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,, omit repeat specification to the additional same-sign of same structure.
Fig. 1 is that the integral body of the electric sphygmomanometer of expression embodiments of the present invention 1 constitutes block diagram.As shown in Figure 1, electric sphygmomanometer comprises: cuff 1, pressure detecting mechanism 2, pressing mechanism 3, the mechanism of decompressor 4, indication mechanism 5, operating mechanism 6 and microcomputer (hereinafter referred to as microcomputer) 7.Cuff 1 is connected by conduit 8 with pressure detecting mechanism 2, pressing mechanism 3 and the mechanism of decompressor 4.
The pressure that pressure detecting mechanism 2 is detected in the cuff 1.Pressure detecting mechanism 2 is made of for example pressure transducer.Pressing mechanism 3 pressurizes to cuff 1 according to the output signal of microcomputer 7.Pressing mechanism 3 is made of the pump 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 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 fully according to the output signal of microcomputer 7, makes rapid decompression in the cuff 1.In addition, the mechanism of decompressor 4 also can constitute: have the deflated dead slow speed air bleeding valve of dead slow speeds such as air that makes 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 preservation button of preserving measurement result etc.
Microcomputer 7 is realized pressurized control mechanism 11, decompression controlling organization 12, pressure value determination means 13, control initial value guiding mechanism 14 and pulse wave testing agency 15 by carrying out the blood pressure determination program.Pressurized control mechanism 11, the force value according in the pressure detecting mechanism 2 detected cufves 1 drives control to the pump that constitutes pressing mechanism 3.For example in the process of cuff 1 pressurization, if the pressure in the cuff 1 reaches authorized pressure, pressurized control mechanism 11 just makes pump quit work.
Here, though do not do special qualification, air bleeding valve is for example by the pulse amplitude modulation drive.In this case, be used at the control initial value of when beginning decompression control exhaust valve opening and be used for the controlling value of in decompression process control exhaust valve opening, represent by digital value corresponding to pulse amplitude.Decompression controlling organization 12 changes the dutycycle of the driving signal of air bleeding valve by changing this digital value, controls the aperture of air bleeding valve.
Though do not do special qualification, for example the air bleeding valve of the mechanism of decompressor 4 is: its aperture of digital value that controlling value is bigger is more little, and less its aperture of digital value of controlling value is big more.Therefore, if controlling value is bigger, the decompression rate of cuff 1 just diminishes; If controlling value is less, it is big that the decompression rate of cuff 1 just becomes.Be that air bleeding valve is opened fully, cuff 1 aerofluxus rapidly under zero the situation in for example controlling value.
Control initial value guiding mechanism 14 according to the force value in the detected cuff 1 of pressure detecting mechanism 2, is adjusted the control initial value in cuff 1 dead slow speed decompression process.The control initial value that is upgraded by this adjustment, the control initial value when decompression begins when being used as blood pressure determination next time uses.That is to say, in the electric sphygmomanometer of embodiment, the control initial value that decompression controlling organization 12 upgrades during according to last blood pressure determination, when the decompression of this blood pressure determination begins, the control exhaust valve opening.
When pulse wave testing agency 15 reduces pressure in cuff 1 dead slow speed, detect the pulse wave composition that pressure detecting mechanism 2 comprises in output signal.Pressure value determination means 13, according to the pulse wave composition that pulse wave testing agency 15 is detected, employing for example based on the blood pressure decision algorithm of known oscillometry, decides maximal blood pressure value and minimal blood pressure value.The pressure value that is determined is presented on the indication mechanism 5.In addition, pressure value determination means 13 is opened fully in order to make air bleeding valve when the decision pressure value, sends to decompression controlling organization 12 and measures the notice that finishes.
Fig. 2 is the formation block diagram of expression control initial value guiding mechanism.As shown in Figure 2, control initial value guiding mechanism 14 comprises: the elapsed time decision mechanism 21; Begin the decompression rate of process during the stipulated time from decompression and calculate mechanism's (be designated hereinafter simply as decompression rate and calculate mechanism) 22; The decompression rate deviation is calculated mechanism 23; Begin the pressure slippage of process during the stipulated time from decompression and calculate mechanism's (be designated hereinafter simply as the pressure slippage and calculate mechanism) 24; Control initial value correction determination means 25; Control initial value correction table 26; Control initial value correction mechanism 27; With control initial value storing mechanism 28.
Elapsed time decision mechanism 21, carry out beginning to pass through the stipulated time judgement of (for example 1 second or 2 seconds) from cuff 1 decompression.Elapsed time deducts the decompression zero hour with current time and obtains.Particularly be exactly for example to record and narrate following steps in the reduced pressure treatment subprogram of blood pressure determination program: when the specific subprogram in the reduced pressure treatment subprogram was carried out the processing of stipulated number by microcomputer 7, the judgement decompression beginning back stipulated time is mistake.Handle these steps by microcomputer 7, realize elapsed time decision mechanism 21.
