Description

Finger-cover type multi-kind pulse wave information measuring method and device

The present invention relates to a kind of medical diagnostic method and used instrument, especially refer to a kind of little sensor that utilizes several to be located at cover portion bottom surface, measure near the multiple pulse wave information at three acupuncture points of human body wrist, and each information is shown on the display, for medical personnel or research worker finger-cover type multi-kind pulse wave information measuring method and device as the auxiliary implement of measuring pulse condition.

The existing traditional Chinese medical science is seen the marrow of examining, and in brief, is " hope, hear, ask, cut ", and is wherein, most important with pulse-taking and inspection of the tongue again.About the pulse-taking ultimate principle, be because the blood of human body is flowed out by the heart pressurization, through the vital organs of the human body, flow to limb end then, flow back to heart at last again, therefore, in case if there is disease to take place in the vital organs of the human body, certainly will influence the equilibrium of whole circulation system, this calls imbalance, and at this moment, pulse condition is different naturally, if the measured pulse wave information in acupoint via the wrist below should reflect the intravital present situation of this patient.

But, because pulse-taking is a kind of very unique diagnostic method in the Chinese medicine, the Chinese physician is with three specific acupoints of finger presses (being cun,guan,chi), according to floating, in, heavy press degree feels pulse condition, with the classification of traditional traditional Chinese medical science, has 28 kinds of pulse conditions, delicate complexity, not only find it difficult to learn, also difficulty refers to measure with three accurately, and a piece of wood serving as a brake to halt a carriage Wei in ancient times once resolved into sensation under eight kinds of fingers with the pulse condition of the traditional Chinese medical science.I.e. " gentle, sliding puckery, the length of the depth, vascular thickness, pulsation power, ripple frequency, the pulsation rhythm and pace of moving things, pulse condition string " eight kinds.Up to the present, with the person's of feeling the pulse experience, not only be not easy measured pulse condition complete documentation is got off mostly, also be unfavorable for the teaching and the research of the traditional Chinese medical science, more different patients' pulse condition difference can't be done accurate lateral comparison.

Opposite, but having some to capture the aid of single signal (SIGNAL) at a certain specified point in the doctor trained in Western medicine can be for utilizing, for example, available sphygomanometer is measured accurate pressure value (systolic pressure and diastolic pressure), and available electrocardiogram is learnt the feature that the single pulse wave of heart changes ...But measured data only limit to single position, and each instrument is only limited to measures single pulse wave signal (maximum or wave form varies), the multiple information and the feature of various pulse conditions can't be grasped comprehensively.Particularly, about the frequency of pulse wave, pulse joint rate, the expansible power of blood vessel, regularity, the warm degree of blood vessel surface, the pulse condition difference of Different Acupoint, the pulse condition difference between the right-hand man or the like, all be difficult to measure with existing doctor trained in Western medicine instrument.In addition, some instrument that is used for measuring pulse wave information in the blood vessel must perversely be worn skin and inserts in the blood vessel in the doctor trained in Western medicine, belongs to the sensor of intrusive mood, and its shortcoming is to cause patient's inconvenience, uneasiness and uncomfortable when measuring easily.

Yet, existing in recent years many domestic and international personages constantly study the instrument of this kind measurement pulse wave, see also Fig. 1, this commonly uses electropulsograph for one of Chinese research, and it comprises that one has overarmformula force transducer 91, anelectropulsograph 92 and anoscillograph 93 of strain-type rigid contact.Because thistransducer 91 directly is sheathed on the wrist, can only measure the single one physical signal (for example Pressure Fluctuation Signal of skin surface) on the single acupuncture point, not only when beginning to locate, proofread and correct and be difficult for, also can't carry out simultaneously with manually feeling the pulse, important disadvantages is to be that it can only obtain the fluctuation signal of the single kind at single acupuncture point.Same, though the transducer that also has many people to be made with other designs can't break away from the Design Mode of commonly using of " single cave point, single signal " eventually.

Therefore, the middle medical circles utmost point waits to develop a kind of non-intrusion type auxiliary measuring instrument of observing the various pulse wave information of patient in a plurality of acupuncture points for the person of feeling the pulse.

In addition,, see also measurement flow chart shown in Figure 8, consist essentially of the following step about finger-cover type multi-kind pulse wave information measuring method of the present invention.

