Problems solved by technology

The existing fetal heart rate and fetal movement monitors are generally considered for singleton pregnant women, but for twins and multiple births, it is inconvenient to use, and the obtained fetal heart rate data is not accurate enough
And after giving birth, pregnant women no longer need fetal heart rate and fetal movement monitors, resulting in a waste of resources
In addition, there is no convenient way to transmit the collected fetal heart rate and fetal movement to the doctor so that they can judge the health status of the fetus

Embodiment Construction

[0019] The present invention is composed of a signal processing module, an audio output module, a display module, a communication module, a control module and a main control module;

[0020] Signal processing module: use Butterworth 2nd-order low-pass filter, chip U1 is OP07 operational amplifier integrated circuit, filter and amplify the input signal.

[0021] The signal is input from Vin, connected in series with resistor R1, resistor R3, capacitor C2, and capacitor C4, and then connected to the input from pin 3 of chip U2 and output from pin 6. R3 is connected in parallel with capacitor C1 to the output terminal, and R2 is connected in parallel to ground. C4 connects R4 in parallel to the output terminal, and connects C3 in parallel to ground. Pin 3 in parallel with R5. The output terminal is connected to U2 pin 2 after connecting R7 in parallel, and grounding after connecting R6 and R7. Pin 7 of U2 is connected to +5V voltage, and pin 4 is connected to -5V voltage.

Abstract

The invention discloses a multi-fetus heartbeat and movement monitor based on a wireless protocol, belongs to the technical field of electronics, and aims at providing the heartbeat and movement monitor which is not only oriented to single-fetus pregnant women, can also be more conveniently used for dual-fetus or multi-fetus pregnant women, and is provided with a replaceable ultrasonic probe and based on the wireless protocol.The multi-fetus heartbeat and movement monitor is composed of a signal processing module, an audio output module, a display module, a communication module, a control module and a main control module.Fetal heartbeat and movement monitoring service based on the wireless protocol can be more conveniently and accurately provided for dual-fetus or multi-fetus pregnant women.Heartbeat and movement information of two or more fetuses can be obtained from multiple signals at the same time, the multi-fetus heartbeat and movement monitor can be conveniently used for dual-fetus or multi-fetus pregnant women, and meanwhile single-fetus pregnant women can obtain more accurate data.

Description

technical field [0001] The invention belongs to the field of electronic technology. Background technique [0002] At present, the fetal heart rate and fetal movement monitor has been widely used in the field of clinical and home monitoring. It is used by pregnant women to monitor the heart rate of the fetus in the pregnant woman's abdomen anytime and anywhere, and enables doctors to know the status of pregnant women at any time, which is convenient for doctors and patients. communicate. Existing fetal heart rate and fetal movement monitors are generally considered for singleton pregnant women, while twin and multiple pregnancy pregnant women have inconvenience in use, and the fetal heart rate data obtained are not accurate enough. And after giving birth, the pregnant woman no longer needs the fetal heart rate and fetal movement monitor, resulting in a waste of resources. In addition, there is no convenient way to transmit the collected fetal heart rate and fetal movement t...
