For example, the length and shape of traditional splints are often fixed, and it is difficult to accurately adjust them according to the specific conditions of the patient, which to a certain extent limits their scope of application and fixation effect. Therefore, a new limb splint is urgently needed to solve the above technical problems. Summary of the invention

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.

[0021] With the development of modern medical technology, traditional limb splints can no longer meet clinical needs. For example, the length and shape of traditional splints are often fixed, and it is difficult to accurately adjust them according to the specific conditions of the patient, which to some extent limits their scope of application and fixation effect.

[0022] In order to solve the above technical problems, the present invention provides a combined limb splint for traditional Chinese medicine orthopedics, comprising at least three arc-shaped plates 1, a connecting rod 2, a spring 3 and a strap 4, a first groove 101 and a second groove 102 are provided on the side of the arc-shaped plate 1, the second groove 102 is provided in the first groove 101, and the inner diameter of the second groove 102 is smaller than the inner diameter of the first groove 101, and the limb splint also includes: The connecting rod 2 includes a first connecting rod 201 and a second connecting rod 202. The second connecting rod 202 is arranged at both ends of the first connecting rod 201. The first connecting rod 201 extends to the first groove 101 of the arc plate 1, and the second connecting rod 202 extends to the second groove 102; one end of the spring 3 is connected to the inner side of the first groove 101, and the other end is connected to the first connecting rod 201. The free length of the spring 3 is smaller than the depth of the first groove 101. The multiple arc plates 1 are connected in sequence into a cylindrical structure through the connecting rod 2; the belt 4 contacts the outer surfaces of the multiple arc plates 1, and is used to control the size of the cylindrical structure formed by the multiple arc plates 1 through a stretching action.

[0023] During specific implementation: the limb is inserted into the combined limb splint, and the strap 4 is pulled to compress the arc plate 1 of the limb splint. The compressed arc plate 1 can be used to fix the limb splint to the outside of the limb, thereby fixing the fracture site of the limb.

[0024] Through the above technical scheme and specific implementation process, it can be known that after the plurality of arc-shaped plates 1 are connected in sequence by the connecting rod 2, the opening and closing size of the limb splint can be controlled by the strap 4. Since the opening and closing size of the limb splint can be changed according to the limb conditions of the user, the limb splint of the present invention has a large application range. During the use of the limb splint, the clamping force of the limb splint can be adjusted according to the strap 4, while ensuring stable fixation of the limbs, it avoids problems such as too tight causing discomfort to the user, or too loose causing failure of fixation of the limbs. The present invention provides a first groove 101 and a second groove 102 connected in sequence on the side of the arc plate 1, and connects multiple arc plates 1 by combining a connecting rod 2 and a spring 3, so that the limb splint can maintain good stability during the opening and closing process, and after the arc plates 1 of the limb splint are compressed, the strap 4 is released to restore the cylindrical structure composed of the arc plates 1 to its original size; by connecting one end of the spring 3 to the inner side of the first groove 101 and the other end to the first connecting rod 201, a buffering effect can be provided when the limb splint is subjected to external force, thereby reducing the user's discomfort.

[0025] As a possible implementation mode, in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, a limiting ring 103 is provided on the outer surface of the arc plate 1; one end of the strap 4 is fixed to the outer surface of any arc plate 1, and the other end passes through the limiting rings 103 on the outer surfaces of the remaining arc plates 1 in sequence, and is fixed to the limiting rings 103 on the outer surface of the arc plate 1.

[0026] By adopting the above technical solution, the present invention can limit the strap 4 to a fixed position on the outer surface of the curved plate 1 by setting a limiting ring 103 on the outer surface of the curved plate 1, thereby preventing the strap 4 from slipping or dislocating. At the same time, the limiting ring 103 can evenly distribute the tension of the strap 4 on the curved plate 1, thereby improving the overall stability of the limb splint of the present invention. For example, the strap 4 can be an elastic belt, which has good elasticity and elasticity. When used, it can be adaptively adjusted according to the shape and size of the user's limbs. In other words, whether it is thinner or thicker limbs, the elastic belt can provide just the right fixing force, which will not be too tight to cause poor blood circulation in the user, nor too loose to affect the fixing effect of the limb splint.

[0027] As a possible implementation mode, in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, the inner surface of the arc plate 1 is provided with a third groove 104 extending to the side of the arc plate 1, and the limb splint also includes a gas support mechanism 5; the gas support mechanism 5 is provided with a connecting surface 5011 and a supporting surface 5012, the connecting surface 5011 is provided with a protrusion 5013 matching the third groove 104, and the gas support mechanism 5 is arranged on the inner surface of the arc plate 1 through the connecting surface 5011; the gas support mechanism 5 deforms the supporting surface 5012 through compressed air.

