Description
Affiliated technical field:
The invention belongs to medical material and equipment, particularly be the pulse wave spectrum sensor-based system of using about tcm diagnosis.
Background technology:
Pulse wave spectrum is the method that diagnoses the illness of tool Chinese culture characteristic, and practical experience accumulation and the exclusive theoretical system in more than 2,000 year are arranged, and deep scientific meaning and long-tested objective actual effect is quite arranged, and stand upright in the woods of world medicine.Feeling the pulse is visited a patient, in conjunction with the comprehensive analysis of the data gained by the four methods of diagnosis of hoping, hearing, ask, and the discrimination of arteries and veins card, be the regular works of Chinese physician's diagnosis and treatment illness, be the basic training of the traditional Chinese medical science.This direct, rapid, safe, undamaged diagnostic method, can system comprehensively understand human life state and illness situation thoroughly, be a wonderful work of world medicine, have distinct green medical features, be considered as 21 century the most vital " alternative medicine " by western medicine.But because the rich connotation of pulse wave spectrum, change all the time, technology is difficult, it is easy to be proficient in the gangster, theory and the understanding that still rests on so far clinically since ancient times, feel the fingering and the sensitive level of pulse signal entirely by the person's of feeling the pulse finger tip, and rely on Chinese physician's experience and comprehensibility to differentiate cognitive, the puzzlement that " understand by thinking, be difficult to sensible " arranged.Not only western medicine can't be understood pulse this just reacts the signal of heart and Arterial system, the traditional Chinese medical science how can be from the area on the wrist over the radial artery where the pulse is felt for diagnosis of trivial wrist radial artery, three ones of cun,guan,chis with floating, in, heavy each layer position, know whole body vital organs of the human body functional statuss, to this, Traditional Chinese medical theory is also just from the internal organs meridians, and generally explaination on the qi-blood-body fluid operational relation is difficult to disclose its essence with modern scientific theory.Especially the area on the wrist over the radial artery where the pulse is felt for diagnosis distributes the basis of internal organs, and right-hand man's cun,guan,chi distributes the opinion of internal organs to differ for a long time, and is unable to decide which is right, all have proposal do not have with, maintain judgement by experience entirely.For pulse and sick relation of waiting, the time have pulse condition and disease, card, disease to be difficult to the unified phenomenon of coincideing, the arteries and veins card separation of making a diagnosis on the basis of symptoms and signs instead of that of pulse condition or making a diagnosis on the basis of pulse condition instead of that of symptoms and signs is just arranged, and the choice difficulty that is difficult to follow is arranged.Also because of being subjected to system of enfeoffment reason to teach constraint in history, with learned biased, and the reason that ancient times, the pulse-taking principle difficulty was driven, " all over the diagnostic method " etc. of embodying traditional Chinese medical science organic conception method with being good at loses, and only spread single " the area on the wrist over the radial artery where the pulse is felt for diagnosis method ".Everything all becomes the traditional Chinese medical science and fluctuates for a long time over the past thousands of years, be difficult to grow with each passing hour and improve the restriction bottleneck of development, press for from the theoretical method to the technological means on, obtain the breakthrough and the reconstruct of epochal character, it is objective and accurate that pulse wave spectrum is become, the not damaged modern diagnosis technology that safety is fast.Even to this day, when science and technology of new generation so develops rapidly, when from modern life science, systematic science, information science, biochemistry, molecular biology, hemodynamics, hemorheology, diagnostics, and the physiology on basis, subjects such as psychology, pathology, anatomy, with the omnibearing visual angle of multidimensional, multi-level when re-recognizing life mechanism, just know that human body is a super huge system of being made up of different levels and architectural feature of complexity, be one in order and and the harmonic motion organic whole, vibrating.And based on beating of this core drive organ of heart, blood is the carrier of material, energy and information, by blood vessel and each histoorgan of whole body, highly compatible on time domain and frequency domain, harmonious conduction coupled resonance effect is arranged between reciprocity, form the main rhythm and pace of moving things of human life.Simultaneously, also know that human body still is electromagnetic compatibility system of exquisite complexity, meridians are that electromagnetic wave vibrates in order, and the electrochemical gradient that causes thus changes the regulation and control passage that changes with neuro humor, from outward appearance to inner essence to each hierarchical system contact conduction.This two aspect has been together