Detailed description of the invention

Fig. 1 illustrates the functional configuration of the blood pressure measuring system according to one embodiment.

Fig. 2 illustrates the operational instances of blood pressure measuring device shown in FIG. 1.

Fig. 3 illustrates the operational instances of blood pressure measuring device shown in FIG. 1.

Specific embodiment

Embodiment is described in detail below with reference to the accompanying drawings.Fig. 1 shows the functionality of blood pressure measuring system 1 according to the embodiment Configuration.Blood pressure measuring system 1 includes blood pressure measuring device 2 and cuff 3.

Blood pressure measuring device 2 is the device that the blood pressure of examinee 100 is measured using the cuff 3 for being attached to examinee 100, And including inflation mechanism 21, controller 22 and pulse acquisition unit 23.

Have the function of pumping function and valve by the inflation mechanism 21 that pipe 31 is connected to cuff 3.Pumping function is used for by will be empty Gas is transported to cuff 3 via pipe 31 and increases the interior pressure of cuff 3.Valve function be used for by pipe 31 be connected to outside air or with it is outer Portion's air disconnects.If pipe 31 is connected to outside air, the interior pressure drop of cuff 3 in the state that pumping function is not run It is low.

Controller 22 includes processor 221 and memory 222.As processor 221, CPU and MPU can be exemplified.Place Managing device 221 may include multiple cores.The example of memory 222 includes ROM and RAM.ROM can store various computer-readable fingers It enables.Processor 221 can specify at least part for the instruction stored in ROM that will be executed on RAM.Processor 221 can To cooperate to execute operation, as detailed below with RAM.

Pulse acquisition unit 23 with the cuff 3 for the body for being attached to examinee 100 by connecting and obtaining the arteries and veins of examinee 100 The sensor for rate of fighting is realized.Pulse acquisition unit 23 is configured as the signal that output corresponds to the pulse frequency of examinee 100.From pulse The pulse signal that acquisition unit 23 exports is input to controller 22.

Blood pressure measuring device 2 is configured as passing through the processing in controller 22 with the instruction being stored in memory 222 Device 221 executes and executes processing shown in Fig. 2.

Firstly, in step S1, blood pressure measuring device 2 activates the pumping function of inflation mechanism 21, thus with defined inflation speed Spend the interior pressure that (for example, 10mmHg/ seconds) increase cuff 3.

In step S2, blood pressure measuring device 2 obtains the pulse frequency of examinee 100 via pulse acquisition unit 23.Selectively, It can start the acquisition of pulse frequency before the charge operation of inflation mechanism 21.

Normally, non-to carry out using the information relevant with the beating of the artery of examinee to what is detected in cuff inflation Intrusive blood pressure measurement.To which more reliable survey can be obtained as the quantity of the pulsation detected during cuff inflation increases Measure result.However, if the pulse frequency of examinee is low, because the interior pressure of cuff reaches before the information for obtaining sufficient amount Limiting value is inflated, can occur in which the case where cannot obtaining desired Measurement reliability.

In view of above, in step S3, by the pulse frequency obtained via pulse acquisition unit 23 and defined pulse frequency (for example, 60bpm) it is compared.Defined pulse frequency is set as to be capable of providing the value of desired Measurement reliability.

If being lower than defined pulse frequency (S3:Y) via the pulse frequency that pulse acquisition unit 23 obtains, in step S4, blood Pressure measuring device 2 reduces the speed that inflation mechanism 21 inflates cuff 3.

For example, judgement cannot obtain desired Measurement reliability if the pulse frequency obtained is equal to 40bpm.Blood pressure is surveyed Amount device 2 determines new aeration speed according to following equation.

(new aeration speed)=(defined aeration speed) * (pulse frequency of acquisition)/(defined pulse frequency)

In the above-described example, new aeration speed is calculated as follows.

