[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] Combination Figures 1 to 9 As shown, an embodiment of the present invention provides a patella protection and adjustment device, including a brace layer 100 and an airbag layer 200, wherein: the brace layer 100 includes a femoral support plate 110, a tibial support plate 120, a knee extension and flexion rotation hinge 130, an inversion and valgus orthopedic hinge 140 and a plurality of bandages; the airbag layer 200 includes a patella orthopedic airbag 210 and an inflatable bag 220; The femoral support plate 110 is used to fit the femur; the femoral support plate 110 is an important component of the patella protection and adjustment device, which is designed to fit the femur and provide stable support. The main function of the support plate is to disperse and withstand the pressure from the femur to ensure that the knee joint remains stable during exercise. Through the synergistic effect with other components, the femoral support plate 110 can effectively support the knee joint and reduce pain and discomfort caused by joint instability.

[0025] The tibial support plate 120 is used to match the tibia; the tibial support plate 120 is arranged opposite to the femoral support plate 110 and is used to match the tibia. Its main function is to support and fix the tibia to ensure the stability of the knee joint during flexion and extension. The tibial support plate 120 forms a complete support system by connecting with the femoral support plate 110, providing the necessary mechanical support for the knee joint and helping the patient maintain the correct posture and force line during the rehabilitation process.

[0026] The knee flexion and extension rotary hinge 130 is disposed between the femoral support plate 110 and the tibial support plate 120, and is used for the flexion and extension of the brace layer 100; this hinge design allows the knee joint to flex and extend within a natural range of motion, providing flexible motion support. The existence of the rotary hinge can not only help patients to carry out daily activities, but also provide necessary assistance in rehabilitation training, reduce the burden on the knee joint, and promote the rehabilitation process.

[0027] The valgus and valgus orthopedic hinge 140 is arranged between the femoral support plate 110 and the tibial support plate 120, and is used to adjust the valgus and valgus angle of the knee joint; through the preset angle adjustment, the hinge can correct the patient's lower limb force line and help restore normal knee joint function. The design of the valgus and valgus orthopedic hinge 140 is particularly suitable for patients with unilateral shoulder arthritis, and helps to alleviate the pain and discomfort caused by valgus and valgus of the knee joint.

[0028] Multiple sets of bandages connect the femoral support plate 110 and the tibial support plate 120 to fix the brace layer 100; these bandages can be adjusted according to the shape of the patient's legs to provide personalized fit and support. Through the fixation of multiple sets of bandages, the brace layer 100 can remain stable during exercise and prevent displacement, thereby improving the use effect and comfort of the brace.

[0029] The patellar orthopedic airbag 210 is arranged outside the knee joint to apply pressure to the patella; the patellar orthopedic airbag 210 is designed to reduce the burden on the patella and protect the patella from excessive pressure shock through flexible pressure distribution. The use of the patellar orthopedic airbag 210 is particularly suitable for patients with patellar arthritis, which helps to relieve pain and provide additional protection.

[0030] The inflatable bag 220 is connected to the patellar orthopedic bag 210 through a one-way valve 230, and is used to adjust the pressure in the patellar orthopedic bag 210; the patient or medical staff can inflate or deflate the inflatable bag 220 through the one-way valve 230 as needed, thereby adjusting the pressure of the patellar bridge-shaped bag. This design enables the patellar bridge-shaped bag to provide personalized pressure adjustment, meet the needs of different patients, and improve comfort and treatment effects.

[0031] The airbag layer 200 is attached to the brace layer 100 to provide patella protection during knee valgus correction and flexion and extension. The airbag layer 200 can evenly distribute pressure around the knee joint and provide comprehensive support and protection by closely cooperating with the brace layer 100. The airbag layer 200 can not only reduce the force on the patella, but also provide assistance during flexion and extension, helping patients to carry out rehabilitation training and daily activities.

[0032] The working principle of the present invention is as follows: the patella protection and adjustment device realizes the functions of knee valgus correction, patella protection and flexion and extension movement assistance through the cooperation between the brace layer 100 and the airbag layer 200. Specifically, the femoral support plate 110 and the tibial support plate 120 of the brace layer 100 are connected by the extension and flexion knee rotation hinge 130, allowing the knee joint to provide stable support and assistance during flexion and extension movements; the valgus and varus orthopedic hinge 140 is arranged between the femoral support plate 110 and the tibial support plate 120, which can adjust the valgus and varus of the knee joint. Angle, correct lower limb force line; multiple groups of bandages ensure the stability and fit of the brace layer 100 during use; the airbag layer 200 includes a patellar orthopedic airbag 210 and an inflatable bag 220, and the pressure in the airbag is adjusted by a one-way valve 230 to apply appropriate pressure to the patella, thereby achieving patella protection; the patella protection and adjustment device, through the ingenious design of the brace layer 100 and the airbag layer 200, can provide correction and protection while assisting patients to complete daily flexion and extension exercises, thereby achieving a comprehensive solution to multiple clinical needs.

