The specific embodiment
Below, with reference to accompanying drawing, the preferred forms of electric sphygmomanometer of the present invention is elaborated.In addition, in the explanation and accompanying drawing of following embodiment, identical formation is added same-sign, and repeat specification is omitted.
Fig. 1 is that the integral body of the electric sphygmomanometer of expression embodiment 1 of the present invention constitutes block diagram.As shown in Figure 1, electric sphygmomanometer comprises: cuff 1, pressure detect mechanism 2, pressing mechanism 3, the mechanism of decompressor 4, indication mechanism 5, operating mechanism 6 and microcomputer (being designated hereinafter simply as microcomputer) 7.Cuff 1 detects mechanism 2, pressing mechanism 3 and the mechanism of decompressor 4 through conduit 8 and pressure and is connected.
Pressure detects the pressure that mechanism 2 is detected in the cuff 1.Pressure detects mechanism 2, is made up of for example pressure transducer.Pressing mechanism 3 pressurizes to cuff 1 according to the output signal of microcomputer 7.Pressing mechanism 3 is by the pump formation of for example fluids such as air (being designated hereinafter simply as air etc.) being delivered to cuff 1.
The mechanism of decompressor 4 reduces the pressure in the cuff 1 according to the output signal of microcomputer 7.The mechanism of decompressor 4 for example is made up of air bleeding valve, and this air bleeding valve is with dead slow speed and discharges hastily such as the air in the cuff 1.This air bleeding valve is opened when blood pressure determination finishes according to the output signal of microcomputer 7 fully, makes rapid decompression in the cuff 1.In addition, the mechanism of decompressor 4 also can constitute and comprise: make the deflated dead slow speed air bleeding valve of dead slow speeds such as air in the cuff 1; With carry out deflated rapidly air bleeding valve rapidly.
Maximal blood pressure value and minimal blood pressure value that indication mechanism 5 shows by microcomputer 7 decisions.Indication mechanism 5 shows that by for example LCDs with to this LCDs the controlling organization of control constitutes.Indication mechanism 5 also can constitute display pulse number and time.
Various buttons of operating by user when operating mechanism 6 comprises blood pressure determination and switch etc.For example be provided with: the double mensuration of doing the power button use begins button; Be used for importing the ID button of user identifier; Be used for setting the switch of pressurization value; Be used for preserving the memorizer button of measuring the result etc.
Microcomputer 7 is through carrying out the blood pressure determination program, realizes pressurized control mechanism 11, decompression controlling organization 12, pressure value determination means 13, Pulse Rate calculates mechanism 14 and pulse wave detects mechanism 15.Pressurized control mechanism 11 detects the force value in the cuff 1 that mechanism 2 detects according to pressure, and the pump that constitutes pressing mechanism 3 is carried out drive controlling.For example in the process of cuff pressurization, if the pressure in the cuff 1 reaches authorized pressure, pressurized control mechanism 11 just makes pump quit work.
Pulse wave detects mechanism 15, and when cuff 1 dead slow speed reduced pressure, detected pressures detected the pulse wave composition that mechanism 2 comprises in the output signal.Pulse Rate is calculated mechanism 14, and the output signal that detects mechanism 15 according to pulse wave is calculated Pulse Rate.Pressure value determination means 13 detects the pulse wave composition that mechanism 15 detects according to pulse wave, and employing for example based on the blood pressure decision algorithm of well-known oscillographic method, decides maximal blood pressure value and minimal blood pressure value.The pressure value of decision is presented on the indication mechanism 5.In addition, pressure value determination means 13 is opened in order to make air bleeding valve behind the decision pressure value fully, sends to decompression controlling organization 12 and measures the notice that finishes.
Here, though do not do particular determination, air bleeding valve for example can be driven by the driving signal that pulse amplitude modulation is crossed.In this case, the controlling value that is used for controlling exhaust valve opening is represented by the digital value corresponding to pulse amplitude.Decompression controlling organization 12 changes the dutycycle of the driving signal of air bleeding valve through changing this digital value, controls the aperture of air bleeding valve.
