Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a wearable hunchback correction and rehabilitation training device. Background Technology

[0002] The spine is the supporting part of the human body structure and plays an important role in maintaining the normal physiological structure of the human body. It can effectively maintain the body's posture. However, with the development of society, the pressure brought by work and study is getting heavier and heavier. Most people will repeat a certain action for a long time or have incorrect posture, which will lead to the curvature of the spine, resulting in different degrees of changes in the shoulders and spine, leading to spinal strain and causing fatigue or discomfort.

[0003] Existing hunchback correction methods can only correct the posture and cannot be adjusted according to the user's height and body type. They can only massage a small area of ​​the back, completely omitting tense areas related to hunchback, such as the neck and lower back. Over time, the unmasked neck and lower back muscles will remain stiff, potentially leading to additional problems such as neck pain and lower back strain, failing to achieve the goal of relaxing the entire back area. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a wearable hunchback correction and rehabilitation training device. This solves the problem that existing hunchback correction devices can only correct the posture and cannot be adjusted according to the user's height and body type. They can only massage a small area of ​​the back, completely neglecting tense areas related to hunchback, such as the neck and lower back. Over time, the unmasked neck and lower back muscles will remain stiff, potentially leading to additional problems such as neck pain and lower back strain, failing to achieve the goal of full-area relaxation.

[0009] Preferably, a cylinder is fixedly connected to the inner wall of the fixed sleeve, and the output end of the cylinder is fixedly connected to the outer wall of the motor.

[0010] Preferably, each of the opposite sides of the connecting frame is fixedly connected to a connecting column, and the connecting columns are rotatably connected to each other.

[0011] Preferably, one end of the inclined rod is fixedly connected to a swing column, and one end of the swing column is fixedly connected to a massage disc.

[0012] Preferably, one end of the inclined rod is fixedly connected to a swing column, and one end of the swing column is fixedly connected to a massage disc.

[0013] Working principle: The user puts on the vest and stretches the first elastic band on the right outer wall and the second elastic band on the front left outer wall to fit their torso circumference. Then, the plastic buckle fixed at one end of the first elastic band and the plastic nut fixed at one end of the second elastic band are engaged to make the vest fit the torso tightly. At the same time, it ensures that the correction plate fixed at the back of the vest fits stably against the back, providing basic support for subsequent correction and training. When the pivot rotates, it drives the rotating rod to rotate. The stop pawl controls the movement, and the rotating rod drives the drive sprocket to rotate. The drive sprocket and the chain drive the driven sprocket to rotate, causing the rotating column to rotate. This causes the connecting block on the outer wall of the chain to move, which in turn moves the support plate and the fixed sleeve and telescopic sleeve to move, so that they can be aligned with the slot. The slot at the top massages the neck. The middle slot massages the back, while the bottom slot massages the waist. A cylinder drives a motor to move the telescopic sleeve along the inner wall of the fixed sleeve, providing guidance. The motor drives a diagonal rod to rotate, causing the swing column to perform an eccentric circular motion. The connecting ring guides and limits the swing column, causing the massage plate fixed at one end of the swing column to perform a reciprocating oscillating massage motion. During the oscillation, the massage plate presses and kneads the back muscles, promoting blood circulation in the back, neck, and waist, relieving muscle tension caused by hunchback, and stimulating muscles through regular massage to assist users in muscle rehabilitation training, enhance muscle strength, and ultimately achieve a synergistic effect of hunchback correction and rehabilitation training.

[0014] This invention provides a wearable hunchback correction and rehabilitation training device. It has the following beneficial effects: 1. This invention uses a transmission structure including a rotating shaft, rotating rod, sprocket, and chain to move the connecting block, support plate, fixed sleeve, and telescopic sleeve, allowing the massage disc to massage different parts of the neck, back, and waist. The invention also uses a winding belt, limiting sleeve, connecting disc, rotating shaft, limiting sleeve, slider, and sliding groove to pull and support the scoliosis. A cylinder drives a motor to make the massage disc perform reciprocating oscillating massage movements, pressing and kneading the back muscles. This promotes blood circulation in the back, neck, and waist, relieving muscle tension caused by hunchback, and the regular massage stimulates the muscles, assisting users in muscle rehabilitation training and strengthening muscle strength.

[0015] 2. This invention, by stretching the first elastic band and the second elastic band on the outer left side of the vest and engaging the plastic male buckle and the plastic female buckle, can adapt to the torso circumference of different users, making the vest fit the torso tightly. The correction plate fixed at the rear of the vest can stably fit the back, providing basic support for subsequent correction and training. Attached Figure Description

[0018] 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.

