Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an adjustable pressure airbag type scoliosis orthosis. Background Technology

[0002] Scoliosis, a three-dimensional spinal deformity that commonly affects adolescents, can lead to trunk asymmetry and abnormal posture if left untreated. It can also compress thoracic organs, impair cardiopulmonary function, and in severe cases, cause lifelong spinal deformities and functional impairments. Currently, in clinical treatment, besides surgical correction, orthotic devices are the core non-surgical treatment for mild to moderate scoliosis. These devices apply directional corrective forces to the spine, guiding it back to its normal physiological curve while inhibiting the progression of scoliosis.

[0003] However, existing scoliosis orthotics still have many technical shortcomings, making it difficult to meet the needs of clinical treatment and patient wearing:

[0004] Poor adaptability of the support structure: Traditional orthotics mostly use an integrated rigid frame, which has a certain support strength, but the frame shape is fixed and cannot dynamically conform to the physiological curves of the spine of different patients. Especially for patients with multi-segment scoliosis or abnormal physiological curvature of the spine, it is easy to cause problems such as excessive local compression or insufficient support. Moreover, the integrated frame cannot be flexibly adjusted according to the changes in the length and shape of the spine during the growth and development of adolescent patients. After 6-12 months of use, it often needs to be re-customized due to decreased adaptability, which results in high treatment costs and affects the continuity of correction.

[0005] Insufficient precision and flexibility in pressure adjustment: Although some existing adjustable pressure orthotics are equipped with airbag components, the airbags are mostly designed as a single unit, which cannot achieve zoned and independent pressure adjustment for the convex side, concave side of scoliosis and different disease segments, resulting in poor targeted application of corrective force; moreover, the airbags are mostly directly glued or fixed to the frame, making disassembly and maintenance inconvenient, and the airbags lack anti-deformation structures, making pressure transmission uneven, leading to local skin pressure sores or weakening of corrective force.

[0006] Fixation and growth adaptation defects: The fixation devices of existing orthotics are mostly adjusted by elastic bands in the shoulders and hips, lacking a special adjustment structure for changes in spinal length. During the growth process, adolescent patients are prone to the frame becoming too long or too short, resulting in the deviation of the corrective force. Some adjustment devices use bolt locking, which is cumbersome to operate and difficult for patients to adjust themselves. They need to frequently go to the hospital, resulting in high medical costs.

[0007] Weak intelligent control and monitoring capabilities: Most existing orthotics rely on doctors to manually adjust the airbag pressure. After adjustment, pressure changes cannot be monitored in real time. When the airbag leaks or the pressure decreases during the patient's activities, it cannot be compensated in time, resulting in unstable corrective effects. A few orthotics with monitoring functions use wired connections, which restricts the patient's activities and cannot achieve synchronous monitoring and independent control of multiple airbag units. Doctors find it difficult to remotely obtain patient wearing data and corrective effects, resulting in low medical management efficiency.

[0008] Therefore, developing a scoliosis orthosis with a highly adaptable support structure, precise zoned pressure adjustment, growth-adaptive adjustment, and intelligent monitoring and control has become a key need to address the shortcomings of existing technologies and improve the correction effect and patient compliance. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides an adjustable-pressure airbag-type scoliosis orthosis. The technical solution is as follows:

[0010] An adjustable pressure airbag scoliosis orthosis includes a main support frame, a fixing and adjusting device, an adjustable pressure airbag device, and an intelligent pressure adjuster. The main support frame conforms to the physiological curve of the human spine and extends to the shoulder and hip at both ends to form a stable support structure.

[0011] The fixing and adjusting device is installed on the main support frame and is used to fix the orthosis to the human body and adapt to different human body sizes;

[0012] The adjustable pressure airbag device can be detachably installed at corresponding positions on the convex and concave sides of the scoliosis on the main support frame.

[0013] Key areas include the corresponding locations on the convex and concave sides of the scoliosis.

[0014] The adjustable pressure airbag device is installed on the main support frame and is used to apply thrust to the convex side of the scoliosis and provide traction to the concave side, guiding the spine to return to the normal physiological curve.

[0015] The intelligent pressure regulator controls the thrust and traction of the adjustable pressure airbag device.

