Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an adjustable orthopedic rehabilitation clamping device. Background Technology

[0002] In orthopedic rehabilitation, clamping structures typically refer to medical devices or apparatuses used to fix, support, or protect bones, joints, and surrounding tissues. For some patients with arm fractures, clamping structures are needed to hold and fix the patient's arm, which helps maintain the limb position, ensures a smooth healing process, and thus guarantees the recovery effect of the patient's arm.

[0003] For example, Chinese patent CN219148131U discloses a fixation device for arm fractures. This device uses a screw to fix the lower part of the forearm fixation mold, so that after the patient's arm position is adjusted, the patient cannot move the forearm position slightly, thus ensuring the stability of the forearm. This solves the problem that the patient can still move the broken arm slightly through the elbow joint, which may easily cause injury to the broken arm and is not conducive to the recovery of the broken arm.

[0004] While existing clamping and fixation devices can improve the rehabilitation effect of patients' arms to a certain extent during use, in clinical application, the fracture site of the patient's arm will have a certain degree of swelling in the early stage of injury. As the patient's hand gradually recovers, the swelling of the arm will also subside. At this time, the gap between the clamping and fixation device and the patient's arm will gradually increase, causing the clamping and fixation device to loosen and thus affecting the clamping stability of the patient's arm. Summary of the Invention

[0005] To address the problem in existing technologies where the gap between the clamping device and the arm gradually increases as swelling subsides, affecting the stability of the arm clamping, this invention incorporates a compensation component.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above solution, by setting up a compensation component, the clamping range of the clamping device can be flexibly adjusted according to the patient's recovery speed and swelling. This not only ensures that the clamping device always keeps in close contact with the patient's arm, thus guaranteeing the rehabilitation effect of the patient's arm, but also provides a good clamping and fixation effect for the arms of different patients, thereby improving the application range of the clamping device to a certain extent.

[0019] This solution incorporates an air-guiding component, allowing the ejected gas to flow between the patient's arm and the air cushion during movement.

[0038] like Figures 1 to 8 As shown, this embodiment of the invention provides an adjustable orthopedic rehabilitation clamping device, including a first fixing frame 11 and a second fixing frame 14. The first fixing frame 11 and the second fixing frame 14 are elastically connected by an elastic band 15. An inflatable compensation component is provided inside the first fixing frame 11 to support the arm. The compensation component includes an air cushion 20, which is disposed on the bottom of the inner surface of the first fixing frame 11. An air storage chamber 27 is embedded in the air cushion 20. A piston groove 31 is provided inside the first fixing frame 11. The piston groove 31 is connected to the air storage chamber 27 through an air outlet pipe 30. A piston plate 32 is slidably connected inside the piston groove 31. A piston rod 33 is connected to one side of the piston plate 32. A through pipe 34 is provided inside the piston rod 33, making the piston rod 33 a tubular structure. One end of the piston rod 33 extends along the piston groove 31, passes through the first fixing frame 11, and extends out of the first fixing frame 11 to communicate with the outside. A pressure plate 35 is provided at one end of the piston rod 33 that extends out of the first fixed frame 11. One end of the piston rod 33, which is also one end of the through pipe 34, passes through the piston plate 32 and is connected to the piston groove 31. The other end of the piston rod 33, which is also the through pipe 34, passes through the pressure plate 35 and is connected to the outside. A control valve is provided inside the through pipe 34.

[0039] Both the first fixing frame 11 and the second fixing frame 14 are arc-shaped structures, and the first fixing frame 11 and the second fixing frame 14 are preferably made of flexible materials. A support plate 28 is vertically arranged inside the gas storage cavity 27, and a plurality of through holes 29 are evenly distributed along the length of the support plate 28.