10 [mmHg/ seconds] * 40 [bpm]/60 [bpm]=6.7 [mmHg/ seconds]

Blood pressure measuring device 2 is with the so determining interior pressure for increasing cuff 3 for aeration speed 6.7mmHg/ seconds.

Using the above configuration, so that the quantity of the pulsation detected during inflation, which is equal to work as, has the tested of regulation pulse frequency Person is subjected to the quantity obtained when the measurement of defined aeration speed.Therefore, it can be avoided due to obtaining enough pulse informations Reach the fact that inflate limiting pressure before and restarts to measure.This makes it easier to keeping inflatable blood pressure measuring device Measurement is completed in a short time while 2 high measurement reliability.

In step S5, the aeration speed that blood pressure measuring device 2 is so changed by making inflation mechanism 21 increases cuff 3 Interior pressure and the blood pressure (at least one of systolic pressure and diastolic pressure) for determining examinee 100.Due to using inflatable blood pressure to survey It measures device and determines that the mode of blood pressure is known, so will not be described in detail further here.

If being not less than defined pulse frequency (S3:N) via the pulse frequency that pulse acquisition unit 23 obtains, in step S5, Blood pressure measuring device 2 determines examinee 100 and making inflation mechanism 21 increase with initial aeration speed the interior pressure of cuff 3 Blood pressure (at least one of systolic pressure and diastolic pressure).

Selectively, as shown in dashed line in figure 2, if be greater than via the pulse frequency that pulse acquisition unit 23 obtains defined Pulse frequency (S3:N；S6:Y), then in step S7, blood pressure measuring device 2 can be set the speed that inflation mechanism 21 inflates cuff 3 It is set to lower than initial velocity.

For example, controller 22 determines new aeration speed from the equations above if the pulse frequency obtained is 80bpm. That is, calculating new aeration speed as follows.

10 [mmHg/ seconds] * 80 [bpm]/60 [bpm]=13.3 [mmHg/ seconds]

Blood pressure measuring device 2 is with the so determining interior pressure for increasing cuff 3 for aeration speed 13.3mmHg/ seconds.

Although the increase by aeration speed shortens inflationtime, the quantity etc. of the pulsation detected during inflation It is same as being subjected to the quantity obtained when the measurement of defined aeration speed as the examinee with regulation pulse frequency.This makes it easier to Measurement is completed in a short time while keeping the high measurement reliability of inflatable blood pressure measuring device 2.

As shown in phantom in fig. 1, blood pressure measuring device 2 can be equipped with storage unit 24, and storage unit 24 can be by partly leading Body memory, hard disk drive etc. are realized.Storage unit 24 can be configured as the past measurement data of storage examinee 100.

Past measurement data may include the pulse frequency and pulse pressure for the examinee 100 being recorded in past blood pressure measurement At least one of.Pulse pressure is limited to the difference of systolic pressure and diastolic pressure.Alternatively, past measurement data may include stated number The average value of the pulse frequency of the examinee 100 recorded in the past blood pressure measurement of amount and the past blood pressure measurement of specified quantity At least one of the average value of pulse pressure of the examinee 100 of middle record.

As the instruction being stored in memory 222 in controller 22 is executed by processor 221, configured in this way blood pressure Measuring device 2 can execute processing shown in Fig. 3.

Firstly, blood pressure measuring device 2 obtains the past survey for the examinee 100 being stored in storage unit 24 in step S11 Measure data.

In step S12, blood pressure measuring device 2 determines inflation mechanism 21 to cuff 3 based on the past measurement data of acquisition The speed of inflation.To not need pulse acquisition unit 23 when determining aeration speed.

When past measurement data includes pulse frequency (or average value of the pulse frequency of storage in the past) of storage in the past, blood Pressure measuring device 2 determines aeration speed according to following equation.

(aeration speed)=(defined aeration speed) * (past pulse frequency)/(defined pulse frequency)

One example of defined aeration speed is 10mmHg/ seconds, and an example of defined pulse frequency is 60bpm.Defined aeration speed and defined pulse frequency are set so as to provide the value of desired Measurement reliability.

