Description

Technical Field

[0001] This invention relates to corrective devices, and more particularly to a corrective device for preventing mild scoliosis in children. Background Technology

[0002] The spine is the pillar of the body, located in the middle of the back, connecting the skull at the top and the tip of the coccyx at the bottom. It participates in the formation of the thoracic cavity, abdominal cavity, and pelvic cavity, protecting the organs in each cavity, providing safety for the spinal cord and spinal nerves, and is also the attachment site for many skeletal muscles, playing a role in supporting body weight and movement. Problems with the physiological curvature of the spine will affect the body's health.

[0003] A search of existing published literature reveals that patent publication number CN111110420A discloses an orthosis for primary school students to prevent scoliosis, relating to the field of orthosis technology. It includes two arc-shaped plates rotatably connected by a rotating shaft. One of the arc-shaped plates has an installation cavity containing a heating plate. A sliding block is slidably connected to the bottom of the installation cavity. The lower sidewalls of the arc-shaped plates are symmetrically equipped with fixing mechanisms, the sides of which abut against the lower sidewalls of the sliding blocks. A second connecting block is installed on the sidewall of one arc-shaped plate, and a first connecting block is installed on the sidewall of the other arc-shaped plate. A limiting groove is formed in the second connecting block, and a limiting block is fixedly connected to the sidewall of the first connecting block. Through the cooperation of the positioning rod, the first connecting block, the second connecting block, the limiting block, the second spring, and the pull rod, the device can be quickly opened and fixed, facilitating the carrying of primary school students. However, this orthosis still has the following drawbacks: Although the corrector allows for quick opening and fixing, making it convenient for elementary school students to wear, children have weaker self-control and are more active, making it difficult for them to wear such devices for extended periods. This results in limited effectiveness and poor compliance. Summary of the Invention

[0004] In order to overcome the shortcomings of children's weak self-control, frequent activities, poor wearing compliance of traditional scoliosis prevention and correction devices, and limited actual correction effect, this invention can provide a mild scoliosis prevention and correction device for children.

[0005] The technical solution is as follows: A mild scoliosis prevention and correction device for children includes a first main correction plate and a second main correction plate. The second main correction plate is located at the bottom of the first main correction plate. A secondary correction plate is located on the outer side of both the first and second main correction plates. Both ends of the secondary correction plates are fixedly connected to telescopic fixing straps. An L-shaped mounting groove is opened at the top of the first main correction plate. A first tension spring is located on the lower left side of the L-shaped mounting groove. A pressing block is connected to the top of the first tension spring. A feedback mechanism is located inside the L-shaped mounting groove. A connecting rope is located at the top of the pressing block. A female buckle is located at the top of the telescopic fixing strap. A male buckle that matches the female buckle is located at the end of the connecting rope away from the pressing block. The pressing block passes through the top of the first main correction plate. A locking mechanism is located between the first and second main correction plates. An adjustment mechanism is located on the second main correction plate.

[0006] Optionally, the feedback mechanism includes a movable plate, a bearing, a connecting rod, an inclined block, a moving plate, a second tension spring, and a contact rod. A bearing is provided on the rear side above the L-shaped mounting groove. A movable plate is rotatably connected to the outer side of the bearing. A torque spring is connected between the bearing and the movable plate. The end of the movable plate near the pressing block is located below the pressing block. A connecting rod is hinged to the outer side of the end of the movable plate away from the pressing block. An inclined block is provided at the bottom of the connecting rod. A moving plate is slidably connected to the lower right side of the L-shaped mounting groove. A second tension spring is provided on the rear side wall of the lower right side of the L-shaped mounting groove. The front end of the second tension spring is connected to the rear of the moving plate. A contact rod is provided at the front end of the moving plate. A through hole is opened at the front end of the first main correction plate, and the contact rod is located in the through hole.

[0007] Optionally, the locking mechanism includes an L-shaped plate, a compression spring, and a circular locking block. A groove is opened on the rear side of the first main correction plate, and several evenly distributed locking slots are opened on the left and right sides of the groove. The second main correction plate is slidably connected in the groove. L-shaped plates are slidably connected to the top left and right sides of the second main correction plate. A compression spring is connected between the two L-shaped plates. A circular locking block is provided at the end of each L-shaped plate near the locking slot, and the circular locking block fits into the locking slot.

[0008] Optionally, the adjustment mechanism includes a knob, a worm, a worm wheel, and a threaded rod. The threaded rod is rotatably connected inside the second main straightening plate, and the worm wheel is threadedly connected to the outside of the threaded rod. The worm is rotatably connected to the front side of the second main straightening plate. The worm and the worm wheel mesh with each other. A knob is provided at the front end of the worm, and the top of the threaded rod is connected to the bottom of the first main straightening plate.

[0009] Optionally, the connecting rope is made of non-elastic nylon braided tape.

[0010] Optionally, there may be multiple female buckles.

[0011] Optionally, it also includes rubber pads, with rubber pads provided at the front ends of both the first and second main correction plates.

[0012] Optionally, the contact rod incorporates a pressure sensor, a microcontroller, and a wireless communication module.