[0016] Optionally, the main support frame includes multiple spinal support joints and multiple connecting balls. The multiple spinal support joints are interconnected by multiple connecting balls, and airbag installation interfaces are reserved at corresponding positions on the convex and concave sides of the scoliosis. The airbag installation interfaces are used for detachable connection of adjustable pressure airbag devices.

[0017] Optionally, the adjustable pressure airbag device includes multiple frame connectors, a thoracic vertebra airbag group, a lumbar vertebra airbag group, and a sacral vertebra airbag group; the frame connectors are detachably hinged to the main support frame, and the thoracic vertebra airbag group, lumbar vertebra airbag group, and sacral vertebra airbag group are detachably installed on the multiple frame connectors respectively.

[0018] When the fixing and adjustment device is fixed on the human body, the thoracic vertebra airbag group corresponds to the thoracic vertebra, the lumbar vertebra airbag group corresponds to the lumbar vertebra, and the sacral vertebra airbag group corresponds to the sacral vertebra.

[0019] Optionally, each airbag assembly of the adjustable pressure airbag device includes at least two independent airbag units. Each independent airbag unit includes an airbag body, a honeycomb inner liner, a micro-inflation pump, an exhaust solenoid valve, and an airbag controller. The honeycomb inner liner is installed inside the airbag body to enhance the airbag's pressure resistance and ensure uniform pressure transmission. The airbag body has an inflation port and an exhaust port. The outlet of the micro-inflation pump is connected to the inflation port of the airbag body through a pipe. The exhaust solenoid valve is installed at the exhaust port. The airbag controller is wirelessly connected to the intelligent pressure regulator through a wireless communication module and controls the execution actions of the micro-inflation pump and the exhaust solenoid valve respectively based on the control commands of the intelligent pressure regulator.

[0020] Optionally, the outer surface of the airbag is uniformly provided with a plurality of raised particles; the raised particles are used to increase the friction between the airbag and the skin to prevent the orthosis from shifting, and at the same time to massage the skin and promote local blood circulation.

[0021] Optionally, the fixing and adjusting device includes a shoulder fixing strap and a hip fixing strap; both the shoulder fixing strap and the hip fixing strap are made of elastic webbing and have Velcro at both ends, which can be adjusted to adapt to different shoulder and hip sizes.

[0022] The spinal length adaptation and adjustment device is installed in the middle of the main support frame and adopts a telescopic structure. The frame length can be adjusted by rotating the adjustment knob.

[0023] Optionally, the fixed adjustment device also includes a pair of spinal length adaptation adjustment components. The pair of spinal length adaptation adjustment components are respectively installed in the main support frame at positions corresponding to the thoracic vertebrae, lumbar vertebrae and sacral vertebrae of the human body. The spinal length adaptation adjustment components include a telescopic rod and a locking member. The base and movable rod of the telescopic rod are detachably installed on the joint of two adjacent spinal support segments. The locking member is used to lock the movable rod of the telescopic rod.

[0024] Optionally, a breathable protective layer is also included, which is installed on the inner side of the main support frame that comes into contact with human skin. The breathable protective layer includes a medical cotton inner layer, a sponge middle layer, and a polyester fiber outer layer.

[0025] Optionally, the intelligent pressure regulator includes multiple wireless pressure sensors, a wireless transceiver module, and an intelligent control terminal. The multiple wireless pressure sensors monitor the pressure values ​​of multiple independent airbag units respectively, and are wirelessly connected to the intelligent control terminal through the wireless transceiver module. The intelligent control terminal wirelessly interacts with the airbag controller to exchange airbag control commands through the wireless transceiver module.

[0026] In summary, the present invention has at least one of the following beneficial technical effects:

[0027] This invention provides an adjustable pressure airbag-type scoliosis orthosis. The main support frame adopts a combination structure of multi-segment spinal support joints and connecting ball joints. The multi-segment joints can rotate at multiple angles through the connecting ball joints, which can dynamically adapt to the physiological curves of the spine and the scoliosis morphology of different patients, avoiding local compression. In addition, the frame is provided with a detachable airbag installation interface, which facilitates the installation, disassembly and maintenance of the adjustable pressure airbag device, and adapts to the correction needs of different disease segments.

