Abstract
Description
[Technical Field]
[0001] The present invention relates to a hand training device, and more particularly to a hand training device for stroke patients. [Background technology]
[0002] Stroke patients often suffer from motor dysfunction in the hands, and hand muscle strength recovery and flexibility training are important steps in rehabilitation treatment. Current hand rehabilitation training devices used in clinical settings generally suffer from problems such as poor fit and difficulty adjusting the force. Specifically, many devices have a fixed structure, making it difficult to flexibly adapt to the size and shape of each patient's palm. As a result, training is less comfortable and the fit is insufficient, which can affect the effectiveness of training. Furthermore, adjusting the force of conventional devices often requires disassembly and complex operations using tools to replace the elastic components. This complicated adjustment process makes it difficult to quickly respond to changing muscle strength needs as the patient's recovery progresses. This reduces the individuality and efficiency of training. Furthermore, some training devices have complex designs and are difficult to operate, which hinders patients from training independently and limits their practicality. Therefore, the development of a hand training device with a novel structure, excellent adaptability, and the ability to quickly adjust the training load is an urgent issue in meeting the individual rehabilitation needs of stroke patients and improving the convenience and effectiveness of training, and is worthy of widespread use. Summary of the Invention
[0003] The technical problem that the present invention aims to solve is to provide a hand training device for stroke patients that overcomes the above-mentioned drawbacks.
[0004] To solve this problem, the hand training device for stroke patients provided by this invention comprises a grip training shell, an operating space formed inside the shell, and an opening on the side of the shell, which connects the operating space to the outside of the shell. A nut insertion groove is provided on the upper part of the grip training shell, and a nut member is fixed inside the nut insertion groove. A sliding guide tube is provided on the upper wall of the working space and extends downward. An external threaded pipe is threaded onto the nut member, and a bottomed hole is formed inside the external threaded pipe. The lower end of the external threaded pipe passes through the sliding guide pipe and extends into the operating space, and is slidably fitted with the sliding guide pipe. A slide pipe is slidably mounted within the external threaded pipe, and a forging press button is mounted on the upper part of the slide pipe. A compression spring is mounted within the external threaded pipe, and the lower end of the compression spring abuts against the bottom of the external threaded pipe and the upper end abuts against the lower part of the press button. A manual rotation ring is provided at the lower part of the external threaded pipe, and the outer periphery of the ring is exposed to the outside through an opening. Preferably, the manual rotating ring has a friction groove formed on its outer periphery. Preferably, the number of openings provided in the side of the grip training shell is four. The number of the nut fitting grooves is four, and each groove corresponds to the position of the opening. The number of the external threaded pipes is four, which correspond to the positions of the openings respectively. Preferably, the grip training shell is made of a resin material. The grip training shell and the nut member are fixed together by adhesive. Preferably, the shape of the nut fitting groove matches the shape of the nut member, and the nut member is fitted into the nut fitting groove. Preferably, the outer threaded pipe and the manual rotating ring are fixed together by welding. Preferably, the lower edge of the grip training shell is arc-shaped. Preferably, the material of the external threaded pipe is metal.
[0005] This invention provides a hand training device with excellent effectiveness, high adaptability, and practicality, offering significant advantages over conventional technologies. Its main advantages are as follows: The resin grip training shell and the arc-shaped lower edge are lightweight and conform well to the curve of the palm, avoiding the discomfort of pressure caused by prolonged gripping and making it suitable for long-term use by stroke patients. The external threaded tube can be moved up and down along the nut member by rotating the manual rotating ring with friction grooves, and the four external threaded tubes can be independently adjusted to precisely adapt the finger positions to patients with different palm sizes. This allows the fingers to naturally exert force, eliminating the problem of poor adaptability that was previously associated with the device. The training intensity can be adjusted without tools, and the compression spring can be easily replaced by simply pulling out the slide tube, allowing for quick response to multiple training loads according to the recovery stage.The entire device has a modular design, is robustly assembled, and is easy to operate, allowing patients to adjust the position and replace the springs by themselves, improving user independence. The inter-component fitting is highly precise, the sliding guide tube allows smooth movement of the external threaded tube, the threaded connection between the nut and external threaded tube ensures stable positioning, and the metal external threaded tube and high-strength adhesive nut component enhance durability. This training device effectively addresses the problems of lack of hand muscle strength and reduced dexterity in stroke patients, strengthening finger flexion and extension function through repeated pressure movements. Its novel and highly practical structure effectively supports patients' rehabilitation training, making it worthy of widespread adoption. [Brief explanation of the drawings]

[0007] The technical means in the embodiments of the present invention will be described clearly and completely below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, but not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations.
