Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, specifically to an auxiliary device for rehabilitation treatment of musculoskeletal pain. Background Technology

[0002] Musculoskeletal pain (such as knee osteoarthritis, tennis elbow, and hip synovitis) is a common clinical condition in orthopedics. Rehabilitation treatment needs to address three core needs: stable support, pressure adaptation, and physical therapy intervention, in order to relieve pain, promote local blood circulation, and restore joint function. Currently, rehabilitation assistive devices used clinically and at home are mainly divided into three categories: fixed-size support sleeves, manually adjustable strap-type support devices, and independent physical therapy equipment. However, they generally suffer from the following technical deficiencies, making it difficult to meet the needs of efficient and safe rehabilitation:

[0003] Fixed-size support sleeves can only fit joints of a single circumference. Obese or thin patients are prone to problems such as displacement due to being too loose or pressure sores due to being too tight after wearing them. The contact pressure fluctuations often exceed the safe range. Manually adjustable strap devices rely on the patient's subjective feelings for adjustment, with circumference adjustment errors reaching 1-2cm. They also cannot dynamically adapt with joint movements (such as knee flexion and extension), highlighting the contradiction of support failure during activity and local pressure when at rest.

[0004] Traditional solutions require multiple devices to achieve support, physiotherapy, and monitoring functions—patients need to wear support sleeves, apply heat patches, and fix pressure sensors simultaneously, which involves many steps and is difficult for elderly patients to use alone.

[0005] Traditional support devices often use rigid, integral frames or single curved springs, which cannot adapt to the asymmetrical curvature of joints (such as the patella of the knee joint and the medial and lateral condyles of the femur). The support force is concentrated in a local area, which can easily cause new muscle fatigue and pain, thus affecting the rehabilitation effect.

[0006] Based on the above problems, there is an urgent need for an auxiliary device for musculoskeletal pain rehabilitation that combines dynamic adaptation and functional integration, in order to break through the bottlenecks of traditional technology and improve the safety and effectiveness of rehabilitation treatment. Summary of the Invention

[0007] To address the aforementioned issues, this invention provides an auxiliary device for musculoskeletal pain rehabilitation, used for clinical treatment and home rehabilitation of musculoskeletal pain in multiple locations. Through an integrated design of mechanical linkage and intelligent control, it achieves dynamic and precise adaptation of joint circumference, taking into account support stability, wearing comfort, and ease of operation, meeting the usage needs of patients of different body types in various scenarios such as clinical treatment, home recuperation, and outdoor rehabilitation.

[0008] To achieve the above object, the technical solution of the present invention is as follows: A rehabilitation treatment assistance device for musculoskeletal joint pain, comprising an arc support unit, a circumference adjustment unit for adjusting the circumference of the arc support unit, and a pressure buffer unit for dispersing local pressure to avoid pressure ulcers. A flexible main belt body is sleeved outside the arc support unit. The circumference adjustment unit is installed on the opening side of the arc support unit. The pressure buffer unit is clamped between the arc support unit and the flexible main belt body. A monitoring unit for real-time collecting pressure data and joint movement data of the contact is installed on the inner side of the flexible main belt body. The monitoring unit is signal-connected to a controller for receiving the pressure data and movement data and outputting a control command. The circumference adjustment unit is signal-connected to the controller. The controller is used to regulate the circumference adjustment unit according to the real-time monitoring data of the monitoring unit;

[0009] When the pressure data is greater than the pressure threshold preset in the controller, the controller is used to drive the circumference adjustment unit to increase the circumference;

[0010] When the joint movement data is greater than the movement threshold preset in the controller and the pressure data is less than the pressure threshold preset in the controller, the controller is used to drive the circumference adjustment unit to decrease the circumference.

[0011] Further, the circumference adjustment unit includes a driving member. The driving member is fixedly connected to the arc support unit. The output shaft of the driving member is coaxially and fixedly connected with a screw rod. A nut seat is threadedly connected to the screw rod. An adjustment belt is fixedly connected to the nut seat. The end of the adjustment belt away from the nut seat is connected to the side of the arc support unit away from the driving member, and the driving member is signal-connected to the controller.

[0012] Further, the arc support unit includes a plurality of support bars, flexible connecting pieces and a bionic silica gel layer. The support bars are distributed in a "pin" shape, corresponding to the patella corresponding area, the medial condyle corresponding area and the lateral condyle corresponding area of the joint respectively. The adjacent support bars are hinged by the flexible connecting pieces. The bionic silica gel layer covers the outside of the support bars. The surface of the inner bionic silica gel layer is provided with wavy anti-slip textures.