[0033] In this embodiment, the airbag layer 200 also includes a patellar rubber ring 240 and a sleeve assembly 250. The sleeve assembly 250 is used to be mounted on the user's leg; the sleeve assembly 250 is cone-shaped; the patellar rubber ring 240 is arranged in the middle of the sleeve assembly 250 and surrounds the patella area to reduce the force on the patella; wherein, the patellar orthopedic airbag 210 is arranged on the outside of the patellar rubber ring 240 to adjust the pressure of the patellar rubber ring 240.

[0034] It should be noted that the patellar rubber ring 240 provides effective protection for the patella by surrounding the patellar area, reduces the force on the patella, and relieves the pain of patients with patellar arthritis. The setting of the patellar orthopedic airbag 210 can further optimize the protective effect of the patellar rubber ring 240 by adjusting the pressure, ensuring that the patella can be properly supported and protected in different motion states, thereby improving the patient's comfort and treatment effect.

[0035] Combined with the structure of the entire airbag layer 200, the airbag layer 200 of the patella protection and adjustment device is connected to the patellar orthopedic airbag 210 through the inflatable bag 220 and the one-way valve 230. When working, the inflatable bag 220 adjusts the input of gas to increase or decrease the pressure in the patellar orthopedic airbag 210. The patellar orthopedic airbag 210 is located on the outside of the patellar rubber ring 240, and affects the patellar rubber ring 240 by adjusting its own pressure, thereby protecting and supporting the patellar area. The patellar rubber ring 240 surrounds the patellar area, reduces the force on the patella, and provides flexible protection under the action of the airbag pressure to adapt to different motion states and pressure requirements.

[0036] The design of the patella protection and adjustment device provides effective protection and pressure adjustment for the patella through the action of the airbag layer 200. The patellar orthopedic airbag 210 interacts with the patellar rubber ring 240 to flexibly adjust the pressure in the patellar area, reduce the force on the patella, and relieve the discomfort and pain caused by uneven patellar pressure. The presence of the inflatable bag 220 makes the adjustment process more convenient, and the user can manually or electrically adjust the pressure as needed, providing a personalized protection plan. The overall design improves the comfort and safety of the user, and is particularly suitable for patients with patellar arthritis or athletes who need patellar protection, and has a significant effect.

[0037] In this embodiment, it is further explained that the patella rubber ring 240 is in an elliptical ring shape, and the patella orthopedic airbag 210 includes an airbag portion 211 connected to the one-way valve 230, and a main airbag portion 212 integrally arranged with the connecting airbag portion 211; wherein, the main airbag portion 212 is arc-shaped, and the main airbag portion 212 is arranged to fit the outer wall of the patella rubber ring 240.

[0038] As one of the optional solutions of the inflatable bag 220 of this embodiment, the inflatable bag 220 is a manual inflatable bag, and the manual inflatable bag includes: A manual button pump, used to supply air pressure to the patellar orthopedic airbag 210 by manual pressing; A deflation button, used to release the gas in the patellar orthopedic airbag 210 by pressing; The inflation tube is connected to the manual key pump, the deflation button and the patellar orthopedic airbag 210 and is used for transmitting gas.

[0039] It should be noted that the manual inflatable airbag is pumped by the user by pressing the manual button to deliver air to the patellar orthopedic airbag 210 through the inflation tube. Due to the function of the one-way valve 230, the gas can only enter the airbag and will not leak, thereby increasing the pressure in the airbag. When the pressure needs to be reduced, the user can release part of the gas through the deflation button or valve to adjust the pressure of the patellar orthopedic airbag.

[0040] As a second optional solution of the inflatable bag 220 of this embodiment, the inflatable bag 220 is an automatic inflatable bag, which includes: A micro electric pump, used for automatic inflation, to increase the air pressure in the patellar correction airbag 210 electrically; An intelligent control chip, used to control the operation of the micro electric pump and adjust the inflation and deflation processes, wherein the intelligent control chip can automatically adjust the air pressure in the patellar orthopedic airbag 210 according to a preset pressure value; A pressure sensor, used to monitor the pressure in the patellar correction airbag 210 in real time and transmit the monitoring data to the intelligent control chip; A power module, including a battery assembly, is used to provide power to the micro electric pump and the intelligent control chip; The inflation tube connects the micro-electric pump and the patellar orthopedic airbag 210 and is used for transmitting gas.

