Description

Technical Field

[0001] This utility model pertains to rehabilitation training equipment, specifically hand training equipment, and more particularly to a hand function training device. Background Technology

[0002] When hand function is impaired due to neurological disorders or problems with the muscles of the musculoskeletal system, targeted hand rehabilitation training is crucial. Rehabilitation training must be tailored to the patient's specific condition, following a gradual progression, increasing the training volume step by step, arranging training content from simple to complex, and gradually extending the training duration from short periods. In hand function training, dorsiflexion exercises are an effective means to significantly improve wrist joint flexibility and muscle strength, thereby improving overall hand function. To achieve this goal, rehabilitation training often employs progressive exercises, such as resistance training using elastic bands, and combining active and passive wrist flexion and extension movements, aiming to help patients gradually restore the normal range of motion and strength of the wrist joint. However, a current challenge in rehabilitation training is the lack of standardized, readily available training equipment, which to some extent affects the optimization of training effects. Utility Model Content

[0003] This invention addresses the technical problem of the lack of well-designed training equipment for dorsiflexion training, which affects training effectiveness, by providing a hand function trainer. Utilizing a dorsiflexion panel, both finger splitting and dorsiflexion training can be performed. By controlling the rotation angle of the dorsiflexion panel, the intensity of dorsiflexion training can be controlled, thereby training the wrist muscle groups, preventing muscle atrophy and joint stiffness, reducing pain and discomfort in the patient's hand, and improving hand strength and flexibility.

[0004] The technical solution adopted by this utility model is as follows: a hand function trainer is provided, including a table, two dorsiflexion panels are arranged side by side on the front side of the top surface of the table, the dorsiflexion panels are rotatably mounted on the table and locked to the table by means of a locking component, and one side of the dorsiflexion panel is provided with a finger block, and the other side is provided with a stop bar in an adjustable position; two restraint straps are arranged side by side on the rear side of the top surface of the table, and the restraint straps are respectively matched with the position of the dorsiflexion panels.

[0005] When performing dorsiflexion training on a table, the arm is placed on the table and secured with straps. The palm rests on the dorsiflexion panel, which has finger-separating blocks and a stop bar on each side. When the patient needs finger-separating training, the side with the finger-separating blocks faces the patient's palm, and the fingers are placed between the blocks for separation. The wrist is then dorsiflexed by rotating the panel. When the patient does not need finger-separating training, the side with the stop bar faces the patient's palm, and the stop bar is adjusted to position itself against the web of the hand. The wrist is then dorsiflexed by rotating the panel. After the wrist is bent at a certain angle, the panel is locked using a locking mechanism to maintain a specific dorsiflexion angle, thus training the wrist muscles, preventing muscle atrophy and joint stiffness, reducing hand pain and discomfort, and improving hand strength and flexibility.

[0006] To further optimize this technical solution, two docking posts are arranged side by side on the front side of the top surface of the platform, and docking grooves are provided on both the front and rear sides of the bottom surface of the platform. The docking grooves are respectively inserted into the docking posts, and the locking assembly is located on the front side of the outer wall of the back-bending panel.

[0007] After the mating slot on the bottom of the backflex panel is inserted into the mating post, the backflex panel can be rotated along the mating post to perform backflexion training on the hand. Furthermore, the backflex panel can be used on both sides by swapping the two slots and inserting them into the mating post, ensuring flexibility in use.

[0008] To further optimize this technical solution, the top surface of the platform is provided with slots that match the docking posts, and the docking posts are respectively inserted into the slots.

[0009] The platform has slots for mounting docking posts, which facilitates disassembly and maintenance and ensures flexibility of use.

[0010] To further optimize this technical solution, the locking assembly includes a locking pin and a positioning groove. The locking pin is fixedly installed on the bottom of the back-bending panel, and the positioning groove is evenly distributed in an arc shape on the platform.

[0011] The positioning groove on the platform is set on the rotational movement path of the dorsiflexion panel. After the dorsiflexion panel pushes the palm to dorsiflex the angle, it pushes to shrink and engage with the positioning groove, thereby positioning the dorsiflexion panel to maintain the dorsiflexion angle of the palm, thereby training the patient's wrist muscles and improving the training effect.

[0012] To further optimize this technical solution, the back-bending panel is provided with connecting grooves on the side with the stop bar, and the stop bar is inserted into the connecting groove respectively.

[0013] The position of the lever is adjusted by inserting it into the connecting slot on the backbend panel. The structure is simple and the use is flexible and convenient.

