Description

Technical Field

[0001] The present disclosure relates to the technical field of health detection, and particularly relates to an intelligent wearable device and a detection method thereof. Background Art

[0002] At present, all tumor detection and monitoring methods can be divided into two categories. One is based on medical equipment provided in hospitals and clinics. This traditional medical model has deficiencies in both tumor detection and treatment. For high-risk patients, going to the hospital for treatment has problems such as high costs, inconvenience (most patients cannot regularly go to the hospital for medical treatment), and geographical restrictions (most patients cannot regularly go to the hospital for medical treatment). For low-risk patients, they will only go to the hospital for medical treatment after obvious symptoms appear. This passive medical model is difficult to achieve early detection and early treatment, and has a very high risk of missed diagnosis. That is, in the detection stage, usually only advanced severe patients will go to the hospital for examination on their own, which cannot achieve early detection and early treatment, and thus miss the best treatment opportunity. In the treatment stage, multiple and regular follow-up visits are necessary for effective treatment. However, this regular follow-up visit usually cannot be achieved due to various reasons.

[0080] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0081] In the embodiments of the present disclosure, the processing of collection, storage, use, processing, transmission, provision, and disclosure of the user's personal information complies with the provisions of relevant laws and regulations and does not violate public order and good customs.

[0082] Embodiment 1

[0083] In this embodiment, the target users wearing the intelligent wearable device are mainly: patients with initially diagnosed clinical ultrasound suggesting superficial suspicious lymph nodes but who cannot be clearly diagnosed for the time being, and postoperative tumor patients. Both types of patients need to regularly perform ultrasound reexaminations on superficial lymph nodes (for example, the examination interval is 3 - 6 months); however, due to the accessibility of existing medical resources and the compliance of patients, a large number of patients in clinical practice do not regularly go to the hospital for ultrasound reexaminations, which may lead to delays in the condition. Through the accurate, convenient, and highly consistent home and wearable intelligent wearable device in this embodiment, it can well dynamically monitor the changes of suspicious lymph nodes in the above patients and provide medical health guidance for the patients. Specifically,

[0084] As Figure 1 shown, the intelligent wearable device in this embodiment includes a shoulder strap main body structure 1, and a main controller 2 and an ultrasonic detection module 3 that are integrally arranged on the shoulder strap main body structure 1 and are communicatively connected. The position of the ultrasonic detection module 3 is set based on the position of the suspicious superficial lymph nodes on the target user's body;

[0085] For example, for postoperative tumor patients, by collecting the clinical pathological characteristics and ultrasonic information of the patient, the suspicious superficial lymph nodes corresponding to the target user are marked, and the position where the suspicious superficial lymph nodes are located is used as the position that needs to be tracked and detected by the intelligent wearable device in this embodiment to detect the corresponding lymph node status in real time and then detect the changes in a timely manner.

[0086] Generally speaking, an intelligent wearable device of a certain size type can be provided for target users of a certain gender; of course, for different target users, considering personal physical conditions, reminder differences, etc., there will be certain differences in the specific positions of the suspicious superficial lymph nodes. Therefore, the position of the ultrasonic detection module 3 can be designed specifically, that is, personalized settings can be realized to further ensure the rationality and accuracy of the final detection.

[0087] The ultrasonic detection module 3 is used to respond to the target user's completion of wearing the shoulder strap main structure 1, emit an ultrasonic detection signal to receive the actual ultrasonic feedback signal at the suspected superficial lymph nodes and send it to the main controller 2;

[0088] Specifically, the ultrasonic detection module 3 starts detection only after the user has worn it properly, avoiding detection deviation or even error caused by detection when the user is not wearing it correctly, ensuring the accuracy of subsequent detection; and it is not necessary to always enable the ultrasonic detection module 3 for detection. Detection is only started when necessary, achieving unnecessary power consumption, effectively reducing energy waste, and at the same time improving the service life of the smart wearable device.