[0028] By adopting the above technical solution, the user's limbs are inserted into the combined limb splint, and the strap 4 is pulled, so that the arc plate 1 in the limb splint is compressed, and the gas support mechanism 5 deforms the support surface 5012 through compressed air, so that the support surface 5012 contacts the user's limbs, thereby fixing the limb fracture site. The support surface 5012 can contact the user's skin or soft tissue, thereby playing a role in buffering or dispersing pressure. Compared with directly using the arc plate 1 for support, the support surface 5012 can reduce the friction and pressure of the limb splint on the user's skin, thereby improving the user's comfort. Furthermore, the gas support mechanism 5 can control the support strength of the support surface 5012 and the limbs by adjusting the gas pressure, which can adapt to different usage requirements.

[0029] As a possible implementation mode, in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, the gas support mechanism 5 includes a compression chamber 501 and a push rod 502, the compression chamber 501 includes a connecting surface 5011 and a supporting surface 5012, the connecting surface 5011 is connected to the third groove 104; the side surfaces of the compression chamber 501 are respectively provided with a first slide plate 5014 and a second slide plate 5015; the first slide plate 5014 and the second slide plate 5015 can slide along the inner wall of the compression chamber 501; one end of the push rod 502 is connected to the first slide plate 5014 of any compression chamber 501, and the other end is connected to the second slide plate 5015 of another compression chamber 501.

[0030] By adopting the above technical solution, the user's limbs are inserted into the combined limb splint, and the strap 4 is pulled, so that the arc plate 1 in the limb splint is compressed, and the push rod 502 connected to the first slide plate 5014 and the second slide plate 5015 on both sides of the compression chamber 501 pushes the first slide plate 5014 and the second slide plate 5015 to slide along the inner wall of the compression chamber 501 at the same time, compressing the air in the compression chamber 501, so that the support surface 5012 of the compression chamber 501 is deformed by force to bulge 5013, and contacts with the limbs, thereby fixing the limb fracture site. In the gas support mechanism 5 of the present invention, the setting of the push rod 502 enables the gas support mechanism 5 to realize linkage between multiple arc plates 1. When one end of the push rod 502 pushes the first slide plate 5014 of the compression chamber 501 of any arc plate 1 to move, the other end of the push rod 502 simultaneously pushes the second slide plate 5015 of the compression chamber 501 of another arc plate 1 to move, thereby realizing the coordinated work of the entire limb splint.

[0031] Furthermore, the gas support mechanism 5 adjusts the support force of the support surface 5012 by controlling the gas pressure in the compression chamber 501. The limb splint of the present invention has little vibration during the process of adjusting the gas pressure in the compression chamber 501 and has good stability.

[0032] As a possible implementation mode, in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, the gas support mechanism 5 also includes a first slider 503 and a second slider 504; the first slider 503 and the second slider 504 are both provided with through holes; the third groove 104 is provided with a first slider 503 on the side close to the first slider 5014, and a second slider 504 on the side close to the second slider 5015; one end of the push rod 502 is connected to the first slider 5014 of any compression chamber 501 through the through hole of the first slider 503, and the other end is connected to the second slider 5015 of another compression chamber 501 through the through hole of the second slider 504.

[0033] By adopting the above technical solution, the user's limbs are inserted into the combined limb splint, and the strap 4 is pulled, so that the arc plate 1 in the limb splint is compressed, and the through holes of the first slider 503 and the second slider 504 on both sides of the gas support mechanism 5 push the first slide plate 5014 and the first slide plate 5014 to move, so that the air in the compression chamber 501 is compressed, and the support surface 5012 of the compression chamber 501 is deformed by force to form a protrusion 5013 and contact the limb, thereby fixing the fracture site of the limb.

[0034] In the above technical scheme, since the third groove 104 is provided with the first slider 503 and the second slider 504, and one end of the push rod 502 passes through the through hole of the first slider 503 on any curved plate 1 and is connected to the first slide plate 5014, and the other end passes through the through hole of the second slider 504 on the other curved plate 1 and is connected to the second slide plate 5015, under the limiting action of the first slider 503 and the second slider 504, the push rod 502 can be stably moved toward the first slide plate 5014 or the second slide plate 5015. That is to say, by arranging the first slider 503 and the second slider 504 in the third groove 104, the push rod 502 can be prevented from being offset during the movement, thereby improving the stability of the limb splint.

