As shown in fig. 5, the present application provides a blood pressure monitoring method according to another embodiment, which specifically includes the following steps:

s501: the blood pressure detection device is controlled to detect gesture detection data of a user, and the gesture detection data is received.

During sleep, the server 105 controls the blood pressure detection device 102 and/or the blood pressure detection device 103 to detect posture detection data of the user, and the server 105 receives the posture detection data from the blood pressure detection device 102 and/or the blood pressure detection device 103 through the terminal 104. The terminal 104 transmits the posture detection data to the server 105, so that the server 105 acquires the posture detection data of the user during sleep. Wherein, the blood pressure detection device 102 and/or the posture sensor integrated inside the blood pressure detection device 103 are used for detecting posture detection data of a user.

S502: and analyzing the sleeping gesture of the user at the current moment according to the gesture detection data.

The server 105 analyzes the sleeping posture of the user at the current moment according to the posture detection data, so that the server 105 can monitor the sleeping posture of the user in the sleeping process in real time.

S503: and selecting a blood pressure detection device from at least two blood pressure detection devices respectively worn at different parts of the user according to the sleeping posture of the current moment so as to detect the blood pressure of the user.

The server 105 selects a blood pressure detecting device from the blood

pressure detecting devices

102 and 103 respectively worn at different parts of the user according to the sleeping posture at the current time to detect the blood pressure of the user; for example, when the sleeping posture at the present time is lying on the left side, the server 105 selects the blood pressure detecting device 103 to detect the blood pressure of the user; the sleeping posture at the current moment is right side lying, and the server 105 selects the blood pressure detection device 102 to detect the blood pressure of the user; the sleep posture at the present time is supine or prone, and the server 105 selects the blood pressure detection device 102 or the blood pressure detection device 103 to detect the blood pressure of the user.

The server 105 selects the blood pressure detection device to perform blood pressure detection on the user, that is, the server 105 controls the blood pressure detection device to perform blood pressure detection on the user so as to detect blood pressure detection data of the user; for example, the server 105 controls the terminal 104 to supply power to the selected blood pressure detecting device (the blood pressure detecting device 102 or the blood pressure detecting device 103) to detect blood pressure detection data of the user. The blood pressure detection data may be blood pressure, heart rate, brain waves, blood oxygen saturation, or the like.

The server 105 of the embodiment selects the blood pressure detection device from at least two blood pressure detection devices respectively worn at different parts of the user according to the sleeping posture of the current moment to detect the blood pressure of the user, can monitor the blood pressure of the user in real time in the sleeping process, can avoid the blood pressure detection device from being pressed when the user lies on one side, and improves the accuracy of the detection result of the blood pressure detection device.

In an embodiment, as shown in fig. 6, step S503 may include the following steps:

s531: and determining the external pressure conditions of different parts of the user according to the sleeping posture at the current moment.

The server 105 determines the external pressure conditions suffered by different parts of the user according to the sleeping posture at the current moment; for example, the sleeping posture at the present time is lying on the left side, and the server 105 determines that the external pressure to which the left hand is subjected is greater than the external pressure to which the right hand is subjected; the sleeping posture at the present moment is lying on the right side, and the server 105 determines that the external pressure applied to the right hand is greater than the external pressure applied to the left hand.

S532: the blood pressure detecting device selects a portion where the external pressure is smallest, and detects the blood pressure of the user.

The server 105 selects a blood pressure detection device at a location where the external pressure is minimum to detect the blood pressure of the user; for example, when the sleeping posture at the present time is lying on the left side, the server 105 selects the blood pressure detection device 103 with the smallest external pressure to be applied to perform blood pressure detection on the user; when the sleeping posture at the present time is lying on the right side, the server 105 selects the blood pressure detection device 102 with the smallest external pressure to be applied to perform blood pressure detection on the user.

Since the configuration of the blood pressure detecting device 102 is the same as that of the blood pressure detecting device 103, the following embodiment will explain the blood pressure detection of the user by taking the blood pressure detecting device 102 as an example.

As shown in fig. 7, after the step of performing blood pressure detection on the user in the above blood pressure monitoring method, the blood pressure monitoring method may include the steps of:

s701: the blood pressure detection device is controlled to detect blood pressure detection data of a user and receive the blood pressure detection data.

The server 105 controls the blood pressure detection device 102 to detect the blood pressure detection data of the user, and the server 105 receives the blood pressure detection data of the user from the blood pressure detection device 102 through the terminal 104.

S702: and generating a blood pressure curve changing along with time according to the blood pressure detection data, and analyzing sleeping postures of the user in different time periods according to the posture detection data.

