Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a finger rehabilitation training aid device. Background Technology

[0002] In the field of medical rehabilitation, the restoration of finger function is crucial for many patients whose finger movement is limited due to hand injuries, neurological diseases, or congenital hand dysfunction. As an extremely delicate and flexible organ of movement, the fingers are responsible for many key daily activities such as grasping, pinching, and manipulating. Whether their function is normal or not directly affects the patient's ability to take care of themselves and their quality of life.

[0003] A modular integrated finger and wrist rehabilitation training device, disclosed in publication number CN222738216U, includes a base module, a finger rehabilitation training module, and a wrist rehabilitation training module. Driven by multiple motors, the device can perform individual rehabilitation training for the fingers or wrist, as well as coordinated rehabilitation training for both. However, it lacks the function of adjusting the training tension, making it impossible to adjust the training difficulty to suit different rehabilitation stages. In the early stages of rehabilitation, excessive tension can prevent patients from completing training movements, increasing frustration and affecting their motivation. In the later stages of rehabilitation, insufficient tension cannot provide adequate training intensity, leading to poor rehabilitation results, prolonged rehabilitation periods, and reduced user comfort.

[0004] Therefore, it is necessary to design a finger rehabilitation training aid that can adjust the tension of the second telescopic spring to facilitate the adjustment of training difficulty to suit different rehabilitation stages, prevent secondary injury, reduce discomfort, and provide a comfortable and safe finger rehabilitation training aid. Utility Model Content

[0005] To overcome the shortcomings of current devices, such as the inability to adjust the training difficulty to suit different rehabilitation stages, excessive tension in the early stages of rehabilitation leading to patients' inability to complete training movements and increased frustration, and insufficient tension in the later stages of rehabilitation failing to provide sufficient training intensity, resulting in poor rehabilitation effects and prolonged rehabilitation periods, this invention provides a finger rehabilitation training auxiliary device that can adjust the tension of the second telescopic spring to perform rehabilitation training on the patient's fingers. This allows for easy adjustment of the training difficulty to suit different rehabilitation stages, prevents secondary injuries, reduces discomfort, and provides a comfortable and safe experience.

[0006] The technical solution is as follows: A finger rehabilitation training auxiliary device includes a fixed plate, a sliding frame, an adjusting frame, a first connecting block, a telescopic rod, a second connecting block, a finger sleeve, a fixing component, a limiting component, and an adjusting component. The sliding frame is slidably connected to the fixed plate, and the adjusting frame is slidably connected to the right side of the sliding frame. Multiple first connecting blocks are rotatably connected to the upper part of the adjusting frame. A telescopic rod is rotatably connected to each of the first connecting blocks. A second connecting block is rotatably connected to the fixed end of each telescopic rod. A finger sleeve is rotatably connected to each of the second connecting blocks. The fixed plate is provided with a fixing component for fixing the position of the sliding frame. The sliding frame is provided with a limiting component for limiting the position of the adjusting frame. The telescopic rod is provided with an adjusting component for adjusting the training intensity.

[0007] Optionally, the sliding frame is L-shaped.

[0008] Optionally, the fixing component includes a screw and a fixing sleeve. The screw is rotatably connected to the upper right part of the fixing plate. The screw passes through the sliding frame, and the fixing sleeve is threadedly connected to the screw. The fixing sleeve contacts the sliding frame.

[0009] Optionally, the limiting component includes a guide rod, a limiting block, and a first telescopic spring. The guide rod is connected to the upper right part of the sliding frame. The guide rod is slidably connected to both the front and rear parts of the guide rod. The limiting blocks are slidably connected to the sliding frame and slidably engaged with the adjusting frame. The first telescopic spring connects the limiting blocks to the sliding frame.

[0010] Optionally, the guide rod is I-shaped.

[0011] Optionally, the adjusting assembly includes threads, a threaded sleeve, a connecting plate, and a second telescopic spring. The fixed end of the telescopic rod is provided with threads on its outer side, and a threaded sleeve is connected to the fixed end of the telescopic rod through the threads. A connecting plate is rotatably connected to the threaded sleeve, and a second telescopic spring is connected between the connecting plate and the telescopic end of the adjacent telescopic rod.

[0012] Beneficial effects: 1. This utility model adjusts the tension of the second telescopic spring by rotating the screw sleeve to move the connecting plate. After adjustment, the finger is inserted into the finger sleeve, and rehabilitation training is carried out by flexing and extending the finger. This allows for adjustment of the tension of the second telescopic spring to carry out rehabilitation training for the patient's finger, making it easy to adjust the training difficulty to adapt to different rehabilitation stages, preventing secondary injury, reducing discomfort, and ensuring comfortable and safe use.

[0013] 2. This utility model moves the sliding frame, which in turn moves the adjusting frame. The adjusting frame is then fixed by the moving fixed sleeve. Pulling the adjusting frame moves the telescopic rod, which adjusts the position of the finger sleeve. After the adjusting rod is adjusted, the limiting block is released to fix it. This allows the position and height of the finger sleeve to be adjusted to suit different patients for finger rehabilitation training, improving treatment effectiveness and comfort, expanding the scope of application, and making it more flexible to use.

