Description

TECHNICAL FIELD

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

[0002] In the medical field, wound repair is a crucial treatment step that directly affects the patient's recovery process and quality of life. Especially for large-area burns, severe trauma or postoperative wounds, wound repair is more difficult and demanding. Traditional wound repair methods, such as direct suture, skin graft surgery, etc., can promote wound healing to some extent, but have many limitations. For example, suture may cause excessive tension on the wound, affecting healing quality; skin graft surgery faces limited donor sites, complex surgery, long recovery time, and possible rejection reactions.

[0003] In recent years, with the continuous progress and innovation of medical technology, tissue stretching and closing technology has gradually emerged as a new treatment method in the field of wound repair. This technology takes advantage of the physiological properties and creep principle of the skin, gradually stretching the wound edges to gradually reduce the wound and ultimately achieve closure. Compared with traditional repair methods, tissue stretching and closing technology has the advantages of simple operation, short recovery time, less scarring, and good repair results.

[0004] However, despite the many advantages of this technology, existing tissue stretching and closing devices still have some problems that need to be addressed. For example, some devices have complex structures and are difficult to operate; the traction force of some devices is unstable and difficult to control accurately; and some devices may loosen or break after long-term use, affecting treatment effectiveness.

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

[0006] To solve the above problems, the present application provides a tissue stretching and closing device for wound repair, aiming to achieve gradual stretching and closure of wound edges 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 object, the technical scheme of the present application is as follows: A tissue stretching and closing device for wound repair, comprising a fixing module for fixing the device on the surface of a user, a traction module mounted on the fixing module, the fixing module comprising a first shell and a second shell, each of the first shell and the second shell being provided with a fixing assembly at the bottom, the traction module comprising a locking assembly embedded in the first shell, the locking assembly comprising a plurality of first bevel gears, each of the first bevel gears being rotatably connected to the inside of the first shell, the second shell being fixedly connected with a plurality of second bevel gears, each of the second bevel gears being penetrated through the first shell from the side away from the second shell and being connected with the first bevel gears, the side of the first bevel gears away from the second bevel gears being fixedly connected with elastic members, the side of the elastic members away from the first bevel gears being slidably connected with limiting rods, the limiting rods being slidably connected with the inside of the first shell.

[0008] A circular hole is formed at the top of the first shell, a clamping block being rotatably connected in the circular hole, the clamping block being connected with the first bevel gears, a push rod being slidably connected with the side of the first shell, the end of the push rod inside the first shell being fixedly connected with the limiting rod, the other end of the push rod being fixedly connected with a handle.

[0009] The technical principle of the above-mentioned scheme is as follows: The fixing module is composed of a first shell and a second shell, each of which is provided with a fixing assembly at the bottom, which can ensure that the device will not move or fall off during use. The first shell and the second shell can be locked with each other through special design, forming 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 plurality of first bevel gears. One end of each of the first bevel gears is rotatably connected to the inside of the first shell, allowing them to rotate within a certain range. The second shell is fixedly connected with a plurality of second bevel gears, the ends of the second bevel gears away from the second shell being penetrated through the first shell and being connected with the first bevel gears. When the first shell and the second shell move relative to each other, the connection between the first bevel gears and the second bevel gears will change, thereby generating a traction force. The side of the first bevel gears away from the second bevel gears is provided with elastic members, which provide a restoring force for the first bevel gears to ensure that they can return to the initial position when not subjected to external force. The side of the elastic members away from the first bevel gears is slidably connected with limiting rods, which are slidably connected with the inside of the first shell. The limiting rods limit the movement range of the first bevel gears.

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

[0012] 1. In this scheme, the connection between the first bevel gears and the second bevel gears realizes the locking function of the traction module, which provides more stable and reliable transmission of traction force compared with the simple rope fixation in the prior art, ensuring the continuity and stability of the traction force during wound repair and helping to improve the repair effect.

[0013] 2、The first inclined rack has certain buffering and self-adaptive ability when subjected to external force, avoiding unnecessary pressure or damage to the user's body caused by excessive locking, and improving the safety and comfort of use compared with the design lacking a buffering mechanism in the prior art.

[0014] 3、The user can conveniently operate the locking and release of the traction module through the design of the push rod and handle, without the need for complex tools or skills, greatly simplifying the use process and improving the user's self-operation ability and convenience compared with the instruments that are cumbersome to operate or require professional assistance in the prior art.