[0019] Example: like Figure 1-7As shown, this embodiment of the invention provides a wearable hunchback correction and rehabilitation training device, including a vest 1. The vest 1, made of a flexible and breathable material, serves as the wear base. A second elastic band 3 is fixedly connected to the left outer wall of the front end of the vest 1 via a sewing process, and a first elastic band 2 is similarly fixedly connected to the corresponding position on the right outer wall of the vest 1 via a sewing process. Both the first elastic band 2 and the second elastic band 3 are made of high-elasticity spandex material to ensure sufficient stretch to adapt to different torso circumferences. A plastic female buckle 4 is fixedly connected to the outer wall of the second elastic band 3 at the end furthest from the vest 1 via an injection molding process. At the end of the first elastic band 2 furthest from the vest 1, a plastic male buckle 5 is fixedly connected at the position corresponding to the plastic female buckle 4, with the protruding structure of the male buckle 5 matching the groove structure of the plastic female buckle 4 to ensure a stable engagement. A correction plate 6 is connected to the outer wall of the rear end of the vest 1 via a combination of Velcro and sewing. The corrective board 6 is made of lightweight ABS plastic. Its shape is adapted to the curve of the human back, and its thickness is 3-5mm, which ensures both support strength and avoids the feeling of pressure when wearing it.

[0020] Transmission and massage component assembly Assembly of the rotating shaft and rotating rod: A circular mounting hole is made inside the bottom right side of the straightening plate 6. The rotating shaft 7 is rotatably connected to the mounting hole through a bearing, ensuring that the rotating shaft 7 can rotate flexibly around its own axis. The rotating rod 11 is fixedly connected to the outer wall of the left end of the rotating shaft 7 by a flat key. The rotating rod 11 has an "L" shape and a length of 15-20cm, which is convenient for manual operation by the user.

[0021] Ratchet and stop pawl assembly: Ratchet 13 is fixedly connected to the outer right side of the rotating shaft 7 via a tight fit, with the teeth of ratchet 13 facing clockwise. Rotating rod 15 is fixedly connected to the outer right side of the straightening plate 6 above ratchet 13 via welding. Rotating rod 15 is cylindrical, and a stop pawl 14 is rotatably connected to its outer wall via a pin. The end of the stop pawl 14 is adapted to the teeth of ratchet 13, which can achieve unidirectional limiting and prevent the rotating shaft 7 from rotating counterclockwise.

[0022] Sprocket and chain assembly: Drive sprockets 16 are fixedly connected to the outer walls of both ends of the rotating rod 11 via flat keys. The drive sprockets 16 have 12-15 teeth. Another circular mounting hole is made inside the top of the straightening plate 6. The rotating column 10 is rotatably connected to this mounting hole via bearings. Driven sprockets 18 are fixedly connected to the outer walls of both ends of the rotating column 10 via flat keys. The number of teeth on the driven sprockets 18 is the same as that on the drive sprockets 16. The chain 17 is fitted between the drive sprockets 16 and the driven sprockets 18, ensuring a tight meshing between the chain 17 and the sprockets without slippage.

[0023] Massage actuator assembly: A connecting block 19 is bolted to the outer wall of the chain 17. The connecting block 19 has a cuboid structure, and its top is welded to a support plate 12. A fixing sleeve 20 is bolted to the top of the support plate 12. The fixing sleeve 20 is a hollow cylinder with a smooth inner wall. A telescopic sleeve 24 is slidably connected to the inner wall of the fixing sleeve 20. The outer diameter of the telescopic sleeve 24 is clearance-fitted with the inner diameter of the fixing sleeve 20 to ensure that the telescopic sleeve 24 can slide smoothly along the axis of the fixing sleeve 20.

[0024] Cylinder and motor assembly: Cylinder 23 is bolted to the bottom of the inner wall of the fixed sleeve 20. Cylinder 23 is a small miniature cylinder (10-15mm diameter, 20-30mm stroke), and its output end is threaded to the housing of motor 25. Motor 25 is a miniature DC motor (12V voltage, 100-200r / min speed), fixed to the outer wall of the telescopic sleeve 24, with the output shaft of motor 25 facing the straightening plate 6.