[0028] The adjustable pressure airbag device is divided into three independent airbag groups according to the thoracic, lumbar, and sacral vertebrae. Each group contains at least two independent airbag units corresponding to the convex and concave sides of the scoliosis, which can realize zoned positioning and independent pressure adjustment. It can apply directional thrust and traction force to different segments of scoliosis, and the corrective force is highly targeted. The airbag unit has a built-in honeycomb liner, which effectively enhances the pressure resistance, prevents the airbag from deforming under pressure, and ensures uniform pressure transmission. The raised particles on the surface of the airbag not only increase the friction with the skin and prevent the orthosis from shifting, but also massage the local skin, promote blood circulation, and reduce pressure sores and muscle fatigue.

[0029] The spinal length adaptation adjustment component of the fixed adjustment device, through the combination of telescopic rod and locking device, can be adjusted in segments according to the changes in spinal length of adolescent patients, without the need to replace the entire frame, thus extending the service life of the orthosis and reducing treatment costs; the shoulder and hip fixation straps adopt a Velcro design, which can be adjusted by the patient himself, making it easy to operate.

[0030] The intelligent pressure regulator monitors the pressure of each independent airbag unit in real time using wireless pressure sensors. Combined with a wireless transceiver module and an intelligent control terminal, it achieves wireless communication, automatically compensating for pressure attenuation and ensuring stable corrective force. Doctors can remotely obtain data such as patient wearing time and airbag pressure changes through the intelligent control terminal, and remotely adjust pressure parameters, reducing the number of times patients need to visit the hospital and improving medical management efficiency.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] This invention discloses an adjustable pressure airbag type scoliosis orthosis.

[0037] Reference Figure 1 - Figure 3 Example 1: An adjustable pressure airbag scoliosis orthosis includes a main support frame 1, a fixing and adjusting device, an adjustable pressure airbag device and an intelligent pressure adjuster 4. The main support frame 1 conforms to the physiological curve of the human spine and extends to the shoulder and hip at both ends to form a stable support structure.

[0038] The fixing and adjusting device is installed on the main support frame 1 to fix the orthosis to the human body and adapt to different human body sizes;

[0039] The adjustable pressure airbag device can be detachably installed at corresponding positions on the convex and concave sides of the scoliosis on the main support frame 1.

[0040] Key areas include the corresponding locations on the convex and concave sides of the scoliosis.

[0041] The adjustable pressure airbag device is installed on the main support frame 1 and is used to apply a pushing force to the convex side of the scoliosis and provide traction force to the concave side, guiding the spine to recover to the normal physiological curve.

[0042] The intelligent pressure regulator 4 controls the thrust and traction of the adjustable pressure airbag device.

[0043] By adopting the above technical solution, the main support frame 1 serves as the basic support structure of the orthosis. Its shape conforms to the physiological curve of the human spine and extends to the shoulders and hips at both ends. It can form a stable support system covering the key stress areas of the spine. While providing an installation carrier for the fixed adjustment device and the adjustable pressure airbag device, it avoids the failure of the transmission of corrective force due to the displacement of the support structure, and ensures that the subsequent functional components can accurately act on the target parts of the spine.

[0044] The fixing and adjusting device is installed on the main support frame. On the one hand, it fixes the orthosis to the body through its own structure, preventing the orthosis from shifting during daily activities and ensuring that the adjustable pressure airbag device always corresponds to the convex and concave sides of the scoliosis. On the other hand, it can be adjusted according to the shoulder width, hip size and overall length of the spine of different patients, so that the orthosis fits the body well and avoids local pressure or insufficient corrective force due to size mismatch, laying the foundation for the effective application of subsequent corrective force.

[0045] The adjustable pressure airbag device can be detachably installed on the main support frame at the corresponding convex and concave sides of the scoliosis. Its core function is to apply a directional force to the spine through its own pressure changes: for the convex side of the scoliosis, the airbag device generates thrust when it inflates, which acts directly on the convex side of the spine, forming a corrective force in the direction of the concave side; for the concave side of the scoliosis, the airbag device provides traction force to the concave side of the spine through reasonable pressure control, reducing the tension of the soft tissues on the concave side, creating space for the spine to recover to the normal physiological curve. The two work together to guide the spine to gradually get out of the scoliosis state and tend towards the normal physiological curvature.