Like this, judging with software processes under the situation in elapsed time that be exactly the moment that the reduced pressure treatment subprogram is begun the zero hour of reducing pressure, just zero.Current time is exactly that moment after stipulated number is handled has been carried out in specific subprogram in 7 pairs of reduced pressure treatment subprograms of microcomputer.In addition, the elapsed time after the decompression beginning is exactly that specific subprogram in 7 pairs of reduced pressure treatment subprograms of microcomputer is carried out stipulated number and handled the needed time.
Here, the reduced pressure treatment subprogram is to be used for program that cuff 1 is reduced pressure, by microcomputer 7 as execution after being used for the pressurized treatments end of subroutine of the program of cuff 1 pressurization.In addition, judge that the elapsed time can not realize by recording and narrating said procedure yet, but enumerator or timer etc. are set on electric sphygmomanometer, come Measuring Time with them.
Decompression rate is calculated mechanism 22, and decision mechanism 21 is judged to be the time point that begins to pass through the stipulated time from decompression in the elapsed time, calculates the decompression rate of the cuff 1 of this time point.Decompression rate for example carries out differential to the force value in the pressure detecting transposition 2 detected cufves 1 and obtains.The decompression rate deviation is calculated mechanism 23, calculates the deviation (velocity deviation) that decompression rate is calculated the decompression rate distance objective decompression rate that mechanism 22 calculates.Velocity deviation is to deduct the target decompression rate and obtain with current decompression rate.
The pressure slippage is calculated mechanism 24, and decision mechanism 21 is judged to be the time point that begins to pass through the stipulated time from decompression in the elapsed time, calculates the slippage that the pressure in the cuff 1 of this time point begins from decompression.The pressure slippage, the force value that the force value during with the decompression beginning in the cuff 1 deducts in the current cuff 1 is obtained.Control initial value correction table 26 fixing speed deviations, pressure slippage and target decompression rate, and the relation between the control initial value correction.Control initial value correction table 26 is recorded and narrated in the blood pressure determination program.
Fig. 3 represents to control an example of initial value correction table.Here, establish velocity deviation, pressure slippage and target decompression rate, be respectively Δ V[mmHg/sec], P[mmHg] and R[mmHg/sec].In control initial value correction table 26 shown in Figure 3, for example, Δ V less than-4 situation under, when [P ≦ 0.5 * R], control initial value correction be-5; When [0.5 * R＜P ≦ R], the correction of control initial value is-4.In addition, Δ V greater than 4 situation under, when [R＜P ≦ 1.5 * R], control initial value correction be+4; When [1.5 * R＜P], control initial value correction be+5.
That is to say that 26 pairs of corrections of control initial value correction table have been carried out following regulation: under the decompression rate of cuff 1 situation littler,, strengthen decompression rate, will further reduce controlling value in order to strengthen exhaust valve opening than target decompression rate; Otherwise, under the decompression rate of cuff 1 situation bigger,, reduce decompression rate in order to reduce exhaust valve opening than target decompression rate, will further strengthen controlling value.In addition, also stipulate correction: under the less situation of pressure slippage, further reduce controlling value; Otherwise, under the bigger situation of pressure slippage, further strengthen controlling value.In addition, the control initial value correction when Δ V is worth for other is not enumerated at this as shown in Figure 3.
Control initial value correction determination means 25 is with reference to control initial value correction tables 26, and decision and decompression rate deviation are calculated the correction that velocity deviation that mechanism 23 calculates and pressure slippage are calculated the corresponding control initial value of pressure slippage that mechanism 24 calculates.Control initial value correction mechanism 27 is revised the control initial value according to the correction of control initial value correction determination means 25 decisions.For example, control initial value correction mechanism 27 is read the control initial value that is kept in the control initial value storing mechanism 28, with this control initial value and by the correction addition of controlling 25 decisions of initial value correction determination means.
Control initial value storing mechanism 28 is preserved the control initial value of being revised by control initial value correction mechanism 27.Control initial value storing mechanism 28 is made of the memorizer in the microcomputer 7.Decompression controlling organization 12 when decompression begins when blood pressure determination next time, is read the control initial value from control initial value storing mechanism 28.
