Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an easily detachable joint protection device for orthopedic care. Background Technology

[0002] Osteoarthritis is a chronic joint disease characterized by localized degeneration of articular cartilage, bone loss, osteophyte formation at joint margins, joint deformities, and subchondral bone densification. Osteoarthritis protective treatment garments are medical devices specifically designed to protect joints. They reduce joint load, alleviate pain, and prevent further damage by providing external support and restricting abnormal movements. These garments can also help patients perform appropriate muscle contraction training and joint flexibility exercises without aggravating their condition, thereby enhancing joint stability, promoting functional recovery, and slowing disease progression.

[0003] CN219000782 U discloses a bone and joint protective sleeve for clinical orthopedic treatment of bone and joints. By fixing the air bladder at the rear end of the protective pad, it is possible to reduce gaps and enhance the fit between the upper and lower protective plates as the air bladder gradually expands due to gas filling. At the same time, it can also apply pressure to the patient's joint area.

[0004] In this application, the joint protector requires the patient or another person to manually open the pads from side to side when putting them on or taking them off, making the operation rather cumbersome. In the later stages of rehabilitation, joints typically need to undergo active or passive movement within a certain range to gradually restore their functional flexibility, muscle strength, and proprioception. This process must strictly adhere to the principle of gradual progression, adjusting the range and intensity of movement according to individual recovery under the guidance of professionals. If the joint flexion is not properly restrained, exceeding the load that the current tissue healing can withstand, it can easily cause secondary soft tissue strain, or even worsen the inflammatory response, delaying the rehabilitation process. Therefore, this application proposes an easily removable joint protector for orthopedic care. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an easily detachable joint protection device for orthopedic care, in order to solve the technical problems mentioned in the background above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a removable joint protection device for orthopedic care, comprising a joint protection sleeve, wherein the joint protection sleeve is composed of four sets of fixing parts arranged symmetrically in an upper and lower shape and metal connecting plates. The outer walls of the upper and lower sets of fixing parts are positioned by means of the metal connecting plates. Each fixing part is composed of two sets of semi-protective plates that fit against the outer side of the limb. Each set of semi-protective plates has elastic bands at both ends for binding. The outer wall of each set of semi-protective plates is fixed with a rubber shell for positioning the metal connecting plates. The two ends of the rubber shell are curved and glued to the outer wall of the semi-protective plate. A rotating part connecting the upper and lower sets of metal connecting plates is provided at a symmetrical point. The rotating part includes a positioning disk for connecting two sets of upper and lower metal connecting plates. A base shaft is fixed to the outer end face of the positioning disk. Two sets of connecting metal plates, which are respectively fixed to the ends of the upper and lower metal connecting plates, are sleeved on the outer wall of the base shaft. A damping disk for increasing the friction between the two sets of connecting metal plates is provided between them. A face ring for constraining the lower connecting metal plate is sleeved on the outer wall of the base shaft near the end. A nut for limiting the face ring is connected to the end of the base shaft.

[0007] As a preferred technical solution, the damping disc includes a base disc sleeved on the outer wall of the base shaft. A spirally tapered plate is fixed to the end face of the base disc. A flexible rubber protrusion that can fit with the spirally tapered plate is fixed to the outer wall of the connecting metal plate located below. A constraint ring is fixed to the outer side of the spirally tapered plate at the end face of the base disc. The constraint ring ensures that a constant gap is maintained between the two sets of connecting metal plates.

[0008] As a preferred technical solution, the damping disc also includes a marker arrow to fix the position along the edge, and the curved outer wall of the base disc is provided with screws that can be connected to the positioning disc.

[0009] As a preferred technical solution, the rotating part further includes an arc-shaped reference line opened on the end face of the positioning disk. The reference line and the marking arrow cooperate with each other to control the rotation angle of the base disk. A screw hole for connecting screws is opened in an arc shape at the position opposite to the reference line.

[0010] As a preferred technical solution, a locking bolt is threadedly connected to the outer wall of the connecting metal plate below, the end of the locking bolt extends into the end face of the positioning plate, and an insertion hole is opened on the end face of the positioning plate at the position corresponding to the locking bolt.

[0011] As a preferred technical solution, the positioning disc is attached to one side of the limb with a knee pad, and the diameter of the knee pad is larger than the diameter of the positioning disc.

[0012] As a preferred technical solution, the semi-protective plate includes a breathable pad that fits against the surface of the limb. The inner side of the breathable pad has a rectangular array of breathable holes for ventilation and heat dissipation. Each set of breathable pads has staggered extension pads fixed at both ends.