[0046] The intelligent pressure regulator 4, acting as the core of the corrective force control, dynamically adjusts the pressure of the adjustable airbag device to achieve precise management of thrust and traction: when increased thrust on the convex side is needed, the intelligent pressure regulator controls the airbag device to inflate, increasing the internal pressure to enhance thrust; when adjusting the concave side traction or reducing the convex side thrust is needed, the intelligent pressure regulator controls the airbag device to deflate, reducing the internal pressure to match the corrective needs. This real-time control of airbag pressure ensures that the corrective force applied by the adjustable airbag device always meets the patient's scoliosis correction needs, preventing excessive force from causing skin damage or insufficient force from affecting the corrective effect, thus maintaining the stability and safety of the correction process.

[0047] The main support frame ensures structural stability, the fixed adjustment device ensures precise positioning, the adjustable pressure airbag device provides corrective force, and the intelligent pressure regulator controls the magnitude of the corrective force. The four elements work together to achieve directional and controllable correction of scoliosis, guiding the spine to gradually return to its normal physiological curve.

[0048] Example 2: The main support frame 1 includes multiple spinal support joints 11 and multiple connecting balls 12. The multiple spinal support joints 11 are interconnected by multiple connecting balls 12, and airbag installation interfaces are reserved at corresponding positions on the convex and concave sides of the scoliosis. The airbag installation interfaces are used for detachable connection of adjustable pressure airbag devices.

[0049] Example 3: The adjustable pressure airbag device includes multiple frame connectors 30, a thoracic vertebra airbag group 31, a lumbar vertebra airbag group 32, and a sacral vertebra airbag group 33; the frame connectors 30 are detachably hinged to the main support frame 1, and the thoracic vertebra airbag group 31, the lumbar vertebra airbag group 32, and the sacral vertebra airbag group 33 are detachably mounted on the multiple frame connectors 30 respectively;

[0050] When the fixing and adjustment device is fixed on the human body, the thoracic vertebra airbag group 31 corresponds to the thoracic vertebra, the lumbar vertebra airbag group 32 corresponds to the lumbar vertebra, and the sacral vertebra airbag group 33 corresponds to the sacral vertebra.

[0051] By adopting the above technical solution, the multi-segment spinal support joints serve as the core load-bearing units of the main support frame, interconnected through multiple connecting ball joints. These connecting ball joints possess multi-angle rotation characteristics, allowing adjacent spinal support joints to move flexibly in different directions. This transforms the overall frame from a fixed, rigid structure into one that dynamically adjusts to the individual spinal curvature of each patient, such as the degree of thoracic kyphosis and the angle of lumbar lordosis, conforming to the patient's unique spinal shape. This multi-segment connection design overcomes the limitations of traditional integrated frames that cannot adapt to diverse spinal curves, avoiding localized support gaps or excessive compression caused by mismatch between the frame shape and spinal curves. It ensures that the frame evenly covers key areas of the spine, providing a stable and fitting installation foundation for subsequent fixation and adjustment devices and adjustable pressure airbag devices. Simultaneously, the airbag installation interfaces pre-reserved at corresponding positions on the convex and concave sides of the scoliosis directly provide precise assembly positioning for the adjustable pressure airbag device. The detachable interface design allows the adjustable pressure airbag device to be flexibly installed or removed according to the patient's specific scoliosis location, such as the convex side of the thoracic spine or the concave side of the lumbar spine. The airbag position can be adjusted without replacing the entire frame, adapting to the scoliosis correction needs of different segments. In addition, the detachable connection method also facilitates the daily maintenance and replacement of the airbag device. When a single airbag malfunctions, only the corresponding airbag needs to be removed for repair, without affecting the overall use of the frame. At the same time, it ensures that the airbag is accurately aligned with the convex and concave sides of the scoliosis after each installation, providing positional assurance for subsequent targeted force application.

[0052] Overall, the combination of multi-segment spinal support joints and connecting ball joints solves the problem of poor adaptability of traditional frames, allowing the support structure to conform to the individual spinal shape; the reserved airbag installation interface enables precise docking with the adjustable pressure airbag device. The two work together to give the main support frame both stable support capabilities and lay the foundation for the precise action of subsequent correction components.

