Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a radial fracture treatment brace with a prompting function. Background Technology

[0002] Radial fractures are a common type of upper limb fracture in clinical practice, especially prevalent among the elderly. Currently, for relatively stable radial fractures, conservative treatment usually involves manual reduction followed by external fixation. Traditional fixation methods often use a combination of a splint and bandage. Medical staff first place the splint on the corresponding area of ​​the patient's forearm and wrist, then wrap the splint around the splint to fix it to the limb surface. The number of wraps and the tightness of the bandage depend entirely on the operator's feel and experience.

[0003] In practice, the tightness of the bandage wrapping is difficult to control precisely. If wrapped too tightly, the brace exerts excessive pressure on the patient's arm, potentially affecting local blood circulation and causing swelling, numbness, or even pressure sores. If wrapped too loosely, gaps exist between the brace and the arm, failing to provide effective fixation to the fracture site. This allows the fracture ends to move slightly during activity, thus affecting the quality of healing. Due to the lack of objective quantification of fixation pressure, the tightness varies among different medical personnel, and even the same medical personnel may struggle to maintain consistency across different procedures.

[0004] A bigger problem arises during the home rehabilitation phase after the patient is discharged from the hospital. As the swelling at the fracture site gradually subsides, the circumference of the patient's arm changes, and the gap between the brace and the arm widens. At this time, the previously appropriate fixation pressure becomes insufficient, the brace's restraining effect weakens, and the fracture ends are prone to displacement when the patient unintentionally moves their wrist or forearm. More commonly, patients feel discomfort while wearing the brace and loosen or remove it themselves based on subjective feeling, then adjust and re-wrap it. Lacking an objective basis for judging tightness, patients often tend to wrap it looser than prescribed by the doctor for comfort. This insufficient fixation caused by such actions is frequently seen in clinical practice and is one of the important causes of complications such as fracture redisplacement and malunion.

[0005] On the other hand, some patients, even if they feel the brace is too loose, lack the ability and judgment to adjust it themselves. Elderly people often have weaker hand strength, making it difficult to apply sufficient tension when wrapping the bandage themselves. Some patients also worry that adjusting it themselves will worsen their injury, so even if the brace is noticeably loose, they are afraid or don't know how to re-fix it, and can only wait for medical staff to handle it during their follow-up visit. During this waiting period, the fracture site remains in a state of insufficient fixation, which also negatively impacts healing. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems by providing a radial fracture treatment brace with a prompting function.

[0007] The technical solution of this application is implemented as follows: This application provides a radial fracture treatment brace with a prompting function, the brace comprising: A protective panel assembly, comprising multiple protective panels, wherein the multiple protective panels include at least a first protective panel; A flexible sleeve surrounds and encloses a cylindrical space for a hand to pass through. The flexible sleeve includes: a sleeve body; and accommodating bags disposed around the sleeve body, the accommodating bags extending axially along the cylindrical space and used to accommodate the protective plate assembly. The brace also includes a tightening assembly for tightening the flexible sleeve and the plate assembly to bring the plates together to fix the radius. The tightening assembly is manually operable. The protective gear also includes: A pressure sensor is installed on the surface of the guard plate near the patient's arm to detect the pressure between the guard plate and the arm; A wireless communication module, installed in the protective plate, is used to receive control commands sent by external devices and to send pressure data detected by the pressure sensor to the external devices. A display device is disposed on the surface of the first protective plate away from the patient's arm and is electrically connected to the pressure sensor for outputting prompt information. The display device is also connected to the wireless communication module and can output the control commands. Patients or medical staff can manually operate the tightening component to tighten or release it according to the control commands output by the display device.

[0008] As a further improvement to the above technical solution: The external device is a hospital diagnosis and treatment system, which has a built-in rehabilitation analysis module; The rehabilitation analysis module is used to generate the control instructions based on the pressure data detected by the pressure sensor and the patient's rehabilitation assessment data. The control instructions include suggested release instructions, suggested tightening instructions, and suggested activity limit values.

[0009] As a further improvement to the above technical solution: the external device includes a mobile terminal, on which a mobile APP is installed; The mobile app is used to receive the pressure data sent by the wireless communication module and generate the control command based on the pressure data. The control command is sent to the display device for output through the wireless communication module. The control command includes a suggested release command, a suggested tightening command, and a suggested activity limit value.

[0010] As a further improvement to the above technical solution: the rehabilitation analysis module generates the suggested release command or suggested tightening command including: Obtain the actual pressure value detected by the pressure sensor, and obtain the fracture healing stage parameters from the patient's rehabilitation assessment data; Based on the fracture healing stage parameters, a preset pressure mapping table is consulted to determine the overall recommended pressure value corresponding to the current healing stage; A preset tolerance range is set, which is the allowable pressure fluctuation range centered on the overall recommended pressure value; Compare the current actual pressure value with the overall recommended pressure value: When the current actual pressure value is greater than the upper limit of the preset tolerance range, it is determined that the current pressure is too high, the suggested release command is generated and output through the display device to prompt the patient or medical staff to loosen the tightening component; When the current actual pressure value is less than the lower limit of the preset tolerance range, it is determined that the current pressure is too low, the suggested tightening command is generated and output through the display device to prompt the patient or medical staff to tighten the tightening component. When the current actual pressure value is within the preset tolerance range, the current pressure is determined to be appropriate.

[0011] As a further improvement to the above technical solution: the display device includes a display screen, which is used to display the pressure value detected by the pressure sensor and the control command.

