Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a tissue stretching and closing device for wound repair. Background Art

[0002] In the medical field, wound repair is a crucial treatment link, which is directly related to the patient's recovery process and quality of life. Especially for wounds after large-area burns, severe trauma or complex surgery, wound repair is more difficult and demanding. Traditional wound repair methods, such as direct suturing and skin grafting, can promote wound healing to a certain extent, but they have many limitations. For example, suturing may cause excessive tension on the wound and affect the quality of healing; skin grafting faces problems such as limited donors, complex surgery, long recovery time and possible rejection.

[0003] In recent years, with the continuous progress and innovation of medical technology, tissue stretch closure technology has gradually emerged as a new treatment method in the field of wound repair. This technology uses the physiological characteristics of the skin and the creep principle to gradually pull the wound edge, so that the wound gradually shrinks and eventually closes. Compared with traditional repair methods, tissue stretch closure technology has the advantages of simple operation, short recovery time, less scar formation and better repair effect.

[0004] However, despite the many advantages of this technology, existing tissue stretch closure devices still have some problems that need to be solved. For example, some devices have complex structures and are inconvenient to operate; some devices have unstable traction and are difficult to control accurately; and some devices may become loose or damaged after long-term use, affecting the treatment effect.

[0005] Therefore, the present invention proposes a tissue stretching and closing device for wound repair to solve the above problems. Summary of the invention

[0006] To solve the above problems, the present invention provides a tissue stretching and closing device for wound repair, which aims to achieve gradual stretching and closing of the wound edge through innovative mechanical design, while ensuring the simplicity of the operation process and the stability of the traction effect.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a tissue stretching and closing device for wound repair, comprising a fixing module for fixing the closing device on the user's body surface, a traction module being installed on the fixing module, the fixing module comprising a first shell and a second shell, a fixing assembly being arranged at the bottom of the first shell and the second shell, the traction module comprising a locking assembly, the locking assembly being embedded in the first shell, the locking assembly comprising a plurality of first beveled racks, one end of the first beveled racks being rotatably matched with the inside of the first shell, a plurality of second beveled racks being fixedly connected to the second shell, one end of the second beveled racks being away from the second shell being through the first shell, and the first beveled racks and the second beveled racks being snap-connected, an elastic member being fixedly connected to the side of the first beveled rack away from the second beveled rack, a limiting strip being slidably matched with the side of the elastic member being away from the first beveled rack, and the limiting strip being slidably matched with the inside of the first shell;

[0008] A circular hole is provided on the top of the first shell, in which a clamping block is rotatably engaged, and the clamping block is engaged and connected with the first bevel rack. A push rod is slidably engaged on one side of the first shell, and one end of the push rod is located inside the first shell and is fixedly connected to a limit bar, and the other end of the push rod is fixedly connected to a handle.

[0009] The technical principle of the above scheme is as follows: the fixing module is composed of a first shell and a second shell, both of which are equipped with fixing components at the bottom, which can ensure that the device will not move or fall off during use. The first shell and the second shell are specially designed to lock with each other to form a stable structure to provide support for the traction module.

[0010] The core of the traction module is the locking assembly, which is composed of a number of first beveled racks. One end of these first beveled racks is rotatably matched with the inside of the first shell, allowing them to rotate within a certain range. A number of second beveled racks are fixed to the second shell, and the ends of these second beveled racks away from the second shell pass through the first shell and are engaged and connected with the first beveled racks. When the first shell and the second shell move relative to each other, the engagement relationship between the first beveled rack and the second beveled rack will change, thereby generating traction. Elastic parts are installed on the side of the first beveled rack away from the second beveled rack. These elastic parts provide a reset force for the first beveled rack to ensure that they can return to their initial position when not affected by external forces. The side of the elastic part away from the first beveled rack is slidably matched with a limit strip, and these limit strips are slidably matched with the inside of the first shell. The function of the limit strip is to limit the movement range of the first beveled rack.

