Noninvasive Detection of Cerebral Blood Flow and Blood Oxygen Based on Inductive Sensing Technology and Near Infrared Spectroscopy

The synchronous monitoring of cerebral blood flow and blood oxygen levels plays a pivotal role in the prevention, diagnosis, and treatment of cerebrovascular diseases. This study introduces a novel noninvasive device utilizing inductive sensing and near-infrared spectroscopy technology to facilitate simultaneous monitoring of cerebral blood flow and blood oxygen levels. The device consists of modules for cerebral blood flow monitoring, cerebral blood oxygen monitoring, control, communication, and a host machine. Through experiments conducted on healthy subjects, it was confirmed that the device can effectively achieve synchronous monitoring and recording of cerebral blood flow and blood oxygen signals. The results demonstrate the device’s capability to accurately measure these signals simultaneously. This technology enables dynamic monitoring of cerebral blood flow and blood oxygen signals with potential clinical applications in preventing, diagnosing, treating cerebrovascular diseases while reducing their associated harm.
