Embodiment Construction

[0054] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0055] Below at first the principle of the present invention is described:

[0056] The low-frequency and weak characteristics of human bioelectric signals determine that they are easily interfered by other signals of the human body, and its instability and randomness also bring many difficulties to its detection and extraction. Fetal ECG signals are a typical example. For example, the fetal ECG signal detected from the human body surface is not only interfered by the maternal ECG signal and myoelectric signal in the human body, ...

Abstract

The invention provides a fetal electrocardiogram signal detecting system. A first electrode set is arranged on a maternal shoulder part; a second electrode set is arranged on a maternal belly part, and is used for collecting a maternal belly signal; a signal acquisition module is used for acquiring the maternal belly signal and sending the maternal belly signal to an AD (Analog to Digital) conversion module; the AD conversion module is used for carrying out AD conversion on the maternal belly signal and generating the maternal belly signal in a digital signal manner; a control module is used for preprocessing and filtering the maternal belly signal and sending the maternal belly signal to a communication module; the communication module is used for forwarding the maternal belly signal to an upper computer; and the upper computer adopts a flank bipolar montage system for analyzing the maternal belly signal, and utilizes a component analysis method for separating a preliminary fetal electrocardiogram signal from the maternal belly signal. According to the fetal electrocardiogram signal detecting system provided by the invention, the weak fetal electrocardiogram signal can be extracted from a body surface, and the diagnosis of corresponding diseases is made according to relevant parameters of a fetal electrocardiogram.

Description

technical field [0001] The invention relates to the technical field of electrocardiogram monitoring, in particular to a fetal electrocardiogram signal detection system. Background technique [0002] According to statistics, the infant mortality rate in 2004 was 10.63% 0 "1; and a large part of my country's mentally handicapped children were caused by the distressed state of hypoxia and ischemia during the birth of the fetus. According to clinical experience, if the fetus can be treated With timely and effective monitoring, some maternal deaths and disabled babies can be avoided, and 25% of perinatal deaths can be avoided. Maternal and infant mortality is the core indicator for the international community to evaluate the level of maternal and child health care in a country and region. Good pregnancy Monitoring is a reliable guarantee for maternal and fetal safety. In recent years, with the development of perinatal medicine, the requirements for the content and accuracy of fetal...
