Embodiment 1

[0069] A portable fetal movement monitor, such as Figure 1 to Figure 5 As shown, it includes a smart bracelet worn on the pregnant woman's wrist, a fetal movement sensing patch attached to the pregnant woman's belly, and a fetal heart rate sensing patch attached to the pregnant woman's belly. The smart bracelet includes a pair of wrist straps 1, one of which is A plurality of sockets 11 are provided on the outer surface of the band 1, and a connection frame 12 is installed at one end of the other wrist strap 1, and a pin 13 is arranged at the center of the connection frame 12, and a display screen 14 is installed between the two wrist straps 1, and the fetal movement The induction patch includes a first patch 2, a fetal movement sensing module 21 is installed at the center of the first patch 2, connecting strips 22 are respectively arranged around the outer wall of the first patch 2, and an adhesive strip 23 is arranged at one end of the connecting strip 22 The fetal heart se...

Embodiment 2

[0078] As the second embodiment of the present invention, in order to facilitate the monitoring of fetal movement signals, the inventors collect the fetal heart signal by setting a speed sensor chip. As a preferred embodiment, as Figure 7 As shown, the speed sensor chip also includes a fetal movement signal preprocessing module, a fetal movement signal feature extraction module, a fetal movement signal identification module and a fetal movement data storage module, the fetal movement signal preprocessing module is used to preprocess the monitored fetal movement signal, and the fetal movement signal feature extraction The module is used for feature extraction of the preprocessed fetal movement signal, the fetal movement signal identification module is used for identifying the fetal movement signal, and the fetal movement data storage module is used for storing the fetal movement data.

[0079] In this embodiment, the speed sensor chip is designed based on the model MMA8451 acce...

Embodiment 3

[0083] As a third embodiment of the present invention, in order to facilitate the accurate extraction of fetal movement signal features, the inventors made improvements to the fetal movement signal feature extraction module, as a preferred embodiment, such as Figure 10 As shown, the fetal movement signal feature extraction module includes a standard deviation analysis module, an energy characteristic response module, a kurtosis response module and a time-frequency region analysis module. The standard deviation analysis module is used to analyze the standard deviation of the fetal movement data, and the energy characteristic response module is used for For analyzing the energy characteristic response of the fetal movement data, the kurtosis response module is used for analyzing the kurtosis response of the fetal movement data, and the time-frequency region analysis module is used for analyzing the time-frequency region of the fetal movement data.

[0084] In this embodiment, th...

Abstract

The invention relates to the technical field of fetal movement monitoring, in particular to a portable fetal movement monitor comprising a smart bracelet worn on the wrist of a pregnant woman, a fetalmovement sensing patch attached to the belly of the pregnant woman and a fetal heart sensing patch attached to the belly of the pregnant woman. The portable fetal movement monitor is attached to thebelly of the pregnant woman through a set magnetic sensor chip, can position the fetus in the pregnant woman conveniently, and monitors the activity of the fetus to obtain fetal movement data. Fetal heart signals are monitored through a set vibration sensor chip, and the monitored fetal heart signals are counted through a fetal movement counting module to obtain the fetal heart data. The smart bracelet is used as a collection terminal, and the acquired fetal movement data and fetal heart data are digitally displayed through the smart bracelet for the pregnant women to observe. At the same time, the overall monitor is small in structure, complete in function, convenient to carry and suitable for home use.

Description

technical field [0001] The invention relates to the technical field of fetal movement monitoring, specifically a portable fetal movement monitoring instrument. Background technique [0002] Fetal heart rate and fetal movement is a routine method to check whether the fetal development is normal. Fetal movement is the first objective sign of fetal life, which can be detected at six to eight weeks of gestation, but it is generally not until four and a half months of pregnancy that the pregnant woman can feel fetal movement for the first time. [0003] In clinical practice, the fetal heart rate monitor that integrates fetal heart rate, fetal movement, and uterine contractions used in hospitals has a large overall structure and is not easy to carry. It is difficult to accurately obtain the fetal heart rate and fetal movement data by relying on silent counting. In view of this, we propose a portable fetal movement monitor. Contents of the invention [0004] The purpose of the...
