A kind of traditional Chinese pulse-diagnosis instrument based on low frequency audible sound wave

Technical field

The utility model belongs to TCM pulse diagnosis technical field more particularly to a kind of pulse wave spectrum based on low frequency audible sound wave Instrument.

Background technique

Traditional pulse study is also known as macroscopical pulse study: mostling come from Shanxi for 27 arteries and veins of 24 arteries and veins and Li Shizhen of the Ming Dynasty of Wang Shuhe, examines Refer to cun, guan and chi, three places at the wrist where the pulse is usually taken three pressed in patient with the three of doctor when arteries and veins, three layers of modrate and heavey pressing are divided into the depth felt the pulse；Pass through finger tip sense The pressure feedback being subject to judges the health status of body.But traditional pulse study is mainly used in the yin-yang table for judging disease Cold and heat and asthenia and sthenia is only capable of the generation area of macroscopic view reflection lesion, is not suitable for the disease of the specific organ of diagnosis modern medicine.

It with the development of the times and needs, has been born and has been capable of the microcosmic pulse study of refined diagnosis modern medicine disease.

The pulse characteristics of most diagnostic value in microcosmic pulse study be in the past macroscopical pulse study it is general be considered stagnation of the circulation of vital energy blood The stasis of blood and hurt the few weak thready of essence and blood, but the weak thready of macroscopical pulse study is presented on which branch of cun, guan and chi, three places at the wrist where the pulse is usually taken, which level and time point and does not have Have accurate cun, guan and chi, three places at the wrist where the pulse is usually taken branch, depth layer positioning and fix time a little, therefore the work of precise positioning internal organs organ disease can not be played With.And microcosmic pulse study then finds that puckery fight (can not position which branch of cun, guan and chi, three places at the wrist where the pulse is usually taken, depth layer and fix time with traditional macro pulse study The weak thready of point has significant difference) the different branches of pulse cun, guan and chi, three places at the wrist where the pulse is usually taken, the layering of the different depths and pulse ascent stage can be appeared in With some time point of descending branch, due to can accurately determine cun, guan and chi, three places at the wrist where the pulse is usually taken branch, depthkeeping shallow-layer and fix time a little, it is possible to compare It is accurately judged to the disease of corresponding internal organs organ tissue.Puckery fight of microcosmic pulse study mainly reflects different internal organs organ tissues The feature of the diseases such as various active chronic inflammations and local blood circulation disorder, puckery fight caused by different organs lesion can be specific Pulse layering, cun, guan and chi, three places at the wrist where the pulse is usually taken branch and pulse beating ascent stage or descending branch occur；As hepatitis can be in radial artery The pass portion in deep layer face and pulsation descending branch touch it is puckery fight, various ephritis can ruler portion in radial artery deep layer face and pulsation decline Section touch it is puckery fight, gastritis then can in radial artery the pass portion of level and pulsation descending branch touch puckery fight.

Utility model people is in long-term clinical practice, by the cun, guan and chi, three places at the wrist where the pulse is usually taken difference branch and the difference that often touch radial artery Pathological character in depth level is puckery to fight, it is found that the vibration frequency of the Adam's apple of the puckery feeling fought under finger and sounding extremely connects Closely, therefore think that the main physical characteristics of puckery generation of fighting may be the sound wave of different frequency.

The study found that the blood flow in human body in 90% or more artery is laminar condition, laminar flow center blood flow velocity is close fastly Degree is high, and the laminar flow at vascular wall is due to low compared with the slow density of die flow velocity with the frictional force of tube wall.

When human heart is shunk, the vascular wall that blood strikes the organ of generation lesion can generate the sound wave letter of different frequency Number；The laminar flow of different levels has the conduction of the sound wave of different frequencies due to the difference of density the possibility of enhancing and decaying.

Therefore, the vibration acoustic (audible sound wave) detected in radial artery different layers current density can achieve to part doctor trained in Western medicine disease Disease carries out the purpose of relatively fining judgement, and research and tentative diagnosis disease for microcosmic pulse study have very important significance.