[0014] To further optimize this technical solution, a set of through holes is arranged side by side on the rear side of the platform, and the two ends of the two binding straps pass through the through holes respectively.

[0015] The two ends of the restraint strap are connected to the platform by passing through the insertion holes. The structure is simple and the restraint strap is easy to assemble and disassemble.

[0016] To further optimize this technical solution, the restraint strap is made of nylon, with Velcro stitched on both sides of the nylon strap that can be bonded to each other, and both ends of the nylon strap pass through the threading hole.

[0017] Nylon straps are high in strength, wear-resistant, and have low usage and maintenance costs. They are easy to use and flexible because they are secured to the arm with Velcro.

[0018] To further optimize this technical solution, two arc-shaped guide grooves are symmetrically arranged on the top surface of the platform, and guide columns slide in each guide groove. The guide columns are fixedly connected to the back-bending panel respectively.

[0019] The guide groove is located on the moving path of the back-bending panel. When the back-bending panel rotates, it drives the guide column to move along the guide groove, ensuring the stability of the rotation.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. When performing wrist dorsiflexion training by rotating the dorsiflexion panel along the connecting post on the platform, finger-separating blocks and stops are set on both sides of the dorsiflexion panel. This allows for simultaneous dorsiflexion and finger-separation training for patients who cannot separate their fingers. For patients who can separate their fingers, the stop is inserted into the connecting slot on the dorsiflexion panel according to the size of the patient's palm to adjust the position and make it abut against the web of the patient's hand, thereby positioning the palm, ensuring the training effect, and improving versatility.

[0022] 2. When the dorsiflexion panel rotates, it drives the guide post to slide along the guide groove to ensure the stability of the dorsiflexion panel rotation. After the patient's palm is pushed to a certain angle, the locking pin is inserted into the positioning groove on the platform to lock the position of the dorsiflexion panel, thereby keeping the wrist in a dorsiflexion state and training the wrist muscle group. The dorsiflexion training angle of the wrist can be gradually increased according to the patient's training status to improve the flexibility of use.

[0023] 3. During back flexion training, the restraint strap is used to restrain the patient's arm. The two ends of the restraint strap are attached with Velcro, making the restraint operation simple and avoiding the movement of the arm position from affecting the training effect. The restraint strap is also easy to remove and can be used flexibly to ensure the safety of training. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Please see the appendix Figure 1 The hand function training device includes a platform 1. When performing rehabilitation training on patients, the platform 1 is placed on a table for use. It is flexible in use, and the platform 1 is detachably equipped with a dorsiflexion panel 2, a limiting clamp, and a restraint strap 3, which makes it easy to disassemble, store, and combine for use, thus improving the flexibility of use. During training, after the patient places his arm on the platform 1, two restraint straps 3 are arranged side by side on the rear side of the top surface of the platform 1. The restraint straps 3 bind the patient's arm, thereby restraining the patient's arm and preventing the swing of the handle from affecting the training effect.

[0031] Please see the appendix Figure 1 Appendix Figure 2 The binding strap 3 used to bind the patient is a nylon strap, and two sets of through holes 103 are arranged side by side on the platform 1 for threading the nylon strap. The two through holes 103 of the through hole 103 are arranged side by side on the platform 1, and the two ends of the nylon strap pass through the through holes 103 respectively. Both sides of the nylon strap are sewn with Velcro that can be glued to each other. By using Velcro to glue the two ends of the nylon strap together, the patient's arm placed on the platform 1 is bound. The operation is simple.

[0032] Please see the appendix Figure 1After the restraint strap 3 tightens the patient's arm, a dorsiflexion panel 2 is provided on the front of the top of the table 1. In order to train the patient's left and right hands separately, two dorsiflexion panels 2 are provided on the table 1 and are symmetrically arranged on the table 1 and rotated with the table 1. One side of the dorsiflexion panel 2 is provided with finger-separating blocks 201. When the patient receiving rehabilitation training cannot separate his / her fingers, he / she can perform finger-separating training by placing his / her fingers in the gap between the finger-separating blocks 201. When training patients who can separate their fingers, the other side of the dorsiflexion panel 2 is provided with a stop bar 202. The stop bar 202 can be adjusted in position according to the size of the patient's hand so that the stop bar 202 rests against the web of the hand to restrain the patient's hand.

[0033] Please see the appendix Figure 1 The backrest panel 2 has a connecting groove 205 evenly arranged on one side where the stop bar 202 is provided. The position of the stop bar 202 can be adjusted by inserting the stop bar 202 into the connecting groove 205 at the appropriate position. The operation is simple and the use is flexible.

