Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blood pressure detection and management, and particularly relates to a blood pressure management system and method. BACKGROUND

[0002] Blood pressure is one of the indexes for analyzing circulatory system diseases, and risk analysis based on blood pressure is helpful for preventing diseases of the cardiovascular system such as stroke, heart failure or myocardial infarction. With the rapid development of China's social economy, people's lifestyle has changed greatly, and with the arrival of population aging, the incidence of hypertension in China is rising in a well pattern, and hypertension has become a major cardiovascular disease threatening the health of the nation. Therefore, more and more people begin to measure and monitor blood pressure.

[0003] At present, the devices for measuring blood pressure on the market are mainly electronic sphygmomanometers based on the oscillometric method or the Korotkoff method, or portable non-invasive blood pressure measurement methods based on the photoelectric method. Among them, the blood pressure measurement method based on the oscillometric method or the Korotkoff method is still the standard for measuring blood pressure and performing risk analysis based on blood pressure.

[0004] In the past, blood pressure measured at hospitals, outpatient treatment or physical examination was used for health diagnosis. In recent years, people generally realize that blood pressure measured randomly at home or in any occasion may be more helpful for the diagnosis of circulatory system diseases than immediate blood pressure measured by specially going to designated medical institutions, so more and more families may use home blood pressure meters, and the measurement method of the home blood pressure meter is as follows: a cuff is wound on a measurement site such as an upper arm, the internal pressure of the cuff is pressurized to be only higher than systolic blood pressure by a specified pressure, and then the cuff pressure is gradually or periodically reduced. The volume change of the artery in the process of reducing the pressure is detected as the pressure change superimposed on the cuff pressure, and the systolic and diastolic blood pressures are determined according to the change in the amplitude of the pressure pulse wave.

[0005] In addition, similar to the oscillometric method, the blood pressure measurement method based on the Korotkoff method is to wind a cuff on a measurement site (such as an upper arm), pressurize the cuff pressure to be only higher than systolic blood pressure by a specified pressure, use a microphone arranged in the cuff to detect the Korotkoff sound generated by the artery in the process of gradually reducing the cuff pressure, determine the cuff pressure at which the Korotkoff sound is generated as the systolic blood pressure, and determine the cuff pressure at which the Korotkoff sound is weakened or disappears as the diastolic blood pressure.

[0006] Although the existing cuff-based blood pressure measurement devices have relatively accurate measurement results, these devices are usually set up in health service institutions such as hospitals, clinics, etc., or need to be measured quietly in a suitable place, and sometimes need to be supervised by medical experts or experienced persons, and are not suitable for use at any time and any place, especially in some cases where blood pressure needs to be measured suddenly or blood pressure data needs to be collected, most people cannot immediately obtain standard medical-grade blood pressure measurement devices; in addition, the cuff-based blood pressure measurement device has certain constraints and compression on the human body, which is easy to cause discomfort, and cannot realize long-term continuous monitoring of blood pressure in daily life.

[0007] Portable blood pressure monitoring products are usually wearable (such as smart bracelets), and most of them are designed based on photoelectric sensors. Such products mainly detect the volume change of blood (mainly arterial blood) in living tissues through photoelectric means, that is, a light beam of a certain wavelength is irradiated to the skin surface, the light beam is transmitted or reflected to the photoelectric receiver, based on the fluid model and the light absorption characteristics of the skin, it is concluded that the change of light absorption of the skin is directly related to the change of arterial blood flow rate, and then the change of arterial blood flow rate is calculated according to the change of light absorption of the skin, to obtain the blood pressure value at a certain time point.

[0008] However, the monitoring results of portable blood pressure monitoring devices are easily affected by the environment, such as being easily disturbed by light based on the principle of optical measurement, or the sparseness of the body hair on the skin surface, or even the skin color of the measured person will affect the photoelectric volume scan signal; secondly, in order to improve the accuracy, these devices usually also assist in monitoring the electrocardiogram signal, such as ECG and PPG combined to measure blood pressure, so the overall analysis method is relatively complex, and the portable blood pressure monitoring device (such as a smart bracelet) itself has limited data authenticity and reliability compared with a medical-grade electrocardiogram monitor, so there is still a large error in the final monitoring result. Therefore, these portable blood pressure measurement devices usually cannot accurately measure the blood pressure state.

