Description

Technical Field

[0001] The utility model relates to the technical field of bone splints, and specifically, to a splint for arm bones. Background Art

[0002] Bone splints are mainly used for closed fractures of the extremities, open fractures, those with relatively small wounds or whose wounds have healed after treatment. Old fractures suitable for closed reduction can also be treated with them. For fractures of the long bones of the lower extremities or some unstable fractures, other external fixation methods such as traction and brackets are often used in combination with splint fixation for patients with fractures.

[0003] In the prior art, for the utility model with the authorization announcement number: CN213372827U and the name: An Orthopedic Splint Device, when the arm is inserted between two splints corresponding to the fracture area, during the process of continuously tightening the screw by the nut, the spring is compressed. When the pressing strip presses towards the arm, through the sliding fit between the front and rear slide bars and the slide holes, the pressing strip will not shake when moving up and down. The soft contact with the arm skin through the soft layer makes the process of the arm being pressed by the pressing strip more comfortable. Until the pressing strip presses to an appropriate degree, at this time, the pressing strip presses the arm with high stability, and during actual operation, no support from the pressing strip is required.

[0004] In the prior art, for the utility model with the authorization announcement number: CN220495124U and the name: A Quick - Fixing and Breathable Splint for Pediatric Arm Fractures, through the cooperation of the winding roller and the torsion spring, according to the arm condition of the injured person, the length of the binding strap is adjusted to better fix the injured person. It is not only applicable to arms of various different specifications, but also can be reused, is convenient for installation and disassembly, and is flexible in use. When the splint is not in use, the torsion spring automatically drives the winding roller to recycle the binding strap, which will not cause messy placement and is convenient for continued use next time.

[0005] However, the splints in the above - mentioned devices are all of fixed length and cannot achieve the effect of telescopic length adjustment. Since the bone lengths of different patients are different, splints that are too long or too short are not conducive to treatment, resulting in certain limitations in the use of the above - mentioned devices.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 to 4 shown, this embodiment proposes a splint for arm bones, including a main splint 1 and an adjustment mechanism 2. The adjustment mechanism 2 includes a rotating rod 201 rotatably sleeved on the inner wall of the main splint 1, a planar gear 202 fixedly connected to the outer surface of the rotating rod 201, and two racks 203 meshing with the planar gear 202.

[0026] When the rotating rod 201 rotates, it will drive the planar gear 202 to rotate. When the planar gear 202 rotates, it will cause the two racks 203 to move closer to or away from each other.

[0027] One end of each of the two racks 203 is fixedly connected with a prefabricated plate 204, and the other ends of the two racks 203 are respectively sleeved in the inner walls of the two prefabricated plates 204. As Figure 3 and Figure 4 shown, one end of the rack 203 is fixedly connected to the outer surface of the corresponding prefabricated plate 204, and the other end of the rack 203 is slidably sleeved in the inner wall of the other prefabricated plate 204.

[0028] One side of each of the two prefabricated plates 204 facing away from each other is fixedly connected with a connecting rod 205. The outer surfaces of the two connecting rods 205 are respectively slidably connected to the inner walls on both sides of the main splint 1. One end of each of the two connecting rods 205 facing away from each other is fixedly connected with an auxiliary splint 206.

[0029] When the two racks 203 move closer to or away from each other, the two prefabricated plates 204 can be moved synchronously. Furthermore, the two auxiliary splints 206 can be made to move closer to or away from each other through the two connecting rods 205, thereby realizing the adjustment of the overall length of the device, enabling the arm fracture patient to be more comfortable when using it, and effectively avoiding the influence of the device being too long or too short on the fracture recovery effect.

[0030] Two guide rails 207 are fixedly connected to the inner wall of the main splint 1. The two sides of the two prefabricated plates 204 are respectively slidably sleeved on the outer surfaces of the two guide rails 207. By providing the guide rails 207, the two prefabricated plates 204 can move more stably.

