As shown in Figure 1, this utility model Chinese medicine pulse checkout gear comprises Chinese medicine pulse transducer group ［ 1 ］, Chinese medicine pulse signal processing unit ［ 2 ］ and Chinese medicine pulse show and ［ 3 ］ three parts of record cell, wherein the Chinese medicine pulse transducer group as shown in Figure 2, it comprises CUN transducer ［ 4 ］, GUAN spot transducer ［ 5 ］ and chi portion transducer ［ 6 ］, they are installed in three support arms ［ 7a ］ that transducer is regulated controlling organization ［ 7 ］ respectively, ［ 7b ］, on ［ 7c ］, transducer is regulated controlling organization ［ 7 ］ and is guaranteed very little, close, three transducers of chi ［ 4 ］, ［ 5 ］, ［ 6 ］ can be at three-dimensional space motion, at x, the y direction of principal axis moves very little, close, three transducers of chi, can make their contact correctly be pressed in respectively the patient scratch tremulous pulse cun, close, on three positions of chi, move transducer in Z-direction, can regulate the size of feeling the pulse pressure.
Very little in the present embodiment, close, three transducers of chi adopt hyperbola contact cantilever beam strain-type structure, except GUAN spot transducer ［ 5 ］ adopts composite structure, CUN transducer ［ 4 ］ and chi portion transducer ［ 6 ］ structure are identical, their profile as shown in Figure 3, it comprises that detection faces is tetragon, wherein opposed two limits are parallel, opposed in addition two limits are the contact ［ 8 ］ of hyperbola, transducer housing ［ 9 ］ and transducer gland ［ 10 ］, the effect of gland ［ 10 ］, the one, closed transducer is also pushed down the cable ［ 11 ］ of being drawn by transducer housing ［ 9 ］ inside, and the 2nd, nationality is regulated on the support arm (dotting among the figure) of controlling organization ［ 7 ］ transducer is installed in transducer.
Fig. 4 is the profile of the CUN of Fig. 3 and chi portion transducer ［ 4 ］, ［ 6 ］, has shown its internal structure.It comprises the cantilever beam ［ 12 ］ as the part of sensing mechanism made with the metallic elastic material, in order to the briquetting ［ 13 ］ of cantilever mounted beam and be attached near cantilever beam ［ 12 ］ stiff end for example strain resistor of the sensing element ［ 14 ］ on the upper and lower faces.If make sensing element, can only stick on the face of cantilever beam ［ 12 ］ with the full-bridge type strain resistor.Contact ［ 8 ］ is positioned at the free end of cantilever beam ［ 12 ］, and cantilever beam ［ 12 ］ and contact ［ 8 ］ constitute the sensing mechanism of transducer.Be that transducer body comprises sensing mechanism, sensing element and housing ［ 9 ］, gland ［ 10 ］ and cable ［ 11 ］.
Fig. 5 is the fundamental diagram of hyperbola contact cantilever beam transducer, Fig. 6 is the vertical view of Fig. 5, and establishing among the figure and scratching arteries ［ 15 ］ direction is y, and diameter is D, the wrist surface is in x, y plane, the contact of hyperbola ［ 8 ］ contour curve functional expression ± f(x) expression.Point ［ 16 ］ is the center of pasting sensing element ［ 14 ］, and the distance that it leaves contact ［ 8 ］ far-end is L, when satisfying condition:
F(x)=C/L-x c=constant
At this moment, the strain on the point ［ 16 ］
ε=(12c)/(Ebh
2) AD ∝ A
In the formula, E, b and h are respectively the elastic modelling quantity of cantilever beam ［ 12 ］, width and thickness, A scratches the pressure that arteries ［ 15 ］ promotes contact ［ 8 ］, prove thus, when contact ［ 8 ］ when shape is hyperbola, the locational strain of the last subsides of cantilever beam ［ 12 ］ sensing element and contact ［ 8 ］ cover the position of scratching arteries ［ 15 ］, and it doesn't matter, when the actual detected pulse condition, reasons such as motion just because of inevitable operate miss of operator and measured, making contact cover the position of scratching tremulous pulse can not immobilize, thereby when adopting other shape contacts, the repeatability of testing result is very poor, and the hyperbola contact transducer excellent operation repeatability when having guaranteed to detect pulse condition information, thereby reduced the requirement of the operating technology that Chinese medicine pulse is detected significantly, improved the repeatability in the human body actual detected, long-time stability and detection by quantitative precision.