[0009] In summary, it is necessary to provide a blood pressure management system and method which has accurate measurement results and can correctly guide or assist users in blood pressure monitoring and improve the health quality of users, so as to accurately monitor or quantify the blood pressure of users at any time without standard medical-grade blood pressure monitoring devices.

[0042] Figure 2 is a structural block diagram of a second blood pressure collection device of a preferred embodiment provided by the present application. DETAILED DESCRIPTION

[0043] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art, and the protection scope of the present application can be more clearly defined.

[0044] Various embodiments and / or implementations herein relate to a management system and method thereof for monitoring and quantifying blood pressure of a user by utilizing user data.

[0045] Embodiment 1

[0046] The present application provides a blood pressure management system, referring to Figure 1 may include a first blood pressure collection device and a second blood pressure collection device allowing interaction with blood pressure measurement values related to the measured person. Specifically, the first blood pressure collection device and the second blood pressure collection device can establish real-time or offline data interaction relationship through a cloud server or a third-party intelligent terminal.

[0047] Specifically, the first blood pressure collection device can be attached to the measured person in a wearable manner to determine or obtain the first blood pressure state metric associated with time of the measured person, and at least one physiological feature data associated with the first blood pressure state metric of the measured person.

[0048] Further, the second blood pressure acquisition device, which is operatively attached to the subject, is capable of determining a blood pressure state matching the first blood pressure state metric based on at least one physiological characteristic data determined or acquired by the first blood pressure acquisition device or the external device, and acquiring a second blood pressure state metric of the blood pressure state.

[0049] The processor is capable of correcting the first blood pressure state metric acquired by the first blood pressure acquisition device based on the second blood pressure state metric determined by the second blood pressure acquisition device.

[0050] According to a preferred embodiment, in the present application, the blood pressure state metric can include any one or a combination of 24-hour average systolic pressure, average diastolic pressure, average pulse pressure and basal blood pressure. Further, the determination result of the blood pressure state of the subject can be any one or a combination of a graph, a curve and a text.

[0051] According to a preferred embodiment, in the present application, the first blood pressure acquisition device can be a wearable / worn blood pressure monitoring device. Specifically, one example of the wearable / worn blood pressure monitoring device can be a smart wristwatch and the like, and such a wristwatch-type blood pressure monitoring device usually determines the blood pressure of the subject by using a photoplethysmography (PPG) and / or electrocardiogram (ECG) signal-based photoelectric method. It should be understood that the present application does not intend to specifically limit the specific structure of the wearable / worn blood pressure monitoring device, and thus the wearable / worn first blood pressure acquisition device can also be in other wearable / worn forms.

[0052] According to a preferred embodiment, in the present application, the first blood pressure acquisition device can include:

[0053] The device body is wearable attached to the measurement site of the subject.

[0054] The pulse wave acquisition module is configured to acquire a pulse wave signal of the subject associated with time.

[0055] The ECG acquisition module is configured to acquire an ECG signal of the subject associated with time.

[0056] The processing module is configured to determine at least one blood pressure state metric of the subject based on the pulse wave signal and / or the ECG signal of the subject associated with time.

[0057] Specifically, the first blood pressure acquisition device such as a smart wristwatch / wristband usually includes a wearable / worn device body such as a wristwatch / wristband housing and a watchband for attachment to the subject. Specifically, the wristwatch / wristband housing is connected to the watchband. The watchband is usually made of a flexible material that can be bent, so that the watchband can be wound to be fixed to the measurement site (such as the wrist) of the subject.

[0058] According to a preferred embodiment, the device body can generally comprise a processing module (central processing unit, CPU), a pulse wave acquisition module, an electrocardio acquisition module, a storage module, and the like. Further, the watch case provides a housing space for the processing module (central processing unit, CPU), the pulse wave acquisition module, the electrocardio acquisition module, the storage module, and the like. In particular, the pulse wave acquisition module and / or the electrocardio acquisition module can be any device, wearable, sensor, or other element capable of obtaining data from the subject. The pulse wave acquisition module and / or the electrocardio acquisition module can be in direct communication with the subject, or can obtain information from the subject via indirect contact (such as video, IR, motion detector, or other types of sensors).