[0031] The upper surface of the main splint 1 is fixedly connected with a first sponge pad 4, and the upper surfaces of the two auxiliary splints 206 are both fixedly connected with a second sponge pad 5. By providing the first sponge pad 4 and the second sponge pad 5, the comfort of the patient's arm can be improved, which is helpful for the patient's rehabilitation treatment.

[0032] The upper surface of the main splint 1 is provided with evenly distributed first ventilation openings 10, and both sides of the outer surface of the main splint 1 are provided with second ventilation openings 11. By providing the first ventilation openings 10 and the second ventilation openings 11, it can ensure that the main part of the device has a breathable effect when in use.

[0033] Embodiment 2

[0034] As Figures 1 to 4 shown, based on the same concept as in the above Embodiment 1, this embodiment also proposes that a limiting mechanism 3 is provided outside the rotating rod 201. The limiting mechanism 3 includes a worm gear 301 fixedly connected to the outer surface of the rotating rod 201. The worm gear 301 is located above the planar gear 202. By providing the worm gear 301, when the worm gear 301 rotates, it will drive the planar gear 202 to rotate through the rotating rod 201.

[0035] The inner wall of the main splint 1 is rotatably sleeved with a worm 302. The worm 302 meshes with the worm gear 301. The rotating shaft end of the worm 302 penetrates through the main splint 1 and is fixedly connected with a handle 303. By providing the handle 303, the contact area of the rotating shaft end of the worm 302 can be increased, which is convenient for rotating the worm 302.

[0036] When the handle 303 is rotated, it will drive the worm 302 to rotate. Then, through the rotation of the worm 302, the worm gear 301 will be rotated. When the worm gear 301 rotates, it will drive the planar gear 202 to rotate through the rotating rod 201. Moreover, the combination of the worm 302 and the worm gear 301 has the effects of deceleration and self-locking. In this way, the rotation of the rotating rod 201 and the planar gear 202 can be limited, avoiding the situation that the rotating rod 201 and the planar gear 202 rotate randomly, and facilitating the limitation of the positions of the two auxiliary splints 206.

[0037] Four first straps 6 and four second straps 7 are provided outside the main splint 1 and the two auxiliary splints 206. The four first straps 6 and the second straps 7 are respectively fixedly connected to the outer surfaces of the main splint 1 and the two auxiliary splints 206. By providing the first straps 6 and the second straps 7, it can be convenient to tie the device to the patient's arm, which is beneficial to the patient's recovery.

[0038] The outer surfaces of the first strap 6 and the second strap 7 are fixedly connected with a first Velcro 8 and a second Velcro 9 respectively. The first Velcro 8 and the second Velcro 9 are adapted to each other. By setting the first Velcro 8 and the second Velcro 9, the work of bonding and fixing the first strap 6 and the second strap 7 can be facilitated, so as to facilitate the fixing of the device on the patient's arm.

[0039] Working principle: When using the device, adjust the length of the device according to the length of the patient's arm bone. This can be achieved by turning the handle 303. When the handle 303 is turned, the worm 302 will rotate. When the worm 302 rotates, the worm gear 301 can be rotated. By the rotation of the worm gear 301, the rotating rod 201 and the planar gear 202 can be rotated. When the planar gear 202 rotates, the two racks 203 will move closer to or away from each other. In this way, through the precast slab 204 and the connecting rod 205, the two auxiliary splints 206 can move closer to or away from each other, so as to adjust the overall length of the device to meet the usage requirements of different patients with arm fractures, optimize the usage effect of the device. After the length of the device is adjusted, the patient's arm can be placed on the first sponge pad 4 and the second sponge pad 5, and then the four groups of the first straps 6 and the second straps 7 are tied around the patient's arm. Finally, the four groups of the first Velcro 8 and the second Velcro 9 are used for the bonding work of the first strap 6 and the second strap 7, so as to conveniently fix the device on the patient's arm.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
