Description
Technical field
The present invention relates to the test instrunment technical field, is a kind ofly to be the basis with the feeling the pulse principle in the traditional Chinese medical science four diagnostic methods (hope, hear, ask, cut), a kind of pulse wave spectrum appearance that utilizes pick off and computer technology to realize.
Technical background
" hoping, hear, ask, cut " is the important means of fundamental sum of tcm diagnosis; The Chinese physician is through " cutting "---feels the pulse; The pressure that applies varying strength at finger tip understand the pulse condition information that radial artery transmits (be divided into: floating, heavy, slow, several, sliding, puckery, empty, real, long and short, big vast, little, tight, slow, onion, string, leather, jail, moisten, weak, diffusing, thin, lie prostrate, move, urge, knot, regularly intermittent pulse), the pulse condition of the traditional Chinese medical science can be considered patient that the doctor grants feeling the pulse pressure and patient self radial artery fluctuation information comprehensively.
Any test instrunment/instrument all goes down to accomplish test in certain background, and every kind of (instrument) method of testing must be considered the interference of background to the desire detection signal in use, carries out the compensation and the elimination of background.But the relevant report and the patent documentation of existing pulse wave spectrum appearance development are not all considered compensation and elimination to the pulse condition testing background.
Pick off is the critical component of test instrunment, also is one of key factor of whether succeeding in developing of pulse-taking appearance.At present, the pick off that is used for pulse wave spectrum has two types, and one type is sonic transducer, and another kind of is force transducer.And force transducer at present commonly used have two kinds: a kind of is force transducer by the ceramic membrane material, and the minimum dimension of this pick off is generally Ф 18.Another kind is macromolecular material PVDF preparation (film type) force transducer, and the minimum dimension of this pick off is generally Ф 13.Force transducer can produce different potential when receiving different pressures, so be also referred to as piezoelectric transducer.Because the integral width of traditional Chinese medical science radial artery (cun,guan,chi CUN KOU) is not more than 5mm, length is not more than 50mm; With (film type) force transducer during as the signal detecting part of pulse wave spectrum appearance; What record is the mixed information of pulse wave muscle response peripheral with it; Since the sensitivity of film type force transducer with contact (sensitivity) area relation of being proportionate, if sensor area is too little, its insufficient sensitivity; And size is during greater than Ф 5mm, and what record is not again pure pulse wave information.The pulse wave signal that the pulse-taking appearance that adopts force transducer to design at present records has only the disease of coming to go Xu and comes Xu to remove two kinds of waveforms of disease, can't reproduce 27 kinds of pulse conditions of the traditional Chinese medical science, and this size with the pick off that is adopted is closely-related greater than the radial artery lateral dimension.
" pulse condition " is the embodiment of the conceptive internal organs pattern of activity of Chinese medicine, is the human body comprehensive information that is delivered to the cun,guan,chi position through transmission from one meridian to another, network.The interference that the dropout that produced by path and path produce signal is all being contained in the transmission of any information.The information that the extensive degree of the signal that is produced when therefore, sonac is used for pulse wave spectrum, accuracy directly detect internal organs and provided far below B ultrasonic; In addition, sonac can't realize the traditional Chinese medical science floating, in, taking the pulse heavily.Thereby sound transducer is used for pulse wave spectrum and can not on industry, implements basically.
The size of radial artery (arteries and veins cun,guan,chi arteries and veins medically) on the physics is 5mm * 50mm.Test is learned and is gone up the target (system) of this zone definitions for test, the corresponding with it background that then is called.Therefore, the maximum gauge of the responsive part of force transducer unit (comprising encapsulation, protection) should be less than 5mm.Whether the existing sensors size can satisfy this requirement is that the traditional Chinese medical science is affectionately examined the key that can appearance successful Application.The present domestic force transducer that does not still have less than Φ 5.Pressure transducer generally is being used for test gas and liquid traditionally, and existing domestic and international pressure transducer still can't be realized the stress test to solid system on manufacturing process flow and structure.Therefore, existing based on pressure sensor design the pulse wave spectrum appearance because test cell not verified mensuration be the mechanical characteristics of pulse wave fluctuation, just can't confirm also therefore whether these characteristics have one to one with Chinese medicine pulse to concern.
Except that pick off, the critical component of test instrunment also comprises data acquisition unit.In the component parts of pulse wave spectrum appearance, data acquisition unit is to be mature technique at present, need not restudy exploitation, just can on market, obtain stable, data collecting card reliably as long as provide location number, port number or sample frequency parameter.What the research and development of a large amount of in recent years pulse wave spectrum appearance had description 65% or more approximately is the exploitation of data card.Because they do not have clear and definite correlation technique parameter when the pick off type selecting; So in the integrating process of whole instrument; Aspects such as relevant susceptiveness, stability, the linearity, time constant do not have well clear and definite integrated concept, and corresponding result of use will be affected.
Summary of the invention
