Technical field
The present invention relates to human blood-pressure and measure medical domain, refer more particularly to a kind of use mould plate technique, according to measured's pulse signal feature, comprise the pulse signal of oscillographic method and auscultation generation, with other information in measuring process, comprise inflation and venting speed, user is segmented, different technical parameters is used to different measuring person, carries out the blood pressure measuring system of the calculating of systolic pressure and diastolic pressure location lookup and value.
Background technology
Blood pressure is one of physiological parameter of wanting of body weight for humans, is the important evidence diagnosing the illness clinically, observe therapeutic effect, carry out Index for diagnosis.The method of Measure blood pressure is mainly divided into oscillographic method and Korotkoff's Sound method two class.
The main process of oscillographic method first uses cuff interruption artery blood flow, detects the gas pressure wave of oscillation in cuff in deflation course, selects wave of oscillation amplitude maximum as a reference point, differentiate systolic pressure and diastolic pressure according to clinical statistics rule.Because the differentiation of oscillographic method systolic pressure and diastolic pressure obtains based on clinical probability statistical law, do not consider individual variation, when therefore oscillographic method is measured individual, adaptability is poor, may occur larger difference.
Korotkoff's Sound method is with cuff interruption artery blood flow, then slowly exits, listens to pulse sound simultaneously with stethoscope, can hear powerful pulse sound, wait a moment and lighten slowly by stethoscope, until hear very steady compared with normal pulse sound.When first time hears pulse sound, corresponding pressure is exactly systolic pressure; Continue venting, the pressure that last pulse sound is corresponding is exactly diastolic pressure.Korotkoff's Sound method is the actual goldstandard of clinical blood pressure measurement.But the method exists some problems, operate more complicated, depend on the subjectivity of people, repeatability is poor.
Two kinds of methods are all the relations according to the shape of pulse signal waveform and systolic pressure, diastolic pressure, determine the position on the corresponding pressure curve of systolic pressure, diastolic pressure, and then determine the value of systolic pressure, diastolic pressure.Each producer, according to statistics rule, uses specific calculating parameter, according to pulse signal waveform and the pressure waveform of each measurement, calculates the value of systolic pressure, diastolic pressure.Because everyone pulse signal waveform is different, the calculating parameter being applicable to particular individual is also different, and the technical parameter in electric sphygmomanometer just has very large individual variation error to a lot of individuality.When being subject to the interference such as motion, electromagnetism, noise, be easy to cause very large disturbance to pulse wave, Measurement Algorithm is difficult to all reject interference, causes larger measured deviation.
Summary of the invention
For in above-mentioned oscillographic method and auscultation because of measurement error that the individual variation of pulse signal waveform causes, and by moving, electromagnetism, noises etc. disturb the measurement error caused, the technical issues that need to address of the present invention are to provide one and make purpose processor, the pulse signal waveform produced in process measuring process, comprise the pulse signal waveform of oscillographic method and auscultation generation, control to detect inflation and venting speed, according to the feature of pulse wave and inflation/deflation speed, identify user, find closest to feature templates, namely best technical parameter, at the end of measurement, the system of systolic pressure and diastolic blood pressure values is calculated by the corresponding parameter of this template.
In order to solve the problem, technical scheme of the present invention is: a kind of blood pressure measuring system adopting template to segment measuring object, uses pressure and pulse signal detection device, detected pressures and pulse signal, and be transferred to processing unit, it is characterized in that, described processing unit comprises:
