Abstract
Description
Technical Field
[0001] This invention relates to the field of orthopedic reduction and support devices, specifically to a reduction and support device that facilitates fixation of fracture sites. Background Technology
[0002] A fracture reduction and support device is a medical device used in fracture treatment. It aims to help reduce the fracture site and maintain its stability through external force, thereby promoting fracture healing. These devices typically combine mechanical principles with ergonomic design to accommodate fractures of different locations and types. By providing stable fixation, they reduce micromovements at the fracture site, creating a favorable biomechanical environment for fracture healing.
[0003] In existing technologies, devices for arm fracture reduction and support typically employ multiple fixation straps to secure the device to the fracture site, ensuring a stable fit. While this achieves good fixation, the process requires sequential adjustment of the straps, tightening and loosening them one by one. This is time-consuming and can lead to uneven pressure due to improper strap placement, increasing the risk of skin compression at the fracture site. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a reduction and support device that facilitates fixation of fracture sites.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reduction and support device for facilitating fixation of fractured areas includes two connecting plates. Two rotating blocks are mounted on the outer walls of the adjacent sides of the two connecting plates. The ends of the rotating blocks away from the connecting plates are connected to mounting plates via two first electric telescopic rods. The opposite sides of the mounting plates are connected to connecting seats via two bolts. A rotating plate is located on the opposite side of the two connecting seats. The rotating plates are driven to rotate by a first driving mechanism internally located on each of the two connecting seats. Two housings are located on the opposite side of the two rotating plates. An airbag for close contact with the arm is located inside each of the two housings. A second driving mechanism for moving the airbag is located inside each of the two housings.
[0006] Optionally, the first drive mechanism includes a protective box installed on the outer wall of the connecting seat, a drive motor installed inside the protective box, and the output end of the drive motor extending into the connecting seat and connected to a gear.
[0007] Optionally, the rotating plate has a rotating end on the outer wall near the mounting plate, which is rotatably connected to the connecting seat. A gear ring is installed on the outer wall away from the rotating frame, and the gear ring meshes with the gear.
[0008] Optionally, two fixed plates are installed on the outer wall of the rotating plate away from the rotating seat. A double-ended screw is rotatably installed inside each of the two fixed plates. Two sliding blocks are threadedly installed on the outer wall of each of the two double-ended screws. Both housings are connected to the two sliding blocks that are close to each other.
[0009] Optionally, the second drive mechanism includes two rectangular slots opened on the outer wall of the housing. Movable blocks are slidably installed inside the two rectangular slots. A ring is installed at one end of the two movable blocks that are close to each other. The airbag is bonded to the hook side of the ring by the hook side of the hook and loop fastener provided on the inner wall of the ring through the hook and loop fastener provided on the outer wall.
[0010] Optionally, both of the movable blocks have through holes inside, and the outer wall of the airbag is equipped with two connectors that plug into the through holes. The ends of the two movable blocks that are far apart are provided with rubber plugs for sealing the through holes.
[0011] Optionally, the inner walls on both sides of the two rectangular grooves are provided with sliding grooves, and sliders are installed inside the two sliding grooves. The ends of the two sliders away from the sliding grooves are connected to the moving block.
[0012] Optionally, a protrusion is installed on one side of the outer wall of each of the two movable blocks, and a second electric telescopic rod is installed inside the two protrusions. An arc-shaped clamp is installed at the telescopic end of each of the two second electric telescopic rods, and multiple drainage holes are opened on the outer wall of the side of the two arc-shaped clamps that are close to each other.
[0013] Optionally, arc-shaped rods are rotatably mounted on both outer walls of the two movable blocks, and soft pads are adhered to the outer wall of the two arc-shaped rods on the side closest to the housing.
[0014] Optionally, the airbag is made of rubber material, and the inner wall of the airbag is provided with multiple protrusions.
[0015] The beneficial effects of this invention are: 1. In this invention, by setting two arc-shaped clamps inside the shell, after the shell is fitted onto the surface of the arm, the two arc-shaped clamps move toward each other and abut against the arm, achieving the effect of initially and quickly installing the shell at both ends of the fracture site of the arm; in conjunction with the inflation of the airbag, the stability between the shell and the arm can be further improved, the entire installation speed of the device is relatively fast, and the pressure between the airbag and the surface of the arm is uniform, so as not to cause secondary damage to the fracture site of the arm.
[0016] 2. In this invention, if the user is allergic to the rubber airbag, a cotton towel can be placed inside the two shells, with both ends of the cotton towel protruding from the opposite ends of the two shells. At this time, multiple arc-shaped rods on the outside of the two shells can be used to press and fix the ends of the cotton towel, ensuring that the position of the cotton towel inside the two shells is limited and fixed, making it convenient to subsequently put the shell on the surface of the arm. This allows users who are allergic to rubber to quickly use the device to limit and fix the fracture site of the arm.
[0017] 3. In this invention, after the device is fitted onto the surface of the upper arm or forearm, the airbags inside both shells are inflated. To facilitate rapid reduction of swelling at the fracture site, the tubing inside the two through holes can be removed, and the slider can be moved within the corresponding groove. This allows the airbags inside the two shells to cover the surface of the fracture site. Prepared ice water is then injected into the airbags through the two through holes. The two airbags in contact with the fracture site, combined with the injected ice water, can provide a cold compress to the swelling, reducing swelling, relieving pain, and alleviating local inflammation. If the user does not have prepared ice water, chilled beverages can be injected into the airbags through the through holes for rapid cold compress treatment of the fracture site. This avoids the problem of using chilled beverage bottles directly on the fracture site, which results in a smaller cold compress area and poorer cold compress effect.
[0018] 4. In this invention, when the device is fitted onto the fractured surface of the arm, the disinfectant solution is delivered to the inside of the arc-shaped splint through a pipe via an external drainage device, and discharged to the surface of the arm through multiple drainage holes. The two arc-shaped splints and airbags inside the two shells are controlled to release the tight contact between them and the arm, ensuring that they only slightly contact the surface of the arm. With the help of two double-headed screws, the two shells move back and forth on the surface of the arm, and the first drive mechanism drives the rotating plate and the two shells to rotate on the surface of the arm. This allows the multiple drainage holes on the outer wall of the two arc-shaped splints on the side closest to each other to evenly discharge the disinfectant solution to the surface of the arm, facilitating automatic cleaning and disinfection of the arm surface.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Reference Figures 1-9A reduction and support device for facilitating fixation of fractured parts includes two connecting plates 1. Two rotating blocks 12 are installed on the outer wall of the two connecting plates 1 on their adjacent sides. The ends of the two rotating blocks 12 away from the connecting plates 1 are connected to mounting plates 2 by two first electric telescopic rods 13. The sides of the two mounting plates 2 away from each other are threadedly connected to connecting seats 3 by two bolts 15. A rotating plate 4 is provided on the sides of the two connecting seats 3 away from each other. The two connecting seats 3 drive the rotating plates 4 to rotate through a first driving mechanism provided inside. Two housings 6 are provided on the sides of the two rotating plates 4 away from each other. An airbag 11 for close contact with the arm is provided inside the two housings 6. A second driving mechanism for moving the airbag 11 is provided inside the two housings 6. Two rotating blocks 12 are arranged close to the outer wall of the two connecting plates 1. Two of them are rotatably connected to the connecting plates 1, and the other two are fixedly connected to the connecting plates 1. A driving device is preset inside the two rotating blocks 12. The output end of the two driving devices is connected to the rotating part of the two rotating blocks 12, so that the two driving devices can drive the two connecting plates 1 and the other two rotating blocks 12 to rotate and adjust.
[0024] As a technical optimization of the present invention, the first driving mechanism includes a protective box 14 installed on the outer wall of the connecting seat 3. A drive motor 17 is installed inside the protective box 14, and the output end of the drive motor 17 extends into the connecting seat 3 and is connected to a gear 18. After starting, the drive motor 17 can drive the gear 18 to rotate synchronously inside the connecting seat 3.
[0025] As a technical optimization of the present invention, a rotating end 20 is provided on the outer wall of the rotating plate 4 near the mounting plate 2. The rotating end 20 is rotatably connected to the connecting seat 3. A gear ring 19 is installed on the outer wall of the rotating end 20 away from the rotating frame. The gear ring 19 meshes with the gear 18. Because the gear 18 meshes with the gear ring 19, the gear 18 can drive the gear ring 19, the rotating end 20 and the rotating plate 4 to rotate together during the rotation process.
[0026] As a technical optimization of the present invention, two fixed plates 5 are installed on the outer wall of the rotating plate 4 away from the rotating seat. A double-ended screw 21 is rotatably installed inside each of the two fixed plates 5. Two sliding blocks 22 are threaded onto the outer walls of each of the two double-ended screws 21. Each of the two housings 6 is connected to its adjacent sliding blocks 22. A first driving device is pre-installed on the outer wall of each of the two fixed plates 5. The output ends of the two first driving devices are respectively connected to one end of each of the two double-ended screws 21, thereby driving the two double-ended screws 21 to rotate inside the corresponding fixed plate 5, which in turn drives the two sliding blocks 22 on their outer walls to move towards or away from each other. This synchronously drives the two housings 6 to move and adjust synchronously with the movement of the sliding blocks 22 on their outer walls.
