Description
Technical field
The present invention relates to human blood-pressure and measure medical domain, refer more particularly to the preceding N of a kind of basis and clap the pulse signal that searches,, come the self adaptation pulse signal strong and weak, guarantee the blood pressure measuring method of resolution to greatest extent through the resonance-amplifier amplification.
Background technology
Blood pressure is one of physiological parameter of wanting of body weight for humans, is to diagnose the illness, observe therapeutic effect clinically, carry out the important evidence that prognosis is judged.The method of measuring blood pressure mainly is divided into two types of oscillographic method and Ke Shi sound methods.
The main process of oscillographic method is earlier with cuff interruption artery blood flow; In deflation course, detect the gas pressure wave of oscillation in the cuff; Select wave of oscillation amplitude maximum point as a reference,, calculate the value of systolic pressure, diastolic pressure according to the position of clinical statistics rule differentiation systolic pressure, diastolic pressure correspondence.
Ke Shi sound method is with cuff interruption artery blood flow, and slowly venting is listened to pulse sound with stethoscope simultaneously then, can hear powerful pulse sound through stethoscope, and waiting a moment lightens slowly, until hearing very steadily the calibration normal pulse sound of fighting.Pressure corresponding when hearing pulse sound for the first time is exactly systolic pressure; Continue venting, the pressure that last pulse sound is corresponding is exactly diastolic pressure.Ke Shi sound method is the actual goldstandard of clinical blood pressure measurement.
Two kinds of methods all are the relations according to the shape of pulse signal waveform and systolic pressure, diastolic pressure, confirm the position on the corresponding pressure curve of systolic pressure, diastolic pressure, and then the value of definite systolic pressure, diastolic pressure.The complete sum resolution of pulse signal waveform can influence the accuracy of blood pressure measurement, but pulse signal intensity individual variation is very big; Under hardware sampling resolution one stable condition; Guarantee pulse signal not by truncation, will cause the weak sampling resolution of pulse not enough, influence certainty of measurement.
Summary of the invention
To the measurement error that causes because of the individual variation of pulse signal intensity in above-mentioned oscillographic method and the auscultation; N clapped the pulse signal that searches before the technical issues that need to address of the present invention provided a kind of basis; Through the resonance-amplifier amplification; Come the self adaptation pulse signal strong and weak, guarantee the blood pressure measuring method of resolution to greatest extent.
In order to address the above problem, the blood pressure measuring method of the strong and weak Self Adaptive Control of a kind of pulse of the present invention, realize through following steps:

Clap pulse signal based on preceding N, the adjustment amplifier magnification ratio keeps in the reasonable scope the pulse signal that send sampling;
When measurement finishes, finish the search pulse signal, and based on the amplifier magnification ratio of storing, select suitable multiplication factor, all pulse signals that search in the calculating measuring process are corresponding to the value of this multiplication factor;
According to the corresponding relation of systolic pressure, diastolic pressure and pulse signal waveform, calculate the value of systolic pressure, diastolic pressure, and show measurement result.
The blood pressure measuring method of the strong and weak Self Adaptive Control of above-mentioned pulse, it is further characterized in that: clap the pulse signal that searches according to preceding N, through the resonance-amplifier amplification, come the self adaptation pulse signal strong and weak, guarantee resolution to greatest extent.
The blood pressure measuring method of the strong and weak Self Adaptive Control of above-mentioned pulse, it is further characterized in that: described pulse signal, both comprised the pulse signal that aeration phase produces, also comprise the pulse signal that the venting stage produces.
The blood pressure measuring method of the strong and weak Self Adaptive Control of above-mentioned pulse, it is further characterized in that: described amplifier had both comprised the amplifier that single-chip microcomputer is inner, also comprised outside amplifier.
The blood pressure measuring method of the strong and weak Self Adaptive Control of above-mentioned pulse, it is further characterized in that: the adjusting of described amplifier magnification ratio, both comprised that control unit regulated automatically, also comprise the adjusting that the operator participates in.
Compared with prior art; The invention has the beneficial effects as follows: according to different pulse signal intensity; Through the resonance-amplifier amplification, guarantee that resolution is effectively used, can not cause the generation of the not enough or pulse signal truncation situation of resolution; Under the condition that does not increase cost, true resolution and measurement performance have been improved.
