Description

Technical Field

[0001] This invention relates to the field of pain relief technology, and more particularly to a pain relief device for pain management. Background Technology

[0002] With the increasing demand for exercise among modern people, more and more people are entering the field of exercise, and the forms of exercise are becoming more and more diverse. People occasionally suffer from abrasions and other injuries of varying degrees, and pain relief devices have become an essential tool. These devices can not only relieve pain but also massage the body, making the parts that need relief more comfortable.

[0003] Existing fixed-shape heat therapy braces (such as knitted heat therapy elbow sleeves and silicone heating pads) mostly adopt a preset size and curvature design. Their support structure is a rigid or semi-rigid fixed shape, which cannot be adaptively adjusted according to the thickness and curvature of the patient's elbow joint. This results in gaps caused by the size being too large or too small, which drastically reduces the heat transfer efficiency and the relief effect. In view of this, a pain relief device for pain management is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adaptively adjust to the thickness and curvature of the patient's elbow joint, resulting in gaps due to the size being too large or too small, causing a sharp drop in heat transfer efficiency and reduced relief effect. Therefore, this invention proposes a pain relief device for pain management.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: A pain relief device for pain management includes a support ring, with connection ports fixedly provided at both ends of the support ring. The support ring and the connection ports are symmetrically distributed about the axis of the support ring, and an adjustment component is provided on the outer wall of the support ring. The adjustment component includes; A drive plate slides on the outer wall of the support ring, and a first arc-shaped plate is fixedly connected to the inner wall of the drive plate. A drive shaft is provided inside the thicker end of the first arc-shaped plate, and drive grooves are opened at both ends of the drive plate, and drive gears are provided inside the drive grooves. A connecting ring has a second arc-shaped plate on its outer wall, which fits against the outer wall of a first arc-shaped plate. The second arc-shaped plate and the first arc-shaped plate are arranged in a mirror image. A driven plate is slidably disposed at both ends of the driving plate, and the inner wall of the driven plate is slidably connected to the support ring. A gear groove is provided at the upper end of the driven plate, and a driving gear is rotatably disposed inside the even-numbered gear grooves. An inclined gear groove is provided at the bottom of the driven plate. A sliding groove is provided inside the connecting port, and a folding ring is engaged inside the sliding groove. Pushing teeth are provided at both ends of the folding ring, and the pushing teeth are mirror-fitted with the inclined gear groove.

[0006] Preferably, two driven plates are provided at both ends of the outer wall of the support ring, and a driving plate is provided between the two driven plates, with the outer walls of the driven plates and the driving plate on the same horizontal plane.

[0007] Preferably, a protective ring is fixedly provided on the outer wall of the drive plate, and the height of the protective ring is higher than that of the drive plate.

[0008] Preferably, the connecting plate has a movable cavity inside, and a movable plate is slidably disposed inside the movable cavity. The outer wall of the movable plate is provided with a rack, and the rack is distributed in an array along the sliding direction of the movable plate. A rotating groove is provided at the center of the second arc-shaped plate on the outer wall of the connecting plate, and the drive shaft is located inside the rotating groove. A heating module is provided on the inner wall of the movable plate.

[0009] Preferably, a connecting shaft is provided on one side of the outer wall of the connecting port, and two identical and symmetrical support rings are fixedly connected to both sides of the connecting shaft, and the structures at both ends of the outer wall of the support rings are the same.

[0010] Preferably, the structure provided on the inner wall of the driven plate is the same as the structure provided on the inner wall of the drive plate.

[0011] Preferably, an elastic plate is provided between the two connection ports located near the center of the support ring, and the elastic plate and the folding ring are arranged symmetrically about the axis of the connection ports.

[0012] Preferably, the support ring has an adhesive layer inside, and the outer wall of the adhesive layer is in contact with the heating module.

