Background

Blood Pressure (BP) is a lateral pressure acting on a blood vessel wall per unit area when blood flows in the blood vessel.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

FIG. 1 is a flow chart illustrating a method of blood pressure detection according to an exemplary embodiment. The method may be applied to terminal devices such as a desktop computer, a notebook computer, a tablet computer, and a smart phone, and is not limited herein, and as shown in fig. 1, the method may include:

step 100, aiming at a target time period, controlling a sphygmomanometer to acquire first blood pressure data of a measured object at a first time point and a second time point. The first time point is the starting time point of the target time period, and the second time point is the ending time point of the target time period.

Step 101, controlling the sphygmomanometer to collect the pulse data of the measured object in the target time period.

And step 102, controlling an electrocardiograph to acquire the electrocardiograph data of the measured object in the target time period.

Step 103, determining pulse wave propagation time in the target time period according to the pulse data and the electrocardiogram data, and determining second blood pressure data in the target time period according to the pulse wave propagation time.

And 104, determining the blood pressure change state in the target time period according to the first blood pressure data and the second blood pressure data.

In the disclosure, the sphygmomanometer may be a cuff type sphygmomanometer, and generally speaking, the cuff type sphygmomanometer may compress an artery blood vessel of a measured object by using an inflatable cuff, the artery blood vessel of the measured object shows a change process from a completely blocked state to a completely opened state gradually along with a decrease in cuff pressure, and blood pressure data of the measured object may be determined by identifying an overflowing sound and a corresponding pressure point in the process of blocked artery blood flow.

The blood pressure data may include, among other things, systolic and diastolic blood pressure. The blood pressure meter of the present disclosure may include, but is not limited to, any of the following: mercury column type sphygmomanometers, spring type sphygmomanometers, electronic sphygmomanometers, and the like.

An Electrocardiograph (Electrocardiograph) can automatically record bioelectric signals (electrocardiosignals) generated by myocardial activation during heart activity, and is a medical electronic instrument commonly used for clinical diagnosis and scientific research. The electrocardiograph of the present disclosure may include, but is not limited to, any of the following: single-channel, three-channel, six-channel and twelve-channel electrocardiographs and the like.

Pulse Transit Time (PTT) can be expressed as the time required for a pulse wave to travel between two points in an artery. Generally, when determining the pulse wave transit time, the electrocardiographic data and the pulse wave data may be acquired in the same time period, and the peak of the R wave of the QRS complex in the electrocardiographic data may be used as the start point of the propagation of the pulse wave from the aortic valve, the time point corresponding to the peak may be used as the start point time point, the peak of the first R wave after the start point time point in the pulse wave data may be used as the end point of the propagation of the pulse wave to the position where the pulse wave data is detected, and the time point corresponding to the end point may be used as the end point time point. The time interval from the starting point to the ending point can be used as the pulse wave propagation time, that is, the pulse wave propagation time is calculated by taking the peak value of the electrocardiograph R wave as the starting point and the peak value of the pulse wave in the same cardiac cycle as the ending point.

In the present disclosure, one or more pulse transit times may be determined within the target time period as desired, and are not limited herein.

The pulse wave conduction time is directly related to the arterial blood pressure, and the increase of the blood pressure can cause the tension of the arterial wall to increase, so that the pulse wave conduction speed is increased, and the pulse wave conduction time is reduced. On the contrary, the arterial blood pressure is reduced, the arterial wall tension is reduced, and the pulse wave conduction time is increased. The conversion between the pulse transit time and the blood pressure can be realized by establishing a correspondence (e.g., a linear function) between the pulse transit time and the blood pressure.

In the present disclosure, the target period may be any one of a plurality of periods. The plurality of time periods may be a plurality of continuous time periods or a plurality of discontinuous time periods, which is not limited by the present disclosure.

