Beginning flow process shown in Figure 5 under the situation of having pushed on and off switch 41A.In addition, for the purpose of simplifying the description, in the following description, suppose to select rechargeable battery 51 to be used as power supply.
At first, select the user's begin to measure ID (step S2) by the user.CPU100 with the ID placeholder record selected in internal storage.
At this, judge that by CPU100 selected ID is whether identical with ID corresponding to the determination data of up-to-date (last time) minute, and preserve its result.For example, only under the situation identical, will be used to represent be made as " 1 " with mensuration person's sign of up-to-date mensuration person's homogeneity with up-to-date mensuration person.

Suppose when the number of times display process of proceeding to measure, to have imported the indication of measuring beginning by the user.So, the current magnitude of voltage placeholder record of the rechargeable battery 51 that calculating part 104 will obtain from voltage detection department 56 internal storage, the magnitude of voltage Vs (step S6) the when mensuration that is used as this begins.
Then, carry out the blood pressure determination processing by measuring control part 106.Specifically, at first, measure control part 106 and begin pump 33 is driven, the pressure of air bag 21 is risen gradually (pressurization) (step S8).In this example, because the switching part 58 of power control circuit 53 has been selected rechargeable battery 51, therefore be stored in the drive source that electric power in the rechargeable battery 51 becomes pump 33.
When the cuff pressure reaches the prescribed level (for example 180mmHg) that is used to measure blood pressure, measure control part 106 pump 33 is stopped, slowly opening buttoned-up air bleeding valve 34, the air of air bag 21 is discharged gradually.Thus, cuff is pressed and reduce (step S100) gradually.
In addition, in the present embodiment, persistent pressure is till the cuff pressure reaches prescribed level.But, also can infer maximal blood pressure, and persistent pressure is till reach the maximal blood pressure+setting (for example 40mmHg) of inferring according to the pulse wave information that in pressurization, obtains.
In addition, in the present embodiment, calculate blood pressure, but also can calculate blood pressure based on the pulse wave information that in pressure process, obtains based on the pulse wave information that in decompression process, obtains.
Then, measure control part 106 pressure value and the arteries and veins umber of beats that measurement result promptly calculates in step S12 is presented at (step S14) on the display part 40.
Then, the current magnitude of voltage placeholder record of the rechargeable battery 51 that calculating part 104 will obtain from voltage detection department 56 is used as this and measures magnitude of voltage Ve (step S16) when finishing internal storage.
At last, measuring control part 106 is stored in measurement result in the measurement result memory area in the memorizer 39 (step S18).Specifically, with the corresponding related ground of ID storing measurement value, magnitude of voltage Vs, the Ve of placeholder record.And then, preferably, will be used for determining the battery ID of the battery selected in this mensuration, store with magnitude of voltage Vs, Ve are corresponding relatedly.
More than, the release of sphygomanometer 1 (deenergization).
In the present embodiment, the moment that the demonstration of measurement result finishes is " measure when finishing and (measure the back) ", but is not limited to this.For example, can be the moment, the moment that decompression (step S10) finishes, the perhaps moment of blood pressure calculating (step S12) end that pressurization (step S8) finishes.
＜about the data structure example 〉
Fig. 6 is the figure of data structure example of the measurement result memory area 390 of expression this utility model embodiment.
With reference to Fig. 6, when measuring at every turn, in measurement result memory area 390 with the record (record) be the storing measurement data MDj of unit (j=1,2 ..., n).Measurement result memory area 390 also can be the predefined zone in the memorizer 39.
Fig. 7 is the figure of data structure example of each determination data MDj of expression this utility model embodiment.
With reference to Fig. 7, each determination data MDj comprises: the data of expression minute; The data of expression ID; The expression measured value is the data of maximal blood pressure (SBP), minimal blood pressure (DBP) and pulse wave number (PLS); The data of expression battery ID; The data of magnitude of voltage Vs when beginning is measured in expression; The data of the magnitude of voltage Ve when finishing are measured in expression.Minute is for example for having pushed the time of measuring the moment of switch 41B.
In addition, in the present embodiment, survey magnitude of voltage Vs, the Ve of periodic consumption data before and after promptly measuring at every turn and be also contained in the determination data, but be not limited to this.If set up the corresponding related consumption data that stores, then be not limited to such storage mode with ID and minute.
Perhaps, also can memory area be set according to each ID, thus the data beyond the memory area storage ID of the ID of correspondence.
