Technical Field
[0001] This utility model relates to the field of upper limb rehabilitation training technology, specifically to an upper limb proprioceptive assessment and training device. Background Technology
[0002] In recent years, research on proprioceptive intervention has gradually expanded from rehabilitation medicine to occupational health. For example, proprioceptive training with visual feedback has been shown to significantly improve upper limb function in stroke patients, and this method is also being explored for musculoskeletal health protection in the workplace. If patients use appropriate rehabilitation equipment during treatment, it will improve their upper limb function, enhance their daily living activities, and help them reintegrate into their families and society. Therefore, both patients and rehabilitation therapists need equipment that can effectively assist patients in relevant functional rehabilitation training.
[0003] Existing upper limb proprioceptive assessment and training devices generally suffer from high operational complexity in terms of angle adjustment. This inefficient adjustment mechanism not only increases the workload of medical staff, but also reduces the practicality of the device because it cannot quickly adapt to the real-time rehabilitation needs of patients.

[0008] Preferably, the spring is fixedly connected to the connecting plate, the rope is fixedly connected to the connecting block, and the push block is slidably connected to the rope.
[0009] Preferably, a push rod is slidably connected inside the fixed rod, the ball is in rolling contact with the outside of the push rod, the fixed rod is slidably connected to the sliding groove on the moving block, and the circular groove on the moving block matches the outer circular surface of the ball.
[0010] Preferably, the fixing component includes a fixing seat fixed to the bottom of the tabletop, the fixing seat being hinged to a rotating arm, a fixing block being fixedly connected to one side of the rotating arm, a lead screw being rotatably connected inside the fixing block, a torsion block being fixedly connected to the bottom of the lead screw, an insert rod being fixedly connected to the top of the lead screw, a square groove being provided on one side of the fixing block, an insert block being fixedly connected to the bottom of the panel, a round hole being provided on one side of the insert block, and a slot being provided on one side of the tabletop.
[0011] Preferably, a pen holder is fixedly connected to the bottom of the table near the front end.
[0012] Preferably, a digital protractor is fixedly connected to one side of the panel.
[0013] This utility model has the following beneficial effects:
[0014] 1. This upper limb proprioceptive assessment and training device uses a rotary control handle to rotate a push block. The push block pulls a rope, which in turn pulls a moving plate to compress a spring. The moving plate then moves a push rod outward toward a fixed rod. The push rod then stops pushing the ball bearing to engage with the groove on the moving block. At this point, the table is flipped, allowing the fixed rod to slide in the groove on the moving block. Once the table is flipped to the desired angle, the rotary control handle is released. The spring pushes the moving plate and push rod back to their original positions, and the push rod then pushes the ball bearing to extend toward the fixed rod and engage with the groove on the moving block, thus locking the table. This makes the angle adjustment function of the device more convenient, reducing the workload of medical staff and allowing for rapid adaptation to the changing rehabilitation needs of patients, thereby significantly improving its practicality.
[0015] 2. This upper limb proprioceptive assessment and training device uses a rotating arm to rotate a fixed block, aligning the fixed block parallel to the table. The panel is then placed on the table, and the insert on the panel is inserted into the square slot on the fixed block. Rotating the torsion block causes the lead screw to rotate within the fixed block, which in turn causes the insert rod to insert into the round hole on the insert block until it passes through the insert block and enters the slot on the table. The panel is then fixed to the table. To replace the panel, simply rotate the torsion block in the opposite direction to move the insert rod out of the round hole on the insert block, allowing the panel to be removed from the table for replacement. This makes panel disassembly and replacement easy. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figure 1-11 As shown, the upper limb proprioception assessment and training device provided in this embodiment includes a leg frame 1, a first support leg 2 fixedly connected to the top of the leg frame 1, a second support leg 3 slidably connected to the outside of the first support leg 2, a connecting column 4 fixedly connected to the top of the second support leg 3, a connecting frame 5 slidably connected inside the connecting column 4, a table 6 fixedly connected to the top of the connecting frame 5, a lifting component 7 for raising and lowering the second support leg 3 provided on the table 6, a rotating component 8 for rotating the table 6 provided on the connecting frame 5, a panel 11 movably connected to the top of the table 6, and a fixing component 9 for fixing the panel 11 provided on the table 6.
