Abstract
An electronic sphygmomanometer is provided, in accordance with pulsating wave information at the time of pressurizing a cuff (1), finishing pressure is measured by a finishing pressure measurement mechanism (16). In the process of decompression, in case that a blood pressure deciding mechanism (13) decides the cuff pressure at the time of the minimum value of blood pressure is lower than the measured finishing pressure, a finishing measurement judging mechanism (14) judges the finish of the measurement and a quick-speed exhausting mechanism (3) exhausts quickly to the cuff (1) at once. In case that the cuff pressure at the time of the minimum value of blood pressure is not lower than the measured finishing pressure, the measurement is continued, and is finished when the cuff pressure is altered to be lower than the measured finishing pressure, then the quick-speed exhausting mechanism (3) exhausts quickly to the cuff (1) at once. Consequently, in the electronic sphygmomanometer, the fluids in the cuff are enabled to exhaust rapidly and quickly after correctively deciding the minimum value of blood pressure, thereby shortening the pressing time on the upper arms.
Description
Technical field
The present invention relates to measure the electric sphygmomanometer of blood pressure by oscillographic measurement (Oscillometry, オ シ ロ メ ト リ Star Network) method.
Background technology
Fig. 7 is the performance plot of an example of the change of cuff (cuff, the カ Off) internal pressure (below, be called cuff press) in the blood pressure determination.As shown in Figure 7, when measuring blood pressure by oscillometry, in slowly reducing sleeve decompression process with pressure, change with pressure shows as pulsation as sleeve.According to the measurement result of this pulsation, decision maximal blood pressure value and minimal blood pressure value.
Fig. 8 represents transverse axis to deduct fluctuating signal waveform after thereby sleeve reduction amount with pressure is extracted pulsating wave (pulse wave, pulse) composition according to the amount of change with pressure of the sleeve in the decompression process of performance plot shown in Figure 7 as time shaft.Fig. 9 press to revise figure behind the performance plot shown in Figure 8 with transverse axis as cuff.In oscillometry, for example will represent for the first time to press as the maximal blood pressure value, expression will be pressed as the minimal blood pressure value less than the cuff of 70% the pulsating wave peak value of Hmax for the first time greater than the cuff of 50% the pulsating wave peak value of the peak swing Hmax of the fluctuating signal waveform in the decompression process.
In example shown in Figure 9, because begin sextus pulsating wave peak value for the first time greater than 50% of Hmax, so the maximal blood pressure value is 139 from the right.In addition, because begin the 5th pulsating wave peak value for the first time less than 70% of Hmax, so the minimal blood pressure value is 99 from the left side.Usually, the mensuration of blood pressure, for example the state with cuff compressing upper arm carries out, and in order not oppress the congestion that causes etc., preferably shortens the pressing time of upper arm etc. as much as possible.
For this reason, for example, determined the fluid releasing compressing of discharging fast immediately in the cuff after the minimal blood pressure value to get final product.But, the chevron of pulsating wave shown in Figure 9 sometimes of varying with each individual need be observed more than twice, in decompression process, when the minimal blood pressure value of decision is high, in order to determine real pressure value than its low zone, the chevron that occurs suitable pulsating wave sometimes, therefore in minimal blood pressure value decision back till the lower pressure region more, need to continue to measure.Just so-called two mountain countermeasures.
Figure 10 is the performance plot of an example of the fluctuating signal of explanation two mountain countermeasures.In example shown in Figure 10, in decompression process, the pulsating wave of peak swing at first appears becoming, determine 200 and 180 respectively as the first maximal blood pressure value and the first minimal blood pressure value according to it.And then, when continuing to measure, become second peak swing pulsating wave appearance, determine 130 and 90 respectively as the second maximal blood pressure value and the second minimal blood pressure value.At this moment, be respectively 130 and 90 suitable as maximal blood pressure value and minimal blood pressure value.
