Description

Periodicity physiological single processing method and system

Technical field

The present invention is about a kind of periodicity physiological single processing method and system, especially finger is a kind of can give digitized disposal route and system with the periodicity physiological signal of human body, resolve into mathematical limit (poles) and residue (residuals) via numerical method, can be suitable for the periodically processing of physiological signal such as human body heartbeat, breathing and potential diagram for the reference of evaluator body-centered reason and physiological situation.

Background technology

Operation meeting in the human body produces some physiological phenomenons naturally, for example heartbeat, breathing and pulse or the like, and the doctor judges changes in health through the sign that these physiological phenomenons provided since ancient times, and then prevention and treatment disease.Traditionally, the traditional Chinese physician in east sees through and feels the pulse, and the doctor of Western medicine in west sees through auscultation with stethoscope and sphygmomanometer, observes the variation of heartbeat, pulse and breathing or the like, in the modern times of electronic technology prosperity, can see through the electron medical treatment equipment these periodic signals are collected the back as preliminary diagnosis.

With the heartbeat is example, the heartbeat of human body has its regular and repeat characteristic, can accurately detect the physiological signal state of human body by ultrasonic or cardiogram, please join Fig. 1, the standard cardioelectric figure that is constituted with a series of ripple group is an example, and each ripple group is being represented each heart beat cycle, include P ripple, QRS wave group, T and involve the U ripple, (1) P ripple wherein: produced by atrial depolarization, be first ripple in the periodic wave group, it has reflected the process of depolarization in left and right atrium; (2) QRS wave group: typical QRS wave group comprises three ripples that closely link to each other, and first downward ripple is called the Q ripple, and the upright ripple of a high point behind the Q ripple is called the R ripple, and downward ripple is called the S ripple behind the R ripple.These three waveforms closely link to each other, and are referred to as the QRS wave group, and have reflected left and right biventricular process of depolarization; (3) T ripple: the T ripple is positioned at after the S-T section, is a lower and long ripple when being, it is that ventricular bipolarization produces; And (4) U ripple: the U ripple is positioned at after the T ripple, and is relatively low little, it is generally acknowledged with " after depolarization " (afterdepolarizations) relevant, it interrupts or follows in process of depolarization, can be left in the basket in the ECG oscillogram usually.

Generally speaking, normal human's electrocardiographic wave has complete tangible wave to be changed, if unusual variation appears in health or when being upset, Electrocardiographic waveform will obviously be different from normal waveform, can judge thus the testee whether health have different, yet the chart of any physiological signal must be by after the doctor's interpretation that was subjected to professional training, just can learn healthy result, if can learn healthy situation, will save the time that obtains the result without artificial interpretation.

Moreover the physiological situation of human body also can be along with psychologic status changes, and is for example excited, nervous, when fearing, health can produce and palpitate quickly, sweat, vasoconstrictive physiological phenomenon, hence one can see that, sees through the observation of any physiological situation, also can obtain the assessment reference of psychological condition.

In view of this, the inventor of this case provides a kind of periodicity physiological single processing method and system, hope can be utilized periodically, and physiological signal has along with time decay and recurrent characteristic, with after signal digitalized in addition relatively and obtain the entry evaluation result, need not see through doctor or healthcare givers to the interpretation of physiological signal, be available for users to prevention as disease and abnormal mind state.

Summary of the invention

Fundamental purpose of the present invention can be handled the physiological signal that periodically occurs in the disposal route that a kind of periodicity physiological signal is provided, and after digitizing and analyzing, provides the reference of judging body physiological state.

Another object of the present invention is in the disposal system that a kind of periodicity physiological signal is provided, see through inductor receiving cycle physiological signal, give digitized processing again, and with reference to a parameter database, obtain an assessment result, for the reference of Human Physiology or psychologic status.

In order to reach above-mentioned goal of the invention, disposal route of the present invention is with the cyclical signal Dj digitizing of human body and is decomposed into limit (Poles) P and residue (Residuals) S, the rate of decay of P representation signal wherein, S represents the contribution margin of this P value, sequence number with the j representation signal, Dj can be the cyclical signal of different qualities, or the different time of the cyclical signal of same characteristic or signal that the position measured, and signal Dj, limit P and residue S satisfy following formula:

$D^j=\underset{i=1}{\overset{m}{\mathrm{\Σ}}}{S^j}_i{e}^{{-P^j}_i}$

Wherein this m value is collected the limit maximum quantity after the cyclical signal of human body decomposes, P ^j _iRepresent j cyclical signal to decompose i the limit in back, S through data ^j _iBe contribution margin or residue at this limit, the big more expression rate of decay of P value is fast more, and also can earlier an outside stimulus be acted on the human body in the said method, this outside stimulus can produce periodic signal or property free period signal is changed, again the cyclical signal of this human body is collected and digitizing, this outside stimulus is voltage, electromagnetic wave, ultrasonic, heat or pressure etc., then further calculates P ^j _i, S ^j _iValue, its each other relation and these data to the variation of time and space (position), for the physiology of judging this human body or the reference of psychologic status.

Periodicity biosignal processing system of the present invention comprises: inductor, and in order to the periodicity physiological signal of sensing human body, and with this physiological signal output; Physiological signal digitized processing device, the physiological signal that receives this inductor is also with this physiological signal digitizing; And the digitized signal processing unit, this processing unit uses above-mentioned disposal route with physiological signal D ^jBe decomposed into limit P ^jAnd residue S ^j, and with P ^j, S ^j, P ^jAnd S ^jEach other with and set up a parameter database for the variation of time or space (position), parameter database or directly judge the reference of physiology or psychologic status thus, and export an assessment result with raw data.
