[the formation explanation of measuring unit of blood pressure 3]
Next, the formation of measuring unit of blood pressure 3 is described.
Measuring unit of blood pressure 3 is made of bandage 31, pressure transducer 32, force (forcing) pump 33, pressurized control section 34, air bleeding valve 35, aerofluxus control part 36 and blood pressure measurement control part 37.
Blood pressure measurement control part 37 is the action of control and management electric sphygmomanometer 1 all sidedly.Particularly, blood pressure measurement control part 37 is exported blood pressure information Kj and suitable notification signal Tp based on pressure signal So and appropriate location detection signal Ms.Blood pressure information Kj is the information of time information when comprising maximal blood pressure value, minimal blood pressure value, Pulse Rate, blood pressure measurement and appropriate location detection signal Ms etc.Suitably notification signal Tp is the appropriate location information that is made of appropriate location detection signal Ms.
The blood pressure information memorizer 372 of blood pressure measurement control part 37 is for the memory element that stores this blood pressure information Kj.
Wherein, the formation of this blood pressure measurement control part 37 is not particularly limited, if consisted of by single chip microcomputer etc., then since can realize small-sized, low consumption is electrochemical, so convenient.
[the formation explanation of notification unit 4: Fig. 1,2]
Next, the formation of notification unit 4 is described with Fig. 1 and Fig. 2.
Secondary display part 412 utilizes labelling, the light corresponding with the grade of appropriate location detection signal Ms to notify.For example, can carry out the following demonstration that utilizes a plurality of labellings, even the grade with appropriate location detection signal Ms is made as 3 stages, when being the appropriate location, show " zero " as grade 3, when departing from a little from the appropriate location, show " △ " as grade 2, when significantly departing from from the appropriate location, show " * " as grade 1.
The grade in 3 stages for example can determine in the following way.
The grade 3 of appropriate location is that the blood pressure measurement position of electric sphygmomanometer 1 is when dropping on the scope of centrifugal dirty right atrium deficiency ± 1cm.The grade 2 that departs from a little from the appropriate location is that the blood pressure measurement position of electric sphygmomanometer 1 is dropped on more than centrifugal dirty right atrium ± 1cm and during the scope of deficiency ± 5cm.The grade 1 that significantly departs from from the appropriate location is that the blood pressure measurement position of electric sphygmomanometer 1 is when being in scope more than centrifugal dirty right atrium ± 5cm.
For each grade, as long as a plurality of threshold values corresponding with grade separately to the amplitude setting of digital signal Do, pulse data Po, and judge above threshold value with whether and to get final product.
In addition, also can utilize the color of LED light to come display level.For example, grade 3 can be made as that " indigo plant ", grade 2 are made as " Huang ", grade 1 is made as " red " etc.Certainly, also can composite marking, light shows.
In example shown in Figure 1, as the example of measurement result, main display part 41 has shown that the maximal blood pressure value is that 120mmHg, minimal blood pressure value are that 80mmHg, Pulse Rate are that 60bpm and measurement are AM7:30 constantly.
In addition, example shown in Figure 1 is the situation that usage flag is notified the appropriate location.The secondary display part 412 of Fig. 1 in position detection signal Ms has shown " zero " labelling in the situation of grade 3.
Notification unit 42 can be made of dynamic speaker, piezoelectric sound component etc.Can utilize alarm sound, voice etc. to notify.Voice are such as being " position of sphygomanometer is the appropriate location " or " position of sphygomanometer is not the appropriate location " etc.
Like this, owing to can utilize light, labelling or voice to guide the appropriate location into, so the measured can correctly take sphygomanometer to appropriate location.
Because when blood pressure measurement, preferably watch with the posture of loosening, so when electric sphygmomanometer is positioned at the chest front, if can notify this situation with voice, alarm sound like this, then need not to hang down first-class, can keep the posture of loosening, very convenient.
[explanation of the mobile status of forearm: Fig. 3]
Next, illustrate that with Fig. 3 the 1st of appropriate location detecting unit 2 moves the mobile status that detecting unit 25 and the 2nd moves the forearm of detecting unit 24 detections.
