Description
Technical field
The present invention relates to pulse wave spectrum technical field of automation, and in particular to a kind of pulse condition five based on laser three-dimensional scanning
Tie up the device and method of automatic acquisition of scientific information.
Background technology
Chinese medicine pulse includes abundant biological information, is the important content of the Chinese medicine four methods of diagnosis.Pulsation should refer to the image of (finger)
Referred to as pulse condition refers to the image and dynamic of pulse.The formation of pulse condition and internal organs qi and blood are closely related.Shanxi uncle Wang and《Pulse classic》By arteries and veins
As being summarized as 24 kinds；Bright Li Shizhen (1518-1593 A.D.)《It is on the point of lake pulse study》It is set to 27 arteries and veins；Ming Lishi materials《House is examined to look straight》Increase again into
Swift pulse closes 28 kinds of pulse conditions.Later age continues to use twenty-eight kinds of pulse condition more.
Pulse condition element refers to four aspects such as element of pulse condition, including position, number, shape, gesture.Artificial pulse condition
Identification relies primarily on the feeling of finger.There are many type of pulse condition, and four TCM Document Chang Congwei, number, shape, gesture aspects are analyzed
Conclude, its frequency with pulse, the rhythm and pace of moving things, the position of presentation, length, width, the fullness degree of vascular, tensity, blood flow it is unobstructed
Fluency, the factors such as power of heartbeat are related.Pulse condition element is grasped, for understanding the feature of various pulse conditions and forming machine
Reason, can play hold letter drive numerous effect.
One arteries and veins position：Refer to the position and length that beat pulse shows.Every time feel the pulse should all examine pulse show position the depth,
Length.The position of normal pulse is not floating not to sink, in take and can obtain, cun,guan,chi three has arteries and veins.If table shallow person in arteries and veins position is surface pulse which can be felt when touched only lightly；Arteries and veins position
Deep person is eddp pulse etc.；Pulse is more than that three persons of cun,guan,chi are long pulse, and it is short arteries and veins to pulse not as good as very little, ruler person.
Two rapid pulses：Refer to extremely number and the rhythm and pace of moving things of beat pulse.It feels the pulse the frequency speed that should all examine pulse every time and the rhythm and pace of moving things is
It is no uniform.The frequency of normal adult, pulse are about 70-90 times per minute, and the rhythm and pace of moving things is uniform, are not had a rest only.As respiration five to
Upper is rapid pulse etc.；The most retarded pulse of respiration discontented four；Appearance is had a rest only, there is the difference of the arteries and veins such as abrupt pulse, nodus, slow；Arteries and veins restrains speed
Irregular person is 35 uncomfortable, there is scattered arteries and veins, weak thready etc..
Three arteries and veins shapes：Refer to the forms such as the width of beat pulse.The shapes such as the size of pulse, soft or hard should all be examined by feeling the pulse every time.
Arteries and veins shape is mainly related with the factors such as the amplitude of the fullness degree of vascular, pulse wave.If vascular is relatively full, pulse magnitude the greater is
Full pulse；Vascular fullness degree is smaller, and pulsatile range smaller is thready pulse；Vascular poor flexibility owes soft person as taut pulse；Arteries and veins body softness nothing
Power person is soft pulse, slow arteries and veins etc..
Four arteries and veins gesture：Refer to the trend such as power, the smoothness that pulse should refer to.Arteries and veins gesture includes many factors, such as pulsation axial direction and
Radial dynamics；Mainly there is the fluency caused by heart and drag effects；It is influenced by blood vessel elasticity and tension and is generated tight
Tonicity etc..The strong and weak and smooth degree of pulsation force should all be examined by feeling the pulse every time.Normal pulse, should refer to gentle, and dynamics is moderate.It answers
Refer to is effectively forceful pulse；It is feeble pulse that should refer to powerless；Unobstructed state is preferable, and it is smooth pulse that arteries and veins, which carrys out fluent round and smooth person,；Unobstructed state is poor, arteries and veins
It is weak thready etc. to carry out involved and abstruse impassable patient.
It is to constitute the fundamental of pulse condition, and observe and learn the bare bones of pulse condition by experience above.The discrimination of pulse condition, Main Basiss doctor
Feel under the finger of person, therefore, doctor Cha Mai, it is necessary to repeat finger sense, carefulness observe and learn by experience, by various pulse condition elements integrate into
Row analysis, could form than more complete pulse condition, could correctly differentiate various abnormal pulse.
