Embodiment 1

[0031] Example 1: A pregnant woman is 20 weeks pregnant. The ultrasonic transducer collects the fetal heart sound signal, and the heartbeat rhythm is 148 beats / min. The interface module transmits the fetal heart sound signal to the extended application terminal through the audio cable. An example of the extended application terminal is APP. The APP processes the fetal heart sound signal and converts it into a digital signal for display, and at the same time transmits the fetal heart sound signal to the sound amplification signal circuit By zooming in, the user can observe the fetal heart rate data through the APP and hear the fetal heart sound at the same time.

Embodiment 2

[0032] Example 2: A pregnant woman is 20 weeks pregnant, and the ultrasonic transducer collects fetal heart sound signals, and the detected instantaneous fetal heart rate exceeds 160 beats / min several times (the range of normal fetal heart rate is 120 beats / min-160 beats / min. points), when the fetal heart rate is found to exceed the normal range during the processing of the extended application terminal, an alarm signal will be added to the fetal heart sound signal, input to the fetal heart rate instrument, and the speaker will play the fetal heart sound signal and reminder signal at the same time, prompting Attention pregnant women.

Embodiment 3

[0033] Example 3: A pregnant woman collects the sound of the fetus in the abdomen through the fetal heart rate device during pregnancy, such as the pregnant woman's own heartbeat, and stores it in the extended application terminal after output. Within one month after the baby is born, the stored The sound is input into the fetal heart rate instrument to play, so as to create a familiar environment for the newborn baby and realize the soothing function.

[0034] The integrated Doppler fetal heart rate meter that can be extended and applied in the present invention can combine the functions of the traditional integral type fetal heart rate meter and the split type fetal heart rate meter, not only can detect fetal heart sounds, but also can be connected to an extended application terminal to collect It is easy to use and low cost to organize and analyze the relevant data.

[0035] Using the audio interface to obtain fetal heart sound information has the following advantages: the ...

Abstract

The invention discloses an integrated Doppler fetal heart instrument capable of extended application, which comprises an earphone interface module, and an ultrasonic transducer, a sound amplifying signal circuit, a high-low channel filter circuit, an analog switch and an audio amplifying module connected in sequence, wherein one end of the earphone interface module is connected with the analog switch, and the other end is connected with an extended application terminal; fetal heart sound signals acquired by the ultrasonic transducer sequentially pass through the sound amplifying signal circuit, the high-low channel filter circuit, the analog switch and the audio amplifying module, and the audio amplifying module plays the fetal heart sound signals; the earphone interface module detects signals of the extended application terminal and controls the analog switch, the amplified sound signals are sent to the extended application terminal, and the extended application terminal processes the sound data. According to the fetal heart instrument, fetal heart sound can be detected, the fetal heart instrument can be connected with the extended application terminal for sorting and analyzing acquired data, the use is convenient, and the cost is low.

Description

technical field [0001] The invention relates to an integrated doppler fetal heart rate instrument which can be extended and applied, which is used for monitoring the fetal heart rate and belongs to the technical field of medical devices. Background technique [0002] The fetal heart rate monitor is a medical instrument, which is used to detect the fetal heartbeat and amplify the weak fetal sound signal of the fetus so that people can easily hear it. According to professional medical knowledge, the fetal heart rate or instantaneous heart rate curve can be used to judge whether the fetus is normal. . [0003] Technically speaking, the Doppler fetal heart rate monitor is divided into two types: integrated type and split type. The integrated type fetal heart rate monitor amplifies the weak fetal heart sound signal of the fetus. module. [0004] At present, the popular home fetal heart monitors on the market are mostly integrated structures, which are convenient to use, but can...
