Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

In the measuring process, the blood pressure measuring device needs to ensure that the blood pressure measuring position of the measured user is flush with the heart height of the measured user, so that the accuracy of the measured blood pressure can be ensured. However, since it is necessary to ensure that the blood pressure measurement position of the user to be measured is flush with the heart height of the user to be measured, there are also inconveniences to the measurement process, and more importantly, it is difficult for the user to be measured to keep the blood pressure measurement position flush with the heart height for a long time for continuous blood pressure measurement, which may cause inaccuracy in blood pressure measurement.

Currently, the inventors have found that there are techniques available for measuring the height difference between the blood pressure measurement location and the heart. For example, a "wired connection" between the blood pressure measurement location and the heart flush location, such as by measuring the hydraulic pressure inside the rubber tube to calculate the height difference; for example, the external positioning device is used to position the blood pressure measurement position and the heart position, and then the height difference between the two positions is calculated. However, the implementation of the above method is complicated, and brings inconvenience to the use process of the user.

In order to solve the problems, the inventor finds out through long-term research and proposes the blood pressure measurement method, the device, the electronic equipment and the storage medium, and the correction is performed on the blood pressure obtained by the measurement unit by setting the correction unit for representing the heart part of the user to be measured and the measurement unit for representing the blood pressure measurement part of the user to be measured, so that the posture limitation of blood pressure measurement can be avoided, and the convenience and the accuracy of blood pressure measurement are improved. The specific blood pressure measurement method is described in detail in the following examples.

Referring to fig. 1, fig. 1 is a flow chart illustrating a blood pressure measurement method according to an embodiment of the present application. The method is used for correcting the blood pressure obtained by the measurement unit by setting the correction unit for representing the heart part of the user to be measured and the measurement unit for representing the blood pressure measurement part of the user to be measured, so that the gesture limitation of blood pressure measurement can be avoided, and the convenience and accuracy of blood pressure measurement are improved. In a specific embodiment, the blood pressure measurement method is applied to the blood pressure measurement device 300 shown in fig. 10 and the electronic apparatus 100 (e.g., measurement unit) provided with the blood pressure measurement device 300 (fig. 11). It will be appreciated that the measurement unit and the correction unit may have a physical connection, for example may be combined as one device, or the correction unit may be a separate element or device from the measurement unit. The specific flow of the present embodiment will be described below by taking an electronic device as an example, and it will be understood that the electronic device applied in the present embodiment may include a blood pressure measuring device, a smart bracelet, a smart watch, etc., which are not limited herein. The following will describe the flow chart shown in fig. 1 in detail, and the blood pressure measurement method specifically may include the following steps:

Step S110: and under the condition that the measuring unit measures the blood pressure of the user to be measured, acquiring an initial measuring result.

In the present embodiment, in the case where the measurement unit performs blood pressure measurement of a user to be measured, an initial measurement result obtained by the measurement unit is obtained. The measurement unit may be disposed at a blood pressure measurement location of the user to be measured.

In some embodiments, the measurement unit may detect whether the measurement unit is disposed at a blood pressure measurement site of a user to be measured, wherein the blood pressure measurement site of the user to be measured may include: upper arm, finger, neck, wrist, leg, ankle, etc. can measure a local blood pressure value. Under the condition that the measurement unit is detected to be arranged at the blood pressure measurement part of the user to be measured, the blood pressure measurement of the user to be measured can be carried out to obtain an initial measurement result; when it is detected that the measurement unit is not disposed at the blood pressure measurement site of the user to be measured, the blood pressure measurement may not be performed on the user to be measured.

As an embodiment, the measuring unit may include a contact sensor, and it is possible to detect whether the measuring unit is disposed at the blood pressure measuring site of the user to be measured by the contact sensor; the measuring unit may include an acceleration sensor, and it may be detected whether the measuring unit is disposed at the blood pressure measuring part of the user to be measured by the acceleration sensor; the measuring unit may include a pressure sensor, and whether the measuring unit is disposed at a blood pressure measuring location of the user to be measured or not may be detected by the pressure sensor, which is not limited herein.

In some embodiments, in a case where it is determined that the measurement unit is disposed at the blood pressure measurement site of the user to be measured, it may be detected whether instruction information for instructing to perform blood pressure measurement is received, where in a case where it is determined that the instruction information is received, the blood pressure of the user to be measured may be measured to obtain an initial measurement result, and in a case where it is determined that the instruction information is not received, the blood pressure of the user to be measured may not be measured. As an embodiment, the instruction information may be determined to be received when the target touch operation acting on the measurement unit is detected, or the instruction information may be determined to be received when the input target voice information is detected, or the like, which is not limited herein.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating an application scenario of the blood pressure measurement method according to the embodiment of the present application. As shown in fig. 2, the measurement unit 100 is disposed on the wrist of the user to be measured to measure the blood pressure of the user, and the correction unit 200 is disposed at a position flush with the heart of the user to be measured.