[0012] As a further improvement to the above technical solution: the rehabilitation analysis module generates the suggested activity limit values ​​including: The pressure sensor transmits pressure data to the rehabilitation analysis module via the wireless communication module. The rehabilitation analysis module performs time-domain waveform analysis on the pressure data, establishes a dynamic reference pressure curve, and calculates the fluctuation of the real-time pressure signal relative to the dynamic reference pressure curve. Based on the amplitude and duration characteristics of the fluctuation, the monitored activity events are classified into Category I activity events and Category II activity events: The first type of activity event is defined as the peak amplitude of the fluctuation is less than or equal to a preset first amplitude threshold, and / or the duration of the fluctuation is less than or equal to a preset first time threshold. This type of event is excluded from the record of the number of activities. The second type of activity event is defined as one in which the peak amplitude of the fluctuation is greater than the first amplitude threshold and the duration of the fluctuation is greater than the first time threshold. This type of event is included in the activity count limit. The rehabilitation analysis module also accumulates and counts the second type of activity events, and generates the suggested activity limit value based on the accumulated count result and the preset activity frequency limit value; The first amplitude threshold is twice the root mean square value of the pressure fluctuation under resting conditions.

[0013] As a further improvement to the above technical solution: the rehabilitation analysis module also has a built-in stage mapping submodule, which determines the upper limit of the number of activities based on the patient's current fracture healing stage parameters; The fracture healing staging parameters are values ​​based on normalized imaging assessment data or clinical healing days, and their range is from 0 to 1. The value range of the fracture healing stage parameters is divided into three intervals in ascending order of value: the first interval, the second interval, and the third interval, which correspond to the early, middle, and late stages of fracture healing, respectively. The stage mapping submodule uses a segmented mapping rule to determine the upper limit of the number of activities: When the fracture healing stage parameter is within the first interval, the upper limit of the number of activities is set to a first preset value; When the fracture healing stage parameter is in the second interval, the upper limit of the number of activities increases linearly with the increase of the fracture healing stage parameter; When the fracture healing stage parameter is in the third interval, the upper limit of the number of activities is set to the second preset value; Wherein, the second preset value is greater than the first preset value; Furthermore, the rehabilitation analysis module also compares the accumulated count of the second type of activity events on the same day with the upper limit of the number of activities to calculate the remaining available number of activities. When the remaining available number of activities is less than a preset proportion of the upper limit of the number of activities, the suggested activity limit value includes an activity volume warning indicator.

[0014] As a further improvement to the above technical solution: the wireless communication module includes a Bluetooth communication module or an RFID communication module; The protective gear establishes a two-way wireless communication connection with the external device through the wireless communication module to upload the pressure data and issue the control commands.

[0015] As a further improvement to the above technical solution: the guard plate includes a straight portion and an arc-shaped bend portion, the straight portion extending axially along the cylindrical space to fit the patient's arm, and the arc-shaped bend portion fitting the patient's wrist; the guard plate assembly includes: A first guard plate and a second guard plate arranged opposite to each other, and side guard plates respectively arranged on both sides of the circumference of the cylindrical space; The arc-shaped bends of the first and second protective plates bend toward each other to fit the back and palm of the patient's hand, respectively. The arc-shaped bends of the side guards are bent along both sides of the circumference of the cylindrical space to fit the ulnar and radial sides of the patient's wrist, respectively. The pressure sensor is disposed between the arc-shaped bend and the straight section of the first protective plate; The tightening component includes: A pull rope is wrapped around the outside of the sleeve body; A rotating button is installed on the sleeve body, and the two ends of the pull cord are respectively connected to the rotating button; The rotating button is used to retract the pull cord so that the guard plates are pressed together to fix the radius. The rotating button is equipped with a Hall effect gear encoder, which is used to detect the rotation angle of the adjustment disc of the rotating button. The Hall effect gear encoder is connected to the display device through a wire and is used to convert the rotation angle into the current gear value and transmit it to the display device for output.

[0016] As a further improvement to the above technical solution, the display device also includes an LED indicator light, which is used to indicate the current pressure status with color.

[0017] The advantages or beneficial effects of the above technical solutions include at least the following: The radial fracture treatment brace provided in this application has the following advantages over the prior art.

[0018] This approach utilizes pressure sensors embedded in the brace to achieve real-time detection of the contact pressure between the brace and the arm. Compared to traditional methods that rely on tactile experience, patients can obtain objective pressure data as a basis for adjustment, avoiding overly tight or loose fixation due to subjective judgment bias.

[0019] Compared to existing solutions that only provide pressure readings, this solution uploads pressure data to external devices via a wireless communication module. The hospital's rehabilitation analysis module or mobile app then generates targeted adjustment instructions based on the patient's current fracture healing stage. Patients receive clear instructions such as "loosen" or "tighten," eliminating the need to interpret the pressure readings or possess specialized medical knowledge to make the correct adjustments. This effectively solves the problem of patients not knowing which direction to adjust.

[0020] For patients who are hesitant to adjust the brace themselves for fear of worsening their injury, the instructions displayed on the device come from the hospital's diagnostic system or mobile app, providing clear professional guidance. Patients can simply follow the instructions to restore the brace to a suitable, fixed position, eliminating the psychological burden of self-judgment and manipulation. Throughout the process, patients only need to execute the instructions provided by the display device and do not need to worry about whether their actions are correct.

