As the name suggests, electronic smart bandages not only have the basic functions of traditional bandages, namely protecting wounds, preventing infection, and promoting healing, but also have more intelligent features, bringing patients a more convenient and efficient medical experience.

[0004] However, electronic smart bandages still face many challenges and problems to be solved at the current stage.

[0033] Where BP is blood pressure, g is the function model trained based on experimental data;

[0034] Finally, the initial pressure value Pin is the weighted sum of the basic pressure value Px and the dynamically adjusted pressure value Pd, and the calculation formula is:

[0049] Wherein, Pout(t) is the output pressure value at time t, and Pout(t+1) is the output pressure value at time t+1.

[0066] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0067] See also Figure 1 This embodiment proposes a multi-purpose segmented easy-to-wear electronic smart bandage, including:

[0068] Inguinal bandage, thigh bandage 4 and calf bandage;

[0069] Wherein, a pressurizer 3 is arranged in the inguinal bandage; a blood vessel pulsation sensing element is arranged in the pressurizer 3;

[0070] The groin bandage is detachably connected to the thigh bandage 4 via Velcro, and the thigh bandage 4 is detachably connected to the calf bandage via Velcro;

[0071] The inguinal bandage comprises an oblique bandage 2 and a transverse bandage 1, wherein the oblique bandage 2 and the transverse bandage 1 are combined to form a complete compression surface between the anterior superior iliac spine and the pubic bone;

[0072] The inguinal bandage is used for pressurizing arterial / venous puncture points; the thigh bandage 4 or the calf bandage is used for pressurizing varicose veins.

[0073] It is understandable that this embodiment proposes a segmented wearable electronic intelligent bandage with multiple uses. The design of this bandage is very user-friendly and can be flexibly applied to different medical occasions. It mainly consists of three parts, namely, the groin segment bandage, the thigh segment bandage 4 and the calf segment bandage. These bandages are connected by Velcro, which can be easily disassembled and can ensure tight fixation and will not fall off easily.

[0074] On the inner side of the inguinal bandage, we set a pressurizer 3. The pressurizer 3 is equipped with a vascular pulsation sensing element, which can accurately capture the pulsation of the blood vessels. In this way, the doctor can adjust the bandage appropriately according to the patient's specific condition to achieve the best treatment effect.

[0075] It is worth mentioning that the design of the inguinal bandage is very unique. It includes an oblique bandage 2 and a transverse bandage 1, which are combined between the anterior superior iliac spine and the pubic bone to form a complete compression surface. Such a design can ensure uniform compression and effectively reduce the discomfort caused by compression.

[0076] In addition, the bandage in this embodiment has multiple application scenarios. The inguinal bandage is mainly used to pressurize the arterial / venous puncture point to prevent bleeding and infection. The thigh bandage 4 and the calf bandage are mainly used for pressurization treatment of varicose veins. In this way, the doctor can choose the appropriate bandage for treatment according to the patient's specific condition, which greatly improves the pertinence and effect of the treatment.

[0077] In addition, the multi-purpose segmented easy-to-wear electronic smart bandage proposed in this embodiment also has the function of medical elastic stockings in the design of the calf and thigh parts, which makes it excellent in treating varicose veins. It can be used for preoperative treatment and pressure bandage after surgery to promote recovery. This unique design concept allows the bandage to better fit the anatomical structure of the human body, thereby providing a more effective treatment effect, which is very rare in the current medical field.

[0078] The two main components of the bandage are connected by Velcro, which greatly simplifies the wearing process and allows users to wear it easily and quickly. In addition, the opening of the bandage is designed as a side opening, which is also connected by Velcro, which not only makes it more convenient to wear, but also improves the comfort to a certain extent. This design allows users to easily wear it by themselves, and also improves the comfort during the wearing process.

[0079] In general, the design of this multi-purpose segmented easy-to-wear electronic smart bandage has shown its high clinical application value both from a practical and humanistic perspective. The proposal of this design concept not only brings new possibilities to the medical field, but also brings a better treatment experience to patients.

[0080] In some embodiments of the present application, the shape formed by the combination of the oblique bandage 2 and the transverse bandage 1 is a V-shaped structure;

[0081] The tip of the V-shaped structure points to the center of the inguinal region, so that the oblique bandage 2 and the transverse bandage 1 form a complete compression surface between the anterior superior iliac spine and the pubic bone.