Here, to when where determining to control the initial value correction, consider that two aspects of velocity deviation and pressure slippage describe.When carrying out blood pressure determination in cuff 1 decompression process,, preferably under stable decompression rate, measure in order to detect pulse wave conscientiously.For example, both can measure with fixed decompression rate by control bit, also can be on one side change the target decompression rate according to the pressure of cuff 1, on one side the control decompression.And, in order to finish blood pressure determination at short notice as far as possible, need in the short as far as possible time, reach the decompression rate that is suitable for blood pressure determination in cuff 1 decompression beginning back, i.e. the target decompression rate.In addition, in order after cuff 1 decompression beginning, to detect pulse wave immediately, need as far as possible under the higher state of cuff 1 internal pressure, reach the target decompression rate.Therefore, need to consider velocity deviation and two aspects of pressure slippage.
This case inventors are through discovering repeatedly: the exhaust valve opening of cuff 1 when the decompression beginning has a suitable scope.When exhaust valve opening during less than this proper range, reaching the target decompression rate just needs the long period, so minute can be elongated.And on the other hand, when exhaust valve opening was excessive, the back to back pressure slippage in decompression beginning back will be excessive, is unsuitable for blood pressure determination.In this case inventors' experiment, in the combination of specific cuff and air bleeding valve, when exhaust valve opening is 30～40% left and right sides when cuff 1 decompression beginning,, reached the target decompression rate with the shortest time and with the state of pressure slippage minimum.
Fig. 4 is the flow chart of the step after the decompression beginning in the blood pressure determination step of electric sphygmomanometer of expression embodiments of the present invention 1.A succession of step shown in Figure 4 is to begin on the time point that cuff 1 pressurization and cuff 1 internal pressure is reached authorized pressure.As shown in Figure 4, when the decompression of cuff 1 began, at first, decompression controlling organization 12 read control initial value (step S1) from control initial value storing mechanism 28.Then, decompression controlling organization 12, the control initial value that will read from control initial value storing mechanism 28, the controlling value (step S2) the when decompression that is set at this begins.
Next, according to known blood pressure decision algorithm, 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 sets the corresponding aperture of setting with step S2 of controlling value (from controlling the control initial value that initial value storing mechanism 28 is read) for.Above-mentioned time point, decompression just just begins, and maximal blood pressure value and minimal blood pressure value be not decision (step S4:No) as yet.Therefore, decompression controlling organization 12 is carried out known decompression control algolithm, according to the control (step S5) of reducing pressure of the force value in the pressure detecting mechanism 2 detected cufves 1.
Next, control initial value guiding mechanism 14 judges whether the control initial value adjusts finish (step S6).If the adjustment of control initial value finishes (step S6:Yes), just return the blood pressure determination of step S3; If the control initial value is not adjusted (step S6:No) as yet, control initial value guiding mechanism 14 is just carried out control initial value adjustment described later and is handled (step S7), returns the blood pressure determination of step S3 then.Then, the blood pressure determination that continues determines (step S4:Yes) after maximal blood pressure value and the minimal blood pressure value by pressure value determination means 13, opens the air bleeding valve of the mechanism of decompressor 4 fully, makes cuff 1 aerofluxus rapidly, finishes a series of reduced pressure treatment shown in Figure 4.
Fig. 5 is the flow chart of control initial value set-up procedure of the electric sphygmomanometer of expression embodiments of the present invention 1.After the step S7 of Fig. 4 begins to control the initial value adjustment and handles, at first, the elapsed time decision mechanism 21, obtain the elapsed time (T) (step S11) after the cuff 1 decompression beginning, judge whether this elapsed time (T) reaches setting value (step S12).Here, in order to express when the elapsed time that begins from cuff 1 decompression reaches the stipulated time, can carry out the processing of back, just be expressed as by step S11 and step S12 and judge the elapsed time, but in fact, as mentioned above, the specific subprogram in 7 pairs of reduced pressure treatment subprograms of microcontroller has been carried out on the time point of processing of stipulated number, and the elapsed time (T) has just reached setting value.
Do not reach in the elapsed time (T) that cuff 1 decompression has begun under the situation of setting value (step S12:No), finish a series of control initial value adjustment processing shown in Figure 5.Reach in the elapsed time (T) that cuff 1 decompression has begun under the situation of setting value (step S12:Yes), calculate mechanism 22, calculate the decompression rate (step S13) of cuff 1 decompression when having begun to pass through the stipulated time with decompression rate.Then, calculate mechanism 23, calculate velocity deviation (Δ V) (step S14) with the decompression rate deviation.In addition, calculate mechanism 24, calculate cuff 1 decompression and begun the pressure slippage (P) (step S15) of process during the stipulated time with the pressure slippage.