[0008] As shown in the drawings, the hand training device for stroke patients comprises a grip training shell 1, and an operating space 3 is formed inside the shell 1. An opening 2 is provided on the side of the shell 1, and the operating space 3 communicates with the outside of the shell 1 through the opening 2. A nut fitting groove 4 is provided on the top of the grip training shell 1, and a nut member 5 is fixed inside the nut fitting groove 4. A sliding guide tube 6 is provided on the upper wall of the working space 3 and extends downward. An external threaded pipe 7 is threadedly engaged with the nut member 5, and a bottomed hole is formed inside the external threaded pipe 7. The lower end of the external threaded pipe 7 passes through the sliding guide pipe 6 and extends into the working space 3, and is slidably engaged with the sliding guide pipe 6. A slide pipe 8 is provided within the external threaded pipe 7 so as to be slidable up and down, and a forging press button 9 is provided at the top of the slide pipe 8. A compression spring 10 is provided within the external threaded pipe 7, and the lower end of the compression spring 10 abuts against the bottom of the external threaded pipe 7, and the upper end abuts against the lower part of the forging press button 9. A manual rotating ring 11 is provided at the lower part of the external threaded pipe 7 , and the outer periphery thereof is exposed to the outside through the opening 2 . The manual rotating ring 11 has a friction groove formed on its outer periphery. The number of openings 2 provided on the side of the grip training shell 1 is four. The number of the nut fitting grooves 4 is four, which correspond to the positions of the openings 2, respectively. The number of the external threaded pipes 7 is four, which correspond to the positions of the openings 2 respectively. The grip training shell 1 is made of resin. The grip training shell 1 and the nut member 5 are fixed by adhesive. The shape of the nut fitting groove portion 4 matches the shape of the nut member 5 , and the nut member 5 is fitted into the nut fitting groove portion 4 . The external threaded pipe 7 and the manual rotating ring 11 are fixed together by welding. The lower edge of the grip training shell 1 is arc-shaped. The material of the outer threaded pipe 7 is metal.
[0009] Palm-adjustable adjustment: Before use, stroke patients need to adjust the vertical position of the external threaded tube 7 according to the size of their palm. To operate, the patient holds the grip training shell 1 and pinches the manual rotating ring 11 extending from the opening 2 with their fingers. By rotating it clockwise, the external threaded tube 7 moves downward along the thread of the nut member 5. By rotating it counterclockwise, the external threaded tube 7 moves upward. By independently adjusting the four external threaded tubes 7, the position of each training pressure button 9 can be adapted to the pressing angle and distance corresponding to each of the patient's fingers, allowing the five fingers to naturally contact the training pressure buttons 9 and achieving a comfortable grip and precise pressing action. Adjusting the training intensity: If the patient needs to adjust the intensity of the pressure training, they can simply pull the slide tube 8 upward. At this time, the slide tube 8 separates from the external threaded tube 7, exposing the internal compression spring 10. The patient can remove the existing compression spring 10 and replace it with a compression spring 10 with a different elastic modulus. Springs with elastic modulus values ranging from 5 to 20 N / cm are available, and should be selected according to the patient's stage of recovery. After replacement, the slide tube 8 is reinserted into the bottomed hole of the external threaded tube 7, and the compression spring 10 regains its support against the pressure button 9, completing the intensity adjustment. The entire process is simple and requires no tools, meeting the needs of multiple stages of training, from light to intense. Hand training operation: After adjustment, the patient holds the grip training shell 1 in one hand, with each of the five fingers corresponding to one of the four training buttons 9. The thumb can be used with one training button or alternately pressed with the other fingers, depending on the user's comfort. During use, the patient voluntarily presses each finger downward, depressing the training button 9 and compressing the internal compression spring 10. When released, the spring force causes the training button 9 to return to its original position. By repeating this process, the patient can train the flexion and extension strength and dexterity of the fingers. During the training process, the patient can adjust the frequency and depth of pressure according to their own recovery status, gradually improving hand muscle strength and motor function.
[0010] This training device is characterized by its excellent effectiveness, high adaptability, and practicality. The resin grip training shell and the arc-shaped lower edge make it lightweight and conform well to the curves of the palm, avoiding the discomfort of pressure caused by prolonged gripping and making it suitable for long-term use by stroke patients. The external threaded tube can be moved up and down along the nut member by rotating the manually rotating ring with friction grooves. The four external threaded tubes can be independently adjusted to precisely adapt finger position to patients with different palm sizes. This allows the fingers to exert force naturally, eliminating the problem of poor adaptability that was previously associated with the device. The training intensity can be adjusted without tools, and the compression spring can be easily replaced by simply pulling out the slide tube, allowing for quick response to multiple training loads according to the recovery stage.The entire device has a modular design, is robustly assembled, and is easy to operate, allowing patients to adjust the position and replace the springs by themselves, improving user independence. The inter-component fitting is highly precise, the sliding guide tube allows smooth movement of the external threaded tube, the threaded connection between the nut and external threaded tube ensures stable positioning, and the metal external threaded tube and high-strength adhesive nut component enhance durability. This training device effectively addresses the problems of lack of hand muscle strength and reduced dexterity in stroke patients, strengthening finger flexion and extension function through repeated pressure movements. Its novel and highly practical structure effectively supports patients' rehabilitation training, making it worthy of widespread adoption.