[0040] By adopting the above technical solution, the first fixation frame 11 and the second fixation frame 14 are the main components of the clamping device. The elastic band 15 can elastically connect the first fixation frame 11 and the second fixation frame 14, so that the angle change between the first fixation frame 11 and the second fixation frame 14 can better adapt to the patient's arm. When clamping and reducing the fracture site of the arm through the fixation clamping device, the second fixation frame 14 is wrapped around the patient's upper arm, and the first fixation frame 11 is placed under the arm. The first fixation frame 11 plays a wrapping role for the patient's arm. The air cushion 20 inside the first fixation frame 11 will contact the patient's arm. The air cushion 20 is made of elastic material and can keep close to the patient's arm. The support plate 28 inside the air cushion 20 can improve the support performance of the air cushion 20. As the patient's arm gradually recovers, the swelling in the patient's arm will gradually subside. At this time, the operator pulls the piston rod 33 back and forth through the pressure plate 35. During the movement, the piston rod 33 will drive the piston plate 32 to move synchronously inside the piston groove 31. When the piston plate 32 moves closer to the pressure plate 35... During movement, a negative pressure is formed inside the piston groove 31. At this time, external air is drawn into the piston groove 31 through the through pipe 34 under the action of gas pressure. When the piston rod 33 drives the piston plate 32 to move in the opposite direction to the pressure plate 35, the piston plate 32 pushes the gas inside the piston groove 31. At this time, the gas inside the piston groove 31 enters the air storage chamber 27 inside the air cushion 20 through the air outlet pipe 30. The control valve set in the through pipe 34 can prevent the gas from being repelled out of the through pipe 34. The through hole 29 on the surface of the support plate 28 can ensure stable air flow inside the air storage chamber 27. The air cushion 20 is inflated by the injection of gas, thereby reducing the gap between the patient's arm and the first fixation frame 11. By setting the compensation component, the clamping range of the clamping device can be flexibly adjusted according to the patient's recovery speed and swelling. This not only ensures that the clamping device always keeps a close fit with the patient's arm, ensuring the rehabilitation effect of the patient's arm, but also provides a good clamping and fixation effect for the arms of different patients, thereby improving the application range of the clamping device to a certain extent.

[0041] like Figure 4 and Figure 6 As shown, an air guiding component is provided inside the elastic band 15. The air guiding component is used to blow air into the first fixing frame 11. The air guiding component includes a cavity 21 built into the elastic band 15. Multiple folding grooves 23 are formed on the upper surface of the elastic band 15. The multiple folding grooves 23 are evenly arranged in an array along the length direction of the elastic band 15, and each folding groove 23 is parallel to each other. The elastic band 15 has an arc-shaped structure. The extending direction of the folding grooves 23 is the width direction of the elastic band 15.

[0042] An air inlet 22 is provided on the upper surface of the elastic band 15, and the air inlet 22 is connected to the cavity 21. An air guide tube 24 is embedded inside the first fixing frame 11, and one end of the air guide tube 24 is connected to the cavity 21. Multiple nozzles 25 are evenly arranged in a linear array on the upper surface of the air cushion 20, and the air guide tube 24 is connected to the multiple nozzles 25. The air guide tube 24 has a Z-shaped structure.

[0043] By adopting the above technical solution, during the rehabilitation process, the patient's elbow joint needs to undergo appropriate flexion and extension to reduce the risk of arm muscle degeneration and atrophy. The folding groove 23 on the surface of the elastic band 15 ensures the support strength of the elastic band 15 while also reducing the bending resistance of the elastic band 15 to a certain extent. When the patient's elbow joint is flexed, the first fixation frame 11 and the second fixation frame 14 will compress the elastic band 15. At this time, the gas inside the elastic band 15 will enter the air duct 24 under pressure and be delivered to the nozzle 25 through the air duct 24, and then through several... The parallel nozzles 25 spray gas, which flows between the patient's arm and the air cushion 20, carrying away some heat and providing ventilation and heat dissipation. This keeps the temperature of the contact area between the patient's arm and the air cushion 20 within an appropriate range, reducing discomfort during prolonged wear of the clamping device and lowering the probability of infection and inflammation due to overheating. When the patient's arm is extended, external air enters the cavity 21 through the air inlet 22, keeping the elastic band 15 fully inflated.

[0044] like Figure 1 and Figure 8 As shown, a support assembly is connected between the first fixed frame 11 and the second fixed frame 14. The support assembly is used to support the first fixed frame 11 and the second fixed frame 14. The support assembly includes a moving groove 37. The outer surfaces of both sides of the first fixed frame 11 are provided with moving grooves 37. The two moving grooves 37 are symmetrically arranged. A sliding rod 36 is slidably connected in the moving groove 37. A pull rod 16 is rotatably connected to the outer surface of the sliding rod 36. A guide groove 17 is provided on the pull rod 16. The outer surfaces of both sides of the second fixed frame 14 are threadedly connected with locking rods 18. The two locking rods 18 are symmetrically arranged. The locking rods 18 pass through the guide groove 17 on the same side and are slidably connected to the guide groove 17. The two sets of locking rods 18, the two sets of pull rods 16 in the initial state, and the two sets of moving grooves 17 are all symmetrically arranged. A pull bar 44 is connected between the first fixing frame 11 and the second fixing frame 14. The pull bar 44 is made of elastic material. One end of the pull bar 44 is connected to the outer side wall of the first fixing frame 11, and the other end of the pull bar 44 is connected to the outer side wall of the second fixing frame 14 on the same side.