[0053] Multiple frame connectors serve as the connection medium between the adjustable-pressure airbag device and the main support frame, with one end connected to the main support frame via a detachable hinge. The hinged structure allows the frame connectors to rotate at multiple angles around the connection point. The tilt angle of the connectors can be adjusted according to the patient's trunk contour and the physiological curvature of the spine, thereby ensuring that the subsequently installed airbag assembly conforms to the body surface. This avoids gaps between the airbag and the skin caused by a fixed connector angle, ensuring that the inflated airbag directly acts on the target spinal region. Simultaneously, the detachable design allows for flexible addition or removal of frame connectors according to the needs of different scoliosis segments. If the patient only has thoracic scoliosis, only the frame connectors connecting the thoracic airbag assembly can be installed at the corresponding positions, reducing unnecessary constraints on the body.

[0054] The zonal design of the thoracic, lumbar, and sacral airbag groups addresses the physiological characteristics and scoliosis correction needs of different segments of the human spine (thoracic, lumbar, and sacral), achieving "segmented force application." Once the orthosis is fixed to the body by the fixation and adjustment device, the three airbag groups precisely correspond to their respective spinal segments, avoiding the problems of traditional one-piece airbags that cannot distinguish segments and have dispersed corrective force. For example, if a patient has right thoracic scoliosis and left lumbar scoliosis, the thoracic airbag group can apply thrust to the right convex side and traction to the left concave side, while the lumbar airbag group applies thrust to the left convex side and traction to the right concave side. The corrective forces of the two segments do not interfere with each other, achieving targeted correction.

[0055] Furthermore, each airbag assembly is detachably mounted on the frame connector, which not only facilitates the selection of the required airbag assembly based on the patient's scoliosis segment (e.g., a lumbar airbag assembly can be installed separately for lumbar scoliosis only), but also allows for individual removal and replacement of airbag assemblies when they age or break, reducing maintenance costs. Simultaneously, the detachable installation method also allows for adjustment of the airbag assembly's installation position as the correction progresses. For example, if the point of application of the corrective force needs to be adjusted as the scoliosis angle improves, the airbag assembly can be removed and reinstalled on a more suitable frame connector, ensuring that the corrective force is always precisely applied to the target area.

[0056] Example 4: Each airbag assembly of the adjustable pressure airbag device includes at least two independent airbag units. Each independent airbag unit includes an airbag body 34, a honeycomb inner liner 35, a miniature inflation pump 36, an exhaust solenoid valve 37, and an airbag controller 38. The honeycomb inner liner 35 is installed inside the airbag body 34 to enhance the airbag's pressure resistance and ensure uniform pressure transmission. The airbag body 34 has an inflation port and an exhaust port. The outlet of the miniature inflation pump 36 is connected to the inflation port of the airbag body 34 through a pipe. The exhaust solenoid valve 37 is installed at the exhaust port. The airbag controller 38 is wirelessly connected to the intelligent pressure regulator 4 through a wireless communication module. Based on the control commands of the intelligent pressure regulator 4, it controls the execution actions of the miniature inflation pump 36 and the exhaust solenoid valve 37 respectively.

[0057] Example 5: The outer surface of the airbag body 34 is uniformly provided with a plurality of raised particles; the raised particles are used to increase the friction between the airbag and the skin to prevent the orthodontic device from shifting, and at the same time to massage the skin and promote local blood circulation.

[0058] By adopting the above technical solution, each airbag group of the adjustable pressure airbag device is equipped with at least two independent airbag units. The core is to achieve precise pressure control for different parts of scoliosis through modular structure and component collaboration.

[0059] The honeycomb liner in the independent airbag unit is installed inside the airbag body. Its honeycomb structure can disperse the pressure on the airbag body, preventing the airbag from deforming due to excessive local stress during inflation and pressurization. At the same time, it allows the internal pressure of the airbag body to be evenly transmitted to the contact area of ​​the spine, preventing local pressure concentration from causing skin discomfort or deviation of corrective force, and laying a structural foundation for subsequent precise force application.