On the other hand, shorten minute, also can shorten the pressing time of upper arm etc.For example, known have a following electric sphygmomanometer, comprising cuff; The pressing mechanism of pressurization cuff; The mechanism of decompressor of decompression cuff internal pressure; Detect the pressure detecting mechanism that the fluid in the described cuff is pressed; Detect the pulsating wave composition detection mechanism of the pulsating wave composition that is comprised in the output signal of this pressure detecting mechanism; Calculate the pulsating wave amplitude calculation mechanism of pulsating wave amplitude by the pulsating wave composition of this pulsating wave composition detection mechanism detection; In the electric sphygmomanometer according to the pressure value determination means of the output signal decision maximal blood pressure value of the output signal of this pulsating wave amplitude calculation mechanism and described pressure detecting mechanism and minimal blood pressure value, be provided with: pulsating wave information testing agency, it detects sleeve pulsating wave information with pressure; Estimating mechanism, it is according to this detected pulsating wave information, and the sleeve when carrying out maximum pulsating wave generation is with pressure infers and the inferring of maximal blood pressure; And decompression controlling organization, it is in the deflated decompression process of cuff dead slow speed, the maximal blood pressure presumed value of inferring from described estimating mechanism deducts cuff pressure point behind the setting till the cuff pressure point that setting is added after the cuff of maximum pulsating wave when taking place pressed, carry out rapid decompression, finish to measure (for example, with reference to patent documentation 1) at short notice by above setting.
Patent documentation 1: the spy opens flat 4-152933 communique.
As mentioned above, in electric sphygmomanometer in the past, two mountain countermeasures have been studied, because till the cuff that reaches regulation after the decision minimal blood pressure value is pressed, proceed to measure, so the problem of the time lengthening of existence compressing upper arm etc.Particularly, when user is hypertension, after decision minimal blood pressure value, can continue to measure, therefore have the long especially problem of time of compressing upper arm etc. in considerable time.
In addition, in described patent documentation 1 disclosed electric sphygmomanometer, when existence deducts cuff pressure point behind the setting and begins to have real minimum point pressure value during the rapid decompression till cuff when maximum pulsating wave is taken place is pressed the cuff pressure point that adds setting from the maximal blood pressure presumed value, can not try to achieve the problem of this real minimal blood pressure value.And then in patent documentation 1 disclosed electric sphygmomanometer, in decompression process, the aperture of correctly regulating the air bleeding valve of cuff according to the mode of returning the dead slow speed decompression again through rapid decompression from dead slow speed decompression is extremely difficult.Therefore, patent documentation 1 disclosed electric sphygmomanometer lacks realization property.

The specific embodiment
Below, with reference to accompanying drawing, the preferred forms of the related electric sphygmomanometer of this invention is described in detail.Fig. 1 is the block diagram of the formation of the relevant electric sphygmomanometer of expression embodiments of the present invention.As shown in Figure 1, electric sphygmomanometer possesses cuff 1; Pressing mechanism 2; Exhaust gear 3 rapidly; The mechanism of decompressor 4; Pressure detecting mechanism 5; Microcomputer (below, be made as MPU) 6 and display part 7.Cuff 1 is with pressing mechanism 2, exhaust gear 3, the mechanism of decompressor 4 and pressure detecting mechanism 5 are connected by conduit 8 rapidly.
The mechanism of decompressor 4 stops to press the output signal of calculation mechanism 17 to begin the dead slow speed decompression of the pressure of cuff 1 according to pressurization, and according to the output signal of pressure detecting mechanism 5, and making decompression rate is that the mode of constant speed is controlled.The mechanism of decompressor 4 for example is made of the dead slow speed air bleeding valve that dead slow speed is discharged air in the cuff 1 etc.The pressure in the cuff 1 detects in pressure detecting mechanism 5.Pressure detecting mechanism 5 for example is made of pressure transducer.Maximal blood pressure value and minimal blood pressure value that display part 7 shows by the MPU6 decision.Display part 7 for example is made of display panels, the controlling organization that carries out the demonstration control of this display panels.
MPU6, pulsating wave information testing agency 15, mensuration finish calculation of pressure mechanism 16 and pressurize to stop to press calculation mechanism 17 formations when possessing pulsating wave composition detection mechanism 11, pulsating wave amplitude calculation mechanism 12, pressure value determination means 13, mensuration end decision mechanism 14, pressurization.These mechanisms that constitute MPU6 carry out the piezometry program by MPU6 and realize.
