Abstract
Description
Technical Field
[0001] This invention relates to the field of rehabilitation training equipment technology, specifically to a gravity-adjustable arm fracture training device. Background Technology
[0002] Patients with arm movement disorders caused by fractures, hemiplegia, or stroke generally need to undergo arm rehabilitation training to restore muscle and nerve function in their arms. However, routine rehabilitation training requires the accompaniment of a doctor, is expensive, and is limited in time.
[0003] Chinese Patent Publication No. CN214074912U discloses an arm strength rehabilitation training device. It consists of a spring, a second spring, a third spring, a push plate, a slide rail, a connecting rod, and a foam board. During rehabilitation training, the patient pushes the foam board, which helps prevent hand injury. The push plate and slide rail are connected by a slider. The patient can push the foam board to move the push plate, which then contacts the springs, thus achieving strength training and rehabilitation. Later, when the rehabilitation training requirements increase, the patient can increase the force, causing the push plate to contact the second and third springs, generating greater resistance and increasing the difficulty of the training. This allows the device to adapt to different training stages.
[0004] Although this arm strength rehabilitation training device is equipped with a massage pad for massaging patients, the arm rehabilitation training device cannot massage the arm during the arm training process, and the massage effect of the massage pad is not efficient. Medical staff still need to massage the patient's arm, which increases the burden on medical staff.
[0005] To address this, a gravity-adjustable arm fracture training device is proposed. Summary of the Invention
[0006] This invention relates to the field of rehabilitation training equipment technology, and aims to address the shortcomings of existing technologies by proposing a gravity-adjustable arm fracture training device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A gravity-adjustable arm fracture training device includes a table. Support legs are fixedly installed on the left and right sides of the lower end face of the table. A sliding groove is formed on the left and right sides of the upper end face of the table. Teeth are fixedly installed on the inner wall of the sliding groove. A massage mechanism is provided on the upper side of the table, and an intensity adjustment mechanism is provided on the lower side of the table. The massage mechanism includes a rotating shaft located on the lower side of the sliding groove, which is rotatably connected to the table. A support is fixedly installed at the upper end of the rotating shaft. A worm gear is rotatably connected to the rear side of the lower end face of the support. A gear is fixedly installed at the lower end of the worm gear, and the gear is located inside the sliding groove and meshes with the teeth. Bandages are fixedly installed on the front and rear sides of the upper end face of the support.
[0009] Furthermore, the massage mechanism also includes support members fixedly installed on both the front and rear sides of the lower end of the support platform, and a threaded rod is rotatably connected between the two sets of support members, with a turbine fixedly installed at the rear end of the threaded rod.
[0010] Furthermore, the outer surface of the threaded rod is helically connected to a threaded sleeve, and the upper end face of the support is provided with a second sliding groove corresponding to the threaded rod. A connecting member is slidably connected inside the second sliding groove, and the upper end of the connecting member is fixedly connected to the threaded sleeve.
[0011] Furthermore, a clamping plate is rotatably connected to the upper end of the connector, a massage wheel is rotatably connected to the inner wall of the clamping plate, and a spring is fixedly installed between the connector and the clamping plate.
[0012] Furthermore, the clamp is arc-shaped, and the massage rollers are arranged in multiple sets and are evenly distributed.
[0013] Furthermore, the support member, threaded rod, turbine, threaded sleeve, connector, slide groove, clamping plate and massage wheel are each provided in two sets and are arranged symmetrically. Both sets of turbines are meshed and connected to the worm gear for transmission.
[0014] This application incorporates a massage mechanism that utilizes the force generated by the patient's exercise to power the massage mechanism, massaging the patient's arm and promoting blood circulation, thereby accelerating the patient's recovery time and improving the practicality of the equipment.
[0015] Furthermore, the strength adjustment mechanism includes a slide rail fixedly installed on the lower end of the table corresponding to the slide groove, a connecting rod provided on the front side of the slide rail, and the lower end of the rotating shaft passing through the table and extending to the lower side to be fixedly connected to the front end of the connecting rod.
[0016] Furthermore, a slider is slidably connected to the left side of the slide rail, and the rear end of the connecting rod extends into the interior of the slide rail and is fixedly connected to the slider. An adjusting block is slidably connected to the right side of the slide rail, and a spring is fixedly installed between the adjusting block and the slider. Both the slide rail and the spring are arranged in an arc shape corresponding to the slide groove.
[0017] Furthermore, multiple sets of gear holes are provided on the right side of the upper end face of the slide rail one, and a handle is fixedly installed on the left side of the outer surface of the adjusting block. A rod is inserted into the interior of one set of gear holes corresponding to the adjusting block.
