The metrical information that current time is obtained according to the sensor in ambulatory blood pressure measuring instrument, can also measure number of users by external equipment
According to ambulatory blood pressure measuring instrument obtains the user data of measurement from external equipment, to determine the current pose of user.
Optionally, the current metrical information of acquisition can be the current pose of user, and the current pose of user includes position of lying
Posture, standing and sitting gesture and athletic posture.The current appearance of user is determined according to the current metrical information that ambulatory blood pressure measuring instrument obtains
State determines that its current pose is pose state of lying when measuring user and being in lying status, when measure user be in sitting posture or
It when stance, determines that its current pose is standing and sitting gesture, when measuring user just during exercise, determines that current pose is athletic posture.
Measurement posture when can measure blood pressure according to user as a result, selects measurement pattern.
Optionally, the current metrical information of acquisition may be present period, which includes period and night in the daytime
Between the period.Ambulatory blood pressure measuring instrument obtains time for currently measuring, to determine period that user currently measures, when determination is current
Section determines its present period as the period in the daytime, when determining present period at night, determines that present period is night in day time
Period.The time of measuring that blood pressure can be measured according to user as a result, selects measurement pattern.
Step 12, according to the current metrical information, select the current blood pressure of corresponding measurement pattern measurement user, obtain
Preliminary measurement results.
When the current metrical information obtained in step 11 is the current pose of user, judge that user is presently at movement
Posture, is in pose state of lying, and or be in standing and sitting gesture, the specific posture being according to user, selection and its posture

The heart rate of amount is 70, can set normal range (NR) as 62-78.Normal cardiac rate of the different user under rest state is different, then its
Preset range is different.
If S143, the heart rate at current time are within a preset range, determine that the preliminary measurement results are calibration result.
If the heart rate at user's current time is within a preset range, show that user's Current heart rate is normal, the blood pressure of measurement is
For the blood pressure under normal condition, using preliminary measurement results as the calibration result of user's ambulatory blood pressure.
If S144, the heart rate at current time within a preset range, do not correct the preliminary measurement results, determine correction result
For calibration result.
If the heart rate at user's current time within a preset range, does not show that user's Current heart rate is abnormal, heart rate is too fast
Or blood pressure can be all influenced slowly excessively, at this point, the blood pressure of measurement cannot represent the true blood pressure of user.It is right according to the occurrence of heart rate
Preliminary measurement results are modified, using modified result as the calibration result of user's ambulatory blood pressure.
Optionally, modified calibration result is marked, so that medical staff or user know the mark value and non-real
Magnitude is surveyed, when further calculating, chooses whether to avoid using the mark value using non-genuine measured value according to the actual situation
Calculating causes calculated result inaccurate.
Optionally, current measurement can be repaired according to the measurement result of the adjacent periods of current measurement cycle
Just, for example, using the average value of the measurement result in a upper period for current measurement cycle and the measurement result in next period as working as
The measurement result of preceding measurement period.
Optionally, the measurement result currently measured can be modified according to the first predetermined coefficient, the first default system
Number can be preset when initializing ambulatory blood pressure measuring instrument by medical staff or user.
Optionally, when the current state of user is not normal condition when measuring blood pressure, shorten measurement period, carry out multiple
Measurement.It is repaired further according to the second predetermined coefficient to the multiple measurement results taken multiple measurements after measurement period are shortened
Just, for example, using the average value of multiple measurement results as modified measurement result, which is set in advance by user
It is fixed.
It is, of course, also possible to be other possible correcting modes, user is in combination with practical application, according to the current state of user
A kind of mode is selected to be modified measurement result, the present embodiment is not especially limited.

Fig. 2 is a kind of implementation process schematic diagram of step 11 in embodiment illustrated in fig. 1, described current in the implementation
Metrical information is the current pose of user, and the current pose includes lie pose state, standing and sitting gesture and athletic posture.Such as Fig. 2 institute
Show, in the implementation of the present embodiment, obtain current metrical information specifically includes the following steps:
Step 201, the attitude parameter for obtaining current time.