The server 105 generates a blood pressure curve which changes with time according to the blood pressure detection data, namely, the server 105 establishes a coordinate system, takes time as an abscissa of the coordinate system and takes the blood pressure detection data as an ordinate of the coordinate system; the server 105 generates a time-dependent blood pressure curve on a coordinate system from the blood pressure detection data. Therefore, the server 105 can monitor the blood pressure detection data of the user in the sleeping process in real time, and can remind the user to change the sleeping posture when the blood pressure detection data is abnormal. In addition, the server 105 may also analyze the sleep postures of the user at different periods according to the posture detection data.

S703: sleep attitudes are marked on the blood pressure curve.

The server 105 marks the sleep posture of the user on the blood pressure curve; the server 105 can send the blood pressure curve marked with the sleeping posture to the terminal 104, and the user can intuitively acquire the influence of the sleeping posture on the blood pressure through the terminal 104, so that the use experience of the user is improved.

S704: and carrying out statistical analysis on blood pressure detection data under different sleeping postures.

The server 105 performs statistical analysis on the blood pressure detection data in different sleep postures. Specifically, the server 105 counts at least one or a combination of the average blood pressure value, the blood pressure fluctuation value, and the frequency of blood pressure fluctuation in different sleep postures from the blood pressure detection data. For example: the server 105 may count the blood pressure detection data in the sleep posture of supine to obtain at least one or a combination of an average blood pressure value, a blood pressure fluctuation value, and a blood pressure fluctuation frequency in the sleep posture of supine; the server 105 may count the blood pressure detection data when the sleep posture is lateral lying, to obtain at least one or a combination of an average blood pressure value, a blood pressure fluctuation value, and a blood pressure fluctuation frequency when the sleep posture is lateral lying; the server 105 may count the blood pressure detection data when the sleep posture is prone, and obtain at least one or a combination of the average blood pressure value, the blood pressure fluctuation value, and the blood pressure fluctuation frequency when the sleep posture is prone.

S705: and recommending the sleep posture to the user according to the statistical analysis result.

The server 105 recommends the sleep posture to the user according to the statistical analysis result, specifically, the server 105 recommends the sleep posture with the lowest at least one or combination of the average blood pressure value, the blood pressure fluctuation value, and the blood pressure fluctuation frequency to the user. The server 105 may recommend a sleep posture with a relatively low blood pressure fluctuation value to the user, for example, if the blood pressure fluctuation value is minimum when the sleep posture is lateral, the server 105 recommends that the sleep posture is lateral to the user through the terminal 104.

The server 105 may preset a threshold range, and the server 105 further compares the blood pressure detection data with the threshold range; if the server 105 determines that the blood pressure detection data exceeds the threshold range, the server 105 sends a reminding message to the user through the terminal 104 to remind the user that the blood pressure detection data is abnormal.

The server 105 in this embodiment performs statistical analysis on the blood pressure detection data under different sleep postures, and recommends the sleep postures to the user according to the statistical analysis result, so that the sleep postures can be recommended in real time according to the blood pressure detection data, and the user experience is improved.

As shown in fig. 8, after step S702, the blood pressure monitoring method may include the steps of:

S801: the blood pressure detection device is controlled to detect motion detection data of a user and receive the motion detection data.

The server 105 controls the blood pressure detecting device 102 to detect the motion detection data of the user, and transmits the motion detection data to the server 105 through the terminal 104 so that the server 105 receives the motion detection data of the user.

S802: and analyzing the sleep quality of the user according to the motion detection data.

The server 105 analyzes the sleep quality of the user according to the motion detection data, that is, the server 105 can analyze the motion amplitude and the motion frequency of the user according to the motion detection data; and determining the sleep quality of the user according to the action amplitude and the action frequency of the user, wherein the sleep quality is worse as the action amplitude and the action frequency are larger.

For example, the blood pressure detecting device 102 may establish a connection with the terminal 104 through bluetooth, the blood pressure detecting device 102 uses the terminal 104 as a reference object, when the blood pressure detecting device 102 moves, the blood pressure detecting device 102 obtains the distance between the blood pressure detecting device 102 and the terminal 104 through bluetooth protocol, and records the moving time, and at this time, the motion detection data includes the distance and the moving time; the server 105 can analyze the motion amplitude of the user according to the change of the distance, and can analyze the motion frequency according to the moving time. The server 105 may divide the sleep quality into a good, a neutral, and a bad, and compare the motion amplitude and the motion frequency with a preset motion amplitude threshold and motion frequency threshold to determine the sleep quality of the user.

S803: sleep quality is marked on the blood pressure curve.

The server 105 further marks the sleep quality on the blood pressure curve, e.g. the server 105 marks the corresponding sleep quality on the blood pressure curve according to time.