Though do not do particular determination, for example the air bleeding valve of the mechanism of decompressor 4 can be: its aperture of digital value that controlling value is big is more little, and its aperture of digital value that controlling value is little is big more.Therefore, if controlling value is big, the decompression rate of cuff 1 is just little; If controlling value is less, the decompression rate of cuff 1 is just big.Be that air bleeding valve is opened fully, cuff 1 aerofluxus rapidly under zero the situation in for example controlling value.
Fig. 2 is the formation block diagram of expression decompression controlling organization 12.As shown in Figure 2, decompression controlling organization 12 possesses: decompression rate is calculated mechanism 21, the decompression rate deviation is calculated mechanism 22, controlling value correction table selection mechanism 23, controlling value correction table 24, controlling value correction determination means 25 and controlling value correction mechanism 26.
Decompression rate is calculated mechanism 21, in cuff 1 decompression process, calculates its decompression rate.Decompression rate for example detects force value in the cuff 1 that mechanism 2 detects to pressure to carry out differential and obtains.The decompression rate deviation is calculated mechanism 22, calculates the deviation (velocity deviation) that decompression rate is calculated the decompression rate distance objective decompression rate that mechanism 21 calculates.Velocity deviation deducts the target decompression rate from current decompression rate and obtains.
Relation between controlling value correction table 24 regulation Pulse Rates and velocity deviation and the controlling value correction.Controlling value correction table 24 is recorded and narrated in the blood pressure determination program.Fig. 3～Fig. 5 is the sketch map of a routine controlling value correction table.Though do not do particular determination,,, be provided with 3 controlling value correction table 24a, 24b, 24c here according to the scope of Pulse Rate like Fig. 3～shown in Figure 5.
Controlling value correction table A24a shown in Figure 3, be for example Pulse Rate greater than the table of selecting under 60 times/minute situation.Controlling value correction table B24b shown in Figure 4 be for example Pulse Rate greater than 40 times/minute and be the table of selecting under 60 times/minute following situation.Controlling value correction table C24c shown in Figure 5 is that for example Pulse Rate is the table of selecting under the situation below 40 times/minute.If velocity deviation is Δ V.
As shown in Figure 3, in controlling value correction table A24a, for example, under [Δ V＜-2.0] and [2.0≤Δ V＜-1.5] situation, the correction of controlling value is respectively-4 and-3.In addition, under [1.5＜Δ V≤2.0] and [2.0＜Δ V] situation, the correction of controlling value is respectively+3 and+4.
That is to say that the controlling value correction is defined as: the decompression rate of cuff 1 is more little than target decompression rate, and exhaust valve opening is strengthened, and strengthens decompression rate, makes controlling value littler.Otherwise the controlling value correction is defined as: the decompression rate of cuff 1 is more big than target decompression rate, and exhaust valve opening is reduced, and reduces decompression rate, makes controlling value bigger.Controlling value correction table B24b and controlling value correction table C24c also are same.
In addition, as shown in Figure 4, in controlling value correction table B24b, under the situation of for example [Δ V＜-2.0], the correction of controlling value is-5.In addition, as shown in Figure 5, in controlling value correction table C24c, under the situation of for example [Δ V＜-2.0], the correction of controlling value is-6.Like this, the controlling value correction just is defined as: even if velocity deviation Δ V is identical, also be that Pulse Rate is more little, make controlling value reduce more.It the reasons are as follows.
As stated, the control of the correction of decompression controlling organization 12 pairs of controlling values and 12 pairs of mechanisms of decompressor 4 of decompression controlling organization, pulse wave detect mechanism 15 detect pulse wave after, detect at each pulse wave and to implement when mechanism 15 detects pulse wave.Therefore, when Pulse Rate was big, controlling value will shorten to next interval before changing after changing.So; Even if exhaust valve opening controlling value after changing to change to next value before during be fixed; Decompression rate can excessively not deviate from the speed of hope yet, because also significantly be not lower than when hoping speed at decompression rate, next controlling value change has regularly been arrived.
Otherwise, when Pulse Rate hour, controlling value after changing to next time interval before changing will prolong.Therefore, controlling value after changing until change to next value during, decompression rate just may be lower than significantly hopes speed.Want to reduce controlling value after changing until change to next value during the reduction of decompression rate, can to controlling value after changing until change to next value during the part that grows estimate, exhaust valve opening is set slightly bigly.Therefore, revise in such a way: Pulse Rate is more little, controlling value is more little, and strengthens exhaust valve opening thus.
