Description
Technical field
This utility model relates to a kind of three probe machinerys that are applicable to traditional Chinese medical science pulse detection, belongs to the technical field of pulse-taking instrument.
Background technology
Pulse-taking is the characteristic diagnostic method of Chinese medicine, has simple, practicality, noinvasive, feature cheaply.Pulse condition has carried Whole Body, comprehensive physiological and pathological information, is to spy on the window that function changes.But its subjectivity, abstract " the heart easy, refer to that lower difficulty is bright " feature also become the significant challenge that pulse wave spectrum modern study faces, therefore the objectifying of pulse-taking, standardized study are extremely important.
The development of pulse-taking instrument becomes with application that pulse wave spectrum objectifies undoubtedly, the main method of standardized study and means, use the ways and means of modern detecting, by the physical features digitized of information of pulse examination and visual and describe objectively and record, rely on computer technology to carry out to obtained information of pulse examination identification and the analysis that quantitative and qualitative analysis combines.
As far back as the 1950's, just there is the scholar of a lot of doctors and related fields in China based on Sphygmology, by for clinical diagnosis and experimentation, has carried out mapping and the analysis of a large amount of common arteries and veins figure, for certain basis has been established in the research that objectifies of pulse-taking.By the analysis for arteries and veins figure, it is found that arteries and veins figure is very sensitive physiologic information, all ages and classes group has the standard of different judgement healths, and the physiological condition of natural environment and human body all has direct impact for arteries and veins figure.And pulse-taking instrument just need to gather and generate arteries and veins figure information for people's pulse condition information, carry out analyzing and processing for user, formulation standard, so that later as the foundation that judges health.
Till now, the relevant scholar of every field has developed the different pulse-taking instrument of diversified performance, and they differ from one another, but due to all limitation, fails to be widely used in clinical use always, and only rest in scientific research and teaching aspect.
Existing pulse-taking instrument mainly, by simulation pulse wave spectrum process, based on the cunkou pulse diagnostic method, by adopting different sensors to carry out signals collecting, then is analyzed pulse condition.Existing pulse-taking instrument mainly contains following a few class choosing of sensor:
1, pressure-type sensor
The pressure-type pulse-taking instrument development time early, is studied and improves through long-time, has also obtained larger development at present.The sensor of pressure-type pulse-taking instrument is mainly divided into three kinds of piezoelectric transducer, piezoresistive transducer and piezomagnetic sensors, and wherein piezoelectric type is the most practical and ripe.Change because beat pulse produces pressure, piezoelectric transducer utilizes the characteristic of piezoelectric, and this pressure signal is converted into the signal of telecommunication, realizes collection and the processing of pulse signal.
2, electro-optical pickoff
Electro-optical pickoff is noncontacting proximity sensor.Due to heartbeat, can cause the variation of blood volume in blood vessel, now, in the time that illuminating ray irradiates, the light of transmission also can change with the variation of blood volume, and the photoelectric sensor that receives transillumination can be experienced this variation, and its dress is changed to the signal of telecommunication, for analyzing use.Photoelectric sensor sensibility is high, and capacity of resisting disturbance is strong, but its blood flow parameter that can record can't satisfy the demands.
3, sonic sensor
Sonic sensor is to catch the essence of pulse signal to design.Pulse condition itself is by generation of vibration, and therefore sonic sensor can obtain the acoustical signal of pulse generation of vibration, and it is carried out to analyzing and processing.
4, ultrasonic Doppler technique
Utilize ultrasonic Doppler technique, can observe the diameter of the thickness of the motion conditions of vascular, blood vessel wall, blood vessel etc., can reflect comparatively intuitively the situation of blood vessel, for analyzing.But this technology be not also very ripe aspect research pulse condition information at present, and cost is comparatively expensive.
In the piezoelectric sensing type pulse-taking instrument being most widely used, according to the difference of pulse-taking instrument sensor probe form, mainly pulse-taking instrument can be divided into following a few class:
1, single probe type
Single probe is at present common pulse-taking instrument probe form.Single probe can a bit position certain comparatively accurately, and gathers pulse condition information, but not too identical with the theory of feeling the pulse of Traditional Chinese Medicine three body parts and nine pulse-taking sites.
2, two probe types
On the basis of single probe, the people such as Tang Weichang have designed two probe combined type pulse image sensors.Recording respectively pulse by peripheral sensor and central sensor beats making a concerted effort and the power of vertical direction of power, skin tangential force etc.By being distinguished, power can analyze more accurately some mechanical index.
3, three probe or many probe types
Three probe types are not also very extensive at present, according to consulting reference materials, there is now array type pulse-taking instrument, by arranging multiple sensing points, in the time surveying pulse condition information, the pulse condition gathering is a little carried out to analyzing and processing, and the signal that can take out three the most suitable points uses as cun, guan and chi, three places at the wrist where the pulse is usually taken signal.The method is efficient and convenient, but it is comparatively coarse to get arteries and veins form, lacks the individuation targeting scheme " varying with each individual " according to different experimenter's situations, and has larger difference between Traditional Chinese Medicine feeling the pulse.
4, attached finger formula
Be that doctor is fixed on transducer on the finger of oneself, the process of then feeling the pulse according to Traditional Chinese Medicine is felt the pulse, and can transmit the information of collection and carry out record analysis in the process that transducer is felt the pulse doctor.The method is simple to operate, but when practical operation, easily occurs that transducer installs the unstable situations such as signal that maybe cannot collect, and repeatable poor.
In sum, although the development of pulse-taking instrument has obtained good development, fail to be used widely.Tracing it to its cause, is mainly that the problems such as personalized location and single-point acquiring cause the practical problems such as loaded down with trivial details consuming time, the stability of pulse-taking instrument harvester use, poor accuracy.Existing product and technology are varied, although respectively there is advantage, are not still well positioned to meet the needs of present medical development.Relative analysis can find, for the better form of simulation TCM pulse diagnosis three body parts and nine pulse-taking sites, adopting three sonde-type pulse-taking instruments of the piezoelectric transducer of 3 synchronous self-movements should be the selection that can meet the developing direction of present pulse-taking instrument.