Pulsating wave information testing agency 15 during pressurization, by 1 pressurization of 2 pairs of cufves of pressing mechanism the time, the pulsating wave information that comprises in the output signal of detected pressures testing agency 5.At this moment, the pulsating wave information that pulsating wave information testing agency 15 is detected during pressurization is the differential value (pressing speed) of the pressure in the cuff 1.This is because the caused pressure oscillation of pulsation that detects during cuff 1 pressurization is to be difficult to the little cause (with reference to the pressure process of Fig. 7) of observing such.At this moment, by getting sleeve differential value with pressure, as shown in Figures 2 and 3, pulsating wave is obviously changed.
Fig. 2 is with the performance plot of transverse axis as the sleeve differential value with pressure in the pressure process of time showing performance plot shown in Figure 7.Fig. 3 presses the figure revised behind the performance plot shown in Figure 2 with transverse axis as cuff.In addition, in Fig. 2 and the example shown in Figure 3, limit especially, but be that the mode of 15mmHg/sec is controlled according to pressing speed.
Measure to finish calculation of pressure mechanism 16, the pulsating wave information that pulsating wave information testing agency 15 is detected according to by pressurization the time is calculated to measure and is finished pressure.Cuff when the amplitude of the sleeve differential value with pressure that pulsating wave information testing agency 15 was detected when mensuration finished pressure for example for the expression pressurization is maximum is pressed.Below, with the sleeve differential value with pressure amplitude as differential pulsating wave amplitude.For example during as shown in Figure 3 example, the maximum of differential pulsating wave amplitude is 41mmHg/sec, and the cuff of this moment is pressed and is 121mmHg.Therefore, measuring end pressure this moment is 121mmHg.
Perhaps measure to finish the sleeve differential value with pressure that calculation of pressure mechanism 16 also can pulsating wave information testing agency 15 be detected according to by pressurization the time, calculate the presumed value of minimal blood pressure value, presumed value to this minimal blood pressure value adds setting, and for example the value behind the 20mmHg finishes pressure as measuring.At this moment, when for example describing with example shown in Figure 3, second largest differential pulsating wave amplitude be 34mmHg/sec (=41mmHg/sec-7mmHg/sec).It is not less than differential pulsating wave amplitude maximum (41mmHg/sec) 70%.
The third-largest differential pulsating wave amplitude is 18mmHg/sec (=3 1mmHg/sec-13mmHg/sec), and the cuff of this moment is pressed and is 94numHg.Because it is less than 70% of 41mmHg/sec, so the presumed value of minimal blood pressure value is 94mmHg.This value is added for example 20mmHg, and therefore measuring end pressure is 114mmHg.The reason that adds 20mmHg is to consider the presumed value of minimal blood pressure value and the error between the actual minimal blood pressure value, also to avoid carrying out the dead slow speed decompression process more than necessity for a long time, shorten the cause of pressing time at the blood pressure determination positions such as upper arm of cuff 1 as much as possible.More than, measure the computational methods that finish pressure with the explanation of two kinds of methods, but measure finish calculation of pressure mechanism 16 with arbitrary value as mensuration end pressure, can suitably select in the design phase according to the standard of electric sphygmomanometer etc.
Pressurization stops to press calculation mechanism 17, the sleeve differential value with pressure that pulsating wave information testing agency 15 is detected during according to pressurization, and the pressurization that stops cuff 1 pressurization that calculating pressing mechanism 2 is carried out stops to press.Pressurization stops to press calculation mechanism 17, and the cuff when being maximum with differential pulsating wave amplitude for example presses the pressure behind the adding 60mmHg to stop to press as pressure.When cuff 1 pressurization, cuff is pressed to reach and is pressurizeed when stopping to press, and thinking to pressurize stops to press the output signal of calculation mechanism 17.Stop the driving of pressing mechanism 2 thus, replace, open the dead slow speed air bleeding valve that constitutes the mechanism of decompressor 4, the dead slow speed decompression of beginning cuff 1.
