Method, device and system for processing fetal heart sound data

Abstract

The invention discloses a method, device and system for processing fetal heart sound data. The method includes: converting the received ultrasonic echo signal into an electrical signal; preprocessing the electrical signal to obtain a fetal heart sound signal; performing AD sampling on the fetal heart sound signal according to a preset sampling frequency, and converting the AD sampled The data is numbered and cached in the cache module; the data to be sent is read from the cache module according to the preset reading frequency and the first preset rule, and the data to be sent is combined into the data to be sent according to the second preset rule UDP data packet; send the UDP data packet to the wireless player, wherein the wireless player will analyze the received UDP data packet, and arrange the data in the parsed UDP data packet according to the number, and arrange the The data is DA converted to generate an analog signal and played back. Thereby, the real-time performance and continuity of fetal heart sound playback can be guaranteed, and the delay of fetal heart sound playback can be reduced.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method, device and system for processing fetal heart sound data. Background technique [0002] Fetal heart rate is related to the whole pregnancy process of pregnant women. Fetal heart rate is an important parameter for pregnant women or medical staff to judge the health of the fetus in the abdomen. Fetal heart rate is an important means to predict the safety of the fetus. Pregnant women who are over 28 weeks have to go to the hospital for a check-up. During the monitoring process of about 30 minutes, the doctor judges whether the fetus is normal according to the fetal heart rate curve printed by the monitor. Before doing fetal monitoring, medical staff need to bind a sensor probe to the pregnant woman's belly. The sensor probe converts the collected ultrasonic signal into an electrical signal, and the real fetal heart rate data is calculated by the probe itself or transmitted to...

AI Technical Summary

Problems solved by technology

Before doing fetal monitoring, medical staff need to bind a sensor probe to the pregnant woman's belly. The sensor probe converts the collected ultrasonic signal into an electrical signal, and the real fetal heart rate data is calculated by the probe itself or transmitted to the monitor. The above display, so the signal collected by the probe is very important for a fetal monitoring. When the position of the probe is not facing the fetal heart, no clear signal can be collected, which will cause the probe or monitor to calculate inaccurate fetal data. heart, it will affect the doctor's diagnosis or even misdiagnosis, which may cause medical accidents and tragedies

[0003] However, the existing method of determining the fetal heart rate by listening to the fetal heart sound at the wireless playback end through wireless audio transmission has the following defects: First, due to the instability of wireless transmission and the interference of other radio frequency signals, the sound leakage phenomenon is very serious. Serious; Secondly, the fetal heart sound delay of this playback mechanism is more serious

These problems will lead to the inability to find the exact fetal heart rate, which in turn will lead to inaccurate calculation of fetal heart rate and misdiagnosis by doctors.
