Embodiment Construction

[0030] The present invention will be further described below in conjunction with drawings and embodiments.

[0031] A non-invasive detection system for intracranial blood circulation disorders based on network topology analysis, such as Figure 5 As shown, the specific usage method is:

[0032] 1) if figure 1 As shown, a patch pressure sensor was placed on the left carotid artery of the subject to be measured, figure 1 Middle measurement point ③, and respectively place a pair of cuff pressure sensors at the left and right ankle joints of the lower limbs, figure 1 In the middle measurement points ② and ④, the method of synchronous measurement is used to measure the three measurement points.

[0033] 2) Obtain the pulse waveforms of the three measurement points. Based on the pulse wave theory and the principle of the oscillometric method, the analysis host calculates the physiological parameter values ​​at the three measurement points respectively; these parameter values ​​sh...

Abstract

An encephalic blood circulation disturbance nondestructive detection system based on network topological analysis comprises a carotid artery measuring unit, a lower limb artery measuring unit, a signal collection processing control unit and an analysis host, the encephalic blood circulation disturbance nondestructive system is free from directly detecting the brain, only the pulse waveform on the surface of the lower limbs and the neck is measured, the encephalic blood circulation disturbance can be indirectly judged through corresponding equivalent conversion and formula calculation as well as contrast to the threshold value, and the limit of the existing detection device that the existing peripheral blood vessel measuring technology cannot be applied to the judgment of the encephalic blood circulation disturbance can be overcome.

Description

technical field [0001] The invention relates to the field of biological signal measurement and analysis, in particular to a non-invasive detection system for intracranial blood circulation disorder. Background technique [0002] At present, intracranial blood circulation disorders are mainly detected by cerebral blood flow diagram, cerebrospinal fluid extraction, cerebral angiography, CT and magnetic resonance (MRI). Although these methods have their own advantages, they are all used in the diagnosis of cerebrovascular diseases. It is performed in the late stage, when the patient has more serious symptoms of cerebrovascular disease, and these methods are either invasive or expensive to examine. In the current clinical application at home and abroad, there is a lack of a diagnostic method and instrument that can quickly screen out patients with cerebrovascular diseases in the early stage of diagnosis of intracranial blood circulation disorders, and initially give the type and...