Fig. 3 (a) is to be shown schematically on the wrist of left forearm 8a of the measured 8 to lay electric sphygmomanometer 1 to Fig. 3 (e), the figure of the mobile status of the forearm till the beginning blood pressure measurement.Fig. 3 (f) represents the from the beginning figure of the state of overhead view the measured, is the figure of the chest front of explanation the measured.
Fig. 3 (a) lays electric sphygmomanometer 1 on the wrist leftward, the state when beginning blood pressure measurement with the switch of right-hand operated operating portion 5.
Fig. 3 (b) and Fig. 3 (c) are the figure of the 1st mobile status of expression forearm (electric sphygmomanometer).The measured is by the mobile left forearm that blows slowly like that of the arrow shown in Fig. 3 (b), and the arrow shown in Fig. 3 (c) is such, makes electric sphygmomanometer 1 move to the chest front 8b of the measured 8.
Here, shown in Fig. 3 (f), chest front 8b is the concept that comprises this meaning of front of health.Because heart mostly is positioned at left breast or keeps right a little from left breast, so when detecting the beating of heart, be fit to be placed on left front., owing to used microwave Doppler sensor 21, so even if be not that left front also can correctly detect beating of heart.For example, even left breast prism (a little on the lower position of top, the oxter of left side abdomen), in the heart the centre, different or even right front also can be detected according to the measured.Therefore, the inventor is the zone of the chest front 8b shown in Fig. 3 (f) with the scope definition of chest front.
Fig. 3 (d) is that the expression mobile status is the figure of the 2nd mobile status.The measured is moved further forearm, makes the appropriate location of electric sphygmomanometer 1 height that such and heart 81 are identical from the position movement of the chest front 8b of Fig. 3 (c) to the arrow as Fig. 3 (d) shown in.
Fig. 3 (e) has represented that electric sphygmomanometer 1 is identical with the height of heart 81, is in the state of appropriate location.
When being in the 1st mobile status, utilization detects the 1st mobile status from the amplitude of the signal of telecommunication Eo of microwave Doppler sensor 21 outputs, when being in the 2nd mobile status, utilize the frequency content of the signal that signal of telecommunication Eo comprises to detect pulse, and seek the appropriate location based on pulse, this will describe in detail in the back.
In the following description, will use microwave Doppler sensor 21, slightly be designated as " microwave detection " based on the method for the action of signal of telecommunication Eo detection of biological body.
[action specification of embodiment: Fig. 2～4]
Next, the action of electric sphygmomanometer is described with Fig. 2～4.
At first, carry out the action specification of appropriate location detecting unit 2.
In Fig. 2, if the measured 8 begins switch with the measurement that electric sphygmomanometer 1 is placed to wrist (not shown) and press operating part, then microwave Doppler sensor 21 is launched the approximately microwave M e of 2.5GHz, and this microwave is reflected by the measured 8, is received by microwave receiver 212 as echo Mt.
After 22 couples of signal of telecommunication Eo of AD converter carry out the AD conversion, it is moved detecting unit 24 outputs as seasonal effect in time series digital signal Do to signal saturation detection section the 23 and the 2nd.
Signal saturation detection section 23 is transfused to digital signal Do, if the data variation amount of digital signal Do surpasses the number of times that has predetermined the regulation amplitude range, then moves detecting unit 24 outputs the 1st mobile status end signal Ds to the 2nd.
At this moment, though not shown, blood pressure measurement control part 37 also can be transfused to the 1st mobile status end signal Ds that signal saturation detection section 23 exports and control notification unit 4, and it is finished with sound, light or verbal announcement the 1st mobile status.
The 2nd move detecting unit 24 with digital signal Do as input, appropriate location detection signal Ms is exported to measuring unit of blood pressure 3.