to form the information system of reaction physiological pathology of human body, is expressing the operation conditions of each histoorgan, is regulating and control the metabolism of life, reaches the mutual hair growth promoting of each several part in the system, the dynamic stability relation of mutual restriction.Very intelligent Ancient Chinese is for the ancestor, find very early, at the radial artery of two wrist radius inboards and the lung meridian of meridians, be parallel to this special arch of aorta anatomical structure place, and on the arterial of each shallow table of whole body, available finger presses to be known under the skin displacement facial disfigurement, the physiological and pathological state pulse condition aggregate information of direct reaction human life.Thereby form the theoretical method system of pulse wave spectrum uniqueness comprehensively.Hence one can see that, when using to the finger feeling the pulse with the finger-tip that presses and vibration sense is very responsive, at random flexibly at two wrist the area on the wrist over the radial artery where the pulse is felt for diagnosis places, lift, seek, push away, compete, with, suitable, during fingering such as contrary changes, after being subjected to different exerting pressure from Artery Vein, under the variation of skin displacement face, in the counteracting force relation to finger, the depth, thickness, power, frequency, the rhythm and pace of moving things, length, the string that perceive pulse condition soften, slide model set information such as puckery; In this group dynamic composite type blood flow resistive kinetics pulse signal, on its all directions and the arteries and veins position of respectively exerting pressure different, no matter be the pressure wave of radial variations, the still flow and the speed wave of axial hypertonic are all being carried the physiological and pathological information of each histoorgan.Especially can be from the parasitic harmonic wave component that is attached to main ripple, sick position, characteristic of disease, the cause of disease, pathogenesis and patient's condition situation in obtaining different harmonic components and specific internal organs being corresponding; This be pulse condition on time domain and frequency domain, promptly the information characteristics that changes on time and the space is embodying a concentrated reflection of pulse wave spectrum " position, shape, gesture, number " elemental; And the radial artery place is because the anatomical features of head of radius makes the tangible shallow tableization of the intermediary GUAN spot vascular of the area on the wrist over the radial artery where the pulse is felt for diagnosis, CUN before it is the shape that sink, thereafter it is darker that chi subordinate falls into, and formed the existence of the arch of aorta, just have with food, in, the unknown three sensation differences that refer under the displacement surface distortion of the application of forces; The strong and weak difference of this each one of arteries and veins, the state that has reflected each histoorgan locus in vivo and fortuneization itself, be formed on the relation that reactions vary on arteries and veins position and each aspect, there are the heart, lung, gallbladder, spleen, stomach to divide due to a cun GUAN spot, kidney, bladder, intestine and small intestine adhere to separately due to chi portion, Here it is, and the essence place of waiting is divided in cun, guan and chi, three places at the wrist where the pulse is usually taken internal organs location, and is confirmed by a large amount of practices; From then on as seen, how rich and varied the pulse condition information that this refers under the abdomen is, track is wrong complicated, and it is very very difficult perception and resolution, is the difficult place of the technology of feeling the pulse; For the Dialectic Relationship of pulse condition with disease, card, disease, must be function of human body or shape matter ANOMALOUS VARIATIONS from disease, card is body conditions of the current stage in lysis, disease is that comprehensive pathomechanism of disease clinical manifestation is familiar with; Generally speaking, arteries and veins and they are to meet each other accordingly, and it is proprietary especially to demonstrate,prove this Chinese medicine, with the changes of function is the summary of main typing, all the more so; But some specific conditions are formed down, arteries and veins card separates contrary performance also the time, this is because in the disease progression change procedure, the trickle difficulty of the pulse condition of quantitative change to qualitative change is examined, with body under autonomic balance is adjusted, have the extremely reverse expression of hypercorrect pulse condition, this all needs from improving pulse condition to be detected resolution, and comprehensive dialectical Analyses cognition is judged; From the above, with modern Chinese medicine pulse-taking mechanism explaination, traditional pulse wave spectrum over the past thousands of years can be brought up on the brand-new science aspect; When with high-tech sensing detection technology, with the systematic analysis discrimination method, just can obtain the breakthrough developing of New Times, and, develop again with the innovation of high-tech art the traditional Chinese medical science " all over the diagnostic method " of losing disconnected thousand.