What diagnosis by feeling the pulse relied on is the feeling function of mankind's finger tip.Human skin can perceive a variety of senses such as tactile, the pain sensation, heat feel
Feel, the perception of wherein tactile is particularly important.The tactile of people is mainly by being distributed in a large amount of mechanical stimulus senses of skin different depth
4 kinds of thigmoreceptors perception in receiver：The corpuscula lamellosa of Meissner's corpuscle and deep skin in superficial skin is quick
Adapt to receptor, the former can 3 ~ 40Hz low frequency narrow dynamic ranges of quick response environmental stimuli, realize low-frequency vibration and movement examine
It surveys and the sensory functions such as grip control；The latter can 40 ~ 500+Hz high frequency wide dynamic ranges of quick response environmental stimuli, realize
High-frequency vibration and tool such as use at the sensory functions.A kind of tool on the other side to be, being distributed between whole body epidermal basal cell
The Ruffini's corpuscle of the merkel's cells of short digitation and spindle shape positioned at intradermal is slowly adapting receptor, Qian Zheke
The geometric distortion of 0.4 ~ 3.0Hz low frequency narrow dynamic ranges of slow-response, lasting pressure, even the extraneous thorn such as curved surface, edge wedge angle
Swash, the sensory functions such as implementation pattern/Morphology observation and texture perception；The latter can 100 ~ 500+Hz high frequency dynamic ranges of slow-response
Wide continues downward pressure, the lateral environmental stimulis such as skin stretch and skin glide, realizes finger position, stablizes crawl, cuts
To the sensory functions such as power and the direction of motion.The characteristics of according to tactilely-perceptible, can be divided into tactile sliding tactile and softness haptic perception
Two kinds.Sliding tactile is parallel to the perception of finger contact surface, main geometry, texture, the temperature etc. for reflecting body surface；
Softness haptic perception is perpendicular to the dynamic sensing in finger contact surface direction, the main flexibility or rigidity for reflecting object.Partes corporis humani position
Thigmoreceptor distribution density difference is big.The finger tip and the centre of the palm of adult distributed 241 and 58cm respectively2Thigmoreceptor,
So that the spatial resolution significant difference of partes corporis humani position, the spatial resolution of finger tip, depth perception 0.2mm, point-to-point transmission are
The critical thoughts and feelings response time of 0.5mm, two events of different location are 50ms grades of 30 ~.Controllable pressure-sensitivity research table
It is bright：The normal pressure threshold value of male's palm and finger tip averagely respectively may be about 0.158g and 0.055g, and the analog value of women is respectively
0.032g and 0.019g.

It is inside and outside to make much progress in terms of developing traditional Chinese medicine pulse electro pulsograph, especially the mid-1970s, the ground such as domestic Tianjin, Shanghai, Guizhou, Jiangxi
Study of pulse condition cooperative groups interdisciplinary are set up in succession, multidisciplinary cooperate promotes Chinese medicine pulse research work to enter one
New boundary.
There are many pulse condition detection sensor style, have single portion, three, single-point, multiple spot, rigid contact formula, soft contact formula, gas
The compositions such as pressure type, silicon cup formula, liquid mercury, liquid water, primary-secondary type.The major components of pulse condition probe have foil gauge, piezo-electric crystal, list
Crystal silicon, light-sensitive element, PVDF piezoelectric membranes etc., wherein with single portion's single-point strain chip be most extensively, but in recent years to
Three multipoint mode directions are developed.But have now been developed that the pulse transducer come can only all acquire pulse pressure beating both at home and abroad at present
The information of aspect cannot characterize other multidimensional information.
Objective pulse examination shows arterial pulse in addition to the information for sending out pressure pulsation, also tube chamber volume, blood flow
Speed, the various information such as three-dimensional motion of vascular, i.e. four aspects such as the position of pulse condition, number, shape, gesture.Only with pressure sensor etc.
The pressure arteries and veins figure that traditional sensors are acquired is difficult to the index of all quantitative reflection pulse condition inscape, and (some passes through multiple spot pressure
Force information is converted to 3-D view, but due to collection point deficiency, pressure information accuracy problem, and three-dimensional reconstruction is inaccurate).
Therefore, on the basis of existing pulse condition automatically analyzes achievement in research, acquiring three-dimensional images technology, artificial intelligence skill are made full use of
Art, automated control technology realize the pulse conditions holography synchronous acquisitions such as pulse condition information pressure, Three-Dimensional Dynamic, to realize Traditional Chinese medicinal wrist