[0045] By adopting the above technical solution, the tie bar 44 between the first fixing frame 11 and the second fixing frame 14 can improve the stability of the clamping device. The first fixing frame 11 slides and supports the slide rod 36 through the moving groove 37, and the slide rod 36 rotates and supports the pull rod 16, so that the pull rod 16 can rotate around the slide rod 36 as the fulcrum. The locking rod 18 engages with the pull rod 16 through the guide groove 17, and the guide groove 17 and the locking rod 18 can slide relative to each other. When the guide groove 17 slides to a suitable position relative to the locking rod 18, the first fixing is completed. When the angle between the first fixed frame 11 and the second fixed frame 14 is appropriate, the guide groove 17 can be fixed by turning the locking rod 18, which in turn can fix the pull rod 16, so that the pull rod 16 and the second fixed frame 14 are engaged and fixed, thereby keeping the pull rod 16 and the second fixed frame 14 stable. By setting the support component, the pull rod 16 and the slide rod 36 can play a supporting and fixing role between the first fixed frame 11 and the second fixed frame 14, thereby further improving the stability and firmness of the clamping device during use.

[0046] like Figure 4 , Figure 5 and Figure 8 As shown, an adjustment assembly is provided on the first fixed frame 11. The adjustment assembly is used to adjust the resistance encountered by the first fixed frame 11 when rotating relative to the second fixed frame 14. The adjustment assembly includes a traction bar 38, which is made of elastic material. One end of the traction bar 38 is connected to the outer surface of the slide bar 36. Movable holes 43 are provided on the outer surfaces of both sides of the first fixed frame 11. The movable holes 43 are located on the same side of the moving groove 37 away from the second fixed frame 14. The two movable holes 34 are symmetrically arranged. A scroll 39 is rotatably connected inside the movable hole 43. One end of the scroll 39 passes through the movable hole 43 and is rotatably connected to the movable hole 43. The other end protrudes out of the movable hole 43 and protrudes from the outer surface of the first fixed frame 11. The scroll 39 is rotatably connected to the outer surface of the first fixed frame 11. The moving groove 37 is connected to the inside of the movable hole 43, and the size of the connection is smaller than the diameter of the scroll 39, so that the scroll 39 is restricted to rotating only within the movable hole 43. In one embodiment, one end of the movable hole 43 passes through the surface of the first fixed frame 11 and communicates with the outside, while the other end communicates with the movable slot 37 through a channel built into the first fixed frame 11. The channel allows the traction bar 38 to pass through.

[0047] The other end of the traction bar 38 is connected to the outer surface of the spool 39 on the same side. Multiple sets of limiting grooves 42 are provided on the spool 39. The multiple sets of limiting grooves 42 are evenly arranged in an array around the outer circumference of the spool 39. A sliding groove 40 is provided above the movable hole 43 and on the outer surface of the first fixing frame 11. The sliding groove 40 is connected to the movable hole 43. A limiting block 41 is slidably connected in the sliding groove 40. The limiting block 41 is adapted to the limiting groove 42. The length of the limiting block 41 is greater than the depth of the limiting groove 42. When the limiting groove 42 is aligned and connected with the sliding groove 40, the downward sliding limiting block 41 can make the bottom end of the limiting block 41 embed into the limiting groove 42, so that the limiting groove 42 and the limiting block 41 are engaged. When the bottom end of the limiting block 41 is engaged with the limiting groove 42, the spool 39 is fixed.

[0048] By adopting the above technical solution, as the patient's arm gradually recovers, the intensity of the patient's arm movement should also increase accordingly. To this end, an adjustment component is set up. When the patient's elbow joint is in extension and flexion motion and the locking rod 18 is not fixing the pull rod 16, the second fixing frame 14 pulls the slide rod 36 via the pull rod 16, causing the slide rod 36 to slide linearly within the moving groove 37. During the sliding process, the slide rod 36 pulls the traction bar 38. The slide rod 36 needs to overcome the elasticity of the traction bar 38 during movement, thus converting the elasticity of the traction bar 38 into resistance to the patient's elbow joint movement. When it is necessary to increase the movement resistance, the operator moves the limiting block 41 upwards along the inside of the sliding groove 40, causing the limiting block 41 to disengage from the limiting groove 42 on the surface of the scroll 39. Touching the patient's arm, the scroll 39 is rotated at a certain angle. During the rotation, the scroll 39 will wind the traction bar 38 around a certain length. At this time, the traction bar 38 will pull the slide bar 36 to move closer to the scroll 39. Then, the limiting block 41 will engage with the limiting groove 42 under the action of gravity. At this time, the length of the traction bar 38 inside the moving groove 37 will be shortened. When the patient's arm moves, the slide bar 36 needs to overcome greater resistance when moving the traction bar 38, thereby increasing the intensity of the patient's arm movement. By setting the adjustment component, the intensity of the arm movement can be flexibly adjusted according to the patient's arm rehabilitation progress, so that the clamping device can match the patient's rehabilitation process, effectively improving the convenience and functionality of the clamping device during use.