Aspect the objective instrumentation of pulse wave spectrum, many experts and scholars of China and foreign countries are carrying out actively benefiting our pursuits for a long time, and as far back as mid-term in 19th century, the Frenchman has just invented the pulse wave tracer, goes out the image of pulse with avatars.Along with developing rapidly of modern science and technology, since the 1950's, carried out the development of pulse-taking instrument and device both at home and abroad again in many ways, electropulsograph is developed in Japan, Korea S, the U.S., Germany and Taiwan all someone, carries out the time and frequency domain analysis of pulse condition.The domestic research that also begins this respect this moment, the BYS-14 of Pekinese type four leaders resemble electrocardiogram equipment, the MTY-A type pulse instrument in Shanghai etc. is developed. but all owing to the limitation that is subjected to traditional Chinese medical science mechanism of pules condition understanding, the physiological and pathological information that reaches each histoorgan is how to be reacted to wrist radial artery place, where the cun,guan,chi of cunkou pulse divides waits the internal organs foundation, floating, in, how the taking the pulse heavily arteries and veins obtain various pulse condition informations again, all lacks clear and definite theoretical direction.Thereby resistive stochastic and dynamic and pulse wave spectrum sensor-based system simplification complicated and changeable, restricted by crucial pulse image sensor technical merit, long-term how adopts inflexible single or multiple mechanical type probe to detect pulse condition, this obviously and the certificate finger that softness arranged and be rich in elastic force press down to obtain to gather pulse signal far apart.Though also used electronics and Intelligentized Information means, all because of the deficiency of pulse image sensor technology and method, be difficult to obtain as true abundant pulse signal as the finger, everything does not all exceed the detection category of heart and blood flow circulatery system dynamics, make some electropulsographs of institute's development and production, pulse instrument rests on the very basic stage more, can only do a little teaching demonstrations, or the instrument of some basic research, with the meticulous collection research that can reach arteries and veins spectrogram picture, objective and accurate diagnosis instructions for use clinically, a certain distance is still arranged, thereby be difficult to apply, cause the traditional Chinese medical science, reach by rule of thumb and come to realize the disconnected disease of feeling the pulse still with traditional finger method sense of touch pulse condition in ancient times, indagation with the brand-new modernized diagnostic instruments of doctor trained in Western medicine greatly differs from each other.Thus, all be anxious for to pulse wave spectrum theoretical with method on, obtain epoch-making breakthrough, calling the modernized practical traditional Chinese medical science feel the pulse instrument and system and device appearance.
Summary of the invention:

The core of this technical method, be whippy polymer-function material polyvinylidene fluoride (PVDF) piezoelectric membrane with personalizing soft, be designed to refer to planar array aggregation type touch-pressure sensation pulse image sensor, gather physiological pathology of human body dynamic composite type blood flow resistive kinetics pulse signal as finger; Cooperate with pcs signal analyser and demonstration recorder again and can realize accurate pulse-taking purpose.