The pulsating wave composition in the output signal that is superimposed upon pressure detecting mechanism 5 by the pressure in the mechanism of decompressor 4 slow decompression cufves 1 time, detects in pulsating wave composition detection mechanism 11.Pulsating wave amplitude calculation mechanism 12 is calculated the pulsating wave amplitude in the decompression process according to the pulsating wave composition that is detected by pulsating wave composition detection mechanism 11.Pressure value determination means 13 is according to the output signal of pulsating wave amplitude calculation mechanism 12 and the output signal of pressure detecting mechanism 5, by the blood pressure decision algorithm of known oscillometry, decision maximal blood pressure value and minimal blood pressure value.
If during pressure value determination means 13 decision minimal blood pressure values, the cuff pressure ratio mensuration end pressure that is detected by pressure detecting mechanism 5 is low, then measures end decision mechanism 14 and judges the mensuration end.When the periodic cuff pressure ratio mensuration of determining of minimal blood pressure value end pressure is low, continue the dead slow speed aerofluxus of the cuff 1 of the mechanism of decompressor 4, continue blood pressure determination.And, when cuff pressure ratio mensuration end pressure is low, measures end decision mechanism 14 judgement mensuration and finish.
When measuring the 14 judgement mensuration end of end decision mechanism, carry out the output signal of (assert) mensuration end decision mechanism 14.Thus, open and constitute the air bleeding valve rapidly of exhaust gear 3 rapidly, the aerofluxus rapidly of beginning cuff 1.In addition, when measuring the 14 judgement mensuration end of end decision mechanism, show minimal blood pressure value and maximal blood pressure value at display part 7.
Fig. 4 is the flow chart of the blood pressure determination processing sequence of the relevant electric sphygmomanometer of expression embodiments of the present invention with Fig. 5.Fig. 5 is the continuation of Fig. 4.After the upper arm of measured value twined cuff 1, as shown in Figure 4, the beginning blood pressure determination was handled, and at first begins the pressurization of cufves 1 by pressing mechanism 2, compressing mensuration person's upper arm (step S1).And, the pulsating wave (step S2) when pulsating wave information testing agency 15 judges whether to detect pressurization when pressure detecting mechanism 5 and pressurization.
(step S2: not), continue the pressurization to cuff 1 of pressing mechanism 2, in the time can not detecting pulsating wave up to detecting pulsating wave.In the time can detecting pulsating wave (step S2: be), pulsating wave information testing agency 15 computing differential pulsating wave amplitudes (step S3) during by pressurization.And, with the differential pulsating wave amplitude that calculates and the pulsating wave corresponding with it begin press (cuff of the starting point of this pulsating wave is pressed) to be stored in the memorizer in the MPU6 (step S4).This memorizer omits in Fig. 1.
Pulsating wave information testing agency 15 judges whether the differential pulsating wave amplitude that calculates at step S3 is maximum (step S5) during then, by pressurization.Set the peaked zone be used to store differential pulsating wave amplitude in the memorizer in MPU6, relatively carry out this judgement being stored in the maximum of the differential pulsating wave amplitude in this zone and differential pulsating wave amplitude that step S3 newly calculates.But, when calculating differential pulsating wave amplitude for the first time, be used to store on the memorizer in the peaked MPU6 of differential pulsating wave amplitude the zone what all do not deposit, judge that therefore the differential pulsating wave amplitude that calculates for the first time is for maximum.At step S5, the differential pulsating wave amplitude that calculates at determining step S3 (step S5: be) when maximum upgrades the maximum (step S6) of differential pulsating wave amplitude.And, stop to press calculation mechanism 17 to calculate pressurization by pressurization and stop to press (step S7).In addition, finish calculation of pressure mechanism 16 calculating mensuration end force value (step S8), enter into step S9 by measuring.
(step S5: not), omit step S6, enter into step S9 when on the other hand, the differential pulsating wave amplitude that is calculated at step S4 is not maximum to S8.Usually, carry out step S6～S8 once more than, pressurization stopped to press and measure finish force value calculate respectively once above after, at step S5 for not.
At step S9, judge by pressing mechanism 2 whether the current pressure of cuff 1 is higher than the pressurization that is calculated at step S7 and stops to press (step S9).In high (step S9: be), finish the pressurization (step S10) of 2 pairs of cufves 1 of pressing mechanism.(step S9: not), return step S1, repeating step S1～S9 is not till current cuff pressure ratio pressurization stops to press height in high.