Detailed Implementation

[0020] 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.

[0021] A finger rehabilitation training assistive device, such as Figures 1-5 As shown, the system includes a fixed plate 1, a sliding frame 2, an adjusting frame 5, a first connecting block 9, a telescopic rod 10, a second connecting block 15, a finger sleeve 16, a fixing component, a limiting component, and an adjusting component. The sliding frame 2 is slidably connected to the fixed plate 1. The sliding frame 2 is L-shaped for easy support. The adjusting frame 5 is slidably connected to the right side of the sliding frame 2. Four first connecting blocks 9 are rotatably connected to the upper part of the adjusting frame 5. A telescopic rod 10 is rotatably connected to each of the first connecting blocks 9. A second connecting block 15 is rotatably connected to the fixed end of each telescopic rod 10. A finger sleeve 16 is rotatably connected to each of the second connecting blocks 15. The fixed plate 1 is provided with a fixing component for fixing the position of the sliding frame 2. The sliding frame 2 is provided with a limiting component for limiting the position of the adjusting frame 5. The telescopic rod 10 is provided with an adjusting component for adjusting the training intensity.

[0022] like Figure 1 and Figure 2 As shown, the fixing assembly includes a screw 3 and a fixing sleeve 4. The screw 3 is rotatably connected to the upper right part of the fixing plate 1. The screw 3 passes through the sliding frame 2. The fixing sleeve 4 is connected to the screw 3 by a thread 11. The fixing sleeve 4 is in contact with the sliding frame 2.

[0023] like Figure 3 As shown, the limiting assembly includes a guide rod 6, a limiting block 7, and a first telescopic spring 8. The guide rod 6 is connected to the upper right part of the sliding frame 2. The guide rod 6 is I-shaped to facilitate guidance. The front and rear parts of the guide rod 6 are slidably connected to the limiting block 7. The limiting block 7 is slidably connected to the sliding frame 2. The limiting block 7 is slidably engaged with the adjusting frame 5. The first telescopic spring 8 is connected between the limiting block 7 and the sliding frame 2.

[0024] like Figure 4 and Figure 5 As shown, the adjustment assembly includes a thread 11, a threaded sleeve 12, a connecting plate 13, and a second telescopic spring 14. The fixed end of the telescopic rod 10 is provided with a thread 11 on its outer side. The fixed end of the telescopic rod 10 is connected to a threaded sleeve 12 through the thread 11. The threaded sleeve 12 is rotatably connected to a connecting plate 13. The connecting plate 13 is connected to the telescopic end of the adjacent telescopic rod 10 with a second telescopic spring 14.

[0025] This device can be used when assisting with finger rehabilitation training. The patient's hand passes through the fixing plate 1, and the device is secured to the hand using the straps on the fixing plate 1. Then, depending on the length of the patient's fingers, rotating the screw 3 causes the fixing sleeve 4 to move and disengage from the sliding frame 2 under the action of the thread 11. Pushing the sliding frame 2 then moves the adjusting frame 5. After moving to the appropriate position, rotating the screw 3 in the opposite direction causes the fixing sleeve 4 to move back to its original position and engage with the sliding frame 2 for fixation. The sliding frame 2 is L-shaped. Pressing the limiting block 7 moves it along the guide rod 6, compressing the first telescopic spring 8. This then pulls the adjusting frame 5, moving the telescopic rod 10 and adjusting the position of the finger sleeve 16. After adjusting to the appropriate height, releasing the limiting block 7 causes the first telescopic spring 8 to return, and the limiting block 7 moves back to its original position and engages with the adjusting frame 5 for fixation. This allows for adjustment of the position and height of the finger sleeve 16 to accommodate different patients' finger rehabilitation training, improving treatment effectiveness and user comfort. The device is designed to be flexible and adaptable, with an I-shaped guide rod 6. After fixing, rotating the screw sleeve 12 causes the screw sleeve 12 to move under the action of the thread 11, which in turn moves the connecting plate 13. This stretches and adjusts the tension of the second telescopic spring 14. After adjustment, the finger is inserted into the finger sleeve 16, and rehabilitation training is performed by flexing and extending the finger. This pulls the second connecting block 15 to move and then reset, causing the telescopic rod 10 to extend and then retract. The second telescopic spring 14 is stretched and then rebounds, causing the telescopic rod 10, the first connecting block 9, and the second connecting block 15 to rotate. This allows for repeated flexion and extension of the finger for rehabilitation training. The device allows for adjustment of the tension of the second telescopic spring 14 to perform rehabilitation training on the patient's finger, making it easy to adjust the training difficulty to suit different rehabilitation stages, preventing secondary injury, reducing discomfort, and ensuring comfortable and safe use. After training, the straps are loosened, the fixing plate 1 is removed from the patient's hand, and the finger is taken out of the finger sleeve 16. The device can then be placed on a table.