The present invention is on the basis that modern Chinese medicine pulse-taking theory is reconstructed, with high-tech bionic type " artificial skin " method for sensing, on material and configuration, the characteristics that real simulation traditional Chinese medical science finger is felt the pulse, Computerized intelligent signal analysis technology in addition, constitute complete modern pulse wave spectrum device, as figure and the Quantitative Study and the clinical syndrome differentiation diagnosis use of Chinese medicine pulse collection of illustrative plates.The core of this technical method, be whippy polymer-function material polyvinylidene fluoride (PVDF) piezoelectric membrane with personalizing soft, be designed to refer to planar array aggregation type touch-pressure sensation pulse condition sensing receiver, gather physiological pathology of human body dynamic composite type blood flow resistive mechanics pulse signal as finger.The thoughts and feelings function of finger can be reproduced and surmount to its sensitive and emulation, can be with the rational perception and the maneuver experience of pulse wave spectrum, and vivid and express quantitatively, be that the pick off of compositions such as other mechanical type metallic elastic component, strain beam is difficult to reach.Bionic type " artificial skin " sensing is subjected to method, not only be convenient to detect the pulse condition at wrist the area on the wrist over the radial artery where the pulse is felt for diagnosis place, and the construction features of the finger boat of can feeling the pulse, the mode that line connects, at each shallow table tremulous pulse place roaming sense of touch fluctuating signal of whole body, the ancient Chinese medicine " all over the diagnostic method " of losing 1,000 sexcentenaries is carried out the modernization distillation.The combination of " the area on the wrist over the radial artery where the pulse is felt for diagnosis method ", " all over the diagnostic method " by the whole blood vessels situation of change of the whole body seen clearly of point and face, is that comprehensive, stage construction is held whole and each local message, to disease position, qualitative, quantitatively make a decision the important method means of pathogenesis.The typical 28 kinds of pulse condition informations of traditional pulse wave spectrum can not only be obtained comprehensively, and one-to-one relationship sick and arteries and veins can be realized.Again through pulse signal analyzing and processing based on computer, on display screen and print record instrument, the cun, guan and chi, three places at the wrist where the pulse is usually taken position that obtains the area on the wrist over the radial artery where the pulse is felt for diagnosis place of image and the two dimension and the three-dimensional pulse condition oscillogram at systemic arterial place, pulse amplitude and arteries and veins position variation relation figure, sering aspect graph and relevant character etc.And carry out the time frequency analysis of signal on this basis, and especially to detecting the frequency fine fractional analysis of special difficult and complicated illness, and each information is gathered editor, obtain the pulse condition collection of illustrative plates of series, become the foundation of the objective and accurate judgement of various diseases.
The present invention be directed to typical pulse wave spectrum " the area on the wrist over the radial artery where the pulse is felt for diagnosis method " realizes with " all over the diagnostic method " design studies, the whole system device is made up of three parts, be the pulse condition diagnostic table of core and the pulse signal analysis and the demonstration recording section of computer promptly based on bionic type " artificial skin " pulse image sensor.Be provided with feeling the pulse of two groups of finger-shaped structures in the front of diagnostic table and refer to the boat probe, top A group be three by cun,guan,chi three positions, the fixed automatic pressurization feeling the pulse sensing mechanism of setting, " the area on the wrist over the radial artery where the pulse is felt for diagnosis method " of carrying out hands radial artery place detects.Its pulse pressure pressurizes automatically with segment increasing or arbitrary value form in 0-250 gram scope, detect floating, in, pulse signal under the pulse pressure of heavy each layer position.Three of following B groups, be to refer to that with the pulse-taking of top A group the boat probe is the same, just connect roaming type for line, refer to that boat is provided with fingerstall, can with Chinese physician's food, in, on the third finger, not only can carry out " cunkou pulse " touching, pressing and searching with fingers for pulse feeling, push