[0089] The main controller 2 is used to extract the actual ultrasonic features in the actual ultrasonic feedback signal and obtain the actual state information of the lymph nodes at the suspected superficial lymph nodes based on the actual ultrasonic features; and / or obtain the physical state assessment information of the target user. The actual ultrasonic features include but are not limited to density features, thickness features, and size features.

[0090] Among them, research shows that almost all cancer occurrences are related to superficial lymph node swelling. For example, for specific malignant tumors (such as breast cancer and gastrointestinal cancer), the initial symptom of these diseases is superficial lymph node enlargement; therefore, by real-time tracking and detecting the actual state information of the lymph nodes at the suspected superficial lymph nodes, abnormalities can be detected in a timely manner so that the target user can take treatment in a timely manner, achieving early intervention and diagnosis, facilitating the doctor to conduct a full-process screening, treatment, and review, thereby effectively improving the timeliness and effectiveness of treatment.

[0091] In addition, it should be noted that the smart wearable device in this embodiment only plays a role of health reminder, detects and analyzes the changes of suspected lymph nodes, reminds the patient to seek medical attention in a timely manner, and mainly serves as reference information, and cannot completely replace clinical ultrasonic examination.

[0092] In this embodiment, a new type of intelligent wearable device for detecting the state of superficial lymph nodes based on ultrasonic detection is proposed. Specifically, the ultrasonic detection module 3 emits ultrasonic waves to obtain the ultrasonic feedback signal at the suspicious superficial lymph node, and analyzes and processes the extracted ultrasonic features to obtain information such as the actual state of the suspicious superficial lymph nodes on the target user and the evaluation of the physical state. That is, it can realize real-time tracking and detection of the state of the suspicious superficial lymph nodes on the target user, or perform detection at any time regularly or irregularly according to the preset detection rules, and timely, effectively, comprehensively and accurately detect the actual state information of the suspicious superficial lymph nodes on the target user at any detection moment, or detect the state changes at different detection moments, so as to inform the user in time, facilitate the user to take further treatment in time when necessary, and avoid the problems of inefficiency and lag in the procedure of completing relevant detections only when the user goes to the hospital, effectively ensuring the safety of the user and the convenience of operation, and improving the use experience; in addition, the intelligent wearable device also has the advantages of simple structure and easy operation.

[0093] Embodiment 2

[0094] As Figure 2 shown, the intelligent wearable device of this embodiment is a further improvement of Embodiment 1. Specifically:

[0095] In an implementable solution, the shoulder strap main structure 1 includes a first position detection module 4 integrally provided on the shoulder strap main structure 1 and communicatively connected to the main controller 2;

[0096] Among them, the first position detection module 4 is integrally provided on the ultrasonic detection module 3; or, the first position detection module 4 and the ultrasonic detection module 3 are integrally formed; the first position detection module 4 is a position detection sensor.

[0097] The first position detection module 4 is used to collect the actual position information of the ultrasonic detection module 3 and send it to the main controller 2;

[0098] The main controller 2 is used to generate and send a first prompt message indicating that the wearing is improper and needs to be adjusted in response to the first difference between the actual position information and the reference position information at the corresponding suspicious superficial lymph node being greater than or equal to the first preset value;

[0099] The main controller 2 is also used to generate and send a second prompt message indicating successful wearing in response to the first difference between the actual position information and the reference position information at the suspicious superficial lymph node being less than the first preset value.

[0100] Among them, the first prompt message and the second prompt message can be prompted through a prompt device provided on the shoulder strap main structure 1, and the prompt device includes but is not limited to a speaker and one or more prompt lights displaying different colors.

[0101] In the present disclosure, when the user wears the shoulder strap main structure 1, the position detection sensor timely detects whether the ultrasonic detection module 3 reaches the preset position. When the deviation from the preset position is large, a reminder will be issued to inform the user to adjust in time; when the deviation from the preset position is small, it is determined that the user has successfully worn the device. At this time, the ultrasonic detection module 3 can be driven to perform subsequent operations, avoiding detection deviations or even errors caused by detection when the user does not wear it correctly, ensuring the accuracy of subsequent detection; and the ultrasonic detection module 3 does not need to be always enabled for detection, and is only turned on when necessary, realizing unnecessary power consumption, effectively reducing energy waste, and improving the service life of the smart wearable device at the same time.