For example, calculating aeration speed as follows in the case where the past pulse frequency of acquisition is 40bpm.

10 [mmHg/ seconds] * 40 [bpm]/60 [bpm]=6.7 [mmHg]

The interior pressure that aeration speed 6.7mmHg/ second increases cuff 3 of the controller 22 so to determine.

By above-mentioned processing, so that the quantity of the pulsation detected during inflation, which is equal to work as, has the tested of regulation pulse frequency Person is subjected to the quantity obtained when the measurement of defined aeration speed.That is, in this example, according to the related to pulse frequency of examinee Trend setting cuff 3 appropriate aeration speed.Therefore, it can prevent due to equably to being known in advance with lower pulse frequency Examinee's the fact that use too high aeration speed and reach inflation limiting pressure before obtaining enough pulsation informations The case where.Furthermore, it is not necessary that the step of obtaining pulse frequency in real time by pulse acquisition unit 23.As a result, it is easier to keep inflating Measurement is completed in a short time while the high measurement reliability of formula blood pressure measuring device 2.

When past measurement data include track record pulse pressure (or track record pulse pressure average value) when, control Device 22 determines aeration speed according to following equation.

(aeration speed)=(defined aeration speed) * (past pulse pressure)/(defined pulse pressure)

One example of defined aeration speed is 10mmHg/ seconds, and an example of defined pulse pressure is 40mmHg.

As described above, pulse pressure is limited to the difference of systolic pressure and diastolic pressure in non-invasive blood pressure measurement.To, with Pulse pressure increases, and the quantity of the pulsation detected during inflation becomes larger, and therefore, so that measurement result is relatively reliable.However, working as When pulse pressure is low, because the interior pressure of cuff 3 reaches inflation limiting pressure before obtaining enough pulsation informations, it is possible that not It can obtain desired Measurement reliability.In consideration of it, defined pulse pressure is set so as to provide the value of desired Measurement reliability.

For example, calculating aeration speed as follows in the case where the past pulse pressure of acquisition is 30mmHg.

10 [mmHg/ seconds] * 30 [mmHg]/40 [mmHg]=7.5 [mmHg]

The interior pressure that aeration speed 7.5mmHg/ second increases cuff 3 of the controller 22 so to determine.

By above-mentioned processing, the quantity of the pulsation detected during inflation is equal to work as, and there is the examinee of regulation pulse pressure to be subjected to The quantity obtained when the measurement of defined aeration speed.That is, in this example, being set according to the trend relevant to pulse pressure of examinee Determine the appropriate aeration speed of cuff 3.It so, it is possible to prevent due to equably adopting to the examinee with lower pulse pressure is known in advance The case where with inflation limiting pressure is reached the fact that too high aeration speed and before obtaining enough pulsation informations.This Outside, the step of obtaining pulse frequency in real time by pulse acquisition unit 23 is not needed.As a result, it is easier to keep inflatable blood pressure measurement Measurement is completed in a short time while the high measurement reliability of device 2.

Past measurement data include track record pulse frequency (or track record pulse frequency average value) and In the case where pulse pressure (or in average value of the pulse pressure of track record) the two of track record, controller 22 is according to following equation Determine aeration speed.

(aeration speed)=(defined aeration speed) * [(past pulse frequency)/(defined pulse frequency)] * is [(past Pulse pressure)/(defined pulse pressure)]

For example, the past pulse frequency of acquisition be 40bpm and obtain past pulse pressure be 30mmHg in the case where, It is following to calculate aeration speed.

10 [mmHg/ seconds] * (40 [bpm]/60 [bpm]) * (30 [mmHg]/40 [mmHg])=5 [mmHg]

Blood pressure measuring device 2 is with the so determining interior pressure for increasing cuff 3 for aeration speed 5mmHg/ seconds.

