Problems solved by technology
[0003] The existing fetal heart detection equipment needs the ultrasonic beam to be aimed at the fetus, and a part of the incident ultrasonic beam is radiated to the fetal heart movement surface. Due to the uncertainty of the fetal position and the fetal heart position, it is sometimes difficult for professional medical staff to find the fetal heart location, making it more difficult for ordinary personnel to monitor and record fetal heart rate by performing real-time fetal heart rate detection
Since the existing fetal heart rate detection equipment has high requirements on the user's technical level, fetal he

Embodiment Construction
[0037] The present invention will be described in detail below in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.
[0038] Such as figure 1 As shown, the fetal heart rate detection device provided by the present invention includes a sensor 1 , a low-pass filter 2 , an A / D converter 3 , a signal processor 4 , a display and / or early warning module 5 , a power supply module 6 and a carrying device 7 .
[0039] The present invention contacts the sensor 1 with the mother's finger, earlobe or wrist through the bearing device 7 to obtain the mother's pulse signal. The present invention considers that the fetus is in the mother's body, and its fetal heart pulsation will inevitably cause the mother's blood vessels to have the same regularity. Pulsation information, so the pulse signal obtained...

The invention relates to a fetal-heart detection device. The fetal-heart detection device is characterized by comprising a signal obtaining device for obtaining synthesizing pulse signals from a parent body, a signal processor for separating the synthesizing pulse signals to obtain fetal heart rate data, a display and/or early warning device for displaying and/or early warning the obtained fetal heart rate data and a power supply module for supplying power to all devices of the fetal-heart detection device, wherein the synthesizing pulse signals comprise parent body pulse signals and fetal pulse signals. The fetal-heart detection device can be widely applied to fetal heart detection.
Description
technical field [0001] The invention relates to a fetal heart detection device capable of detecting fetal heart rate from a maternal pulse signal, and relates to the technical field of medical equipment. Background technique [0002] Fetal heart detection equipment is a very common medical and household equipment. At present, most of the fetal heart detection equipment is based on the principle of non-focused ultrasound Doppler. Record fetal heart rate function. During detection, the ultrasonic beam generated by the ultrasonic transducer is directly aimed at the fetus, and a part of the incident ultrasonic beam hits the surface of the fetal heart movement. Due to the Doppler effect, the frequency of the ultrasonic wave is shifted and detected by the receiving transducer. The low-frequency signal related to the fetal heart rate is separated to complete the detection of the fetal heart rate. [0003] The existing fetal heart detection equipment needs the ultrasonic beam to b...