[0102] In an implementable solution, as Figure 3 shown, the shoulder strap main structure 1 includes a main structure and flexible shoulder strap structures respectively arranged on both sides of the main structure;

[0103] The shoulder strap main structure 1 includes a second position detection module 5 integrally arranged on the shoulder strap main structure 1 and communicatively connected to the main controller 2;

[0104] The second position detection module 5 includes a plurality of resistors, and the plurality of resistors are connected in series in sequence and are flexibly arranged near the outer edge on the inner side of the flexible shoulder strap structure.

[0105] Specifically, as Figure 4 shown, the second position detection module 5 is formed by a distributed series resistor circuit structure arranged on a strip-shaped flexible PCB (printed circuit board), where each square corresponds to a resistor R and is connected in series in sequence; the resistors at the front and rear ends are both electrically connected to the main controller 2.

[0106] The second position detection module 5 is used to collect the corresponding actual resistance value and send it to the main controller 2 in response to the target user wearing the flexible shoulder strap structure; wherein, the actual resistance value corresponds to the deformation state generated by the outer edge of the flexible shoulder strap structure when the target user wears it;

[0107] The main controller 2 is used to generate and send a third prompt message indicating that the wearing is improper and needs to be adjusted in response to the second difference between the actual resistance value and the reference resistance value being greater than or equal to the second preset value;

[0108] The main controller 2 is also used to generate and send a fourth prompt message indicating successful wearing in response to the second difference between the actual resistance value and the reference resistance value being less than the second preset value;

[0109] Among them, different target users have matching reference resistance values.

[0110] Specifically, before the user wears and uses it for the first time, the staff will perform an ultrasonic positioning in the hospital, and determine the reference resistance value corresponding to the user under correct wearing according to the ultrasonic positioning results and combined with the individual differences of the user; of course, a small number of users with special body types can customize the main structure of the shoulder strap 1 according to their body types.

[0111] In addition, when the user wears it for the first time, the staff will assist the user to wear it and tell the user how to adjust to quickly wear it to the correct position; the structure of the shoulder strap itself is simple and there is no special reexamination operation. After relevant guidance, most users can quickly adjust to the appropriate wearing position; in case of special circumstances, if the user cannot wear it correctly after wearing and adjusting at home for many times, they can first contact the follow-up staff through video call, and the follow-up staff will give remote answers. If the remote answers still cannot solve the corresponding problems, they can go to the user center for face-to-face solutions, so as to timely and effectively solve the problems encountered by the user during use, and improve the user experience.

[0112] In the present disclosure, when the user wears the main structure of the shoulder strap 1, the actual resistance value corresponding to the contact with the user is detected in time by a position detection device formed by several series connections. When the deviation from the reference resistance value is large, a reminder will be issued to inform the user to adjust in time; when the deviation from the reference resistance value is small, it is determined that the user has successfully worn it. At this time, the ultrasonic detection module 3 can be driven to perform subsequent operations, avoiding detection deviations or even errors caused by detection when the user is not wearing correctly, ensuring the accuracy of subsequent detection; and the ultrasonic detection module 3 does not need to be always enabled for detection, and is only turned on when necessary, realizing unnecessary power consumption, effectively reducing energy waste while increasing the service life of the smart wearable device.

[0113] In an implementable solution, most components such as the main controller 2 and the ultrasonic detection module 3 of the smart terminal device are integrally arranged on the same flexible PCB board, and are fixed in the flexible shoulder strap structure and located at a preset position; among them, the shape and specific setting position on the flexible PCB board can be designed or adjusted according to the actual situation.