away, compete, with, fingering such as suitable, contrary, the application of force is touched and is examined pulse condition at random, and can, do " all over the diagnostic method " roaming type pulse condition thoughts and feelings with all maneuvers as above to each site of pulsation of the artery of whole body.Simultaneously, on the diagnostic table and be provided with eye-catching pulse pressure LCDs, the synchronous numerical value that is showing pulse pressure.In the bottom surface that refers to boat, polyphosphazene polymer vinylidene fluoride (PVDF) the piezoelectric membrane sensing element as people's skin is housed.The PVDF piezoelectric membrane is after roll extrusion stretches, make the alpha type crystal in the thin film become the β type crystal structure, this is a kind of polar crystallite, again after the processing on the High Level DC Voltage 500KV/cm under the uniform temperature, thin film just obtains the spontaneous polarization function, and stronger piezoelectric effect is arranged, when external force of bearing certain orientation or distortion, the plane of polarization of material will produce certain charge signal.This " artificial skin " is according to good gentle elasticity is arranged, and be in light weight, the bulk resistor height, and mechanical strength is good, and frequency response is wide, and thickness has only tens microns.And planar, linear array shape, the face battle array shape form that is coated with metal electrode made in design at the signal collected various requirement of pulse-taking, reaches height that the anthropomorphic dummy who is really true to life the refers to face elasticity touch-pressure sensation feature that softens.Especially be exposed teleneuron as application on human skin by some specializations, and teleneuron and the common special corpusculum that forms of some tissue: the point-like set district of Mei Shi ball, Pasteur's ball, when being subjected to pressing with deformation displacement, it is the same to produce touch-pressure sensation mechanism, when the PVDF of several forms piezoelectric membrane, behind the compound composition pulse condition sensing element, just can collect various pulse signals.Use the planar PVDF piezoelectric membrane after polarizing, can collect and contain DC component 0-250 gram pulse pressure piezoelectric signal, and the 0-50 of alternating component gram pulse biodynamics signal.Expressing the life of human body, under the periodicity contraction and the diastole master rhythm and pace of moving things with this working organ of heart, the periodic swinging motion of the blood that causes, blood pressure and blood vessel wall, form the typical biodynamics phenomenon of blood circulation, had a change, deformation, gesture to become and count the comprehensive pulse condition feature of change.Especially in tremulous pulse, heart beating harmonic wave and the different harmonic components that each organ resonates have been formed complete pulse frequency spectrum jointly.Be that these harmonic components and specific organ are producing corresponding relation, reacted the special signal of each organ physiological and pathological, so can from the variation of pulse wave frequency spectrum, know the functional status situation of each organ.But with regard to concrete feeling the pulse, the periodic swinging complex signal feature of pulse condition, be to change with radial pressure wave in the arteries and axial flow speed waveform attitude, when pulse pressure to vary in size, when forming kinestate conversion and the dynamic balance relation under the resistive, the partial discharge speed wave converts pressure wave to and changes, pressure and vibration thoughts and feelings under the finger face have been formed jointly, obtain all pulse conditions from face and refer to feel signal characteristic: the depth of arteries and veins position, the waveform of pulse condition, the power of pulse, the size of pulse amplitude, the frequency of pulse, the rhythm and pace of moving things of pulse, the length of arteries and veins body, the form of vascular, and little the shaking of high frequency of reacting psychological pulse condition.That this has just that single pulse condition characterizes is floating, heavy, empty, real, large and small, sliding, puckery, string, late, number, short, knot, generation, long and short, and the combination pulse condition characterize slow, big vast, little, tight, moisten, weak, remove from office, firm, move, lie prostrate, traditional twenty-eight kinds of pulse condition such as diffusing, onion.But these all are typical and the most basic pulse condition morphologies, and it but is that ever-changing, in different poses and with different expressions, different disease just presents different pulse condition that concrete abnormal pulse resembles.
