Embodiment Construction

[0096] The traditional fetal position identification method is that doctors use their experience to judge the fetal position by touching the mother's abdomen. If it is more advanced, ultrasound contrast can be used to identify the fetal position.

[0097] In the present invention, a group of physiological electrode patches is pasted around the abdomen of the mother, and the fetal position and fetal movement can be identified through the signal processing of the previous stage and the algorithm of the subsequent stage. Physiological electrode patch sensing technology uses low-cost hardware production costs. After low-noise pre-stage signal processing, the subsequent stage further separates and processes the signals to obtain the mother's uterine contraction and ECG signals, and fetal signals. ECG signals, using these signals and some recognition algorithms, you can get the fetal position, fetal movement, fetal heart rate and mother's uterine contractions and heart rate. With th...

Abstract

The invention discloses a maternal fetus monitoring device and a maternal fetus monitoring method. A fetal position and fetal movement monitoring device comprises a group of patch electrodes, a preceding-stage signal processor, a post-stage signal processor and a fetal position judgment processor, wherein the patch electrodes are used for being attached to a maternal abdomen to provide the measuration of at least three channels; the preceding-stage signal processor receives a plurality of induction signals of the group of patch electrodes, inhibits noise and amplifies the signals to output a group of characteristic induction signals; the post-stage signal processor receives the group of characteristic induction signals outputted by the preceding-stage signal processor so as to separate maternal electrocardio-complex waves and fetal electrocardio-complex waves which correspond to the channels; and the fetal position judgment processor analyzes and processes the fetal electrocardio-complex waves to obtain a group of characteristic waveforms of each fetal electrocardio-complex wave or calculates a fetal cardiac axis vector of a front coordinate relative to the parent directly according to the fetal electrocardio-complex waves.

Description

technical field [0001] The present invention relates to a maternal fetal monitoring device and method, in particular to a monitoring device for fetal movement, uterine contraction and fetal position. Background technique [0002] The mother, also known as a pregnant woman, is most concerned about the health and normal development of the child in her womb, as well as premature birth. In addition to outpatient physicians who can assist in the examination, you can only rely on your own observation at home, such as evaluating the condition of the fetus by feeling the number of fetal movements. If you want to observe and record for a long time, it is really inconvenient, so it is best to have a set of equipment that can be carried around, can automatically detect and record, and can know the fetal position / fetal movement, health and development status of the fetus through data analysis and display . In this way, the information of these home measurement records can be presented...