[0025] Massage disc drive assembly: A diagonal rod 26 is fixedly connected to the output end of motor 25 via a coupling. The angle between the diagonal rod 26 and the motor output shaft is 30-45°. The end of the diagonal rod 26 away from motor 25 is fixedly connected to a swing column 27 by welding. The swing column 27 is cylindrical, and one end is fixedly connected to the massage disc 21 by bolts. The surface of the massage disc 21 is decorated with silicone raised particles with a particle diameter of 3-5mm to enhance the massage feel. A connecting frame 22 is fixedly connected to the left side of the telescopic sleeve 24 by welding. The connecting frame 22 has a "U" shaped structure. Connecting columns 9 are fixedly connected to the inner wall of its opposite side by welding. A connecting ring 28 is rotatably connected between the two connecting columns 9 by a bearing. Fixed columns 29 are fixedly connected to both ends of the swing column 27 by welding. The fixed columns 29 are rotatably connected to the inside of the connecting ring 28 by bearings, allowing the swing column 27 to swing around the axis of the connecting ring 28.

[0026] Assembling the scoliosis correction component: A connecting plate 31 is bolted to the outer wall of the rear end of the correction plate 6. The connecting plate 31 is circular and has an annular groove 36 inside. Two to three sliders 35 are slidably connected to the inner wall of the groove 36, evenly distributed within the groove 36. A rotating shaft 30 is rotatably connected to the front end of the slider 35 via a bearing. A limiting ring 32 is tightly fitted to the outer ring of the rotating shaft 30 to limit the axial displacement of the rotating shaft 30. A take-up strap 34, made of high-strength nylon, is adhesively attached to the outer wall of the rear end of the rotating shaft 30. The other end of the take-up strap 34 is fixedly connected to a tension sleeve 33, made of elastic fabric. The tension sleeve 33 is engaged with the vest 1 for easy disassembly and can be used by different patients.

[0027] Device operation procedure Wearing and securing: The user puts both arms through the armholes of vest 1, making vest 1 fit snugly against the upper body. According to the user's torso circumference, stretch the first elastic band 2 and the second elastic band 3, and snap the plastic buckle 5 on the first elastic band 2 into the plastic female buckle 4 on the second elastic band 3. Adjust the tightness until vest 1 fits snugly against the torso without any pressure, and the higher arm goes through the stretch sleeve 33. At this time, the correction board 6 should fit the back curve completely, providing stable support for subsequent correction and massage.

[0028] Massage position adjustment: The user manually rotates the rotating rod 11 clockwise, which drives the rotating shaft 7 and the driving sprocket 16 to rotate clockwise synchronously. The driving sprocket 16 drives the driven sprocket 18 and the rotating column 10 to rotate via the chain 17, causing the chain 17 to move along the sprocket track, thereby driving the connecting block 19, the support plate 12, and the subsequent fixing sleeve 20, telescopic sleeve 24, and massage plate 21 to move as a whole. Depending on the area to be massaged (neck, back, waist), the massage plate 21 is aligned with the corresponding slot 8 on the outer wall of the front end of the correction plate 6 (the top slot corresponds to the neck, the middle slot to the back, and the bottom slot to the waist). At this time, the stop pawl 14, under its own weight, engages with the teeth of the ratchet 13, preventing the rotating shaft 7 from reversing and keeping the massage plate 21 in the target position.

[0029] Massage Action Execution: The cylinder 23 is activated, and its output pushes the motor 25 and the telescopic sleeve 24 along the inner wall of the fixed sleeve 20 towards the correction plate 6 until the massage disc 21 passes through the slot 8 and fits against the user's skin. The extension of the cylinder 23 is adjusted to control the pressure of the massage disc 21 (the pressure range is 5-10N to avoid excessive pressure). Then, the motor 25 is activated, driving the inclined rod 26 to rotate around the motor output shaft. Due to the angle between the inclined rod 26 and the motor output shaft, and the oscillating column 27 being rotatably connected to the connecting ring 28 via the fixed column 29, the inclined rod 26 drives the oscillating column 27 to reciprocate around the axis of the connecting ring 28, thereby causing the massage disc 21 to perform pressing and kneading actions on the skin. The massage frequency is consistent with the rotation speed of the motor 25 (100-200 times / minute).

[0030] Scoliosis Assisted Correction: For users with mild scoliosis, assisted correction can be achieved by adjusting the take-up strap 34. Manually push the slider 35 along the groove 36 of the connecting plate 31 to the opposite side of the scoliosis direction, then rotate the shaft 30. The take-up strap 34 is wound up on the shaft 30, and the tension sleeve 33 applies tension to the left side of the vest 1, thereby generating a slight corrective tension on the spine. The tension is controlled by the amount of take-up of the take-up strap 34 (the tension range is 3-8N to avoid excessive tension causing discomfort). The limit ring 32 can prevent the shaft 30 from shifting axially under the action of tension.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
