Description
Technical field
This utility model belongs to the technical field of medical diagnostic equipment, is specifically related to a kind of electropulsograph.
Background technology
Pulse condition is the Diagnostics of Chinese Medicine noun.Rely on finger that patient's radial artery is carried out pulse-taking, what namely be commonly called as feels the pulse, and is one of important means of traditional traditional Chinese medical science enforcement medical diagnosis on disease.The traditional Chinese medical science imposes different pressure touches by finger to patient's radial artery, and perception patient's the pulse situation of beating under these different pressure states respectively.Obtain the alleged pulse condition of the traditional Chinese medical science.Comprise frequency, the rhythm and pace of moving things, fullness degree, unobstructed situation, the amplitude of easing up, fluctuating of kinetic potential etc.According to Traditional Chinese medical theory, the formation of pulse condition, close with the internal organs qi-blood relationship.As heart governing blood and vessels, the convergence of vessels in the lung, The spleen governs the blood, blood stored in the liver, changes of function such as kidney-essence transforming into blood all can cause the change of pulse condition, so different pulse conditions can reflect physiology and the pathological change of internal organs QI and blood.
At present, research and development about the pulse wave spectrum instrumentation have had many achievements, and there have been the patent of many types and product to come out, Chinese patent 200920074537.7 utility models a kind of wrist formula pulse-taking instrument, to comprise that by the nylon bandage positioning component of a sensor cluster aims at the pulse fixed-site on wrist, and carry out pulse condition and detect.Chinese patent 200710181321.6 utility models a kind of pulse-taking instrument that can carry out spectrum analysis, a push rod bottom that places a thrust meter for the chip pulsation detection sensor that picks up pulse condition, thrust meter places on the adjustment support, the pulsation detection sensor accurately can be located with respect to detected part by the position of adjusting push rod, and Accommodation is in the pressure of detected part, measure pulse profile data, the pulse profile data that obtains is carried out spectrum analysis by computer, obtain diagnostic result.