[0013] Further, the monitoring unit includes a pressure sensor and an angle sensor. The pressure sensor is attached to the side of the flexible main belt body close to the patient's limb skin. The angle sensor is used to detect the flexion and extension angle of the joint. The angle sensor is installed at the flexible connecting piece. Both the pressure sensor and the angle sensor are signal-connected to the controller.

[0014] Furthermore, the pressure buffer unit includes several sets of matrix-type elastic buffer components. Each elastic buffer component includes a conical spring, a buffer pad, and a connecting bracket. The conical spring is installed between the support bar and the flexible main belt. The diameter of the end of the conical spring near the flexible main belt is larger than the diameter of the end of the conical spring near the support bar. The buffer pad is fixedly connected between the conical spring and the support bar. The connecting bracket is fixedly connected between the conical spring and the flexible main belt. When the support bar deforms, the conical spring expands and contracts axially.

[0015] Furthermore, it also includes a physiotherapy unit, which is detachably connected to the flexible main belt. The physiotherapy unit includes a heat therapy module and a low-frequency pulse module. Both the heat therapy module and the low-frequency pulse module are connected to the controller signal. When the pressure data is equal to the pressure threshold and the static time of the joint movement data is greater than the time threshold in the controller, the controller starts the heat therapy module and the low-frequency pulse module.

[0016] Furthermore, the monitoring component also includes a temperature sensor, which is used to monitor the temperature data of the skin during physiotherapy. The temperature sensor is fixedly connected to the inside of the biomimetic silicone layer and is connected to the controller signal.

[0017] Furthermore, it also includes a heat dissipation unit, which includes a cooling fan, an air guide shroud, and heat dissipation holes; the cooling fan is coaxially and fixedly connected to the end of the lead screw away from the drive component, and an air guide channel is opened on the flexible main belt, which is connected to the air outlet of the air guide shroud. The air guide shroud is fitted on the outside of the cooling fan, and the heat dissipation holes include axial heat dissipation holes opened inside the support bar and ventilation holes opened in the biomimetic silicone layer.

[0018] When the temperature data exceeds the preset temperature threshold in the controller, the controller starts the drive to increase the size, and at the same time drives the cooling fan. The airflow enters the air guide channel through the air guide shroud, and then is discharged through the vent and axial heat dissipation holes.

[0019] Furthermore, it also includes an early warning unit, which includes an audible and visual alarm and a vibrator, both of which are connected to the controller signal. When the pressure exceeds the pressure threshold, or the temperature exceeds the temperature threshold, or the joint activity data exceeds the activity threshold, the controller triggers the audible and visual alarm and the vibrator.

[0020] Furthermore, it also includes a power supply unit for supplying power to each unit, a wireless communication module for enabling data interaction and remote control, and a storage module for storing monitoring data and operation records.

[0021] The above approach has the following beneficial effects:

[0022] 1. This solution combines mechanical linkage with intelligent control to achieve dynamic and precise adaptation of joint circumference and curvature. Compared with traditional technologies that use fixed-size support sleeves or manually adjustable straps, traditional devices can only adapt to a single body type or require repeated manual adjustments, which can easily lead to loosening during activity and excessive tightness when at rest. This solution, however, can adjust the circumference to adapt to patients of different body types. The support strip can deform in the direction of the joint curvature, and with the gradient buffer of the conical spring, the contact pressure is always kept within a safe range, effectively avoiding pressure sores and device displacement. It has a wide range of suitable populations and high universality.

[0023] 2. This solution constructs a physiotherapy safety system that integrates temperature monitoring, heat dissipation linkage, and early warning protection, achieving dual protection of therapeutic effects and safety. Compared with traditional technologies that lack temperature-controlled hot compresses or independent heat dissipation devices, traditional devices experience large temperature fluctuations, easily leading to local burns, and require manual activation for heat dissipation, making operation cumbersome. In contrast, this solution uses a temperature sensor to monitor skin temperature in real time. When the temperature approaches the threshold, the controller automatically activates the heat dissipation unit (a lead screw drives the fan to operate synchronously, and the through-flow airflow cools the skin in a short time). At the same time, an early warning unit provides a notification, reducing the risk of physiotherapy burns and maintaining a safe therapeutic environment without manual intervention.