[0059] According to a preferred embodiment, in the present application, the pulse wave acquisition module can be used to obtain the pulse wave signal of the subject. Specifically, one particular example for obtaining the pulse wave signal of the subject can be to obtain the pulse wave signal by photoplethysmography, i.e. to use a photoelectric sensor to collect the pulse wave waveform of the wrist of the subject, and to determine the blood pressure value of the subject by a calculation formula corresponding to the characteristic parameters (such as the rising slope of the pulse wave and the wave band time) contained in the pulse wave waveform. In particular, the present application does not intend to improve the method of obtaining the pulse wave signal, and therefore other methods capable of obtaining the pulse wave signal of the subject can also be applied to the present application.

[0060] According to a preferred embodiment, in the present application, the electrocardio acquisition module can be used to obtain the electrocardio signal of the subject. Specifically, the current portable electrocardio monitoring device (such as a smart watch / bracelet) measures the electrocardio of the subject generally based on the PPG method, i.e. to monitor the heartbeat by measuring the reflected light: a light of a certain wavelength is irradiated to the skin tissue of the human body, and the received light signal is converted into an electrical signal by the photoelectric receiving tube of the receiving end. In particular, since the blood flow in the skin tissue changes periodically with the pulse, and the proportion of oxygenated hemoglobin in the blood also changes with the pulse, the degree of absorption of incident light by them also changes periodically with the pulse, which is reflected in the receiving end, i.e. the received electrical signal also changes with the pulse, and the heart rate represented by this electrical signal can be demodulated by a preset algorithm.

[0061] Alternatively, the ECG acquisition device can also acquire the ECG signal of the subject by a bioelectric potential (e.g. ECG) based measurement method. Specifically, the ECG acquisition module can include a plurality of detection electrodes and a signal processing module. The detection electrodes are signal connected to the signal processing module. Further, at least one of the detection electrodes can be arranged on the surface of the watch / bracelet, and at least one other detection electrode can be arranged on the bottom surface of the watch / bracelet. When the user wears the watch / bracelet, the electrodes on the bottom surface of the watch / bracelet are contacted. When measurement is needed, the subject can touch the electrodes on the surface of the watch / bracelet with the other hand to form a measurement loop. The signal processing module can acquire the ECG signal from the electrical signal in the measurement loop formed by the two detection electrodes, and determine the ECG value of the subject from the ECG signal according to existing algorithms. In particular, the present application does not intend to improve the method of acquiring the ECG signal, and therefore other methods capable of acquiring the ECG signal of the subject can also be applied to the present application.

[0062] According to a preferred embodiment, the PPG and ECG based blood pressure measurement method is relatively mature in the prior art, and the present application does not intend to improve it. Specifically, the process of measuring blood pressure by combining ECG and PPG is as follows: the pulse wave (PPG) and ECG signal of the wrist part are acquired by the photoelectric sensor, and the time difference (PTT) between the pulse wave (PPG) and ECG signal is analyzed, which has a certain correlation with the systolic blood pressure (SBP) and / or diastolic blood pressure (DBP) of the subject, and can be calculated by a corresponding calculation formula or PTT model.

[0063] According to a preferred embodiment, the storage module of the first blood pressure acquisition device can be used to store the initial ECG data acquired by the ECG acquisition module and the calculation data after signal conversion and analysis processing. In addition, the first blood pressure acquisition device usually also includes a communication interface, which allows the first blood pressure acquisition device to interact with other external devices / apparatuses, so that the data related to the blood pressure detection task of the subject stored in the storage module can be shared or exchanged.

[0064] According to a preferred embodiment, the first blood pressure acquisition device can also include a time synchronization module. Specifically, the time synchronization module can be used to provide a standard time signal. The standard time signal can be used for time calibration of the respective work of different modules and devices.

[0065] According to a preferred embodiment, based on the standard time signal determined by the time synchronization module, the electrocardio signal and the pulse wave signal can be determined by the electrocardio signal acquisition module and the pulse wave signal acquisition module, respectively, according to the standard time signal to ensure the synchronization of the electrocardio signal and the pulse wave signal, so as to improve the accuracy of the measurement results. In other words, based on the standard time signal, the electrocardio signal and the pulse wave signal are taken as the reference at the same time node, so as to ensure the synchronization of the electrocardio signal and the pulse wave signal.

[0066] According to a preferred embodiment, when the processing module (central processing unit, CPU) calculates or determines the blood pressure measurement value of the subject, the output interface can be used to transmit the blood pressure measurement value to an external device, such as a computer, a mobile phone, etc., for display or analysis, or the output interface can be used to upload the blood pressure measurement value to a cloud database / server, so that the subject can obtain more comprehensive data analysis results.