[0015] 4、During the advancement, the second inclined rack on the second shell is connected with the first inclined rack in the first shell, so that excessive gap or looseness is avoided during the advancement, thereby ensuring the continuity and stability of traction, and the present solution is more reliable compared with the gap or looseness problem that may occur in the prior art.

[0016] 5、The first inclined rack and the second inclined rack can be connected and disconnected at any time by rotating the clamping block, so that the traction force and distance can be flexibly adjusted according to the actual situation during wound repair, and the present solution is more flexible and adaptable compared with the adjustment inconvenience or inability to flexibly adjust that may exist in the prior art.

[0017] Further, the fixing assembly includes suction cups, and the suction cups are fixedly connected to the bottom of the first shell and the second shell.

[0018] Beneficial effects: The fixing assembly includes suction cups and an adhesive layer, and the suction cups are fixedly connected to the bottom of the first shell and the second shell. This design provides a double fixing method. The suction cups can be tightly attached to the user's body surface using the negative pressure principle, ensuring that the instrument is not easily detached or displaced during use, improving the stability and safety of use. At the same time, the adhesive layer as an auxiliary fixing means can further enhance the fixing effect, especially in the case that the suction cups may not fully function due to uneven or wet body surface, the adhesive layer can play an important complementary role. Compared with the instability or easy detachment problem that may exist in the prior art, the fixing assembly of the present solution is more stable and reliable.

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

[0020] Beneficial effects: The tension sensor is installed on the second oblique rack and is signal connected with the controller and the early warning module. This design enables real-time monitoring of the tension data generated during wound repair. The controller can accurately determine whether the current traction force is appropriate and whether the expected repair effect is achieved according to the data fed back by the tension sensor. 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 time. Compared with the existing technology that may have problems such as inability to monitor tension in real time or untimely warning, the real-time monitoring and early warning mechanism can significantly improve the safety and controllability of wound repair, effectively avoiding excessive traction or insufficient traction.

[0021] Further, a connecting assembly is installed between the first shell and the second shell, the connecting assembly comprising a bellows, the bellows being fixedly connected to the side walls of the first shell and the second shell at two ends, and a plurality of one-way valves being installed on the bellows.

[0022] Beneficial effects: A connecting assembly is installed between the first shell and the second shell, the assembly comprising a bellows and one-way valves. During the process of pushing the first shell and the second shell, the bellows will be gradually squeezed, and the air inside will be effectively squeezed out through the one-way valves, forming a slight air flow 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 existing technology that may have problems such as insufficient control of the wound environment or slow healing speed, the innovative connecting assembly design significantly improves the effect and speed of wound repair.

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

[0024] Beneficial effects: Temperature sensors are installed on the first shell and the second shell and are signal connected with the controller. This design enables real-time monitoring of the temperature data of the shells and their surrounding environment during wound repair. The controller can accurately determine whether the current temperature is suitable for wound repair and whether it may lead to overheating or overcooling according to the data fed back by the temperature sensors. 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 time. Compared with the existing technology that may have problems such as inability to monitor temperature in real time or untimely warning, the real-time monitoring and early warning mechanism can significantly improve the safety and comfort of wound repair, effectively avoiding potential risks caused by unsuitable temperature.

[0025] Further, the early warning module includes an indicator light and a buzzer, the indicator light is used for flashing and emitting light of different colors, and the buzzer is used for emitting different alarm sounds, and the indicator light and the buzzer are both connected with the controller signal, when the controller judges that any one of the real-time tension data and the temperature exceeds the preset threshold value, 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, which are both connected with the controller signal, and can emit an audible and visual alarm signal when the real-time tension data or the temperature exceeds the preset threshold value. 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 warning and yellow for attention warning. At the same time, the buzzer emits different alarm sounds, which can further enhance the early warning effect and ensure that the user can receive the early warning information in time even in a noisy environment. Compared with the possible problems of insufficient early warning means, non-intuitive early warning information or easy to be ignored in the prior art, the early warning module design of the present scheme is more perfect and effective, which can significantly improve the safety and reliability in the wound repair process.

[0027] Further, a remote monitoring module is further included, the remote monitoring module is connected with the controller signal, the remote monitoring module is used for receiving and displaying the tension data and the temperature data transmitted by the controller in real time, the remote monitoring module is connected with an intelligent terminal, and medical staff and users can obtain early warning information in real time through the intelligent terminal.

