The number one killer of health, it has become as the major public health problem in China and the world.The serious health of impact people and
Quality of life, therefore, the early prediction to cardiovascular disease and mid-term diagnoses and treatment, have and its important meaning.
Blood pressure is the weight of the physiological parameters such as reflection cardiac pumping function, vascular resistance, viscosity of blood and whole body blood volume
Want index, be clinically widely applied.Blood pressure has and significantly changes over characteristic, the single carrying out in clinic or
Few time blood pressure measurement can not reliably reflect the situation under the fluctuation and active state of blood pressure.Ambulatory blood pressure monitoring is at 24 hours
A kind of diagnostic techniquess of blood pressure under interior automatic discontinuous property Timing measurement daily life state.Because ambulatory blood pressure overcomes clinic blood
Pendulous frequency is less for pressure, the limitation of observational error and White coat effect etc., can objectively reflect practical level and the ripple of blood pressure
Dynamic situation, therefore makes a definite diagnosis, judges " white coat hypertension " and intractable hypertension, evaluates anti-height in clinical doubtful hyperpietic
The aspect such as the curative effect of blood pressure medication and guiding treatment has obtained increasingly being widely applied.Ambulatory blood pressure monitoring typically adopts oscillography

Row carry out curve fitting, static pressure (flip-flop of pressure in cuff) value, as mean pressure corresponding to matched curve maximum；
Obtain systolic pressure amplitude and diastolic pressure amplitude using maximum amplitude and amplitude coefficient, then obtained by matched curve corresponding quiet
Pressure value, as systolic pressure and diastolic pressure.
Conventional dynamic blood pressure instrument is to increased Timing measurement on the basis of electric sphygmomanometer, and reduces the body of sphygomanometer
Long-pending, to reach the 24 hours blood pressure information of acquisition that is easy to carry.It is limited in that, measurement brachial arterial pressure is on sleep impact
Larger, nighttime blood pressures measurement accuracy is vulnerable to impact, and measurement frequency is relatively low simultaneously, if effective pendulous frequency not enough measurement sum
70%, measurement data is then invalid.
Existing pressure oscillation ripple adopts upper arm cuff measuring method mostly, needs a period of time to block brachial artery blood completely
Stream, repeatedly measurement will lead to the numbness of whole upper arm and the congestion of measurement position, and pump quickly inflate during the noise that sends
Larger, easily user's sleep is impacted, the accuracy of impact night measurement.Meanwhile, existing pressure oscillation ripple is adopted mostly
Use blood pressure lowering measuring method, lead to single measurement overlong time (45-60s), Consumer's Experience is poor.
Patent documentation CN101612039A discloses a kind of self-adaption blood pressure detector, and this device can be according to measured
The linear aeration speed of heart rate Automatic adjusument, eliminate the impact to testing result for the individual variation, detection time is short, testing result
Accurately.But this device is mainly the speed adjusting linear inflation by the heart rate according to measured, testing result accurate
Property has much room for improvement.

Amount Q is mainly realized by controlling the voltage of air pump), detect that the pressure in air bag to enter finally by cuff pressure sensor
Row PID adjustment next time.So, by carrying out feedback adjustment to the rate of change k measuring in real time, can accurately ensure to be surveyed
The accuracy of the pressure measured, thereby may be ensured that stability and the accuracy of air pressure wave of oscillation signal.
Wherein, above-mentioned air pump voltage U is tried to achieve by following relational expression：
U=Kp*e+Ki* ∑ e+kd* Δ e
Wherein：Kp is proportional unit coefficient；Ki is integral unit coefficient；Kd is differentiation element coefficient；Δ e is for by mistake
The differential of difference, equal to the difference of error current and front first-order error；
E is to control error：E=K-Kn；Kn is K1Or K2；
K=Pi-P(i-1)；PiFor current collection point pressure value, P(i-1)Pressure for the previous collection point of current collection point
Value.
By above-mentioned relational expression, the voltage U of air pump can be accurately controlled, and then air pump can be accurately controlled and adjust
Export tolerance Q of air bag.
Meanwhile, wave of oscillation extraction unit 62 can be extracted to digital signal produced by AD acquisition module 18 to obtain finally
Pressure swings ripple signal, as shown in figure 3, the extraction flow process of this final pressure wave of oscillation is：Choose P first1Above pressure waveform
Data, passes it through the low pass software filtering of 3Hz, then obtains actual ramp signal by least square fitting, by P1With
On raw pressure signal deduct the ramp signal that matching obtains, as shown in fig. 6, the envelope effect of the wave of oscillation is good, and algorithm letter
Single, realize beneficial on single-chip microcomputer；Finally again through the software high-pass filtering of 0.5Hz, you can obtain final pressure wave of oscillation letter
Number, effect is as shown in Figure 8.The wave of oscillation effect being obtained using this utility model survey meter of blood pressure is significantly better than and adopts traditional blood pressure
The wave of oscillation effect that measuring instrument is obtained using band filter behaviour, effect is specifically as shown in Figure 7.
Finally, the final pressure wave of oscillation signal meter that blood pressure parameter calculating part 63 can be obtained according to wave of oscillation extraction unit 62
Calculation draws blood pressure parameter value, such as mean pressure, diastolic pressure, systolic pressure etc..