After the pressurization of cuff 1 stops, by the dead slow speed decompression (step S11) of the mechanism of decompressor 4 beginning cufves 1.And, the pulsating wave (step S12) when extracting decompression by pulsating wave composition detection mechanism 11 and pulsating wave amplitude calculation mechanism 12.Promptly the pulsating wave composition that is comprised in the output signal by 11 detected pressures testing agencies 5 of pulsating wave composition detection mechanism according to this pulsating wave composition, calculates the pulsating wave amplitude by pulsating wave amplitude calculation mechanism 12.The speed of dead slow speed decompression for can be detected the decompression rate of pulsating wave composition size by pulsating wave composition detection mechanism 11, is controlled to be with the roughly constant speed decompression of 4.5mmHg/sec.
Then, by pressure value determination means 13, calculate maximal blood pressure value and minimal blood pressure value (step S13).(still, till can calculating the minimal blood pressure value, when the pressure of cuff 1 did not have abundant blood pressure lowering, the pulsating wave extraction of decompression of the dead slow speed of step S11 and step S12 repeatedly was till can calculating the minimal blood pressure value.) and, judge by measuring end decision mechanism 14 whether the current pressure of cuff 1 finishes force value low (step S14) than the mensuration that step S8 calculated.In low, (step S14: be), measure to finish judging that structure 14 is judged finishes to measure, and carries out the aerofluxus rapidly (step S15) of cuff 1 by exhaust gear 3 rapidly.
In addition, show maximal blood pressure value and minimal blood pressure value at display part 7.And, finish above-mentioned a series of blood pressure determination and handle.(step S14: not), return step S11, repeating step S11～step S14 till current cuff pressure ratio mensuration end force value is low, does not continue to monitor whether there is the minimal blood pressure value in the lower zone of the pressure of cuff 1 in low.
As described above, according to embodiment, in the decompression process of cuff 1, during by pressure value determination means 13 decision minimal blood pressure values, if it is low that the cuff pressure of this moment finishes force value than the mensuration of measuring 16 calculating of end calculation of pressure mechanism, then finish to measure immediately, cuff 1 is carried out aerofluxus rapidly, therefore can receive such effect of time that can shorten compressing upper arm etc. easily.In addition, measure and finish pressure when low in determine periodic cuff pressure ratio of minimal blood pressure value, continue the mensuration of blood pressure, till cuff pressure ratio mensuration end pressure is low, therefore under the situation as shown in figure 10, even when calculating the minimal blood pressure value in the high zone of the pressure of cuff 1 mistakenly, also can reach and correctly calculate the effect of measuring blood pressure once more.
On the other hand, the electric sphygmomanometer that embodiment is relevant during for shown in Figure 6 two mountain figures, has the advantage that can correctly determine the minimal blood pressure value.For the mountain shape occurs twice, there is the such figure of minimal blood pressure in two mountain figures shown in Figure 6 on high-tension side mountain.In such figure, can think as present embodiment, in pressure process, become and pulse when inferring the minimal blood pressure value, because the pulsation that can detect in the pressure process is few, therefore can not judge that there are two in the mountain shape, shown in the dotted line of Fig. 6, see a mountain shape.At this moment, the original minimal blood pressure value that should be positioned on high-tension side mountain shape may be speculated as and be positioned at the part that is considered as a mountain mountain shape, low-pressure side shape.
Even under these circumstances, if the electric sphygmomanometer of embodiment also can correctly be measured blood pressure.Relative therewith, in described patent documentation 1 disclosed electric sphygmomanometer, to return once more the process of dead slow speed decompression through rapid decompression from the dead slow speed decompression, the possibility of real minimal blood pressure value appears in the stage that may exist in rapid decompression.At this moment, can not detect real minimal blood pressure value, and detect lip-deep minimal blood pressure value.That is, in patent documentation 1 disclosed electric sphygmomanometer, the problem of blood pressure can not be correctly measured in existence.Among above the present invention, be not limited to above-mentioned embodiment, also can carry out various distortion.
