Wireless fetal rhythm monitoring device and method

Abstract

The invention relates to a wireless fetal heart monitoring device, which comprises an ultrasonic sending module, an ultrasonic transducer, an ultrasonic demodulation module and a wireless communication module, wherein, the ultrasonic transducer is driven by the ultrasonic sending module to generate ultrasonic waves, and an ultrasonic echo wave signal can be received by the ultrasonic transducer and the scoustoelectric transformation of the ultrasonic echo wave signal is performed, the processed ultrasonic echo wave signal is input into the ultrasonic demodulation module and the demodulation process is performed, the fetal heart beat signal is extracted and then transmitted to a wireless receiving device of the fetal monitoring computer by the wireless communication module. Because the structure combines the wireless communication technology with the Doppler ultrasonic wave drive as well as the demodulation technology ingeniously, the fetal heart beat signal collecting device and the monitoring computer are separated, and a gravida is not constrained by the monitoring computer anymore, thereby making the movement to be free and convenient.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fetal monitoring device and method. Background technique [0002] Fetal surveillance is a method to evaluate the development and safety status of the fetus in utero by means of biophysics and biochemistry. Fetal monitoring is an important means to ensure the safety of mothers and fetuses and to achieve prenatal and postnatal care. Traditional fetal monitoring refers to electronic fetal heart rate monitoring (Electronic FetalHeartRate Monitoring, EFM) and fetal heart contraction monitoring (cardiotocography, CTG). With the society's increasing requirements for the health and safety of mothers and infants, the study of the physiology and pathology of fetal development has become an important topic. In particular, fetal heart rate has a broad application prospect and significance of in-depth research in clinic. [0003] Because pregnant women need an instrument that can provide...

AI Technical Summary

Problems solved by technology

Especially during the delivery process, the movement and body position changes of the parturient will pull the lead wire of the monitoring device, resulting in poor contact between the probe and the parturient or position deviation, resulting in errors in monitoring parameters

Simultaneously, all kinds of wires are entangled on the body of the puerpera, which brings great inconvenience and discomfort, and even affects the physiological and psychological conditions of the puerpera in severe cases.

These disadvantages are especially evident during long-term monitoring and water birth