[0013] As a preferred technical solution, the rubber shell is fixed to the outside of the breathable pad in a central position by sewing. The outer wall of the rubber shell is provided with positioning bolts for limiting the metal connecting plate. Each set of curved parts is provided with metal positioning shafts that can be rotatably connected on the upper and lower surfaces. The end of the elastic band is sewn onto the outer wall of the metal positioning shaft.

[0014] In summary, the present invention has the following main beneficial effects: This invention uses modular fixing parts to form a joint protective sleeve, and each fixing part can be disassembled and replaced independently, avoiding the situation where the whole structure is abandoned due to local damage. At the same time, it can realize the quick binding and disassembly of the half-plate. Its curved part can quickly recover, so that the breathable pad is straight, which makes it easy to quickly remove the protective sleeve manually without cumbersome direction adjustment, greatly simplifying the operation process of putting on and taking off. In addition, the application can dynamically adjust the device status according to different stages of rehabilitation treatment (early adaptation and later strengthening), thereby achieving precise control of the range of motion of the joints and intelligently adjusting the damping force that the limbs can withstand during flexion. This can effectively avoid secondary soft tissue damage caused by excessive flexion or extension of the joints or sudden load, and improve the safety and adaptability of the rehabilitation process.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of the present invention will now be described.

[0019] An easily removable joint protection device for orthopedic care, such as... Figures 1 to 8 As shown, the device includes a joint protection sleeve 100, which consists of four sets of fixing parts 110 arranged symmetrically in an upper and lower shape and a metal connecting plate 120. The outer walls of the upper and lower sets of fixing parts 110 are positioned by means of the metal connecting plate 120. The fixing part 110 consists of two sets of semi-protective plates 130 that fit against the outside of the limb. Each set of semi-protective plates 130 has elastic bands 134 for binding at both ends. Each set of semi-protective plates 130 has a rubber shell 136 fixed to the outer wall for positioning the metal connecting plate 120. The two ends of the rubber shell 136 are bent parts 137 and are glued to the outer wall of the semi-protective plate 130. A rotating part 200 connecting the upper and lower sets of metal connecting plates 120 is provided at the symmetrical point. The semi-protective plate 130 includes a breathable pad 131 that fits against the surface of the limb. The inner side of the breathable pad 131 has a rectangular array of breathable holes 132 for ventilation and heat dissipation. Each set of breathable pads 131 has extension pads 133 that are distributed in a staggered manner at both ends.

[0020] The rubber shell 136 is fixed to the outside of the breathable pad 131 by sewing. The outer wall of the rubber shell 136 is provided with positioning bolts 138 for limiting the metal connecting plate 120. Each set of curved parts 137 has metal positioning shafts 135 that can be rotatably connected on the upper and lower surfaces. The end of the elastic band 134 is sewn onto the outer wall of the metal positioning shaft 135. The end of the elastic band 134 is folded outward and fixed by Velcro.

[0021] As per the instruction manual Figures 1 to 3 As shown, each fixing part 110 can be disassembled and replaced independently, avoiding the situation where the entire structure is discarded due to partial damage. In addition, when not in use, the left and right half-protective plates 130 in the fixing part 110 can be brought close together and fit tightly, reducing the space occupied and making it easy to store and carry when going out; When the patient puts on the protective sleeve, first open the multiple elastic bands 134 located at the front to smoothly insert the lower limb and center it. Then, pass the end of each elastic band 134 through the inside of the metal positioning shaft 135, fold it outward, and tighten it appropriately to ensure that the protective sleeve fits tightly against the lower limb. (At the same time, the curved parts 137 at both ends deform inward, allowing the breathable pad 131 to fit fully against the surface of the limb. When removing the sleeve later, the curved parts 137 can quickly return to their original shape after contact with the restraining effect of the elastic bands 134, making the breathable pad 131 straight and easy to remove the protective sleeve manually.) Finally, secure it with Velcro, and the protective sleeve can be worn on the outside of the lower limb.

[0022] The rotating part 200 includes a positioning disk 210 for connecting two sets of upper and lower metal connecting plates 120. A base shaft 220 is fixed to the outer end face of the positioning disk 210. Two sets of connecting metal plates 150 are sleeved on the outer wall of the base shaft 220 and respectively fixed to the ends of the upper and lower metal connecting plates 120. A damping disk 230 is provided between the two sets of connecting metal plates 150 to increase the friction between them. A face ring 240 for constraining the lower connecting metal plate 150 is sleeved on the outer wall of the base shaft 220 near the end. A nut 221 for limiting the face ring 240 is connected to the end of the base shaft 220.