The 2nd FFT handling part 242 that moves detecting unit 24 is based on the 2nd temporal information T2, and Do accumulates the stipulated time to digital signal, carries out FFT and processes.This FFT processes the fast Fourier transform processing that is used for carrying out input signal.That is, the digital signal Do that accumulates is carried out Fourier transformation, be decomposed into after each signal component, carrying out the processing at each composition of frequency spectrum expression, and exporting to pulse detection section 243 as first-harmonic Bf.
Pulse Rate calculating part 244 calculates Pulse Rate based on pulse data Po, and exports to measuring unit of blood pressure 3 as Pulse Rate signal Mk.
Use Fig. 3 and Fig. 4 to be described in further detail the action that the 1st signal saturation detection section the 23 and the 2nd that moves detecting unit 25 moves detecting unit 24.
Fig. 4 is in order to illustrate that the 1st of appropriate location detecting unit 2 moves that detecting unit 25 and the 2nd moves the action of detecting unit 24 and the oscillogram that schematically shows.Fig. 4 (a) is transverse axis express time T, and the amplitude of longitudinal axis representative digit signal Do has represented digital signal Do, the figure that namely changes from time of the signal of microwave Doppler sensor 21 outputs.
The interval A of Fig. 4 (a) represented after the measurement that wrist is laid electric sphygmomanometer 1 and pressed operating portion begins switch, the time zone of electric sphygmomanometer 1 during near the chest of the measured 8.This has represented that Fig. 3 (a) is to the 1st mobile status shown in Fig. 3 (c).
Dx shown in Fig. 4 (a) represents the 1st saturation threshold, and Dm represents the 2nd saturation threshold.Become the amplitude range Dr of regulation between the 1st saturation threshold Dx and the 2nd saturation threshold Dm.In addition, Ds is the 1st mobile status end signal.
The 1st saturation threshold Dx and the 2nd saturation threshold Dm can use the value that predetermines.Utilize 2 threshold values to set the amplitude range Dr of regulation.In the example shown in Fig. 4 (a), the 2nd saturation threshold Dm is zero, becomes so-called zero saturation threshold, and with the amplitude of the regulation so-called positive saturation threshold of the 1st saturation threshold Dx(as threshold value) between become the amplitude range Dr of regulation.
In interval A(the 1st mobile status) time, owing to the reflection of the microwave of the organism surface of the measured 8 is added the movement of forearm, so Doppler frequency shift increases, it is large that digital signal Do sharply becomes.The number of times that the 1st 23 couples of digital signal Do of signal saturation detection section that move detecting unit 25 have surpassed the amplitude range Dr of regulation carries out instrumentation.And when the number of times of the amplitude range Dr that has surpassed regulation had surpassed stipulated number, signal saturation detection section 23 was detected as being in the 1st mobile status.Stipulated number can wait in advance by experiment selects its number etc. to set.For example, if stipulated number is made as 10 times, then when digital signal Do is 10 times above the amplitude range Dr that stipulates, detect as being in the 1st mobile status.
The interval A ' of Fig. 4 (a) is the part of end of the interval A of Fig. 4 (a), is the time zone of the 1st mobile status when finishing.
As use Fig. 3 (a) illustrates to Fig. 3 (c) and Fig. 3 (f), forearm is significantly moved and the 1st mobile status that forearm moved to the chest front 8b of the measured 8 finishes when electric sphygmomanometer 1 is come the position of close heart of the chest front 8b shown in Fig. 3 (c).That is, if in interval A ' digital signal Do drops into the scope of amplitude range Dr of regulation, be judged as then that forearm does not significantly move, namely the 1st mobile status finishes.With this moment digital signal Do as the 1st mobile status end signal Ds.
Be transfused to from the 1st digital signal Do that moves detecting unit 25 output and carry out signal processing although the 2nd moves detecting unit 24, after being transfused to the 1st mobile status end signal Ds, begin for the first time to carry out this processing.Its reason is not commencing signal processing when the 1st mobile status is unclosed.
The interval B of Fig. 4 (a) represents wrist is retained near the time zone of the state the heart.This has represented that Fig. 3 (d) is to the 2nd mobile status shown in Fig. 3 (e).