[0013] Preferably, the bonding layer is made of high-temperature resistant synthetic fiber cloth.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. After the elbow joint is placed inside the two symmetrical support rings, the drive plate is pushed, causing it to slide axially along the outer wall of the support ring. Simultaneously, the drive gears in the drive grooves on both sides of the drive ring rotate synchronously, precisely meshing with the gear grooves at the upper end of the driven plate. This drives the two driven plates to move synchronously along the outer wall of the support ring towards the elbow joint. As the driven plates move, the first arc-shaped plate fixed to the inner wall of the drive plate moves synchronously with the drive plate, and its thicker end slides radially along the arc surface of the second arc-shaped plate. Since the first and second arc-shaped plates are mirror images of each other, the sliding of the first arc-shaped plate will generate a centripetal thrust on the second arc-shaped plate. The connecting ring is pushed to retract towards the elbow joint. When the elbow joint flexes and extends, the change in the curvature of the elbow joint will generate radial extrusion force on the folding ring inside the connecting port. The folding ring folds inward around its own axis, and the pushing teeth at both ends slide towards the driven plate with the folding action. The inclined structure of the pushing teeth and the inclined gear groove at the bottom of the driven plate form an inclined guide transmission, which in turn pushes the inclined surface of the pushing teeth to press against the inner wall of the inclined gear groove, causing the driven plate to rotate around the outer wall of the support ring. This further adjusts the space inside the support ring, making the heating module inside the support ring fit the elbow joint better and achieve better relief.

