Problems solved by technology

However, because the parameter analysis requires more blood flow information of intracranial cerebral vessels: in addition to the carotid artery blood flow information, it also needs to accurately detect all the blood flow information of the anterior, middle, posterior and vertebral arteries of the brain, otherwise it cannot Carry out whole brain analysis, and according to the current technical level of TCD, not all people's intracranial blood vessel flow velocity information can be accurately measured, which also limits the further clinical promotion of this type of cerebral circulation analyzer to a certain extent

Embodiment Construction

[0055] Further illustrate the present invention below in conjunction with accompanying drawing.

[0056] see figure 1 , the simple and convenient analysis method of middle cerebral circulation hemodynamics of the present invention, according to the characteristic of cerebral Willis circle, cerebral arterial system is divided into three parts of left front, right front and rear part; A flow resistor describes the anterior communicating artery, and connects the left and right carotid artery systems as a whole. A flow resistor is used to simulate each segment of carotid artery and vertebral artery, and on this basis, an 11-unit equivalent circuit network of cerebral circulation hemodynamics is established. Model.

[0057] In the 11-unit equivalent circuit model, a flow resistance R is used at the inlet port of the left carotid artery C1 Simulate carotid resistance, followed by a parallel connection to simulate left anterior cerebral artery compliance flow volume C C1 and the f...

Abstract

A simple analysis method for the cerebral circulation hemo-dynamics includes such steps as dividing brain into front left, front right and back parts according to the cerebral Wills ring, creating the network model of equivalent circuit of hemo-dynamic units and relative control equation, finding out their blood flow, filled blood amount and pre-compensation and calculating their hemo-dynamic parameters such as critical pressure, dynamic resistance, etc. Its instrument is also disclosed.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a simple method for analyzing cerebral circulation hemodynamics and an analysis instrument designed according to the method. Background technique [0002] Cerebrovascular disease is one of the three major diseases that seriously threaten human health. The disease has the characteristics of high incidence, high disability rate, high mortality rate and high recurrence rate, and is the main cause of death and disability in middle-aged and elderly people. A large number of clinical and animal experiments have shown that in the early stage of many cerebrovascular diseases, the parameters of cerebrovascular dynamics often have significant changes, and these dynamic changes are often significantly earlier than the morphological changes. For those with abnormal early kinetic parameters, their kinetic parameters may return to normal after active prevention and treatment. Th...
