Embodiment Construction

[0030] like figure 1 As shown, a high-sensitivity transcranial Doppler blood flow detection system induced by joint stimulation includes an evoked potential detection module 1, a TCD detection module 2, a signal processing module 3, a data analysis module 4 and a display module 5,

[0031] The evoked potential detection module 1 includes:

[0032] The auditory evoked potential meter 11 is used to generate an auditory target / non-target stimulation sequence to stimulate the subject; wherein, the auditory target / non-target stimulation sequence is that the non-target stimulation frequency is 1kHz, the target stimulation frequency is 2kHz, and the target is randomly distributed at Among the non-target stimuli, the number of target stimuli accounted for 20% of the total number of stimuli, the stimulus intensity was 110dB, and the filter bandwidth was 50Hz. When the patient is stimulated externally, the intracranial blood vessels and related tissues of related acupoints will produce...

Abstract

The invention discloses a high-sensitivity transcranial Doppler blood flow detection system induced by combined stimulation, which includes an evoked potential detection module, a TCD detection module, a signal processing module, a data analysis module and a display module. The evoked potential detection module includes an auditory Induced potential meter, quantum state photoelectric emission unit, photoelectric detection component, optical signal processing terminal, capture detection unit; TCD detection module includes probe, ultrasonic transducer, ultrasonic transceiver, ultrasonic sensor; signal processing module includes A signal processing unit, B signal processing unit; the data analysis module includes a data optimization unit, a data fusion unit, a comprehensive analysis unit, and a display module. Under the condition induced by auditory stimulation, the present invention uses cranial Doppler to scan the intracranial blood vessels, and combines the optical signal feedback method of relevant acupoints to comprehensively evaluate the patient's intracranial blood flow, and obtains high-precision, Test results with low error rate and high patient comfort.

Description

technical field [0001] The invention belongs to the technical field of blood flow detection, in particular to a high-sensitivity transcranial Doppler blood flow detection system induced by combined stimulation. Background technique [0002] After severe stenosis or occlusion of the internal carotid artery, collateral circulation compensation will be initiated, and the compensatory ability of each collateral circulation is different. Internal carotid artery stenosis can cause vascular cognitive impairment (VCI), and the degree of damage depends on the degree of stenosis and the patency of collateral circulation after stenosis. Transcranial Doppler (TCD) has a unique effect on the assessment of collateral circulation, and its sensitivity is greater than that of cervical ultrasound, computed tomography (CTA) and magnetic resonance angiography (MRA). ). At present, the research on vascular cognitive impairment is mainly carried out in combination with neck color Doppler ultras...