[0067] According to a preferred embodiment, the portable first blood pressure acquisition device usually further comprises a display module. The display module can be used to display the blood pressure measurement result determined by the processing module (central processing unit, CPU). In particular, the display module can display the blood pressure measurement result of the subject by any means capable of conveying information. For example, by one or more of display, vibration, sound / light, etc. Alternatively, the blood pressure measurement result can be provided via an interface, which can be a monitor, a mobile device, a laptop, a desktop computer, or a home computing device, etc.

[0068] According to a preferred embodiment, the portable first blood pressure acquisition device can usually be used to obtain one or more physiological characteristic data of the subject. Specifically, the physiological characteristic data can usually include data signals such as the body temperature, motion, heart rate, and respiratory rate of the subject. In particular, the physiological characteristic data such as the body temperature, motion, heart rate, and respiratory rate are stored in relation to time. Accordingly, the portable first blood pressure acquisition device can comprise an acquisition module for obtaining these physiological characteristic data, such as one or more of a temperature sensor, a heart rate sensor, a respiration sensor, and a motion sensor.

[0069] According to a preferred embodiment, since the blood pressure change of a person has a certain correlation with the physiological parameters thereof, such as the fluctuation of the blood pressure with the body temperature, respiration, and heart rhythm of the person, etc. Therefore, the general blood pressure acquisition device can determine the blood pressure change state of the human body, including the 24-hour average systolic pressure, average diastolic pressure, average pulse pressure, and basal blood pressure, etc., according to the physiological signals of the human body, such as the body temperature, heart rate, and respiratory rhythm, etc. In particular, the physiological characteristic data of the subject can be a waveform graph, such as a body temperature waveform graph, a heart rate waveform graph, and / or a respiration waveform graph.

[0070] According to a preferred embodiment, the processor can divide the acquired physiological characteristic data waveform into a plurality of segmented waveforms, and extract characteristic data such as body temperature data, heart rate data, or respiration data from the segmented waveform graphs, to classify the blood pressure variation state of the subject according to the characteristic data in the segmented waveform graphs. In particular, the processor classifies the blood pressure state of the user based on the characteristic data in the segmented waveform graphs can be through machine learning, pre-determined threshold programming, or medical personnel self-setting, etc.

[0071] According to a preferred embodiment, the first blood pressure acquisition device can compare the acquired blood pressure measurement result of the subject with the reference value, and determine the blood pressure state or health quality of the subject according to the difference between the blood pressure measurement result and the reference value. For example, if the blood pressure measurement result exceeds the reference value range, the current subject may have mild hypertension.

[0072] According to a preferred embodiment, in the present application, the second blood pressure acquisition device can be a hospital, outpatient, or other medical institution, or a medical-grade blood pressure monitoring device that can be used at home. Specifically, the second blood pressure acquisition device can be a blood pressure monitoring device based on the oscillometric method and / or the Korotkoff sound method.

[0073] According to a preferred embodiment, in the present application, the second blood pressure acquisition device can include:

[0074] A detection cuff with an air bag for winding around the measurement site of the subject.

[0075] An air pump for providing air to the air bag.

[0076] An air valve for discharging air from the air bag.

[0077] A pressure detection module for detecting the pressure change of the air bag due to the entry and / or discharge of air.

[0078] A processor for calculating at least one blood pressure state metric indicator of the subject according to the pressure change of the air bag.

[0079] Specifically, referring to Figure 2 A blood pressure monitoring device based on the oscillometric method and / or the Korotkoff sound method, such as the second blood pressure acquisition device, generally includes a detection cuff for winding around the measurement site (such as the upper arm) of the subject and a device main body, which can be connected through an air duct. Further, the device main body generally also includes a display module and an operation module.

[0080] According to a preferred embodiment, the operation module can include a power switch for starting and stopping the device, a measurement switch for switching the detection action, a pause switch for stopping the detection action, and the like. The display module can include a display screen for displaying at least the blood pressure measurement result of the subject. Alternatively, the display module can be a touch display screen.

[0081] According to a preferred embodiment, the detection cuff can include an air bag connected to the air pump and the air valve through an air pipe. On the other hand, the device main body of the second blood pressure acquisition device based on the oscillometric method and / or the Korotkoff method can include a pressure detection module (such as a pressure sensor), an air pump, and an air valve. The pressure sensor, the air pump, and the air valve are connected to the air bag of the detection cuff through an air pipe for providing the air bag with flow-controllable air. Further, the pressure sensor can be electrically connected with the oscillation circuit. The air pump and the air valve can be electrically connected with the driving circuit.