[0082] It is understandable that the combined part of the oblique bandage 2 and the transverse bandage 1 of this embodiment will form an obvious V-shaped structure; the sharp part of this V-shaped structure is facing the center of the inguinal area. Such a design enables the oblique bandage 2 and the transverse bandage 1 to cooperate effectively to form a comprehensive and solid compression surface in the area between the anterior superior iliac spine and the pubic bone. This compression surface can not only provide uniform pressure to support and support the relevant body parts, but also enhance the stability and comfort of the part of the bandage that contacts the body through this unique V-shaped structural design. In addition, the characteristic that the tip of the V-shaped structure points to the center of the inguinal area helps to more accurately locate the area that needs support or fixation when applying pressure, thereby optimizing the effect of the treatment or recovery process.

[0083] In some embodiments of the present application, a control module is provided inside the pressurizer 3;

[0084] The control module is used to control the pressurizer 3 to apply pressure to the inguinal bandage; at the same time, the control module is also used to adjust the output pressure of the pressurizer 3 according to the vascular pulsation information fed back by the vascular pulsation sensing element.

[0085] It is understandable that the present embodiment designs a pressurizer 3 system including a control module; the main function of the control module is to control the pressurizer 3 to accurately apply pressure to the bandage of the inguinal segment. In this process, the role of the control module is not only to simply control the operation of the pressurizer 3, it also undertakes the important task of adjusting the output pressure of the pressurizer 3 in real time according to the vascular pulsation information collected from the vascular pulsation sensing element. Such a design enables the pressurizer 3 to respond to changes in vascular pulsation more intelligently and flexibly, thereby ensuring that the pressure applied by the bandage can achieve a therapeutic effect without causing discomfort to the patient. This method of applying bandage pressure by intelligently adjusting the pressure not only improves the effectiveness of the treatment, but also greatly improves the comfort of the patient.

[0086] In some embodiments of the present application, when the control module is used to control the pressurizer 3 to apply pressure to the inguinal bandage; and the control module is also used to adjust the output pressure of the pressurizer 3 according to the vascular pulsation information fed back by the vascular pulsation sensing element, the following steps are included:

[0087] Obtain the user's basic information, physiological parameters and surgery-related information;

[0088] The control module is configured to calculate an initial pressure value suitable for the current user according to a preset calculation formula using the basic information and physiological parameters;

[0089] The control module is further configured to adjust the initial pressure value using surgery-related information to obtain an applied pressure value;

[0090] Among them, the basic information includes age, weight and height; the physiological parameters include heart rate, blood pressure, vascular pulsation intensity and basic resting pressure; the surgery-related information includes puncture point location, puncture point depth and hematoma information.

[0091] It is understandable that the main function of the control module in this embodiment is to control the pressurizer 3 to apply appropriate pressure to the bandage of the inguinal segment. At the same time, the control module also needs to adjust the output pressure of the pressurizer 3 in real time according to the vascular pulsation information fed back by the vascular pulsation sensing element. This process mainly includes the following steps:

[0092] First, it is necessary to obtain the user's basic information, physiological parameters, and surgery-related information. This information is crucial for the control module to calculate the initial pressure value suitable for the current user.

[0093] Secondly, the control module will use the user's basic information and physiological parameters to calculate the initial pressure value suitable for the current user according to the preset calculation formula. This step ensures the personalized setting of the pressure value to meet the needs of different users.

[0094] Next, the control module will also adjust the initial pressure value using the surgery-related information to obtain the applied pressure value. This step makes the pressure value more accurate and can better adapt to changes during the surgery.

[0095] Here, it should be particularly pointed out that the basic information includes age, weight and height; the physiological parameters include heart rate, blood pressure, vascular pulsation intensity and basic resting pressure; the surgery-related information includes puncture point location, puncture point depth and hematoma information. The acquisition and use of this information are all to ensure that the pressurizer 3 can apply the most appropriate pressure according to the actual situation of the user.

[0096] In general, these embodiments demonstrate how the control module calculates and adjusts the initial pressure value based on the user's personal information and physiological parameters, as well as surgery-related information, to achieve precise control of the output pressure of the pressurizer 3 .

[0097] In some embodiments of the present application, before calculating the initial pressure value suitable for the current user according to a preset calculation formula, the user's basic information, physiological parameters and surgery-related information are processed, and the data processing includes:

[0098] After standardization of age, heart rate, and vascular pulsation strength, they were recorded as Age, HR, and BN, respectively;

[0099] After normalization, weight, height, and puncture point depth were recorded as Wei, Hei, and Lo, respectively;

[0100] After one-hot encoding of the puncture point position, it is recorded as Bin;

[0101] The hematoma information is converted into a binary parameter. When a hematoma exists, the hematoma information is recorded as 1, and when a hematoma does not exist, the hematoma information is recorded as 0.