[0018] The beneficial effects of this invention are:
[0019] 1. This application incorporates a massage mechanism. When a patient uses this device for exercise, they first place their arm on the support platform. Then, the arm is secured to the platform using two sets of bandages. After securing, the arm can be swung and rotated. A rotating shaft fixedly installed on the front side of the lower end of the support platform rotates. This rotation of the shaft synchronously causes a slider to slide inside a slide rail via a connecting rod, thereby compressing a spring within the slide rail. The spring generates resistance, achieving the purpose of exercising the patient's arm. Simultaneously, a worm gear rotatably connected to the rear side of the lower end of the support platform slides back and forth inside a slide groove. A gear fixedly installed at the lower end of the worm gear moves synchronously... The sliding mechanism connects the gears to the teeth inside the slide groove, driving the worm to rotate. The worm gears on both sets of threaded rods mesh with the worm, causing them to rotate synchronously. The threaded sleeves connected to the outer surface of the threaded rods move on their own surface as the rods rotate, carrying the clamping plate along with them. The clamping plate, held in place by a spring, moves across the patient's arm, carrying the massage rollers and massaging the arm to promote blood circulation and accelerate recovery.
[0020] 2. This application incorporates an intensity adjustment mechanism. As the patient's exercise time increases and the patient gradually recovers, the current exercise intensity of the device may not provide a good exercise effect. In this case, by pulling the plug out of the current gear hole and then moving the adjustment block backward using the handle, the spring is compressed, shortening its length and increasing its elastic strength. The plug is then inserted into the adjusted gear hole, allowing for exercise to resume. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below are only some embodiments of the present invention, and not all embodiments.
[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] Reference Figure 1-7A gravity-adjustable arm fracture training device includes a table 1. Support legs 2 are fixedly installed on the left and right sides of the lower end face of the table 1. Slide grooves 3 are formed on the left and right sides of the upper end face of the table 1. Teeth 4 are fixedly installed on the inner wall of the slide grooves 3. A massage mechanism is provided on the upper side of the table 1, and an intensity adjustment mechanism is provided on the lower side of the table 1. The massage mechanism includes a rotating shaft 5 located on the lower side of the slide grooves 3, which is rotatably connected to the table 1. A support platform 6 is fixedly installed on the upper end of the rotating shaft 5. A worm gear 7 is rotatably connected to the rear side of the lower end face of the support platform 6. A gear 8 is fixedly installed on the lower end of the worm gear 7. The gear 8 is located inside the slide grooves 3 and meshes with the teeth 4. Bandages 17 are fixedly installed on the front and rear sides of the upper end face of the support platform 6. The massage mechanism also includes support members 9 fixedly installed on the front and rear sides of the lower end face of the support platform 6. The two sets of support members 9... A threaded rod 10 is rotatably connected to the support 9. A turbine 11 is fixedly installed at the rear end of the threaded rod 10. A threaded sleeve 12 is helically connected to the outer surface of the threaded rod 10. A second groove 13 is opened on the upper end face of the support 6 corresponding to the threaded rod 10. A connector 14 is slidably connected inside the second groove 13. The upper end of the connector 14 is fixedly connected to the threaded sleeve 12. A clamping plate 15 is rotatably connected to the upper end of the connector 14. A massage wheel 16 is rotatably connected to the inner wall of the clamping plate 15. A second spring 23 is fixedly installed between the connector 14 and the clamping plate 15. The clamping plate 15 is arc-shaped. Multiple sets of massage wheels 16 are provided and are evenly distributed. Two sets of each of the support 9, threaded rod 10, turbine 11, threaded sleeve 12, connector 14, second groove 13, clamping plate 15 and massage wheels 16 are provided and are symmetrically arranged. Both sets of turbines 11 are meshed and connected to the worm gear 7.