Wherein, the attitude parameter includes angular speed, acceleration and magnetic data.Ambulatory blood pressure measuring instrument can pass through setting
Sensor inside it obtains angular speed, acceleration and the magnetic data of current time user, can also be obtained by external equipment
It takes.When the sensor by being provided at its inner portion obtains, the sensor can be attitude transducer.Attitude transducer is base
In the high-performance motion attitude measuring system of micro electro mechanical system (MEMS) technology, include the auxiliary such as gyroscope, accelerometer, electronic compass fortune
Dynamic sensor.Preferably, the gyroscope is three-axis gyroscope, and the accelerometer is three axis accelerometer, electronics sieve
Disk sensor be three axle electronic compass sensor, three-axis gyroscope, three axis accelerometer, three axle electronic compass sensor relative to
Two axis gyroscopes, two axis accelerometers, two axis electronic compass sensors, can be improved the precision of attitude parameter, so as to make
State survey meter of blood pressure is more accurate to the judgement of user's current pose.
Step 202 calibrates the attitude parameter.
After ambulatory blood pressure measuring instrument gets the attitude parameter at current time, pass through embedded low-power consumption arm processor point
Other angular velocity, acceleration and magnetic data are calibrated, and are modified to the parameter value for deviation occur, are avoided according to inaccuracy
There is error in user's attitude data that attitude parameter obtains, and determining user's current pose is caused to malfunction.
Step 203 obtains user's attitude data according to the attitude parameter after calibration.
Attitude parameter after calibration is subjected to athletic posture measurement by the sensing data algorithm based on quaternary number, in real time
The zero shift 3 d pose data indicated with quaternary number, Eulerian angles etc. are exported, three attitude datas of the zero shift are user's appearance
State data.
Step 204, the current pose that the user is determined according to the attitude data.
The user's attitude data obtained according to upper step, respectively with the posture number of lie pose state, standing and sitting gesture and athletic posture
According to comparing, the most matched posture of attitude data is determined as working as user in the pose state that will lie, standing and sitting gesture and athletic posture
Preceding posture.
Fig. 3 is another implementation process schematic diagram of step 11 in embodiment illustrated in fig. 1, described to work as in the implementation
Preceding metrical information is the current pose of user, and the current pose includes lie pose state, standing and sitting gesture and athletic posture.Such as Fig. 3
It is shown, in the implementation of the present embodiment, obtain current metrical information specifically includes the following steps:
Step 301, the acceleration for obtaining ambulatory blood pressure measuring instrument current time.
When ambulatory blood pressure measuring instrument determines the current posture of user, adding for current time ambulatory blood pressure measuring instrument is obtained first
Speed, the ambulatory blood pressure measuring instrument are carried by user, and therefore, the acceleration of the ambulatory blood pressure measuring instrument of acquisition is user's carrying
The acceleration at the specific position of ambulatory blood pressure measuring instrument, for example, ambulatory blood pressure measuring instrument is worn on the upside of elbow joint by user
When 1-2cm (centimetre), which is the acceleration of 1-2cm on the upside of elbow joint；Ambulatory blood pressure measuring instrument is worn on hand by user
When wrist, which is the acceleration of wrist.The acceleration at ambulatory blood pressure measuring instrument current time can specifically be existed by setting
Sensor inside ambulatory blood pressure measuring instrument obtains, and can also be obtained by external equipment.When the biography by being provided at its inner portion
When sensor obtains, optionally, the sensor is acceleration transducer, and the acceleration that acceleration transducer obtains is vector, packet
Size and Orientation is included, what size indicated is the physical quantity of the speed of ambulatory blood pressure measuring instrument current time velocity variations, direction table
What is shown is the direction of ambulatory blood pressure measuring instrument current time movement.Preferably, acceleration transducer is 3-axis acceleration sensor,
By the acceleration in measurement tri- reference axis of X, Y, Z, the acceleration at user's current time is obtained, thus according to current time
Acceleration determines the current pose of user.
Step 302, when the size of the acceleration at the current time be greater than or equal to the first preset threshold when, determine described in
The current pose of user is athletic posture.
When the size of the acceleration at the current time of acquisition is greater than or equal to the first preset threshold, show user currently just
It is moving, at this point, determining that the current pose of user is athletic posture.First preset threshold is preset by user.Optionally,
First preset threshold of setting is slightly over zero value, i.e. the size of acceleration is not zero, when current time acceleration it is big
When being less than first preset threshold and being greater than zero, although user is not at stationary posture at current time, it is similar to static appearance
State, the movement of user movement are not enough to influence measurement result.