[0011] The above scheme has the following beneficial effects:

[0012] 1. In this solution, the locking function of the traction module is realized by the snap connection between the first bevel rack and the second bevel rack. Compared with the simple rope fixation in the prior art, the design of the present invention provides a more stable and reliable traction force transmission, ensuring the continuity and stability of the traction force during the wound repair process, which helps to improve the repair effect.

[0013] 2. This solution, by providing elastic parts and limit strips, enables the first bevel rack to have a certain buffering and adaptive ability when subjected to external force, thereby avoiding unnecessary pressure or damage to the user's body surface due to excessive tightening. Compared with the design of the prior art that lacks a buffer mechanism, it improves the safety and comfort of use.

[0014] 3. This solution, through the design of the push rod and the handle, allows the user to easily operate the locking and releasing of the traction module without complicated tools or skills. Compared with the existing equipment that is cumbersome to operate or requires professional assistance, it greatly simplifies the use process and improves the user's independent operation ability and convenience.

[0015] 4. In this solution, during the propulsion process, since the second bevel rack on the second shell is engaged with the first bevel rack in the first shell, it can be ensured that no excessive gap or looseness will be generated during the propulsion process, thereby ensuring the continuity and stability of traction. Compared with the gap or looseness problems that may occur in the prior art, this solution is more reliable.

[0016] 5. In this solution, the engagement and disengagement of the first bevel rack and the second bevel rack can be controlled at any time by rotating the clamping block, so that the traction force and distance can be flexibly adjusted according to actual conditions during the wound repair process. Compared with the problems of inconvenient adjustment or inability to flexibly adjust in the prior art, this solution is more flexible and adaptable.

[0017] Furthermore, the fixing assembly includes a suction cup, which is fixedly connected to the bottom of the first shell and the bottom of the second shell, and an adhesive layer is fixedly connected around the bottom of the first shell and the bottom of the second shell.

[0018] Beneficial effects: The fixing component includes a suction cup and an adhesion layer, and the suction cup is fixedly connected to the bottom of the first shell and the second shell. This design provides a dual fixing method. The suction cup can use the principle of negative pressure to fit tightly to the user's body surface, ensuring that the device is not easy to fall off or shift during use, thereby improving the stability and safety of use. At the same time, the adhesion layer can further enhance the fixing effect as an auxiliary fixing means, especially when the suction cup may not be able to fully function due to an uneven or wet body surface. The adhesion layer can play an important supplementary role. Compared with the problems of unstable fixation or easy falling off that may exist in the prior art, the fixing component of this solution is more stable and reliable.

[0019] Furthermore, a tension sensor is installed on the second bevel rack, the tension sensor signal is connected to the controller, the controller signal is connected to the early warning module, and the controller sends a reminder instruction to the early warning module according to the tension data monitored in real time by the tension sensor.

[0020] Beneficial effects: A tension sensor is installed on the second bevel rack, and a signal connection is achieved with the controller and the early warning module. This design enables real-time monitoring of the tension data generated by traction during the wound repair process. Based on the data fed back by the tension sensor, the controller can accurately determine whether the current traction force is appropriate and whether the expected repair effect has been achieved. Once the tension data exceeds the preset safety range, the controller will immediately send a reminder instruction to the early warning module, thereby issuing an early warning signal in a timely manner. Compared with the problems of being unable to monitor tension in real time or untimely early warning that may exist in the prior art, this real-time monitoring and early warning mechanism can significantly improve the safety and controllability of wound repair and effectively avoid excessive or insufficient traction.

[0021] Furthermore, a connecting assembly is installed between the first shell and the second shell. The connecting assembly includes a bellows. Both ends of the bellows are fixedly connected to the side walls of the first shell and the second shell respectively. A plurality of one-way valves are installed on the bellows.