[0024] 3. This solution simplifies the operation process and enables data management through modular design. Compared with traditional technologies that use multiple devices or lack data recording functions, traditional rehabilitation requires wearing support sleeves, physiotherapy devices, and monitoring devices at the same time, which involves many operation steps and makes it impossible to trace rehabilitation data. This solution integrates support, adjustment, physiotherapy, and monitoring functions into one, with automatic adaptation and short processing time. The wireless communication module and storage module enable real-time uploading and storage of pressure, temperature, and joint activity data. The data can be exported for clinical evaluation, greatly reducing the difficulty of operation for patients and the workload of medical staff.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following detailed description illustrates the specific implementation method:

[0035] Example 1:

[0036] As attached Figures 1 to 4Shown: A rehabilitation treatment assistance device for myoarthralgia, including an arc-shaped support unit for conforming to the joint surface and providing support force, a circumference adjustment unit for adjusting the circumference of the arc-shaped support unit, and a pressure buffer unit for dispersing local pressure to avoid pressure ulcers. A flexible main belt body 1 is sleeved outside the arc-shaped support unit. The circumference adjustment unit is installed on the opening side of the arc-shaped support unit. The pressure buffer unit is sandwiched between the arc-shaped support unit and the flexible main belt body 1. The arc-shaped support unit includes several support bars 6, flexible connection pieces 7 and a bionic silica gel layer. The support bars 6 are distributed in a "pin" shape, corresponding to the patella corresponding area, the medial condyle corresponding area and the lateral condyle corresponding area of the joint respectively. The adjacent support bars 6 are hinged by the flexible connection pieces 7. The bionic silica gel layer covers the outside of the support bars 6, and wavy anti-slip textures are provided on the surface of the inner bionic silica gel layer.

[0037] The pressure buffer unit includes several groups of matrix-type elastic buffer components. The elastic buffer components include conical springs, buffer pads and connection card seats. The conical springs are installed between the support bars 6 and the flexible main belt body 1. The diameter of the conical spring at the end close to the flexible main belt body 1 is larger than the diameter of the conical spring at the end close to the support bars 6. The buffer pads are fixedly connected between the conical springs and the support bars 6. The connection card seats are fixedly connected between the conical springs and the flexible main belt body 1. When the support bars 6 deform, the conical springs expand and contract axially.

[0038] A monitoring unit for real-time collecting contact pressure data and joint movement data is installed inside the flexible main belt body 1. The monitoring unit is signal-connected to a controller for receiving the pressure data and movement data and outputting a control command.

[0039] The circumference adjustment unit is signal-connected to the controller. The controller is used to control the circumference adjustment unit according to the real-time monitoring data of the monitoring unit. When the pressure data is greater than the preset pressure threshold in the controller, the controller is used to drive the circumference adjustment unit to increase the circumference. When the joint movement data is greater than the preset movement threshold in the controller and the pressure data is less than the preset pressure threshold in the controller, the controller is used to drive the circumference adjustment unit to decrease the circumference.

[0040] The circumference adjustment unit includes a driving member 2. In this embodiment, the driving member 2 is a motor. The driving member 2 is fixedly connected to the arc-shaped support unit. A lead screw 3 is coaxially and fixedly connected to the output shaft of the driving member 2. A nut seat 4 is threadedly connected to the lead screw 3. An adjustment belt 5 is fixedly connected to the nut seat 4. One end of the adjustment belt 5 away from the nut seat 4 is on the side of the arc-shaped support unit away from the driving member 2. The driving member 2 is signal-connected to the controller.

[0041] The monitoring unit includes a pressure sensor and an angle sensor. The pressure sensor is attached to the side of the flexible main band 1 close to the patient's limb skin. The angle sensor is used to detect the flexion and extension angle of the joint. The angle sensor is installed at the flexible connecting piece 7. Both the pressure sensor and the angle sensor are signal-connected to the controller.

[0042] It also includes a power supply unit for supplying power to each unit, a wireless communication module for realizing data interaction and remote control, and a storage module for storing monitoring data and operation records.

[0043] The specific implementation process is as follows: According to the type of the patient's painful joint (taking the knee joint as an example), confirm that the "pin"-shaped support bars 6 of the arc support unit are respectively aligned with the upper edge of the patella, the medial condyle of the femur and the lateral condyle area. Wrap the flexible main band 1 around the knee joint to initially complete the pre-wearing of the device. At this time, the circumference is in the initial relaxed state. The pressure sensor detects the initial pressure value, and the angle sensor records the initial flexion and extension angle of the joint.

