Researchers at the Pater Institute of Engineering and Technology in Manoharbhai, India, have developed a new family fetal heart rate monitor with a dual-microphone system that monitors fetal heart rate while feeding back information to the wave analyzer. The analyzer and bed Connected to a personal computer. This monitor can be used to protect the fetus in complex environments.
In the two microphones, the first microphone is connected to the belly of the pregnant woman to detect the fetal heartbeat, and the second microphone collects the surrounding noise at a certain distance. The analysis software subtracts the "noise" from the fetal sound to generate a waveform (WAV) file to further analyze the medical abnormality. If an abnormality is found, the WAV file can be compressed into the MP3 file format and quickly uploaded to the doctor's computer network, and a warning is sought. Medical assistance. An article describing the functionality of this monitor was published in the August 2009 issue of the International Journal of Engineering Systems Modeling and Simulation.
The main author of the article, AK Mittra, assistant professor of the Department of Electronic Engineering, said that "the monitor can provide convenient monitoring at home at any time. After an abnormality, emergency medical assistance can be called to effectively prevent stillbirth and other prenatal syndrome. The results show that the method is suitable for long-term effective fetal heart rate monitoring."