[0102] It is understandable that in order to obtain an initial pressure value that meets the needs of a specific user, this embodiment first applies a set of predefined calculation formulas. In this process, the user's basic information, physiological parameters, and surgery-related data are comprehensively processed. This data processing includes but is not limited to the following aspects:

[0103] First, the user's age, heart rate, and vascular pulsation strength are standardized to eliminate the impact of physiological differences between individuals. After standardization, these data are represented by Age, HR, and BN. Standardization is intended to convert such physiological parameters into values ​​that can be directly compared, thereby improving the accuracy and reliability of subsequent calculations.

[0104] Secondly, in order to eliminate the influence of body shape differences between individuals, the weight and height data will be normalized. After this conversion, the weight and height data will no longer be affected by individual differences, making the calculation results more universally applicable. The normalized data are represented by Wei and Hei respectively.

[0105] Furthermore, the one-hot encoding method is used to process the location information of the puncture point. This encoding method can represent the location information of the puncture point in binary form, so that the location information can be accurately identified and processed by the computer system in subsequent calculations. After one-hot encoding, the puncture point location information is represented by Bin.

[0106] Finally, the hematoma information is processed using a binary parameter conversion method. Specifically, if a hematoma exists, the hematoma information will be marked as 1; if a hematoma does not exist, the hematoma information will be marked as 0. This processing method simplifies the expression of hematoma information and facilitates the judgment of the hematoma situation during the calculation process.

[0107] By comprehensively processing the above data, a more accurate and personalized initial pressure value can be provided to the user, thereby improving the safety and effectiveness of the operation. These processing methods not only ensure the accuracy of the data and the convenience of calculation, but also make the present invention have a wide range of application prospects.

[0108] In some embodiments of the present application, the control module is configured to use the basic information and physiological parameters to calculate an initial pressure value suitable for the current user according to a preset calculation formula, including:

[0109] The basic pressure value Px is calculated based on age, weight, height and basic resting pressure. The calculation formula is:

[0110] Px=f(Age,Wei,Hei,P0);

[0111] Among them, P0 is the basic resting state pressure, and f is the function model trained based on experimental data;

[0112] The control module also uses heart rate, blood pressure and vascular pulsation intensity to dynamically adjust the basic pressure value Px to obtain a dynamically adjusted pressure value Pd, and the calculation formula is:

[0113] Pd=g(Px,HR,BP,BN);

[0114] Where BP is blood pressure, g is the function model trained based on experimental data;

[0115] Finally, the initial pressure value Pin is the weighted sum of the basic pressure value Px and the dynamically adjusted pressure value Pd, and the calculation formula is:

[0116] Pin = α*Px + β*Pd;

[0117] Among them, α and β are weight coefficients, and α+β=1;

[0118] Among them, the basic function models of f and g are polynomial regression models.

[0119] It is understandable that this embodiment further introduces the user's historical usage data and feedback system to further optimize the calculation of the initial pressure value. Specifically, the control module is not only based on the user's basic information and real-time physiological parameters, but also combines the user's pressure usage records and feedback scores over a period of time to build a more personalized pressure adjustment algorithm.

[0120] The user's historical usage data includes the user's preference for pressure values ​​in different time periods, adjustment frequency, and final satisfaction score, etc. These data are stored in the database and analyzed by machine learning algorithms to extract the user's pressure preference pattern.

[0121] After the control module calculates the basic pressure value Px and the dynamically adjusted pressure value Pd, it will further compare and match these values ​​with the user's historical usage data. If the system finds that the user's current state matches the pressure preference in a similar state in the past, the control module will tend to select the pressure value in that state as a reference for the initial pressure value Pin.

[0122] In addition, in order to better meet the personalized needs of different users, we have also introduced a user feedback mechanism. Users can evaluate the current pressure value in real time during use, such as by scoring or providing text feedback. These feedback data will be collected in real time and used to adjust the parameters of the function models f and g, thereby gradually optimizing the calculated initial pressure value Pin to make it more in line with the actual needs of users.

[0123] In this way, the system of this embodiment can not only calculate the initial pressure value suitable for the current user based on the user's basic information and real-time physiological parameters, but also continuously optimize and adjust this value through historical usage data and user feedback to make it more in line with the user's personalized needs. This not only improves the accuracy and adaptability of the system, but also improves the user's experience and satisfaction.