In commercial transducer designs, available proximate trapezoidal contact replaces the hyperbola contact, at this moment, to the linear relationship of ε and A, only causes to be not more than 2% error.This allows in Chinese medicine pulse detects, and favourable part is that the processing technique of contact is simplified greatly.
Sensing element in the transducer ［ 14 ］ is connected with Chinese medicine pulse signal processing unit ［ 2 ］ by cable ［ 11 ］, the pulse condition pressure information is become the signal of telecommunication with the power that is applied to patient's wrist to be handled, in the pulse signal that CUN transducer ［ 4 ］ and chi portion transducer ［ 6 ］ are sent, feeling the pulse pressure direct-flow signal and pulse wave alternation fluctuating signal mix.
GUAN spot transducer ［ 5 ］ is except comprising and very little, chi portion transducer ［ 4 ］, ［ 6 ］ identical structure division in the present embodiment, be outside the above-mentioned transducer body, comprise that also the accessory sering form that is compounded on its contact ［ 8 ］ detects linear array type assisting energy transducer, it and transducer body are formed combined type Chinese medicine pulse transducer, as shown in Figure 7.This sering form detects linear array type assisting energy transducer and is made up of a plurality of array element transducers, each array element transducer comprises a microsensor and a micro sensing mechanism, wherein, there is a detection faces ［ 18 ］ that detects the sering form in each micro sensing mechanism, they are arranged on the axis of symmetry of combined type transducer contact ［ 8 ' ］ detection faces ［ 17 ］ equally spacedly, constitute the part detection faces of combined type transducer contact ［ 8 ' ］.Fig. 8 a-8c shows shape and the arranging situation that trapezoid combined type transducer contact ［ 8 ' ］ detection faces ［ 17 ］ commonly used goes up sering form detection faces ［ 18 ］, Fig. 8 a wherein, 8b, 8c represents trapezoidal respectively, the situation of the arrangement of the sering form detection faces ［ 18 ］ of rectangle and circle, in these three kinds of designs, thereby the number of array element transducer sering form detection faces ［ 18 ］ is generally all got 6 to 9, be arranged in parallel, adjacent two sering form detection faces ［ 18 ］ center distance are all 0.6 to 1.1 millimeter scope, and the required precision of pulse wave spectrum is considered in the selection of these parameters.When composite transducer contact ［ 8 ' ］ is pressed on patient's wrist GUAN spot when detecting pulse condition, some just in time is pressed in and scratches arteries top in these 6 to 9 sering form detection faces ［ 18 ］, array element transducer corresponding to them just has pulse wave signal output, and aligning is scratched the amplitude maximum of a transducer output signal at arteries ［ 15 ］ center, the signal away from the array element transducer output of scratching the arteries center is just more little, just can know sering size and form roughly by inference according to the size distribution of each array element transducer output signal.Accompanying drawing 9a, 9b, 9c show the distribution situation of the pulse wave amplitude of scratching pairing each the array element transducer output of arteries of several different conditions respectively.
The structure of compound a plurality of array element transducers on hyperbola contact or trapezoidal contact, not only select, and many feasible programs are arranged in form in the microsensor and the micro sensing mechanism structure of array element transducer at the number of array element transducer and the shape and size of its sering form detection faces ［ 18 ］.
