[0038] As shown in FIG. 1, Figures 1 to 8 The adjustable orthopedic rehabilitation clamping device provided by the embodiment of the present application comprises 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 through an elastic belt 15, the first fixing frame 11 is provided with a compensating assembly capable of being inflated, and the compensating assembly is used for supporting an arm. The compensating assembly comprises an air cushion 20, the air cushion 20 is arranged on the bottom of the inner surface of the first fixing frame 11, the air cushion 20 is embedded with a gas storage cavity 27, the first fixing frame 11 is internally provided with a piston groove 31, the piston groove 31 is communicated with the gas storage cavity 27 through a gas outlet pipe 30, a piston plate 32 is slidably connected in the piston groove 31, one side of the piston plate 32 is connected with a piston rod 33, the piston rod 33 is provided with a through pipe 34, the through pipe 34 penetrates the piston rod 33 and makes the piston rod 33 present a tubular structure. One end of the piston rod 33 extends along the piston groove 31, penetrates the first fixing frame 11 and extends out of the first fixing frame 11 to be communicated with the outside. The end of the piston rod 33 extending out of the first fixing frame 11 is provided with a pressing plate 35, one end of the piston rod 33, i.e. one end of the through pipe 34, penetrates the piston plate 32 and is communicated with the piston groove 31, the other end of the piston rod 33, i.e. the other end of the through pipe 34, penetrates the pressing plate 35 and is communicated with the outside; the through pipe 34 is provided with a control valve.

[0039] The first fixing frame 11 and the second fixing frame 14 are both arc-shaped structures, and the first fixing frame 11 and the second fixing frame 14 are preferably made of flexible material. A supporting plate 28 is vertically arranged in the gas storage cavity 27, and a plurality of through holes 29 are uniformly arranged along the length direction of the supporting plate 28.

[0040] By adopting the above technical scheme, the first fixing frame 11 and the second fixing frame 14 are main components of the clamping device, the elastic belt 15 can elastically connect the first fixing frame 11 and the second fixing frame 14, so that the angle change between the first fixing frame 11 and the second fixing frame 14 can better adapt to the arm of the patient. When the arm fracture part is clamped and reset by the fixed clamping device, the second fixing frame 14 is wrapped around the upper arm of the patient, and the first fixing frame 11 is placed on the lower side of the arm. The first fixing frame 11 plays a wrapping role on the patient's arm. The air cushion 20 inside the first fixing frame 11 will be in contact with the patient's arm. The air cushion 20 is made of elastic material and can closely fit 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 of the patient's arm will gradually subside. At this time, the operator reciprocally pulls the piston rod 33 through the pressing plate 35. The piston rod 33 will drive the piston plate 32 to move synchronously in the piston groove 31 during movement. When the piston plate 32 moves towards the side close to the pressing plate 35, a negative pressure will be formed in the piston groove 31. At this time, the external air will be sucked 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 of the pressing plate 35, the piston plate 32 will push the gas in the piston groove 31. At this time, the gas in the piston groove 31 will enter the gas storage cavity 27 inside the air cushion 20 through the gas outlet pipe 30. The control valve arranged in the through pipe 34 can prevent the gas from being expelled outward from the through pipe 34. The through hole 29 on the surface of the support plate 28 can ensure the stable circulation of air in the gas storage cavity 27. The injection of gas makes the air cushion 20 inflate and expand, thereby reducing the gap between the patient's arm and the first fixing frame 11. By arranging the compensation assembly, the clamping range of the clamping device can be flexibly adjusted according to the recovery speed and swelling condition of the patient. Not only can the clamping device always closely fit the patient's arm to ensure the rehabilitation treatment effect of the patient's arm, but also can have a good clamping and fixing effect on the arms of different patients, thereby improving the application range of the clamping device to a certain extent.

[0041] As shown in Figure 4 and Figure 6 , the elastic belt 15 is provided with an air guide assembly. The air guide assembly is used to blow air into the first fixing frame 11. The air guide assembly includes a cavity 21 arranged in the elastic belt 15. A plurality of folding grooves 23 are formed on the upper surface of the elastic belt 15. The plurality of folding grooves 23 are uniformly arranged along the length direction of the elastic belt 15 and are parallel to each other. The elastic belt 15 is in an arc shape.