[0033] Furthermore, the lifting assembly 7 includes a handle base 702 fixed to the bottom of the tabletop 6, a lifting control handle 703 rotatably connected inside the handle base 702, a gas spring hydraulic rod 704 fixedly connected inside the first support leg 2, and the top of the gas spring hydraulic rod 704 fixedly connected to the first support leg 2. The output end wire of the lifting control handle 703 is connected to a lifting control line 701, and one end of the lifting control line 701 is connected to the input end wire of the gas spring hydraulic rod 704.
[0034] By adopting the above technical solution, by pressing the lifting control handle 703 on the handle base 702, the lifting control handle 703 controls the extension and retraction of the gas spring hydraulic rod 704 through the lifting control line 701. The gas spring hydraulic rod 704 can then drive the second support leg 3 to move on the first support leg 2, thereby adjusting the height of the tabletop 6 as needed.
[0035] Furthermore, the rotating assembly 8 includes a fixed housing 804 fixed to one side of the connecting frame 5. A rotating rod 802 is rotatably connected inside the connecting frame 5. A rotating control handle 801 is fixedly connected to one side of the rotating rod 802, and a push block 803 is fixedly connected to one side of the rotating control handle 801. A connecting plate 805 and a connecting block 806 are fixedly connected inside the fixed housing 804. A fixed rod 807 is fixedly connected to one side of the fixed housing 804. A ball bearing 808 is slidably connected inside the fixed rod 807. A moving plate 809 is slidably connected inside the fixed housing 804. A push rod 810 is fixedly connected to one side of the moving plate 809. A groove 811 is provided on the outside of the push rod 810. A spring 812 and a rope 813 are fixedly connected to the other side of the moving plate 809. A moving block 814 is fixedly connected inside the fixed housing 804. A sliding groove 815 is provided on one side of the moving block 814. A circular groove 816 is provided on the inner wall of the sliding groove 815 on the moving block 814.
[0036] Furthermore, the spring 812 is fixedly connected to the connecting plate 805, the rope 813 is fixedly connected to the connecting block 806, and the push block 803 is slidably connected to the rope 813.
[0037] By adopting the above technical solution, the rotary control handle 801 drives the push block 803 to rotate through the rotating rod 802. The push block 803 then pulls the rope 813 during the movement, and the rope 813 pulls the moving plate 809 to compress the spring 812.
[0038] Furthermore, a push rod 810 is slidably connected inside the fixed rod 807, and the ball 808 is in rolling contact with the outside of the push rod 810. The fixed rod 807 is slidably connected to the sliding groove 815 on the moving block 814, and the circular groove 816 on the moving block 814 matches the outer circular surface of the ball 808.
[0039] By adopting the above technical solution, the push rod 810 is moved outward from the fixed rod 807 by the moving plate 809. The groove 811 on the push rod 810 moves to the ball 808. The push rod 810 no longer pushes the ball 808 to fit against the round groove 816 on the moving block 814. The ball 808 can then move completely into the fixed rod 807. The fixed rod 807 is no longer fixed and can slide in the sliding groove 815 on the moving block 814. Thus, the tabletop 6 can be flipped. Since the sliding groove 815 on the moving block 814 limits the flipping angle, the flipping angle of the tabletop 6 is between 0° and 90°.
[0040] Furthermore, the fixing component 9 includes a fixing seat 907 fixed to the bottom of the tabletop 6. The fixing seat 907 is hinged to the rotating arm 906. A fixing block 904 is fixedly connected to one side of the rotating arm 906. A lead screw 902 is rotatably connected inside the fixing block 904. A torsion block 901 is fixedly connected to the bottom of the lead screw 902. An insert rod 903 is fixedly connected to the top of the lead screw 902. A square groove 905 is opened on one side of the fixing block 904. An insert block 12 is fixedly connected to the bottom of the panel 11. A round hole 13 is opened on one side of the insert block 12. A slot 14 is opened on one side of the tabletop 6.
