Above-mentioned two kinds of technology are in clinical practice, it is all the bloodstream blocking arteries external force (air pressure) of person under inspection side limbs (upper limb) being carried out to certain hour, another limbs do reference, then pressure relief blocks suddenly, then the hemodynamic change of comparative observation person under inspection left and right sides limb artery.
The instrument of above-mentioned the first pressure sensing technology (PAT) is adopted usually by pressure cuff, the brachial artery surveying person under inspection side to be imposed to the pressure of 200 ~ 300mmhg, suddenly pressure relief again after 5 minutes, observes the change of its fluctuating signal waveform before and after exerting pressure to person under inspection's both upper extremities tip pressure transducer fingerstall.
The detection method of this kind of PAT has following shortcoming: (1) exists the impact being subject to ambient environmental factors and autonomic nerve; And have the single problem of Detection Information (2), generally can only gather the local message of regulation, if collected finger exists recessive vascular lesion, erroneous judgement may be caused to cause mistaken diagnosis.
And adopt the instrument of above-mentioned the second ultrasonic technique (FMD) to be also adopt the far-end of above-mentioned means to person under inspection side brachial artery to exert pressure, suddenly pressure relief again after 5 minutes, observes brachial artery go out the change of artery structure at front and back ultrasonic probe of exerting pressure simultaneously.
The detection method of this kind of FMD its need the operator of well-trained ultrasonic image specialty, blood pressure cuff position, tangent plane are chosen and pressing dynamics of popping one's head in all can have an impact to result;
Therefore, research and development one can provide that quantity of information is more abundant, image is directly perceived, data are considerable, flexible and convenient to use, simple to operate and extremely urgent to the checkout gear that the technical requirement of operator is not high.