For obtaining the detection of this all pulse condition, with PVDF piezoelectric membrane sensing element, that special design is made is planar, linear array shape, three kinds of forms of face battle array shape.The planar piezoelectric membrane of PVDF is especially as the characteristics as the finger face, when experiencing pressure and distortion, just the electric charge that generation is directly proportional with pressure and deflection on plane of polarization forms the touch-pressure sensation signal and exports.Because its contact surface is big, just can obtain complete quiet dynamic pulse manifestation information.When the position of respectively pulsing at the cun,guan,chi of wrist portion and whole body, and floating, in, on the taking the pulse heavily pulse pressure layer plane, can collect serial pulse signal with various fingering.After pretreatment and the conversion of signals collecting link, become digital signal, wherein the pulse pressure value just is presented on the ad hoc LCDs at random; The dynamic digital signal that the pulse power of beating produces, be input to and carry out analyzing and processing in the computer, also obtain the most primary pulse condition oscillogram at random on computer display screen, and note the wave form varies shape under the best pulse pressure emphatically, it is reacting the overall picture of main pulse condition information.PVDF linear array shape piezoelectric membrane be according to the finger mask perception and the vascular morphological function of differentiating about 1mm to be arranged, and the linear array sensing form of certain width and spacing is made in design, pay close attention to or best pulse pressure under, obtain sering width and aspect graph picture.PVDF face battle array shape piezoelectric membrane, it is the multiple spot bit array form of cutting apart arrangement in length and breadth, because the area of its every some position is little, frequency response is good, and sensing is good, just can sensitive propagated sensation in the pulse condition high frequency and the little signal that shakes on pressure wave and the speed wave, this extremely helps the refinement analysis of pulse condition frequency spectrum, with catch some faint special pathological changes signal and morbid state of mind signals, simultaneously Integral Processing is carried out in the each point position after, more can accurately hold whole pulse condition information feature.Detect by the pulse condition that these point, line, surface are comprehensive, multi-level, just can obtain whole pulse condition Dynamic Signals.And based on original pulse condition oscillogram, the detection suitably compression on time shaft when with each position just obtains pulse amplitude-arteries and veins position (pulse pressure) graph of a relation.Several figures comprehensive down, just from shallow dark, the power of pulse of arteries and veins position, the size of pulse amplitude, the length of arteries and veins body, the variation of arteries and veins shape etc., floating, heavy, empty, real, large and small, long and short, sliding, puckery, the string basic feature of cognitive pulse condition.Also under best pulse pressure, detect 50 above cardiac cycles, obtain the number of rapid pulse, and with synchronous the showing of the Pulse Rate of per minute.In the indagation rapid pulse, and from the variation of arteries and veins rule, promptly pulse beat sometimes fast and sometimes slow, or the time termination is arranged, differentiate in the uneven state learn pulse condition late, number, short, knot, for situation.Especially when tying up to, the pass with pulse wave and pulse amplitude-arteries and veins position (pulse pressure) just can obtain three-dimensional pulse condition topography after computer is integrated.This is comprehensive, and multifaceted pulse condition information is expressed, and the pulse condition overall picture is come into plain view.And then by computer software, carry out time domain, the frequency domain of pulse condition, and during frequency spectrum refinement analyzing and processing, the boundary of be more convenient for the resolution of combination with special pulse condition reached " sick unified " with arteries and veins.Equally, utilize computer software to edit and integrate out serial pulse condition collection of illustrative plates, set up pulse condition spectrum data storehouse.
Advantage of the present invention is very outstanding: be the gentle elasticity touch-pressure sensation feature of height that refers to face with the anthropomorphic dummy who is really true to life that bionic type " artificial skin " pulse image sensor is made, various pulse signals by the pick off taking-up, be converted to digital signal, calculate through computer for analysis, on display screen, single channel or multichannel pulse signal figure and data are shown at random, also can write down out by printer, meter record instrument copy.Can gather the pulse wave that shows in a period of time, be the original objective base of differentiating the pulse condition state; Can obtain pulse amplitude one arteries and veins position (pulse pressure) graph of a relation; Can obtain the sering aspect graph; Can obtain combination and special pulse condition refinement analysis chart; Can draw three-dimensional pulse condition topography, be the dynamic change situation of comprehensively holding pulse condition from space-time, can be observed " position, shape, gesture, number " comprehensive morphological of pulse condition, is the strong objective evidence that comparatively ideal rounded analysis diagnoses the illness.