[0041] By adopting the above technical solution, the rotating arm 906 rotates on the fixed base 907, which in turn drives the fixed block 904 to rotate, thus aligning the fixed block 904 parallel to the tabletop 6 and aligning the insertion rod 903 with the slot 14 on the tabletop 6. Then, the panel 11 is placed on the tabletop 6, and the insertion block 12 on the panel 11 is inserted into the square slot 905 on the fixed block 904. Finally, the twisting block 901 is rotated, which drives the screw... The rod 902 rotates within the fixing block 904, which in turn drives the insertion rod 903 to insert into the round hole 13 on the insertion block 12 until the insertion rod 903 passes through the insertion block 12 and is inserted into the slot 14 on the tabletop 6. This fixes the panel 11 onto the tabletop 6. To replace the panel 11, simply rotate the twisting block 901 in the opposite direction to move the insertion rod 903 out of the round hole 13 on the insertion block 12. The panel 11 can then be removed from the tabletop 6 and replaced with another panel 11.
[0042] Furthermore, a pen holder 10 is fixedly connected to the bottom of the tabletop 6 near the front end.
[0043] By adopting the above technical solution, the pen holder 10 not only makes it convenient for patients to store their pens, but also makes them easy to access, making it very convenient to use.
[0044] Furthermore, a digital protractor 15 is fixedly connected to one side of the panel 11.
[0045] By adopting the above technical solution, the digital protractor 15 can more intuitively display the real-time angle change of the panel 11 after it is flipped, making it easier for medical staff to adjust the angle of the panel 11 according to the patient's condition.
[0046] Working principle: When the height of the tabletop 6 needs to be adjusted, press the lifting control handle 703 of the lifting assembly 7. The lifting control handle 703 will then drive the gas spring hydraulic rod 704 to adjust the height of the tabletop 6. When the panel 11 needs to be replaced, simply rotate the torsion block 901 of the fixing assembly 9 in the reverse direction to move the insertion rod 903 out of the round hole 13 on the insertion block 12. The panel 11 can then be removed from the tabletop 6 for replacement with another panel 11. When the angle of the tabletop 6 needs to be adjusted, press the rotation... The control handle 801, when rotated, drives the push block 803 to rotate via the rotating rod 802. During this movement, the push block 803 pulls the rope 813, which in turn pulls the moving plate 809 to compress the spring 812. The moving plate 809 then moves the push rod 810 outwards towards the fixed rod 807. The groove 811 on the push rod 810 then moves to the ball bearing 808, and the push rod 810 no longer pushes the ball bearing 808 to engage with the circular groove 816 on the moving block 814. The ball bearing 808 can then move completely to the fixed rod 807. Once the fixed rod 807 is inside the fixed rod 807, it is no longer fixed, allowing the tabletop 6 to be flipped. The fixed rod 807 can then slide in the groove 815 on the moving block 814. When the tabletop 6 is flipped to the desired angle, the rotation control handle 801 is released, and the spring 812 pushes the moving plate 809 to reset. The moving plate 809 then pulls the rope 813 to reset the rotation control handle 801. Simultaneously, the moving plate 809 drives the push rod 810 to move into the fixed rod 807, and the groove 811 on the push rod 810... The ball 808 moves out of its range, and the push rod 810 pushes the ball 808 out of the fixed rod 807, causing part of the ball 808 to extend out of the fixed rod 807. The extended part of the ball 808 then fits tightly against the circular groove 816 on the moving block 814, thus fixing the fixed rod 807 in place and preventing it from sliding in the sliding groove 815 on the moving block 814. This locks the table 6, preventing it from automatically flipping over during use, making its structure more stable, and making the device versatile and easy to operate.
[0047] like Figure 12-13 As shown, Figure 12 These are training images from the basic mode. Figure 13 This is the advanced mode training diagram, while panel 11 will be engraved with either the beginner or advanced mode training diagrams. Medical staff will change the panel 11 according to the patient's condition to help the patient carry out better rehabilitation training.
[0048] Although embodiments of the present invention have been shown and described, 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 present invention, the scope of which is defined by the appended claims and their equivalents.