[0114] Specifically, for example, as Figure 5 shown, the position A corresponds to the setting position of the flexible PCB board. After successful wearing, it is the position of the flexible PCB board corresponding to the armpit.

[0115] In an implementable solution, Figure 3 and Figure 5 the flexible shoulder strap structure is an adjustable structure; specifically, structures such as buckles (such as the position B in Figure 5 ) can be provided on the flexible shoulder strap structure to flexibly adjust the position, tightness, etc. of the contact with the user's body in the user's wearing state.

[0116] Among them, by changing the length and / or folding state of the shoulder strap, the deformation state of the flexible shoulder strap structure is adjusted to drive the actual resistance value collected by the second position detection module 5 for adjustment.

[0117] For adjusting the length of the shoulder strap, that is, it is adjusted by adjusting the buckle structure to make the shoulder strap longer or shorter; for adjusting the folding state, it is mainly considered that if the flexible shoulder strap structure contacts the user's body irregularly in a wrinkled folding manner during the wearing process, at this time, the folding state needs to be adjusted to ensure that the flexible shoulder strap structure is in a flat unfolded state and contacts the user's body, so as to ensure comfort during the subsequent wearing process of the user while ensuring successful wearing, and further improve the user's experience.

[0118] In an implementable solution, there are N suspicious superficial lymph nodes corresponding to different positions on the target user. The ultrasonic detection module 3 is an ultrasonic detection sensor, and the main controller 2 includes a microcontroller unit (MCU); the intelligent wearable device includes N ultrasonic detection sensors, and each suspicious superficial lymph node corresponds to an ultrasonic detection sensor; where N≥1 and is an integer.

[0119] The main controller 2 is used to extract the actual ultrasonic features in each actual ultrasonic feedback signal, and obtain the actual state information of the lymph nodes corresponding to each suspicious superficial lymph node based on each actual ultrasonic feature.

[0120] Or, determine the actual state information of the lymph nodes corresponding to each suspicious superficial lymph node based on each actual ultrasonic feature, and obtain the body state evaluation information of the target user according to the N actual state information.

[0121] In this solution, it is considered that not only can one suspicious superficial lymph node on the target user be detected, but also two or more suspicious superficial lymph nodes can be detected to synchronously realize real-time tracking and monitoring of multiple suspicious superficial lymph nodes, ensure timely and comprehensive information acquisition, facilitate the accuracy of subsequent comprehensive analysis and evaluation, and further ensure that abnormalities can be detected in time so that the target user can take treatment in time, achieving early intervention diagnosis and improving the effectiveness and reliability of treatment.

[0122] In an implementable solution, the intelligent wearable device further includes a signal processing module 6 integrally provided on the shoulder strap main structure 1 and connected between the main controller 2 and the ultrasonic detection module 3.

[0123] The signal processing module 6 is used to process the actual ultrasonic feedback signal sent by the ultrasonic detection module 3 and send the processed actual ultrasonic feedback signal to the main controller 2.

[0124] In this solution, by preprocessing the actual ultrasonic feedback signal, it can be directly subjected to relevant analysis and processing after being input into the main controller 2, ensuring the feasibility, reliability, and efficiency of data processing.

[0125] In an implementable solution, the smart wearable device further includes a power management module 7 and a power module 8 integrally provided on the shoulder strap main structure 1. The power management module 7 is connected between the main controller 2 and the power module 8, and the power management module 7 is used to drive and control the power module 8 based on the driving instruction sent by the main controller 2.

[0126] In this solution, the power module 8 is used to supply power to the smart wearable device; the power module 8 can be a wired charging module or a wireless charging module; the specific control of the working state of the power module 8 is realized through the power management module 7; that is, the smart wearable device is a device with a power supply function and portability.

