Device and method for collecting fetal movement of pregnant woman through non-contact micro-motion sensor

Abstract

The invention discloses a device and a method for acquiring fetal movement of a pregnant woman by a non-contact micro-motion sensor, which are applied to the technical field of human physiological signal acquisition and comprise a pad body, a micro-motion sensing acquisition module, a signal preprocessing module, a signal transmission module, a central processing unit and terminal equipment. The micro-motion sensing measurement device is arranged in the pad body, direct contact with the skin of a pregnant woman is avoided, and the comfort degree of the pregnant woman in the measurement process is improved; the fetal movement occurrence position and the fetal movement occurrence time are calculated and obtained in a multi-point asynchronous mode, fetal movement measurement can be more accurate, and the value of obtained data for follow-up medical reference utilization is higher.

Description

technical field [0001] The invention relates to the technical field of human physiological signal collection, in particular to a device and method for collecting fetal movement of a pregnant woman with a non-contact micro-motion sensor. Background technique [0002] Fetal movement, uterine contraction and fetal heart rate are very important physiological parameters to observe the condition of the fetus during a woman's pregnancy cycle. Fetal movement refers to the activity of the fetus in the uterus. heart rate. Among them, fetal movement is the earliest and easiest signal to detect, and it is also the method most often recommended by clinicians to pregnant women to observe whether the fetus is healthy. [0003] The prior art includes: a way for pregnant women to self-measure fetal movement, a single-channel measuring device and a multi-channel measuring device. Among them, the method of self-measurement of fetal movement by pregnant women is quite lengthy. For example, wh...

Problems solved by technology

Such a counting method is not easy for pregnant women. Not only is it susceptible to subjective influence, but it is also difficult to implement daily calculations for such a long time; the single-channel measurement device does not have a multi-point measurement design, and electrode patches are required. Attached to the skin of pregnant women to detect EMG signals, it is easy to cause discomfort to pregnant women when worn, and is easily disturbed, and it is impossible to judge the location of each fetal movement; the multi-channel measurement device is still attached to the Pregnant women's skin is used to detect EMG signals, so there are still situations where it is easy to cause discomfort and interference to pregnant women.