[0042] The upper surface of the elastic band 15 is provided with an air inlet hole 22, the air inlet hole 22 is communicated with the cavity 21, the first fixed frame 11 is embedded with a gas guide pipe 24, one end of the gas guide pipe 24 is communicated with the cavity 21, the upper surface of the air cushion 20 is linearly and uniformly provided with a plurality of nozzles 25, the gas guide pipe 24 is communicated with the plurality of nozzles 25, and the gas guide pipe 24 is in a Z-shaped structure.

[0043] By adopting the above technical scheme, in the rehabilitation process of the patient's arm, the elbow joint needs to be appropriately bent and stretched to reduce the risk of muscle atrophy and degeneration of the arm. The folding groove 23 provided on the surface of the elastic band 15 can reduce the bending resistance of the elastic band 15 to a certain extent while ensuring the supporting strength of the elastic band 15. When the patient's elbow joint is bent, the first fixed frame 11 cooperates with the second fixed frame 14 to extrude the elastic band 15. At this time, the gas in the elastic band 15 will enter the inside of the gas guide pipe 24 under the action of pressure, and the gas will be transported to the nozzles 25 through the gas guide pipe 24. Then, the gas is sprayed out through the plurality of groups of parallel nozzles 25. The sprayed gas can flow between the patient's arm and the air cushion 20, thereby taking away part of the heat and ventilating and cooling the patient's arm and the air cushion 20, so that the temperature of the contact part between the patient's arm and the air cushion 20 can be maintained within an appropriate range. Not only can the discomfort during long-term wearing of the clamping device be reduced, but also the probability of infection and inflammation of the affected area due to overheating can be reduced. When the patient's arm is stretched, the external air will enter the inside of the cavity 21 through the air inlet hole 22, so that the elastic band 15 always maintains a full state.

[0044] As shown in Figure 1 and Figure 8 , the first fixed frame 11 and the second fixed frame 14 are connected with a support assembly, the support assembly is used for supporting the first fixed frame 11 and the second fixed frame 14, the support assembly comprises a moving groove 37, the outer surface of the two sides of the first fixed frame 11 is provided with the moving groove 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 on the outer surface of the sliding rod 36, a guide groove 17 is provided on the pull rod 16, the outer surface of the two sides of the second fixed frame 14 is threadedly connected with a locking rod 18, the two locking rods 18 are symmetrically arranged, the locking rod 18 penetrates through the same side guide groove 17 and is slidably connected with the guide groove 17, the two groups of locking rods 18, the two groups of pull rods 16 in the initial state and the two groups of moving grooves 17 are symmetrically arranged. The first fixed frame 11 and the second fixed frame 14 are connected with a stay 44, the stay 44 is made of elastic material, one end of the stay 44 is connected with the outer side wall of the first fixed frame 11, the other end of the stay 44 is connected with the outer side wall of the same side second fixed frame 14.

[0045] By adopting the above technical scheme, the stay 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 is supported by the sliding groove 37 for the sliding of the slide rod 36, and the slide rod 36 supports the rotation of the pull rod 16, so that the pull rod 16 can rotate around the slide rod 36 as a fulcrum. The locking rod 18 is in clamping contact 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 is slid to a suitable position relative to the locking rod 18, that is, when the angle between the first fixing frame 11 and the second fixing frame 14 is suitable, the guide groove 17 can be fixed by twisting the locking rod 18, and the pull rod 16 can be fixed, so that the pull rod 16 and the second fixing frame 14 are clamped and fixed, thereby keeping the pull rod 16 and the second fixing frame 14 stable. By providing the supporting assembly, the first fixing frame 11 and the second fixing frame 14 can be supported and fixed through the cooperation of the pull rod 16 and the slide rod 36, thereby further improving the stability and firmness of the clamping device during use.