[0127] In an implementable solution, the signal processing module 6 includes an ultrasonic converter 9, an analog-to-digital converter 10 (ADC), and a digital-to-analog converter 11 (DAC);

[0128] Among them, the ultrasonic detection module 3, the ultrasonic converter 9, the analog-to-digital converter 10, and the main controller 2 are sequentially communicatively connected, and the main controller 2, the digital-to-analog converter 11, the ultrasonic converter 9, and the ultrasonic detection module 3 are sequentially communicatively connected; the analog-to-digital converter 10, the digital-to-analog converter 11, and the ultrasonic converter 9 are all connected through a flexible connector;

[0129] In this disclosure, through the reasonable and ingenious design of these signal processing devices, the feasibility and reliability of data transmission are ensured.

[0130] In an implementable solution, the smart wearable device further includes a wireless communication module 12 communicatively connected to the main controller 2; among them, the wireless communication module 12 includes a Bluetooth module 13 and / or an antenna module 14;

[0131] In this disclosure, the smart wearable device communicates and interacts with other external devices through the Bluetooth module and the antenna module to receive or transmit data to meet the requirements of more data processing scenarios.

[0132] In an implementable solution, the smart wearable device communicates and interacts with the user terminal of the target user and / or other users outside at least one target user; specifically, it communicates and interacts with the application installed in the user terminal, and the application can run on user devices with operating systems such as Android, IOS (a mobile operating system), and Windows (an operating system).

[0133] In the present disclosure, the target user can view relevant data in the smart wearable device through their own user terminal. Of course, for other users who need to know the relevant data in the smart wearable device (such as other family members), they can establish an association with the smart wearable device through pre-authorization, so as to realize the synchronous sharing of the real-time detection information of the target user by multiple people, facilitating multiple people to jointly pay attention and jointly and timely make corresponding countermeasures, further ensuring that the target user can take treatment in time, achieving early intervention diagnosis and improving the timeliness and effectiveness of treatment. In this way, the needs of family co-attention are fully considered, and the user experience can be significantly improved.

[0134] Of course, according to actual needs, when the target user does not want some users to share their own detection information, they can apply to cancel the authorization of that user. Similarly, when the target user wants more users to share their own detection information, they can apply to authorize more users, that is, to realize dynamic and flexible sharing, further improving the user experience.

[0135] In an implementable solution, the smart wearable device further includes a data storage module 15 communicatively connected to the main controller 2.

[0136] In the present disclosure, all the data generated during the entire detection process of the smart wearable device can be stored in this data storage module for subsequent timely calling and viewing or further relevant processing. Of course, considering the occupation of the storage space of the data storage module, part of the data historically stored in the data storage module can be regularly backed up to the cloud server and deleted from it to ensure the smoothness and stability of data storage, and further ensure the stability and reliability of the overall operation of the smart wearable device.

[0137] In an implementable solution, the smart wearable device further includes a display 16 integrally provided on the shoulder strap main body structure 1 and communicatively connected to the main controller 2.

[0138] These above-mentioned signal processing modules 6 including ultrasonic transducers 9, analog-to-digital converters 10, digital-to-analog converters 11, Bluetooth modules, antenna modules, data storage modules, etc. can all be integrally arranged on the same PCB board.

[0139] In the present disclosure, a display can also be embedded at a set position on the outer surface of the shoulder strap main body structure 1 to display various working state data of the smart wearable device, and can also display the actual state information of the lymph nodes at each suspicious body surface lymph node of the target user, the change situation display diagram of the actual state information of the lymph nodes at the suspicious body surface lymph node in a certain detection stage, etc., for relevant personnel to view (such as the family members of the target user, doctors).

[0140] In addition, the smart wearable device in this embodiment performs a small-range precise detection based on the initial clinical ultrasound markers or the potential target areas of lymph node metastasis after tumor surgery. It does not need to be worn every day and can be worn according to the individual's physical condition needs to meet the detection requirement interface. For example, it is detected once every 10 - 14 days, and the wearable device is worn for 2 - 3 minutes each time. After marking the suspicious superficial lymph nodes, the smart wearable device is adjusted to ensure the relative consistency of the detection position each time, thereby ensuring the reliability of the continuous detection data. The detection results can form local health guidance opinions and will be uploaded to the cloud and synchronized to the doctor's client, etc., so that the attending doctor team can refer to the detection results and grasp the patient's condition changes in real time, etc., to achieve real-time detection and all-round guarantee of the detection effect.

