Description

Technical Field

[0001] This invention relates to the field of biofeedback correction technology, and in particular to a three-dimensional spiral biofeedback correction chair. Background Technology

[0002] Idiopathic scoliosis is a three-dimensional deformity that affects 5% of adolescents, with girls being the most commonly affected. The cause of this condition is still unclear. Effective correction must involve the three-dimensional structure of the spine and vertebral rotation, including lateral curvature in the frontal plane, sagittal deformity, and vertebral rotation in the transverse plane. The three-dimensional spiral biofeedback corrective chair is an intelligent rehabilitation device that integrates biomechanical design, spiral support structure and biofeedback technology. It is mainly used for spinal posture correction and sedentary health management. To this end, patent CN112690566B discloses a posture correction chair for students. The technical problem of this invention is to provide a posture correction chair for students with a significant effect on posture correction, a long duration of effect, and scientific and safe use. The technical implementation of this invention is as follows: A posture correction chair for students includes: a base frame and a clamping mechanism, with the clamping mechanism located on the right side of the base frame; and a pushing mechanism, with the pushing mechanism located on the side of the clamping mechanism. Through the cooperation of the clamping mechanism and the pressing mechanism, people's sitting posture can be adjusted, preventing people from hunching over while sitting in the chair. The existing technical solutions mentioned above have the following drawbacks: Although the clamping and pressing mechanisms can adjust people's sitting posture and prevent them from hunching over, and the pushing and pressing mechanisms can adjust the overall upper body posture and better correct people's sitting posture, the current mainstream three-dimensional spiral biofeedback orthodontic chairs, despite achieving technological breakthroughs in three-dimensional support and biofeedback monitoring, still rely on manual operation in the adjustment of the correction position. This results in significant efficiency and experience deficiencies in practical applications. The position adjustment of existing orthodontic chairs lacks a standardized automatic adaptation mechanism and relies entirely on the clinical experience of staff. Differences in the operating habits of different staff members lead to inconsistent correction positions and intensities for the same user in different uses, disrupting the continuity of biofeedback correction and affecting long-term correction effects.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0018] Please see Figures 1-8 The present invention provides a three-dimensional spiral biofeedback correction chair, including a correction structure; The structure is coaxially mounted at the front center of the correction structure. Correction structure: The correction structure includes a base 11, a fixing frame 12, an adjusting rod 15, and a seat 16; The fixing frame 12 is fixedly connected to both sides and the rear of the base 11, the adjusting rod 15 is fixedly connected to the top center of the base 11, and the seat 16 is fixedly connected to the top of the adjusting rod 15. The correction structure also includes an adjustment frame 13, a controller 14, and an auxiliary plate 17; The adjusting frame 13 is rotatably connected to the front end of the fixed frame 12, the controller 14 is rotatably connected to one end of the adjusting frame 13, and the auxiliary plate 17 is slidably connected to the inner top wall of the base 11. The fixed frame 12 is used to provide installation space for the slide rail 31. The controller 14 reads the conditioned pressure signal, compares it with the preset threshold logic, drives the threaded rod 36 to rotate, and outputs control commands. The adjusting frame 13 is used to adjust the usage position of the controller 14. The adjusting rod 15 is used to adjust the height of the seat 16. The seat 16 is used to provide space for the staff to sit. The structure includes a slot 21, a cushion 22, a sleeve 23, and a spring rod 24. The slot 21 is opened inside the seat 16, the spring rod 24 is fixedly connected to the inside of the slot 21, the sleeve 23 is slidably connected to the top of the spring rod 24, and the seat cushion 22 is fixedly connected to the top of the sleeve 23. The structure also includes a first pressure sensor 25 and a signal conditioning circuit 26; The first pressure sensor 25 is fixedly connected to the bottom of the seat 16, and the signal conditioning circuit 26 is fixedly connected to one end of the first pressure sensor 25. The signal conditioning circuit 26 amplifies, filters, and reduces the noise of the weak signal output by the first pressure sensor 25. The radii of the slot 21 and the cushion 22 are the same, and the sleeve 23 and the spring rod 24 are set on the same central axis. With the auxiliary cooperation between the slot 21 and the cushion 22, when the patient sits on the seat 16, the patient's buttocks can be squeezed against the cushion 22, so that the sleeve 23 slides down along the trajectory of the spring rod 24 and squeezes the first pressure sensor 25. Working principle: When the patient sits above seat 16; First, the patient can come into contact with the cushion 22 and squeeze the cushion 22, thereby causing the sleeve 23 to slide down along the trajectory of the spring rod 24; Next, when the sleeve 23 slides down to the preset position, the sleeve 23 can squeeze the first pressure sensor 25. After the first pressure sensor 25 senses the external pressure, it converts the physical quantity of pressure into a weak electrical signal. The signal conditioning circuit 26 then amplifies the weak signal output by the first pressure sensor 25. After the controller 14 reads the conditioned pressure signal, it starts multiple sets of threaded rods 36 to rotate. This step involves automatically activating the corrective chair while the patient is seated at position 16 waiting for correction, freeing up the staff's hands and reducing their workload.

[0019] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, also includes an auxiliary structure; The auxiliary structure includes a slide rail 31, a mounting plate 32, an electric telescopic rod 33, and a screw block 34; The slide rail 31 is fixedly connected to both sides of the inner wall of the fixed frame 12, the mounting plate 32 is slidably connected to the inner side of the fixed frame 12, the electric telescopic rod 33 is fixedly connected to the rear of the mounting plate 32, and the screw block 34 is fixedly connected to both sides of the mounting plate 32.