[0021] For elderly patients with weak hand strength or difficulty in operation, the tightening component used in this solution tightens the bandage by rotating a button and pulling a cord. The operation can be completed simply by turning a knob, which is more effortless and convenient than traditional bandage wrapping methods. Patients do not need to apply much pulling force or have any wrapping skills to adjust the tightness of the protective gear. Attached Figure Description

[0029] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0030] A radial fracture treatment brace with a prompting function can be used to treat fractures in the distal radius, mid-radius, and other locations. Please refer to... Figure 1 , Figure 2 and Figure 3The protective gear mainly includes a panel assembly 10, a flexible sleeve 20, and a tightening assembly 30. The panel assembly 10 contains multiple panels that form the rigid support frame of the protective gear. The flexible sleeve 20 surrounds itself to form a cylindrical space through which the patient's hand and forearm can pass. Multiple panels are distributed circumferentially on the flexible sleeve 20 along the cylindrical space, and each panel is connected to the flexible sleeve 20 as a whole.

[0031] The brace assembly 10 consists of multiple braces that wrap around the patient's forearm and wrist during use. In one embodiment, the brace assembly 10 includes a first brace 11, a second brace 12, and two side braces 13. The first brace 11 is positioned on the back of the patient's hand, the second brace 12 is positioned on the palm side, and the two side braces 13 are positioned on the ulnar and radial sides of the forearm, respectively. Each brace is made of a material with a certain degree of rigidity, such as a polymer or lightweight alloy, which provides sufficient support to fix the fracture site without placing an excessive burden on the patient. Each brace has a straight portion and an arc-shaped bend portion. The straight portion extends axially along the cylindrical space to conform to the straight section of the patient's forearm; the arc-shaped bend portion is located at the end near the palm, and its curvature conforms to the natural curvature of the patient's wrist.

[0032] Please refer to Figure 1 The flexible sleeve 20 includes a sleeve body 21 and receiving pockets 22. The sleeve body 21 is made of flexible fabric and forms a cylindrical structure, which can be directly slipped onto the patient's forearm and wrist. Multiple receiving pockets 22 are provided and fixed around the sleeve body 21, each extending axially along the cylindrical space. In one example, four receiving pockets 22 are positioned at different circumferential locations on the sleeve body 21, corresponding to the back of the hand, the palm side, the ulnar side, and the radial side, respectively. During use, the first protective plate 11, the second protective plate 12, and the two side protective plates 13 are inserted into their respective receiving pockets 22. Each protective plate is inserted inside its corresponding receiving pocket 22, which covers and encloses it, thus defining the position of the protective plate and preventing its edges from directly contacting the patient's skin.

[0033] During actual assembly, operators can select different hardness or size of splints to insert into the receiving pocket 22 according to the specific location of the patient's fracture and fixation requirements. For example, patients with distal radius fractures can choose shorter splints to avoid the splints extending too far and affecting the movement of the metacarpophalangeal joints; while patients with midshaft radius fractures can choose longer splints to provide a more adequate range of fixation.

[0034] The flexible sleeve 20 also features a cushioning pad on its inner side. This cushioning pad can be made of sponge or memory foam and is fitted to the inner surface of the sleeve body 21. When the tightening component 30 pulls the protective plate taut against the patient's limb, the cushioning pad can disperse and buffer the pressure transmitted from the plate. For patients with sensitive skin or fractures accompanied by swelling, the cushioning pad prevents discomfort caused by excessive local pressure concentration and can also absorb minor vibrations generated during daily activities, making the wearing process more comfortable.

[0035] The brace also includes a tightening assembly 30, which tightens the flexible sleeve 20 and the guard plate assembly 10, bringing the guard plates close together to form a stable external fixation for the radius fracture site. The tightening assembly 30 can be manually operated by the patient or medical staff to adjust the tightness as needed.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment, the tightening assembly 30 includes a pull cord 31 and a rotating button 32. The pull cord 31 is wrapped around the outside of the sleeve body 21 and arranged circumferentially around the brace. The rotating button 32 is mounted on the sleeve body 21, and both ends of the pull cord 31 are connected to the retractable end of the rotating button 32. The rotating button 32 adopts a knob-type tightening structure. When in use, after the patient puts the brace on the forearm and wrist, they rotate the knob of the rotating button 32 by hand, and the rotating button 32 will gradually retract the pull cord 31. During the shortening of the pull cord 31, the sleeve body 21 is tightened, and the tightening force is transmitted to each guard plate through the receiving pocket 22, so that the circumferential distance between each guard plate gradually decreases, and finally each guard plate fits tightly against the surface of the patient's arm and wrist. The entire tightening process is controlled by the patient. If it feels too tight, the patient can rotate in the opposite direction to loosen it appropriately; if the fixation is not secure enough, the patient can continue to rotate in the forward direction to tighten it further. The patient can adjust it in real time according to their own feelings.

[0037] As an alternative implementation, the mounting position of the rotating button 32 on the protective gear is not limited to the surface of the sleeve body 21. The rotating button 32 can also be fixedly mounted on one of the protective plates of the protective plate assembly 10, for example, on the outer surface of the first protective plate 11 or the second protective plate 12. When this mounting method is used, the knob portion of the rotating button 32 passes through the fabric of the sleeve body 21 and extends from the outside of the sleeve body 21, allowing the patient to hold and rotate it. The retractable end of the rotating button 32 is connected to both ends of the pull cord 31 through a through hole or threading channel on the sleeve body 21. This design of mounting the rotating button 32 on the protective plate provides a rigid mounting base for the rotating button 32 during operation. Compared to mounting on flexible fabric, the protective plate as a mounting base provides more stable support, and the rotating button 32 will not wobble or shift due to fabric deformation during operation, resulting in a more solid operating feel. Especially when the pull cord 31 is tightened to a greater tension, the guard plate installation method can more effectively transfer the tightening force to each guard plate, reduce the force transmission loss caused by fabric deformation, and make the tightening process more efficient. At the same time, the knob part protrudes from the sleeve fabric, and the patient can directly touch and operate the knob from the outside of the protective gear without having to flip open or adjust the position of the sleeve.