[0022] Beneficial effects: A connecting assembly is installed between the first shell and the second shell, and the assembly includes a bellows and a one-way valve. In the process of pushing the first shell and the second shell, the bellows will be gradually squeezed, and the air inside it will be effectively squeezed out through the one-way valve, forming a slight airflow blowing on the wound. This design not only helps to keep the wound dry and reduce the risk of infection caused by a humid environment, but also promotes blood circulation in the wound, providing more oxygen and nutrients to the wound, thereby accelerating the healing process. Compared with the problems of insufficient wound environment control or slow healing speed that may exist in the prior art, this solution significantly improves the effect and speed of wound repair through the innovative design of the connecting assembly.

[0023] Furthermore, temperature sensors are installed on both the first shell and the second shell. The temperature sensors are connected to the controller signal. The controller sends a reminder instruction to the early warning module according to the temperature data monitored in real time by the temperature sensor.

[0024] Beneficial effects: Temperature sensors are installed on both the first shell and the second shell, and signal connection is achieved with the controller. This design enables real-time monitoring of the temperature data of the shell and its surrounding environment during the wound repair process. Based on the data fed back by the temperature sensor, the controller can accurately determine whether the current temperature is suitable for wound repair and whether it may cause overheating or overcooling. Once the temperature data exceeds the preset safety range, the controller will immediately send a reminder instruction to the early warning module, thereby issuing an early warning signal in a timely manner. Compared with the problems of being unable to monitor temperature in real time or untimely early warning that may exist in the prior art, this real-time monitoring and early warning mechanism can significantly improve the safety and comfort of wound repair and effectively avoid potential risks caused by inappropriate temperature.

[0025] Furthermore, the early warning module includes an indicator light and a buzzer. The indicator light is used to flash and emit light of different colors, and the buzzer is used to emit different alarm sounds. Both the indicator light and the buzzer are connected to the controller signal. When the controller determines that any one of the real-time tension data and temperature exceeds a preset threshold, the early warning module emits an audible and visual alarm signal.

[0026] Beneficial effects: The early warning module includes an indicator light and a buzzer, both of which are connected to the controller signal and can emit an audible and visual alarm signal when the real-time tension data or temperature exceeds the preset threshold. This design makes the early warning information more intuitive and eye-catching, and can quickly attract the user's attention. The indicator light can clearly indicate different early warning reminders by flashing and emitting light of different colors, such as red for emergency warnings, yellow for attention warnings, etc. At the same time, the buzzer emits different alarm sounds, which can further enhance the early warning effect and ensure that users can receive early warning information in time even in a noisy environment. Compared with the problems that may exist in the prior art, such as insufficient early warning means, and the early warning information is not intuitive enough or easily overlooked, the early warning module design of this solution is more complete and effective, and can significantly improve the safety and reliability of the wound repair process.

[0027] Furthermore, it also includes a remote monitoring module, which is connected to the controller signal. The remote monitoring module is used to receive and display the tension data and temperature data transmitted by the controller in real time. The remote monitoring module is connected to the smart terminal signal. Medical staff and users can obtain early warning information in real time through the smart terminal.

[0028] Beneficial effects: By introducing the connection between the remote monitoring module and the intelligent terminal, remote real-time monitoring of the wound repair process is realized. The remote monitoring module can receive and display the tension data and temperature data transmitted by the controller in real time, so that medical staff and users can always understand the key parameters in the wound repair process even if they are not on site. This design not only improves the real-time and accuracy of monitoring, but also provides medical staff with a more convenient and efficient remote management method. Compared with the problems that monitoring data cannot be obtained in real time or remote management may be inconvenient in the prior art, this solution significantly improves the transparency and controllability of the wound repair process.

[0029] Furthermore, it includes a personalized setting module, which is connected to the controller signal, and is used to adjust the tension threshold, temperature threshold and early warning module through the controller.

