Description

A kind of big-and-middle artery local pulse wave velocity detection probe of internal deep layer
Technical field
The present invention relates to a kind of internal big-and-middle artery local pulse wave velocity detection probe of deep layer, category biomedical engineering inspection Survey field.
Background technology
Cardiovascular and cerebrovascular diseases caused by arteriosclerotic disease such as coronary heart disease, headstroke etc. have turned into the whole world mankind because dying of illness The main cause died.Research shows that pulse wave velocity is directly related with Degree of arteriosclerosis, and Degree of arteriosclerosis, which increases, to be made Obtain pulse wave velocity to rise, be an independentpredictor of cardiovascular and cerebrovascular diseases.Accurate measurement pulse wave velocity is to artery sclerosis Class disease, and its cardiovascular and cerebrovascular disease early diagnosis thus triggered are significant.
The image check of the big-and-middle arterial diseases of human body deep layer such as current coronary artery and diagnosis are mainly made by coronary artery Shadow.This kind of method is disadvantageous in that：Equipment is expensive, complex operation.Understand and diagnose coronal by noninvasive method early stage The degree of arterial disease turns into the emphasis of research.It is big to diagnose the human body deep layer such as coronary artery by measuring local pulse wave velocity The occurrence and development of middle arteriosclerotic lesion are a kind of direct non-invasive methodses.The survey of the local pulse wave velocity of existing coronary artery Amount mainly by pulse wave propagation time on high frame frequency ultrasonic scan coronary artery section specific range, with fixed range divided by Propagation time obtains local pulse wave velocity.But the pulse wave detection propagated is influenceed larger by external interference, the base between waveform It is difficult to accurate determination between punctual, causes the estimation of pulse wave velocity to produce larger error.The present invention proposes that a kind of internal deep layer is big Middle artery local pulse wave velocity detection probe, its object is to avoid interfering between pulse wave in measurement process, is carried The accuracy of high fiducial time.
By literature search, do not find to disclose report with the technology of the present invention identical.
The content of the invention
It is an object of the invention to overcome the deficiency of existing detection pulse wave method, it is to avoid in measurement process between pulse wave Interfere, the accuracy of fiducial time is improved, so as to provide a kind of inspection of internal deep layer big-and-middle artery local pulse wave velocity Probing head.
The big-and-middle artery local pulse wave velocity detection probe of internal deep layer of the present invention, including：Play a supporting role in protection Probing shell (1), the rectangle entrant sound face (5) being placed at the top of probing shell (1) is placed in rectangle entrant sound face (5) center Ultrasonic transducer linear array (7), is placed in the first electrode (4) of the side point midway of rectangle entrant sound face (5) four, second electrode (6), the 3rd Electrode (8) and the 4th electrode (9), are placed in the damping backing (2) of rectangle entrant sound face (5) encapsulation behind, the electrode letter of transmission signal Number line (3) and ultrasonic signal line (10), the electrode signal cable being connected respectively with electrode signal line (3) and ultrasonic signal line (10) And ultrasonic signal cable (11) (12)；Wherein, be placed in (5) two, rectangle entrant sound face short side point midway first electrode (4) and 3rd electrode (8) spacing is not less than 30mm, and the second electrode (6) of two long side point midway and the 4th electrode (9) spacing be not small In 10mm.
Ultrasound and electrode detection measurement used in the present invention are publicly-owned technology；Using to electrode, supersonic array, matching The devices such as layer, damping backing, signal wire are market purchase.
The advantage of the invention is that：Simple in construction, easy to operate, local pulse wave velocity measurement error is small, precision is high.System One makees time reference using the starting of human body spontaneous electrocardiosignal, it is to avoid interfering between pulse wave in measurement process, improves Pulse wave propagation delay time estimated accuracy, effectively improves the accurate of the big-and-middle artery local pulse wave velocity detection of internal deep layer Property.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
Fig. 2 is application example schematic diagram of the present invention.
Embodiment：
The present invention is described in further detail below in conjunction with the accompanying drawings.Ultrasound and electrode detection measurement used in the present invention is equal For publicly-owned technology.
As shown in figure 1, the big-and-middle artery local pulse wave velocity detection probe of internal deep layer of the present invention, including：Play branch The probing shell 1 of protective effect is supportted, the rectangle entrant sound face 5 at the top of probing shell 1 is placed in, is placed in the center of rectangle entrant sound face 5 Ultrasonic transducer linear array 7, be placed in the first electrode 4, second electrode 6, the 3rd electrode 8 of the side point midway of rectangle entrant sound face 5 four And the 4th electrode 9, the damping backing 2 that rectangle entrant sound face 5 is encapsulated behind is placed in, the electrode signal line 3 and ultrasound for transmitting signal are believed Number line 10, the electrode signal cable 12 being connected respectively with electrode signal line 3 and ultrasonic signal line 10 and ultrasonic signal cable 11；Its In, the first electrode 4 and the spacing of the 3rd electrode 8 for being placed in the 5 two short side point midways in rectangle entrant sound face are not less than 30mm, two long The second electrode 6 and the spacing of the 4th electrode 9 of side point midway are not less than 10mm.
By taking the detection of arch of aorta pulse wave velocity as an example, detection process process is as follows：First, detected object, which is taken, lies on the back Position, takes off upper outer garment and exposes chest.Detection operating personnel take medical ultrasonic coupling agent to be applied to the detection object heart arch of aorta pair Answer skin of chest；Start ultrasonic probe, the acoustic beam for adjusting probe test position and direction reaches heart actively through rib interval Arcus haemalis, as shown in Figure 2.At the same time, first electrode 4, second electrode 6, the 3rd electrode 8 and the 4th electrode 9 receive human body spontaneous Electrocardiosignal, and it is sent to signal amplification and filtration module handles accordingly, then obtain two groups of independences through arithmetic superposition Electro-cardiologic signal waveforms.By the ultrasonic radio frequency echo-signal received feeding ultrasonic imaging processing, and extract arch of aorta section propagation Pulse displacement train wave.The time reference point for determining sequence pulse displacement ripple is originated with electrocardio, pulse wave time delay is calculated. Arch of aorta local pulse wave velocity is calculated finally according to detecting distance, and the pulse wave velocity for taking interval of time to measure is made It is average, obtain last testing result.