[0028] Beneficial effects: by introducing the connection of 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 the temperature data transmitted by the controller in real time, so that the medical staff and the user can know the key parameters in the wound repair process at any time even if they are not on site. This design not only improves the real-time and accuracy of monitoring, but also provides more convenient and efficient remote management means for medical staff. Compared with the possible problems of unable to obtain monitoring data in real time or inconvenient remote management in the prior art, the present scheme significantly improves the transparency and controllability of the wound repair process.

[0029] Further, a personalized setting module is included, the personalized setting module is connected with the controller signal, and the personalized setting module is used for adjusting the tension threshold value, the temperature threshold value and the early warning module through the controller.

[0030] Beneficial effects: By introducing the individualized setting module, flexible adjustment of the tension threshold, temperature threshold and warning module is realized. This design fully considers the individualized 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 individualized setting module according to the actual situation, to ensure that the traction degree and temperature environment in the wound repair process are always in the best state. At the same time, users can also individualize the alarm mode, alarm volume and other parameters of the warning module according to their own preferences and needs, to improve the reception effect and comfort of the warning information. Compared with the existing technology, which may have the problem of inflexible setting and inability to meet individualized needs, the present scheme significantly improves the individualization degree and user experience of the wound repair process.

[0031] Further, all parts 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 housing, the second housing, the connecting assembly, the temperature sensor, etc., are made of materials with biocompatibility and antibacterial properties. This design ensures that the device does not cause any biological rejection or allergic reactions during use, thereby improving the safety and reliability of wound repair. At the same time, the antibacterial properties of the material can effectively inhibit the growth and reproduction of bacteria, reducing the risk of infection and providing a cleaner and safer repair environment for the wound.

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

[0034] Beneficial effects: By integrating the battery module and the wireless charging module, self-sufficient power supply and convenient charging method for the wound repair device are realized. The battery module not only provides stable power support for key components such as the tension sensor and the temperature sensor, ensuring the accuracy and real-time of monitoring data, but also enables the device to work continuously without relying on external power supply, improving the flexibility and convenience of use. The design of the wireless charging module avoids the inconvenience and inconvenience that may be brought by traditional wired charging method. Users only need to place the device on the charging base to realize automatic charging, greatly improving the efficiency and convenience of charging.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] The following detailed description illustrates the specific implementation method:

[0046] Example 1:

[0047] As attached Figures 1 to 5 The image shows a tissue traction closure device for wound repair, comprising a fixation module for securing the closure device to the user's body surface. A traction module is mounted on the fixation module. The fixation module includes a first housing 1 and a second housing 2. Fixation components are provided at the bottom of both the first housing 1 and the second housing 2. Each fixation component includes a suction cup 10, which is fixedly connected to the bottom of both the first housing 1 and the second housing 2. Adhesive layers 11 are fixedly connected to the four sides of the bottom of both the first housing 1 and the second housing 2. The fixation module combines physical adsorption (suction cups 10) and bioadhesion (adhesive layers 11) to ensure the device is stably fixed to the user's body surface, preventing displacement during traction and thus ensuring the effectiveness and safety of the treatment. All components of the device are made of biocompatible and antibacterial materials.

[0048] The traction module includes a locking assembly embedded inside the first housing 1. The locking assembly includes several first helical racks 3, one end of which is rotatably engaged with the interior of the first housing 1. Several second helical racks 4 are fixedly connected to the second housing 2, the ends of which, away from the second housing 2, penetrate the first housing 1 and are slidably engaged with it. The first helical racks 3 and second helical racks 4 are also engaged (connected) to each other. Figure 3 As shown), an elastic element 5 is fixedly connected to the side of the first helical rack 3 away from the second helical rack 4. In this embodiment, the elastic element 5 is an elastic metal sheet. The side of the elastic element 5 away from the first helical rack 3 is slidably fitted with a limiting strip 6. The limiting strip 6 is slidably fitted with the inside of the first housing 1. A round hole is opened at the top of the first housing 1. A locking block 7 is rotatably fitted in the round hole. The locking block 7 is engaged with the first helical rack 3. A push rod 8 is slidably fitted on one side of the first housing 1. One end of the push rod 8 is fixedly connected to the limiting strip 6 inside the first housing 1. The other end of the push rod 8 is fixedly connected to a handle 9.