[0060] The airbag has an inflation port and an exhaust port, which serve as channels for pressure input and release, respectively. The outlet of the miniature air pump is connected to the inflation port via a pipe. When it is necessary to increase the pressure of the airbag to enhance the corrective force, the miniature air pump can deliver gas into the airbag. The exhaust solenoid valve is installed at the exhaust port. When it is necessary to reduce the pressure or adjust the magnitude of the corrective force, the exhaust solenoid valve opens to release excess gas inside the airbag. Through bidirectional adjustment of "inflation-exhaust," flexible changes in the airbag pressure can be achieved.

[0061] The airbag controller connects to the intelligent pressure regulator via a wireless communication module, enabling it to receive control commands from the regulator in real time. When the intelligent pressure regulator determines that a specific airbag unit requires increased pressure based on scoliosis correction needs, it sends an inflation command to the corresponding airbag controller. The airbag controller then activates a miniature inflation pump to inflate the airbag. When pressure needs to be reduced, the intelligent pressure regulator sends an deflation command, and the airbag controller controls the deflation solenoid valve to open and release air. Each individual airbag unit can independently respond to the intelligent pressure regulator's commands, achieving differentiated pressure adjustment within different airbag groups. This allows the corrective force to precisely match the needs of the convex and concave sides of the scoliosis, as well as different segments, improving the targeted nature of the correction.

[0062] The raised particles evenly distributed on the outer surface of the airbag achieve a dual function of "fixation and comfort" through physical structural design, which helps to improve the stability of correction and the wearing experience.

[0063] From the perspective of preventing displacement, the raised particles increase the contact friction between the airbag and the human skin. When the patient engages in daily activities (such as standing, walking, and changing sitting posture), the friction between the airbag and the skin can resist the tendency of the orthosis to shift due to body movement, ensuring that the airbag always corresponds to the target area of ​​scoliosis, avoiding deviation of the corrective force from the preset direction due to orthosis displacement, and maintaining the stability of the corrective effect.

[0064] From the perspective of promoting blood circulation, the raised particles will make gentle contact and pressure on the skin during the patient's slight body movements while wearing the orthosis. This pressure can stimulate the blood vessels under the local skin, accelerate blood flow, relieve the problem of poor local blood circulation caused by wearing the orthosis for a long time, reduce discomfort such as skin stuffiness and muscle fatigue, and improve the patient's tolerance for long-term wear.

[0065] Example 6: The fixing and adjusting device includes a shoulder fixing strap 21 and a hip fixing strap 22; both the shoulder fixing strap 21 and the hip fixing strap 22 are made of elastic webbing and have Velcro at both ends, which can be adjusted to adapt to different shoulder and hip sizes.

[0066] The spinal length adaptation and adjustment device is installed in the middle of the main support frame 1. It adopts a telescopic structure and the frame length can be adjusted by rotating the adjustment knob.

[0067] Example 7: The fixed adjustment device further includes a pair of spinal length adaptation adjustment components 23. The pair of spinal length adaptation adjustment components 23 are respectively installed in the main support frame 1 at positions corresponding to the thoracic vertebrae, lumbar vertebrae and sacral vertebrae of the human body. The spinal length adaptation adjustment component 23 includes a telescopic rod 231 and a locking member 232. The base and movable rod of the telescopic rod 231 are respectively detachably installed on the support joints 11 of two adjacent vertebrae. The locking member 232 is used to lock the movable rod of the telescopic rod 231.

[0068] By adopting the above technical solution, the fixation and adjustment device achieves human fixation and size adaptation of the orthosis through the coordination of the shoulder and hip fixation straps and the spine length adaptation adjustment device.

[0069] The shoulder and hip fixation straps are made of elastic webbing, which can adapt to the different contours of the shoulders and hips of different people. The Velcro at both ends can flexibly adjust the tightness of the fixation straps, ensuring that the orthosis will not loosen or shift when fixed to the body, while avoiding excessive tightness that may cause local pressure, thus adapting to the shoulder and hip sizes of different users.

[0070] The spinal length adaptation adjustment device is installed in the middle of the main support frame. The telescopic structure can change the overall length of the frame. By rotating the adjustment knob, the telescopic range can be precisely controlled so that the frame length matches the overall spinal length of different users. This ensures that the main support frame always conforms to the physiological curve of the spine, providing a foundation for the precise action of subsequent correction components.

[0071] The newly added spinal length adaptation adjustment component of the fixed adjustment device can achieve length adaptation of different segments of the spine through segmental adjustment.