[0030] Beneficial effects: By introducing a personalized setting module, flexible adjustment of the tension threshold, temperature threshold and early warning module is achieved. This design fully takes into account the personalized needs of different users, different wound repair plans and different environmental conditions. Medical staff and users can accurately set the tension threshold and temperature threshold through the personalized setting module according to actual conditions to ensure that the traction force and temperature environment during the wound repair process are always in the best state. At the same time, users can also personalize the alarm mode, alarm volume and other parameters of the early warning module according to their preferences and needs to improve the reception effect and comfort of early warning information. Compared with the problems of inflexible settings and inability to meet personalized needs in the prior art, this solution significantly improves the personalization level and user experience of the wound repair process.

[0031] Furthermore, all components of the device are made of materials with biocompatibility and antibacterial properties.

[0032] Beneficial effects: All device parts that come into direct or indirect contact with the wound, including but not limited to the first shell, the second shell, the connection assembly, the temperature sensor, etc., are made of materials with biocompatibility and antibacterial properties. This design ensures that the device will not cause any biological rejection or allergic reaction to the wound during use, thereby improving the safety and reliability of wound repair. At the same time, materials with antibacterial properties can effectively inhibit the growth and reproduction of bacteria, reduce the risk of infection, and provide a cleaner and safer repair environment for the wound.

[0033] Furthermore, it also includes a battery module and a wireless charging module, both of which are installed inside the second shell. The battery module provides power support for the tension sensor and the temperature sensor. The wireless charging module is used to wirelessly charge the battery module. The wireless charging module is signal-connected to the battery module. The battery module also has a power monitoring function. When the power is lower than a preset threshold, a low power reminder is sent to the early warning module through the controller.

[0034] Beneficial effects: By integrating the battery module and the wireless charging module, the wound repair device achieves self-sufficient power supply and convenient charging. The battery module not only provides stable power support for key components such as tension sensors and temperature sensors, ensuring the accuracy and real-time nature of monitoring data, but also enables the device to continue working without relying on external power sources, improving the flexibility and convenience of use. The design of the wireless charging module avoids the tediousness and inconvenience that may be caused by traditional wired charging methods. Users only need to place the device on the charging stand to achieve automatic charging, greatly improving the efficiency and convenience of charging.

[0035] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The following is further described in detail through specific implementation methods:

[0046] Embodiment 1:

[0047] As attached Figures 1 to 5 As shown: A tissue stretching closure device for wound repair, including a fixing module for fixing the closure device on the user's body surface, a traction module is installed on the fixing module, the fixing module includes a first shell 1 and a second shell 2, the bottom of the first shell 1 and the second shell 2 are both provided with a fixing assembly, the fixing assembly includes a suction cup 10, the suction cup 10 is fixedly connected to the bottom of the first shell 1 and the second shell 2, and the bottom of the first shell 1 and the second shell 2 are all fixedly connected with an adhesion layer 11. The fixing module combines physical adsorption (suction cup 10) and biological adhesion (adhesion layer 11) to ensure that the device is stably fixed to the user's body surface, avoid displacement during traction, and thus ensure the effectiveness and safety of treatment. All components of the device are made of materials with biocompatibility and antibacterial properties.

[0048] The traction module includes a locking assembly, which is embedded in the first shell 1. The locking assembly includes a plurality of first bevel racks 3, one end of each of which is rotatably matched with the inside of the first shell 1. A plurality of second bevel racks 4 are fixedly connected to the second shell 2. One end of each of the second bevel racks 4 away from the second shell 2 penetrates the first shell 1 and slides with the first shell 1. The first bevel racks 3 and the second bevel racks 4 are engaged and connected (combined with the first bevel racks 3 and the second bevel racks 4). Figure 3 As shown), the first bevel rack 3 is fixedly connected with an elastic member 5 on the side away from the second bevel rack 4. In this embodiment, the elastic member 5 is an elastic metal sheet. The elastic member 5 is slidably engaged with a limit strip 6 on the side away from the first bevel rack 3, and the limit strip 6 is slidably engaged with the inside of the first shell 1; a round hole is opened on the top of the first shell 1, and a clamping block 7 is rotatably engaged in the round hole. The clamping block 7 is engaged and connected with the first bevel rack 3, and a push rod 8 is slidably engaged with one side of the first shell 1. The push rod 8 is located inside the first shell 1, and one end is fixedly connected to the limit strip 6, and the other end of the push rod 8 is fixedly connected to a handle 9.