In addition, in controlling value correction table A24a, controlling value correction table B24b and controlling value correction table C24c, the controlling value correction when velocity deviation Δ V is worth for other such as Fig. 3～shown in Figure 5, at this, do not enumerate.In addition, can be to the establishing method of the velocity deviation Δ V scope of the establishing method of the quantity of controlling value correction table 24, Pulse Rate scope, each table etc., carry out various changes.
Controlling value correction table selection mechanism 23 from above-mentioned 3 controlling value correction table A24a, controlling value correction table B24b and controlling value correction table C24c, is selected to calculate the corresponding table of Pulse Rate that mechanism 14 calculates with Pulse Rate.The controlling value correction table 24 that controlling value correction determination means 25 is selected with reference to controlling value correction table selection mechanism 23 is calculated the velocity deviation that mechanism 22 calculates according to the decompression rate deviation, determines the correction of above-mentioned controlling value.
Controlling value correction mechanism 26 is revised controlling value according to the correction of controlling value correction determination means 25 decisions.For example, controlling value correction mechanism 26 is used as new controlling value with the correction addition of current controlling value and 25 decisions of controlling value correction mechanism.Then, controlling value correction mechanism 26 is controlled the exhaust valve opening of the mechanism of decompressor 4 according to above-mentioned controlling value.When controlling value correction mechanism 26, receive when measuring end notification from pressure value determination means 13, can open air bleeding valve fully.
Fig. 6 is the flow chart that the decompression in the blood pressure determination step of electric sphygmomanometer of expression embodiment 1 of the present invention begins the back step.A succession of step shown in Figure 6 is after cuff 1 is pressurizeed, and cuff 1 internal pressure reaches that the time point of authorized pressure begins.As shown in Figure 6, when cuff 1 decompression beginning, at first be decompression controlling organization 12, read control initial value (step S1).This controls initial value, is recorded and narrated in the blood pressure determination program.Then, decompression controlling organization 12 is set at initial controlling value (step S2) with this control initial value.
Then, adopt well-known blood pressure decision algorithm to measure blood pressure (step S3).When cuff 1 decompression beginning, the air bleeding valve of the mechanism of decompressor 4 is depressurized controlling organization 12 and is set at the pairing aperture of controlling value (control initial value) that step S2 sets.This time point is followed by decompression beginning back, so maximal blood pressure value and the decision as yet of minimal blood pressure value at this moment.That is to say that blood pressure determination does not finish (step S4:No).
Therefore, decompression controlling organization 12 is carried out well-known decompression control algolithm, calculates the Pulse Rate that mechanism 14 calculates according to force value and Pulse Rate that pressure detects in the cuff 1 that mechanism 2 detects, and (step S5) controlled in the decompression of stating after carrying out.Return step S3 then, measure blood pressure.Repeated execution of steps S3～S5; After pressure value determination means 13 has determined maximal blood pressure value and minimal blood pressure value, just judge that blood pressure determination finishes (step S4:Yes), opens the air bleeding valve of the mechanism of decompressor 4 fully; Make cuff 1 aerofluxus rapidly, finish a series of reduced pressure treatment shown in Figure 6.
Fig. 7 is the flow chart of decompression controlled step of the electric sphygmomanometer of expression embodiment 1 of the present invention.When the step S5 of Fig. 6 begins to reduce pressure control treatment, at first, calculate mechanism 21 by decompression rate and calculate the decompression rate of cuff 1 (step S11).Then, calculate mechanism 22 by the decompression rate deviation and calculate velocity deviation Δ V (step S12).Then, calculate mechanism 14 by Pulse Rate and carry out the calculating of Pulse Rate, judge and whether can calculate Pulse Rate (step S13).
Under the situation that can calculate Pulse Rate (step S13:Yes), judge that by controlling value correction table selection mechanism 23 whether Pulse Rate is greater than 60 times/minute (step S14).If Pulse Rate greater than 60 times/minute (step S14:Yes), is just selected above-mentioned controlling value correction table A24a (step S15) by controlling value correction table selection mechanism 23.Can not calculate at step S13 under the situation of Pulse Rate (step S13:No), controlling value correction table A24a also can be selected (step S15).