Step 303, when the size of the acceleration at the current time be less than first preset threshold when, obtain dynamic blood
The acceleration of measuring instrument historical juncture is pressed, the historical juncture is that nearest apart from the current time and acceleration size is greater than
At the time of first preset threshold.
When the size of the acceleration at the current time of acquisition is less than the first preset threshold, show that user is currently at non-fortune
Dynamic posture, as lie pose state or standing and sitting gesture.To further determine that user is presently at lie pose state or standing and sitting gesture,
Ambulatory blood pressure measuring instrument obtains the acceleration of its historical juncture by searching for the acceleration that the moment before stores, wherein this is gone through
The history moment is at the time of illustrating that current time is nearest and size of its acceleration is greater than the first preset threshold.For example, when current
Carving is 23 points, and the size of acceleration at this time is 0, is met less than the first preset threshold, before obtaining at 23 points, meets distance simultaneously
It is 21:30, Yong Hu at the time of such as acquisition at the time of 23 times are most short and size of acceleration is greater than the first preset threshold
Between 21:30 to 23 points, the size of acceleration is consistently less than the first preset threshold, obtains the acceleration that the historical juncture is 21:30,
According to the instantaneous variation of acceleration, user is analyzed in 21:30, is to become standing and sitting gesture from other postures, still becomes position of lying
Posture, the step 304 specific as follows stated is to described in step 306.
Step 304 judges whether the direction of the acceleration of the historical juncture meets preset condition.
Ambulatory blood pressure measuring instrument gets nearest apart from current time and acceleration size and is greater than the first preset threshold
After the acceleration of historical juncture, judge whether the direction of the acceleration of historical juncture meets preset condition, the preset condition is by curing
Shield personnel or user preset.Optionally, preset condition is the direction of acceleration in the XOZ plane of space coordinates XYZ
Projection and X-axis positive direction angle be greater than the second preset threshold.Specific deterministic process are as follows: judge space coordinates XYZ
In, whether the angle that acceleration Z axis is biased to X-axis forward direction is greater than the second preset threshold, and acceleration is projected to space coordinates XYZ
XOZ plane on, judge whether the projection and the angle of X-axis positive direction are greater than the second preset threshold, when the angle be greater than second
When preset threshold, illustrate that user is just becoming pose state of lying from other postures in the historical juncture, otherwise, illustrates user in the history
Moment becomes standing and sitting gesture from other postures.
Optionally, the value of the second preset threshold is the value greater than 45 °.Preferably, in the present embodiment, the second preset threshold
It is 60 °.
If the direction of step 305, the acceleration of the historical juncture meets preset condition, the current appearance of the user is determined
State is pose state of lying.
Still with above-mentioned for example, when the direction of acceleration of the user in 21:30 is in the XOZ plane of space coordinates XYZ
On projection and the angle of positive direction of X-axis when being 70 °, be greater than 60 ° of the second preset threshold, meet preset condition, it is determined that use
Family becomes pose state of lying in 21:30, from other postures, due to user's acceleration between 21:30 to 23 points size always
Less than the first preset threshold, that is to say, that user's posture between 21:30 to 23 points does not change, accordingly, determines that user exists
At 23, posture is pose state of lying.
If the direction of step 306, the acceleration of the historical juncture is unsatisfactory for preset condition, determine that the user's is current
Posture is standing and sitting gesture.
Still with above-mentioned for example, when the direction of acceleration of the user in 21:30 is in the XOZ plane of space coordinates XYZ
On projection and the angle of positive direction of X-axis when being 30 °, less than 60 ° of the second preset threshold, be unsatisfactory for preset condition, it is determined that
User becomes standing and sitting gesture in 21:30, from other postures, since the size of user's acceleration between 21:30 to 23 points begins
Eventually less than the first preset threshold, that is to say, that user's posture between 21:30 to 23 points does not change, accordingly, determines user
At 23, posture is standing and sitting gesture.
Fig. 4 is a kind of implementation process schematic diagram of step 12 in embodiment illustrated in fig. 1, which is in Fig. 2 or Fig. 3 institute
On the basis of showing embodiment, according to fig. 2 or embodiment illustrated in fig. 3 obtain current metrical information, select corresponding measurement pattern
The current blood pressure of user is measured, specifically, as shown in figure 4, according to the current metrical information, selection corresponds in the present embodiment
Measurement pattern measurement user current blood pressure specifically includes the following steps:
Step 401, when the current pose be athletic posture when, select descending manner measurement pattern measure working as the user
Preceding blood pressure.