Figure 10 shows a kind of with the structure of PVDF piezoelectric membrane as the combined type transducer contact of the microsensor of the array element transducer of forming auxiliary transducer, it comprises ladder-shaped frame cover plate made of insulating material ［ 19 ］, the contact skeleton, be embedded in the outer PVDF linear array thin film ［ 20 ］ of the micro sensing mechanism contact skeleton of making by elasticity padding thing that constitutes sering form detection faces ［ 18 ］ in the contact slotted eye and combined type transducer contact detection faces ［ 17 ］ with two edges ［ 20 ' ］ of thin film with ［ 20 " ］ are separately fixed at conductive rubber strip ［ 21 ］ and ［ 21 ' ］ in the arc translot on the opposed identical side of two on contact skeleton.Wherein, contact conducting strip ［ 23 ］ insulating thin ［ 24 ］ identical with n+1 sheet thickness of drawing lead ［ 22 ］ that weld separately that the contact skeleton is done by the identical conductive material of n sheet thickness is spaced and glues together and form, the number of contact conducting strip ［ 23 ］ equals array element transducer number, generally get 6 to 9, in this routine Figure 10, get 7, their shape is all similar to the shape that is clipped in insulating thin ［ 24 ］ therebetween, and its big or small ordering gradual change.Its shape as shown in figure 11, it is opened a rectangular opening ［ 25 ］, lower edge mouth middle part and opens a wedged hole ［ 26 ］, two middle side parts and respectively open an arc-shaped slot ［ 27 ］ and ［ 27 ' ］ and make at rectangular tab upper mouth middle part, but two insulating thins of first and last are not then opened rectangular opening.After the gummed, in arranging the groove that forms, a plurality of wedged holes ［ 26 ］ set the elasticity padding thing ［ 28 ］ of the suitable wedge shape of the equal hardness of 7 thickness, for example silicone rubber etc. constitutes micro sensing mechanism, and its surface is the part that the sering form detection faces ［ 18 ］ of array element transducer constitutes composite transducer contact detection faces.
Figure 12 is the expanded view of the PVDF linear array thin film ［ 20 ］ among Figure 10, be coated with 7 electrodes ［ 29 ］ on its inner surface, be coated with the ground electrode of monoblock on its outer surface, after it being wrapped on the contact skeleton, 7 electrodes contact conducting strip ［ 23 ］ respectively and contact with 7, therefore PVDF piezoelectric membrane ［ 20 ］ can be gone up the electric charge that produces and derive.
Set elasticity padding thing ［ 28 ］ and superscribe the contact skeleton of PVDF thin film ［ 20 ］ and cover plate ［ 19 ］ lower surface gummed, again the upper surface of cover plate ［ 19 ］ cantilever beam ［ 12 ' ］ with the GUAN spot transducer body is glued together.Like this, the assembly that is assembled together by cover plate ［ 19 ］, contact skeleton, elasticity padding thing ［ 28 ］ and PVDF linear array thin film ［ 20 ］ shown in Figure 10 promptly is that one 7 array element piezoelectric type sering form detects auxiliary transducer, is again the contact of combined type Chinese medicine pulse transducer.Be pressed in this contact and scratch arteries ［ 15 ］ when go up detecting pulse condition, the pressure oscillation effect that the sering form detection faces ［ 18 ］ that is covered with blood vessel ［ 15 ］ is subjected to blood vessel ［ 15 ］ will produce flexural deformation, be subjected to pressure at right angle and tension force effect simultaneously, thereby the generation signal of telecommunication, elasticity padding thing ［ 28 ］ provides condition for the flexural deformation of thin film, yet its suitable hardness is also closed the pulse power of beating is delivered on the cantilever beam of composite transducer body.So the performance of the transducer body of GUAN spot transducer ［ 5 ］ is still identical with very little, chi portion transducer ［ 4 ］, ［ 6 ］.
In the design of GUAN spot transducer, keep hyperbola identical or trapezoidal contact cantilever beam transducer as the GUAN spot transducer body with very little, chi portion transducer ［ 4 ］, ［ 6 ］ structure, can detect the average pulse pressure that Chinese physician's finger tip is felt, can resemble the objective value of the best feeling the pulse pressure that finds each patient the Chinese physician and best feeling the pulse pressure and its pairing pulse condition waveform (comprising amplitude) all has good operation repeatability.