Step S120: and determining the gravity direction, and determining the relative distance and the relative direction between the correction unit and the correction unit, wherein the correction unit is arranged at a target position, and the height difference between the target position and the heart part of the user to be measured is fixed.

In this embodiment, in a case where the measurement unit obtains an initial measurement result, the relative positional relationship with the correction unit may be determined, wherein the relative positional relationship of the measurement unit and the correction unit may include: the relative distance and relative direction of the measuring unit and the correcting unit. The correction unit may be arranged at a target position, the height difference between the target position and the heart part of the user to be measured being fixed.

In some embodiments, the correction unit may be arranged in a position where the difference in height from the heart site of the user to be measured is fixed. For example, it is possible to attach the garment whose heart height is to be measured to the heart of the user during the blood pressure measurement by the measuring unit; the device can be arranged at the position of being flush with the heart of the user to be measured at the outside in the process of measuring the blood pressure by the measuring unit, and the height difference can be estimated to be zero at the moment, such as the device can be arranged on a seat backrest, a tabletop object, a bracket and the like; the device can be arranged at a position which is unchanged from the heart in the process of measuring the blood pressure by the measuring unit, such as a cap, a helmet, glasses, a waistband, a pocket, shoes, an external desktop, a seat, an instrument and the like, and the position with a fixed height is not limited.

As an embodiment, the measuring unit may include a first positioning module, the correcting unit may include a second positioning module, and the first positioning module and the second positioning module may implement a wireless ranging function, so that a relative distance and a relative direction between the measuring unit and the correcting unit may be determined through the first positioning module and the second positioning module.

As an embodiment, the measuring unit may comprise an inertial measuring unit, by means of which the measuring unit can determine the direction of gravity.

Step S130: and acquiring an included angle between the relative direction and the gravity direction, and determining a height difference between the relative distance and the correction unit based on the relative distance and the included angle.

In this embodiment, in the case where the measurement unit determines the relative direction and the gravitational direction, the angle between the relative direction and the gravitational direction may be calculated. In the case of obtaining the angle between the relative direction and the gravitational direction, the height difference between the measuring unit and the correction unit can be determined based on the relative distance and the angle.

In some embodiments, the measurement unit may detect whether the relative direction and the gravitational direction are in the same coordinate system, and if the relative direction and the gravitational direction are detected to be in the same coordinate system, may directly calculate the angle between the relative direction and the gravitational direction, and if the relative direction and the gravitational direction are detected to be not in the same coordinate system, may convert the relative direction and the gravitational direction to be in the same coordinate system, and in the case that the relative direction and the gravitational direction are determined to be converted to be in the same coordinate system, calculate the angle between the relative direction and the gravitational direction. For example, the conversion matrix between the coordinate system of the measuring unit and the coordinate system of the correcting unit can be obtained through the correction of the system in advance, so that the included angle between the relative direction and the gravity direction can be calculated.

In some embodiments, in the case of obtaining the relative distance and the angle between the relative direction and the gravity direction, the height difference between the measuring unit and the correcting unit may be obtained by calculating the relative distance and the angle between the relative direction and the gravity direction based on a preset formula. For example, assuming that the relative distance is d and the angle between the relative direction and the gravity direction is α, the height difference between the measurement unit and the correction unit may be obtained by calculating the relative distance and the angle between the relative direction and the gravity direction through h=d·cos α, where h is the height difference between the measurement unit and the correction unit in the gravity direction.

Step S140: and correcting the initial measurement result based on the height difference between the correction unit and the target position and the height difference between the heart part of the user to be measured to obtain a target measurement result.

Wherein the target measurement result is equivalent to the result of blood pressure measurement at the heart part which is flush with the user to be measured, and the measurement result is more accurate. That is, the deviation of the blood pressure value caused by gravity can be offset, and an accurate blood pressure value can be finally obtained.

In some embodiments, in case the height difference between the measuring unit and the correction unit is determined, the height difference between the measuring unit and the correction unit and the difference in height difference between the target position and the heart site of the user to be measured may be calculated, and the initial measurement result may be corrected based on the difference to obtain the target measurement result.

In some embodiments, in case the height difference between the measuring unit and the correction unit is determined, the measuring unit may calculate a sum of the height difference between the measuring unit and the correction unit and the height difference between the target position and the heart site of the user to be measured, and correct the initial measurement result based on the sum to obtain the target measurement result.