[0038] Regarding the setting of the rotating button 32, this application provides two different implementation schemes.

[0039] In one implementation scheme, please refer to Figure 1 and Figure 2 Two rotating buttons 32 are provided, located at opposite ends of the same side of the flexible sleeve 20. One is closer to the proximal end of the brace, near the elbow, and the other is closer to the distal end, near the palm. During use, the two rotating buttons 32 operate independently, each controlling its corresponding pull cord segment 31. The proximal rotating button 32 primarily tightens the brace in the forearm area, while the distal rotating button 32 primarily tightens the brace in the wrist area. This segmented tightening design offers significant convenience in practical use. Different patients have different forearm and wrist ratios; some patients have well-developed forearm muscles and relatively thin wrists, while others are the opposite. By operating the two rotating buttons 32 separately, patients can achieve their optimal tightness in the forearm and wrist areas respectively. For example, a patient who has been engaged in physical labor for a long time may have relatively strong forearm muscles and a relatively slender wrist. In this case, the proximal rotating button 32 can be loosened appropriately to accommodate the thicker forearm, while the distal rotating button 32 can be tightened appropriately to ensure the fixation effect in the wrist area. This achieves precise adjustment in different areas and avoids a situation where one area is too tight and another is too loose.

[0040] In another implementation, please refer to Figure 3There is only one rotating button 32, which is installed in the middle of the side of the flexible sleeve 20. A pull cord 31 starts from this rotating button 32, circles around the circumference of the brace, and returns to the rotating button 32. When the patient rotates this single rotating button 32, the pull cord 31 contracts synchronously, causing all the plates on the entire brace to move towards the center at the same time. This single rotating button design reduces the number of parts, making the overall structure simpler and the weight of the brace lighter. For patients with limited hand mobility or difficulty operating with one hand, only one rotating button 32 needs to be operated to tighten and fix the entire brace, making the operation simpler and more direct, eliminating the need to adjust multiple parts separately, and reducing the difficulty of daily wear.

[0041] The rotary button 32 is equipped with a Hall effect speed encoder. This encoder detects the rotation angle of the adjustment disc and converts it into a corresponding speed value. This speed value is transmitted to a display screen via a wire, allowing patients or medical staff to clearly see the current speed setting when operating the rotary button 32, facilitating proper control of the tightening level. The Hall effect speed encoder uses a non-contact detection method, offering better durability and reliability compared to traditional mechanical encoders, and is less prone to wear or poor contact issues in scenarios with frequent adjustments.

[0042] The protective gear is also equipped with a pressure sensor to detect the pressure between the protective plate and the patient's arm when the tightening assembly 30 tightens the flexible sleeve 20 and the protective plate assembly 10. The pressure sensor can be a thin-film type, which will not cause the patient any foreign body sensation. This pressure sensor is located on the inner surface of the protective plate, near the patient's arm, and is used to detect the contact pressure between the protective plate and the patient's arm. This location, between the protective plate and the patient's skin, allows the detected pressure value to accurately reflect the actual fixation pressure. When the protective gear is tightened, the pressure between the inner surface of the protective plate and the skin of the arm increases, and the pressure value detected by the pressure sensor rises accordingly; when the protective gear is loosened, the detected pressure value decreases accordingly.

[0043] In one embodiment, a pressure sensor is disposed on the inner surface of the first protective plate 11, specifically in the transition area between the curved and straight portions of the first protective plate 11. This location corresponds to the area near the patient's wrist, a region highly sensitive to pressure between the protective plate and the arm, and can effectively reflect the tightness of the entire protective gear. The pressure sensor can be embedded in the inner surface of the protective plate or attached to the cushioning pad on the inner side of the protective plate, ensuring that only a thin layer of cushioning material separates the sensor from the patient's skin to guarantee detection accuracy. During the wearing of the protective gear, the patient gradually tightens the pull cord 31 by rotating the button 32, and the contact pressure between the protective plate and the arm gradually increases accordingly. The pressure sensor can detect this pressure value in real time and provide feedback to the patient. This is of practical significance for fracture fixation; insufficient fixation pressure may cause micromovement at the fracture ends, affecting the stability of fracture healing; excessive fixation pressure may compress blood vessels and affect blood circulation. Through real-time monitoring by the pressure sensor, the patient can control the pressure within a safe and effective range under the guidance of medical personnel.

[0044] The protective gear also includes a display device. This display device is mounted on the outer surface of the protective plate, away from the patient's arm, and is used to output prompts for easy viewing by the patient or medical staff. In one embodiment, the display device is located on the outer surface of the first protective plate 11. The display device is electrically connected to a pressure sensor via wires to output prompts. The display device is also connected to a wireless communication module and can output control commands received by the wireless communication module. This display device can be implemented in various ways to accommodate different patients' usage habits and visual conditions, specifically including the following two implementation methods.

[0045] In the first embodiment, the display device includes a display screen. This screen is electrically connected to the pressure sensor via wires and can display the pressure value detected by the pressure sensor in real time. The display screen can be a small LCD screen, powered by a button battery, resulting in low power consumption. For elderly patients with poor eyesight, the display screen can use a larger font design for easier reading. This allows patients to check the current pressure value between the brace and their arm at any time while wearing the brace, determining whether the brace is too tight. For example, when a patient feels increased swelling in their arm, they can observe whether the pressure value on the display screen is too high, thus deciding whether to loosen the brace. The display screen is also connected to a wireless communication module. When the hospital's diagnostic system or mobile app issues adjustment commands, the display screen will simultaneously output the command content, such as displaying text prompts like "Recommended to loosen" or "Recommended to tighten," and can also display the degree of deviation between the current pressure value and the recommended pressure value.

