Embodiment Construction

[0041] Further illustrate the present invention below in conjunction with accompanying drawing.

[0042] see figure 1 , figure 2 , it can be seen that the cerebral hemodynamic analysis method of the present invention comprises the following steps: firstly, the continuous wave Doppler blood velocity waveform detection module is used to detect the blood velocity waveform and the value of the carotid artery: V (t), for the velocity waveform and numerical values ​​for data processing to obtain the maximum flow velocity Vmax, the minimum flow velocity Vmin and the average flow velocity Vmean within a cardiac cycle; The blood vessel diameter D; the arm-type electronic blood pressure measurement module is used to detect the systolic blood pressure Ps and diastolic blood pressure Pd of the human body; then the corresponding cerebral hemodynamic parameters can be calculated according to the detected data through formulas (1) to (4).

[0043] see image 3 , The cerebral hemodynamics...

Abstract

The invention provides a method and apparatus for brain blood flow dynamic analysis, wherein a continuous wave Doppler blood flow rate waveform detecting module is utilized to carotid artery blood flow rate waveform and value, a pulse type supersonic carotid artery caliber detecting module is employed to detect the blood vessel diameter of the carotid artery, an arm type electronic blood pressure measurement module is used to obtain the human body blood pressure readings, and a simplified method is employed to calculate and analyze the cerebrovascular dynamic parameters. The invention can substantially improve the detecting and analyzing speed for the brain hemodynamic parameters, and greatly reduce the volume of the apparatus.

Description

technical field [0001] The invention belongs to the field of medical technology, and is a simple method and instrument for analyzing cerebral hemodynamics. 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. Cerebrovascular lesions first cause cerebral circulation disturbance, resulting in ischemia of brain tissue in some local areas, which in turn leads to brain cell death. [0003] 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...