As an embodiment, the measurement unit may be preset with a first mapping relationship, where the first mapping relationship may include a plurality of height differences between the measurement unit and the correction unit, a plurality of height differences between the target positions and the heart part of the user to be measured, and a plurality of blood pressure adjustment parameters, and there are corresponding relationships among the plurality of height differences between the measurement unit and the correction unit, the plurality of height differences between the target positions and the heart part of the user to be measured, and the plurality of blood pressure adjustment parameters. Therefore, in the case that the measurement unit determines the height difference between the target position and the correction unit and the height difference between the target position and the heart part of the user to be measured, the measurement unit may determine the corresponding target blood pressure adjustment parameter based on the first mapping relationship, and correct the initial measurement result based on the target blood pressure adjustment parameter, thereby obtaining the target measurement result.

Referring to fig. 3, fig. 3 shows blood pressure values before and after the blood pressure correction provided in the embodiment of the present application, as shown in fig. 3, after the blood pressure correction, the blood pressure values more conform to normal blood pressure values.

The method is applied to the measuring unit, and will be described in detail with respect to the flow chart shown in fig. 8, and the blood pressure measuring method specifically includes the following steps:

Step S650: and if the blood pressure of the user to be measured does not meet the preset blood pressure based on the target measurement result, outputting first prompt information, wherein the first prompt information is used for prompting the measurement unit to be moved to a position flush with the heart part of the user to be measured.

In some embodiments, the measurement unit may preset and store a preset blood pressure, where the preset blood pressure represents a normal blood pressure interval of the user, and the preset blood pressure is used as a basis for determining the measured blood pressure of the user to be measured. Therefore, in this embodiment, when the measurement unit obtains the target measurement result, the measurement unit may determine the blood pressure of the user to be measured based on the target measurement result, and compare the blood pressure of the user to be measured with the preset blood pressure to determine whether the blood pressure of the user to be measured meets the preset blood pressure.

If it is determined that the blood pressure of the user to be measured meets the preset blood pressure, the blood pressure of the user to be measured is normal, and the original positions of the measuring unit and the correcting unit can be kept to continuously measure the blood pressure of the user to be measured.

If it is determined that the blood pressure of the user to be measured does not meet the preset blood pressure, the first prompt information is used for prompting that the measuring unit is moved to a position flush with the heart of the user to be measured, so that a height difference does not exist between the position of the blood pressure measurement and the heart of the user to be measured, the influence of the height difference on the blood pressure measurement can be avoided, and misjudgment of the blood pressure measurement is avoided. The outputting mode of the first prompt information may include: output in a voice manner, output in a text manner, output in a vibration manner, etc., and are not limited herein.

Step S660: and carrying out blood pressure measurement on the user to be measured under the condition that the measuring unit is determined to move to a position flush with the heart part of the user to be measured.

In this embodiment, the measurement unit may determine whether to move to a position flush with the heart of the user to be measured in the moving process, where when it is determined that the measurement unit moves to a position flush with the heart of the user to be measured, blood pressure measurement may be performed on the user to be measured. And then, comparing the measured blood pressure with the preset blood pressure, wherein if the measured blood pressure meets the preset blood pressure, the blood pressure of the user to be measured can be determined to be normal, and if the measured blood pressure does not meet the preset blood pressure, the blood pressure of the user to be measured can be determined to be abnormal, and alarm information can be output to prompt the user to seek medical advice as soon as possible.

Compared with the blood pressure measurement method shown in fig. 1, in the blood pressure measurement method provided by the embodiment of the invention, when the target measurement result indicates that the requirement of the user to be measured does not meet the preset blood pressure, the first prompt information for prompting the measurement unit to move to the position flush with the heart of the user to be measured is output, and when the measurement unit is determined to move to the position flush with the heart of the user to be measured, the blood pressure measurement is performed on the user to be measured, so that the problem of inaccurate blood pressure measurement caused by the measurement position is avoided, erroneous judgment of the blood pressure measurement is avoided, and the accuracy of the blood pressure measurement is improved.

Referring to fig. 9, fig. 9 is a flowchart illustrating a blood pressure measurement method according to an embodiment of the present application. The method is applied to the measuring unit, and will be described in detail with respect to the flow chart shown in fig. 9, and the blood pressure measuring method specifically includes the following steps:

step S710: and under the condition that the measuring unit measures the blood pressure of the user to be measured, acquiring an initial measuring result.

Step S720: and determining the gravity direction, and determining the relative distance and the relative direction between the correction unit and the correction unit, wherein the correction unit is arranged at a target position, and the height difference between the target position and the heart part of the user to be measured is fixed.

Step S730: and acquiring an included angle between the relative direction and the gravity direction, and determining a height difference between the relative distance and the correction unit based on the relative distance and the included angle.