[0049] A tension sensor is installed on the second bevel rack 4, and the tension sensor signal is connected to the controller, and the controller signal is connected to the early warning module. The controller sends a reminder instruction to the early warning module according to the tension data monitored in real time by the tension sensor. It is helpful to timely discover and warn of potential over-traction risks, prevent tissue damage caused by excessive tension, and improve the safety and controllability of treatment. The early warning module includes an indicator light and a buzzer. The indicator light is used to flash and emit light of different colors to indicate different early warning reminders, and the buzzer is used to emit different alarm sounds. The indicator light and the buzzer are both connected to the controller signal. When the controller determines that any one of the real-time tension data or temperature exceeds the preset threshold, the early warning module emits an audible and visual alarm signal to remind the user to take timely measures. For example, green may mean that everything is normal, yellow means that it is about to exceed the threshold slightly and needs attention, and red means that it is seriously exceeding the threshold and needs to be adjusted immediately. The buzzer distinguishes different alarm levels through different tones or frequencies so that medical staff can quickly identify and respond.

[0050] It also includes a battery module and a wireless charging module, both of which are installed inside the second shell 2. The battery module provides power support for the tension sensor and the temperature sensor, and the wireless charging module is used to wirelessly charge the battery module. The wireless charging module is connected to the battery module signal. The battery module also has a power monitoring function. When the power is lower than the preset threshold, a low power reminder is sent to the early warning module through the controller. The overall portability and endurance of the device are improved, and the inconvenience caused by battery replacement is reduced. At the same time, the application of wireless charging technology also improves the safety and hygiene of use.

[0051] The specific implementation process is as follows: Before using the tissue stretch closure device, the patient's wound surface needs to be evaluated first, including the size, location, depth of the wound surface and the health of the surrounding tissues. At the same time, understand the patient's allergy history and ensure that the selected fixing component (especially the adhesion layer 11) material has no allergic reaction to the patient. Before installing the fixing module, the area around the patient's body surface wound surface needs to be thoroughly cleaned and disinfected to reduce the risk of infection. Use sterile saline or appropriate disinfectant for cleaning, and ensure that it is dry before proceeding to the next step.

[0052] According to the actual situation of the user and the need for wound repair, the first shell 1 and the second shell 2 are fixed on both sides of the wound on the user's body surface through a fixing component to ensure that the distance between the two is moderate, so as to facilitate the subsequent traction operation, and at the same time, it will not cause discomfort to the user due to the distance being too close. That is, by pressing the first shell 1 and the second shell 2, the suction cup 10 at the bottom thereof is tightly fitted on the user's body surface. The suction cup 10 utilizes the principle of physical adsorption to stably fix the fixing module on the user's body surface through the action of negative pressure. At the same time, the adhesion layer 11 around the bottom of the first shell 1 and the second shell 2 will also adhere to the user's body surface at the outer edge of the suction cup 10, further enhancing the fixing effect. The adhesion layer 11 is made of bioadhesive material, which has good biocompatibility and adhesion, and can ensure that the fixing module will not be displaced during the traction process, and will not cause irritation or damage to the skin.

[0053] According to the wound repair plan, the fixed first shell 1 and second shell 2 are pushed toward the middle. Since the second bevel rack 4 on the second shell 2 is engaged with the first bevel rack 3 in the first shell 1, the second bevel rack 4 and the first bevel rack 3 are locked with each other during the advancement process, thereby achieving a locking effect and properly traction the wound. During the advancement process, close attention should be paid to the user's reaction and the condition of the wound to ensure that the traction force is moderate, so that neither excessive traction nor insufficient traction affects the repair effect.