[0034] Please see the appendix Figure 1 Appendix Figure 3 When the patient's palm is pressed against the dorsiflexion panel 2, and the dorsiflexion panel 2 is rotated to push the patient's hand to flex backward, the top surface of the platform 1 has two slots 101 arranged side by side, and the two slots 101 are respectively inserted into the docking post 4. The bottom surface of the platform 1 has docking grooves 203 on both the front and back sides. After the docking grooves 203 are inserted into the docking post 4, the dorsiflexion panel 2 can be rotated along the docking post 4 to perform dorsiflexion training on the hand. The dorsiflexion panel 2 can be used on both sides by changing the two slots 101 and the docking post 4.

[0035] Please see the appendix Figure 1 Appendix Figure 4 When the back-bending panel 2 rotates along the docking column 4, two arc-shaped guide grooves 104 are symmetrically arranged on the top surface of the platform 1. Guide columns 5 slide in the guide grooves 104 respectively. The guide columns 5 are fixedly connected to the bottom surface of the back-bending panel 2. The guide grooves 104 are opened on the moving path of the back-bending panel 2. When the back-bending panel 2 rotates, it drives the guide columns 5 to move along the guide grooves 104 to ensure the stability of the rotation.

[0036] Please see the appendix Figure 1After the dorsiflexion panel 2 dorsiflexes the patient's hand to a certain angle, the dorsiflexion panel 2 is locked onto the platform 1 by means of a locking assembly, so that the patient can adapt to the dorsiflexion angle. The locking assembly consists of a matching locking pin 204 and a positioning groove 102. The locking pin 204 is assembled at the bottom of the dorsiflexion panel 2, and the positioning groove 102 is evenly distributed in an arc shape on the platform 1. When the dorsiflexion panel 2 rotates along the docking post 4, the rotation path of its front end is arc-shaped, and the positioning groove 102 is distributed on the path of the dorsiflexion panel 2. After the locking pin 204 is inserted into the positioning groove 102, the position of the dorsiflexion panel 2 is fixed, and the operation is simple.

[0037] To ensure the training effect when performing dorsiflexion training on the patient's hand, a limiting clamp can be set between the dorsiflexion panel 2 and the restraint strap 3 to increase the limiting points on the arm and prevent arm movement from interfering with the training effect. The limiting clamp can be adjusted on the platform 1 to adapt to the limiting position of the arm. The limiting clamp includes two clamps. The two clamps are connected to the evenly distributed slots on the platform 1 by setting positioning parts to realize the positioning of the two clamps and the clamping restriction of the arm. The positioning parts can be selected as pin structures according to the usage requirements. After being assembled with the clamps, the clamps are positioned by inserting the pins into the slots. Alternatively, screws can be added to the clamps. The clamps are positioned by tightening the screws into the slots. This ensures the flexibility and reliability of the clamps in clamping the arm, while ensuring the training effect on the patient's hand.

[0038] The working principle of this hand function training device is as follows: After placing the platform 1 on the table, the patient places their left hand, right hand, or both hands simultaneously on the platform 1 according to their training needs. At this time, the two dorsiflexion panels 2 on the platform 1 are arranged in parallel. The patient places their palm on the dorsiflexion panel 2. When finger separation training is required, the patient's palm rests on the side with the finger separation block 201. When the patient does not need finger separation training, their palm rests on the side with the stop bar 202. By inserting the stop bar 202 into the connecting groove 205 on the dorsiflexion panel 2, the position of the stop bar 202 is adjusted so that it abuts against the web of the palm, thereby positioning the patient's palm. Then, the restraint strap 3 is used to restrain the patient's arm, thereby restricting the arm. Then, the dorsiflexion panel 2 is rotated along the docking post 4 to push the patient's wrist to perform dorsiflexion training. After the wrist is dorsiflexed to a certain angle, the locking pin 204 on the dorsiflexion panel 2 is inserted into the positioning groove 102 on the platform 1 to lock the position of the dorsiflexion panel 2. This keeps the patient's wrist dorsiflexed and exercises the extensor carpi radialis longus, extensor carpi brevis, and extensor carpi ulnais muscles of the wrist. As the training effect improves, the rotation angle of the dorsiflexion panel 2 is gradually increased so that the hand function gradually returns to normal or approaches normal, preventing muscle atrophy and joint stiffness, reducing the patient's hand pain and discomfort, and improving the strength and flexibility of the hand.