[0041] The electric inflatable airbag controls the operation of the micro-electric pump through the intelligent control chip, and automatically delivers air to the patellar orthopedic airbag 210 through the inflation tube. The pressure sensor monitors the pressure in the airbag in real time and feeds the data back to the intelligent control chip. According to the preset pressure value, the intelligent control chip adjusts the working state of the micro-electric pump to ensure that the pressure in the airbag remains within the required range. When the pressure needs to be reduced, the intelligent control chip controls the solenoid valve to release gas to adjust the pressure of the patellar orthopedic airbag.

[0042] In this embodiment, it is further explained that the brace layer 100 further includes a bandage buckle group 150, which is provided on the femoral support plate 110 and the tibial support plate 120 for fixing the bandage. The design of the bandage buckle group 150 increases the stability and fixing effect of the brace layer 100. By providing the bandage buckle group 150 on the femoral support plate 110 and the tibial support plate 120, the bandage can more firmly fix the brace layer 100 to prevent displacement or loosening during use, thereby improving the patient's comfort and the use effect of the brace.

[0043] In this embodiment, it is specifically explained that three groups of bandage buckle groups 150 are provided, and the same group of bandage buckle groups 150 is provided with two buckles, which are respectively provided on the femoral support plate 110 and the tibial support plate 120; two groups of bandage buckle groups 150 are strip grooves, and the other group of bandage buckle groups 150 is an arc groove. Such a design provides multiple fixing methods and enhances the adaptability and flexibility of the brace layer 100.

[0044] It should be noted that the bandage buckle group 150 with strip grooves can provide a linear fixation effect, which is suitable for a larger range of adjustments; while the arc-shaped groove can provide a more precise fixation, which is suitable for parts that require fine adjustment. Through the bandage buckle groups 150 of different shapes, the brace layer 100 can better fit the patient's legs and provide personalized support and protection.

[0045] In this embodiment, the femoral support plate 110 includes a first support plate 111 and a second support plate 112. An arc-shaped groove 113 is provided at one end of the first support plate 111, and a protrusion 114 is provided at one end of the second support plate 112 close to the first support plate 111. The side wall of the protrusion 114 is provided with an arc-shaped portion 115 matching the arc-shaped groove 113.

[0046] It should be noted that this design enables the first support plate 111 and the second support plate 112 to fit closely together to form a stable overall structure. The arc-shaped groove 113 and the arc-shaped portion 115 of the protrusion 114 are interlocked, which not only enhances the stability of the femoral support plate 110, but also improves its load-bearing capacity. Through this structural design, the femoral support plate 110 can better adapt to the shape of the patient's legs, provide more reliable support and protection, and further improve the overall performance of the knee brace.

[0047] Specifically, a telescopic plate 116 is provided on the inner wall of the first support plate 111, and the telescopic plate 116 protrudes from the first support plate 111; a connecting plate 117 is provided on the inner wall of the second support plate 112, and a sliding cavity is formed between the connecting plate 117 and the first support plate 111, and the telescopic plate 116 is slidably connected in the sliding cavity.

[0048] Among them, the telescopic plate 116 is provided with a displacement groove 1161 along its length direction, and a plurality of limiting holes 1162 are arranged at intervals along the displacement groove 1161, and the diameter of the limiting hole 1162 is larger than the width of the displacement groove 1161; a locking piece 118 is provided on the second support plate 112, and one end of the locking piece 118 is inserted into the limiting hole 1162 to limit the height of the telescopic plate 116.

[0049] During operation, the telescopic plate 116 can slide freely in the sliding cavity, thereby adjusting the length of the femoral support plate 110 to adapt to the leg lengths of different patients. Through the cooperation of the telescopic plate 116 and the sliding cavity, the brace layer 100 can provide flexible length adjustment, ensuring that the brace can fit the patient's leg closely, providing stable support and a comfortable wearing experience.

[0050] It should be noted that, through this limiting mechanism, the telescopic plate 116 can be accurately adjusted in height within the displacement slot 1161, and the locking member 118 inserted into the limiting hole 1162 can effectively fix the position of the telescopic plate 116 to prevent it from sliding or shifting during use. The design of the limiting hole 1162 makes the adjustment of the telescopic plate 116 more flexible and provides different gear settings.

[0051] It is further explained that a button position 160 is provided on the outer wall of the second support plate 112, and an unlocking button 161 is provided on the button position 160. The unlocking button 161 is connected to the locking member 118 via a connecting column 162. A return spring 163 is sleeved on the connecting column 162, and one end of the return spring 163 abuts against the telescopic plate 116.

[0052] It should be noted that the user can release the locking member 118 by pressing the unlocking button 161, thereby adjusting the position of the telescopic plate 116. The function of the reset spring 163 is to ensure that the unlocking button 161 can automatically reset after being released, thereby maintaining the stability of the locking member 118. Through this unlocking and reset mechanism, the user can conveniently adjust the length of the telescopic plate 116, thereby improving the convenience of use and adjustment flexibility of the knee brace.