In step S13, blood pressure measuring device 2 is by making inflation mechanism 21 increase cuff 3 with so determining aeration speed Interior pressure and determine the blood pressure (at least one of systolic pressure and diastolic pressure) of examinee 100.

As shown by the dotted line in fig. 3, blood pressure measuring device 2 can judge the past obtained from storage unit 24 in step S14 Measurement data whether meet defined condition (for example, from past time at time point of past measurement data is recorded Length is no longer than specified value).One example of the value of stipulated time length is 30 minutes.However, it is possible to according to examinee's 100 Situation or measurement environment suitably set stipulated time length.Other examples of the value of stipulated time length are a hour and one It.

If it is determined that the past measurement data obtained from storage unit 24 meets defined condition (S14:Y), then execute The step of stating for determining aeration speed (S12).

On the other hand, if it is determined that from storage unit 24 obtain past measurement data be unsatisfactory for defined condition (S14: N), then processing enters step S15, that is, processing shown in Fig. 2.Blood pressure measuring device 2 is obtained in step S2 via pulse acquisition unit 23 Pulse frequency is taken, is compared in the pulse frequency that step S3 will acquire with defined pulse frequency, and is filled according to comparison result determination The aeration speed that mechanism of qi structure 21 inflates cuff 3.

For example,, from newest measurement, long duration, newest measurement data include noise, blood pressure measuring device in the past 2 examinee's setting has changed in any situation changed with the capacity of cuff 3, the current trend of examinee (for example, Pulse frequency or pulse pressure) it may difference represented by the result with newest measurement.In this case, from the angle of Measurement reliability From the point of view of degree, be not suitable for using the aeration speed determining based on past measurement.

By above-mentioned processing, if the past measurement data obtained meet as defined in condition and be therefore it is reliable, The step of obtaining pulse frequency in real time by pulse acquisition unit 23 can then be omitted so as to shorten time of measuring.On the other hand, if The past measurement data obtained is unsatisfactory for defined condition and is not therefore reliably, then to obtain via pulse acquisition unit 23 Current (that is, correctly) pulse frequency, and determine based on the pulse frequency so obtained the aeration speed of cuff 3.Therefore, can Keep the Measurement reliability of blood pressure measuring device 2 high.

Above-described embodiment only contributes to understand an example of the disclosure, and can be without departing substantially from the basic of the disclosure The configuration of embodiment is appropriately modified or improved in the case where concept.

The inflation mechanism 21 and controller 22 of blood pressure measuring device 2 do not need always to be arranged in common shell.Controller 22 at least part function can be realized by the computing device for being connected to the computer of blood pressure measuring device 2.

The controller 22 and storage unit 24 of blood pressure measuring device 2 do not need always to be arranged in common shell.It is stored in Past measurement data in storage portion 24 can be stored in computer or service on the network that controller 22 can communicate Device.

Pulse acquisition unit 23 always do not need be arranged in blood pressure measuring device 2, and can be configured as can fill it is attached In the body of examinee.

For example, pressure sensor can be set in cuff 3 for use as pulse acquisition unit 23.In this case, it does not need Special device other than the cuff 3 of examinee to be attached to.To, the configuration of blood pressure measuring system 1 can not only be simplified, And the time for preparing measurement can be shortened.

As further alternative solution, sensor for measuring electrocardiogram can be used, for measuring arterial blood oxygen At least one of the sensor of saturation degree and invasive blood pressure measuring device are used as pulse acquisition unit 23.In this case, it controls Device 22 processed is based on signal acquisition examinee 100 corresponding with the pulse frequency exported from least one of the above sensor and device Pulse frequency.Due to using the pulse frequency relevant information for obtaining the physiologic information of other types, so can obtain can By the higher information relevant to pulse frequency of property, and with cuff 3 to fill attached state unrelated.From multiple sensors and/or device It, can be for example, by being compared and further increasing the essence of pulse frequency relevant information in the case where obtaining pulse frequency relevant information Degree.