Because in interval B, although there is not the larger shift action of forearm, the small size mobile forearm in order to seek the appropriate location is so detect the digital signal Do of the amplitude range Dr that is no more than regulation.Also comprise the waveform that beating of heart causes in the waveform of this interval B.
Fig. 4 (b) is the figure that amplifies a part that has represented the digital signal Do in the interval B shown in Fig. 4 (a).This time zone is made as interval D.The jitter components of the heart of the measured 8 that inclusion test goes out in this digital signal Do, for example P1, P2, P3.
Fig. 4 (c) schematically shows the figure that has carried out the waveform after fast Fourier transform is processed by FFT handling part 242 couples of digital signal Do.That X-axis is that frequency, Y-axis are the frequency spectrum profile of the intensity of the signal of each frequency content.
The 2nd pulse detection section 243 that moves detecting unit 24 calculates pulse data Po based on first-harmonic Bf from the frequency range of stipulating.
Lf shown in Fig. 4 (c) is the 1st frequency threshold, and Hf is the 2nd frequency threshold.Become the frequency range Df1 of regulation between the 1st frequency threshold Lf and the 2nd frequency threshold Hf.This frequency range must be the scope that catches pulse.According to the result of inventor experiment, by for example the 1st frequency threshold Lf being made as near the 0.5Hz, the 2nd frequency threshold Hf is made as near the 3.0Hz, can catch pulse.
The pulse data Po of 245 pairs of inputs of blood pressure measurement detection unit analyzes.Because pulse data Po is the spectrum distribution of frequency content, so can carry out the statistical dispositions such as its frequency content, power level or average, variance, standard deviation.If normally detect pulse data Po, then blood pressure measurement detection unit 245 is judged to be the appropriate location that electric sphygmomanometer is positioned at blood pressure determination, finishes the 2nd mobile status.At this moment, shown in Fig. 3 (e), electric sphygmomanometer 1 is in and the appropriate location of heart 81 for identical height.And blood pressure measurement detection unit 245 is suitable result's appropriate location detection signal Ms to blood pressure measurement to measuring unit of blood pressure 3 output expression results.
Shown in Fig. 4 (c), because the spectrum distribution in the frequency range Df1 of regulation is pulse data Po, so if the 1st frequency threshold Lf and the 2nd frequency threshold Hf are the threshold values that is fit to, then necessarily comprise the waveform that is suitable as pulse.Also can be by statistical disposition, for example calculate the peak value of each waveform that pulse data Po comprises, appearance tendency of utilizing this peak value etc. is judged pulse.For example, can be with the continuous ripple that rises for 2 times of the intensity of waveform as pulse.
And it is the appropriate location that blood pressure measurement detection unit 245 utilizes the result of statistical disposition to determine whether, output appropriate location detection signal Ms.
Appropriate location detection signal Ms can use the numerical value etc. in 1,2,3 these 3 stages of locative suitable degree.For example, can will suitably spend with the intensity of peak value and be divided into 3 stages.Can determine as the strength of peak value is the appropriate location suitably spending, be the position of departing from a little from the appropriate location etc. than locating a little less than it.
Certainly, can one or more threshold value be set to the signal intensity of each frequency content of the longitudinal axis of Fig. 4 (c), divide suitably degree with the value that surpasses this threshold value.In this situation, can set in advance this threshold value, also can carry out statistical disposition to pulse data Po, tendency occur based on it and calculate threshold value and use.
As illustrating, the 2nd action of moving detecting unit 24 is the 1st mobile status end signal Ds control by the 1st output of moving the signal saturation detection section 23 of detecting unit 25, if be not transfused to the 1st mobile status end signal Ds, then the 2nd move detecting unit 24 and do not move.Like this, can guarantee to carry out the 2nd mobile status after the 1st mobile status detects detects.
[action specification of measuring unit of blood pressure 3: Fig. 2]
Next, the action of measuring unit of blood pressure 3 is described with Fig. 2.
