Description

Technical Field

[0001] This invention relates to the field of rehabilitation aids and nursing technology, specifically to a spinal orthopedic device for correcting structural kyphosis of the spine and its support and adjustment method. Background Technology

[0002] Abnormal spinal posture affects postural function and quality of life, and orthotics are often used for conservative intervention in clinical practice.

[0003] Existing spinal orthoses mostly employ rigid backplates, elastic bands, or fixed support structures to correct posture by restricting trunk movement or applying restraint to localized areas. However, existing orthoses still have certain shortcomings in practical applications. First, the support backplate of traditional orthoses typically uses a one-piece rigid structure with a fixed shape, making it difficult to adapt to the differences in the curvature of different users' backs. This results in insufficient fit between the orthose and the body, affecting wearing comfort and long-term adherence.

[0004] To improve the fit between orthotics and the human back, some existing orthotics incorporate airbag structures, using the inflation and deflation of these airbags to alter the contact pressure between the body and the supporting components. However, this type of structure primarily achieves flexible support through localized pressure adjustment, focusing mainly on the pressure distribution at the contact interface, rather than the overall geometry of the supporting structure itself and the force transmission path. Its active adjustment capability is limited, and it is difficult to achieve coordinated adjustment between different support areas based on changes in structural morphology. Therefore, for application scenarios that require dynamic adjustment of the support posture according to the curvature of the human back and orthopedic needs, existing orthopedic devices still have certain limitations, even with the introduction of airbag structures.

[0005] In addition, the orthopedic force output of existing orthopedic devices mostly relies on passive restraint or fixed support. The support state is difficult to adjust according to changes in human posture and orthopedic needs, resulting in insufficient accuracy and adaptability of the orthopedic effect. Summary of the Invention

[0006] To address the aforementioned deficiencies in the prior art, this invention proposes a biomechanical-based spinal orthopedic device.

[0007] The present invention adopts the following technical solution to solve the technical problem: a biomechanical spinal orthopedic device, wherein a constraint component is connected to a support back plate, the support back plate includes support modules extending along the direction of the spine, a module gap is left between adjacent support modules, and they are connected by flexible hinges; The support backplate is worn and fixed to the back of the human body by the restraint assembly.

[0008] Furthermore, an airbag assembly and an air supply assembly for inflating and deflating the airbag assembly are also provided. The airbag assembly drives the flexible hinge to deform through volume changes during inflation and deflation, thereby adjusting the module gaps and the shape of the supporting backplate.

[0009] Furthermore, the airbag assembly includes airbag units respectively disposed in the gaps between the modules. The airbag units are disposed between a pair of adjacent support modules, are installed and fixed with at least one of the adjacent support modules, and are connected to the air supply assembly.

[0010] Furthermore, the support back plate is provided with Velcro, and the airbag unit is provided with an external mounting part. The mounting part is bonded to the Velcro, so that the airbag unit can be detachably fixed in the module gap.

[0011] Furthermore, each airbag unit is independently connected and controlled to the air supply assembly, or they are connected and controlled in groups.

[0012] Furthermore, the gas supply assembly includes a gas source, a valve, and a pressure sensor; The air source is connected to each of the airbag units independently or in groups through an air path, and the air path is equipped with the valve and the pressure sensor.

[0013] Furthermore, the side of the support module facing the back of the human body has a support surface that matches the curvature of the human back.

[0014] Furthermore, the constraint assembly includes a shoulder constraint assembly and a waist constraint assembly, which are respectively connected to the connecting portions provided at the top and bottom of the support back plate; The shoulder restraint assembly and the waist restraint assembly adopt a flexible structure with adjustable length.

[0015] A method for adjusting the support of a spinal orthopedic device, used to adjust the aforementioned biomechanically based spinal orthopedic device, wherein the upper part of the support backplate of the device is provided with a posture sensor for acquiring the user's spinal posture, or both the upper and lower parts are provided with posture sensors for acquiring the user's spinal posture, and each airbag unit is disposed in the gap between the modules within the orthopedic support area, wherein the orthopedic support area is determined based on biomechanical analysis, and the method includes the following steps: S1, The posture sensor collects information to confirm the user's initial spinal posture; S2, based on the difference between the initial spinal posture and the preset target posture range, adjust the pressure of each airbag unit to make the user's spinal posture approach the target posture range; during the adjustment process, the posture sensor keeps collecting and feeding information until the spinal posture reaches the target posture range, and then each airbag unit independently uses the current pressure as its own orthopedic pressure to maintain pressure. S3, the pressure of each airbag unit is periodically adjusted according to a preset adjustment period T; The adjustment cycle T consists of a first stage and a second stage set sequentially. In the first stage, the airbag unit maintains pressure according to its own orthopedic pressure, and in the second stage, the airbag unit depresses, so that the user can actively maintain a good spinal posture.

