[0074] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.
[0075] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited to the specific embodiments disclosed below.
[0076] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or selectively excluded from other embodiments. Embodiment one
[0077] Reference Figure 1 For the first embodiment of the present application, the embodiment provides a patient real-time monitoring management system based on a smart wristband, comprising:
[0078] S1, analyzing the physiological indicators of the smart wristband.
[0079] In this embodiment, before developing a patient real-time monitoring management system based on a smart wristband, in-depth physiological indicator analysis is first needed. Through communication with medical experts, equipment manufacturers, and target users (patients), etc., the functions that the system needs to meet are determined. For example, the wristband needs to monitor physiological indicators such as heart rate, blood pressure, body temperature, and blood oxygen saturation in real time, and can issue an alarm in a timely manner when an anomaly occurs. In addition, it is also important to determine the goals of the system, for example, the system needs to have high-precision data acquisition capability, low-power design, powerful data analysis capability, and good user experience, etc. The requirement analysis stage should combine the characteristics of the target patient group, such as the elderly, chronic disease patients, etc., to ensure that the designed system can provide personalized health management services.
[0080] S2, physiological indicator analysis based on a smart wristband, selection of sensor types carried by the smart wristband.
[0081] In this embodiment, on the basis of physiological indicator analysis, it is crucial to select appropriate sensors. The wristband sensor needs to meet the requirements of high precision, low power consumption, and real-time performance, etc.
[0082] In steps S1 and S2, the physiological indicators of the smart wristband include heart rate, blood pressure, body temperature, and blood oxygen saturation, and the sensor types include heart rate sensors, blood pressure sensors, temperature sensors, and blood oxygen sensors.
[0083] For example, the heart rate sensor can be a sensor based on the photoplethysmography (PPG) technology, which can non-invasively measure heart rate and has relatively low power consumption. The data acquisition design should include the interface specification between the sensor and the smart wristband master chip.
[0084] S3, determination of the transmission path and communication protocol of the sensor data, to ensure real-time collection of data from the sensor to the cloud or local server.
[0085] In this embodiment, real-time transmission of data after collection is the key to ensuring that the system can intervene in a timely manner. The smart wristband needs to have stable wireless communication capability, and common communication methods include Bluetooth, Wi-Fi, LoRa, etc. According to the needs and use environment of the target patient group, the appropriate communication technology is selected. For example, Bluetooth is suitable for short-distance data transmission, Wi-Fi is suitable for scenarios that require real-time data transmission, and LoRa is suitable for long-distance and low-power application scenarios.
[0086] In addition, the communication protocol design should consider the reliability of data transmission, using lightweight protocols such as MQTT or CoAP to ensure smooth data transmission in various network environments. This step also needs to consider the battery life of the device, so it is necessary to optimize the frequency of data transmission and the size of the data packet, balancing the relationship between real-time performance and battery consumption.
[0087] S4, based on real-time collected sensor data, abnormality detection and early warning are performed.
[0088] Abnormality detection is one of the core functions of the system. In order to timely discover possible health problems of the patient, such as cardiac arrest and difficulty breathing, the system needs to design a model to analyze data in real time and make judgments.
[0089] In this embodiment, an abnormality detection and early warning model is constructed, which combines various physiological indicators and individual differences of the patient to perform abnormality detection and intelligent early warning.
[0090] Define the physiological indicators monitored by the intelligent wristband:
[0091] Heart rate , blood oxygen saturation , blood pressure , body temperature Therefore:
[0092] represents the physiological indicator data collected at time point
[0093] represents the physiological indicator data sequence in the past period of time.
[0094] The abnormality detection and early warning model comprises:
[0095] Weighted abnormality score
[0096] Overall abnormality score
[0097] Dynamic adjustment of threshold value
[0098] Triggering of early warning mechanism
[0099] Further, when performing the weighted abnormality score, the abnormality score of each physiological indicator is defined as as follows:
[0100]
[0101] wherein,
[0102] is the first a value of a physiological indicator (e.g. heart rate, blood oxygen, etc.);
[0103] and are the mean and standard deviation of the physiological indicator in the patient's historical data, representing the normal fluctuation range;
[0104] is the weight coefficient of the indicator, used to represent the importance of different indicators. Different physiological indicators are more sensitive to the warning of certain health risks, so their weight coefficients are different.
[0105] The overall abnormal score is obtained by weighted average of the abnormal scores of all physiological indicators
[0106]
[0107] wherein,
[0108] is the number of monitored physiological indicators;
[0109] The overall abnormal score is used to measure the abnormality of each physiological indicator at the current time.