In one possible implementation, the plurality of time periods may be a plurality of time periods of equal length. For example, the sphygmomanometer may be controlled to collect the first blood pressure data of the subject every 15 minutes, each 15 minutes being one target time period, and the first blood pressure data of the subject collected by the sphygmomanometer each time may be used as the first blood pressure data of the previous target time period (the first blood pressure data at the end time point of the previous target time period) or the first blood pressure data of the next target time period (the first blood pressure data at the start time point of the next target time period).

In another possible implementation, the plurality of time periods may be a plurality of partially equal or mutually unequal time periods. For example, the first blood pressure data of the subject may be acquired every 15 minutes from 9 am to 21 pm of the day (i.e., when the subject is awake), and the first blood pressure data of the subject may be acquired every 30 minutes from 22 pm of the day to 8 am of the next day (i.e., when the subject is asleep). Thus, the blood pressure data can be acquired at different time intervals according to different states (such as waking state and sleeping state) of the object to be tested, and the influence of the acquired blood pressure on the object to be tested is reduced to the maximum extent.

As an example of the embodiment, the sphygmomanometer may be controlled to sequentially acquire first blood pressure data of the measured object with a time length of the target time period as an interval cycle, the electrocardiograph is controlled to acquire electrocardiograph data of the measured object in each target time period, and the sphygmomanometer is controlled to acquire pulse data of the measured object in each target time period. For each target time period, the pulse wave conduction time in the target time period can be determined according to the electrocardio data and the pulse data of the target time period. Then, the second blood pressure data in the target time period can be determined according to the pulse wave propagation time and through the corresponding relation (for example, a linear function) between the pulse wave propagation time and the blood pressure. The first blood pressure data corresponding to the start time point of the target time period, the first blood pressure data corresponding to the end time point of the target time period, and the second blood pressure data in the target time period may be collectively used as the blood pressure data of the object to be measured in the target time period. And on the basis, a curve of the blood pressure of the measured object changing along with time can be fitted to be used as the blood pressure change state of the measured object in the target time period.

Through the process, the blood pressure change state of the tested object in a long time can be more accurately reflected while the frequency of blood pressure collection of the sphygmomanometer is reduced as much as possible.

Generally, since the second blood pressure data determined according to the pulse wave propagation time may generate a large error, if the blood pressure of the measured object is determined by using only the pulse wave propagation time, the state of the blood pressure change of the measured object may not be truly reflected. In contrast, the cuff type sphygmomanometer can measure the blood pressure of a measured object more accurately, but the inflatable cuff uses a larger pressure intensity when collecting the blood pressure, which causes discomfort of the measured object, and thus cannot be applied to long-time high-frequency blood pressure detection.

The pulse wave conduction time in the target time period is determined according to the pulse data and the electrocardio data in the target time period, the second blood pressure data in the target time period is determined according to the pulse conduction time, the first blood pressure data acquired at the starting time point and the ending time point of the target time period are supplemented by the second blood pressure data to form sufficient blood pressure data, therefore, the frequency of blood pressure acquisition of a sphygmomanometer can be reduced as much as possible, the burden of a tested object cannot be increased, the blood pressure change state of the tested object in the target time period can be reflected more accurately, and accurate and efficient blood pressure detection is achieved.

FIG. 2 is a flow chart illustrating a method of blood pressure detection according to an exemplary embodiment. As shown in fig. 2, the difference between fig. 2 and fig. 1 is.

Step 100 may include: step 200, controlling the sphygmomanometer to acquire first blood pressure data of the measured object at a first time point and a second time point by adopting a first measured pressure.

Step 101 may include: step 201, controlling the sphygmomanometer to acquire the pulse data of the measured object by adopting a second measurement pressure in the target time period.

In the present disclosure, the first measurement pressure is greater than the second measurement pressure. For example, the first measured pressure may be much greater than the second measured pressure.