[0016] Furthermore, in the third step, the duration of the second phase... The duration is 3–10 minutes, and the first stage lasts for [duration missing]. ,and ; The method also includes a fourth step: as the user's ability to actively maintain good spinal posture improves, the adjustment period T is kept constant or increased, gradually increasing... And shorten or gradually increasing Keep The time spent on the device remains unchanged, so as to increase the time that users actively maintain good spinal posture and minimize the time that the device passively corrects.

[0017] This invention provides a biomechanical-based spinal orthopedic device with the following beneficial effects: 1. This invention employs a modular support structure with multiple support modules connected by flexible hinges. By utilizing an air supply component to inflate, deflate, and maintain the pressure of the airbag component, the relative posture between the support modules is adjusted or maintained. This adjusts the overall geometric shape of the support backplate itself, allowing it to adapt to the curvature of the human back. It also enables active adjustment of the support state of certain areas of the support backplate and coordinated posture adjustment between areas. This effectively solves the problems of insufficient structural adaptability, limited ability to conform to the curvature of the human body, difficulty in adjusting the corrective effect, and insufficient wearing comfort in existing spinal orthopedic devices.

[0018] 2. The airbag assembly in this invention mainly serves as a driving element for adjusting the back support plate, rather than as a flexible filling element between the human body and the supporting structure. The orthopedic device can actively adjust the shape of the back support plate using the airbag assembly to achieve active adjustment of the position and direction of the force exerted by the back support plate on the human body. Compared with the airbag structure in the prior art, which directly serves as a flexible filling element and whose supporting force direction is passively affected by the airbag arrangement position and expansion direction, the orthopedic device of this invention can better adapt to the application scenarios of dynamic adjustment of the support posture for conforming to the curvature of the human back and orthopedic correction.

[0019] 3. Each airbag unit in the airbag assembly of the present invention can be controlled independently or in groups, so that the adjustment of the orthopedic support area has ideal flexibility and adaptability. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] A biomechanically based spinal orthopedic device, such as Figures 1-4 As shown, the structural relationship is as follows: a constraint component 300 is connected to the support back plate 200. The support back plate 200 includes support modules 210 that extend along the spine. A module gap is left between adjacent support modules 210 and they are connected by a flexible hinge 220. The support backplate 200 is worn and fixed to the back of the human body by the constraint component 300, and the flexibility provided by the flexible hinge 220 allows the support backplate 200 to adapt to the curvature of the human back.

[0027] The support module 210 is preferably made of a plate-like structure with a certain rigidity, such as a polymer plate, a composite material plate, or other structural components with support capabilities.

[0028] Preferably, the system also includes an airbag assembly 400 and an air supply assembly 500 for inflating and deflating the airbag assembly 400. The airbag assembly 400 drives the flexible hinge 220 to deform through the volume change of inflation and deflation, so as to adjust the module gap and the shape of the support back plate 200, thereby forming an orthopedic force for the abnormal posture area of ​​the spine.

[0029] Preferably, the airbag assembly 400 includes airbag units 410 respectively disposed in the gap between each module. The airbag unit 410 is disposed between a pair of adjacent support modules 210, is installed and fixed with at least one of the adjacent support modules 210, and is connected to the air supply assembly 500.

[0030] The area on the support backplate 200 with airbag units 410 is an orthopedic support area whose shape can be actively adjusted to support the state. Airbag units 410 should be set or not set in each module gap according to actual needs, such as the biomechanical characteristics of abnormal spinal posture. The inflation, deflation or pressure holding state of each airbag unit, as well as the pressure of the airbag unit, should also be set according to actual needs to improve the matching between the magnitude and position of the orthopedic force and the spinal structure correction.

[0031] In actual setup, the number of support modules 210 can be adjusted according to the length of the human spine, the range of the orthopedic area, and the support requirements; the size, shape, material of the support modules 210, and the structural form of the flexible hinges 220 can all be changed according to actual application requirements. The number and arrangement of airbag units 410, as well as the control method of the air supply components 500, can also be adjusted according to different application scenarios.