One, sheathed step 11: the person of feeling the pulse is inserted in its certain forefinger, middle finger and nameless end on the other hand respectively with at least three 2A of cover portion, 2B, 2C;

Two, contact procedure 12: contact position, at least three predetermined acupuncture points, be meant especially to be positioned at human body wrist neighbouring chi, pass, very little three acupuncture points;

Three, sensing step 13: the multiple pulse wave information of utilizing above-mentioned each acupuncture point of little sensor 22 measurements of electronic type;

Four, treatment step 14: above-mentioned measured information translation is become 4 information that can read of a display; And

Five, step display 15: the pulse wave information that shows each acupuncture point ondisplay 4.

As for will once selecting three acupuncture points for use, and preferably in the reason at " chi, pass, very little " three acupuncture points, see also Fig. 3, that be because these three acupuncture points in the pulse-taking of the traditional Chinese medical science, it is the known basic acupuncture point of the person of feeling the pulse (need not give unnecessary details its detail location) at this, as long as the patient reaches and can very easyly massage, and, by these three pulse conditions that the acupuncture point is measured, can be with reference to many TCM Document data that are handed down preciousness from ancient times, how analyze, conclude the affiliated pulse condition of this patient again, and then study and judge its disease and weight.

In addition, see also Fig. 7, when the central acupuncture point at " chi, pass, very little " three acupuncture points was pushed with heavier strength by middle finger, theblood vessel 6 in the arm was pressed down and forms the less minor diameter part of adiameter 61, this moment, its blood vessel upstream and downstream form a diameter biggerupstream portion 62 anddownstream portion 63 respectively.Because thisminor diameter part 61 forms a baffle area,, make the blood pressure ofupstream portion 62 slightly to raise and the blood pressure ofdownstream portion 63 can slightly reduce according to hydromechanical principle.Therefore, at these three acupuncture points, can measure respectively three groups of different pulse wave signals, so the person of feeling the pulse can judge pulse condition characteristic and the difference thereof of this patient at these three acupuncture points thus, thus more accurate this patient's of understanding health.

By contrast, measure the mode of " multiple " pulse wave information with three acupuncture points of the traditional Chinese medical science, as if (for example take blood pressure than the single position and the single signal of doctor trained in Western medicine with sphygomanometer, or measure per minute pulsation number with code table) metering system more accurate reliable, if, in the existing pulse-taking mode of the traditional Chinese medical science, do not hindering the person of feeling the pulse to feel the pulse under the prerequisite of process, add aid of the present invention, then do not feel the pulse the person when feeling the pulse, the actual pulse condition with each acupuncture point of patient that can be synchronous is shown on the display, and becoming can be for the waveform of observing and writing down.

The applicant emphasizes that once more the present invention does not really want replacement and manually feels the pulse, but as a kind of auxiliary survey tool, when the person of feeling the pulse feels the pulse, can demonstrate the pulse wave information at measured each acupuncture point synchronously.

Certainly, still there are many examples in the present invention, therebetween the only variation on the details.For example, as shown in Figure 9, be second embodiment of finger-cover type multi-kind pulse wave information measuring device of the present invention, its little sensor 22 is except comprising that four pairs are the gibbosity form hydraulic die cushion 23 (along the flow direction of blood vessel 6) and four pairs of pressure perceptron 24 (not shown), comprise again:

One temperature sensor 25 can be infrared induction, so that measure the temperature signal of the position that is touched;

One displacement perceptron 26 so that measure the displacement signal of the position that is touched, refers in particular to the slight shrinkage mobile status of skin surface;

One voltage perceptron 27 is so that measure the voltage signal of the position that is touched.

Therefore, can record simultaneously each acupuncture point pulse pressure, temperature, displacement, and potential waveform change, have greatly for the teaching of the traditional Chinese medical science and research and benefit.Have eight as for the measured pulse pressure signal in each acupuncture point, then can earlier highest signal in eight signals in thesignal adapter 3 and lowest signal be removed, and after six pulse pressure signal averagings only will being left, pulse pressure signal after demonstrating on average again, in like manner, the present invention also can adopt other signal processing modes of commonly using to eliminate assorted letter, does not give unnecessary details in addition at this.

Certainly, the present invention can comprise a signal recorder 7 (not shown) again again, the shown signal record that goes out can be got off, and this signal recorder 7 can be the disk drive of a printer or a PC.

In addition, the shape ofaforesaid cover portion 2 also can be revised a little, and becomes the form of the fixing band (not shown) of the finger thin film paster (not shown) of a contact finger stricture of vagina face and one or more contact fingernail part, so, also can be inserted in, reach identical purpose for finger.

In sum, advantage of the present invention can be summarized as:

1, not hindering the person of feeling the pulse to see examines;

But the multiple pulse wave signal at 2 each acupuncture point of simultaneous display can comprise pulse pressure, temperature, position Move, reach the required information such as voltage, for seeing the usefulness of examining.