In Fig. 2, the blood pressure measurement detection unit 245 of appropriate location detecting unit 2 will be placed in electric sphygmomanometer 1 on the wrist of the measured 8 is exported to measuring unit of blood pressure 3 as appropriate location detection signal Ms with respect to the suitable degree of the position of heart height blood pressure measurement control part 37.
Blood pressure measurement control part 37 is to the display part 41 output appropriate location detection signal Ms of notification unit 4.In the pulse condition display part 415a of the measuring condition display part 415 of display part 41, according to for example grade in 3 stages of appropriate location detection signal Ms, show the labellings such as " zero ", " △ ", " * ".
Blood pressure measurement control part 37 is also exported appropriate location detection signal Ms to the notification unit 42 of notification unit 4.Notification unit 42 is carried out " position of sphygomanometer is the appropriate location " or voice-based notices such as " position of sphygomanometer are not the appropriate location " according to appropriate location detection signal Ms.
Notification unit 42 also can be utilized buzz, according to the grade in 3 stages of appropriate location detection signal Ms and notify with different tone colors; Or the use vibrating motor, notify the grade in 3 stages of appropriate location detection signal Ms with different vibrations.
And blood pressure measurement control part 37 is controlled the action of blood pressure measurement as described below like that based on appropriate location detection signal Ms.
If be made as grade 3 when electric sphygmomanometer 1 is positioned at the appropriate location, then blood pressure measurement control part 37 is when being transfused to the appropriate location detection signal Ms of grade 3, based on the Pulse Rate signal Mk of Pulse Rate calculating part 244, set the condition of pressing speed by pressurized conditions configuration part 371.
As shown in Figure 5, the pressing speed that pressurized conditions configuration part 371 sets can be divided into: in the situation that Pulse Rate is to be 4.0mmHg/sec below the 40bpm, in the situation that Pulse Rate is larger and be to be 8.0mmHg/sec below the 80bpm than 40, in the situation that Pulse Rate is larger and be to be 12.0mmHg/sec below the 120bpm than 80, and in the situation that Pulse Rate larger than 120bpm be these 4 stages of 16.0mmHg/sec.In addition, the condition of pressing speed based on Pulse Rate shown in Figure 5 is an example, if can detect reliably 7 pulses more than clapping in pressurization, then is not limited to above-mentioned example, can be set as various conditions.
If pressurized conditions has been set in pressurized condition configuration part 371, then the 34 output pressurized control signal Kc of 37 pairs of pressurized control sections of blood pressure measurement control part make it control with the pressing speed that sets.The pressurised driving signal Kd that pressurized control section 34 drives force (forcing) pump 33 based on pressurized control signal Kc to force (forcing) pump 33 outputs.After force (forcing) pump 33 receives the pressurised driving signal Kd of pressurized control section 34 outputs, bandage 31 is pressurizeed.
Like this, bandage 31 is by with the pressing speed bandage corresponding with Pulse Rate pressurization, in the pressurization of bandage 31, by pressure transducer 32 pressure of bandage 31 outputed to blood pressure measurement control part 37 at any time.So that the blood vessel of the measuring point of the measured 8 is oppressed, then the pressure vibration corresponding with the pulse of the measured 8 and bandage are pressed stack if bandage 31 is pressurized to the pressure of regulation.Blood pressure measurement control part 37 is based on the pressure signal So by pressure transducer 32 output, detect with bandage press stack based on the pressure vibration of pulse as the pulse amplitude.
The pulse amplitude that comprises among the pressure signal So of blood pressure measurement control part 37 according to pressure transducer 32 based on the pressure value computational methods of oscillography mode, calculates maximal blood pressure value, minimal blood pressure value, Pulse Rate etc.
If blood pressure measurement control part 37 has been obtained maximal blood pressure value, minimal blood pressure value, then pressurized control section 34 is controlled, stop the action of force (forcing) pump 33.
