Atherosis degree and lesion degree height correlation coronarius, can more sensitively reflect the situation of systemic arteriosclerosis,
There is critical role in the checkout and diagnosis of cardiovascular and cerebrovascular disease.At present clinic pulse wave conduction speed measurement application mainly for
Systemic arterial entirety PWV is detected, general to use the time for being transferred to ankle artery by radial artery with arm ankle distance divided by pulse wave to prolong
Belated acquisition PWV.However, this method can only obtain systemic arterial integral status.Recent study shows that artery sclerosis is in morning
Phase occurs developing stage and is mainly shown as locality vascular wall lesion, thus local arterial pulse wave conduction of velocity detection to this
The early diagnosis of class disease is significant.Currently for the measurement of superficial arteries local pulse wave velocity generally using high
Frame frequency ultrasonic scanning, detects pulse wave, and estimate that it propagates generation time delay along vessel segment to the vessel segment of long axial direction.According to
The spread speed of the length computation pulse wave of this section of blood vessel.Because ultrasound detection is advised by speckle noise, test gimmick and tube wall
A variety of disturbing factor influences such as whole property, there is larger difference in the pulse displacement for causing detection to obtain, between propagating waveform during delay
Between datum mark be difficult to determine.In addition, ultrasound detection is also present, equipment is expensive, bulky shortcoming.
The problem of for existing, the present invention proposes a kind of superficial arteries local pulse wave velocity detection means, its mesh
Be provides a kind of precision height, small volume, measurement apparatus easy to operate for superficial arteries local PWV detections.
By literature search, do not find relevant with the local pulse wave velocity detection means of technical solution of the present invention identical
Open report.
