Abstract

A cerebrovascular regulation function monitor system and a method for detection of cerebrovascular circulation critical closing pressure, wherein the cerebrovascular regulation function monitor system includes a signal collection system for in-phase sampling analog signal of transcranial doppler (TCD) signal and continuous artery pressure signal and further converting the analog signals into correspondent digital signals and a signal processing / displaying system connected with the signal collection system via interfaces for processing the digital signals to obtain the cerebrovascular critical closing signal and displaying them. The method and system realize a non-invasion detection and monitor of cerebrovascular autoregulation function in clinical practice.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a non-invasive cerebral blood flow automatic regulation function detection / monitoring system and a method for real-time detection of the critical closing pressure of cerebral circulation, thereby realizing clinical non-invasive detection and monitoring of the lower limit of cerebral blood flow automatic regulation. Background technique

[0002] The autoregulation function of human cerebral blood flow is very important in the occurrence, development, diagnosis and treatment of cerebrovascular diseases. Therefore, accurate and practical non-invasive cerebral blood flow autoregulation function detection / monitoring equipment is urgently needed clinically. Traditional physiological theory holds that cerebral blood flow depends on the pressure difference between mean arterial pressure and intracranial pressure (or venous pressure) and the total blood flow resistance of cerebral vessels....