[0082] According to a preferred embodiment, the device main body of the second blood pressure acquisition device generally further includes a processing module (central processing unit CPU), a storage module, and a communication interface, and the like. Specifically, the central processing unit CPU is used to control the operation of the entire blood pressure monitoring device, including but not limited to the analysis and processing of data. The storage module can be used to store the initial pressure data collected by the pressure sensor and the calculation data after signal conversion and analysis processing. Through the communication interface, one or more external devices can be externally connected to allow the data related to the blood pressure detection task of the subject to be shared or exchanged.

[0083] According to a preferred embodiment, the central processing unit is generally further electrically connected with the oscillation circuit, the driving circuit, and the display module and the operation module.

[0084] According to a preferred embodiment, the pressure detection module can be an electrostatic capacity type pressure sensor, the capacitance value of which can change according to the pressure change in the air bag of the detection cuff. Further, when the pressure sensor is working, the oscillation circuit connected thereto can input an oscillation frequency signal corresponding to the capacitance value of the pressure sensor to the central processing unit.

[0085] According to a preferred embodiment, the central processing unit can execute the computer program instructions stored in the memory in response to the operation instructions input by the operation module, so as to output a control signal to the driving circuit connected with the air pump and the air valve, so that the driving circuit drives the air pump and the air valve to work based on the control signal.

[0086] According to a preferred embodiment, the driving circuit can control the air pump to input air to the air bag of the detection cuff based on the control signal output by the central processing unit. Alternatively, the driving circuit can control the opening and closing of the air valve based on the control signal output by the central processing unit so as to exhaust the air in the air bag of the detection cuff.

[0087] According to a preferred embodiment, the central processor is capable of calculating the blood pressure value of the subject based on the pressure change of the air bag of the detection cuff acquired by the pressure sensor, and outputting a control signal for displaying the blood pressure measurement result to the display module. In addition, the central processor is capable of storing the blood pressure measurement result of the subject in the memory. Further, the central processor is capable of executing the computer program instructions stored in the memory based on the calculated blood pressure value, and outputting a control signal for controlling the air pump and / or the air valve to the driving circuit.

[0088] According to a preferred embodiment, when measuring the blood pressure of the subject by using a blood pressure monitoring device based on the oscillometric method and / or the Korotkoff method, such as the second blood pressure acquisition device, the detection cuff is wrapped around the measurement site of the subject (e.g. the upper arm), and the blood pressure monitoring device is started by using the operation module and determining the corresponding detection task / action, so as to start the blood pressure measurement.

[0089] Specifically, the measurement task / action of the blood pressure usually includes a pressurization process and a depressurization process. In the pressurization process, the internal pressure of the air bag is increased by the air pump at a preset pressurization speed until the pressure is increased to a pressure threshold higher than the systolic blood pressure of the subject. In the depressurization process, the internal pressure of the air bag is gradually reduced from the pressure threshold by the air valve at a preset depressurization speed. In particular, the preset depressurization speed can be lower than the change rate of the internal pressure of the air bag in the pressurization process at the above-mentioned preset pressurization speed. In other words, the preset depressurization speed can be less than the preset pressurization speed.

[0090] According to a preferred embodiment, in the pressurization process, the central processor can determine the blood pressure value and / or the pulse rate of the subject based on the change of the internal pressure of the air bag when pressurizing at the above-mentioned preset pressurization speed. In the depressurization process, the central processor can determine the blood pressure value and / or the pulse rate of the subject based on the change of the internal pressure of the air bag when depressurizing at the above-mentioned preset depressurization speed.

[0091] According to a preferred embodiment, the central processor can further determine whether the blood pressure measurement value measured in the above-mentioned pressurization process is within a standard range. If the blood pressure measurement value measured in the above-mentioned pressurization process is within the standard range, the central processor further performs the processing of the blood pressure measurement value in the depressurization process.

[0092] According to a preferred embodiment, the second blood pressure acquisition device can be in signal connection with the first blood pressure acquisition device to acquire the physiological characteristic data acquired by the first blood pressure acquisition device. Alternatively, the second blood pressure acquisition device can also be in signal connection with other devices capable of independently acquiring the physiological characteristic data of the subject. Further, based on at least one item of physiological characteristic data of the subject, the second blood pressure acquisition device acquires a second blood pressure measurement value in a blood pressure state corresponding to or represented by the physiological characteristic data.

