Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training technology, specifically a rehabilitation finger trainer. Background Technology

[0002] Fingers are the five branches at the front of the hand, one of the five terminal parts of the palm. Generally, there are five fingers: thumb, index finger, middle finger, ring finger, and little finger. With frequent use, the hand is very susceptible to external injuries, such as fractures, tendon ruptures, and burns. In addition, hand dysfunction is a common problem among hemiplegic patients, and hand exercises are required after some neurosurgical procedures to achieve rehabilitation.

[0003] Existing finger rehabilitation trainers work by pressing a resistance block, especially on the fingers other than the thumb, and through repeated force and relaxation, to exercise and accelerate rehabilitation. However, some existing simple finger rehabilitation trainers require a fixed amount of force, which cannot be adjusted according to the patient's actual situation, resulting in poor rehabilitation effects and low training efficiency. In addition, some patients often have hand tremors, so the rehabilitation trainer may not fit properly, causing inconvenience. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a rehabilitation finger trainer, including a base 1, an arc-shaped baffle 2 fixedly connected to the left outer wall of the base 1, and a pressing mechanism 3 provided at the top of the base 1.

[0027] The pressing mechanism 3 includes an arc-shaped support plate 31. The top of the arc-shaped support plate 31 is arc-shaped, which can better fit the shape of the palm and make it more comfortable to place. The bottom end of the arc-shaped support plate 31 is fixedly connected to the top end of the base 1. A pressing block 32 is hinged to the left side wall of the base 1. The interior of the pressing block 32 is hollow, which can effectively reduce its weight. Sliding grooves are formed on both side walls of the pressing block 32. A sliding rod 310 is slidably connected to the inner wall of the sliding groove. When the pressing block 32 presses down, it can squeeze the top end of the sliding rod 310, thereby causing the sliding rod 310 to move along the sliding groove. The inner wall allows for some movement, providing sufficient space to avoid interference. A movable rod 33 is fixedly connected to the center of the sliding rod 310, and a fixed sleeve 34 is slidably connected to the outer wall of the movable rod 33. The movable rod 33 can move vertically along the inner wall of the fixed sleeve 34. The bottom end of the movable rod 33 is fixedly connected to one end of the return spring 35, and the other end of the return spring 35 is fixedly connected to the top end of the fixed sleeve 34. The elasticity of the return spring 35 requires a certain force to press the pressing block 32, thus providing finger pressing exercises, which is beneficial for postoperative nerve surgery. For rehabilitation, a sliding plate 36 is fixedly connected to the bottom end of the fixed sleeve 34. The outer wall of the sliding plate 36 is slidably connected to the inner side wall of the arc-shaped baffle 2. A slider 37 is slidably connected to the inner wall of the arc-shaped baffle 2. The side wall of the slider 37 is fixedly connected to the outer side wall of the sliding plate 36. By moving the sliding plate 36 to adjust its vertical position, the initial compression state of the reset spring 35 can be changed, thereby adjusting the magnitude of the reaction force of the reset spring 35 and adjusting the required pressing force, thus adapting to different patients. An adjusting bolt is threadedly connected to the inner wall of the slider 37. 38. A fixing block 39 is rotatably connected to the bottom end of the adjusting bolt 38. The fixing block 39 is fixedly connected to the outer side wall of the arc-shaped baffle 2. A knob with a groove is fixedly connected to the top end of the adjusting bolt 38, which can increase the friction between the finger and the adjusting bolt 38, making it easier to rotate the adjusting bolt 38. By rotating the adjusting bolt 38, the slider 37 can be controlled to move vertically along the adjusting bolt 38. Several sets of partitions 311 are fixedly connected to the left outer wall of the base 1. The partitions 311 can isolate different fingers, allowing them to press the pressing block 32 individually.

[0028] An arc-shaped sleeve 4 is fixedly connected to the right side wall of the base 1 via a connecting rod. An arc-shaped sliding plate 5 is slidably connected to the inner wall of the arc-shaped sleeve 4. The center of the arc-shaped sleeve 4 and the center of the arc-shaped sliding plate 5 coincide, allowing the arc-shaped sliding plate 5 to move along the trajectory of the arc-shaped sleeve 4. This provides a certain degree of restraint to the patient's wrist, preventing it from detaching from the device due to hand tremors and maintaining hand stability. A magnet 6 is fixedly connected to the top of the arc-shaped sliding plate 5, and a magnetic metal is fixedly connected to the outer wall of the top of the arc-shaped sleeve 4. The attraction between the magnet 6 and the magnetic metal provides a certain degree of restraint to the arc-shaped sliding plate 5, keeping it in a closed state without being affected by external forces. A lever 7 is fixedly connected to the outer wall of the arc-shaped sliding plate 5. The lever 7 is slidably connected to the inner wall of the arc-shaped sleeve 4 and extends outside the arc-shaped sleeve 4. Moving the lever 7 can drive the arc-shaped sliding plate 5 to move.

[0029] In this invention, during use, the palm is placed face down on the arc-shaped support plate 31, and the wrist is placed on the arc-shaped sleeve 4. With the assistance of the operator, the lever 7 is moved, causing the arc-shaped sliding plate 5 to move along the arc-shaped sleeve 4, thus sealing the arc-shaped sliding plate 5 and the arc-shaped sleeve 4, fixing the wrist. The magnet 6 attracts the magnetic metal at the top of the arc-shaped sleeve 4, providing a certain limiting effect. The fingers are placed on the pressing block 32, and the pressing mechanism 3 separates the fingers except the thumb. The pressing block 32 is then pressed, causing it to fold downwards along the hinge of the base 1, thus squeezing the sliding rod 310. The sliding rod 310 then moves along the inner wall of the pressing block 32. The sliding mechanism causes the sliding rod 310 to press against the moving rod 33 and the return spring 35 at its bottom. Repeated pressing helps to train and rehabilitate the fingers. When the pressing force needs to be adjusted, the adjusting bolt 38 can be rotated to move the slider 37 upward. This causes the slider 37 to move the sliding plate 36 and the fixing sleeve 34 upward, pressing against the return spring 35 and changing its initial state to adjust the pressing force. At the same time, the top of the pressing block 32 is locked in the groove of the arc-shaped support plate 31. The inner wall of this groove is in contact with the top of the pressing block 32, which restricts the pressing block 32 to a certain extent, keeping it horizontal and preventing it from folding upward. This allows the force required to press the pressing block 32 to be adjusted.

[0030] 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.