[0046] As shown in Figure 4 , Figure 5 and Figure 8 , the first fixing frame 11 is provided with an adjusting assembly for adjusting the resistance of the first fixing frame 11 when rotating relative to the second fixing frame 14. The adjusting assembly includes a traction strip 38 made of elastic material. One end of the traction strip 38 is connected to the outer surface of the slide rod 36. The outer surfaces of the two sides of the first fixing frame 11 are each provided with a movable hole 43. The movable hole 43 is located on the side of the moving groove 37 away from the second fixing frame 14 on the same side, and the two movable holes 34 are symmetrically arranged. A reel 39 is rotatably connected in the movable hole 43. One end of the reel 39 penetrates into the movable hole 43 and is rotatably connected with the movable hole 43, and the other end penetrates out of the movable hole 43, that is, protrudes from the outer surface of the first fixing frame 11. The reel 39 is rotatably connected with the outer surface of the first fixing frame 11. The moving groove 37 is in communication with the inside of the movable hole 43, and the communication part has a size smaller than the diameter of the reel 39, so that the reel 39 is limited in the movable hole 43 and can only rotate in the movable hole 43. In one embodiment, one end of the movable hole 43 penetrates through the surface of the first fixing frame 11 and communicates with the outside, and the other end communicates with the moving groove 37 through a channel, which is built in the first fixing frame 11. The channel is for the traction strip 38 to pass through.

[0047] The other end of the traction strip 38 is connected with the outer surface of the same side of the reel 39, the reel 39 is provided with a plurality of limiting grooves 42, the plurality of limiting grooves 42 are arranged uniformly around the outer periphery of the reel 39, the sliding groove 40 is arranged above the movable hole 43 and on the outer surface of the first fixed frame 11, the sliding groove 40 is communicated with the movable hole 43, the limiting block 41 is slidably connected in the sliding groove 40, the limiting block 41 is matched with 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 with the sliding groove 40, the limiting block 41 is slid downward, the bottom end of the limiting block 41 is embedded into the limiting groove 42, the limiting groove 42 is clamped with the limiting block 41, and the reel 39 is fixed when the bottom end of the limiting block 41 is clamped with the limiting groove 42.

[0048] By adopting the above technical scheme, as the patient's arm gradually recovers, the movement intensity of the patient's arm also increases, and therefore the adjusting assembly is arranged, when the patient's arm elbow joint is stretched and bent and the locking rod 18 does not fix the pull rod 16, the second fixed frame 14 pulls the sliding rod 36 through the pull rod 16, so that the sliding rod 36 linearly slides in the moving groove 37, the sliding rod 36 pulls the traction strip 38 in the sliding process, and the sliding rod 36 needs to overcome the elastic force of the traction strip 38 in the movement process, so as to convert the elastic force of the traction strip 38 into the movement resistance of the patient's elbow joint, when the movement resistance needs to be increased, the operator moves the limiting block 41 upward in the sliding groove 40, so that the limiting block 41 is separated from the limiting groove 42 on the surface of the reel 39, and then the reel 39 is rotated by a certain angle, the reel 39 winds the traction strip 38 by a length in the rotating process, at this time, the traction strip 38 pulls the sliding rod 36 to move to the side close to the reel 39, and then the limiting block 41 is clamped into the limiting groove 42 under the action of gravity, at this time, the length of the traction strip 38 in the moving groove 37 is shortened, and when the patient's arm moves, the sliding rod 36 needs to overcome greater resistance when moving the traction strip 38, so as to increase the movement intensity of the patient's arm, and through the arrangement of the adjusting assembly, the movement intensity of the arm can be flexibly adjusted according to the recovery progress of the patient's arm, so as to match the clamping device with the recovery progress of the patient, and the convenience and functionality of the clamping device in the use process can be effectively improved.

[0049] As shown in Figure 1 and Figure 2 , the mounting hole 12 is arranged on the side wall of one side of the second fixed frame 14 and the side wall of one side of the first fixed frame 11, the tie 13 is arranged on the side wall of the other side of the second fixed frame 14 and the side wall of the other side of the first fixed frame 11, the tie 13 can pass through and extend through the mounting hole 12, and the surface of the tie 13 is provided with a magic tape, and the tie 13 can be fixed through the magic tape.

