Description
Technical field
The present invention relates to bio signal detection field, in particular to a kind of continuous blood pressure detection side of non-invasive
Method, equipment and device.
Background technology
Blood pressure under the measurable personal daily animation of continuous BP measurement function, is studied, continuously according to medical field
Blood pressure measurement can more accurate, more fully reflect the blood pressure overall condition of a people.Such as carry out an ambulatory blood pressure prison round the clock
Survey, it can also be appreciated that the variation tendency of blood pressure.Including decline situation of the blood pressure at night, rising condition when from morning, and one
The overall variability situation of middle blood pressure round the clock.Continuous BP measurement has turned into hypertension and has managed indispensable detection means, is used for
The identification and diagnosis of hypertension, for assessing cardiovascular and cerebrovascular risk, the effect for assessing Treatment of Hypertension.
Wide variety of current non-invasive blood pressure measurement is the measurement of cuff type sphygmomanometer, and measuring method common are manually
Operation measures two kinds based on Korotkoff's Sound measurement and electronic system by oscillographic method, and Korotkoff's Sound mensuration is accepted extensively by medical domain
But need trained personnel to operate, oscillographic method uses simple but there may be on some crowds larger error.Either
Which kind of above-mentioned method, is required for cuff inflation to pressurize due to measuring each time, and pressurization can cause the discomfort of user, frequently pressurization
The sensation of discomfort can be aggravated, while causing certain influence on blood pressure measurement precision.Particularly, at 24 hours, continuous ambulatory blood pressure was surveyed
In amount, medically advise measurement on every 20 minutes of daytime once, every 30 minutes of night measured once, such pressurization measurement frequency pair
It is larger in the influence of user's daily life, sleep quality.
It is theoretical with reference to related academic research from Moens-Korteweg equations in non-cuff type blood pressure measurement field
On give mathematical relationship between pulse wave translation time PTT and blood pressure.According to theory analysis, when human vas foundation elasticity
Modulus E0 does not occur under conditions of several hypotheses establishments such as significant changes, by calibration, can realize one by PTT measurements
The blood pressure determined under precision is calculated.Electrocardio (ECG)+capillary photoelectricity volume ripple is typically used based on this theoretical product
(PPG) method of synchro measure calculates PTT.These methods, the shortcoming of product have the following aspects：A) PTT calculates blood pressure and existed
Academicly there is precondition, calibration process can only ensure accurately to push away when significant changes do not occur for key physiological parameters
Blood pressure is calculated, if significant changes occur for physiological parameter, sphygmomanometer, which calculates accuracy rate, to be declined；B) using the product of these methods
Comprising PTT measuring apparatus, user needs to use cuff type blood pressure measuring to take blood pressure and provides calibration data, and equipment can not be led in itself
It is dynamic to initiate calibration, it is impossible to ensure precision；C) this kind of product measurement is that PTT is not exact value.Within a cardiac cycle, ventricle
At the time of aorta petal is opened, blood is shot up, and artery starts vibrations and forms pulse wave.Therefore surveyed in heart+distal pulse ripple
In ripple conduction time PTT system of feeling one's pulse, at the time of PTT zequins should be that ventricle aorta petal is opened.But, in order to
Convenience is measured, existing product is used as time measurement zequin using electrocardiosignal R peaks mostly.The time so measured is pulse
Ripple arrival time PAT, i.e., from electrocardiosignal R peaks to the time difference of pulse wave characteristic point, rather than accurate pulse wave translation time
PTT.Because electrocardiosignal R peaks, which are not ventricle aortic valve, opens the moment, since electrocardiosignal R peaks to left ventricle
Blood is penetrated, also one pre-ejection time, PEP is designated as.PAT=PEP+PTT, blood pressure is estimated using PAT as PTT approximation
Error can be introduced.
To sum up, there is the inaccurate technical problem of measurement result in existing blood pressure measurement technology.
For it is above-mentioned the problem of, effective solution is not yet proposed at present.