[0072] A pair of adjustment components are installed on the main support frame at the positions corresponding to the thoracic-lumbar and lumbar-sacral vertebrae, respectively, to adjust the length requirements of different spinal segments. The base of the telescopic rod connects to the adjacent spinal support joints of the movable rod. Adjusting the length of the movable rod extending or retracting from the base changes the spacing between adjacent joints, thus adapting to the length changes of the corresponding spinal segments. The locking device locks the movable rod after the telescopic rod is adjusted to the correct position, preventing the telescopic rod from loosening during use and causing the segmental spacing to shift. This ensures stable support of the frame for each spinal segment, especially adapting to the differentiated length changes of different segments during the spinal growth of adolescents.

[0073] Example 8 also includes a breathable protective layer, which is installed on the inner side of the main support frame 1 that is in contact with human skin. The breathable protective layer includes a medical cotton inner layer, a sponge middle layer and a polyester fiber outer layer.

[0074] By adopting the above technical solution, the breathable protective layer is installed on the inner side of the main support frame that comes into contact with the human skin. Through the synergistic effect of the three differentiated materials, the support and correction functions of the orthosis are guaranteed while the wearing comfort and durability are improved.

[0075] The medical cotton inner layer comes into direct contact with the skin. Its material has good moisture absorption and softness, which can quickly absorb the sweat produced on the skin surface due to prolonged wear, keeping the skin surface dry and avoiding the stickiness, allergies or friction damage caused by sweat accumulation. At the same time, its softness can reduce friction and irritation between the protective layer and the skin, improving skin contact comfort.

[0076] The foam middle layer is located between the medical cotton inner layer and the polyester fiber outer layer. Its porous structure provides excellent elasticity and cushioning performance. When the main support frame or adjustable airbag device exerts pressure on the human body, the foam middle layer can disperse the local pressure through its own deformation, avoiding concentrated pressure on the skin from the frame or airbag, relieving local muscle soreness and skin discomfort caused by prolonged wear, while maintaining the overall stability of the protective layer.

[0077] The outer layer of polyester fiber faces the main support frame. This material is waterproof, stain-resistant, and abrasion-resistant. On the one hand, it can prevent dust, stains, or trace amounts of moisture from the surface of the main support frame from penetrating into the inner layer, protecting the cleanliness of the medical cotton inner layer and the sponge middle layer, and preventing contamination from affecting hygiene. On the other hand, it can resist the frictional wear of the frame on the protective layer, extending the overall service life of the breathable protective layer.

[0078] Example 9: The intelligent pressure regulator 4 includes multiple wireless pressure sensors 41, a wireless transceiver module 42, and an intelligent control terminal 43. The multiple wireless pressure sensors 41 monitor the pressure values ​​of multiple independent airbag units and are wirelessly connected to the intelligent control terminal 43 through the wireless transceiver module 42. The intelligent control terminal 43 wirelessly interacts with the airbag controller 38 to exchange airbag control commands through the wireless transceiver module 42.

[0079] By adopting the above technical solution, the intelligent pressure regulator achieves real-time monitoring and precise control of the pressure of independent airbag units through the wireless collaboration of various components.

[0080] Multiple wireless pressure sensors correspond to multiple independent airbag units, collecting pressure values ​​from each airbag unit in real time to provide a data basis for pressure regulation. The wireless transceiver module acts as a data transmission hub, wirelessly transmitting the pressure data collected by each wireless pressure sensor to the intelligent control terminal, while simultaneously receiving airbag control commands generated by the intelligent control terminal.

[0081] After receiving the pressure data, the intelligent control terminal determines whether the current pressure matches the scoliosis correction requirements. If the pressure deviates from the preset range, it generates a corresponding inflation or deflation control command. This command is then transmitted again to the airbag controller of each independent airbag unit via a wireless transceiver module. The airbag controller adjusts the action of the miniature inflation pump or deflation solenoid valve according to the command, thereby adjusting the airbag unit pressure.

[0082] The entire process enables real-time data and command interaction via wireless communication, eliminating the need for wired connections. This avoids restricting patient movement and dynamically ensures that the pressure of each airbag unit meets the correction requirements, maintaining the accuracy and stability of the correction force.

[0083] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
