specific Embodiment approach

[0040] refer to figure 2 , in step S20, a specific implementation manner of processing the acquired uterine muscle contraction mechanical pressure signal to obtain the uterine mechanical pressure value includes:

[0041] Step S201 , performing signal envelope processing on the uterine muscle contraction mechanical pressure signal to obtain a uterine mechanical pressure envelope signal.

[0042] Specifically, a preset low-pass filter can be used to process the mechanical pressure signal of uterine muscle contraction, which can eliminate noise in the mechanical pressure signal of uterine muscle contraction and achieve a denoising effect.

[0043] Step S202 , dividing the obtained uterine mechanical pressure envelope signal by the envelope value corresponding to the preset pressure value to obtain the uterine mechanical pressure value.

[0044] refer to image 3 , in step S30, a specific implementation manner of processing the acquired uterine muscle electrical signal to obtai...

Abstract

The invention discloses a method and a device for monitoring maternal uterine contraction activity. The method comprises: acquiring the uterine muscle contraction mechanical pressure signal and uterine muscle electrical signal of the maternal uterus in real time; processing the acquired uterine muscle contraction mechanical pressure signal to obtain Uterine mechanical pressure value; the obtained uterine muscle electrical signal is processed to obtain the uterine electrical pressure value; according to the obtained uterine mechanical pressure value and uterine electrical pressure value, the uterine contraction pressure curve is drawn. By acquiring the uterine contraction pressure signal and uterine muscle electrical signal of pregnant women in real time, and calculating the uterine mechanical pressure value and the uterine electric pressure value respectively, and then comparing the two pressure values, the uterine contraction pressure curve is drawn; The strength of uterine muscle contraction and the electrical activity of uterine muscle are calculated, so medical staff can intuitively see the real state of uterine muscle contraction, so as to guide them to take corrective measures and reduce the risk of medical accidents.

Description

technical field [0001] The invention relates to the technical field of maternal-fetal monitoring, in particular to a method and a device for monitoring maternal uterine contraction activity. Background technique [0002] Clinical studies have shown that the production of maternal uterine contractions is caused by the electrical activity of uterine muscle. When uterine smooth muscle cells are excited, action potentials are generated. The action potentials rapidly propagate through low-resistance channels between adjacent cells, causing numerous uterine muscle cells to synchronously excited and contract. This leads to changes in uterine contraction pressure, abdominal wall diameter and tension, and contraction pain, which means that uterine muscle contractions are the result of electrical activity in the uterine muscle. [0003] At present, clinically, the strength of the uterine muscle contraction of the puerpera is detected by the external uterine contraction pressure sensor...