[0093] Example 2

[0094] The embodiment also provides a blood pressure management method, which can include the following steps:

[0095] S1: obtaining, by a first blood pressure collection device, a first blood pressure state measurement index associated with time and at least one physiological characteristic data associated with the first blood pressure state measurement index of a subject.

[0096] S2: determining, by a second blood pressure collection device, a blood pressure state matching the first blood pressure state measurement index based on the at least one physiological characteristic data, and obtaining a second blood pressure state measurement index in the blood pressure state.

[0097] S3: correcting, by a processor, the first blood pressure state measurement index obtained by the first blood pressure collection device based on the second blood pressure state measurement index determined by the second blood pressure collection device.

[0098] In particular, the at least one physiological characteristic data corresponding to the second blood pressure state measurement index obtained by the second blood pressure collection device at a certain time node or in a continuous time period is fitted with the at least one physiological characteristic data corresponding to the first blood pressure state measurement index determined by the first blood pressure collection device.

[0099] Optionally, the processor can be a processor of the first blood pressure collection device. Alternatively, the processor can be a processor of the second blood pressure collection device. Preferably, the processor can be a processor in a smart terminal. The first blood pressure collection device and the second blood pressure collection device can communicate with the smart terminal through a wireless communication mode.

[0100] The second blood pressure collection device based on the oscillometric method or the Korotkoff method is usually deployed in hospitals, clinics and other places, and generally needs to be supervised and guided by professionals to measure blood pressure. One of the advantages of such blood pressure monitoring devices is high detection accuracy, which is often used to accurately determine the blood pressure state of the subject. However, it has the defect that the subject needs to go to a professional place for detection, which is very inconvenient. In addition, such blood pressure collection devices usually need to bind the cuff to the measurement site (such as the arm) of the subject for a long time, combined with the long measurement time, which will cause the subject to feel uncomfortable and greatly reduce the subject's willingness to measure blood pressure. Therefore, the subject's enthusiasm for blood pressure measurement has decreased, which has become a major hidden danger for failing to discover unknown dangerous diseases suffered by the subject in time. Therefore, the prior art provides a portable blood pressure monitoring device (such as a smart wristwatch type first blood pressure collection device) that can measure blood pressure at any time. Such blood pressure collection devices are small in size, convenient to wear, and can be flexibly applied to blood pressure measurement in various time periods and occasions. In particular, such blood pressure monitoring devices usually also include detection of physiological data such as body temperature, heart rate and respiratory rate, thereby assisting in determining the blood pressure state of the subject.

[0101] Further, compared with the second blood pressure collection device based on the oscillometric method or the Korotkoff method, the accuracy of the portable blood pressure collection device is limited, and it is easily disturbed by external factors, so the blood pressure value measured by the portable blood pressure collection device has a large error. Therefore, when the measured person is in a home environment or other time and occasion that may involve blood pressure measurement, the blood pressure value measured by such a blood pressure collection device may have a large deviation, and based on the incorrect blood pressure measurement result, the health advice provided by such a blood pressure collection device to improve the blood pressure state, or even the blood pressure adjustment scheme provided is unreasonable. Therefore, the portable blood pressure collection device cannot provide a correct blood pressure measurement result, and even under the wrong health advice, it may even aggravate the adverse blood pressure change state of the measured person and increase the risk of disease.

[0102] According to a preferred embodiment, considering the detection defects of the portable blood pressure collection device, the present application uses a medical-grade blood pressure collection device with relatively high accuracy to correct the blood pressure measurement value obtained by the portable blood pressure collection device. Alternatively, the present application uses a medical-grade blood pressure collection device with relatively high accuracy to calibrate the blood pressure measurement value determined by the portable blood pressure collection device. Specifically, the blood pressure state of the user is determined by the portable blood pressure collection device, and the blood pressure state fitted with the blood pressure change curve determined by the portable blood pressure collection device is determined by the medical-grade blood pressure collection device or the physiological characteristic monitoring device coupled with the medical-grade blood pressure collection device. In addition, after determining the blood pressure state with high fitting degree with the blood pressure change curve obtained by the portable blood pressure collection device, the blood pressure measurement value determined by the portable blood pressure collection device is corrected by the blood pressure measurement value obtained by the medical-grade blood pressure collection device, including one or more of 24-hour average systolic pressure, average diastolic pressure, average pulse pressure, and basal blood pressure, to provide accurate blood pressure state measurement results to the user.

