Device for analyzing cardiovascular and cerebrovascular characteristics and blood characteristics and detecting method

Abstract

The invention provides a device for analyzing cardiovascular and cerebrovascular characteristics and blood characteristics and a detecting method, belonging to the field of medical equipment. The device comprises a pressure pulse wave sensor, a carotid artery and vertebral artery rheogram inductance electrode, an electrocardiogram inductance electrode, a cardiophonogram sensor, a signal receiver, a main processor and an in-out part. The device can realize the cardiovascular and cerebrovascular noninvasive detection, and biomechanically analyzes each branched blood vessel of the cardiovascular and cerebrovascular system by measuring the blood pressure and the blood flow volume of a left cervical vertebra artery, a right cervical vertebra artery, a cerebrum front artery, a cerebrum middle artery, a cerebrum back artery, a left coronary artery and a right coronary artery, obtains biomechanics indexes such as the elasticity coefficient, the compliance, the blood resistance, the blood flow volume and the like of each branched blood vessel of the cardial blood vessel and the brain blood vessel, has an important significance for the early diagnosis of the myocardial infarction and the cerebral thrombosis by taking as equipment for the cardiography, the magnatic resonance imaging MRI, the CT and the like and supplementary equipment between the TCD and the ECG.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an analyzer and a detection method for cardiovascular and cerebrovascular characteristics and blood flow characteristics. Background technique [0002] Among the existing cardiovascular and cerebrovascular detection devices, the advantage of angiography is that it can visually observe the pathological changes of blood vessels, but its disadvantage is that it needs to inject contrast agent, and the operation of blood vessel invasion is complicated; [0003] Although MRA and FMRI overcome the defects of angiography, their production and diagnosis costs are high, so they can only be used in specific large or specialized hospitals. The disadvantages are: although MRA, FMRI and SPET are different, they are all Can detect blood vessel distribution, blood flow characteristics, and low blood flow areas, but none of these devices can detect blood vessel characteristics; [00...

Problems solved by technology

[0002] Among the existing cardiovascular and cerebrovascular detection devices, the advantage of angiography is that it can visually observe the pathological changes of blood vessels, but its disadvantage is that it needs to inject contrast agent, and the operation of blood vessel invasion is complicated;

[0003] Although MRA and FMRI overcome the defects of angiography, their production and diagnosis costs are high, so they can only be used in specific large or specialized hospitals. The disadvantages are: although MRA, FMRI and SPET are different, they are all Can detect blood vessel distribution, blood flow characteristics, and low blood flow areas, but none of these devices can detect blood vessel characteristics;

[0004] Although the QFM-2000 is a specialized instrument for detecting the characteristics of cerebrovascular characteristics, the ultrasonic waves used to eliminate the measurement error (vertical plane error) caused by the difference in the incident angle of the ultrasonic waves when detecting the blood flow rate of the cervical vertebral artery, which is the basic data of the cerebrovascular characteristics, cannot The measurement error (horizontal plane error) related to the direction of the blood vessel and the operation part of the ultrasonic operator has not been eliminated, resulting in large errors in the measurement data, and the measurement accuracy cannot be guaranteed;

[0005] Invasive examination methods such as catheterization for cardiac examination have the advantage of being able to visually observe the pathological changes of the blood vessel itself, but require complex invasive operations on the blood vessel, and the disadvantage is that 20-40% of the examinees are non-surgical Although it has high clinical significance, it can only be performed in specific hospitals due to the high cost of production and diagnosis;

[0006] Therefore, the problem of assessing the coronary arteries in a non-invasive way has received great attention, but this is a medical problem, due to the very complex structure of the blood flow in the left coronary artery, detection of pulse pressure waves and zero blood flow driving blood flow in the coronary arteries The problem of pressure has become an unresolved problem