On the other hand, if Pulse Rate less than 60 times/minute (step S14:No), just judges that by controlling value correction table selection mechanism 23 Pulse Rate is whether greater than 40 times/minute and be (step S16) below 60 times/minute.When Pulse Rate is in above-mentioned scope (step S16:Yes), just select above-mentioned controlling value correction table B24b (step S17) by controlling value correction table selection mechanism 23.In addition, if Pulse Rate is (step S16:No) below 40 times/minute, just select controlling value correction table C24c (step S18) by controlling value correction table selection mechanism 23.
Follow step S15, step S17 or step S18; The velocity deviation Δ V that 25 meetings of controlling value correction determination means are calculated according to step S12 reads control corresponding value correction (step S19) from the controlling value correction table 24 that step S15, step S17 or step S18 select.Then, the correction that controlling value correction mechanism 26 is read step S19 embodies on the current controlling value, as new controlling value (step S20).Then, finish a series of decompression control treatment shown in Figure 7.
To be an example be set at the 40 effect performance plots that carry out under the controlling value correction situation, the relation of express time and cuff 1 internal pressure with Pulse Rate to Fig. 8.In addition, in Fig. 8, " no controlling value is proofreaied and correct " only is meant and controls exhaust valve opening according to the decompression rate of cuff 1, do not revise according to Pulse Rate." there is controlling value to proofread and correct " and is meant, carry out the controlling value correction according to Pulse Rate according to flow chart shown in Figure 7.
Can be known by Fig. 8, not carry out under the situation of controlling value correction that decompression rate will be less than the target decompression rate, the decompression end needs for a long time.Relative therewith, compare with situation about not revising, under the situation of carrying out the controlling value correction, decompression will be more point-blank and according to target decompression rate carry out, reaching decompression within a short period of time and finishing pressure.
Fig. 9 is that the integral body of the electric sphygmomanometer of expression embodiment 2 of the present invention constitutes block diagram.As shown in Figure 9, electric sphygmomanometer comprises: cuff 1, pressure detect mechanism 2, pressing mechanism 3, exhaust gear 9, indication mechanism 5, operating mechanism 6 and microcomputer (being designated hereinafter simply as microcomputer) 7 rapidly.Cuff 1 detects mechanism 2, pressing mechanism 3 through conduit 8 and pressure and is connected with exhaust gear 9 rapidly.Embodiment 2 is in cuff 1 pressurization, to measure blood pressure.
Exhaust gear 9 rapidly, when blood pressure determination finishes, according to the output signal of microcomputer 10, with the aerofluxuss rapidly such as air in the cuff 1.Exhaust gear 9 for example is made up of air bleeding valve rapidly.It is identical with embodiment 1 that pressure detects mechanism 2, pressing mechanism 3, indication mechanism 5 and operating mechanism 6.Microcomputer 10 realizes that through carrying out the blood pressure determination program pressurized control mechanism 11, pressure value determination means 13, Pulse Rate are calculated mechanism 14, pulse wave detects mechanism 15 and aerofluxus controlling organization 16.
Pulse wave detects mechanism 15 when cuff 1 pressurization, detects pressure and detects pulse wave composition contained in the output signal of mechanism 2.It is identical with embodiment 1 that Pulse Rate is calculated mechanism 14.Pressure value determination means 13 is identical with embodiment 1, decision maximal blood pressure value and minimal blood pressure value, and to the 11 output pressurization halt instructions of pressurized control mechanism, simultaneously, to the standard-sized sheet instruction of aerofluxus controlling organization 16 output air bleeding valves.Aerofluxus controlling organization 16 receive the standard-sized sheet instruction from blood pressure determination means 13 after, is opened air bleeding valve fully.