[0103] According to a preferred embodiment, the blood pressure measurement value determined by the portable blood pressure collection device is verified by the medical-grade blood pressure collection device, which can accurately determine the correctness of the blood pressure measurement value determined by the portable blood pressure collection device, and based on the determination of the accurate blood pressure value, it can provide guidance / advice on improving the blood pressure change state of the measured person.

[0104] Specifically, the measured person is in a place with a medical-grade blood pressure collection device, such as a hospital, and the first blood pressure collection device and the second blood pressure collection device are attached to the measurement site of the measured person to establish a detection connection with the measured person. Further, the first blood pressure collection device and the second blood pressure collection device are established for signal communication for interactive system data.

[0105] According to a preferred embodiment, the blood pressure of the subject is measured by both the first blood pressure acquisition device (portable blood pressure acquisition device) and the second blood pressure acquisition device (medical grade blood pressure acquisition device), and the blood pressure state fitted by the first blood pressure acquisition device is determined by the second blood pressure acquisition device. Specifically, the blood pressure state fitted by the first blood pressure acquisition device determined by the second blood pressure acquisition device can be one or more of the following conditions: the value or rate of change of one or more of the physiological characteristic data of the subject determined by both, such as the breathing rate, body temperature and heartbeat of the subject. Preferably, these physiological characteristic data are generally based on the detection data of the current subject at the same time as the reference benchmark.

[0106] According to a preferred embodiment, when the second blood pressure acquisition device determines at least one blood pressure state fitted by the blood pressure change curve determined by the first blood pressure acquisition device, the controller can correct the first blood pressure measurement value contained in the blood pressure state determined by the first blood pressure acquisition device or at least one blood pressure state evaluation index (such as 24-hour average systolic pressure, average diastolic pressure, average pulse pressure and basal blood pressure, etc.) related to the blood pressure state based on the second blood pressure measurement value determined by the second blood pressure acquisition device.

[0107] Thereafter, when the subject independently uses only the first blood pressure acquisition device (portable blood pressure acquisition device) to measure blood pressure at home or the like, the first blood pressure acquisition device will correct the current blood pressure measurement data based on the blood pressure state evaluation index in the same blood pressure state determined by the second blood pressure acquisition device (medical grade blood pressure acquisition device) as the reference value to obtain more accurate blood pressure state evaluation results. In other words, each of the measurement indexes in the blood pressure state evaluation results obtained by the first blood pressure acquisition device is corrected by the second blood pressure acquisition device.

[0108] According to a preferred embodiment, the blood pressure state measurement indexes of the subject are obtained by the second blood pressure acquisition device and the first blood pressure acquisition device, and the correction of one or more blood pressure state measurement indexes determined by the first blood pressure acquisition device by the blood pressure measurement results obtained by the second blood pressure acquisition device includes subjecting the subject to a plurality of different test cycles. Specifically, these test cycles are different at least in terms of test time (such as early morning, daytime, evening, or after intense exercise), test occasion (such as at home, outdoors, or other quiet or noisy places), etc. Thus, the differences in the blood pressure states that the subject can produce in different environments (including different occasions, physiological factors and external interference factors) and the blood pressure state measurement indexes in different test cycles can be determined.

[0109] According to a preferred embodiment, the blood pressure state metric indicators determined by the first blood pressure collection device can be corrected based on the blood pressure state metric indicators determined by the second blood pressure collection device, and the correction results can be fed back and stored in the first blood pressure collection device, so as to improve the detection accuracy of the first blood pressure collection device (portable blood pressure collection device). In particular, accurate blood pressure state determination results are helpful to verify the relationship between blood pressure state and recovery of patients with cardiovascular and cerebrovascular diseases and other diseases.

[0110] In particular, the correction of the first blood pressure state metric indicators determined by the first blood pressure collection device based on the second blood pressure state metric indicators determined by the second blood pressure collection device can be based on a preset correction program / algorithm, machine learning or setting of medical personnel. Alternatively, the second blood pressure state metric indicators determined by the medical-grade blood pressure collection device (such as the second blood pressure collection device) and the first blood pressure state metric indicators determined by the portable blood pressure collection device (such as the first blood pressure collection device) have corresponding functional relationships, which can come from a preset correction program / algorithm, machine learning or setting of medical personnel, and the corresponding relationship between the second blood pressure state metric indicators and the first blood pressure state metric indicators is usually pre-stored in a cloud server or a smart terminal, so that when the first blood pressure collection device determines the first blood pressure state metric indicators, the cloud or terminal processor can correct or calibrate the current first blood pressure state metric indicators through the corresponding second blood pressure state metric indicators.