[0013] The beneficial effects of this invention are as follows: 1. This invention features a mechanical linkage mechanism consisting of a telescopic fixing strap, connecting rope, pressing block, movable plate, inclined block, moving plate, and contact rod. When a child exhibits poor posture, it automatically triggers a tactile feedback reminder function, eliminating the need for the child to consciously focus on the posture adjustment process. This is particularly suitable for children with weak self-control. 2. This invention allows manual pressing of the two L-shaped plates to bring them closer together, causing the circular locking block to disengage from its slot. This releases the second main correction plate from the first main correction plate. Then, rotating the knob rotates the worm gear, which in turn drives the worm wheel. The worm wheel then rotates the threaded rod, allowing the first main correction plate to move up and down. This allows the lengths of the first and second main correction plates to be adjusted according to the child's height. 3. The design of the pressure sensor, microcontroller, and wireless communication module in this invention allows the contact rod to move forward and contact the body when a child exhibits poor posture. The pressure sensor detects the pressure change and transmits the signal to the microcontroller for judgment. After confirming an abnormality, the information is sent to parents or doctors via the wireless communication module, enabling remote monitoring and data-driven spinal health management.

Detailed Implementation

[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] A device for preventing and correcting mild scoliosis in children, such as Figures 1-9As shown, it includes a first main straightening plate 1, a second main straightening plate 2, a secondary straightening plate 3, a telescopic fixing belt 4, a pressing block 5, a connecting rope 6, a female buckle 7, a first tension spring 10, a movable plate 11, a shaft seat 12, a connecting rod 13, an inclined block 14, a moving plate 15, a second tension spring 16, and a contact rod 17. The second main straightening plate 2 is located at the bottom of the first main straightening plate 1. The secondary straightening plates 3 are located on the outer sides of both the first main straightening plate 1 and the second main straightening plate 2. The telescopic fixing belts 4 are fixedly connected to both ends of the secondary straightening plates 3. An L-shaped mounting groove is opened at the top of the first main straightening plate 1, and the lower left surface of the L-shaped mounting groove is provided with... The device includes a first tension spring 10, with a pressing block 5 connected to its top. A feedback mechanism is located within an L-shaped mounting groove. A connecting rope 6, made of non-elastic nylon braided webbing, is attached to the top of the pressing block 5. This non-elastic nylon braided webbing maintains its length during wear and use, ensuring accurate transmission of motion to the pressing block 5. Furthermore, this material is soft and gentle on the skin, possesses good abrasion resistance and strength, effectively guaranteeing safety and comfort for children. A female buckle 7 is located at the top of the telescopic fixing strap 4, and the end of the connecting rope 6 furthest from the pressing block 5 engages with the female buckle 7. There are multiple male and female buckles 7. Because there are multiple female buckles 7, the appropriate position of the female buckle 7 can be selected to fix the connecting rope 6 according to the child's specific body shape and correction needs. By selecting the appropriate position of the female buckle 7, it can be ensured that the connecting rope 6 is pulled in the correct position, guaranteeing that the action of the pressing block 5 accurately triggers the feedback mechanism. The pressing block 5 penetrates through the top of the first main correction plate 1. The front end of the first main correction plate 1 has a through hole 9, and the contact rod 17 is located inside the through hole 9. A locking mechanism is provided between the first main correction plate 1 and the second main correction plate 2 to prevent accidental contact by the child. The second main correction plate 2 is equipped with... There is an adjustment mechanism for adjusting the overall length of this corrective device according to the child's height. One of the telescopic fixing straps 4 has a Velcro loop 25 fixedly connected to its inner surface, and the other telescopic fixing strap 4 has a Velcro barbed surface 26 fixedly connected to its outer surface. Adjust the length of the two telescopic fixing straps 4 to fit the child's body shape, put the device on top of the head, so that the first main corrective plate 1 and the second main corrective plate 2 fit against the spine, and the two telescopic fixing straps 4 wrap around the body and meet at the chest or side waist. Press the side with the Velcro barbed surface 26 towards the side with the Velcro loop 25 to stick and fix it to complete the wearing.

[0026] like Figure 3 and Figure 4As shown, the feedback mechanism includes a movable plate 11, a bearing seat 12, a connecting rod 3, a wedge block 14, a moving plate 15, a second tension spring 16, and a contact rod 17. A bearing seat 12 is located on the rear side above the L-shaped mounting groove. The movable plate 11 is rotatably connected to the outer side of the bearing seat 12. A torque spring connects the bearing seat 12 and the movable plate 11. The end of the movable plate 11 near the pressing block 5 is located below the pressing block 5. A connecting rod 13 is hinged to the outer side of the end of the movable plate 11 away from the pressing block 5. A wedge block 14 is located at the bottom of the connecting rod 13. A moving plate 15 is slidably connected to the lower right side of the L-shaped mounting groove. A second tension spring 16 is located on the rear side wall of the lower right side of the L-shaped mounting groove. The front end of the second tension spring 16 is connected to the rear of the moving plate 15. A contact rod 17 is located at the front end of the moving plate 15. 7. The front end of the contact rod 17 is made of rubber. When the contact rod 17 pops forward to remind a child, it will not cause a hard impact or stinging sensation to the body, making the reminder process gentler and more acceptable, especially suitable for children. The contact rod 17 has a built-in pressure sensor, microcontroller and wireless communication module. The pressure sensor is used to detect the change in contact pressure between the contact rod 17 and the child's body. When the child has poor posture, the contact rod 17 extends forward and contacts the body. The pressure sensor senses the pressure change and transmits the signal to the microcontroller. The microcontroller determines whether it is poor posture according to the preset pressure threshold, and then sends the information to the parents or doctor through the wireless communication module to realize remote supervision and achieve scientific and data-driven spinal health management.