[0027] As a technical optimization of the present invention, the second driving mechanism includes two rectangular slots 16 formed on the outer wall of the housing 6. Movable blocks 7 are slidably installed inside each of the two rectangular slots 16. A circular ring 24 is installed at one end of each movable block 7 that is close to the other. The airbag 11 is bonded to the hook-and-loop fastener on the inner wall of the circular ring 24 via a Velcro hook-and-loop fastener 29 on the outer wall. The connection between the airbag 11 and the circular ring 24 via Velcro facilitates flexible assembly and disassembly of the airbag 11, making it easy to replace and clean.
[0028] As a technical optimization of the present invention, each of the two movable blocks 7 has a through hole 26 inside. Two connecting nozzles 30, which are inserted into the through holes 26, are installed on the outer wall of the airbag 11. Rubber plugs 27 for sealing the through holes 26 are provided at the ends of the two movable blocks 7 that are far apart. When the airbag 11 is installed on the inner wall of the ring 24, its two external connecting nozzles 30 need to be inserted into the corresponding through holes 26 so that the subsequent external pre-installed inflation hose can be inserted into the through holes 26 to inflate the airbag 11.
[0029] As a technical optimization of the present invention, each of the two rectangular grooves 16 has a sliding groove 23 on its inner side. A slider 25 is installed inside each of the two sliding grooves 23, and the end of each slider 25 away from the sliding groove 23 is connected to a moving block 7. A linear motor is pre-installed inside each of the two sliding grooves 23. The two linear motors can drive the two sliders 25 to move within their respective sliding grooves 23, thereby causing the corresponding moving block 7 to move and adjust within the rectangular grooves 16.
[0030] As a technical optimization of the present invention, protrusions are installed on one side of the outer wall of each of the two movable blocks 7, and second electric telescopic rods 9 are installed inside the two protrusions. Arc-shaped clamps 10 are installed at the telescopic ends of the two second electric telescopic rods 9, and multiple drainage holes 31 are opened on the outer wall of the two arc-shaped clamps 10 that are close to each other. When the telescopic ends of the two second electric telescopic rods 9 extend together, they can drive the two arc-shaped clamps 10 to move in the direction of approach, clamping and fixing the user's arm, which facilitates the quick fixing of the housing 6 to the surface of the arm. The interior of the two arc-shaped clamps 10 is hollow, and the two arc-shaped clamps 10 are connected to the external pre-set drainage device through the connecting pipe, so that the external disinfectant solution can enter the interior of the arc-shaped clamps 10 through the pipe and be discharged to the surface of the arm through the multiple drainage holes 31, which facilitates the cleaning and disinfection of the arm surface.
[0031] As a technical optimization of the present invention, arc-shaped rods 8 are rotatably mounted on both outer walls of the two movable blocks 7, and soft pads are adhered to the outer wall of the two arc-shaped rods 8 near the housing 6. Two second driving devices are preset on one outer wall of each of the two movable blocks 7, and the output ends of the two second driving devices are respectively connected to the rotating parts of one end of the two arc-shaped rods 8, thereby enabling the two arc-shaped rods 8 to rotate and adjust on both outer walls of the movable blocks 7.
[0032] As a technical optimization of the present invention, the airbag 11 is made of rubber material, and the inner wall of the airbag 11 is provided with a plurality of protrusions 28. After the airbag 11 is inflated, the protrusions 28 on its inner wall can abut against the arm. As the slider 25 moves together with the two moving blocks 7 and the ring 24 inside the slide groove 23, the airbag 11 is moved and adjusted inside the housing 6, so that it can massage the arm with the help of the plurality of protrusions 28 that abut against the arm.
[0033] In this invention, when the user uses the device, the connecting seat 3 and the mounting plate 2 are connected by two bolts 15, so that both connecting seats 2 can be separated from the corresponding mounting plates 2. When the radius or humerus of the user's arm is fractured, one of the connecting seats 3, the rotating plate 4 and the two housings 6 can be directly fitted onto the surface of the user's forearm or upper arm where the fracture occurs. The two double-headed screws 21 are controlled to rotate together, which increases the distance between the two housings 6, so that the two housings 6 are located at the two ends of the fracture site. Then, the telescopic ends of multiple second electric telescopic rods 9 are controlled to extend together, which moves the corresponding two arc-shaped clamps 10 toward the same direction and abuts against the arm, achieving the initial effect of quickly installing the two housings 6 at both ends of the arm fracture site.