[0046] In the second embodiment, the display device includes a set of LED indicator lights to indicate the pressure status. This embodiment has a simpler structure and lower cost, making it particularly suitable for elderly patients with poor eyesight or those who are not accustomed to reading digital displays. The LED indicator lights are located on the outer surface of the first guard plate 11 and are electrically connected to the pressure sensor via wires. When the patient operates the rotating button to tighten or loosen the brace, the LED indicator lights illuminate with different colors according to the current pressure value detected by the pressure sensor to indicate the current tightness. Specifically, when the pressure between the guard plate and the arm is within a suitable range, the LED indicator light illuminates green, indicating that the current tightness is moderate and the patient does not need to make adjustments. When the pressure value is higher than the upper limit of the suitable range, the LED indicator light illuminates red, indicating that the brace is too tight and the patient should loosen the rotating button to release some pressure. When the pressure value is lower than the lower limit of the suitable range, the LED indicator light illuminates yellow, indicating that the brace is too loose and the fixation effect is insufficient, and the patient needs to tighten the rotating button appropriately.

[0047] In this LED indicator light implementation, the display device does not show the specific pressure value in real time. Patients only need to observe the color of the light to quickly determine the current tightness. Green indicates everything is normal, red indicates it needs to be relaxed, and yellow indicates it needs to be tightened. The meanings of the three colors are simple and clear, requiring no special memorization or understanding. When an elderly patient is wearing a brace, after each adjustment of the rotating button, they only need to glance down at the light color on the brace to confirm that it is green before continuing their activities. When swelling occurs in the arm, causing the brace to tighten, the LED indicator light automatically switches from green to red. Even if the patient does not feel obvious discomfort, seeing the red light indicates that the brace needs to be loosened, thus avoiding prolonged pressure. When the swelling subsides and the brace loosens, the light switches from green to yellow. Seeing the yellow light allows the patient to tighten it promptly, ensuring that the fracture site remains stably fixed.

[0048] LED indicator lights have a practical advantage over displays: they don't rely on the patient's visual acuity. For elderly people with poor eyesight, small numbers on a display screen may be difficult to read, but the large-area color indications of LED indicator lights do not present this problem. Even without reading glasses, patients can clearly distinguish red, yellow, and green. Furthermore, LED indicator lights are clearly visible in strong outdoor light, unaffected by direct sunlight, while LCD screens often suffer from glare under strong light, making reading difficult.

[0049] In another embodiment, the display device may include both a display screen and LED indicator lights. The display screen shows the specific pressure values ​​and textual instructions for patients or medical staff to view in detail; the LED indicator lights provide quick status indications, allowing patients to quickly understand the general situation by glancing at the light color during daily use, and then carefully check the specific values ​​on the display screen when the light is abnormal. The two indication methods complement each other, meeting the needs of different scenarios. For example, patients mainly rely on the color of the LED indicator lights to quickly confirm their status during daytime activities, while during follow-up visits, they can use the display screen to show doctors specific pressure data and historical records.

[0050] For elderly patients unfamiliar with smartphone operation, or those who wish to share their data with family members, the mobile app also supports data sharing. Patients can authorize the sharing of their stress and activity data with designated family members or caregivers, who can then remotely view it on their own phones. This way, even if the patient doesn't pay much attention to the notifications on their phone, family members can promptly notice any abnormalities and remind the patient to adjust their protective gear. For example, the daughter of an elderly patient living alone, who works in another city, can use the app's sharing function to check her father's stress data from his protective gear at any time. If she finds that the stress level is consistently high, she can proactively call her father to remind him to loosen the protective gear, preventing discomfort or complications caused by the patient ignoring the notifications.

[0051] The protective gear also features a wireless communication module. This module, installed inside or on the surface of the protective plate, communicates with external devices. It can transmit pressure data detected by pressure sensors to these devices and receive control commands from them. These commands include suggested actions based on the patient's current condition, such as release, tightening, and activity limits. A display device connected to the wireless communication module outputs the received commands for the patient or healthcare personnel to reference.

[0052] In one embodiment, the wireless communication module uses a Bluetooth communication module, enabling the protective gear to establish a two-way wireless communication connection with the hospital's diagnostic and treatment system. Bluetooth communication is characterized by low power consumption and stable connection, making it suitable for wearable device applications such as protective gear. In another embodiment, the wireless communication module uses an RFID communication module, exchanging data with the hospital's diagnostic and treatment system via near-field communication. The wireless communication module uploads pressure data collected by the pressure sensor to the hospital's diagnostic and treatment system in real time, while simultaneously receiving control commands from the system. This allows hospital staff to remotely access patients' protective gear usage data and provide timely adjustment suggestions based on data changes.

[0053] The hospital's diagnostic and treatment system has a built-in rehabilitation analysis module. This module can generate control commands based on pressure data detected by pressure sensors and the patient's rehabilitation assessment data. As an optional implementation, the aforementioned external device is not limited to the hospital's diagnostic and treatment system. In another embodiment, the external device takes the form of a mobile app, which is installed on the patient's mobile terminal, such as a smartphone or tablet. The mobile app establishes a two-way communication connection with the protective gear via a wireless communication module, and can also receive pressure data uploaded by pressure sensors, and generate control commands based on this data to be sent to the protective gear's display device for output.

[0054] When using the brace daily, patients can simply open the app on their mobile phones to view the real-time pressure readings between the brace and their arm, as well as the pressure trends over a period of time. The app also includes a simplified rehabilitation analysis function. Before using the brace, patients can enter their basic information and fracture details into the app, such as fracture type, injury time, and whether the treatment plan was surgical or conservative. Based on this information, the app provides an initial recommended pressure range. As rehabilitation progresses, patients can enter their doctor's assessment results into the app after each follow-up visit. The app then dynamically adjusts the recommended pressure values ​​accordingly, ensuring the adjustments better match the patient's current healing stage.