[0141] Embodiment 3

[0142] The detection method of the smart wearable device in this embodiment is implemented by using the smart wearable device as described in Embodiment 1 or 2 above.

[0143] As Figure 6 shown, the detection method of the smart wearable device in this embodiment includes:

[0144] S101. In response to the target user completing the wearing of the shoulder strap main structure, an ultrasonic detection signal is sent to receive the actual ultrasonic feedback signal at the suspicious superficial lymph nodes.

[0145] Specifically, the ultrasonic detection module starts the detection only after the user wears it properly, avoiding detection deviation or even error caused by detection when the user is not wearing it correctly, and ensuring the accuracy of subsequent detection. And it is not necessary to always enable the ultrasonic detection module for detection. The detection is only started when necessary, realizing unnecessary power consumption, effectively reducing energy waste, and improving the service life of the smart wearable device at the same time.

[0146] S102. Extract the actual ultrasonic features from the actual ultrasonic feedback signal.

[0147] S103. Obtain the actual state information of the lymph nodes at the suspicious superficial lymph nodes based on the actual ultrasonic features; and / or obtain the body state assessment information of the target user.

[0148] Among them, research shows that almost all cancer occurrences are related to the swelling of superficial lymph nodes. For example, for specific malignant tumors (such as breast cancer, digestive tract cancer), the initial symptoms of these diseases are the swelling of superficial lymph nodes. Therefore, by real-time tracking and detecting the actual state information of the lymph nodes at the suspicious superficial lymph nodes, abnormalities can be detected in time so that the target user can take treatment in time, achieving early intervention diagnosis, facilitating the doctor to conduct a full-process screening, treatment, and review, and thus effectively improving the timeliness and effectiveness of treatment.

[0149] In this embodiment, a new type of intelligent wearable device for detecting the state of superficial lymph nodes based on ultrasonic detection is proposed. Specifically, the ultrasonic detection module emits ultrasonic waves to obtain the ultrasonic feedback signal at the suspected superficial lymph nodes, and analyzes and processes the extracted ultrasonic features to obtain information such as the actual state of the suspected superficial lymph nodes on the target user and the assessment of the physical state. That is, it can realize real-time tracking and detection of the state of the suspected superficial lymph nodes on the target user, or perform detection anytime and anywhere regularly or irregularly according to the preset detection rules, and timely, effectively, comprehensively and accurately detect the actual state information of the suspected superficial lymph nodes on the target user at any detection moment, or detect the state changes at different detection moments, so as to inform the user in time, facilitate the user to take further treatment in time when necessary, and avoid the problems of inefficiency and lag in the procedure of completing relevant detections only by going to the hospital, effectively ensuring the safety of the user and the convenience of operation, and improving the user experience.

[0150] Embodiment 4

[0151] The detection method of the intelligent wearable device in this embodiment is a further improvement of Embodiment 3. Specifically:

[0152] In an implementable solution, the shoulder strap main structure includes a first position detection module integrally provided on the shoulder strap main structure and communicatively connected to the main controller;

[0153] As Figure 7 shown, before step S101, it further includes:

[0154] S10011. Collect the actual position information of the ultrasonic detection module in the intelligent wearable device;

[0155] S10012. In response to the first difference between the actual position information and the reference position information at the corresponding suspected superficial lymph nodes being greater than or equal to the first preset value, generate and send a first prompt message indicating that the wearing is improper and needs to be adjusted;

[0156] In response to the first difference between the actual position information and the reference position information at the suspected superficial lymph nodes being less than the first preset value, generate and send a second prompt message indicating successful wearing, and execute step S101;

[0157] In the present disclosure, when a user wears the shoulder strap main structure, the position detection sensor timely detects whether the ultrasonic detection module reaches a preset position. When the deviation from the preset position is large, a reminder will be sent to inform the user to adjust in time; when the deviation from the preset position is small, it is determined that the user has worn it successfully. At this time, the ultrasonic detection module can be driven to perform subsequent operations, avoiding detection deviations or even errors caused by detection when the user does not wear it correctly, ensuring the accuracy of subsequent detection; and there is no need to always enable the ultrasonic detection module for detection. It is only turned on when necessary, realizing unnecessary power consumption, effectively reducing energy waste, and at the same time improving the service life of the smart wearable device.