[0034] Subsequently, the externally preset inflation device can be activated to inflate the air bladders 11 inside the two shells 6. After inflation, the two air bladders 11 can fit tightly against the arm, further fixing the two shells 6 to both ends of the arm fracture site. By effectively limiting and fixing both ends of the arm fracture site, the movement of the arm fracture site can be restricted, keeping the fracture ends relatively still and creating favorable conditions for fracture healing. At the same time, stable fixation can alleviate pain to a certain extent, making the patient feel more comfortable. Moreover, effective fixation helps to facilitate subsequent treatment, such as wound treatment and patient transportation, and also lays the foundation for subsequent rehabilitation training, avoiding the impact of arm rehabilitation progress due to instability of the fracture ends.
[0035] If the user's elbow joint is fractured, then it can be treated as follows: Figure 1 and Figure 2 The state shown will Figure 1The entire device is fitted onto the surface of the user's arm, with two housings 6 located on the upper arm and two other housings 6 located on the forearm. The steps of fixing the housings 6 can then be repeated. With the help of the corresponding arc-shaped splint 10 and airbag 11, multiple housings 6 can be fixed at different positions on the surface of the arm, and can limit and fix the elbow joint that has fractured, which facilitates subsequent treatment of the elbow joint.
[0036] If the user is allergic to the rubber airbag 11, a cotton towel can be placed inside the two housings 6, unfolded into a circle and pressed against the inner wall of the airbag 11, with both ends of the cotton towel protruding from the opposite ends of the two housings 6. At this time, multiple curved rods 8 can be controlled to rotate away from the housings 6, and the protruding ends of the cotton towel can be folded over to press against the outer wall of the housing 6. Finally, multiple curved rods 8 can be controlled to rotate back towards the housings 6, thus pressing and fixing the ends of the cotton towel, ensuring that the position of the cotton towel inside the two housings 6 is limited and fixed, making it convenient to subsequently put the housings 6 on the surface of the arm. This allows users with rubber allergies to quickly use the device to limit and fix the fractured part of the arm.
[0037] Furthermore, after the device is fitted onto the surface of the upper arm or forearm, the airbags 11 inside the two housings 6 are inflated. To facilitate rapid reduction of swelling at the fracture site, the tubing inside the two through holes 26 can be removed, allowing some of the gas inside the airbags 11 to escape from the through holes 26. This causes the airbags 11 to no longer be in close contact with the arm, and the telescopic ends of the multiple second electric telescopic rods 9 are retracted a certain distance, causing the arc-shaped splint 10 to also no longer be in close contact with the arm. By controlling the slider 25 to move within the corresponding groove 23, the airbags 11 and the arc-shaped splint 10 inside the two housings 6 can move towards each other until the near ends of the two airbags 11 are removed from the corresponding housings 6 and placed on the surface of the fracture site. Then, the telescopic ends of the multiple second electric telescopic rods 9 are extended again, causing the arc-shaped splint 10 to re-attach to the fracture site. The two ends of the fracture site are joined together, and prepared ice water is injected into the airbag 11 through two through holes 26. The two through holes 26 are then sealed with two rubber stoppers 27. This allows the two airbags 11, which are in contact with the surface of the fracture site, to apply a cold compress to the swelling caused by the fracture site, thereby reducing swelling, relieving pain, and alleviating local inflammation. The low temperature causes vasoconstriction, reducing tissue fluid leakage and bleeding, and decreasing nerve sensitivity, thus helping to control acute injury symptoms and creating favorable conditions for subsequent treatment of the fracture site. If the user does not have ice water prepared in advance, refrigerated beverages can also be injected into the airbags 11 through the through holes 26 to quickly apply a cold compress to the fracture site. This avoids the problem of using refrigerated beverage bottles directly to apply a cold compress to the fracture site, which may result in a smaller cold compress area and poorer cold compress effect.
[0038] Meanwhile, after a period of treatment for the elbow joint, once the plaster cast or other fixation devices are removed, the device can be reapplied to the arm. Figure 2 As shown, controlling the two connecting plates 1 to drive the other mounting plate 3 and the housing 6 to slowly rotate upward and downward can drive the forearm to perform up-and-down movement exercises, which is beneficial to the recovery of the elbow joint.