[0032] Preferably, the support back plate 200 is provided with Velcro, and the airbag unit 410 is provided with an external mounting part. The mounting part is bonded to the Velcro, so that the airbag unit 410 can be detachably fixed in the module gap.

[0033] Preferably, each airbag unit 410 is independently connected and controlled with the air supply component 500, or they are connected and controlled in groups.

[0034] According to the adjustment requirements of different areas of the support backplate 200, the air supply component 500 controls the airbag units 410 at the corresponding positions to inflate, deflate and maintain pressure independently or in groups, thereby realizing the independent or group adjustment of the shape and support status of different areas of the support backplate 200. When the airbag unit 410 inflates, its volume increases, overcoming the elasticity of the corresponding flexible hinge 220, thus increasing the corresponding module gap. When the airbag unit 410 deflates, its volume decreases, and the corresponding module gap decreases under the elasticity of the flexible hinge 220. When the airbag unit 410 is pressurized, it maintains the shape of the corresponding module gap. By controlling the inflation volume and pressure state of each airbag unit 410, the flexible hinge 220 at the corresponding position can be deformed to different degrees, and the module gap can be formed into different sizes and shapes, so that the support backplate 200 can adjust the support state according to the back curvature of different users and different orthopedic needs.

[0035] Preferably, the gas supply assembly 500 includes a gas source, a valve, and a pressure sensor; The air source is connected to each airbag unit 410 independently or in groups through the air passage, and the air passage is equipped with valves and pressure sensors.

[0036] The valve is used to control the air intake, deflation and pressure holding states of the airbag unit 410; the pressure sensor is used to monitor the internal pressure changes of the airbag assembly 400 to obtain pressure feedback information of the airbag unit 410.

[0037] Preferably, the side of the support module 210 facing the back of the human body has a support surface that matches the curvature of the human back, so as to improve the fit between the support back plate 200 and the human back.

[0038] Preferably, the restraint assembly 300 includes a shoulder restraint assembly 310 and a waist restraint assembly 320, and the shoulder restraint assembly 310 and the waist restraint assembly 320 are respectively connected to the connecting portions provided at the top and bottom of the support back plate 200; The shoulder restraint assembly 310 and the waist restraint assembly 320 are worn on the shoulders and waist of the human body, respectively, to fix the support back plate 200 in a state that fits the back of the human body.

[0039] The shoulder restraint component 310 and the waist restraint component 320 adopt a flexible structure with adjustable length to adapt to the wearing needs of users with different body types and improve the comfort of wearing the orthotic device.

[0040] The shoulder restraint assembly 310 and the waist restraint assembly 320 are preferably made of webbing, elastic band or other flexible connection structure.

[0041] The process of using the above-mentioned biomechanical-based active kyphosis correction device for spinal structural correction includes the following steps: The first step is to conduct a biomechanical analysis based on the user's spinal medical impact to determine the orthopedic support area of ​​the device, and then rationally arrange and install each airbag unit 410 in the gaps between the modules within the orthopedic support area.

[0042] The second step involves the user wearing the orthopedic device through the shoulder restraint component 310 and the waist restraint component 320, so that the support back plate 200 initially fits against the back of the human body.

[0043] The third step is to adjust the spinal orthosis device according to its support adjustment method, specifically as follows: S1, The posture sensor collects information to confirm the user's initial spinal posture; S2, based on the difference between the initial spinal posture and the preset target posture range, adjust the pressure of each airbag unit 410 to make the user's spinal posture approach the target posture range; during the adjustment process, the posture sensor keeps collecting and feeding information until the spinal posture reaches the target posture range, and then each airbag unit 410 independently uses the current pressure as its own orthopedic pressure to maintain pressure. S3, periodically adjust the pressure of each airbag unit 410 according to the preset adjustment cycle T; The adjustment cycle T consists of a first stage and a second stage set sequentially. In the first stage, the airbag unit 410 maintains pressure according to its own orthopedic pressure, and in the second stage, the airbag unit 410 depressurizes, so that the user can actively maintain a good spinal posture.

[0044] S4, as the user's ability to actively maintain good spinal posture improves, while keeping the adjustment period T constant, gradually increases. And shorten This increases the time users spend actively maintaining good spinal posture and reduces the time the device passively corrects.

[0045] The standard parts and conventional components involved in this invention are commercially available, and the circuit connections adopt conventional connection methods in the prior art.