[0015] 2. The moving cavity inside the connecting plate provides a stable sliding track for the moving plate. The racks on the outer wall of the moving plate are arranged in an array along the sliding direction. When the drive shaft rotates, it can drive the moving plate to slide smoothly along the moving cavity through meshing with the racks. The racks drive the moving plate to slide to the outside of the elbow joint, so that the heating module on the inner wall can accurately cover the pain point of the lateral epicondyle of the humerus, while increasing the area for pain relief.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] Example: This example provides a pain relief device for pain management, see [link to example]. Figure 1-7 Specifically, it includes a support ring 1, with connection ports 11 fixedly provided at both ends of the support ring 1. The support ring 1 and the connection ports 11 are symmetrically distributed about the axis of the support ring 1, and an adjustment component 2 is provided on the outer wall of the support ring 1. Adjustment component 2 includes; Drive plate 22 slides on the outer wall of support ring 1, and a first arc plate 221 is fixedly connected to the inner wall of drive plate 22. A drive shaft 222 is provided inside the thicker end of the first arc plate 221, and drive grooves 223 are opened at both ends of drive plate 22, and drive gears 224 are provided inside the drive grooves 223. The connecting ring 24 has a second arc-shaped plate 23 on its outer wall, and the outer wall of the second arc-shaped ring is in contact with the outer wall of the first arc-shaped plate 221. The second arc-shaped plate 23 and the first arc-shaped plate 221 are arranged in a mirror image. The driving plate 22 has driven plates 3 slidably arranged at both ends, and the inner wall of the driven plate 3 is slidably connected to the support ring 1. The driven plate 3 has a gear groove 31 at its upper end, and an even number of gear grooves 31 are rotatably arranged with a driving gear 224 inside. The driven plate 3 has a sloped gear groove 32 at its bottom. The connecting port 11 has a sliding groove 13 inside, and a folding ring 5 is engaged inside the sliding groove 13. The folding ring 5 has push teeth 51 at both ends, and the push teeth 51 are mirror-fitted with the sloped gear groove 32. In this optional embodiment, after the elbow joint is placed inside the two symmetrical support rings 1, the drive plate 22 is pushed to slide axially along the outer wall of the support ring 1. At the same time, the drive gears 224 in the drive grooves 223 on both sides of the drive ring rotate synchronously. The drive gears 224 precisely mesh with the gear grooves 31 at the upper end of the driven plate 3, thereby driving the two driven plates 3 to move synchronously along the outer wall of the support ring 1 towards the elbow joint. While the driven plates 3 move, the first arc-shaped plate 221 fixed to the inner wall of the drive plate 22 moves synchronously with the drive plate 22. Its thicker end slides radially along the arc surface of the second arc-shaped plate 23. Since the first arc-shaped plate 221 and the second arc-shaped plate 23 are mirror images of each other, the sliding of the first arc-shaped plate 221 will affect the second arc-shaped plate 23. The forming plate 23 generates a centripetal thrust, pushing the connecting ring 24 to contract towards the elbow joint. When the elbow joint flexes and extends, the change in the curved surface of the elbow joint will generate a radial extrusion force on the folding ring 5 inside the connecting port 11. The folding ring 5 folds inward with its own axis as the fulcrum. The pushing teeth 51 at both ends slide towards the driven plate 3 with the folding action. The inclined structure of the pushing teeth 51 and the inclined gear groove 32 at the bottom of the driven plate 3 form an inclined guide transmission, thereby pushing the inclined surface of the pushing teeth 51 to press against the inner wall of the inclined gear groove 32, causing the driven plate 3 to rotate around the outer wall of the support ring 1, further adjusting the space inside the support ring 1, so that the heating module 252 set inside the support ring 1 fits the elbow joint better and achieves better relief. Optionally, two driven plates 3 are provided at both ends of the outer wall of the support ring 1, and a driving plate 22 is provided between the two driven plates 3. The outer walls of the driven plates 3 and the driving plate 22 are on the same horizontal plane. In this optional embodiment, when the drive plate 22 drives the driven plate 3 to move via the drive gear 224, the two driven plates 3 are symmetrically distributed around the drive plate 22. They can synchronously receive the force transmitted by the drive plate 22 to adjust the space inside the support ring 1, ensuring the balance of force during wearing. When the drive plate 22 slides along the axial direction of the support ring 1, the driven plates 3 on both sides can move towards the elbow joint at the same speed and amplitude along the outer wall of the support ring 1 under the drive of the drive gear 224. This avoids the situation where one side is adjusted to the correct position while the other side still has a gap. For patients with thicker elbows, the synchronous contraction of the two driven plates 3 can ensure that the heating module 252 inside the support ring 1 approaches the joint evenly from both sides. For patients with thinner elbows, the synchronous expansion of the two driven plates 3 can prevent the heating module 252 from detaching from the pain point due to unilateral relaxation, thus ensuring the stability of the treatment effect. Optionally, a protective ring 21 is fixedly provided on the outer wall of the drive plate 22, and the height of the protective ring 21 is higher than that of the drive plate 22; In this optional embodiment, since the pain management device is used in various scenarios, dust in the air and sweat produced by patients when wearing it can easily adhere to the surface of the drive gear 224 if they enter the drive groove 223. This long-term accumulation can cause gear meshing to become stuck, or the sweat can corrode the gear material, affecting the adjustment accuracy or even causing the adjustment component 2 to fail. By using the protective ring 21, which is higher than the drive plate 22 and fits tightly against the outer wall of the drive plate 22, a closed protective space can be formed, which