[0039] Moreover, since the rotating plate 4 and the connecting seat 3 can be driven to rotate by the first drive mechanism, the drive motor 17 near the forearm can be controlled to drive the gear 18 to rotate, which in turn drives the rotating plate 4 and the two housings 6 and other components to rotate repeatedly in both directions, thus synchronously driving the forearm to perform rotational exercises, ensuring that the elbow joint can quickly return to its normal state.
[0040] When the device is applied to the fractured surface of the arm, the arm surface needs to be cleaned and disinfected regularly. At this time, the disinfectant solution can be delivered to the inside of the arc-shaped splint 10 through the external drainage device and discharged to the arm surface through multiple drainage holes 31. The two arc-shaped splints 10 and the airbag 11 inside the two housings 6 are released from their tight contact with the arm, ensuring that they are only slightly in contact with the arm surface. With the help of two double-headed screws 21, the two housings 6 move back and forth on the arm surface, and the first drive mechanism drives the rotating plate 4 and the two housings 6 to rotate on the arm surface. This allows the multiple drainage holes 31 on the outer wall of the two arc-shaped splints 10 that are close to each other to evenly discharge the disinfectant solution to the arm surface, which facilitates automatic cleaning and disinfection of the arm surface.
[0041] Meanwhile, since the inner wall of the airbag 11 is provided with multiple protrusions 28, and after the airbag 11 is inflated, the multiple protrusions 28 can abut against the arm, controlling the two arc-shaped clamps 10 inside the two shells 6 and the airbag 11 to release the tight abutment state between them and the arm, ensuring that they only slightly abut against the surface of the arm. With the rotation of the two double-headed screws 21, the two shells 6 and the airbag 11 inside them can move back and forth on the surface of the arm, so that the multiple protrusions 28 on the inner wall of the airbag 11 have a horizontal back and forth massage effect on the arm. While the two double-headed screws 21 drive the two housings 6 to move back and forth on the surface of the arm, the corresponding drive motor 17 can also drive the gear 18 and gear ring 19 to rotate synchronously, so that the rotating plate 4 and the two housings 6 can rotate on the surface of the arm, driving the two airbags 11 to massage the fractured part of the arm in rotation, achieving a comprehensive massage effect on the fractured part of the arm, promoting blood circulation in the fractured part of the arm, relieving muscle tension, maintaining joint flexibility and reducing pressure, which is conducive to the rapid recovery of the fractured part of the arm.
[0042] While massaging the fractured arm area using the two reciprocating shells 6 and airbags 11, the above-mentioned steps of applying cold compresses to the fractured arm area can be repeated. Hot water at a specified temperature is injected into the airbags 11 through the through-holes 26, so that the airbags 11, in conjunction with the hot water injected inside, can provide heat treatment to the fractured arm area, which can promote blood circulation in the arm during the recovery period, relieve muscle stiffness and limited joint movement, and reduce chronic pain and discomfort.
[0043] After applying cold or hot compresses to the fractured part of the user's arm using the airbag 11 inside the housing 6, the device is removed from the surface of the arm. Then, the rubber stopper 27 is removed from the outside of the through hole 26. The airbag 11 is manually squeezed to allow the liquid injected inside to be discharged outward from the two through holes 26. After manually squeezing the airbag 11, a small amount of liquid that has not been automatically discharged still remains inside the airbag 11. At this time, plastic bags can be placed on the surfaces of the two housings 6 and inverted so that the connecting seat 3 is located outside the plastic bag. The first drive mechanism drives the rotating plate 4 and the two housings 6 to rotate synchronously, so that the two housings 6 rotating inside the plastic bag can throw the liquid remaining inside the two airbags 11 outward into the plastic bag, avoiding the problem of some liquid remaining inside the airbag 11 and affecting the subsequent use of the airbag 11.
[0044] Multiple arc-shaped rods 8 set on the outside of the housing 6 can be controlled to rotate together away from the housing 6 when the device is fitted onto the surface of the forearm. This allows the arc-shaped rods 8 that have rotated away from the housing 6 to serve as a support frame for the device and the arm, making it convenient for the user to place the arm on a low table or workbench, facilitating medical staff to perform relevant examinations on the arm. Furthermore, when the device is not in use, the lower arc rod 8 can be controlled to rotate away from the housing 6, and the lower arc rod 8 can be used as a support frame to facilitate the placement of the entire device on the top of the relevant placement platform. This method can also be used to stably place the device on the top of the display platform when it is necessary to display the device to others.
