[0041] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0042] The embodiment of the present invention provides an intelligent wearable monitoring system, such as Figure 1 Shown, including:

[0043] The smart vest 101 is worn on the patient and is used to collect the patient's heart rate, blood oxygen saturation, respiratory rate and lung sound data to obtain the patient's heart rate data, blood oxygen saturation data, respiratory rate and lung sound data;

[0044] The terminal device 102 is connected to the smart vest and is used to receive and transmit the patient's heart rate data, blood oxygen saturation data, respiratory rate data, and lung sound data;

[0045] The server 103 is connected to the terminal device 102 and is used to receive the patient's heart rate data, blood oxygen saturation data, respiratory rate data and lung sound data, and evaluate the patient's respiratory health status based on the patient's heart rate data, blood oxygen saturation data, respiratory rate data and lung sound data.

[0046] Common respiratory diseases include pneumonia, COPD, asthma, etc. If the patient's various physiological parameters can be effectively monitored in real time, home health management and early warning of respiratory diseases can be achieved.

[0047] In a specific embodiment, by providing a smart vest 101, the smart vest 101 can be set into an adult version and a children's version. Of course, it can also be customized into S size, M size and L size according to different types of versions, which is not limited here.

[0048] Specifically, the smart vest 101 is worn on the patient to collect various physiological parameters of the patient.

[0049] like Figure 2 As shown, the smart vest 101 includes:

[0050] Vest body 201;

[0051] The heart rate sensor 202 is provided on the inner side of the vest body 201 and faces the patient's chest area and is used to collect the patient's heart rate;

[0052] The blood oxygen saturation sensor 203 is provided in the interlayer of the vest body 201 and is connected to the blood oxygen saturation probe 204 via a cable. The blood oxygen saturation probe 204 is placed on the patient's finger to collect the patient's blood oxygen saturation;

[0053] The respiratory rate sensor 205 is provided on the inner side of the vest body 201, facing the chest and abdomen area of ​​the patient, and is used to collect the patient's respiratory rate;

[0054] The lung sound sensor 206 is disposed on the inner side of the vest body 201 , corresponding to the left and right lung areas of the patient, and is used to collect the patient's lung sounds.

[0055] First, the vest body 201 can be made of soft, breathable, skin-friendly material, and its design conforms to ergonomic curves to ensure wearing comfort. The vest body 201 can be disinfected and sterilized by ethylene oxide or ultraviolet irradiation for reuse.

[0056] Then, various sensors are arranged and set according to corresponding positions, and the surfaces of various sensors are coated with nanomaterials to improve sensing performance.

[0057] The heart rate sensor 202 is disposed in the precordial area of ​​the chest of the corresponding patient and can monitor the heart rate in real time using photoelectric sensor technology.

[0058] The blood oxygen saturation sensor 203 is connected to the blood oxygen saturation probe 204 via a cable. Specifically, the blood oxygen saturation probe 204 is placed on the patient's finger to collect the patient's blood oxygen saturation data, which is then transmitted to the blood oxygen saturation sensor via the cable for calculation and determination.

[0059] The respiratory rate sensor 205 includes a pressure sensor for detecting chest and abdominal movements, and a microprocessor for calculating the respiratory rate based on the movement. Specifically, the chest and abdominal movements over a period of time are detected and divided by the time to obtain the number of breaths per minute.

[0060] The lung sound sensor 206 is provided inside the vest body 201, corresponding to the lung areas on both sides, that is, two lung sound sensors 206 are provided, one corresponding to the left lung area and the other corresponding to the right lung area, for real-time collection of lung breathing sounds.

[0061] Next, the smart vest 101 also includes: a data transmission module 207, which is arranged on the inside of the vest body 201 and is respectively connected to the heart rate sensor 202, the blood oxygen saturation sensor 203, the respiratory rate sensor 205 and the lung sound sensor 206. The data sensor 207 is used to transmit the patient's heart rate data, blood oxygen saturation data, respiratory rate data and lung sound data.

[0062] Specifically, the data transmission module 207 transmits the data to the terminal device 102, which may be a mobile phone or a tablet, etc. The data transmission module 207 may be a Bluetooth or WIFI module, which is not limited here.

[0063] The terminal device 102 also only plays the role of data transmission. Therefore, after the data are transmitted to the server 103 via the terminal device 102, the server 103 effectively processes the data.

[0064] In addition, the vest body 201 is also provided with a voice alarm module 208, which issues an alarm based on the prompt information fed back by the terminal device 102, and a power module 209, which is used to power the various sensors, the voice alarm module 208, and the data transmission module 207. The vest body 201 is also provided with basic features such as pockets and zippers for easy wearing and use.

[0065] Specifically, the server 103 is used to:

[0066] Based on the patient's heart rate data, blood oxygen saturation data, respiratory rate data and lung sound data, the NEWS2 scoring standard is used to obtain the patient's respiratory health status assessment results; based on the patient's respiratory health status assessment results, a prompt message is sent to the terminal device.

[0067] Among them, in the NEWS2 scoring standard, specific values ​​are assigned to each type of data, and the respiratory health risk level is ultimately determined based on the assigned values.

[0068] Server 103 is specifically used for:

[0069] Based on the patient's heart rate data, blood oxygen saturation data, respiratory rate data and lung sound data, corresponding lung scores are assigned, and the scores are related to each data value; based on the scores, the total score results are obtained; based on the total score results and the respiratory health risk level table, the patient's respiratory health status assessment results are obtained.

[0070] For example, if the blood oxygen saturation data is less than 91%, it is assigned a score of 3, and if it is greater than 96%, it is assigned a score of 0. Each type of collected data can be assigned a score based on the current value. This results in a total score, which has a one-to-one correspondence with the respiratory health risk level table. According to the respiratory health risk level table, the corresponding respiratory health status score can be obtained.

[0071] For example, when the total score is between 0 and 4, it indicates that the respiratory health risk level is low risk; when the total score is greater than or equal to 7, it indicates that the respiratory health risk level is high risk.

[0072] The server 103 returns the final respiratory health status assessment result to the terminal device 102 so that the patient can view it.

[0073] Specifically, the server 103 can also be used to generate corresponding abnormal factor reminders based on the patient's respiratory health status assessment results and transmit them to the terminal device.

[0074] For example, a medium-risk diagnosis may indicate an early infection or a fluctuation in a chronic disease, requiring medical attention within 24 hours. A high-risk diagnosis may indicate a critical condition (such as heart failure or sepsis) requiring immediate emergency intervention.

[0075] In the above-mentioned risk assessment process, it is also necessary to conduct analysis in combination with the patient's age, underlying diseases and other conditions to improve the accuracy of the early warning.

[0076] Of course, the above feedback results can be evaluations performed at preset intervals. In addition, the type of respiratory disease can be predicted based on lung sound data.

[0077] Specifically, the server 103 is used to:

[0078] Obtain a diagnostic classification model; based on lung sound data and the diagnostic classification model, predict the patient's respiratory disease type.

[0079] In a specific embodiment, a large amount of lung sound data labeled with respiratory disease types is collected to train a prediction model, for example, using a CNN or RNN, to obtain the diagnostic classification model. The lung sound data includes both abnormal and normal data.

[0080] For example, abnormal lung sound data include dry rales and moist rales. Dry rales correspond to bronchial asthma and chronic obstructive pulmonary disease, while moist rales correspond to diseases such as pneumonia and pulmonary edema.

[0081] By predicting the type of respiratory disease based on a single piece of data, problems can be discovered early, thus improving the safety of monitoring.