[0027] like Figure 7 As shown, the locking mechanism includes an L-shaped plate 18, a compression spring 19, and a circular locking block 20. A sliding groove is opened on the rear side of the first main correction plate 1, and several evenly distributed locking slots are opened on the left and right sides of the sliding groove. The second main correction plate 2 is slidably connected to the sliding groove. The top left and right sides of the second main correction plate 2 are slidably connected to the L-shaped plate 18, and the compression spring 19 is connected between the two L-shaped plates 18. A circular locking block 20 is provided at the end of each L-shaped plate 18 near the locking slot. The circular locking block 20 fits into the locking slot. By manually pressing the two L-shaped plates 18, the two L-shaped plates 18 are brought closer together, which drives the circular locking block 20 to move closer together, so that the circular locking block 20 is disengaged from the locking slot, thereby releasing the fixation of the second main correction plate 2 to the first main correction plate 1. At this time, the compression spring 19 is in a compressed state.

[0028] like Figure 8As shown, the adjustment mechanism includes a knob 21, a worm gear 22, a worm wheel 23, and a threaded rod 24. The threaded rod 24 is rotatably connected inside the second main correction plate 2, and the worm wheel 23 is threadedly connected to the outside of the threaded rod 24. The worm gear 22 is rotatably connected to the front side of the second main correction plate 2. The worm gear 22 and the worm wheel 23 mesh with each other. The knob 21 is located at the front end of the worm gear 22. The top of the threaded rod 24 is connected to the bottom of the first main correction plate 1. After the locking mechanism is released, the knob 21 can be rotated. Rotating the knob 21 drives the worm gear 22 to rotate, which in turn drives the worm wheel 23 to rotate. The worm wheel 23 drives the threaded rod 24 to rotate, thereby realizing the up and down movement of the first main correction plate 1. This allows the length of the first main correction plate 1 and the second main correction plate 2 to be adjusted according to the child's height.

[0029] like Figure 2 As shown, it also includes a rubber pad 8. The front ends of the first main orthotic plate 1 and the second main orthotic plate 2 are both provided with rubber pads 8. The rubber pads 8 have good softness and elasticity, which can buffer the contact pressure between the orthotic plate and the child's body, avoid hard materials directly pressing on the skin, and reduce the discomfort caused by wearing for a long time.

[0030] When this device is worn by a child, the male buckle is snapped onto the female buckle 7 according to the child's body shape, ensuring that the connecting rope 6 does not affect the position of the pressing block 5 after the telescopic fixing strap 4 is fixed. When the child exhibits poor posture such as hunchback or tilting, the lateral bending of the body or deformation of the back muscles will compress the telescopic fixing strap 4, causing it to partially contract. This, in turn, pulls the connecting rope 6 inward and tightens it, causing the pressing block 5 to move upward, thus relieving the pressure of the pressing block 5 on the movable plate 11. The movable plate 11 rotates clockwise under the action of the torque spring, causing the connecting rod 13 to move downward, which in turn pushes the inclined block 14 downward. The inclined block 14 then moves downward. The plate 15 moves forward, and the moving plate 15 pushes the contact rod 17 to extend forward from the through hole 9, pressing against the child's back and generating tactile feedback, thereby reminding the child to correct their sitting posture. After the child corrects their sitting posture, the pressure on their back decreases, the telescopic fixing strap 4 gradually returns to its original state, the tension of the connecting rope 6 is released, and the pressing block 5 resets downward under the action of the first tension spring 10, pressing the moving plate 11 again. The moving plate 11 rotates counterclockwise on the bearing seat 12 and returns to its initial position, driving the connecting rod 13 and the inclined block 14 to move upward. The moving plate 15 slides backward under the pull of the second tension spring 16, driving the contact rod 17 back into the through hole 9. When the length of this corrective device needs to be adjusted according to the child's height, the two L-shaped plates 18 can be manually pressed to bring them closer together, thereby causing the circular locking blocks 20 to move closer together and disengage from the slots. This releases the second main corrective plate 2 from the first main corrective plate 1. Then, the knob 21 is turned, which drives the worm gear 22 to rotate, thereby driving the worm wheel 23 to rotate. The worm wheel 23 drives the threaded rod 24 to rotate, thereby enabling the first main corrective plate 1 to move up and down. This allows the length of the first main corrective plate 1 and the second main corrective plate 2 to be adjusted according to the child's height.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