Blood pressure measurement control part 37 is to aerofluxus control part 36 output aerofluxus control signal Hc.The exhaust gas drive signal Hd that aerofluxus control part 36 is controlled air bleeding valve 35 based on aerofluxus control signal Hc to air bleeding valve 35 outputs.
Blood pressure measurement control part 37 as blood pressure information Kj, is exported to the display part 41 of notification unit 4 with the maximal blood pressure value that calculates, minimal blood pressure value, Pulse Rate etc. when discharging the air of bandage.
Supervision to the appropriate location in the blood pressure measurement describes.
In blood pressure measurement, the situation that the height that has an electric sphygmomanometer 1 changes from the height of heart.Even in position begin blood pressure measurement, if put down forearm etc. and depart from from the appropriate location in the way of blood pressure measurement, the pressure value of then measuring is also insincere.When state that the measured so causes that carelessly forearm departs from from the appropriate location etc., even the measured self wants to measure correct blood pressure, in fact also carried out incorrect blood pressure measurement.
In order to avoid such situation, electric sphygmomanometer 1 can also be proceeded microwave and detect after this position become the appropriate location and begun blood pressure measurement, whether monitors the appropriate location.
In the end of the 2nd mobile status and after having begun blood pressure measurement, also continue to monitor the peak value of pulse data Po, output appropriate location detection signal Ms.
When in position detection signal Ms changes, use notification unit 4 to notify.Such as notice " having departed from from the appropriate location " etc.In addition, when the grade of appropriate location detection signal Ms significantly changes, interrupt blood pressure measurement.For example, during grade 1 when the grade 3 from the appropriate location time is changed to and significantly departs from from the appropriate location, electric sphygmomanometer 1 departs from from cardiac position, and electric sphygmomanometer 1 utilizes notification unit 4 notices " termination blood pressure measurement ", thereby interrupts blood pressure measurement.
Although also exist owing to the reason of the measured rather than based on the blood pressure measurement of appropriate location, in any case all want to know the situation of pressure value.At this moment, measurement that also can operating operation section begins switch etc., begins forcibly blood pressure measurement.
[explanation of motion flow: Fig. 6]
Next, mainly use Fig. 6, the motion flow of the blood pressure measurement of electric sphygmomanometer 1 is described in detail in detail.Fig. 6 is that explanation is laid electric sphygmomanometer 1 in wrist, the flow chart of the action till finishing to blood pressure measurement.Below, action step slightly be designated as S1, S2 ..., Sn.
At first, the measured 8 is laid electric sphygmomanometer 1 in wrist, and the measurement start button (S1) of press operating part.
So, begun microwave detection (S2) by appropriate location detecting unit 2 shown in Figure 3.
The measured 8 makes the wrist of having laid electric sphygmomanometer 1 move to chest front (the 1st mobile status).During this period, the number of times that the amplitude by 23 couples of digital signal Do of signal saturation detection section surpasses the amplitude range of regulation carries out instrumentation.If the significantly mobile end of forearm, then digital signal Do drops into the amplitude range Dr of regulation, and the 1st mobile status finishes.If the 1st mobile status finishes, then signal saturation detection section 23 exports the 1st mobile status end signal Ds(S3: "Yes").
At this moment, although in Fig. 3 and Fig. 6, do not illustrate, but also can be the 1st mobile status end signal Ds that blood pressure measurement control part 3 is transfused to 23 outputs of signal saturation detection section, control by the notification unit 42 to notification unit 4, come the information that finishes with sound, light or verbal announcement " sphygomanometer is in suitable position " grade in an imperial examination 1 mobile status.
In the unclosed situation of the 1st mobile status, blood pressure measurement control part 3 is at the instrumentation state based on signal saturation detection section 23, being judged as the measured 8 does not also make wrist fully incorrect near breast or close mode, (S3: "No") in the unclosed situation of the 1st mobile status, by the notification unit 42 of control notification unit 4, carry out the verbal announcement (S4) of " position of sphygomanometer and incorrect " or " please again with sphygomanometer near chest " etc.