can effectively prevent dust and sweat from entering the drive groove 223 and improve the service life of the device. Optionally, a movable cavity 241 is provided inside the connecting plate, and a movable plate 25 is slidably disposed inside the movable cavity 241. A rack 251 is provided on the outer wall of the movable plate 25, and the rack 251 is distributed in an array along the sliding direction of the movable plate 25. A rotating groove 231 is provided at the center of the second arc-shaped plate 23 provided on the outer wall of the connecting plate, and the drive shaft 222 is located inside the rotating groove 231. A heating module 252 is provided on the inner wall of the movable plate 25. In this optional embodiment, the movable cavity 241 inside the connecting plate provides a stable sliding track for the movable plate 25. The racks 251 on the outer wall of the movable plate 25 are arranged in an array along the sliding direction. When the drive shaft 222 rotates, it can drive the movable plate 25 to slide smoothly along the movable cavity 241 through meshing with the racks 251. The racks 251 drive the movable plate 25 to slide to the outside of the elbow joint, so that the heating module 252 on the inner wall can accurately cover the pain point of the lateral epicondyle of the humerus, while increasing the area for relieving pain. Optionally, a connecting shaft 12 is provided on one side of the outer wall of the connecting port 11, and two identical and symmetrical support rings 1 are fixedly connected to both sides of the connecting shaft 12, and the structures provided at both ends of the outer wall of the support rings 1 are the same. In this optional embodiment, the frame structure formed by the double support rings 1 and the connecting shaft 12 has excellent impact resistance. When the patient accidentally collides with the device, the double support rings 1 can buffer the impact force through symmetrical deformation. At the same time, the connecting shaft 12 can also effectively connect the two support rings 1, facilitating flipping. Furthermore, when the patient places their elbow joint inside the double support rings 1, adjusting the drive plate 22 of either support ring 1 will cause the other support ring 1 to synchronously complete actions such as engagement of the drive gear 224, movement of the driven plate 3, and retraction of the connecting ring 24 under the linkage of the connecting shaft 12, forming a synchronous adjustment. The joint characteristics ensure that the clamping force of the double support ring 1 on the elbow joint and the coverage of the heating module 252 always remain symmetrical and consistent. The double support ring 1 can simultaneously and accurately fit the heating module 252 to the pain points on both sides, avoiding the situation where one side fits well while the other side has gaps when adjusting with a single ring, which greatly improves the pain relief effect. In addition, the symmetrical structure of the double support ring 1 can also adapt to the natural physiological curvature of the elbow joint. When the patient performs slight flexion and extension, the double rings can simultaneously adjust the internal space with the change of the joint curvature, always maintaining a close fit with the joint, avoiding local heat leakage or compression problems caused by insufficient adaptation of a single ring. Optionally, the structure provided on the inner wall of the driven plate 3 is the same as the structure provided on the inner wall of the drive plate 22; In this optional embodiment, after the inner wall of the driven plate 3 adopts the same structure as the inner wall of the drive plate 22, when the drive gear 224 meshes with the gear groove 31 of the driven plate 3 and drives it to move, the thicker end of the first arc plate 221 inside the driven plate 3 slides radially along the arc surface of the second arc plate 23. Since the first arc plate 221 and the second arc plate 23 are mirror images of each other, the sliding of the first arc plate 221 will generate a centripetal thrust on the second arc plate 23, pushing the connecting ring 24 to retract towards the elbow joint, thereby clamping the elbow joint at multiple positions and ensuring wearing comfort. Optionally, an elastic plate 52 is provided between the two connection ports 11 located near the center of the support ring 1, and the elastic plate 52 and the folding ring 5 are arranged symmetrically about the axis of the connection ports 11. In this optional embodiment, the elastic plate 52 and the folding ring 5 are symmetrically arranged. When the elbow joint deforms, the curvature of the outer and inner sides of the elbow joint will change synchronously. At this time, the symmetrically arranged elastic plate 52 and folding ring 5 will adapt synchronously along the joint movement direction. The elastic plate 52 near the outer side of the elbow joint is stretched, so that the elastic plate 52 plays a supporting role. Optionally, the support ring 1 is provided with an adhesive layer 4 inside, and the outer wall of the adhesive layer 4 is in contact with the heating module 252; In this optional embodiment, when the internal space of the support ring 1 is adjusted by the drive plate 22, the bonding layer 4 can be stretched synchronously with the contraction of the support ring 1, and after stretching, it can still maintain a tight fit with the heating module 252 and the support ring 1, and will not wrinkle or tear due to the size change of the support ring 1. This ensures that the heating module 252 can always adapt to the adjusted size of the support ring 1 through the bonding layer 4, cover the elbow joint pain area of ​​patients of different body types, achieve better relief, and at the same time reduce the occurrence of burns. Optionally, the bonding layer 4 is made of high-temperature resistant synthetic fiber cloth; In this optional embodiment, the high-temperature resistant synthetic fiber cloth has excellent heat conduction and buffering properties, which can effectively transfer the heat of the heating module 252 to the painful area, and avoid the direct "concentrated burst" of heat. The porous structure inside the fiber cloth can form a "heat buffer layer", which allows the heat to spread evenly along the cloth surface, preventing local high temperature caused by "point contact" between the heating module 252 and the skin, thereby reducing the risk of burns to middle-aged and elderly patients and patients with sensitive skin from the root.