＜number of times display process〉about measuring
The number of times display process that can measure among the step S4 of Fig. 5 is elaborated with reference to Fig. 8 and Fig. 9.In addition, in the step S2 of Fig. 5, suppose mensuration person sign 1 the situation of being made as is described.
Fig. 8 is the flow chart of the number of times display process that can measure of expression this utility model embodiment.Fig. 9 is the detection time diagram constantly that is illustrated in the voltage that uses in this utility model embodiment when calculating the number of times that can measure.
In addition, in Fig. 9, only show the particular moment magnitude of voltage, and the variation track of the voltage of not shown reality.
With reference to Fig. 8, calculating part 104 is read magnitude of voltage Vs, the Ve (step S102) of selected user's last time mensuration front and back from measurement result memory area 390.Specifically, for example, at first from the determination data of the battery ID of the battery that contains the ID among the step S2 of Fig. 5, selected and current selection, retrieve the determination data of up-to-date minute.Then, read magnitude of voltage Vs, the Ve that comprises in the determination data that is retrieved.
The magnitude of voltage of (t1) when as shown in Figure 9, the magnitude of voltage of (t0) when magnitude of voltage Vs represents that last mensuration begins, magnitude of voltage Ve represent that last mensuration finishes.
Then, calculating part 104 calculates the last voltage consumption amount VA that measures and is used as once consumption (step S104).Specifically, the magnitude of voltage Vs that deducts when measuring beginning by the magnitude of voltage Ve when measure finishing calculates voltage consumption amount VA.
Then, calculating part 104 detects the current voltage Vcr (step S 106) of the rechargeable battery 51 that obtains from voltage detection department 56.As shown in Figure 9, in current (the time t3) in this moment is between given period, be meant between this given period from this energized (time t2) measure to input till the indication of beginning during.
Then, calculating part 104 calculates amount of recovery VB (step S108).Magnitude of voltage Ve when finishing by deduct last mensuration from current magnitude of voltage Vcr calculates amount of recovery VB.
In memorizer 39, store the not enough threshold value of electric weight in advance at each battery.Calculating part 104 is by reading the not enough threshold value of the electric weight corresponding with selected battery from memorizer 39, use calculates the number of times that can measure with the kind corresponding threshold of battery.
When calculating the times N that can measure, CPU100 shows the number of times (step S114) that can measure on display part 40.Thus, the user can grasp the number of times that can measure of current time.In addition, under the situation that the times N that can measure is Duoed than specific number of times (for example 20 times), CPU100 also can report every specific times.
Then, CPU100 judges whether the user has imported the indication (step S116) of measuring beginning.Repeat the processing of step S106～step S114, till the indication of input mensuration beginning ("No" in step S116).
When having imported the indication of measuring beginning ("Yes" in step S116), handle being back to mastery routine.
In addition, pushed under the situation of storage switch 41C processing (determination data display process) that also can other programs of executed in parallel user after the energized and before beginning to measure.The determination data display process can realize by known method.
Like this, in the execution of determination data display process, also carry out the number of times display process that to measure, therefore when the determination data that shows in the past, also current voltage is monitored the number of times that calculating and report can be measured.Therefore, the user can know the up-to-date number of times that can measure all the time.
In Fig. 8 and Fig. 9, as mentioned above, show the example of the situation that is provided with mensuration person's sign, and under the situation that mensuration person's sign is not set, calculating part 104 for example calculates the number of times that can measure as follows.In addition, calculating part 104 for example judged before or after step S102 whether mensuration person's sign is 1.
Be masked as mensuration person under 0 the situation, calculating part 104 does not carry out the processing of step S108 (calculating of VB) and step S110 (sum operation of VA+VB).Therefore, replace the processing of step S112, calculating part 104 calculates the times N that can measure by the voltage consumption amount VA during remaining effective voltage value (current magnitude of voltage Vcr-threshold value Vth) was measured divided by the last time.
Perhaps, be masked as mensuration person under 0 the situation, replace step S110, calculating part 104 can calculate also that voltage consumption amount VA in last the mensuration adds predetermined value and value, be used as falling quantity of voltages VC#.In the case, replace step S112, calculating part 104 is by divided by falling quantity of voltages VC#, calculating remaining effective voltage value (current magnitude of voltage Vcr-threshold value Vth) times N that can measure and get final product.
＜about the demonstration example of the number of times that can measure 〉
Figure 10 is the figure of the demonstration example of the number of times that can measure of expression.That is, in Figure 10, show an example that in the step S114 of Fig. 8, is presented at the picture on the display part 40.
