Embodiment 1

[0023] A method for synchronous playback of Doppler fetal heart rate audio signal and fetal heart rate, the method specifically includes the following steps:

[0024] a, the fetal heart audio signal is collected by the audio signal acquisition device, and the fetal heart audio signal is stored as a digital audio signal;

[0025] b. Restore the digital audio signal stored in a to an analog signal, in preparation for playback and recalculation of the fetal heart rate;

[0026] c. Connect the analog signal restored by b to the calculation circuit to recalculate the fetal heart rate;

[0027] d. Synchronously output the playback of the analog audio signal of b and the calculation result of the fetal heart rate of c.

Embodiment 2

[0029] A method for synchronous playback of Doppler fetal heart rate audio signal and fetal heart rate, the method specifically includes the following steps:

[0030] a. The fetal heart audio signal is collected by the audio signal acquisition device, and the fetal heart audio signal is stored as a digital audio signal to prepare for the playback of the audio signal;

[0031] b. Perform real-time calculation on the fetal heart rate audio signal collected in a, and store the real-time calculation result;

[0032] c. While playing back the audio signal of a, call out the real-time calculation result, and output the audio signal playback and real-time calculation result synchronously.

Embodiment 3

[0034] A method for synchronous playback of Doppler fetal heart rate audio signal and fetal heart rate, the method specifically includes the following steps:

[0035] a. The fetal heart rate audio signal is collected by the audio signal acquisition device, and the fetal heart rate audio signal is stored as a digital audio signal to prepare for audio signal playback and fetal heart rate recalculation;

[0036] b. Using a digital signal processing method to directly calculate the digital audio signal stored in a;

Abstract

A method for synchronously reproducing the Doppler audio signal and rhythm of fetal heart includes such steps as acquiring and storing the Doppler audio signal of fetal heart, calculating the relative rhythm of fetal heart, and synchronously reproducing them. Its device is also disclosed.

Description

technical field [0001] The invention relates to a method and device for detecting and monitoring Doppler fetal heart rate, in particular to a method and device for synchronous playback of Doppler fetal heart rate audio signal and fetal heart rate. Background technique [0002] The Doppler fetal heart rate audio signal detected by the ultrasonic Doppler fetal heart rate monitor or the ultrasonic Doppler fetal heart rate stethoscope can be stored by the recording device for later playback. Similar devices in the prior art either only have digital display of fetal heart rate or audio frequency of fetal heart rate during playback, and cannot provide complete digital display of fetal heart rate and audio detection and monitoring record information of fetal heart rate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a Doppler fetal heart rate audio signal that can not only playback the fetal hea...