[0110] In order to consider the individual differences and health history of the patient, since the health baseline of different patients is quite different, a dynamic adjustment threshold is introduced to avoid false alarms and ensure the accuracy of the warning, and the calculation method of the dynamic adjustment threshold is as follows:
[0111]
[0112] wherein,
[0113] is the basic threshold, determined based on the statistical characteristics of all patient data;
[0114] is an adjustment coefficient, representing the sensitivity of the model to the dynamic adjustment threshold, which is fine-tuned according to the patient's health history;
[0115] is the overall abnormal score at the previous time, and the threshold is dynamically adjusted according to the abnormal score at the previous time.
[0116] If the overall abnormal score exceeds the threshold , it is determined to be abnormal, triggering the warning mechanism, and the warning signal will be immediately pushed to the patient or medical personnel through the intelligent device or mobile application;
[0117] The urgency of the warning is determined according to The size of the value is graded, if the value above the threshold is high, an emergency alarm is sent out; if the value above the threshold is low, a normal alarm is sent out.
[0118] When the model is used, after a new round of data is obtained from the wristband each time, the system calculates the abnormal scores of each physiological indicator , and updates the overall abnormal score . The system dynamically adjusts the sensitivity of the early warning according to the patient's historical data and real-time health status, ensuring that there are not too many false alarms. Once the set threshold is exceeded, the system triggers an early warning to notify the patient or medical personnel, ensuring timely intervention.
[0119] The model can be adjusted according to the individual differences of patients to avoid false alarms and improve the accuracy of early warnings, and is a key component of the intelligent wristband patient real-time monitoring and management system.
[0120] S5, based on real-time collected sensor data, analyze the patient's long-term health data and living habits, establish a personalized health trend model, and predict the future health status of the patient wearing the intelligent wristband.
[0121] In this embodiment, the health trend model dynamically correlates the physiological indicators: heart rate , blood oxygen saturation , blood pressure , body temperature with the patient's health history to form a personalized health trend and predict the health status at a certain time in the future.
[0122] Further, the health trend model defines the historical data of each physiological indicator as:
[0123] the heart rate, blood pressure, blood oxygen saturation and body temperature at time ;
[0124] the weight coefficient of each physiological indicator at time , which is dynamically adjusted according to the individual situation of each patient (such as health status, medical history, etc.).
[0125] The future health status is predicted by weighting the historical data :
[0126] ;
[0127] wherein,
[0128] represents the predicted health status;
[0129] Indicates the first The change in a physiological indicator, that is, the change compared to the previous day;
[0130] It is a moment Corresponding physiological indicators The weights;
[0131] It is a moderating coefficient that controls the impact of changes on predicted health status, used to adjust the degree of influence of the trend of change.
[0132] In the aforementioned health trend model, the weights Dynamic adjustments are made to make the impact of each physiological indicator on health prediction more flexible and personalized; the weight of each physiological indicator is automatically adjusted based on historical health data and real-time monitoring feedback to adapt to changes in the patient's health. For example, during certain special periods (such as in the pre-heart attack phase for patients with heart disease), the weight of heart rate may be higher than usual.
[0133] The formula for dynamically adjusting the weights is as follows:
[0134] ;
[0135] in,
[0136] For a moment Corresponding physiological indicators The weights;
[0137] It is a measure of error in the prediction results, usually expressed as the difference between the model's predicted value and the actual value. Specifically, if the deviation in predicting health status is large, it indicates that the influence of that physiological indicator on the current prediction may need to be increased;
[0138] It is the learning rate of each physiological indicator, used to control the sensitivity of weight updates.
[0139] When in use, the model collects the patient's health data (heart rate, blood pressure, blood oxygen, body temperature, etc.) and environmental information (such as activity level, sleep status, etc.) from the smart wristband and other sensors. The model is trained using the patient's historical health data to obtain the initial weights for each physiological indicator. The system continuously monitors patients' health status using devices such as wristbands, and predicts future health status based on historical and real-time data. Weighting coefficients are adjusted according to real-time data and error feedback. Optimize prediction accuracy. Use the model to predict health status at a future point in time. and determine whether it exceeds the health risk threshold, thereby triggering an early warning.
[0140] According to the historical health data and real-time data of the individual patient, the weights of various physiological indicators are dynamically adjusted, and the future health trend is predicted. In this way, the system can not only identify sudden health problems in time, but also provide a scientific basis for long-term health management, and realize more personalized health prediction and early warning.