Retrieval discovery:

What is be most widely used in pulse wave spectrum detection field is the pulse manifestation testing system based on piezoresistance sensor, main logical Over-voltage force snesor measures human pulse signal, and pulse signal obtains human body pulse chart after the signal processings such as amplification filtering. Common pressure sensor has metal strain formula, semiconductor strain chip and fiber grating pulse diagnosis sensor；The sensor is equal Belong to direct contact type pressure sensor, can realize that the layering of Traditional Chinese Medicine is felt the pulse；But the pressure by detecting pulse Method for pulse reflect macroscopic view hemodynamic have biggish value, be suitable for traditional pulse study, but can not detect Puckery in microcosmic pulse study fights, therefore is not used to the disease of the specific organ of detection modern medicine.

Prior art discloses acquisition infrasound information, to obtain the technical solution of certain pulse condition information, using staying Electret microphone carries out infrasonic acquisition；But due to using contactless coupler, therefore it can not realize layering Acquisition；Therefore it in the rear end of electret microphone also needs that pressure sensor is arranged, to obtain the pulse signal under different pressures； Also, experiments have shown that conduction of the infrasound in the different static liquid of density and the blood of flowing is very poor, cause information loss It is more, therefore puckery information of fighting can not be accurately extracted by detecting infrasonic sound.

Blood vessel doppler technique disclosed in the prior art only can detecte length and width, the arteries and veins flow velocity degree of pulse, right It is not acted on then in the pressure and vibration wave of pulse.

To sum up, the technology of the pressure information or infrasound information that acquire pulse is appropriate only for traditional pulse study, can not detect The disease of the puckery specific organ fought, be not used to refine detection modern medicine in microcosmic pulse study out.In the prior art not There is the open audible information of acoustic wave extracted in pulse to carry out the technology of the refined diagnosis of the specific organ disease of modern medicine, does not also have There is corresponding diagnosis by feeling the pulse instrument to come out.

Processor includes audio processing software, extracts analysis to collected audible sound wave；It is selected in the present embodiment The extraction and analysis of COOL EDIT PRO software progress acoustic signals.

It should be noted that computer and audio processing software used in the utility model are all existing technology energy It enough realizes, without carrying out the improvement of program.

In order to verify the feasibility of this experimental provision, carry out being verified as follows respectively:

Experiment 1: static liquid is divided into 3 layers, first layer to the close of third layer by the static liquid of production different densities gradient Degree gradient is increased with this, represents different density gradients；The sound wave of detection different frequency passes in different densities liquid medium Lead difference.

Experiment 2: existed using anticoagulant pig blood simulation arterial circulation state observation sound wave of different frequency in different laminar flows Variation is conducted in different laminar flows.

Experiment 3: to Chinese Experimental Miniature Pig, hepatitis model is manufactured with carbon tetrachloride, is inspection with axillary artery and femoral artery The puckery window fought is surveyed, the conduction variation of puckery fight class sound wave of the modeling front and back in specific laminar flow is compared.

By experiment 1 and experiment 2, we are obtained:

The conduction decaying of infrasound frequency band sound wave in the static liquid medium of different densities gradient less than 20HZ is bright It is aobvious, and the conduction of sound wave in the static liquid medium of different densities gradient of the low frequency section (20HZ-300HZ) of audible sound wave declines Subtracting unobvious or even some frequencies has the case where enhancing.

The conduction decaying of sound wave is obvious in infrasound frequency band less than 20HZ pig blood anticoagulant under simulation loop state, And the conduction decaying of sound wave is not in low frequency section (20HZ-300HZ) pig blood anticoagulant under simulation loop state of audible sound wave It is obvious even to have the case where enhancing.