For example, the sphygmomanometer may be controlled to acquire first blood pressure data of the subject using a pressure of 150 mm hg (an example of a first measured pressure) at a start time point and an end time point of the target period, and to acquire pulse data of the subject using a pressure of 50 mm hg (an example of a second measured pressure) within the target period. And controlling an electrocardiograph to acquire the electrocardiogram data of the measured object in a target time period. The pulse wave conduction time in the target time period can be determined according to the electrocardio data and the pulse data in the target time period. Then, the second blood pressure data within the pulse wave transit time can be determined according to the pulse wave transit time and through the corresponding relation (for example, a linear model) between the pulse wave transit time and the blood pressure.

In the blood pressure detecting method of the embodiment, the pulse data of the measured object can be measured by the sphygmomanometer using the second measurement pressure which is smaller than the first measurement pressure, so that the measured object can be less uncomfortable when the sphygmomanometer collects the pulse data of the measured object by using the second measurement pressure. Therefore, the adverse effect of the measurement process on the measured object can be effectively reduced. In addition, the control sphygmomanometer disclosed by the invention adopts different pressures to measure the blood pressure data and the pulse data of the measured object respectively, is simple and convenient, does not need an additional device to measure the pulse data of the measured object, and further reduces the burden of the measured object.

the sphygmomanometer 31 may be connected to the control module 33, and is configured to collect first blood pressure data and pulse data of the measured object.

The electrocardiograph 32 may be connected to the control module 33, and is configured to acquire electrocardiographic data of the object.

For example, the sphygmomanometer 31 may be a cuff type sphygmomanometer. As shown in fig. 3, the inflatable cuff of the sphygmomanometer 31 may be wrapped around the upper arm of the subject. The monitoring probe of the electrocardiograph 32 is attached to the skin surface in the vicinity of the heart of the subject. The sphygmomanometer 31 and the electrocardiograph 32 may be linked with the control module 33 through a data line.

When the blood pressure detecting device starts to enter the working state, the control module 33 may control the sphygmomanometer to collect the blood pressure of the measured object at a preset frequency, and the interval duration of collecting the blood pressure each time may be the duration of the target time period. The control module 33 may control the sphygmomanometer 31 to acquire the first blood pressure data of the measured object using a pressure of 150 mmhg (an example of the first measured pressure) at the start time point and the end time point of the target time period, and control the sphygmomanometer 31 to acquire the pulse data of the measured object using a pressure of 50 mmhg (an example of the second measured pressure) within the target time period. The control module 33 can control the electrocardiograph 32 to acquire electrocardiographic data of the measured object in the target time period.

The control module 33 may determine the pulse wave transit time in the target time period according to the electrocardiographic data and the pulse data in the target time period, and may determine the second blood pressure data in the pulse wave transit time according to the pulse wave transit time and through a correspondence (for example, a linear model) between the pulse wave transit time and the blood pressure.

The control module 33 may use the first blood pressure data corresponding to the start time point of the target time period, the first blood pressure data corresponding to the end time point of the target time period, and the second blood pressure data in the target time period as the blood pressure data of the object to be measured in the target time period. And on the basis, a curve of the blood pressure of the measured object changing along with time can be fitted to be used as the blood pressure change state of the measured object.

In one possible implementation, the sphygmomanometer and the electrocardiograph may communicate with the control module in a wired manner or in a wireless manner, which is not limited herein.

According to the method, the sufficient blood pressure data is formed by supplementing the first blood pressure data acquired at the starting time point and the ending time point of the target time period by using the second blood pressure data, so that the frequency of acquiring the blood pressure by the sphygmomanometer can be reduced as much as possible, the burden of a tested object cannot be increased, and the blood pressure change state of the tested object in the target time period can be reflected more accurately. Moreover, the pulse data of the measured object can be measured by the sphygmomanometer by adopting the second measuring pressure intensity which is smaller than the first measuring pressure intensity, so that the measured object cannot be uncomfortable when the sphygmomanometer acquires the pulse data of the measured object by adopting the second measuring pressure intensity.