[0044] The controller sends a data acquisition instruction to the monitoring unit. The pressure sensor collects the pressure data of each contact point of the knee joint. The angle sensor synchronously records the current joint angle and determines it as the "static state". At this time, the pressure data are all lower than the pressure threshold, and the controller triggers the circumference adjustment unit to start.

[0045] The controller outputs a forward rotation signal to the driving member 2 (motor). The output shaft of the driving member 2 drives the screw rod 3 to rotate clockwise. The nut seat 4 threadedly connected to the screw rod 3 moves along the axial direction of the screw rod 3 towards the direction close to the driving member 2, thereby pulling the adjustment belt 5 to contract, and the circumference of the arc support unit gradually decreases. During this process, the pulling force of the adjustment belt 5 is transmitted to the support bar 6, causing the support bar 6 to undergo a directional deformation along the knee joint curve. The flexible connecting piece 7 between adjacent support bars 6 is gradually bent with the amount of deformation, ensuring that the support bar 6 always fits the joint contour; at the same time, the conical spring of the pressure buffer unit is compressed synchronously with the deformation amount of the support bar 6. The conical structure with the small end受压 makes the buffer force increase with the deformation amount, and disperses the local pressure to the entire contact area.

[0046] When the pressure sensor detects that the pressures at each point are all stable around the pressure threshold (within the optimal pressure range), it immediately feeds back the data to the controller. The controller outputs a stop signal, and the driving member 2 stops rotating. The screw rod 3 and the nut seat 4 maintain the circumference stability through thread self-locking, and the initial adaptation is completed. At this time, the anti-slip texture of the bionic silica gel layer is closely attached to the flexible main band 1, and the static friction effectively prevents the device from shifting. The storage module synchronously records the circumference data (such as the contraction stroke of the adjustment belt 5), pressure data and time stamp of the initial adaptation.

[0047] When patients wear the device for daily activities or rehabilitation training, the monitoring unit continuously collects data and transmits it to the controller in real time. The controller then activates different control logics based on the data characteristics to achieve a dynamic linkage where abnormal pressure leads to increased girth and frequent activity leads to decreased girth.

[0048] Circumference increase control when pressure exceeds the limit: When a patient sits for a long time, local blood circulation slows down, causing slight tissue swelling. The pressure sensor detects that the pressure in the corresponding area of ​​the patella exceeds the pressure threshold, and this continues for 3 sampling cycles. The controller immediately determines that the pressure is "excessive". The controller outputs a reverse pulse signal to the drive unit 2, which drives the lead screw 3 to rotate counterclockwise. The nut seat 4 moves away from the drive unit 2, the adjusting band 5 relaxes, and the circumference gradually increases. At the same time, the support bar 6 slowly resets as the circumference increases, and the conical spring relaxes synchronously, gradually reducing the pressure. When the pressure returns to the pressure threshold, the controller sends a stop signal, the drive unit 2 locks, and the storage module records the time, peak value, and control parameters of this pressure abnormality.

[0049] Circumference Reduction Control During Frequent Activity: When a patient performs knee joint rehabilitation training (such as flexion and extension exercises), the angle sensor detects that the change in joint flexion and extension angle exceeds the activity threshold, and the pressure sensor detects that the pressure in the corresponding area of ​​the lateral condyle is lower than the pressure threshold. The controller determines that "frequent activity leads to decreased fit." The controller drives the drive component 2 to rotate forward, the adjustment belt 5 slightly contracts, the circumference decreases, the support bar 6 deforms synchronously with joint flexion, the conical spring compresses, and the pressure rises back to the pressure threshold, ensuring that the device always fits during joint movement. During training, the angle sensor collects data every 0.1 seconds, and the controller dynamically adjusts the circumference according to the change in angle, keeping the pressure stable within the optimal range, avoiding the problems of looseness during activity and excessive tightness when at rest found in traditional devices.

[0050] During device operation, the wireless communication module (Bluetooth 5.0) transmits real-time pressure data, joint range of motion, circumference adjustment records, and power consumption information to the mobile terminal. Patients or medical staff can visually view data curves, such as "24-hour pressure change graph" and "joint range of motion statistics." When clinical evaluation is required, medical staff can send a data export command to the controller. The storage module uploads monitoring data and operation records for a specified time period (e.g., within 7 days) to the terminal via the wireless communication module. The data format supports Excel export, facilitating personalized adjustments to the rehabilitation plan.