[0050] The inner surfaces of the two side walls of the first fixing frame 11 are provided with a plurality of through grooves 19, the extension direction of the through grooves 19 is the same as the length direction of the first fixing frame 11, a plurality of groups of through grooves 19 are arranged in an array, and the through grooves 19 on the two side walls are symmetrically distributed.

[0051] By adopting the above technical scheme, the strap 13 on the surface of the first fixing frame 11 and the second fixing frame 14 is used to bundle the clamping device outside the arm, the strap 13 passes through the mounting hole 12 on the surface of the first fixing frame 11 and the second fixing frame 14, so that the magic tape can be matched to realize the rapid wearing of the clamping device, in the bundling process, the through grooves 19 on the inner side of the first fixing frame 11 can make the first fixing frame 11 elastically deform by a certain amplitude, so that the first fixing frame 11 is more closely attached to the patient's arm, at the same time, the through grooves 19 and the air guide grooves 26 are helpful for the circulation of air, so that the heat dissipation effect of the clamping device can be further improved.

[0052] The working process of the technical scheme of the present application is as follows:

[0053] When the adjustable orthopedic rehabilitation clamping device clamps and resets the arm fracture site, the second fixing frame 14 is wrapped around the upper arm of the patient, and the first fixing frame 11 is placed on the lower side of the arm, the strap 13 passes through the mounting hole 12 on the surface of the first fixing frame 11 and the second fixing frame 14, so that the magic tape can be matched to realize the rapid wearing of the clamping device, when the piston rod 33 drives the piston plate 32 to move, the piston plate 32 will push the gas in the piston groove 31, at this time the gas in the piston groove 31 enters the gas storage cavity 27 in the air cushion 20 through the gas outlet pipe 30, the inflation of the air cushion 20 is realized by the injection of the gas, so that the gap between the patient's arm and the first fixing frame 11 can be reduced, the first fixing frame 11 cooperates with the second fixing frame 14 to extrude the elastic belt 15, at this time the gas in the elastic belt 15 will enter the air guide pipe 24 under the action of pressure, the gas is transported to the nozzle 25 through the air guide pipe 24, the gas ejected can flow between the patient's arm and the air cushion 20, so that part of the heat can be taken away by the gas flow, the patient's arm and the air cushion 20 are ventilated and cooled, the locking rod 18 is twisted to clampingly fix the pull rod 16 and the second fixing frame 14, so that the pull rod 16 and the second fixing frame 14 remain stable, the slide rod 36 pulls the traction strip 38 in the sliding process, the slide rod 36 needs to overcome the elastic force of the traction strip 38 in the movement process, so that the elastic force of the traction strip 38 can be converted into the movement resistance of the patient's elbow joint, so that the clamping device can be matched with the rehabilitation process of the patient.

[0054] In the scheme, by setting the compensation assembly, the clamping range of the clamping device can be flexibly adjusted according to the recovery speed and swelling condition of the patient, which not only ensures that the clamping device is always closely attached to the patient's arm, thereby guaranteeing the rehabilitation treatment effect of the patient's arm, but also has a good clamping and fixing effect on the arms of different patients, thereby improving the application range of the clamping device to a certain extent.

[0055] In the scheme, by setting the air guide assembly, the gas sprayed during the movement of the patient's arm can flow between the patient's arm and the air cushion, thereby taking away part of the heat through the gas flow, ventilating and cooling between the patient's arm and the air cushion, and maintaining the temperature of the contact part of the patient's arm and the air cushion within a proper range, which not only reduces the discomfort during long-term wearing of the clamping device, but also reduces the probability of infection and inflammation of the affected area due to overheating.

[0056] In the scheme, by setting the adjusting assembly, the length of the traction strip can be adjusted through the reel, and the movement intensity of the arm can be flexibly adjusted according to the rehabilitation progress of the patient's arm, so that the clamping device can be matched with the rehabilitation progress of the patient, thereby effectively improving the convenience and functionality of the clamping device during use.