[0049] The second inclined rack 4 is provided with a tension sensor, the tension sensor is signal connected with a controller, the controller is signal connected with a warning module, and the controller sends a reminding instruction to the warning module according to the tension data monitored by the tension sensor in real time. It is helpful to discover and warn potential over-drawing risks in time, prevent tissue damage caused by excessive tension, and improve the safety and controllability of treatment. The warning module includes an indicator light and a buzzer, the indicator light is used to flash and emit different colors of light to represent different warning reminders, and the buzzer is used to emit different alarm sounds. The indicator light and the buzzer are signal connected with the controller, when the controller judges that any one of the real-time tension data or the temperature exceeds the preset threshold, the warning module sends an audible and light alarm signal to remind the user to take timely measures. For example, green may represent normal, yellow represents that the threshold is about to be exceeded and needs attention, and red represents that the threshold is seriously exceeded 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] The battery module and the wireless charging module are also included, and the battery module and the wireless charging module are both 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 for wireless charging of the battery module. The wireless charging module is signal connected with the battery module, and the battery module also has a power monitoring function. When the power is lower than the preset threshold, the controller sends a low power reminder to the warning module. The overall portability and endurance of the device are improved, the inconvenience caused by battery replacement is reduced, and 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 stretching closure device, the wound of the patient needs to be evaluated first, including the size, position, depth of the wound and the health condition of the surrounding tissue. At the same time, the patient's allergy history is understood to ensure that the selected fixed component (especially the adhesion layer 11) material has no allergic reaction to the patient. Before installing the fixed module, the area around the patient's body surface wound 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 of the user's body surface through the fixing assembly, ensuring that the distance between them is moderate to facilitate subsequent traction operation, and also not too close to bring discomfort to the user. That is, by pressing the first shell 1 and the second shell 2, the suction cups 10 at the bottom thereof are tightly attached to the user's body surface. The suction cups 10 use the physical adsorption principle to stably fix the fixing module on the user's body surface through negative pressure. At the same time, the adhesive layer 11 around the bottom of the first shell 1 and the second shell 2 also adheres to the user's body surface outside the edge of the suction cups 10, further enhancing the fixing effect. The adhesive layer 11 uses biological adhesion material, which has good biocompatibility and adhesion, and can ensure that the fixing module does not displace during traction, and also does 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 towards the middle. Since the second inclined rack 4 on the second shell 2 is connected with the first inclined rack 3 in the first shell 1, during the pushing process, the second inclined rack 4 and the first inclined rack 3 are mutually locked, thereby achieving a locking effect, and the wound is properly pulled. During the pushing process, the user's reaction and the condition of the wound should be closely observed to ensure that the pulling force is moderate, neither causing excessive pulling nor being insufficient to affect the repair effect.

[0054] During the pulling process, the tension sensor continuously monitors the tension data and transmits it to the controller. The controller determines whether the current tension is within the safe range according to the preset threshold value. If the tension data exceeds the preset threshold value, the controller will immediately send a reminder instruction to the warning module. The warning module includes an indicator light and a buzzer, which will simultaneously issue an audible and visual alarm signal to remind the user to take timely measures. The user can determine the current tension state according to the flashing color of the indicator light and the alarm sound of the buzzer, and take appropriate measures to adjust. 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 pulling effect.

[0055] When the wound repair reaches the desired effect or needs to stop using, the user pushes the push rod 8 through the handle 9, the push rod 8 pushes the limiting strip 6, and the limiting strip 6 slides in the first shell 1. Then rotate the clamping block 7 (such as Figure 3As shown, both rotate towards the center direction, i.e. the upper clamping block 7 rotates counterclockwise, and the lower clamping block 7 rotates clockwise), the clamping block 7 will press the first bevel gear 3 towards the side of the limiting strip 6, so that the first bevel gear 3 and the second bevel gear 4 are disengaged, and the second bevel gear 4 can retreat, thereby pulling apart the distance between the first shell 1 and the second shell 2. When released, it can be gradually released to avoid re-injury to the wound surface caused by rapid release. At any time during the process, the clamping block 7 can be rotated (for example Figure 3 As shown, both rotate towards the center direction, i.e. the upper clamping block 7 rotates counterclockwise, and the lower clamping block 7 rotates clockwise), the clamping block 7 will press the first bevel gear 3 towards the side of the limiting strip 6, so that the first bevel gear 3 and the second bevel gear 4 are disengaged, and the second bevel gear 4 can retreat, thereby pulling apart the distance between the first shell 1 and the second shell 2. When released, it can be gradually released to avoid re-injury to the wound surface caused by rapid release. At any time during the process, the clamping block 7 can be rotated (for example