In (A) of Figure 10, the demonstration example when showing the remaining number of times that can measure and for example being 100 times.In (B) of Figure 10, the demonstration example when showing the remaining number of times that can measure and for example being 50 times.In (C) of Figure 10, the demonstration example when showing the remaining number of times that can measure and for example being 30 times.
As shown in figure 10, in the present embodiment, the number of times that can measure with numeric representation, and show the icon of the surplus that is used to represent battery.
In addition, the display packing of the information of the number of times that can measure is not limited to numerical value and shows, for example also can wait with sign to show.
In addition, in the present embodiment, report the number of times that to measure by showing.But, be not limited to demonstration, for example, also the mode of oscillation (pattern) of the sound that can send by buzzer 44 or the mode of vibration of motor (pump drive circuit 36) are reported.
The effect of＜embodiment 〉
As mentioned above,, obtain the slippage of measuring the voltage of the zero hour from the last time, can obtain user's voltage consumption tendency thus according to each user by present embodiment.And the slippage by calculating user's voltage can accurately calculate the number of times that can measure with respect to the ratio of residue effective voltage value (magnitude of voltage from current voltage to electric weight till the not enough threshold value).
That is to say, in the present embodiment, do not calculate the number of times that to measure based on the flash-over characteristic of battery.Therefore, can irrespectively calculate the correct number of times that can measure with the individual diversity of battery or the kind of battery.
In addition, because the thickness of arm is different because of the user, so the driving time of pump is according to the user and difference.Its result, the consumption of once measuring required voltage is according to the user and difference.Its result, even use the battery of same capability and identical type, measuring number of times also can be different.The driving time that pump is described with reference to Figure 11 is to measuring the influence that number of times brings.
Figure 11 is the different figure of expression owing to the different voltage-number of times characteristics that cause of thickness of the arm of person to be measured, and wherein, this voltage-number of times characteristic is represented the relation between magnitude of voltage and the mensuration number of times.
In (A) of Figure 11, show the typical case of voltage-number of times characteristic of the arm user thicker than standard.In (B) of Figure 11, show the typical case of voltage-number of times characteristic of the arm user thinner than standard.
With reference to (A), (B) of Figure 11, even begin to measure from moment of identical voltage V0, because the thick user's of arm pump driving time is long, it measures number of times also still less.
In the present embodiment, not to utilize the threshold value of fixed voltage to calculate the number of times that to measure, and be to use corresponding user's's (person to be measured) consumption once, therefore can eliminate the number of times error of bringing because of the difference of the thickness of user's arm.
In addition, under the situation till being pressurized to maximal blood pressure+setting, also the difference because of maximal blood pressure causes pump driving time difference.Also can eliminate the number of times error of bringing because of the difference of user's maximal blood pressure in the case.
That is to say,,, also can report out the most appropriate number of times that can measure corresponding (that is, the number of times that can measure may be according to the user and difference) with selected user even the value of the voltage of selected battery is identical by present embodiment
In addition, even the user is not stipulated (not using the situation of ID), so long as home-use sphygomanometer, the same user of just most of mensuration yet.Therefore, in the case, also by using consumption once in the past just can report the correct number of times that can measure.
In addition, by present embodiment, can also use the amount of recovery of measuring the voltage of the finish time from the last time.Therefore, when non-mensuration, promptly only set pattern or show under the situation of determination data in the past, also monitor voltage value termly, thus can calculate and upgrade the number of times that can measure.The time that shows on LCD is according to the user and difference, but by so carrying out the regular supervision of magnitude of voltage, all the time can be to the high value of user prompt reliability.In addition, its result can improve availability.
In addition, according to ambient temperature, the ratio of battery consumption is different.That is, according to ambient temperature, the flash-over characteristic of battery is different.In the present embodiment, owing to, calculate the number of times that to measure, therefore can reduce because the deviation of the number of times that difference caused of ambient temperature by detecting the slippage of actual voltage.
As mentioned above, by present embodiment, the user can grasp the number of times that accurate residue can be measured.Its result can not occur in the situation of measuring power shortage in the way.
In addition, the user can prepare new aneroid battery 52 in advance or rechargeable battery 51 is charged etc. according to the number of times that can measure.
In addition, under the situation of rechargeable battery 51, the user can charge after using surplus fully, therefore can give full play to the performance of rechargeable battery 51.That is, can prolong the life-span of rechargeable battery 51.