Then, control initial value correction determination means 25, velocity deviation (Δ V) and pressure slippage (P) according to calculating at step S14 and step S15 read control corresponding initial value correction (step S16) from controlling initial value correction table 26.Then, control initial value correction mechanism 27, the correction that step S16 is read embodies on the current control initial value, again as control initial value (step S17).Control initial value correction mechanism 27 is kept at above-mentioned new control initial value in the control initial value storing mechanism 28 (step S18).Then, a series of control initial value adjustment processing shown in Figure 5 just is through with.
Fig. 6 is the performance plot of the revised effect of expression one example control initial value.It shows relation between the velocity deviation of pressure in the cuff 1 and decompression rate and the relation between time and cuff 1 internal pressure respectively.In addition, in Fig. 6, " the 1st time " be meant, the decompression of the cuff 1 that the control initial value carries out during numerical value (design load) when dispatching from the factory, and " the 11st time " is meant, after carrying out the correction of 10 control initial values, carries out the decompression of cuff 1.
As shown in Figure 6, by controlling the correction of initial value, the pressure of cuff 1 can reduce to be similar to collinear state in the short period after the cuff 1 decompression beginning.
Fig. 7 is the formation block diagram of control initial value guiding mechanism of the electric sphygmomanometer of expression embodiments of the present invention 2.As shown in Figure 7, control initial value guiding mechanism 34 comprises: decompression rate is calculated mechanism 41, decompression rate deviation and is calculated the pressure slippage that elapsed time till mechanism 42, target decompression rate arrive decision mechanism 43, target decompression rate and arrive calculates till mechanism (below, abbreviate as elapsed time calculate mechanism) 44, target decompression rate arrive and calculate mechanism's (be designated hereinafter simply as the pressure slippage and calculate mechanism) 45, control initial value correction determination means 46, control initial value correction mechanism 47 and control initial value storing mechanism 48.
Decompression rate is calculated mechanism 41, according to the force value in the detected cuff 1 of pressure detecting mechanism 2, calculates the decompression rate of cuff 1 in cuff 1 decompression process.The decompression rate deviation is calculated mechanism 42, and to calculate mechanism 23 identical with the decompression rate deviation of embodiment 1.The target decompression rate arrives decision mechanism 43, judges whether the decompression rate of cuff 1 reaches the target decompression rate.For example, the target decompression rate arrives decision mechanism 43, and the absolute value of velocity deviation of calculating the decompression rate that mechanism 42 calculates in the decompression rate deviation judges that the decompression rate of cuff 1 has reached the target decompression rate during less than predefined permissible value.
Elapsed time is calculated mechanism 44, calculate until the target decompression rate arrive decision mechanism 43 be judged to be reach the target decompression rate, from elapsed time that decompression begins.For example, the elapsed time is calculated mechanism 44, and is identical with the elapsed time decision mechanism 21 of embodiment 1, by software processes, calculates the elapsed time.The pressure slippage is calculated mechanism 45, and to calculate mechanism 24 same with the pressure slippage of embodiment 1, calculates to reach decision mechanism 43 until the target decompression rate and be judged to be and reach the slippage that the pressure target decompression rate, in cuff 1 begins to reduce pressure.
Control initial value correction determination means 46 is calculated elapsed time and the pressure slippage that mechanism 44 calculates according to the elapsed time and is calculated the pressure slippage that mechanism 45 calculates, the correction of relational expression decision control initial value according to the rules.This relational expression is not particularly limited.If but cuff 1 decompression has been begun to be made as T and P respectively until elapsed time that reaches the target decompression rate and pressure slippage, and establish α and the coefficient of β for setting according to the target decompression rate, so for example available [α * P-β * T] represents.
This relational expression and factor alpha and β are recorded and narrated in the blood pressure determination program.For example, when the target decompression rate was 10mmHg/sec, α and β were respectively 0.1 and 1.0.Control initial value correction mechanism 47 and control initial value storing mechanism 48, the control initial value correction mechanism 27 with embodiment 1 is identical with control initial value storing mechanism 28 respectively.Step after decompression in the voltage determination step of the electric sphygmomanometer of embodiment 2 begins is identical with flow chart shown in Figure 4.So omit explanation.
Fig. 8 is the flow chart of control initial value set-up procedure of the electric sphygmomanometer of expression embodiments of the present invention 2.After the step S7 of Fig. 4 begins to control initial value adjustment processing, at first, calculate mechanism 41 with decompression rate and calculate the decompression rate of cuff 1 (step S21).Then, calculate the velocity deviation (Δ V) (step S22) that decompression rate is calculated by mechanism 42 with the decompression rate deviation.Next, arrive decision mechanism 43 with the target decompression rate, whether the absolute value of judging above-mentioned velocity deviation (Δ V) is below permissible value (step S23).