[0020] The auxiliary structure also includes a correction plate 35 and two sets of threaded rods 36; The correction plate 35 is fixedly connected to the connecting end of the electric telescopic rod 33, and the two sets of threaded rods 36 are respectively rotatably connected to the upper and lower ends of the slide rail 31; The slide rail 31 is used to provide space for the rotation of the threaded rod 36. The slide rail 31 is divided into two parts from the middle. There are two sets of threaded rods 36. The two sets of threaded rods 36 are rotatably connected to the upper and lower parts of the slide rail 31 respectively. The threads on the outside of the two sets of 36 are facing opposite directions. The screw block 34 and the threaded rod 36 are threadedly connected. The screw block 34 is slidably connected to the inside of the slide rail 31. With the auxiliary cooperation between the slide rail 31 and the mounting plate 32, when the two sets of threaded rods 36 rotate at the upper and lower ends of the slide rail 31 respectively, the screw block 34 can slide along the threaded trajectory outside the threaded rod 36 inside the slide rail 31. Working principle: When the controller 14 reads the conditioned pressure signal, it starts multiple sets of threaded rods 36 to rotate; First, the two sets of threaded rods 36 can be rotated at the upper and lower ends of the slide rail 31 respectively, so that the screw block 34 slides along the threaded trajectory outside the threaded rod 36 inside the slide rail 31. Next, the mounting plate 32, which is fixedly connected to the screw blocks 34 on both sides, can slide inside the slide rail 31 and slide to a suitable position. The system set inside the controller 14 can control the electric telescopic rod 33 to work, so that the electric telescopic rod 33 drives the correction plate 35 fixedly connected at one end to slide forward vertically and make the correction plate 35 fit with the patient's correction area. This step can automatically correct the patient's condition according to a predetermined program, thereby improving the accuracy of the correction and making it easier for staff to perform the correction work.

[0021] Please see Figure 5-7 As shown, this embodiment, based on the above embodiment, also includes an inflatable structure; The inflation structure includes a miniature air pump 301, a second pressure sensor 302, an air tube 303, and an air bag 304; The miniature air pump 301 is fixedly connected to one side of the mounting plate 32, the second pressure sensor 302 is fixedly connected to one end of the miniature air pump 301, the air tube 303 is fixedly connected to one side of the miniature air pump 301, and the airbag 304 is fixedly connected to the middle of the front end of the correction plate 35. After the controller 14 presets the pressure threshold, the second pressure sensor 302 provides real-time feedback on the pressure inside the airbag 304. When the pressure is lower than the threshold, the controller 14 starts the micro air pump 301 to inflate the airbag. After the threshold is reached, the micro air pump 301 automatically stops pumping to avoid long-term pressure on the patient's local skin. With the auxiliary cooperation between the micro air pump 301 and the second pressure sensor 302, when the airbag 304 is applied to and squeezed on the patient's part to be corrected, the micro air pump 301 can inflate the inside of the airbag 304 through the air tube 303. Working principle: When the airbag 304 is applied to and squeezed against the area to be corrected on the patient; First, the airbag 304 can fit into the patient's area to be corrected. When the airbag 304 squeezes the patient's area to be corrected, the second pressure sensor 302 can be squeezed and the pressure inside the airbag 304 can be fed back in real time. Next, when the pressure is below the threshold, the controller 14 starts the micro air pump 301 to work, so that the micro air pump 301 inflates the air bag 304 through the air tube 303. After the threshold is reached, the micro air pump 301 automatically stops pumping to avoid the patient's local skin being under pressure for a long time. This step automatically inflates the airbag 304, which can assist in correction, reduce pain in the patient's correction area, and improve the success rate of correction.

[0022] Please see Figure 4-8 As shown, this embodiment, based on the above embodiment, also includes an adjustment structure; The adjustment structure includes a sleeve 41, a spring clip 42, a slider 43, and a locking hole 44; The sleeve rod 41 is fixedly connected to the front end of the fixed frame 12, the spring buckle 42 is fixedly connected to the outside of the sleeve rod 41, the slider 43 is slidably connected to the outside of the sleeve rod 41, and the locking hole 44 is opened on the inner side wall of the slider 43.

[0023] The adjustment structure also includes a handle 45 and a spring post 46; The handle 45 is fixedly connected to the front end of the slider 43, and the spring post 46 is slidably connected to the inside of the handle 45; The interior of slider 43 and handle 45 are interconnected. Slider 43 is used to open the locking hole 44, and handle 45 is used to provide sliding space for spring post 46. Spring post 46 and locking hole 44 are set on the same central axis. Locking hole 44 is used to provide space for spring buckle 42 to engage. With the auxiliary cooperation between the sleeve rod 41 and the spring buckle 42, when the patient holds the handle 45 with both hands, he can release the limit formed between the sleeve rod 41 and the slider 43 by squeezing the spring post 46 with his fingers. The position of the slider 43 can be adjusted according to his own correction needs. Working principle: During the correction of the patient; First, the patient holds the handle 45 with both hands and presses the spring post 46 inside the handle 45. Since the handle 45 and the slider 43 are connected to each other, the spring post 46 can squeeze the spring buckle 42 that is engaged in the buckle hole 44. Next, the limiting position formed between the slider 43 and the sleeve 41 can be released. Hold the handle 45 and drive the slider 43 to slide along the trajectory of the sleeve 41 to the appropriate position. After releasing the pressure on the handle 45, the locking hole 44 and the spring buckle 42 can be engaged again, thereby limiting the slider 43. This step can help patients quickly and appropriately adjust the position of their hands according to their correction needs.