[0055] For example, a young patient was discharged from the hospital wearing a brace after fracture surgery. The hospital provided the brace and instructed him to install a companion app on his phone. Once home, the brace automatically connected to the app via Bluetooth. When the patient adjusted the rotating buttons, the display showed the pressure value in real time, which was simultaneously displayed on the app. The app interface used colors to differentiate the current pressure range: green indicated appropriate pressure, yellow indicated too low or too high, and red indicated a significant deviation from the recommended range. The patient could intuitively judge the appropriate tightness based on the color indicators, without needing to memorize specific pressure ranges.

[0056] The mobile app also has recording and statistical functions. Each time a patient adjusts the braces, the app records the pressure values ​​before and after the adjustment, as well as the adjustment time, creating a complete wearing log. During follow-up appointments, patients can directly show the records from the app to their doctors, allowing doctors to understand the patient's use of the braces during home rehabilitation, including whether there were prolonged periods of excessive or insufficient pressure, and trends in the patient's activity levels. This data provides doctors with objective evidence to adjust the rehabilitation plan.

[0057] For elderly patients unfamiliar with smartphone operation, or those who wish to share their data with family members, the mobile app also supports data sharing. Patients can authorize the sharing of their stress and activity data with designated family members or caregivers, who can then remotely view it on their own phones. This way, even if the patient doesn't pay much attention to the notifications on their phone, family members can promptly notice any abnormalities and remind the patient to adjust their protective gear. For example, the daughter of an elderly patient living alone, who works in another city, can use the app's sharing function to check her father's stress data from his protective gear at any time. If she finds that the stress level is consistently high, she can proactively call her father to remind him to loosen the protective gear, preventing discomfort or complications caused by the patient ignoring the notifications.

[0058] Mobile apps serve as an alternative to external devices, complementing hospital diagnostic systems. For medical institutions already equipped with such systems, the protective gear can be directly integrated for automated remote monitoring and intervention. For settings without such systems or where patients have been discharged, the mobile app provides equally effective control functions, allowing patients to receive similar guidance without relying on hospital-based equipment. Both solutions share the same protective gear hardware, requiring only adaptive configuration at the wireless communication module interface level for switching between them.

[0059] Rehabilitation assessment data can include information such as fracture healing stage parameters, which can be determined based on imaging assessment results or clinical healing days. The rehabilitation analysis module processes and analyzes the received pressure data, combines it with the patient's current healing stage, generates targeted control instructions, and sends them to the display screen of the brace via a wireless communication module.

[0060] Regarding pressure regulation, the rehabilitation analysis module generates suggested release or tightening instructions as follows: First, the module acquires the actual pressure value detected by the pressure sensor, and simultaneously obtains the fracture healing stage parameters from the patient's rehabilitation assessment data. Based on the fracture healing stage parameters, the module queries a preset pressure mapping table to determine the overall recommended pressure value corresponding to the current healing stage. Different healing stages require different fixation pressures; for example, relatively stable fixation is needed in the early stages of fracture healing, while the pressure requirements can be appropriately relaxed as healing progresses.

[0061] The rehabilitation analysis module pre-sets a tolerance range, which is an allowable pressure fluctuation range centered on the overall recommended pressure value. When the actual pressure value of the brace falls within this range, the current fixation pressure is considered appropriate. When the actual pressure value exceeds the upper limit of the tolerance range, it indicates that the brace is applying too much pressure to the arm. In this case, the module generates a suggested release command, which is displayed on the screen, prompting the patient or medical staff to loosen the tightening components. When the actual pressure value is below the lower limit of the tolerance range, it indicates that the brace is not tight enough, potentially posing a risk of fracture displacement. In this case, the module generates a suggested tightening command, prompting the patient or medical staff to tighten the tightening components.

[0062] When a patient first wore a brace after a fracture, the brace's fixation pressure was within a suitable range because there was no significant swelling in the arm. The display device indicated that the pressure was normal, and the patient could continue wearing it in the current tightened state. As time went on, the arm began to swell, and the pressure between the brace and the arm gradually increased. When the pressure value exceeded the upper limit of the tolerance range, the display device output a prompt to release the pressure. The patient then adjusted the rotating button according to the prompt, and the pressure value returned to a suitable range, at which point the prompt disappeared.

[0063] For example, during the swelling subsides, the patient may notice a decrease in arm circumference, and the contact between the brace and the arm becomes less tight. At this time, the pressure reading displayed on the device remains low, and soon a prompt to tighten it will appear. The patient should follow the prompts and rotate the knob to tighten the brace appropriately until the pressure reading displayed on the device returns to the normal range, and the brace regains a stable fixation.

[0064] For example, a patient might involuntarily flex and extend their arm during sleep, causing momentary fluctuations in pressure between the arm support and the arm. Although the patient may not be aware of these movements, the pressure sensor detects the corresponding signal changes. If the amplitude and duration of these movements exceed the normal range, the rehabilitation analysis module will include them in the activity event statistics. The next day, when the patient checks the display device, they can see the system's activity level prompts, thus understanding their activity from the previous night and consciously controlling the intensity of their activities during the day's rehabilitation training.

[0065] Regarding activity restrictions, the rehabilitation analysis module generates suggested activity restriction values ​​as follows: Pressure sensors transmit pressure data to the rehabilitation analysis module via a wireless communication module. The rehabilitation analysis module performs time-domain waveform analysis on this pressure data. Specifically, the module establishes a dynamic baseline pressure curve, which reflects the basic level of the patient's pressure signal at rest. The module then calculates the fluctuation of the real-time pressure signal relative to this dynamic baseline pressure curve.