Figure 13 represents that with the example of miniature strain resistor as the combined type transducer contact of the microsensor of the array element transducer of auxiliary transducer Figure 14 is the parts and the assembling sketch map thereof of this contact, and Figure 15 is the vertical view of Figure 13.Shown in the figure is the trapezoidal combined type contact of 7 array element transducers, and array element transducer number is generally got 6 to 9.Trapezoidal combined type contact is made of two parts ［ 29 ］ and ［ 29 ' ］, each part is held level with both hands n/2 or n-1/2 and n+1/2 the pectination arrangement of being respectively perpendicular to this sidewall of stretching out by wedge ［ 30 ］ or ［ 30 ' ］ and its long right-angle side place sidewall one, micro metal resilient wedge ［ 31 ］ and ［ 31 ' ］ as the sensing mechanism of assisting transducing constitute, wherein n is an array element number, get in this example under the situation of 7 array elements, the number of micro metal spring beam ［ 31 ］ and ［ 31 ' ］ just is respectively 3 and 4, post the miniature strain resistor of a slice ［ 32 ］ or ［ 32 ' ］ on each micro metal spring beam as microsensor, wedge ［ 30 ］ and 3 micro metal spring beams ［ 31 ］ and wedge ［ 30 ' ］ and 4 micro metal spring beams ［ 31 ' ］ form with the metallic elastic materials processing of monoblock respectively, make two groups of micro metal spring beams ［ 31 ］ and ［ 31 ' ］ cross arrangement mutually, as shown in figure 16, and respectively and reinforcement baffle plate ［ 67 ］ and ［ 67 ' ］ bonding or welding of using the material same to make with it in the both sides that are parallel to each other of wedge ［ 30 ］ and ［ 30 ' ］, make it to be assembled into one, promptly become the combined type contact.14 lead-in wires of 7 strain resistors all can be by being attached to the printed panel switching on the mutual opposed medial wall in two wedges ［ 30 ］ and ［ 30 ' ］, and because of 7 strain resistors can have a common port, historical facts or anecdotes border lead-out wire is 8.Combined type contact so is assembled together with cantilever beam bonding or welding procedure and transducer body, just the GUAN spot transducer of forming combined type, when detecting pulse condition information with it, because the rigidity of micro metal spring beam ［ 31 ］ and ［ 31 ' ］ is bigger, be out of shape less, so for transducer body, original performance of trapezoidal contact transducer remains unchanged, a plurality of array element transducers of being made up of a plurality of micro metal spring beams ［ 31 ］ and ［ 31 ' ］ and a plurality of miniature strain resistor ［ 32 ］ and ［ 32 ' ］ have constituted the sering form and have detected linear array type assisting energy transducer, can detect the size and the form of sering with it.
The another kind of variation of the structure of Figure 13 is, uses miniature strain resistor ［ 32 ］ and ［ 32 ' ］ instead two PVDF piezoelectric membranes respectively, and they are shown in Figure 16 a and 16b, and Figure 17 a and 17b are respectively the dorsal view of 16a and 16b.The pectination thin film is formed by a rectangle part and from the comb-tooth-like portion of flat 3 and 4 the mutual cross arrangements of stretching out of one long side respectively in two PVDF piezoelectric membranes ［ 33 ］ and ［ 33 ' ］, their front, between the rectangle part of each comb-tooth-like portion and vicinity thereof, respectively scribble an electrode ［ 34 ］ or ［ 34 ' ］, at their back side, between the rectangle part of each comb-tooth-like portion and vicinity thereof, scribble ground electrode ［ 35 ］ or ［ 35 ' ］, and each electrode links to each other at rectangle part.Then, shown in this contact component and assembling sketch map of Figure 18, the comb-tooth-like portion of thin film ［ 33 ］ and ［ 33 ' ］ is folded into rectangle part meets at right angles, being coated with conducting resinl at the rectangle part back side bonds together it respectively with the long right-angle side place sidewall of wedge ［ 30 ］ and ［ 30 ' ］, and making each electrode and corresponding micro metal spring beam ［ 31 ］ or ［ 31 ' ］ contact, all electrode outlet lines are also used conductive adhesive.In this embodiment, when the assembling contact, the elastomeric material of cavities filling within it ［ 36 ］, make PVDF thin film ［ 33 ］ good with micro metal spring beam ［ 31 ］ respectively with contacting of ［ 31 ' ］ with ［ 33 ' ］, and can push down lead-out wire, do not influence the motion of micro metal spring beam ［ 31 ］ and ［ 31 ' ］ simultaneously again.
In addition, also available conductive rubber of the miniature strain resistor as microsensor in Figure 13 or piezoelectric ceramics material replace.
