Abstract

The invention discloses a fetal heart audio signal processing device and fetal monitoring equipment. The fetal heart audio signal processing device comprises a fetal heart audio signal detection front end, a frequency shift input end, a frequency shift processing module and a frequency shift output end, wherein the fetal heart audio signal detection front end is used for generating ultrasonic beams and acquiring fetal heart audio signals based on the ultrasonic beams; the frequency shift input end is coupled with the output end of the fetal heart audio signal detection front end; the frequency shift processing module is coupled with the frequency shift input end; the frequency shift output end is coupled with the frequency shift processing module; the frequency shift processing module is used for carrying out frequency shift processing on the fetal heart audio signals, input via the frequency shift input end, of the fetal heart audio signal detection front end; the fetal heart audio signals subjected to frequency shift processing are output via the frequency shift output end. The device and the equipment, which are provided by the invention, can achieve the effects of improving the playing effects of the fetal heart audio signals in audio playing equipment and improving the possibility of extensive use of fetal monitoring.

Description

technical field [0001] The invention relates to the field of fetal heart electronic monitoring, in particular to a fetal heart audio signal processing device and fetal monitoring equipment. Background technique [0002] Ultrasonic Doppler fetal monitor (hereinafter referred to as fetal monitoring) and ultrasonic Doppler fetal heart rate meter (hereinafter referred to as fetal heart rate Doppler) and other fetal monitoring equipment are widely used in hospitals or social health and other medical units, and gradually penetrate into the In home applications, fetal monitoring plays a very important role in improving maternal and fetal health. [0003] The current international fetal monitoring method is to detect the fetal heart rate (FHR, Fetal Heart Rate), and the detection of the fetal heart rate needs to be performed under the hearing of a reliable fetal heart audio signal (hereinafter referred to as fetal heart sound). In the field of electronic fetal heart monitoring, the...