When user measures ambulatory blood pressure under athletic posture, the corresponding descending manner measurement pattern measurement of athletic posture is selected
The current blood pressure of user, obtains preliminary measurement results.Specifically, descending manner measurement pattern, carries out cuff using air pump quick
Inflating pressure is at complete impatency state using inflation cuff compressing arteries, then slowly deflates, in cuff pressure
It during decline, acquires the pressure amplitude curve of artery and systolic pressure and diastolic pressure is extrapolated according to characteristic point, to obtain just
Walk measurement result.User just during exercise, using descending manner measurement pattern measure ambulatory blood pressure, avoid external interference to survey
Measure the influence of result, the accuracy that ensure that measurement result of maximum possible.
Optionally, when current pose is athletic posture, ambulatory blood pressure measuring instrument judges whether the athletic posture is violent
Athletic posture judges whether user's current kinetic is strenuous exercise.Specifically, the heart rate of user is obtained, when the heart rate is big
When third predetermined threshold value, determine that the athletic posture is strenuous exercise's posture, when the heart rate is default less than or equal to third
When threshold value, determine that the athletic posture is non-strenuous exercise's posture, label measurement result is strenuous exercise's posture.Due to moving shadow
When ringing the blood pressure, especially strenuous exercise of user's measurement, the blood pressure of measurement can reach 160-170 or even 180, it is clear that at this moment survey
The pressure value of amount and the actual blood pressure of non-user cannot be used to determine whether user suffers from hypertension.According to user strenuous exercise
When heart rate be greater than normal value feature carry out strenuous exercise's posture judgement.Ambulatory blood pressure measuring instrument is obtained by sensor thereon
Family Current heart rate is taken, when heart rate third predetermined threshold value pre-set greater than user, shows that user's Current heart rate is greater than just
Often heart rate when movement, at this point, determining that the current athletic posture of user is strenuous exercise's posture.When heart rate is less than or equal to user
When pre-set third predetermined threshold value, show heart rate of user's Current heart rate no more than proper motion when, at this point, determining user
Current athletic posture is non-strenuous exercise's posture.When ambulatory blood pressure measuring instrument determines that athletic posture is strenuous exercise's posture,
User's blood pressure is measured using descending manner measurement pattern, and measurement result is labeled as strenuous exercise's posture, so as to according to measurement
When 24 hours pressure values calculate one day mean blood pressure of user, the pressure value measured under strenuous exercise is screened and is removed, or
It is calculated again after being modified to the pressure value measured under strenuous exercise.
Step 402, when the current pose be lie pose state when, select pulse wave measurement mode measure working as the user
Preceding blood pressure.
When user measures ambulatory blood pressure under pose state of lying, the corresponding pulse wave measurement mode measurement of pose state of lying is selected
The current blood pressure of user, obtains preliminary measurement results.Specifically, pulse wave is heartthrob (vibration) along arteries and blood
It flows to periphery spread and is formed, pulse wave measurement mode is to substitute spot measurement with multimetering, utilizes systolic pressure and diastole
Inner link and changing rule near pressure point between each point, measurement obtain the blood pressure of user.Since pulse wave measurement mode is surveyed
There is no the mistake that medical staff's hearing, visual debility generate when taking blood pressure, fault caused by manual operation is avoided.Meanwhile
, it can be achieved that noiseless blood pressure measurement when pulse wave measurement mode measures blood pressure, realize user lie rest when noiseless survey
It takes blood pressure.Also, user in lie pose state when, greatly all in sleep state, without deliberately remaining stationary state, dynamic blood
Press measuring instrument smaller by extraneous interference, it is poor using the ambulatory blood pressure measuring instrument anti-interference of pulse wave measurement mode to avoid
Defect, further, using pulse wave measurement mode measure when to user without constriction, it is same what is improved the user experience
When, also substantially increase the accuracy of nighttime blood pressures measurement.
Step 403, when the current pose be standing and sitting gesture when, select ascending manner measurement pattern measure working as the user
Preceding blood pressure.
When user measures ambulatory blood pressure under standing and sitting gesture, the corresponding ascending manner measurement pattern measurement of standing and sitting gesture is selected