Pressurized control mechanism 11 detects the pressing speed of the pressure in the cuff 1 that mechanism 2 detects according to pressure, and the pump that constitutes pressing mechanism 3 is carried out drive controlling, makes its pressing speed near the target pressing speed.When carrying out above-mentioned control, the Pulse Rate and sleeve pressing speed with pressure that mechanism 14 calculates calculated according to Pulse Rate by pressurized control mechanism 11, revises being used for the controlling value of control pump drive amount, makes this pressing speed further near the target pressing speed.Though pressure detects the pressure detecting in 2 pairs of cufves of mechanism 1; At any time carry out according to the sampling period; But be used to control the value (cuff 1 in force value) of decompression rate, can use pulse wave to detect the force value before mechanism 15 detects after the pulse wave composition, particularly pulse wave will rise at once.This be because, use the nonoverlapping force value of pulse wave composition, can correctly detect the pressure in the cuff 1.In addition; The correction of the controlling value of 11 pairs of pressing mechanisms 3 of pressurized control mechanism (pump) and to the control of pressing mechanism 3; Be to detect after mechanism 15 detects the pulse wave composition at pulse wave; Synchronous with pulse wave, in the specified time limit that one of the trough of pulse wave or crest have been located, carry out the special provision of this embodiment: the pulse wave after the crest value of pulse wave detects carries out when descending.This is for fear of following situation: if when the crest of the trough of pulse wave or pulse wave, revise the controlling value of pressing mechanism 3; Control pressing mechanism 3; Will be on the crest of the trough of pulse wave or pulse wave; Thereby the pressing speed of controlling cuff 1 because of the pump drive amount of control pressing mechanism 3 produces noise, influences the trough value of pulse wave or the crest value of pulse wave, even influences the decision of pressure value.Therefore, the correction of 11 pairs of controlling values of above-mentioned pressurized control mechanism and to the control of pressing mechanism 3 detects at each pulse wave and to implement when pulse waves detect in mechanism 15.In addition, when blood pressure determination finishes, if after pressurized control mechanism 11 receives the pressurization halt instruction from blood pressure determination means 13, stop driving to pump.
Here, do not do particular determination, but pump can be for example by the pulse amplitude modulation drive.In this case, be used for the controlling value of drive amount of control pump, represent by digital value corresponding to pulse amplitude.Pressurized control mechanism 11 changes the dutycycle of pump drive signal, the drive amount of coming control pump through changing this digital value.
Though do not do particular determination, for example can be that the digital value of controlling value is bigger, drive amount force feed amount increases as far as pump; The digital value of controlling value is more little, drive amount reduces.Therefore, if controlling value is big, it is big that the pressing speed of cuff 1 will become; If controlling value is little, the pressing speed of cuff 1 will diminish.
Figure 10 is the block diagram of the structure of expression pressurized control mechanism.Shown in figure 10, pressurized control mechanism 11 possesses: controlling value correction table selection mechanism 23, controlling value correction table 24, controlling value correction determination means 25, controlling value correction mechanism 26, pressing speed calculates mechanism 27 and the pressing speed deviation is calculated mechanism 28.
Pressing speed is calculated mechanism 27 and in cuff 1 pressure process, is calculated its pressing speed.Pressing speed for example is to carry out differential and obtain through pressure being detected force value in the cuff 1 that mechanism 2 detects.The pressing speed deviation is calculated mechanism 28, calculates the deviation (velocity deviation) that pressing speed is calculated the pressing speed distance objective pressing speed that mechanism 27 calculates.Velocity deviation deducts the target pressing speed from current pressing speed and obtains.
Controlling value correction table 24 is identical with embodiment 1.Just, embodiment 1 is that the controlling value of air bleeding valve is revised, and embodiment 2 is that the controlling value of pump is revised, so the correction of controlling value is different with embodiment 1.Figure 11～Figure 13 is the sketch map of a routine controlling value correction table.Though do not do particular determination,,, be provided with 3 controlling value correction table 24d, 24e, 24f here according to the scope setting of Pulse Rate like Figure 11～shown in Figure 13.
Controlling value correction table D24d shown in Figure 11 be for example Pulse Rate greater than the table of selecting under 60 times/minute situation.Controlling value correction table E24e shown in Figure 12 be for example Pulse Rate greater than 40 times/minute and be the table of selecting under 60 times/minute following situation.Controlling value correction table F24f shown in Figure 13 is that for example Pulse Rate is the table of selecting under 40 times/minute following situation.