[0051] After the patient completes rehabilitation treatment, the controller sends a "maximum circumference" command to the drive unit 2. The drive unit 2 drives the lead screw 3 to reverse to its extreme position, and the adjusting belt 5 fully expands, reaching the maximum circumference. The patient can then easily remove the device from the knee joint. The controller automatically shuts down all functional units, leaving only the power management module in standby mode. The storage module saves the last running data, forming a complete usage record.

[0052] Example 2:

[0053] The difference from Example 1 is that it further includes a physiotherapy unit. The physiotherapy unit adopts a magnetic adsorption detachable structure. The flexible main belt body 1 corresponds to the outer area of the "pin" - shaped support bars 6 of the arc - shaped support unit, and 3 groups of mounting grooves with neodymium - iron - boron magnetic sheets are preset, corresponding to the key physiotherapy areas of the patella and the medial and lateral condyles of the femur respectively. The physiotherapy unit includes a hot compress module and a low - frequency pulse module. Both the hot compress module and the low - frequency pulse module are signal - connected to the controller. When the pressure data is equal to the pressure threshold and the static time of the joint movement data is greater than the time threshold in the controller, the controller controls the start of the hot compress module and the low - frequency pulse module.

[0054] The specific implementation process is as follows: Align the housing of the physiotherapy unit integrated with the hot compress module and the low - frequency pulse module with the mounting groove, and precisely dock the metal contacts of the physiotherapy unit with the conductive terminals in the mounting groove of the main belt body to achieve signal and power connection with the controller.

[0055] After the patient completes the pre - wearing of the device according to the method of Example 1, the girth adjustment unit starts and completes the initial girth adjustment, making the pressure at each point detected by the pressure sensor stable at the pressure threshold. At this time, the controller continuously monitors the joint movement data through the angle sensor to judge whether the joint is in a static state, and at the same time, the timing module starts to accumulate the static time.

[0056] When reaching the preset physiotherapy start time threshold in the controller, when the patient maintains a sitting position for rehabilitation and rest, the angle sensor detects that the joint static time reaches the time threshold, and the pressure sensor continuously feedbacks that the pressure is stable at the pressure threshold, meeting the dual start conditions of pressure matching and static time compliance. The controller immediately outputs a start instruction to the physiotherapy unit, and the storage module synchronously records the trigger condition data (pressure value, static duration) and the time stamp of the physiotherapy start.

[0057] When the controller starts the physiotherapy unit, it adopts a linkage control logic of hot compress pre - heating and pulse follow - up to avoid cold start stimulation: The hot compress module starts first. The controller outputs a regulation signal to the hot compress module, and the hot compress module starts to heat up, and the temperature quickly rises to 38°C and maintains the temperature in the comfortable range of 38 - 42°C. 30 seconds after the hot compress module starts, the controller sends a start signal to the low - frequency pulse module, and the low - frequency pulse module adjusts in real - time to adapt to different pain tolerances.

[0058] During physiotherapy, the monitoring unit continuously collects data, and the controller determines in real time whether the physiotherapy operation conditions are maintained: if the pressure sensor detects that the pressure exceeds the pressure threshold, or the angle sensor detects that the change in joint movement angle is greater than the activity threshold, the controller immediately pauses the low-frequency pulse module and simultaneously lowers the temperature of the heat therapy module to 38°C for heat preservation; when the pressure returns to the pressure threshold and the joint is still again for 30 seconds, the controller resumes the operation of the pulse module to ensure that physiotherapy is only performed under suitable and stable conditions.

[0059] The default runtime of the physiotherapy unit is 20 minutes. When the runtime reaches the set value, the controller will trigger an end command. The controller will then shut down the physiotherapy unit by pressing the pulse button first and then gradually stopping the heat therapy to avoid sudden temperature drops that could irritate the skin.

[0060] Example 3:

[0061] The difference from Embodiment 2 is that the monitoring component also includes a temperature sensor, which is used to monitor the temperature data of the skin during physiotherapy. The temperature sensor is fixedly connected to the inside of the biomimetic silicone layer and is connected to the controller signal.

[0062] It also includes a heat dissipation unit, which includes a cooling fan 8, an air guide shroud 9, and heat dissipation holes. The cooling fan 8 is coaxially fixedly connected to the end of the lead screw 3 away from the drive component 2. An air guide channel 901 is opened on the flexible main belt 1, and the air guide channel 901 is connected to the air outlet of the air guide shroud 9. The air guide shroud 9 is sleeved on the outside of the cooling fan 8. The heat dissipation holes include axial heat dissipation holes 601 opened inside the support bar 6 and ventilation holes opened in the biomimetic silicone layer. When the temperature data is greater than the preset temperature threshold in the controller, the controller starts the drive component 2 to increase the size, and at the same time drives the cooling fan 8. The airflow enters the air guide channel 901 through the air guide shroud 9, and then is discharged through the ventilation holes and axial heat dissipation holes 601.

