abstract

The invention discloses a method and a device for monitoring a maternal uterine contraction activity. The method includes the steps that a uterine muscle contraction mechanical pressure signal and a uterine muscle electrical signal of a maternal womb are obtained in real time; the obtained uterine muscle contraction mechanical pressure signal is processed to obtain a uterine mechanical pressure value; the obtained uterine muscle electrical signal is processed to obtain a uterine electrical pressure value; and according to the obtained uterine mechanical pressure value and the uterine electrical pressure value, a uterine contraction pressure curve is drawn. By obtaining the uterine contraction pressure signal and the uterine muscle electrical signal of pregnant women in real time, the uterine mechanical pressure value and the uterine electrical pressure value are calculated respectively, and then the two pressure values are compared to draw the uterine contraction pressure curve; and due to the fact that the two pressure values respectively reflect uterine muscle contraction intensity and uterine muscle electrical activity intensity, medical personnel can intuitively see the true state of uterine muscle contraction to guide the medical personnel to correctly make corresponding disposal measures, and the risk of medical negligence is lowered.

Description

technical field [0001] The invention relates to the technical field of maternal-fetal monitoring, in particular to a method and device for monitoring maternal uterine contraction activity. Background technique [0002] Clinical studies have shown that maternal uterine contraction is caused by the electrical activity of uterine muscles. When uterine smooth muscle cells are excited, action potentials are generated. Action potentials spread rapidly through low-resistance channels between adjacent cells, causing countless uterine muscle cells to excite and contract synchronously. In turn, it will cause changes in maternal uterine contraction pressure, changes in abdominal wall diameter and tension, and contraction pain. That is to say, uterine muscle contraction is the result of uterine muscle electrical activity. [0003] At present, clinically, the contraction strength of maternal uterine muscles is detected by the external uterine contraction pressure sensor placed in the are...