[0035] It should be noted that, in this embodiment, the first slider 503 and the second slider 504 can also be used to control the pressure of the compression chamber 501 within a reasonable range, that is, the moving length of the push rod 502 can be controlled by the limiting effect of the first slider 503 and the second slider 504. Specifically, the first slider 503 and the second slider 504 can be fixedly connected to the push rod 502, and the extension length of the push rod 502 in the compression chamber 501 during the process of pushing the first slide plate 5014 or the second slide plate 5015 is set to be certain. When the push rod 502 drives the first slider 503 or the second slide plate 504 to slide, the first slider 503 or the second slide plate 504 slides to one end of the compression chamber 501 and abuts against the compression chamber 501, which can prevent the push rod 502 from further extending into the compression chamber 501, thereby controlling the pressure in the compression chamber 501 within a reasonable range, that is, the deformation of the support surface 5012 of the compression chamber 501 can be controlled within a reasonable range, thereby improving the comfort of the user.

[0036] As a possible implementation mode, in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, the push rod 502 includes a first push rod 5021 and a second push rod 5022, and the through hole includes a first through hole and a second through hole that are connected; the first push rod 5021 extends to the first through hole, and the second push rod 5022 extends to the second through hole and is connected to the first push rod 5021; the second push rod 5022 at one end of the first push rod 5021 is connected to the first slide plate 5014 of any compression bin 501, and the second push rod 5022 at the other end is connected to the second slide plate 5015 of another compression bin 501.

[0037] With the above technical solution, the above combined limb splint requires the push rod 502 to have a certain support strength and deformation capacity during compression or release to match the size of the cylindrical structure formed by the arc plate 1. In the limb splint of the present invention, the push rod 502 is set as a first push rod 5021 and a second push rod 5022, the first push rod 5021 mainly provides support strength, and the second push rod 5022 can have a strong deformation capacity, so that the limb splint can maintain good stability during use. For example, in another embodiment, the outer diameter of the first push rod 5021 is greater than the outer diameter of the second push rod 5022; the inner diameter of the first through hole is greater than the inner diameter of the second through hole; in another embodiment, the outer diameter of the first push rod 5021 is greater than the outer diameter of the second push rod 5022; the inner diameter of the first through hole is greater than the inner diameter of the second through hole, and the inner diameter of the first through hole matches the outer diameter of the first push rod 5021, and the inner diameter of the second through hole matches the outer diameter of the second push rod 5022.

[0038] As a possible implementation mode, the combined limb splint for traditional Chinese medicine orthopedics of the present invention also includes a support belt 6; one end of the support belt 6 is connected to the first slider 503, and the other end is connected to the second slider 504. Under the action of the belt 4, the multiple arc plates 1 can make the support belt 6 abut against the support surface 5012 of the compression chamber 501.

[0039] By adopting the above technical scheme, the limb is inserted into the combined limb splint, and the strap 4 is pulled, the arc plate 1 in the limb splint is compressed, and the push rods 502 on both sides of the gas support mechanism 5 push the first slide plate 5014 and the second slide plate 5015 to compress the air in the compression chamber 501, so that the support surface 5012 of the compression chamber 501 is deformed and then abuts against the support belt 6. The support surface 5012 can further push the support belt 6 to make the support belt 6 contact with the limb, so that the fracture site of the limb is fixed with the support belt 6. In this embodiment, since the push rod 502 is fixedly connected to the first slider 503 or the second slider 504, when the strap 4 is pulled, the push rods 502 on both sides of the compression chamber 501 drive the first slider 503 and the second slider 504 to slide along the third groove 104 toward the compression chamber 501. Since one end of the support belt 6 is connected to the first slider 503 and the other end is connected to the second slider 504, during this process, the support belt 6 is further stretched or relaxed. For this reason, the support surface 5012 can push the support belt 6 so that the support belt 6 is in full contact with the outer surface of the limb. Compared with directly using the support surface 5012 to support the limb, the supporting effect of the support belt 6 is more stable and the pressure is more uniform, which can further improve the user's comfort.

[0040] As a possible implementation mode, in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, the support surface 5012 and the support belt 6 are made of elastic materials. By adopting the above technical scheme, the use of flexible materials can ensure that the support belt 6 or the support surface 5012 can fully contact the limbs, provide a certain elastic force, and uniformly apply force on the limbs, effectively reducing the friction or compression of the existing limb splints on the limbs, and improving the comfort of the user. Furthermore, under normal circumstances, after using the limb splint, the user also needs to perform appropriate rehabilitation training or daily activities, which requires the limb splint and related components to have a certain flexibility. The flexible material has good elasticity and ductility, and can adapt to the user's limb activity needs.

[0041] It should be noted that in the combined limb splint for traditional Chinese medicine orthopedics of the present invention, multiple push rods 502 and / or connecting rods 2, as well as multiple support belts 6 can be provided to achieve the best fixation effect of the limb splint on the user's limbs. The specific number of push rods 502 and / or connecting rods 2, and support belts 6 used can be set according to actual usage requirements.

[0042] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0043] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
