Benefits of technology

This patented technology monitors changes made during pregnancy through an active method that involves measuring electrical signals from the mother's uterine artery (the blood vessel) or other parts inside her underwear such as muscle tissue near its opening. By doing this, these measurements help healthcare professionals identify any abnormalities early enough before they are able to take appropriate actions like giving birth counselings or taking medication safely.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving upon conventional techniques used for measuring fetal cardiac rates (FHR) such as ultrasound Doppler flowmetry, while also allowing them to provide real-world data from their surroundsings without being affected by external factors like weather conditions or interference between different devices.

Abstract

The invention discloses a fetal heart rate monitoring belly supporting belt based on optical fiber sensing. The fetal heart rate monitoring belly supporting belt is characterized in that each pre-bent optical fiber sensing unit is fixed on a corresponding vibration sensitive membrane, and each pre-bent optical fiber sensing unit and the corresponding vibration sensitive membrane are embedded in a fabric of a belly supporting belt body; a light source is used for sending laser to each pre-bent optical fiber sensing unit, and an optical signal receiving assembly is used for receiving laser signals modulated by vibration signals when passing through each pre-bent optical fiber sensing unit and converting the laser signals modulated by the vibration signals into corresponding multi-path electric signals with physiological feature information; and a signal processing and analyzing module is used for separating fetal heartbeat information. The vibration signals caused by heartbeat and fetal movement of a fetus are sensed based on an optical fiber high-sensitivity vibration sensing technology, and continuous real-time monitoring of the health state of the fetus is achieved through processing and analysis of the multi-path signals.