[0111] According to a preferred embodiment, the blood pressure management method provided in the embodiment can further include:

[0112] The processor provides at least one guidance scheme related to the blood pressure state of the subject to the first blood pressure collection device based on the corrected first blood pressure state metric indicators. In particular, the guidance scheme related to the blood pressure state of the subject at least includes several guidance suggestions for improving the blood pressure change state of the subject. In particular, the corrected first blood pressure state metric indicators are determined by the second blood pressure state metric indicators determined by the second blood pressure collection device.

[0113] According to a preferred embodiment, the blood pressure state metric indicators of the portable blood pressure collection device are corrected by the blood pressure state metric indicators of the medical-grade blood pressure collection device, and the corresponding guidance scheme for improving the blood pressure state of the subject is formed according to the corrected blood pressure state metric indicators and stored in the portable blood pressure collection device (such as the first blood pressure collection device), so that the subject can obtain accurate blood pressure determination results at any time through the portable blood pressure collection device without the aid of the medical-grade blood pressure collection device, and execute more accurate and effective blood pressure improvement plans based on the guidance scheme provided thereby.

[0114] It is known that autonomic nerve disorder can cause low blood pressure. The autonomic nervous system refers to the peripheral nervous system, including sympathetic nerves and parasympathetic nerves, which work in coordination to enable the human body to function normally. The regulation of blood pressure depends on the heart and large blood vessels. The heart can contract normally to maintain a certain heart rate, and the large blood vessels can contract and expand at regular intervals to maintain blood pressure. When autonomic nerve function is disordered, the heart rate is abnormal, and the contraction and expansion of blood vessels are dysfunctional, which can easily cause blood pressure fluctuations. The most common is orthostatic hypotension, that is, the patient's blood pressure is normal when lying down, but when standing up, the heart rate cannot increase quickly, and the blood vessels cannot contract in time, causing blood to accumulate in the systemic circulation, resulting in low blood pressure. The autonomic nerve is a spinal nerve from the spinal cord, mainly distributed in the trunk and limbs, and is responsible for movement and sensation. The visceral nerve from the brain and spinal cord is mainly distributed in the internal organs and controls and coordinates the functions of internal organs, blood vessels and glands. Because it is not under the control of human will, it is called autonomic nerve, also known as vegetative nerve. Autonomic nerve reflex disorder (AD) or autonomic nerve reflex hyperactivity is a group of clinical syndromes characterized by paroxysmal sudden elevation of blood pressure caused by T6 spinal cord or above the plane of spinal cord injury (SCI).

[0115] In particular, the skin voltage (or resistance) of the human body is mainly related to the activity of sympathetic nerves and is less affected by temperature, and thus is selected as an index for evaluating the function of the sympathetic nervous system. In view of this, the present application also relates to detecting or using the change in the skin surface voltage (or resistance) of the user and / or the electrocardio signal and the blood pressure fluctuation value of the user to jointly evaluate the autonomic nerve function of the user, and further determine whether the user has a potential autonomic nerve disorder or autonomic nerve reflex disorder (AD). Specifically, the change in the skin surface voltage of the user can be obtained by a surface skin electrode. The surface skin electrode can be arranged in the manner of the detection electrode of the electrocardio acquisition module described above. Since the change in the skin voltage (or resistance) of the human body has a corresponding relationship with the autonomic nerve activity thereof, when the voltage (or resistance) or electrocardio signal of the skin surface of the user is obtained by the detection electrode, the autonomic nerve function of the user can be evaluated according to the synchronously obtained blood pressure fluctuation value. For example, when the blood pressure of the user is outside the normal blood pressure range, whether the change in the skin voltage (or resistance) or the electrocardio change of the user is in an inappropriate value, and whether the inappropriate value partially coincides with or intersects with the threshold interval in which the autonomic nerve dysfunction may exist, so as to determine whether the possible factors causing the significant abnormal change in the blood pressure of the user are related to the autonomic nerve dysfunction according to the blood pressure fluctuation value, the change in the skin surface voltage (or resistance) and / or the electrocardio signal of the user at the same time.