The infrasound of 15HZ and the audible sound wave of 20HZ frequency is set forth in third layer density level bands in Fig. 3 (a)-Fig. 3 (b) The conduction waveform diagram in static liquid under degree；As can be seen that static liquid of the infrasound of 15HZ in third layer density gradient Conduction decaying in medium is obvious, and the audible sound wave of 20HZ, the conduction in the static liquid medium of third layer density gradient Basically no attenuation.

The sound wave that Fig. 4 gives different frequency conducts to summarize in three kinds of density gradient static liquids compares figure, and Fig. 5 is provided The conduction of the sound wave of different frequency summarizes and compares figure in anticoagulant pig blood under simulation loop state；

As can be seen that the amplitude of signal transduction is clearly in the audible sound wave low-frequency range of 20HZ-300HZ；And it is greater than The amplitude conducted in the sound wave frequency range of 300HZ pig blood anticoagulant in three kinds of density gradient static liquids and under simulation loop state It is very faint, close to zero.

Therefore, the conduction attenuation degree compared to infrasound in the different static liquid of density and the blood of flowing is high, It is easy to cause the loss of information and the puckery information of fighting in microcosmic pulse study can not be accurately extracted；The low frequency section of audible sound wave (20HZ-300HZ) will not lose information in conductive process substantially, can accurately extract puckery information of fighting.

By experiment 3 we obtain: at the axillary artery and femoral artery of carbon tetrachloride hepatitis Mini-pig model it is puckery put out it is existing Abnormal sound wave is the low frequency section of audible sound wave.

Collected Mini-pig model deep layer pulse beating audio signal before and after modeling is set forth in Fig. 6 (a)-Fig. 6 (b) Waveform diagram, from comparison diagram as can be seen that due to being superimposed the audio of breath sound in arteriopalmus sound collecting before modeling Interference, acoustic wave form figure has mixed the sound wave of breath sound, but it is also possible to significantly find out the descending branch ratio in the audiograph of pulse It is smoother to occur without jagged audible sound wave.And collected Mini-pig model deep layer pulse beating audio signal after modeling In, there is apparent sawtooth wave in the descending branch of the audiograph of acquisition, i.e. the puckery of heard sound wave mode fights.

Finally, acquire respectively the middle layer in 30 Patients with Chronic Gastritis radial artery passes portion pressure waveform and acoustic waveform into The pressure wave under collected same position (pass portion), same level (middle layer) is set forth in row comparison, Fig. 7 (a)-Fig. 7 (c) Shape and acoustic waveform, Fig. 7 (b) give the acoustic waveform under the collected same position of normal person, same level；Comparison hair It is existing, in the pressure waveform of same position (pass portion) and the gastritis sufferer of identical level (middle layer) acquisition and normal person without gastritis Pressure waveform does not have difference, can not detect that the puckery of exception in microcosmic pulse study fights in the collected pressure wave of gastritis sufferer, Therefore pressure wave is not used to the disease of the specific organ of detection modern medicine.In the collected same position of normal person, same layer Do not detect that the puckery of audible acoustic wave type fights in audible acoustic waveform under secondary yet；But in the collected sound wave of gastritis sufferer, The puckery of audible acoustic wave type that can be accurately extracted in microcosmic pulse study fights, and sees the zig-zag in Fig. 7 (c) in circle, therefore pulse The acquisition of audible sound wave have very important significance for detecting the disease of specific organ of modern medicine.

To sum up, the traditional Chinese pulse-diagnosis instrument disclosed by the utility model based on low frequency audible sound wave, compared to traditional acquisition pressure The diagnosis by feeling the pulse instrument of Reeb information and infrasound information can more accurately detect the puckery information of fighting in microcosmic pulse study, and then basis The disease of the specific organ of the information auxiliary judgment modern medicine detected, realizes and the fining of modern medicine disease is examined It is disconnected, greatly improve the accuracy rate of feeling the pulse of microcosmic pulse study.

It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this The limitation of type protection scope, those skilled in the art should understand that, based on the technical solution of the present invention, ability Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model Within enclosing.