[0056] Example 2:

[0057] As shown in the accompanying Figure 4 The difference from example 1 is that a connecting assembly is installed between the first shell 1 and the second shell 2, the connecting assembly includes a bellows 12, the two ends of the bellows 12 are fixedly connected with 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, a process of slowly pushing the first shell 1 and the second shell 2 towards the middle is started, 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 to the one-way valve. Since the one-way valve is designed to allow air to flow only 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 backflow. After being squeezed out, the air will form a slight air current directly blowing on the wound surface. This blowing action helps to keep the wound surface dry, reduce the risk of infection, and also helps to promote blood circulation of the wound surface and speed up the healing process.

[0059] Example 3:

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

[0061] The specific implementation process is as follows: during traction, the temperature sensors installed on the first shell 1 and the second shell 2 begin to monitor the temperature of the wound and the surrounding tissue in real time. The temperature data is transmitted to the controller in real time, and the controller analyzes 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 warning module. The warning module (indicator light and buzzer) will simultaneously issue an audible and visual alarm signal to prompt the operator to pay attention.

[0062] The operator needs to make a comprehensive judgment according to the prompt of the warning module. If the temperature is abnormal, it may be a sign of wound infection, blood circulation disorder, etc. The traction should be stopped immediately, the wound should be checked and appropriate measures should be taken. It also reminds the patient to maintain the appropriate temperature around the wound to avoid an unsuitable environment for wound recovery.

[0063] Example 4:

[0064] The difference from example 3 is that it also includes a remote monitoring module, which is signal connected with the controller. 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 signal connected with a smart terminal (such as a mobile phone, tablet or computer), and medical staff and users can obtain early warning information through the smart terminal in a timely manner.

[0065] The specific implementation process is as follows: connect the remote monitoring module with the controller through wired or wireless methods to ensure 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 communication connection with the smart terminal. Ensure that the smart terminal (such as a mobile phone, tablet computer or computer) can access the network where the remote monitoring module is located.

[0066] Medical staff and users need to install designated monitoring software on the smart terminal. The software should support real-time data reception, display and early warning functions. Configure the address and port number of the remote monitoring module in the monitoring software to receive data. Set the early warning threshold to issue a warning when the data exceeds the normal range. The controller will transmit 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 intelligent terminal. The data can be displayed in the form of charts, curves, etc., which is intuitive and convenient for medical staff and users to observe and analyze. The monitoring software judges whether the data is abnormal according to 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 intelligent terminal. The warning information can include detailed information such as the type, degree, and time of data abnormality. The warning method can be sound, vibration, pop-up window, etc., to ensure that medical staff and users can pay attention to the warning information in time.

[0068] Embodiment 5:

[0069] The difference from embodiment 4 is that a personalized setting module is further included, which is signal-connected with the controller. The personalized setting module is used to adjust the tension threshold, temperature threshold, and warning module through the controller.

[0070] The specific implementation process is as follows: the personalized setting module is connected with the controller through wired or wireless mode, ensuring stable and reliable connection for subsequent data transmission and setting adjustment. The interface and communication protocol of the personalized setting module are configured in the controller, ensuring 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 own needs. When the tension data monitored by the tension sensor reaches or exceeds the set threshold, the warning module will issue a 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 warning module will also issue a warning signal. The personalized setting module also allows medical staff and users to set the warning method of the warning module, such as sound, vibration, pop-up window, etc. Users can choose the appropriate warning method according to their own preferences and needs.

[0072] Specific examples are as follows: medical staff and users first need to enter the personalized setting interface through the intelligent terminal (such as mobile phone, tablet computer, or computer). In the personalized setting interface, users can select the setting item that needs to be adjusted, such as the tension threshold, temperature threshold, or warning module. According to the actual needs, users can adjust the corresponding parameter value through the sliding bar, input box, etc. After adjustment, the user needs to click the save button to save the setting parameters to the controller. After receiving the new setting parameters, the controller 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 example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
