Problems solved by technology

[0004] The fetal monitor with wireless probe can free the mother from the shackles of cables and realize free monitoring, but there are still the following problems in use: the current wireless fetal heart rate monitoring probe can only collect fetal heart sound signals, and can only record fetal heart sound signals in real time. can be transmitted to the host computer, the host computer can accurately calculate the fetal heart rate
In addition, because the wireless probe integrates more circuits and is thicker, it needs to be fixed with a strap when using it. As a result, the probe is prone to rollover when the pregnant woman is standing or walking for monitoring, resulting in the loss of monitoring data.

Embodiment 1

[0034] refer to Figure 1~2 , the present embodiment provides a wearable fetal monitor, which is characterized in that it includes a shell 1 (101) and a shell 2 (102) connected to each other; the shell 2 (102) can be connected by a strap (103) fixed on the abdomen of the pregnant woman, the housing 1 (101) can be worn on the strap (103);

[0035] The housing 1 (101) is provided with an ultrasonic transceiving module (201), an ultrasonic demodulation module (202) and a fetal heart processing module (203) connected in sequence, and an ultrasonic converter is provided in the housing 2 (102). energy device (204);

[0036] The ultrasonic transceiver module (201) is used to drive the ultrasonic transducer (204) to send ultrasonic waves, and receive echo signals and transmit them to the ultrasonic demodulation module (202), and the ultrasonic demodulation module (202) decodes After the fetal heart sound signal is extracted, the fetal heart rate is analyzed and calculated by the fet...

Embodiment 2

[0041] refer to Figure 3-4 , as a further improvement of the present invention, the improvement between Embodiment 2 and Embodiment 1 is that the wearable fetal monitor further includes a housing 3 (301) connected to the housing 1 (101), the The housing 3 (301) is provided with a pressure sensor (401); in order to analyze the pressure value monitored by the pressure sensor, the housing 1 (101) is also provided with a uterine pressure signal processing module (402) for analyzing Calculate the contraction pressure value.

[0042] When in use, the housing 2 (102) and the housing 3 (301) are fixed on the abdomen of the pregnant woman through a strap (103) for monitoring fetal heart signals and uterine pressure signals, and the housing 1 (101) Can be worn on the strap (103).

[0043] Further, the housing 1 also includes a fetal movement recording module for recording fetal movement. The fetal monitoring device also includes a housing 4 connected to the housing 1 , and a recordi...

Embodiment 3

[0046] As a further improvement of the present invention, the improvement between Embodiment 3 and Embodiments 1 and 2 lies in that a storage module is further provided in the housing 1, and the storage module is used to store the monitored parameter signals in real time.

[0047] Furthermore, a wireless communication module is also provided in the housing 1, and the wireless communication module is used for wireless connection with external devices, and the external devices include mobile smart terminals, PCs, and other fetal monitors.

[0048] Due to the inherent characteristics of the wearable fetal monitor, issues such as size and weight need to be considered during design. Therefore, after obtaining the fetal heart rate, it needs to be transmitted to another device for subsequent processing and analysis of the fetal heart rate curve. Other devices Including mobile smart terminals, PCs, other fetal monitors, etc. The advantage of adding a storage module and a wireless comm...

Abstract

The invention discloses a wearable fetal monitor, which is characterized in that it includes a shell 1, a shell 2, and a shell 3 connected to each other; the shell 2, and the shell 3 can be fixed on the abdomen of a pregnant woman through a strap Position, the housing 1 can be worn on the strap; the housing 1 is equipped with an ultrasonic transceiver module, an ultrasonic demodulation module, a fetal heart signal processing module, and a uterine pressure processing module. The housing 2 An ultrasonic transducer is arranged inside, and a pressure sensor is arranged inside the housing 3 . The casing 1 is also provided with safety protection modules such as a temperature monitoring module, a timing module, and a self-checking module. In the wearable fetal monitor provided by the present invention, the main unit (housing 1) of the fetal monitor can be worn on the puerpera or held in the hand, and the pregnant woman can perform fetal monitoring when standing or walking, and the fetal monitoring is more free; and the main unit There are also uterine pressure monitoring and safety protection modules inside, which are safer and more reliable.

Description

technical field [0001] The invention relates to the field of medical monitoring, in particular to a wearable fetal monitor. Background technique [0002] At present, the most widely used electronic fetal heart monitoring method in clinical practice is fetal heart contraction monitoring (Cardiocotography, CTG). When monitoring fetal heart rate and uterine contraction, it is necessary to record the fetal heart rate uterine chart in real time, including the fetal heart rate curve (fetal heart rate, FHR) and the uterine contraction curve (tocography, TOCO) of the mother's uterine pressure. Then, the doctor analyzes the fetal heart rate and uterine contraction curve according to certain standards, and then evaluates the health status of the fetus. [0003] Existing fetal monitors can be divided into two categories: wired probe monitoring and wireless probe monitoring. These two types of monitors include the host part. The difference lies in the way the probe collects fetal heart...