[0124] In some embodiments of the present application, the method for determining the weighting coefficients α and β includes:

[0125] Use linear regression, random forest or neural network to train the experiment and obtain several α and β values;

[0126] Through cross-validation and performance evaluation, a set of α and β values ​​with optimal performance are determined and used as weight coefficients for calculating the initial pressure value in the control module.

[0127] It is understandable that in order to accurately determine the weighting coefficients α and β, the method adopted in this embodiment involves a variety of machine learning techniques. First, the linear regression method in statistics is used to train the experimental data by building a model to obtain a series of α and β values. Then, a random forest algorithm is used, which improves the accuracy of prediction by building multiple decision trees and voting, and is also used to train the model and obtain a set of α and β values. In addition, a neural network is also used, which is a computational model that imitates the structure of neurons in the human brain, and optimizes the values ​​of α and β by learning data features.

[0128] After obtaining multiple α and β values, a cross-validation method is implemented to select the coefficient combination with the best performance. Cross-validation is a method for evaluating the robustness of a model by splitting the dataset into multiple subsets and using a different subset as a validation set in each iteration to ensure the generalization ability of the model. After each validation, the performance of the model is evaluated, which usually involves calculating the prediction error or related performance indicators.

[0129] In this way, a set of α and β values ​​can be determined so that the model achieves the best performance in predicting the initial pressure value. This set of optimal α and β values ​​will be applied to the control module to calculate the initial pressure value, thereby improving the accuracy and efficiency of the entire system. Such an embodiment shows how to automatically determine the optimal weight coefficients by combining different machine learning techniques and evaluation methods, thereby improving the overall performance of the algorithm.

[0130] In some embodiments of the present application, the control module is further used to adjust the output pressure of the pressurizer 3 according to the vascular pulsation information fed back by the vascular pulsation sensing element, including:

[0131] The control module adjusts the initial pressure value Pin according to the physiological parameters obtained in real time and the vascular pulsation information fed back by the vascular pulsation sensing element to adjust the output pressure of the pressurizer 3; the adjustment method and adjustment formula include:

[0132] The heart rate, blood pressure and vascular pulsation strength of the current user are obtained in real time, and the real-time adjustment factor R is calculated through a preset dynamic adjustment function h; wherein h is a dynamic adjustment function model obtained by training based on experimental data;

[0133] R=h(HRrea l,BPrea l,BNrea l,…);

[0134] The initial pressure value Pin is corrected using the real-time adjustment factor R to obtain the final output pressure value Pout, and the formula is as follows:

[0135] Pout=Pi n+γ*R;

[0136] Among them, γ is the adjustment coefficient, which is used to control the influence of the adjustment factor. The value of γ is determined by experimental data and performance evaluation;

[0137] The control module continuously monitors the vascular pulsation information fed back by the vascular pulsation sensing element and the real-time physiological parameters; dynamically adjusts the output pressure value according to the feedback information, and the dynamic adjustment process is: Pout(t+1)=Pout(t)+γ*(h(HRrea l(t),BPrea l(t),BNrea l(t),…)-Pout(t));

[0138] Wherein, Pout(t) is the output pressure value at time t, and Pout(t+1) is the output pressure value at time t+1.

[0139] It is understandable that the functions of the control module involved in this embodiment have been further enriched and refined. The main responsibility of the control module is not only to simply process the signals from the vascular pulsation sensing element, but also to accurately adjust the output pressure of the pressurizer 3 according to these signals and the physiological parameters collected in real time. This adjustment process is highly intelligent, which ensures that the pressurizer 3 can adapt to the subtle changes in vascular pulsation under different conditions, thereby providing a more accurate and adaptable treatment plan.

[0140] The workflow of the control module includes a series of delicate steps. First, it collects the user's heart rate, blood pressure, and blood vessel pulsation intensity in real time, which are essential for adjusting the output pressure of the pressurizer 3. Then, these physiological parameters are converted into a real-time adjustment factor R through a pre-set dynamic adjustment function h. It should be pointed out that this dynamic adjustment function h is obtained through training with a large amount of experimental data, and it can accurately reflect the impact of changes in different physiological parameters on blood vessel pulsation.

[0141] After that, the control module uses this real-time adjustment factor R to correct the initial pressure value Pin, so as to obtain a more appropriate output pressure value Pout. Here, γ is an adjustment coefficient, which plays a role in controlling the influence of R. The value of γ is determined through detailed experimental data analysis and performance evaluation, ensuring the stability and reliability of the adjustment process.