[0023] The damping disc 230 includes a base disc 231 sleeved on the outer wall of the base shaft 220. A spiral-shaped progressive plate 233 is fixed on the end face of the base disc 231. A flexible rubber protrusion 160 that can fit with the spiral-shaped progressive plate 233 is fixed on the outer wall of the connecting metal plate 150 located below. A constraint ring 234 is fixed on the outer side of the spiral-shaped progressive plate 233 at the end face of the base disc 231. The constraint ring 234 keeps a constant gap between the two sets of connecting metal plates 150.

[0024] The positioning plate 210 has a slot 211 on its upper part and the connecting metal plate 150 above it is fixed with a retaining strip 170 at the position corresponding to the slot 211; the two work together to fix it.

[0025] A locking bolt 250 is threadedly connected to the outer wall of the lower connecting metal plate 150. The end of the locking bolt 250 extends into the end face of the positioning plate 210. An insertion hole 280 is provided on the end face of the positioning plate 210 at the position corresponding to the locking bolt 250.

[0026] In the early stages of rehabilitation therapy, when it is necessary to immobilize and restrain the lower limbs to limit joint movement, please refer to the appendix. Figure 1 and Figure 5 The assembly method shown involves using a tool to gradually screw the movable locking bolt 250 into the reserved hole of the connecting metal plate 150 along the thread track, so that its end is precisely embedded in the insertion hole 280. The joint protective sleeve 100 presents an integral fixed structure, which cannot rotate around the rotating part 200 in any direction, thereby effectively limiting the unintended movement of the joint; it can provide reliable stability support in the early stage of rehabilitation and avoid secondary damage caused by accidental activities. During the exercise training phase, the locking bolt 250 can be removed, allowing the two sets of fixing parts 110 in the lower half to rotate smoothly around the base axis 220 under the synergistic action of the metal connecting plate 120 and the connecting metal plate 150. This allows the patient's lower limbs to perform walking or bending movements, thereby achieving the purpose of rehabilitation training; as per the instruction manual. Figure 6 and Figure 7 As shown, the flexible rubber protrusion 160 rotates synchronously with the connecting metal plate 150. As the gap between the spiral tapered plate 233 and the flexible rubber protrusion 160 gradually narrows during rotation, the damping effect generated during rotation continuously increases. Therefore, when the lower limb rotates in conjunction with the fixed part 110 of the lower half, the damping experienced gradually increases. At the same time, the rotation angle is naturally limited by the mechanical design, effectively avoiding lower limb strain that may be caused by excessive rotation amplitude. This ensures the safety and progressiveness of the training process and helps users gradually recover lower limb function. The damping disc 230 also includes a marker arrow 232 for fixing the position along the edge. The curved outer wall of the base disc 231 is provided with screws that can be connected to the positioning disc 210. The rotating part 200 also includes a reference line 270 that is arc-shaped and opened on the end face of the positioning disc 210. The reference line 270 and the marker arrow 232 cooperate with each other to control the rotation angle of the base disc 231. A screw hole 260 for connecting screws is opened in an arc shape at the position opposite to the reference line 270.

[0027] The base plate 231 can be rotated and repositioned according to the patient's actual needs, thereby adjusting the allowable rotation range of the two sets of fixing parts 110 in the lower half. The operator can manually release the locking effect of the base plate 231 (i.e., rotate to remove the screw, and then re-fix it after reaching the designated position), so that it can rotate around the base shaft 220 as the central axis. By observing the correspondence between the marked arrow 232 and the reference line 270, its rotation angle can be precisely controlled. As the base plate 231 rotates, the spiral gradually rising plate 233 on its surface will also rotate synchronously, thereby changing the contact path length and relative position between it and the flexible rubber protrusion 160 to adapt to the rehabilitation training of heat exchange at different stages.

[0028] Please refer to this carefully. Figure 5 and Figure 6 The positioning disc 210 is attached to one side of the limb with a knee pad 140 glued on it. The diameter of the knee pad 140 is larger than that of the positioning disc 210.

[0029] When the joints of the limbs are bent, the positioning disc 210 will not come into contact with the surface of the limb, thereby avoiding unnecessary friction or pressure on the skin or soft tissues and improving the comfort and safety of use.