[0066] Based on the amplitude and duration characteristics of the fluctuation volume, the rehabilitation analysis module categorizes the monitored activity events into two types. The first type refers to activities with small peak amplitudes and short durations. These activities typically correspond to minor daily movements, such as slight finger flexion and extension or minor adjustments to arm position. These movements do not adversely affect fracture healing and are therefore not included in the activity count. The second type refers to activities with large peak amplitudes and long durations. These activities typically correspond to more pronounced movements, such as wrist flexion and extension or forearm rotation. These movements may exert stress on the fracture site and need to be restricted.

[0067] The rehabilitation analysis module accumulates and counts the second type of activity events, and generates suggested activity limits based on the accumulated count and a preset activity limit. The activity limit can be determined based on the patient's current fracture healing stage parameters; the limit is lower in the early healing stage and can be appropriately relaxed in the middle and late stages. When the patient's daily activity count approaches or reaches the limit, an activity warning indicator will appear on the display screen, reminding the patient to reduce unnecessary activities and avoid adverse effects on fracture healing.

[0068] In one embodiment, the first amplitude threshold is set to twice the root mean square value of pressure fluctuation at rest. This threshold can be dynamically adjusted based on individual patient differences, making the classification of activity events more closely reflect the patient's actual situation. The first time threshold is determined based on the statistical value of the duration of a normal fist-clenching action, used to distinguish between brief movements and continuous activities.

[0069] During the early stages of rehabilitation, a patient wearing a brace experienced occasional activity level warnings on the monitoring device while performing daily activities. The patient noticed that when standing or walking, their arm would swing slightly with the body, but these swings did not trigger activity counting and therefore did not deplete their daily activity limit. However, when the patient attempted to reach for a glass of water on a table with their affected hand, the wrist flexion and extension movements triggered a Type II activity event, causing the activity count on the monitoring device to increase. Based on this, the patient understood which movements were counted within their activity limit and consciously reduced the frequency of these movements in subsequent daily activities.

[0070] In another scenario, a patient in the middle of rehabilitation is allowed to perform appropriate wrist flexion and extension exercises. Following the rehabilitation plan, the patient performs several exercises daily, with the activity count on the display device increasing after each exercise. When the count approaches the daily limit, the display device provides a prompt, allowing the patient to end the day's training to avoid overexertion that could hinder healing. The count resets the following day, allowing the patient to continue training according to the plan.

[0071] The stage mapping submodule determines the upper limit of activity frequency based on the patient's current fracture healing stage parameters. The fracture healing stage parameters are values ​​normalized from imaging assessment data or clinical healing days, ranging from 0 to 1. This value can be divided into three intervals, corresponding to the early, middle, and late stages of fracture healing. In the early stage, the upper limit of activity frequency is set to a lower first preset value to ensure stable healing of the fracture site. In the middle stage, the upper limit of activity frequency increases linearly with the healing stage parameter, allowing the patient to gradually increase their activity level. In the late stage, the upper limit of activity frequency is set to a higher second preset value, at which point the fracture has largely healed, and the patient can engage in more substantial rehabilitation activities.

[0072] During the first week's follow-up, imaging assessments showed a clear fracture line, and the healing stage parameters were in the first interval. The maximum number of movements indicated on the brace display was only a few. The patient's daily activities were severely limited; aside from essential daily routines, the arm was essentially kept still. By the fourth week's follow-up, imaging showed a blurred fracture line, good callus formation, and the healing stage parameters had entered the second interval. The system automatically increased the daily activity limit. The patient noticed a significant relaxation in the warning threshold on the display and began gentle wrist joint exercises as instructed by the therapist. By the eighth week, the healing stage parameters had entered the third interval, and the maximum number of movements had further increased. The patient could now use the affected hand for daily activities almost normally, only needing to avoid lifting heavy objects.

[0073] Please refer to Figures 4 to 7 The protective plate assembly 10 includes a first protective plate 11 and a second protective plate 12 arranged opposite to each other, and side protective plates 13 respectively disposed on both sides of the cylindrical space. The first protective plate 11 and the second protective plate 12 are arranged vertically opposite each other. The arc-shaped bending portion of the first protective plate 11 bends towards the arc-shaped bending portion of the second protective plate 12, that is, the bending portion of the first protective plate bends towards the palm, and the bending portion of the second protective plate bends towards the back of the hand, respectively adapting to the curvature of the back of the hand and the palm of the hand. Specifically, the arc-shaped bending portion of the first protective plate 11, corresponding to the back of the hand, bends towards the palm to conform to the physiological curvature of the back of the hand; the arc-shaped bending portion of the second protective plate 12, corresponding to the palm, bends towards the back of the hand to conform to the natural concavity of the palm. The two side protective plates 13 are respectively disposed on the left and right sides, and the arc-shaped bending portion of each side protective plate 13 bends along the direction of its respective side to match the contour shape of both sides of the wrist, that is, respectively adapting to the ulnar side and the radial side of the patient's wrist.

[0074] Please refer to this carefully. Figure 8When viewed from a horizontal angle on the side of the brace, the curved section and the straight section of the side plate 13 form a downward-sloping obtuse angle A. This obtuse angle A allows the curved section of the side plate 13 to conform to the natural anatomical direction of the ulnar and radial sides of the wrist. The ulnar and radial styloid processes on both sides of the wrist are prominent bony landmarks. The straight edges of traditional braces can easily press directly against these protruding areas, causing local pain and even skin abrasion with prolonged wear. The obtuse angle A of the side plate 13 effectively avoids the locations of the ulnar and radial styloid processes, preventing the edge of the plate from directly compressing the bony protrusions, thus reducing local discomfort while ensuring effective fixation.