[0142] The control module will also continuously monitor the information fed back by the vascular pulsation sensing element and the real-time physiological parameters, and continuously dynamically adjust the output pressure value. In this dynamic adjustment process, Pout(t) represents the output pressure value at time t, and Pout(t+1) represents the output pressure value at time t+1. Through such continuous adjustment, the control module can ensure the real-time and adaptability of the output pressure of the pressurizer 3, providing users with a more accurate and personalized treatment experience.

[0143] In some embodiments of the present application, the multi-purpose segmented easy-to-wear electronic smart bandage further includes:

[0144] A communication module, connected to the control module and an external device respectively;

[0145] The communication module is used to send the data collected by the control module to the external device and receive the control instructions of the external device.

[0146] It is understandable that the multifunctional segmented wearable electronic smart bandage proposed in this embodiment is further equipped with advanced communication modules. These communication modules are carefully designed to achieve seamless connection with the control module and external devices. Specifically, these communication interfaces are connected to the control module and the external device respectively through a stable connection.

[0147] The main function of the communication module is to be responsible for two-way data transmission. On the one hand, it can send various data collected by the control module, including but not limited to sensor readings, environmental information, user's health status, etc., to external devices. In this way, medical professionals or users themselves can monitor the status of the bandage in real time to ensure its normal operation and obtain important treatment or care information in a timely manner.

[0148] On the other hand, the communication module is also responsible for receiving control instructions from external devices. These instructions may involve adjusting the tightness of the bandage, changing the working mode, updating the software program, etc. By receiving these instructions, the bandage can respond and adjust accordingly according to the needs of the external device or the user, thereby providing more personalized and accurate treatment or auxiliary services.

[0149] Through this design, the multi-purpose segmented easy-to-wear electronic smart bandage in this application can not only independently complete a series of complex monitoring and treatment tasks, but also effectively exchange information with external devices through the communication module, greatly expanding its functionality and application scope. This smart bandage has great potential and broad application prospects in the fields of medical care, rehabilitation assistance, and daily health monitoring.

[0150] In some embodiments of the present application, the multi-purpose segmented easy-to-wear electronic smart bandage further includes:

[0151] An alarm element connected to the control module; the alarm element is configured to send an alarm signal when an abnormal situation is detected;

[0152] The abnormal conditions include abnormal blood vessel pulsation, pressure value exceeding a preset range, bandage falling off or low battery.

[0153] It is understandable that the multifunctional segmented wearable electronic smart bandage described in this embodiment is further equipped with the following components: an alarm device, which is connected to the control module. The alarm device is specially designed to issue a warning signal in time when any abnormal condition is detected. The abnormal conditions referred to here may involve multiple aspects, such as abnormal patterns of blood vessel pulsation, monitored pressure values ​​exceeding a preset safety range, abnormal shedding of the smart bandage, or insufficient battery warnings to maintain the operation of the bandage. The addition of these alarm elements and functions significantly improves the real-time monitoring capabilities and user safety of the smart bandage system, ensuring that users can get the necessary protection and guidance during use.

[0154] In some embodiments of the present application, the inguinal bandage further comprises an electronic component for alarming when the bandage falls off, and the electronic component for alarming when the bandage falls off is used for real-time monitoring whether the bandage falls off.

[0155] In some embodiments of the present application, when the falling-off alarm electronic component detects that the groin bandage has fallen off, the falling-off alarm electronic component triggers an alarm and sends a falling-off alarm signal to an external device through a communication module.

[0156] Understandably, this design greatly enhances the safety and reliability of the multi-purpose segmented easy-to-wear electronic smart bandage, ensuring that users can receive timely feedback and assistance during use.

[0157] Specifically, the falling-off alarm electronic component is used to connect to the nurse station or doctor's office. When it is detected that the inguinal bandage has fallen off, a falling-off alarm signal can be immediately sent to the nurse station or doctor's office through the communication module. This instant communication function enables the medical team to quickly learn about the patient's condition, so as to take necessary medical measures to ensure the patient's safety and treatment effect. The falling-off alarm electronic component is exquisitely designed and can accurately monitor the status of the inguinal bandage. Once the bandage is detected to have fallen off, it will immediately activate the alarm system and emit a clear alarm sound to attract the patient's attention. At the same time, the component also has a seamless connection function with the communication module to ensure that the falling-off alarm signal can be quickly and accurately sent to the designated nurse station or doctor's office.

[0158] It can be seen that this design not only improves the safety of patients, but also enhances the work efficiency of the medical team. The medical team can quickly judge the patient's condition and take corresponding treatment measures through the received fall-off alarm signal. This timely feedback mechanism helps to reduce the risk of medical accidents and improve patient satisfaction with treatment.