The server 105 of the present embodiment analyzes the motion amplitude and the motion frequency of the user based on the motion detection data; and the sleep quality of the user is determined according to the action amplitude and the action frequency of the user, so that the accuracy of the analysis result can be improved.

In an embodiment, the server 105 may receive blood pressure detection data of a plurality of users, and generate a labeled blood pressure curve for each user, and share the labeled blood pressure curve among the plurality of users, where the labeled blood pressure curve is the blood pressure curve disclosed in the foregoing embodiment. When the user sets the shared blood pressure curve through the terminal 104, the server 105 sends the marked blood pressure curve to the terminals 104 of other users, so as to share the marked blood pressure curve among multiple users.

The steps of the blood pressure monitoring method disclosed in the above embodiments may be implemented on the terminal 104, and are not described herein. How the server 105 acquires health information of the human body is described in detail below.

Because the health information of the human body often needs abundant empirical data and reasoning rules to obtain, and the server 105 can acquire abundant blood pressure detection data and has stronger data processing capability, the embodiment can analyze the blood pressure detection data through the server 105 so as to acquire the health information of the human body, and can improve the accuracy of blood pressure pulse condition detection and data processing. The terminal 104 of the embodiment displays the health information and the blood pressure detection data, so that the user can know the health condition of the user in time, and the disease risk is reduced.

Specifically, the server 105 may pre-store blood pressure detection data, which may include a normal blood pressure detection data range, a plurality of blood pressure detection data of the same human body, a plurality of blood pressure detection data of the human body, and the like. The server 105 may also pre-store other physiological data and mapping relationships between other physiological data and blood pressure detection data. The server 105 may analyze the blood pressure detection data forwarded by the terminal 104 according to pre-stored blood pressure detection data to obtain health information of the human body. For example, the server 105 may compare the blood pressure detection data of the human body a forwarded by the terminal 104 with a normal blood pressure detection data range, or compare the blood pressure detection data of the human body a forwarded by the terminal 104 with the previous blood pressure detection data of the human body a, or compare the blood pressure detection data of the human body a forwarded by the terminal 104 with the blood pressure detection data of the human body B, so as to obtain health information of the human body a according to the comparison result.

The blood pressure detection data may include pulse waves, which are periodic pressure waves generated by the pulsation of the heart pushing blood along a blood vessel. The pulse wave of human body contains abundant physiological information such as blood pressure, heart rate and cardiovascular information. Cardiovascular health information can be obtained through analysis of pulse waveforms to reduce occurrence of cardiovascular diseases.

Alternatively, to improve the accuracy of the health information, the server 105 needs to perform filtering processing on the plurality of pulse waves after acquiring the plurality of pulse waves from the terminal 104 to reject interference noise.

Specifically, the server 105 acquires the amplitude of the pulse wave, and determines whether the amplitude is within a preset amplitude range; if so, the server 105 determines that the pulse wave with the amplitude within the preset range is the first pulse wave, and filters out the pulse waves except the first pulse wave. Further, the server 105 may obtain the amplitude of the characteristic point of the first pulse wave, where the characteristic point may include a reflected wave point, a peak point, a trough point, or other extreme point or inflection point, etc. of the first pulse wave.

Of course, in another embodiment, the server may also acquire the period of the pulse wave, and filter the pulse wave whose period is not within the preset period, so as to acquire the first pulse wave, that is, take the period as the filtering condition. Of course, in other embodiments, the amplitude and period of the pulse wave may also be used as filtering conditions.

Different human bodies or the same human body in different health states generate different pulse waves, namely different pulse conditions. The common pulse conditions in TCM include slippery pulse, rapid pulse, wiry pulse, flat pulse, floating pulse, deep pulse, delayed pulse, rapid pulse, and deficient pulse, and the waveforms of the pulse conditions are different from each other as shown in FIG. 9.

Different pulse conditions characterize different health conditions of the human body, and in order to improve accuracy of the health information, the server 105 of this embodiment further identifies the pulse condition (waveform) of the first pulse wave.

Specifically, the server 105 of the present embodiment stores a preset waveform including at least a slippery pulse waveform, a pulse-promoting waveform, a wiry pulse waveform, a flat pulse waveform, or the like. After filtering the plurality of pulse waves forwarded by the terminal 104, the server 105 matches the first pulse wave with a preset waveform; the server 105 further obtains a preset waveform matched with the first pulse wave as a first preset waveform, and obtains health information according to the first preset waveform. For example, if the server 105 determines that the first pulse wave forwarded by the terminal 104 matches a preset pulse wave, it determines that the first pulse wave is a pulse; the server 105 may further transmit the first pulse wave or the first predetermined waveform and the health information "pulse" back to the terminal 104.