[0054] During the traction process, the tension sensor will continuously monitor the tension data and transmit it to the controller. The controller determines whether the current tension is within a safe range based on the preset threshold. If the tension data exceeds the preset threshold, the controller will immediately send a reminder instruction to the early warning module. The early warning module includes an indicator light and a buzzer, which will simultaneously send out an audible and visual alarm signal to remind the user to take timely measures. The user can judge the current tension state according to the flashing color of the indicator light and the alarm sound of the buzzer, and take corresponding measures to adjust it. For example, if the tension is too large, the locking force between the first shell 1 and the second shell 2 can be appropriately relaxed; if the tension is too small, the locking force can be increased to enhance the traction effect.

[0055] When the wound surface repair reaches the expected effect or needs to be stopped, the user pushes the push rod 8 through the handle 9, and the push rod 8 pushes the limit bar 6, and the limit bar 6 slides and fits inside the first shell 1. Then turn the block 7 (such as Figure 3As shown, both rotate toward the center, that is, the upper block 7 rotates counterclockwise, and the lower block 7 rotates clockwise), the block 7 squeezes the first bevel rack 3 toward the side of the limit bar 6, so that the first bevel rack 3 and the second bevel rack 4 are out of engagement, and the second bevel rack 4 can retreat, thereby increasing the distance between the first shell 1 and the second shell 2. Release can be gradually released to avoid rapid release causing further damage to the wound surface. During the process, the block 7 can be rotated at any time (such as Figure 3 As shown, both rotate outward, that is, the upper block 7 rotates clockwise, and the lower block 7 rotates counterclockwise), so that the first bevel rack 3 can be reset under the action of the elastic member 5 and continue to maintain the engagement connection with the second bevel rack 4.

[0056] Embodiment 2:

[0057] As attached Figure 4 As shown, the difference from Example 1 is that a connecting assembly is installed between the first shell 1 and the second shell 2, and the connecting assembly includes a bellows 12, both ends of the bellows 12 are fixedly connected to the side walls of the first shell 1 and the second shell 2 respectively, and a plurality of one-way valves are installed on the bellows 12.

[0058] The specific implementation process is as follows: According to the wound repair plan, in the process of slowly pushing the first shell 1 and the second shell 2 toward the middle, the bellows 12 connected between the first shell 1 and the second shell 2 will be gradually squeezed. When the bellows 12 is squeezed, the air inside it is pushed toward the one-way valve. Since the design of the one-way valve only allows air to flow in one direction (for example, from the inside of the bellows 12 to the outside), the air will be effectively squeezed out of the bellows 12 without flowing back. After the squeezed air passes through the one-way valve, a slight airflow will be formed, blowing directly onto the wound. This blowing effect helps to keep the wound dry and reduce the risk of infection. It also helps to promote blood circulation in the wound and accelerate the healing process.

[0059] Embodiment 3:

[0060] The difference from Example 2 is that temperature sensors are installed on both the first shell 1 and the second shell 2, and the temperature sensors are connected to the controller signal. The controller sends a reminder instruction to the early warning module according to the temperature data monitored in real time by the temperature sensor.

[0061] The specific implementation process is as follows: During the traction process, the temperature sensors installed on the first shell 1 and the second shell 2 begin to monitor the temperature of the wound surface and its surrounding tissues in real time. The temperature data is transmitted to the controller in real time, and the controller analyzes it according to the preset temperature threshold. If the temperature monitored by the temperature sensor exceeds the preset safety range (such as too high or too low), the controller will immediately send a reminder instruction to the early warning module. The early warning module (indicator light and buzzer) will simultaneously send out sound and light alarm signals to prompt the operator to pay attention.