Shown in figure 11, in controlling value correction table D24d, for example under the situation of [Δ V＜-2.0] and [2.0≤Δ V＜-1.5], the correction of controlling value is respectively+4 and+3.In addition, under [1.5＜Δ V≤2.0] and [2.0＜Δ V] situation, the correction of controlling value is respectively-3 and-4.
That is to say that the controlling value correction is defined as: the pressing speed of cuff 1 is more little than target pressing speed, and the drive amount of pump is strengthened, and strengthens pressing speed, makes controlling value bigger.Otherwise the controlling value correction is defined as: the pressing speed of cuff 1 is more big than target pressing speed, and the drive amount of pump is reduced, and reduces pressing speed, makes controlling value littler.Controlling value correction table E24e and controlling value correction table F24f also are same.
In addition, shown in figure 12, in controlling value correction table E24e, for example under [Δ V＜-2.0] situation, the correction of controlling value is+5.In addition, shown in figure 13, in controlling value correction table F24f, for example under [Δ V＜-2.0] situation, the correction of controlling value is+6.Like this, the correction of controlling value just is defined as: even if velocity deviation Δ V is identical, also be Pulse Rate more little, increase controlling value more.It the reasons are as follows.
When continuing cuff 1 pressurization when the controlling value that does not change pump, its pressing speed will reduce.As stated, the control of 11 pairs of pressing mechanisms 3 of the correction of 11 pairs of controlling values of pressurized control mechanism and pressurized control mechanism, pulse wave detect mechanism 15 detect pulse wave after, detect at each pulse wave and to implement when mechanism 15 detects pulse wave.Therefore, when Pulse Rate was big, controlling value arrived the next time of interval weak point before changing after changing.So; Even if the drive amount of pump controlling value after changing to change to next value before during be fixed; Pressing speed can excessively not deviate from the speed of hope yet, because when pressing speed did not have also that too the width of cloth is not lower than the speed of hope, next controlling value change had regularly been arrived.
Otherwise, when Pulse Rate hour, controlling value after changing to next time interval before changing will prolong.Therefore, controlling value after changing until change to next value during, pressing speed will be lower than hopes speed.Want to reduce controlling value after changing until change to next value during the reduction of pressing speed, can to controlling value after changing until change to next value during the part that grows estimate, the drive amount of pump is set slightly bigly.Therefore, revise in such a way: Pulse Rate is more little, and controlling value is big more, and strengthens the drive amount of pump thus.In addition, in controlling value correction table D24d, controlling value correction table E24e and controlling value correction table F24f, the controlling value correction when velocity deviation Δ V is worth for other such as Figure 11～shown in Figure 13, do not enumerate at this.
Controlling value correction table selection mechanism 23 from above-mentioned 3 controlling value correction table D24d, controlling value correction table E24e and controlling value correction table F24f, selects Pulse Rate to calculate the pairing table of Pulse Rate that mechanism 14 calculates.Controlling value correction determination means 25 with reference to the controlling value correction table 24 that controlling value correction selection mechanism 23 is selected, is calculated the velocity deviation that mechanism 28 calculates according to the pressing speed deviation, determines above-mentioned controlling value correction.
Controlling value correction mechanism 26 is identical with embodiment 1, after controlling value is revised, with it as new controlling value.Then, controlling value correction mechanism 26 is according to this controlling value, and the drive amount of the pump of pressing mechanism 3 is controlled.In addition, controlling value correction mechanism 26 receive the pressurization halt instruction from pressure value determination means 13 after, stops the driving to pump.
Figure 14 is the flow chart that the pressurization in the blood pressure determination step of electric sphygmomanometer of expression embodiment 2 of the present invention begins the back step.Shown in figure 14, after the cuff 1 pressurization beginning, at first, pressurized control mechanism 11 reads control initial value (step S31).This control initial value is recorded and narrated in the blood pressure determination program.Then, pressurized control mechanism 11 should control initial value and be set at initial controlling value (step S32).