For sphygomanometer has been carried out after the verbal announcement near chest, turn back to S3, carry out the detection of the 1st mobile status.Repeatedly carry out the processing of S3 and S4, until detect till the end of the 1st mobile status.
If the 1st mobile status finishes, then the 2nd FFT handling part 242 that moves detecting unit 24 shown in Figure 3 is accumulated the stipulated time (S5) based on the 2nd temporal information T2 to digital signal Do.

Pulse Rate calculating part 244 calculates Pulse Rate (S7) based on pulse data Po.
Blood pressure is judged measurement section 245 according to the detection of the pulse data Po of the frequency range that drops on regulation, is judged to be at chest front electric sphygmomanometer 1 to be in identical height with heart.This is the detection of end (S8: "Yes") of the 2nd mobile status.
Wherein, the frequency range of regulation needs only to wait by experiment and obtains in advance, for example the spectrum distribution of pulse can be made as the scope of 0.5Hz to 3.0Hz.
Judging measurement section 245 when blood pressure can not detect pulse data Po and can't be judged to be that (S8: "No"), blood pressure measurement control part 37 carries out warning tones, warning demonstration based on appropriate location detection signal Ms when chest front electric sphygmomanometer 1 is in identical height with heart.For example, use (S9) such as notification unit 4 notices " please sphygomanometer upwards being lifted again " or " please with sphygomanometer again toward transferring ".
In addition, exist owing to the excessive situation that does not measure pulse data Po of examining of being separated by in chest front electric sphygmomanometer 1 and the distance of heart.At this moment, carry out notices such as " please with sphygomanometer further near chest ".
Notifying for mobile electron sphygomanometer 1, so that electric sphygmomanometer 1 is in after the height identical with heart, turn back to S5, repeatedly carry out the processing of S5 to S9, until detect till the end of the 2nd mobile status.
The 2nd blood pressure measurement detection unit 245 that moves detecting unit 24 shown in Figure 2 is for example exported appropriate location detection signal Ms with the grade in 3 stages.Notification unit 4 uses notification units 42, with according to the suitable degree of heart height and different buzz or labellings notified this grade.And, if the 2nd mobile status finishes, then finish microwave and detect (S10).
Pressing speed (S11) is selected based on the Pulse Rate signal Mk that is calculated by Pulse Rate calculating part 244 in the pressurized conditions configuration part 371 of blood pressure measurement control part 37.
37 pairs of pressurized control sections 34 of blood pressure measurement control part control to drive force (forcing) pump 33, according to the mode that becomes the pressing speed of being set by pressurized conditions configuration part 371 bandage are pressurizeed, and beginning is based on the blood pressure measurement (S12) of measuring unit of blood pressure 3.
As mentioned above, measuring unit of blood pressure 3 is based on the pressure vibration waveform of the pressure signal So of pressure transducer 32 outputs during pressurizeing by blood pressure measurement control part 37 control pressurized control sections 34, calculate the blood pressure information Kj such as maximal blood pressure value, minimal blood pressure value, Pulse Rate, and show (S13) at display part 41.
In addition, can after the 2nd mobile status finishes (S8), not make the microwave of S10 in blood pressure measurement, continue to monitor appropriate location detection signal Ms with detecting end yet yet.In this situation, notify the supervision result of the appropriate location detection signal Ms in the blood pressure measurement with notification unit 4.For example, when electric sphygmomanometer 1 departs from from the appropriate location, notify this situation, interrupt blood pressure measurement and finish.
If blood pressure measurement finishes, then the blood pressure information memorizer 372 of blood pressure measurement control part 37 is stored blood pressure information and the appropriate location detection signal Ms such as maximal blood pressure values, minimal blood pressure value and Pulse Rate.
The measurement of the measured press operating part begins switch and finishes to measure (S10).At this moment, blood pressure information memorizer 372 also can be stored blood pressure information and the appropriate location detection signal Ms such as maximal blood pressure value, minimal blood pressure value and Pulse Rate.