[0063] The specific implementation process is as follows: After the physiotherapy is started, the temperature sensor continuously collects the skin contact temperature and transmits it to the controller. The controller compares the temperature data with the preset temperature threshold in real time, and the storage module simultaneously records the correspondence between the temperature data and the physiotherapy parameters for easy subsequent traceability. During the physiotherapy operation, the controller activates different control logics based on the real-time data from the temperature sensor. When the temperature reaches the temperature threshold, the temperature sensor feeds the data back to the controller, and the controller immediately outputs a control signal to the heat therapy module to maintain the temperature.

[0064] If a patient's skin temperature exceeds the temperature threshold due to differences in local blood circulation, and the temperature sensor returns excessive data for three consecutive sampling cycles, the controller immediately initiates linkage control: it outputs a reverse pulse signal to the drive unit 2, causing the drive unit 2 to rotate the lead screw 3 counterclockwise, thus expanding the adjustment belt 5 and increasing its circumference, creating a tiny gap between the main belt and the skin; the rotation of the lead screw 3 simultaneously drives the cooling fan 8 to run at high speed, drawing in external cold air through the air guide shroud 9 and into the air guide channel 901 of the flexible main belt 1, then contacting the skin surface through the vents of the biomimetic silicone layer, while the axial heat dissipation holes 601 of the support strip 6 accelerate the discharge of internal hot air, forming a through-flow heat dissipation system that draws in cold air and discharges hot air; the power of the hot compress module is reduced, while the low-frequency pulse module remains in normal operation.

[0065] When the temperature sensor detects that the skin temperature has dropped to the temperature threshold, the controller sends a signal: the drive component 2 stops rotating and the circumference stabilizes at the current state; the cooling fan 8 stops rotating with the lead screw 3, and only the heat therapy module continues to operate; after the temperature stabilizes, the controller restores the power of the heat therapy module to maintain the therapeutic effect and ensure that the temperature is always controlled within a safe range.

[0066] Example 4:

[0067] The difference from Embodiment 3 is that it also includes an early warning unit, which comprises an audible and visual alarm and a vibrator, both of which are connected to the controller via signals. When the pressure exceeds a pressure threshold, the temperature exceeds a temperature threshold, or the joint activity data exceeds an activity threshold, the controller triggers the audible and visual alarm and the vibrator. In this embodiment, the audible and visual alarm consists of an LED indicator and a miniature buzzer, and the vibrator uses a miniature vibration motor.

[0068] The specific implementation process is as follows: During operation, the controller compares the monitoring data with the preset threshold in real time. When any early warning trigger condition is met, the early warning unit is immediately activated, and the corresponding functional unit is linked for control. Specific scenarios are as follows:

[0069] Pressure Excess Warning: When prolonged sitting causes localized swelling in the knee joint, and the pressure sensor detects that the pressure in the corresponding area of ​​the patella exceeds the pressure threshold, the controller determines it as "mild pressure excess" and immediately triggers the warning unit: the LED indicator flashes, the buzzer beeps, and the vibrator vibrates briefly; simultaneously, the controller drives the circumference adjustment unit to increase the circumference, and the pressure gradually decreases to the pressure threshold. When the pressure returns to the optimal range, the controller outputs a "cancel signal" to the warning unit, and the warning immediately stops. The storage module records the trigger time, pressure peak, control measures, and cancellation time of this warning.

[0070] Temperature Over-limit Warning: After the physiotherapy session begins, if the temperature sensor detects that the skin temperature of the medial femoral condyle exceeds the temperature threshold, the controller will determine this as "temperature over-limit" and trigger the warning unit: the LED indicator light will remain constantly on, the buzzer will sound continuously, and the vibrator will vibrate continuously; simultaneously, the heat dissipation unit and the physiotherapy unit will be activated: the drive component 2 will rotate the lead screw 3 to increase its circumference, the cooling fan 8 will operate synchronously to accelerate heat dissipation, and the power of the heat therapy module will decrease. When the temperature drops to the temperature threshold, the warning will be lifted, and only the power adjustment of the heat therapy module will remain to ensure that the physiotherapy continues.

[0071] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