Alternatively, the server 105 obtains the first characteristic information of the first pulse wave and the second characteristic information of the preset waveform, respectively, and if the difference between the first characteristic information and the second characteristic information is smaller than the preset difference, the server 105 determines that the first pulse wave matches the preset waveform.

Specifically, the feature information of the present embodiment may include information of a waveform period and a waveform standing point (including an extreme point and an inflection point) of the first pulse wave. The waveform standing point information comprises the number of waveform standing points, the time interval between adjacent waveform standing points and the like.

As shown in fig. 9, the pulse-promoting waveform period is greatly different from the waveform periods of other pulse conditions, and if the server 105 determines that the difference between the waveform period of the first pulse wave and the waveform period of the preset pulse-promoting waveform is smaller than the preset difference, the first pulse wave can be determined as pulse-promoting. If the server 105 determines that the difference is greater than the preset difference, it further determines whether the number of waveform extreme points of the third pulse wave is 2 (the number of waveform extreme points of the preset sliding pulse is 2), and determines whether the amplitude of the second waveform standing point is greater and lower than the first waveform standing point; if so, the third pulse wave can be judged as a slippery pulse. If the server 105 determines that the number of waveform extreme points of the third pulse wave is equal to 3, it may further determine whether the interval time between the first waveform standing point and the second waveform standing point of the third pulse wave is smaller than the preset time (the time interval between the first waveform standing point and the second waveform standing point of the preset chord pulse); if so, the first pulse wave can be judged as chordal pulse.

The present embodiment can identify the pulse condition (waveform) of the pulse wave through the waveform period and the waveform standing point information of the pulse wave. Of course, in other embodiments, the pulse condition (waveform) of the pulse wave may also be identified according to other characteristic information of the pulse wave. Of course, the server 105 may filter the obtained waveform standing points before performing pulse condition recognition to reduce noise interference.

Pulse diagnosis is one of four diagnostic methods in TCM, and is a unique diagnostic method. The pulse diagnosis device mainly analyzes the characteristics of 'position, number, shape, potential' and the like of pulse by using finger feeling so as to judge the functional state of viscera, thereby realizing the purpose of noninvasive diagnosis and having positive significance for diagnosis and treatment of diseases.

The existing pulse condition instrument can perform the pulse feeling process, patterns and displays pulse waves, so that a user intuitively knows pulse conditions through the pulse waves, but acquires health information from the pulse conditions, and abundant clinical experience is required, so that non-medical staff or non-professional medical staff can hardly accurately acquire the health information from pulse condition waveforms.

To solve the above-described problems, the server 105 of the present embodiment further analyzes the first pulse wave to acquire more specific human health information from the first pulse wave, and the health information of the present embodiment includes information such as blood pressure, pulse force, pulse rate, pulse rhythm, and reflected wave enhancement index (AI) reflecting elasticity of an artery, in addition to pulse condition information.

Specifically, the server 105 obtains several pulse waves, such as 3 pulse waves, with the maximum pulse wave amplitude in the whole measurement process, and obtains the pulse force of the human body by taking the average value according to the amplitude of the peak point. The larger the amplitude of the mean value is, the larger the pulse force is, and the magnitude of the pulse force represents the strength of the physique of the human body; the server 105 may also obtain pulse rate, pulse law, AI value, etc. from the first pulse wave.

The server 105 transmits the obtained health information back to the terminal 104, and the terminal 104 displays the health information, as shown in fig. 10 and 11.

Further, the server 105 stores a preset range, and determines whether the health information is within the preset range; if yes, the health information display state on the control terminal 104 is normal; if not, the health information display state on the terminal 104 is abnormal.

The server 105 may also transmit the first pulse wave or the pulse waveform corresponding to the first pulse wave, the type of the first pulse wave, the blood pressure data, etc. back to the terminal 104, and the terminal 104 displays the pulse waveform, the type, the blood pressure data, etc.

Optionally, the server 105 of the present embodiment further obtains health information of blood vessel elasticity of the human body according to the reflected wave point and the peak point, for example, if the server 105 determines that the reflected wave point is on the right side of the peak point (as shown in fig. 10), the obtained health information is that the blood vessel elasticity is better; if the server 105 determines that the reflected wave point is on the left side of the peak point (as shown in fig. 11), the acquired health information is poor in blood vessel elasticity.

The server 105 can also obtain health information such as bradycardia or tachycardia, arrhythmia and the like according to the heart rate data; the server 105 may also obtain arterial health information based on the AI value. The terminal 104 may also display such health information.

Compared with the prior art, the embodiment analyzes the blood pressure detection data through the server 105 to acquire the health information of the human body, and can improve the accuracy of blood pressure pulse condition detection and data processing; moreover, the terminal 104 of the present embodiment can display detailed health information, not just pulse wave, so that non-medical staff can also clearly know their health status through the health information.
