Description
Technical field
This utility model belongs to the medical diagnosis apparatus, is specifically related to a kind of ultrasonic atherosclerosis detector.
Background technology
Along with the change of development of human society and people life style, cardio cerebrovascular affection becomes the healthy main killer of harm humans, is the global public health problem that has a strong impact on people ' s health.Arterial sclerosis, the infringement of vascular function and structure is the beginning motivation system of cardiovascular and cerebrovascular disease, early discovery is the key of preventing cardio cerebrovascular affection with in time stopping arteriosclerosis.The ultrasound inspection methods of vascular lesion has simple and easy to do, and sensitivity is high, and characteristics such as good reproducibility become the focus of scientific research in recent years.
The ultrasound detection of vascular lesion comprises that mainly the morphological change and the function assessment that detect tremulous pulse change; The morphologic detection method comprises that through the arterial vascular arteries intima-media thickness of ultrasound detection, speckle, VPV, drag index, stenosis rate etc. its early prevention to cardiovascular and cerebrovascular disease is worth and has obtained medical circle and clinical extensive approval and utilization.Because arterial vascular function assessment changes early than morphological change, the exploration to arterial vascular changing function detection method is in recent years developed rapidly.Yet in the multiple intra-arterial function detecting method, have only pulse wave conduction speed (pulse wave velocity, mensuration PWV) is the method for the measurement arterial elasticity of relatively generally acknowledging at present, the early prevention that can be vascular lesion provide maybe and scientific basis.Its ultimate principle is: the contraction of left ventricle rhythmicity is injected aorta with blood in the cardiac cycle, and aorta wall produces pulse wave, and pulse wave is transmitted to whole Arterial system with certain speed along blood vessel wall.Obtain pulse wave conduction speed through the time of 2 of one section blood vessels and the body surface of corresponding point-to-point transmission apart from distance that calculates the pulse wave conduction and the ratio of time through the record pulse wave.Computing formula is PWV=L/T.Propagation time (T) is the propagation time of pulse wave between two record positions, shows as the time difference of two waveforms on the figure; Distance (L) is two distances between the detector.Pulse wave was accelerated at endovascular conduction velocity when blood vessel elasticity reduced, on the contrary vascular compliance well then pulse wave in endovascular conduct velocity.Therefore PWV is big, high, the poor compliance of expression arterial stiffness.Otherwise, represent that then blood vessel hardness is low, compliance good.Present ultrasonic employing single-point pulse wave conduction speed (PWV β) measurement method detects arterial vascular PWV.And single-point pulse wave conduction speed PWV β is that reckoning obtains according to numerical value such as hardening parameter β in the blood vessel echo tracking technique (eTRACKING technology); Whether the result can reflect truly that the elasticity situation of tremulous pulse is still waiting clinical further research and confirmation, and this value only can reflect the blood vessel elasticity of test point local intra-arterial.
In a word; Ultrasound Instrument in the past only can be through detecting the partial hardenabilities of assessment tremulous pulse such as arterial vascular arteries intima-media thickness, speckle, VPV, drag index, stenosis rate; Also be merely able to reflection by the blood vessel echo tracking technique of extensive utilization (eTRACKING technology) in recent years and detect the partial blood vessel elasticity of tremulous pulse; Whole hardenability for whole body multistage tremulous pulse can not provide more information, has retrained the range of application of Ultrasound Instrument.
