Monitoring method capable of replaying fetal-heart Doppler audio signals

Abstract

The invention relates to the technical field of medical monitoring, and specifically relates to a monitoring method and device capable of replaying fetal-heart Doppler audio signals. The method disclosed by the invention comprises the following steps of: acquiring and storing fetal-heart monitoring signals; comparing the acquired fetal-heart monitoring signals with a judgment standard, and if the comparison result is abnormal, adding an abnormal mark in the result; when a user needs to replay the fetal-heart monitoring signals, replaying the fetal-heart monitoring signals; and carrying out judgment on the abnormal state of the fetal-heart monitoring signals by the user according to the replayed fetal-heart monitoring signals, and carrying out redefinition on the mark according to the judgment result. According to the technical scheme provided by the invention, even if doctors are not beside a fetal monitor, the doctors also can replay an audio through an audio recording module to hear fetal heart sound in follow-up time in case that the fetal heart of a fetus is subjected to a complicated heartbeat situation, and then judges whether heart rate miscalculation or real fetal-heart mutation occurs according to the beat of the audio, so that the possibility of misjudgment on fetal-heart beats is greatly reduced, and the diagnosis of the doctors is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical monitoring, in particular to a monitoring method capable of playing back fetal heart rate Doppler audio signals. Background technique [0002] Ultrasonic Doppler fetal monitor, which is widely used in obstetrics and clinics, utilizes a characteristic of sound - the Doppler principle, which means that the echo reflected by a moving object will have a frequency offset when the sound encounters a moving object, and the offset is related to the moving object proportional to the speed. The ultrasound probe of the fetal monitor is placed in the abdomen of the pregnant woman, emits ultrasound toward the fetal heart, and receives the echo. Since the heart wall and valve velocity corresponding to the fetal heartbeat are within a certain range, the monitor can identify the fetal heartbeat after amplification and filtering. The reflected echo, the fetal monitor also uses this echo cycle to calculate the fet...

Problems solved by technology

If the doctors and nurses are busy at this time and are not next to the fetal monitor and do not hear the fetal heart rate Doppler audio, it is difficult to judge whether it is a real fetal heart rate deceleration or a mistake caused by a principle defect only based on the fetal heart rate curve. Forget it, it brings doubts to the doctor's diagnosis