Step S740: and correcting the initial measurement result based on the height difference between the correction unit and the target position and the height difference between the heart part of the user to be measured to obtain a target measurement result.

The specific description of step S710 to step S740 refer to step S110 to step S140, and are not described herein.

Step S750: and if the relative distance is greater than or equal to a distance threshold, outputting second prompt information, wherein the second prompt information is used for prompting shortening the distance between the second prompt information and the correction unit and/or prompting the measurement unit to be moved to a position flush with the heart part of the user to be measured.

In some embodiments, the measurement unit may preset and store a distance threshold value, where the distance threshold value is used as a judgment criterion for judging the relative distance between the measurement unit and the correction unit. Therefore, in the present embodiment, in the case where the relative distance between the measurement unit and the correction unit is obtained, the relative distance may be compared with the distance threshold to determine whether the relative distance is greater than or equal to the distance threshold, and a determination result may be obtained.

When the judgment result indicates that the distance between the measuring unit and the correcting unit is smaller than the distance threshold, the distance between the measuring unit and the correcting unit can be considered to be always, the blood pressure of the user to be measured can be accurately measured, and the blood pressure measurement of the user to be measured can be kept.

When the judgment result indicates that the relative distance between the measuring unit and the correcting unit is greater than or equal to the distance threshold, the distance between the measuring unit and the correcting unit can be considered to be too far, which may cause inaccuracy of the blood pressure measuring result, and a second prompt message can be output, where the second prompt message is used for prompting shortening the distance between the measuring unit and the correcting unit, and/or prompting that the measuring unit is one point to be flush with the heart part of the user to be measured. The outputting mode of the second prompt information may include: output in a voice manner, output in a text manner, output in a vibration manner, etc., and are not limited herein.

It can be understood that by outputting the second prompt message to prompt shortening the distance between the measuring unit and the correcting unit, the problem of inaccurate measurement of blood pressure by the measuring unit and the correcting unit caused by too far distance between the measuring unit and the correcting unit can be avoided. For example, assuming that the measurement unit is disposed on the wrist of the user to be measured, and the correction unit is disposed on the table surface flush with the height of the heart portion of the user to be measured, if the user to be measured is away from the table surface, the relative distance between the measurement unit and the correction unit may be increased, if the relative distance is increased to be greater than the distance threshold, a second prompt message may be output to prompt shortening of the distance between the measurement unit and the correction unit; if the user to be measured is close to the desktop, the relative distance between the measuring unit and the correcting unit is reduced, for example, the distance is reduced to be smaller than the distance threshold.

It can be understood that by outputting the second prompt message to prompt the measurement unit to be moved to a position flush with the heart of the user to be measured, the change of the relative distance between the measurement unit and the correction unit can be avoided, the influence on blood pressure measurement can be avoided, and the accuracy of blood pressure measurement can be improved.

Step S760: and carrying out blood pressure measurement on the user to be measured under the condition that the relative distance is determined to be shortened to be smaller than the distance threshold value.

In the present embodiment, during the movement of the measurement unit or the correction unit, it may be determined whether the distance between the measurement unit and the correction unit is smaller than the distance threshold. The distance between the measuring unit and the correcting unit is smaller than the distance threshold, so that the relative distance between the measuring unit and the correcting unit can be determined to be shortened to be smaller than the distance threshold, the distance between the measuring unit and the correcting unit can be considered to be within a normal range, the measurement of blood pressure cannot be influenced, and then the blood pressure measurement can be carried out on the user to be measured. When the distance between the measuring unit and the correcting unit is larger than or equal to the distance threshold, it can be determined that the relative distance between the measuring unit and the correcting unit is not shortened to be smaller than the distance threshold, and it can be considered that the distance between the measuring unit and the correcting unit exceeds the normal range and can influence the measurement of blood pressure, and then the second prompt information is continuously output.

Step S770: and carrying out blood pressure measurement on the user to be measured under the condition that the measuring unit is determined to move to a position flush with the heart part of the user to be measured.

Compared with the blood pressure measurement method shown in fig. 1, in the blood pressure measurement method provided by the embodiment of the present invention, when the relative distance between the measurement unit and the correction unit is greater than or equal to the distance threshold, the second prompting information is output, where the second prompting information is used to prompt shortening of the distance between the correction unit and the measurement unit, and prompt moving of the measurement unit to a position flush with the heart of the user to be measured, and when the relative distance is determined to be shorter than the distance threshold, the blood pressure measurement is performed on the user to be measured, or when the measurement unit is determined to be moved to a position flush with the heart of the user to be measured, the blood pressure measurement is performed on the user to be measured, so that the problem of inaccurate blood pressure measurement caused by too far distance between the correction unit and the measurement unit can be avoided, and accuracy of the blood pressure measurement is improved.