[0075] The first protective plate 11 has a downward-sloping first bend 111 at its end near the palm. This first bend 111 is tilted towards the palm side, and when the protective gear is in place, this bend is located precisely on the dorsal side of the metacarpophalangeal joint. The metacarpophalangeal joint is a crucial part of finger movement; everyday grasping and extending movements rely on its normal motion. The downward slope of the first bend 111 ensures that the edge of the protective plate avoids the range of motion of the metacarpophalangeal joint, allowing the patient to move their fingers relatively freely while wearing the protective gear. This design effectively helps maintain blood circulation in the hand and prevent joint stiffness, preventing patients from experiencing inconvenience due to the protective plate obstructing their daily activities.

[0076] For the second protective plate 12, this application provides three different implementation schemes to accommodate the different anatomical characteristics and different fracture fixation needs of different patients.

[0077] Please refer to Figure 4 , Figure 5 and Figure 6 In the first embodiment, the second guard plate 12 has a first curved section 121 and a second curved section 122 connected in sequence at the end near the palm. The first curved section 121 is located near the main body of the guard plate, and its curvature is towards the hand, that is, protruding towards the palm side. The palm of the human body is not completely flat, but presents a natural arc-shaped depression. The protrusion of the first curved section 121 conforms to this depression shape, allowing the guard plate to fit tightly against the palm area without gaps. The second curved section 122 is connected to the end of the first curved section 121, and its curvature is opposite to that of the first curved section 121, bending away from the hand. During wrist flexion and extension movements, a movable wrinkle area appears on the palm side. If the edge of the guard plate extends into this area, it will restrict the normal movement of the wrist joint. The second bending segment 122 bends away from the hand, which is equivalent to making way for the edge of the brace to move further away, leaving enough space for the flexion and extension of the wrist joint. The patient can still perform a certain range of flexion and extension movements of the wrist while wearing the brace.

[0078] Please refer to Figure 9 In the second embodiment, the end of the second guard plate 12 closest to the palm has only a second curved section 122 that bends away from the hand, without the first curved section 121. This design is relatively simple and suitable for patients with inconspicuous palm concavity or those who do not require a high degree of palm fit. The separately provided second curved section 122 can also avoid the wrist joint's range of motion, ensuring that the patient's wrist can move normally while wearing the brace.

[0079] Please refer to Figure 10 In the third embodiment, the end of the second guard plate 12 closest to the palm is a straight section, without any curved structure. This solution is the simplest and easiest to manufacture, and is suitable for cases where the fracture is located relatively high and the guard plate does not need to extend to the wrist joint area. When the fracture occurs in the midshaft of the radius or higher, using the straight end of the second guard plate 12 can meet the fixation requirements while avoiding unnecessary material extension.

[0080] The three different structural forms of the second guard plate 12 mentioned above can be selected according to the specific condition of the patient in clinical application. For example, for patients with distal radius fractures who need to restrict excessive wrist joint movement, the first option with a first curved segment 121 and a second curved segment 122 can be selected, which can fit the palm while leaving room for wrist joint movement; for patients with fracture lines that are higher and do not need to extend to the palm, the third option with a straight segment can be selected to simplify the structure of the guard.

[0081] Please refer to Figure 7 From a top-down view, the individual plates of the protective arm assembly 10 are spaced apart circumferentially, with adjacent plates connected by a sleeve body 21. This circumferentially spaced layout allows each plate to apply force towards the center from multiple directions simultaneously when tightened, creating a wrap-around effect. Compared to traditional one-piece cylindrical braces, this split design better adapts to individual differences in limb size among patients. Regardless of whether the patient's forearm is thick or thin, each plate can independently conform to the corresponding limb surface under the action of the tightening component 30.

[0082] The protective plate has wiring channels running along its length inside. The electrical connection wires between the pressure sensor and the display device, as well as between the pressure sensor and the wireless communication module, are all routed through these channels. This wiring method conceals the wires inside the protective plate, avoiding the risk of tangling and inconvenience caused by exposed wires, and also makes the protective gear look cleaner.

[0083] The pressure sensor is connected to the display device via wires, transmitting the detected pressure signal to the display device for output. The pressure sensor is also connected to a wireless communication module via wires, transmitting pressure data to the wireless communication module for uploading. The display device is also connected to the wireless communication module via wires, used to output control commands received by the wireless communication module. The wire connections between the components are simple and reliable, facilitating production and assembly.

[0084] When using the protective gear, the patient first inserts their hand and forearm into the cylindrical space of the flexible sleeve 20, positioning each guard plate in its corresponding position on the back of the hand, palm, ulnar side, and radial side. Then, by operating the rotating button 32, the pull cord 31 is gradually tightened until a suitable fit is achieved between the guard plate and the arm. During this process, the pressure information output by the display device can be viewed to ensure that the protective gear provides sufficient fixation without causing excessive pressure on the arm. After wearing, the pressure sensor continuously monitors the pressure changes between the guard plate and the arm, and the display device outputs the pressure value in real time. The wireless communication module uploads the data to the hospital's diagnostic and treatment system. The rehabilitation analysis module of the hospital's diagnostic and treatment system generates control instructions based on the received data and sends them to the protective gear. The display device outputs the content of the control instructions, and the patient or medical staff makes corresponding adjustments according to the instructions. Throughout the process, the patient can monitor the fixation status of the protective gear and the doctor's advice at any time, eliminating the need for frequent hospital visits. This improves the convenience of rehabilitation and reduces the risk of complications caused by improper tightness of the protective gear.