[0158] In an implementable solution, the shoulder strap main structure of the smart wearable device includes a main structure and flexible shoulder strap structures respectively disposed on both sides of the main structure. The shoulder strap main structure includes a second position detection module integrally disposed on the shoulder strap main structure and communicatively connected to the main controller. The second position detection module 5 includes a plurality of resistors, and the plurality of resistors are connected in series in sequence and are flexibly arranged near the outer edge on the inner side of the flexible shoulder strap structure;

[0159] As Figure 8 shown, before step S101, it further includes:

[0160] S10021. In response to the target user wearing the flexible shoulder strap structure, collect the corresponding actual resistance value; wherein, the actual resistance value corresponds to the deformation state generated by the outer edge of the flexible shoulder strap structure when the target user wears it;

[0161] S10022. In response to the second difference between the actual resistance value and the reference resistance value being greater than or equal to the second preset value, generate and send a third prompt message indicating that the wearing is improper and needs to be adjusted;

[0162] In response to the second difference between the actual resistance value and the reference resistance value being less than the second preset value, generate and send a fourth prompt message indicating that the wearing is successful, and execute step S103;

[0163] Among them, different target users have matching reference resistance values.

[0164] In the present disclosure, when the user wears the main structure of the shoulder strap, the actual resistance value corresponding to the contact with the user is detected in a timely manner by a position detection device formed by a plurality of series connections. When the deviation from the reference resistance value is large, a reminder will be issued to inform the user to adjust in a timely manner; when the deviation from the reference resistance value is small, it is determined that the user has successfully worn the device. At this time, the ultrasonic detection module can be driven to perform subsequent operations, avoiding detection deviations or even errors caused by detection when the user is not wearing correctly, ensuring the accuracy of subsequent detection; and there is no need to always enable the ultrasonic detection module for detection. It is only turned on when necessary, achieving unnecessary power consumption, effectively reducing energy waste while increasing the service life of the smart wearable device.

[0165] In an implementable solution, step S103 includes:

[0166] S1031. Input the actual ultrasonic features into a pre-trained state prediction model to output a prediction result; wherein, the prediction result includes the actual state information of the lymph nodes at the suspicious superficial lymph nodes; and / or, the body state assessment information of the target user is predicted.

[0167] In the present disclosure, the feature data collected in real time is analyzed and processed based on a pre-trained state prediction model to output the actual state information of the lymph nodes at the suspicious superficial lymph nodes and the body state assessment information, that is, the artificial intelligence algorithm ensures the accuracy and efficiency of the detection result output.

[0168] In an implementable solution, the steps of training the state prediction model include:

[0169] Obtain a number of groups of sample training data for training;

[0170] Wherein, each group of sample training data includes a sample ultrasonic detection signal and a corresponding sample detection result, and the sample detection result includes the sample state information of the lymph nodes and / or the sample body state information;

[0171] The sample ultrasonic detection signal is obtained by a clinical ultrasonic imaging device and detected by a smart terminal device within a historical period; of course, as the data detected by the smart terminal device is updated, the data of the sample ultrasonic detection signal is also updated, and then the state prediction model is updated accordingly.