Next, adopt well-known blood pressure decision algorithm, measure blood pressure (step S33).During cuff 1 pressurization beginning, the pressurized controlling organization 11 of the pump of pressing mechanism 3 is set the air etc. of the corresponding amount of controlling value (control initial value) of force feed and step S32 setting for.After this time point begins followed by pressurization, so maximal blood pressure value and the decision as yet of minimal blood pressure value at this moment.So blood pressure determination does not finish (step S34:No).
Therefore, pressurized control mechanism 11 carries out well-known pressurized control algorithm, calculates the Pulse Rate that mechanism 14 calculates, the pressurized control of stating after carrying out (step S35) according to force value and Pulse Rate that pressure detects in the cuff 1 that mechanism 2 detects.Then, return step S33, measure blood pressure.Repeated execution of steps S33～S35; If pressure value determination means 13 determines maximal blood pressure value and minimal blood pressure value, just be judged as blood pressure determination and finish (step S34:Yes), stop the pump of pressing mechanism 3; Simultaneously; Open the air bleeding valve of exhaust gear 9 rapidly, make cuff 1 aerofluxus rapidly, finish a series of pressurized treatments shown in Figure 14.
Figure 15 is the flow chart of pressurized control step of the electric sphygmomanometer of expression embodiment 2 of the present invention.After the step S35 at Figure 14 begins the pressurized control processing, at first, calculate mechanism 27 by pressing speed and calculate the pressing speed of cuff 1 (step S41).Then, calculate mechanism 28, calculate velocity deviation Δ V (step S42) by the pressing speed deviation.Calculate mechanism 14 by Pulse Rate then and calculate Pulse Rate, can judgement calculate Pulse Rate (step S43).
Under the situation that can calculate Pulse Rate (step S43:Yes), judge that by controlling value correction table selection mechanism 23 whether Pulse Rate is greater than 60 times/minute (step S44).If Pulse Rate greater than 60 times/minute (step S44:Yes), is just selected above-mentioned controlling value correction table D24d (step S45) by controlling value correction table selection mechanism 23.Under the situation that can not calculate Pulse Rate (step S43:No), also select controlling value correction table D24d (step S45).
On the other hand, if Pulse Rate less than 60 times/timesharing (step S44:No), just judges that by controlling value correction table selection mechanism 23 Pulse Rate is whether greater than 40 times/minute and be (step S46) below 60 times/minute.When Pulse Rate is in above-mentioned scope (step S46:Yes), select above-mentioned controlling value correction table E24e (step S47) by controlling value correction table selection mechanism 23.In addition, if Pulse Rate is (step S46:No) below 40 times/minute, just select controlling value correction table F24f (step S48) by controlling value correction table selection mechanism 23.
Follow step S45, step S47 or step S48; Controlling value correction determination means 25; Velocity deviation Δ V according to step S42 calculates reads control corresponding value correction (step S49) from the controlling value correction table of selecting at step S45, step S47 or step S48 24.Then, controlling value correction mechanism 26, the correction that step S49 is read embodies on the current controlling value, as new controlling value (step S50).Then, finishing a series of pressurized control shown in Figure 15 handles.
As stated, according to embodiment 1, according to the velocity deviation of the decompression rate of Pulse Rate and cuff 1, the controlling value of the air bleeding valve of the control mechanism of decompressor 4 obtains revising, and makes decompression rate near the target decompression rate.In addition, according to embodiment 2, according to the velocity deviation of the pressing speed of Pulse Rate and cuff 1, the controlling value of the pump of control pressing mechanism 3 obtains revising, and makes pressing speed near the target pressing speed.Therefore, even Pulse Rate is little, also can produce following effect: when changing cuff 1 internal pressure, measure blood pressure with the decompression rate of hope or pressing speed.In addition, can also produce following effect:, also can under the situation that does not prolong minute, measure blood pressure even Pulse Rate is little.
For above content, the invention is not restricted to above-mentioned embodiment, can carry out various changes.For example, the explanation of embodiment and the numerical value described in the accompanying drawing are instances, and the present invention is not limited to these numerical value.In addition; Though the example of the drive that to be air bleeding valve crossed by pulse amplitude modulation of embodiment 1 explanation; The example of the drive that to be pump crossed by pulse amplitude modulation of embodiment 2 explanation drives air bleeding valve and pump but also can constitute with other type of drive.
