CEREBROVASCULAR ANALYZER

摘要

The present invention relates to a cerebrovascular analysis system which enables early diagnosis of various incurable cerebrovascular diseases such as cerebral thrombosis by measuring an elastic coefficient, blood vessel compliance, blood flow resistance, and blood flow in each cerebrovascular branch. The measurement is achieved by biomechanically analyzing blood vessels in the brain using an electrocardiogram, phonocardiogram, electroencephalogram, pulse wave, and ultrasonic doppler signal as basic data in order to measure biomechanical properties and blood flow properties of blood vessels in the brain for the diagnosis of cerebrovascular diseases.

主权项

1. A cerebrovascular analyzer comprising:
a bio-signal measurement system including a bio-signal measuring sensor unit which comprises an electrocardiogram (ECG) sensor, a phonocardiogram (PCG) sensor, an accelerated plethysmogram (APG) sensor and an ultrasonic sensor, and a bio-signal reception and process unit which is connected to each of the sensors of the bio-signal measuring sensor unit for receiving and processing bio-signals measured by the sensors; and an analysis indicator calculation system including a main processing unit which is connected to the bio-signal reception and process unit for communicating and calculating biodynamic indicators of a cerebrovascular system from the bio-signals, an input unit which is connected to the main processing unit for receiving control commands of a user, and an output unit which is connected to the main processing unit for displaying the calculated results, wherein the APG sensor comprises a pressure sensor electrically connected to the bio-signal reception and process unit by a sensing read line, the pressure sensor being a carotid artery pulse wave sensor to obtain an APG waveform from a left or right carotid artery; wherein the main processing unit is programmed to calculate the biodynamic indicators from basic data including a cerebrovascular pressure curve, a systolic area and a diastolic area of the cerebrovascular pressure curve and an cerebrovascular blood flow volume; and wherein the cerebrovascular pressure curve is synthesized with the bio-signals of the bio-signal measurement system, the bio-signals comprising at least the APG waveform measured by the carotid artery pulse wave sensor.
