Biological tissue blood flow real-time monitoring system and simulation monitoring system based on magnetic induction phase displacement

Abstract

The invention discloses a biological tissue blood flow real-time monitoring system and simulation monitoring system based on magnetic induction phase displacement. The system comprises a signal source, an exciting coil unit, a receiving coil unit, a digitizer and a host computer PC. The signal source outputs two sinusoidal signals with the same frequency and phase and is respectively connected with the exciting coil unit and the digitizer, and the receiving coil unit is connected with the digitizer and is used for collecting an output signal which is sent by the exciting coil unit and is generated in the receiving coil unit after passing through a to-be-detected part; and the real-time state of the to-be-detected part is obtained by transmitting the output signals to the host computer for analysis and processing. The system provided by the invention utilizes the magnetic induction phase shift to monitor the cerebral blood flow pulsation condition, continuously and effectively monitors the change of the cerebral blood flow pulsation through the combination of the arterial blood flow dynamics theory and the magnetic induction phase shift detection principle, and has the advantages of being noninvasive, safe, non-contact, small in size and high in penetrability.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a biological tissue blood flow real-time monitoring system and an analog monitoring system based on magnetic induction phase shift. Background technique [0002] Stroke has become a global public health threat. In recent years, the incidence of hemorrhagic stroke has gradually decreased, but the incidence of ischemic stroke has exploded. In 2018, the American Heart Association / American Stroke Association pointed out that maintaining a normal level of blood supply to the brain is the key to treating ischemic stroke. Therefore, real-time monitoring of cerebral blood flow has important clinical significance. [0003] There is currently no safe, fully acceptable method for real-time continuous monitoring of cerebral blood flow. Imaging methods such as CT and MRI are commonly used clinically to detect blood flow and infarction. However, traditional imaging equipment is bulky an...