[0032] Specifically, existing arm rehabilitation training devices cannot massage the arm during training, requiring medical staff to massage the patient's arm, increasing their workload. Furthermore, existing devices cannot adjust the resistance during arm movement, demanding only minimal effort from the patient, thus reducing the effectiveness of rehabilitation. Therefore, this application addresses this by incorporating a massage mechanism that utilizes the force generated during exercise to drive the massage mechanism, massaging the patient's arm, promoting blood circulation, and accelerating recovery time. This significantly improves the device's practicality. Specifically, when using the device, the patient first places their arm on the platform 6, then secures it with two sets of bandages 17. After securing, the arm can be swung and rotated, causing the rotating shaft 5, fixedly mounted on the front of the lower end of the platform 6, to rotate. The rotation of the shaft 5 synchronously drives the slider 20 within the slide rail 19 via the connecting rod 18. The movement of the spring 22 inside the slide rail 19 compresses the arm, creating resistance and thus providing a single-arm exercise for the patient. Simultaneously, the worm gear 7, rotatably connected to the lower end of the support platform 6, slides back and forth inside the slide groove 3. The gear 8, fixedly mounted at the lower end of the worm gear 7, slides synchronously and engages with the teeth 4 inside the slide groove 3, driving the worm gear 7 to rotate. The turbines 11 on both sets of threaded rods 10 engage with the worm gear 7, driving both sets of threaded rods 10 to rotate synchronously. The threaded sleeve 12, helically connected to the outer surface of the threaded rod 10, displaces on the outer surface of the threaded rod 10 as it rotates, carrying the clamp 15 along with it. The clamp 15, held in close contact with the patient's arm by the spring 23, moves along the patient's arm, carrying the massage roller 16 to massage the arm, promoting blood circulation and accelerating recovery.
[0033] like Figure 2 As shown, the intensity adjustment mechanism includes a slide rail 19 fixedly installed on the lower end of the table 1 corresponding to the slide groove 3. A connecting rod 18 is provided on the front side of the slide rail 19. The lower end of the rotating shaft 5 passes through the table 1 and extends to the lower side to be fixedly connected to the front end of the connecting rod 18. A slider 20 is slidably connected to the left side inside the slide rail 19. The rear end of the connecting rod 18 extends into the interior of the slide rail 19 and is fixedly connected to the slider 20. An adjusting block 21 is slidably connected to the right side inside the slide rail 19. A spring 22 is fixedly installed between the adjusting block 21 and the slider 20. The slide rail 19 and the spring 22 are both arranged in an arc shape corresponding to the slide groove 3. Multiple sets of stop holes 24 are opened on the right side of the upper end of the slide rail 19. A handle 26 is fixedly installed on the left side of the outer surface of the adjusting block 21. A plug rod 25 is inserted into the interior of one set of stop holes 24 corresponding to the adjusting block 21.
[0034] Specifically, as the patient's exercise time increases and the patient gradually recovers, the current exercise intensity of the equipment may not provide a good exercise effect. At this time, by pulling the plug 25 out of the current gear hole 24, and then moving the adjustment block 21 to the rear using the handle 26, the spring 22 is compressed, shortening its length and increasing its elastic strength. Then, the plug 25 is inserted into the adjusted gear hole 24, and the exercise can be resumed.
[0035] When using this invention, the patient first places their arm on the support platform 6, then secures it to the platform 6 with two sets of bandages 17. After securing, the arm can be swung and rotated, causing the rotating shaft 5 fixedly installed on the front side of the lower end face of the support platform 6 to rotate. The rotation of the rotating shaft 5 synchronously causes the slider 20 to slide inside the slide rail 19 via the connecting rod 18, thereby compressing the spring 22 installed inside the slide rail 19. The spring 22 generates resistance, achieving the purpose of exercising the patient's arm. Meanwhile, the worm gear 7 rotatably connected to the rear side of the lower end face of the support platform 6 slides back and forth inside the slide groove 3. The gear 8 fixedly installed at the lower end of the worm gear 7 slides synchronously, and the gear 8 meshes with the teeth 4 installed inside the slide groove 3, thus driving the worm gear 7 to rotate. The worm gears 11 on both sets of threaded rods 10 mesh with the worm gear 7, thus driving both sets of threaded rods 10 to rotate synchronously. When the threaded rod 10 rotates, the threaded sleeve 12, which is connected to the outer surface of the threaded rod 10 by a helical drive, will move on the outer surface of the threaded rod 10 and carry the clamp 15 to move through the connecting component. The clamp 15 is in close contact with the patient's arm through the second spring 23. Therefore, when the clamp 15 moves, it will carry the massage roller 16 to move on the patient's arm, thereby massaging the patient's arm, promoting blood circulation and accelerating recovery. As the patient's exercise time increases and the patient gradually recovers, the current exercise intensity of the device is not enough to provide a good exercise effect. At this time, by pulling the insertion rod 25 out of the current gear hole 24, and then moving the adjusting block 21 to the rear through the handle 26, the spring 22 is squeezed, shortening the length of the spring 22 and increasing the elastic strength of the spring 22. Then, the insertion rod 25 is inserted into the adjusted gear hole 24, and the exercise can be performed again.
[0036] It will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
