Abstract
The utility model provides an arteriosclerosis detecting device, comprising a self-adaptive noise canceller. A self-adaptive filter is arranged on the self-adaptive noise canceller and is connected with an accumulator and a noise source sensor that is also connected with an original signal which is connected with a signal source sensor and the accumulator; and collected s1 and n0 or a signal n that is related to the n0 in a certain way are respectively taken as original input and reference input of the self-adaptive canceller. Under the control of a certain self-adaptive algorithm, the signal n related to original blood concentration is filtered so as to generate duplicate output y similar to the n0, and the output y is reduced from original input s plus n0, thus generating system output s plus n0 minus y, namely an output result is similar to a blocking speed s owning to the blood concentration and depositions. The arteriosclerosis detecting device has the advantages of low cost, strong interference resistance and convenience in use.
Description
Technical field
The invention belongs to arteriosclerosis detection technique field, be specifically related to a kind of arteriosclerosis checkout gear.
Background technology
Arteriosclerosis is a kind of non-inflammation pathological changes of tremulous pulse, can make that ductus arteriosus wall thickens, hardening, follows the string, tube chamber is narrow and small.Arteriosclerosis is that its rule normally takes place at adolescence along with people's age increases and the angiopathy that occurs, increases the weight of period, falls ill to person in middle and old age.The male is many than the women, and primary disease increases gradually in China in recent years, becomes one of old people's main cause of death.Arteriosclerotic main type is: 1) tiny arteriosclerosis; 2) medial arteriosclerosis; 3) atherosclerosis.Atherosclerosis is a type common in the arteriosclerosis, for the main diseases of myocardial infarction and cerebral infarction because of.Japan is the state of research and development at first of arteriosclerosis checkout gear in the world, and existing arteriosclerosis checkout gear does not have the rival to occur except that Japan one tame electronics armarium company in the world as yet.Its shortcoming is: the cost height, a little less than the capacity of resisting disturbance, customer group only is confined to specialized agencies such as hospital, and is difficult to overcome arteriosclerosis and detects the traditional mode that still depends on hospital etc.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of arteriosclerosis checkout gear, has higher performance, adopt adaptive approach to make the capacity of resisting disturbance of deal with data that significant increase be arranged, customer group can expand to places such as family and independent social center for the elderly, convenient detection in real time has the advantages that cost is low, capacity of resisting disturbance is strong and easy to use.
To achieve these goals, the technical solution adopted in the utility model is: a kind of arteriosclerosis checkout gear, include an adaptive noise canceller 1, adaptive noise canceller 1 is provided with sef-adapting filter 2, the outfan of sef-adapting filter 2 links to each other with the input of accumulator 3, the input reference input of sef-adapting filter 2 links to each other with the outfan of noise source pick off 4, the outfan of noise source pick off 4 also links to each other with the input of primary signal 5, the input of primary signal 5 also links to each other with the outfan of signal source pick off 6, the outfan of primary signal 5 links to each other with the input of accumulator 3, and the outfan of accumulator 3 also links to each other with the control input end of sef-adapting filter 2.
The beneficial effects of the utility model are:
Because this utility model adopted sef-adapting filter 2, accumulator 3, pick off 4, pick off 6, thus have image data comparatively accurately, under the control of adaptive algorithm the output resultant error can be as far as possible little, can realize arteriosclerotic early stage real-time detection, simple and convenient, characteristics that cost performance is higher.This utility model detects adaptive technique and combines with arteriosclerosis, thereby can realize the early stage inspection of blood vessel, plays the arteriosclerotic characteristics that detect.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to accompanying drawing, a kind of arteriosclerosis checkout gear, include an adaptive noise canceller 1, adaptive noise canceller 1 is provided with sef-adapting filter 2, the outfan of sef-adapting filter 2 links to each other with the input of accumulator 3, the input reference input of sef-adapting filter 2 links to each other with the outfan of noise source pick off 4, the outfan of noise source pick off 4 also links to each other with the input of primary signal 5, the input of primary signal 5 also links to each other with the outfan of signal source pick off 6, the outfan of primary signal 5 links to each other with the input of accumulator 3, and the outfan of accumulator 3 also links to each other with the control input end of sef-adapting filter 2.
Operation principle of the present utility model is:
Because arteriosclerosis is that its rule normally takes place at adolescence along with people's age increases and the angiopathy that occurs, increases the weight of period, fall ill to person in middle and old age.So, individual teenager physical development maturation and health indicator comparatively good in, with special instrument or sensor acquisition blood flow rate at that time, and preserved, be made as n
0In arteriosclerotic prevention subsequently and detecting, person in middle and old age period especially can gather the blood flow rate of this moment again, be made as s
1Along with the growth rhythm of people's life, vascular function especially suffers from arteriosclerotic patient in continuous decline, because blood viscosity is excessive and deposit is too much, can cause velocity of blood flow to reduce, so the blood flow rate s of this moment
1Can regard as mainly is by original blood flow rate n
0The obstruction speed s that causes with haemoconcentration and deposit forms, and promptly can regard s roughly as
1=n
0+ s.Like this, we are with s
1And n
0Or and n
0Xiang Guan signal n regards the original input and the reference input of adaptive cancellation device 2 respectively as in some way, in certain adaptive algorithm (as lowest mean square (LMS) algorithm, recurrence least square (RLS) algorithm etc.) under the control, the n relevant with original haemoconcentration filtered, make its generation be approximately n
0Copy output y, should export from original input s+ n
0In deduct generation system output s+ n
0-y promptly exports the result and is approximately the obstruction speed s that haemoconcentration and deposit cause.
The workflow that it is concrete:
Wherein, establish teenager when healthy, the blood flow actual speed is n
0Gather by special Medical Instruments or related sensor, establishing collection result is n.(be subjected to the restriction of acquisition instrument, n can with n
0Approach with different precision, though can not strictly equate, but relevant); If present blood flow rate is s
1(s
1=s+ n
0, wherein s is haemoconcentration and sedimental obstruction speed, n
0Be teenager when healthy, the blood flow actual speed).
At last, just can make corresponding medical analysis, whether suffer from arteriosclerosis, so that make more accurate inspection and treatment early thereby roughly can judge the patient at s.