[0049] like Figure 1 and Figure 2 As shown, mounting holes 12 are provided on one side wall of the second fixing bracket 14 and on one side wall of the first fixing bracket 11. Straps 13 are provided on the other side wall of the second fixing bracket 14 and on the other side wall of the first fixing bracket 11. Straps 13 can pass through the mounting holes 12 and extend through the mounting holes 12. The outer surface of the straps 13 is provided with Velcro, which can be used to fix the straps 13.

[0050] Multiple through slots 19 are formed on the inner surfaces of the two side walls of the first fixing frame 11. The extending direction of the through slots 19 is the same as the length direction of the first fixing frame 11. The multiple sets of through slots 19 are evenly arranged in an array, and the through slots 19 on the two side walls are symmetrically distributed. Multiple sets of air guide grooves 26 are formed on the upper surface of the air cushion 20. The extending direction of the air guide grooves 26 is the same as the extending direction of the air cushion 20. The multiple sets of air guide grooves 26 are evenly arranged in an array, and the air guide grooves 26 are parallel to each other. The air cushion 20 is made of elastic material.

[0051] By adopting the above technical solution, the straps 13 on the surfaces of the first fixing frame 11 and the second fixing frame 14 are used to tie the clamping device to the outside of the arm. The straps 13 pass through the mounting holes 12 on the surfaces of the first fixing frame 11 and the second fixing frame 14, thereby enabling the clamping device to be quickly put on with Velcro. During the binding process, the through groove 19 on the inner side of the first fixing frame 11 can cause the first fixing frame 11 to undergo a certain degree of elastic deformation, thereby making the first fixing frame 11 fit more tightly with the patient's arm. At the same time, the through groove 19 and the air guide groove 26 help the air to circulate, thereby further improving the heat dissipation effect of the clamping device.

[0052] The workflow of the technical solution of this invention is as follows:

[0053] An adjustable orthopedic rehabilitation clamping device is used to clamp and reduce a fractured arm. A second fixation frame 14 is placed over the patient's upper arm, and a first fixation frame 11 is placed under the arm. The first fixation frame 11 wraps around the patient's arm. A strap 13 passes through mounting holes 12 on the surfaces of the first and second fixation frames 11 and 14, allowing for quick donning of the clamping device with Velcro. When the piston rod 33 moves the piston plate 32, the piston plate 32 pushes the gas inside the piston groove 31. The gas then enters the air storage chamber 27 inside the air cushion 20 through the air outlet pipe 30. This gas injection inflates the air cushion 20, reducing the gap between the patient's arm and the first fixation frame 11. The first fixation frame 11, in conjunction with the second fixation frame 14, provides support and reduction. When the elastic band 15 is compressed, the gas inside the elastic band 15 enters the air duct 24 under pressure. The gas is then delivered to the nozzle 25 through the air duct 24. The ejected gas can flow between the patient's arm and the air cushion 20, thereby carrying away some heat and providing ventilation and heat dissipation between the patient's arm and the air cushion 20. By turning the locking rod 18, the pull rod 16 and the second fixing frame 14 can be locked and fixed, thus keeping the pull rod 16 and the second fixing frame 14 stable. During the sliding process, the slide rod 36 pulls the traction bar 38. During the movement, the slide rod 36 needs to overcome the elasticity of the traction bar 38, thereby converting the elasticity of the traction bar 38 into resistance to the movement of the patient's elbow joint, so that the clamping device can match the patient's rehabilitation process.

[0054] In this solution, by setting up a compensation component, the clamping range of the clamping device can be flexibly adjusted according to the patient's recovery speed and swelling. This not only ensures that the clamping device always keeps a close fit to the patient's arm, thus guaranteeing the rehabilitation effect of the patient's arm, but also provides a good clamping and fixation effect for the arms of different patients, thereby improving the application range of the clamping device to a certain extent.

[0055] This solution incorporates an air-guiding component, allowing the ejected gas to flow between the patient's arm and the air cushion during movement. This airflow carries away some heat, providing ventilation and heat dissipation between the patient's arm and the air cushion. This keeps the temperature of the contact area between the patient's arm and the air cushion within an appropriate range, reducing discomfort during prolonged wear of the clamping device and also lowering the probability of infection and inflammation at the affected area due to overheating.

[0056] This solution incorporates an adjustment component that allows for the adjustment of the traction bar length via a roller. This enables flexible adjustments to the arm's movement intensity based on the patient's recovery progress, thus matching the clamping device with the patient's rehabilitation process and effectively improving the device's convenience and functionality during use.

[0057] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