[0172] Extract sample ultrasonic features from the sample ultrasonic detection signal;

[0173] Use a preset screening method to screen out sample key features from the extracted sample ultrasonic features, and train a preset network model based on the sample key model and the corresponding sample detection result to obtain a state prediction model;

[0174] In the present disclosure, during the model training process, through the MRMR algorithm (Maximal Relevance and Minimal Redundancy algorithm) and the LASSO algorithm (Least Absolute Shrinkage and Selection Operator algorithm), the sample ultrasonic features in the extracted sample ultrasonic detection signals are initially dimensionally reduced and screened, and then the RFE method (Recursive Feature Elimination method) is further used for screening to obtain the sample key features; then, LDA (Linear Discriminant Analysis) is used to train a state prediction model (or a multi-modal ultrasonic radiomics prediction model) according to the sample key features and the corresponding sample detection results; and / or, a logistic regression classifier with LASSO constraint is used to train a state prediction model (or a clinical-multi-modal ultrasonic radiomics combined model) according to the sample key features and the corresponding sample detection results.

[0175] Among them, for the currently trained state prediction model, an ROC (Receiver Operating Characteristic curve) is plotted, and the AUC (Area Under the Curve) is calculated to evaluate the diagnostic performance of the model.

[0176] In an implementable solution, after step S103, it further includes:

[0177] Report the actual status information and / or body status evaluation information obtained every preset time period to the cloud server; the cloud server can be one or more, including but not limited to the clinical data collection center of the service hospital.

[0178] In this solution, by regularly or irregularly reporting the data detected by the intelligent wearable device to the cloud server, it is convenient for doctors to query all the reported data of the target user according to the basic information of the target user when the target user goes for an offline consultation, and use it as a reference to realize the whole-process screening, treatment, and reexamination of the user, effectively ensuring the reliability of the treatment; in addition, it is also convenient for doctors to conduct online consultations, comprehensively understand the actual situation of the target user, and thus give corresponding treatment plans, etc., further simplifying the consultation process and improving the user experience.

[0179] In an implementable solution, after step S103, it further includes:

[0180] Receive the actual examination results of the lymph nodes after each offline examination of the target user;

[0181] Compare the prediction result newly output by the currently trained state prediction model with the actual examination result to obtain a comparison result;

[0182] Update the currently trained state prediction model using the comparison result.

[0183] In this solution, the latest detection result detected by the smart wearable device is compared with the actual examination result to obtain the deviation therebetween, so as to correct the currently trained state prediction model, iteratively optimize the state prediction model, improve the prediction accuracy of the state prediction model, and then effectively ensure the accuracy of subsequent detection results, so as to effectively ensure the state detection of the target user, and achieve timely discovery of abnormalities and early intervention treatment.

[0184] In addition, it is also possible to recruit volunteers for baseline quantification, and at the same time, according to the follow-up situation of patients during use, the artificial intelligence model is iteratively updated in real time through Bayesian statistics.

[0185] Specifically, based on the feature data in the intelligent terminal device and the patient's condition data (including medical history, imaging, pathology and other data), prior data is formed through machine learning models such as the LASSO algorithm and Bayesian, and then these prior data are used to adjust the model so that the AUC curve corresponding to the state prediction model meets the standard; this operation is repeated to continuously optimize the model to obtain a state prediction model with higher output accuracy.

[0186] In an implementable solution, after step S103, it further includes:

[0187] In response to the actual state information and / or the body state assessment information meeting the preset abnormal conditions, generating an abnormal prompt information; and / or generating a matching intervention treatment strategy.

[0188] In the present disclosure, the output actual state information and body state assessment information can be further automatically analyzed and processed. When the preset abnormal conditions are met, an abnormal prompt information is generated to facilitate the target user to know in time and seek medical treatment in time or reasonably take corresponding countermeasures; even directly generate relevant information of the corresponding intervention treatment strategy, which can be broadcast by voice or the target user can view the corresponding intervention treatment strategy through the application program of the user terminal in time as an auxiliary reference, thereby further improving the user experience.

[0189] Although the specific implementation manners of the present disclosure have been described above, those skilled in the art should understand that these are only examples, and the protection scope of the present disclosure is defined by the appended claims. Without departing from the principle and essence of the present disclosure, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present disclosure.
