A research group led by Associate Professor Guangho Son of the Graduate School of Information Science and Engineering, The University of Electro-Communications, and Yoshihide Abe, Director of the Children's Center at Koto Toyosu Hospital, Showa University, used a medical radar to monitor vital signs such as pulse and respiration in neonatal intensive care units. We have developed a signature detection system.Advanced signal processing enables non-contact measurement.
According to the University of Electro-Communications, the system includes a 24 gigahertz non-contact medical radar, a non-linear filter that separates breathing and heartbeat signals, an algorithm to extract heartbeat signals, and an algorithm to estimate pulsations in time series. A clinical trial was conducted on 24 healthy adult men and women around the age of 9, and 2 young children, including 3 newborns, and it was confirmed that the sensor could measure with accuracy approaching that of conventional contact sensors.
Children have immature physiological functions, and it is said that their vital signs tend to fluctuate due to external stimuli.However, since they cannot complain of pain or symptoms on their own, it is important to quickly detect changes in vital signs and detect abnormalities.
By using this system, it is possible to check the health status of children in various places, such as at home and in the car. Expectations for high-precision detection technology are also increasing.The research group believes that the application of this technology can be expected to help manage health in medical and home care, as well as resolve labor shortages in medical and welfare settings.