[0062] The operator needs to make a comprehensive judgment on the current situation based on the prompts of the early warning module. If the temperature is abnormal, it may be a sign of wound infection, blood circulation disorder and other problems. The traction should be stopped immediately, the wound should be checked and corresponding measures should be taken. At the same time, the patient is also reminded to maintain a suitable temperature around the wound to avoid an environment that is not suitable for wound recovery.

[0063] Embodiment 4:

[0064] The difference from Example 3 is that it also includes a remote monitoring module, which is connected to the controller signal. The remote monitoring module is used to receive and display the tension data and temperature data transmitted by the controller in real time. The remote monitoring module can be connected to the smart terminal (such as a mobile phone, tablet or computer) by signal, and medical staff and users can obtain warning information in time through the smart terminal.

[0065] The specific implementation process is as follows: Connect the remote monitoring module to the controller via wired or wireless means to ensure a stable and reliable connection for subsequent data transmission and communication. Configure the communication parameters of the remote monitoring module, such as IP address, port number, etc., to establish a communication connection with the smart terminal. Ensure that the smart terminal (such as a mobile phone, tablet or computer) can access the network where the remote monitoring module is located.

[0066] Medical staff and users need to install the designated monitoring software on the smart terminal. The software should support real-time data reception, display and warning functions. Configure the address and port number of the remote monitoring module in the monitoring software to receive data. Set the warning threshold so that a warning is issued when the data exceeds the normal range. The controller transmits the real-time monitored tension data and temperature data to the smart terminal through the remote monitoring module. The transmission process should ensure the accuracy and real-time nature of the data.

[0067] The monitoring software displays the tension data and temperature data in real time on the smart terminal. The data can be displayed intuitively in the form of charts, curves, etc., which is convenient for medical staff and users to observe and analyze. The monitoring software determines whether the data is abnormal based on the preset warning threshold. If the data exceeds the normal range, the warning mechanism is triggered. The monitoring software sends warning information to medical staff and users through the smart terminal. The warning information can include detailed information such as the type, degree, and time of the data abnormality. The warning method can be sound, vibration, pop-up window, etc. to ensure that medical staff and users can notice the warning information in time.

[0068] Embodiment 5:

[0069] The difference from Example 4 is that it also includes a personalized setting module, which is connected to the controller signal and is used to adjust the tension threshold, temperature threshold and early warning module through the controller.

[0070] The specific implementation process is as follows: Connect the personalized setting module to the controller by wire or wireless means to ensure that the connection is stable and reliable for subsequent data transmission and setting adjustment. Configure the interface and communication protocol of the personalized setting module in the controller to ensure that the controller can correctly identify and process the signals from the personalized setting module.

[0071] Through the personalized setting module, medical staff and users can set the tension threshold according to their needs. When the tension data monitored by the tension sensor reaches or exceeds the set threshold, the early warning module will issue an early warning signal. Similarly, medical staff and users can set the temperature threshold through the personalized setting module. When the temperature data monitored by the temperature sensor reaches or exceeds the set threshold, the early warning module will also issue an early warning signal. The personalized setting module also allows medical staff and users to set the early warning method of the early warning module, such as sound, vibration, pop-up window, etc. Users can choose the appropriate early warning method according to their preferences and needs.

[0072] Specific examples are as follows: Medical staff and users first need to enter the personalized settings interface through a smart terminal (such as a mobile phone, tablet or computer). In the personalized settings interface, users can select the settings that need to be adjusted, such as tension threshold, temperature threshold or warning module. According to actual needs, users can adjust the corresponding parameter values ​​through sliders, input boxes, etc. After the adjustment is completed, the user needs to click the Save button to save the setting parameters to the controller. After the controller receives the new setting parameters, it will automatically apply these parameters so that it can work according to the new threshold and warning method in the subsequent monitoring process.

[0073] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
