61, wave of oscillation extraction unit 62 and blood pressure parameter calculating part 63；Linearly inflate control portion 61, be used for controlling fingerstall 1 or cuff 3 is real
Existing different mode of operation；Wave of oscillation extraction unit 62, for digital signal produced by AD acquisition module 18 is extracted, with
Analyze and obtain final pressure wave of oscillation signal；Blood pressure parameter calculating part 63, for being obtained according to wave of oscillation extraction unit 62
End pressure wave of oscillation signal and calculate blood pressure parameter value.
The survey meter of blood pressure of the present invention has following several mode of operations:
1, correction mode
Booster air pump 51, inflates to cuff 3 and fingerstall 1 simultaneously, and fingerstall 1 only needs to maintain lower pressure (50mmHg) to survey
Feel one's pulse ripple, so when fingerstall 1 arrives the force value set, such as during 45-55mmHg, air pump 51 then suspends fingerstall 1 dozen
Gas, and preserve pressure in fingerstall 1；Air pump 51 then continues to inflate cuff 3, until the pressure in cuff exceedes contraction pressure (normally
The contraction pressure value of people the chances are 110-130mmHg), then cuff 31 is carried out homogenous linear venting, until the pressure in cuff
Less than shrinking pressure, cuff pressure sensor first the pulse wave peak value that detect adopted in the cuff pressure signal collected is
Contraction pressure after calibration, then by vent valve, cuff and air bag are carried out Rapid degassing, complete correction work.
2, fingerstall works independently and measures blood pressure
After the survey meter of blood pressure of the present invention has been calibrated, as in figure 2 it is shown, need initialization apparatus, then by fingerstall 1 cincture
On the finger of user；It is first linearly to inflate pattern and second and linearly inflate pattern by the Working mode set of fingerstall 1 again, and
Set the first pressure change rate K linearly inflated in pattern in fingerstall 1 air bag1(such as 40/fs) and maximum pressure P1(such as 40mmHg)
And second pressure change rate K linearly inflated in pattern in fingerstall 1 air bag2(such as 120/ (14*fs)) and maximum pressure P2(as
160mmHg)；
Additionally, in order to enable farthest to shorten the measurement time, as it is shown in figure 5, pattern of linearly can inflating first sets
For quickly inflating the stage (pressure from 0 to 40mmHg, about 1s), second linearly inflate pattern for inflating the stage at a slow speed (pressure from
40 to 160mmHg, about 14s).It is to say, use the mode realizing linearly inflating of survey meter of blood pressure of the present invention, single
The time measured only needs about 15S, and the most shorter, (time of single measurement needs 45-60s with existing blood pressure lowering measuring method
) significantly shorten the measurement time, such that it is able to improve the comfort level of user significantly.Certainly, above-mentioned first linear
Pattern and second of inflating linearly is inflated measurement time of pattern, can be according to the different value of the requirements set of different user.
Air pump 51 starts, and cuff pressure sensor 21 and AD acquisition module 18 Real-time Collection refers to the pressure P in air bag also
Calculate pressure change rate K, at P less than P1Before, air pump voltage U is regulated in real time by PID to follow the tracks of target, pressure rate of change K1,
Until realizing the first pressure linearly inflated in pattern in fingerstall 1 air bag linearly rise to P from 01；
In like manner, at P more than P1And less than P2Before, air pump voltage U is regulated in real time by PID to follow the tracks of target, pressure change
Rate K2, until realizing the second pressure linearly inflated in pattern in fingerstall 1 air bag from P1Linearly rise to P2；
If P is more than P2, then air pump 51 stops inflating.
It is to say, linearly inflating of fingerstall 1 is controlled air pump in real time and realize by PID, the most as shown in Figure 4,
Using real-time change rate K of pressure in fingerstall 1 air bag as PID controlled quentity controlled variable, by pressure change rate target setting value (K1With
K2), current pressure change rate K in real time obtained with feedback compares, and obtains controlling the input quantity that error controls as PID, then
Being calculated output by increment type PID, (air pump exports the gas of air bag to tolerance Q of air bag to control air pump 1 regulation output
Amount Q is mainly realized by the voltage of control air pump), enter finally by the pressure in cuff pressure sensor detection air bag
Row PID next time adjusts.So, by the rate of change k measured in real time is carried out feedback adjustment, it is possible to accurately ensure to be surveyed
The accuracy of the pressure that amount arrives, 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 the micro-of error
Point, equal to the difference of error current Yu front first-order error；
E is for controlling error: e=K-Kn；KnFor K1Or K2；
K=Pi-P(i-1)；PiFor current collection point force value, P(i-1)Pressure for the previous collection point of current collection point
Value.
By above-mentioned relational expression, it is possible to accurately control the voltage U of air pump, and then air pump regulation can be accurately controlled
Output is to tolerance Q of air bag.
Meanwhile, digital signal produced by AD acquisition module 18 can be extracted to obtain final by wave of oscillation extraction unit 62
Pressure swings ripple signal, as it is shown on figure 3, the extraction flow process of this final pressure wave of oscillation is: first choose P1Above pressure waveform
Data, pass it through the low pass software filtering of 3Hz, then obtain actual ramp signal by least square fitting, by P1With
On raw pressure signal deduct the ramp signal that matching obtains, as shown in Figure 6, the envelope of the wave of oscillation is effective, and algorithm letter
Single, it is beneficial to realize on single-chip microcomputer；Last again through the software high-pass filtering of 0.5Hz, i.e. can get final pressure wave of oscillation letter
Number, effect is as shown in Figure 8.Use the wave of oscillation effect that survey meter of blood pressure of the present invention obtains significantly better than using traditional blood pressure to measure
Instrument uses band filter to grasp the wave of oscillation effect obtained, and effect is the most 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, contraction pressure etc..
