Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, specifically a hand resistance training device for coronary heart disease rehabilitation and nursing. Background Technology

[0002] During surgery and the recovery period, patients with coronary heart disease experience a significant reduction in limb activity, with the upper limbs remaining in a sedentary state for extended periods. This can easily lead to problems such as stiffness in the hand joints, muscle weakness in the upper limbs, and poor blood circulation. In severe cases, muscle atrophy and incoordination may occur, greatly impacting the patient's daily upper limb mobility and overall rehabilitation outcomes. Therefore, targeted hand resistance training equipment has become an indispensable auxiliary device in the rehabilitation and nursing care of patients with coronary heart disease. It can help patients gradually carry out upper limb rehabilitation training, aiding in the recovery of limb function, and has wide application needs in both clinical rehabilitation and home care scenarios.

[0003] Existing resistance training devices for coronary heart disease hand rehabilitation, through corresponding hand training structures, can provide resistance training for the patient's fingers in grasping motions, thus improving the function of the finger joints and hand muscles to some extent. However, the training structure of these devices is relatively simple, focusing only on training a single finger joint and failing to achieve coordinated training of the wrist, elbow, and finger joints. During training, only local hand muscle groups are activated, making it difficult to improve the overall mobility of the upper limb. Long-term use can easily lead to uneven rehabilitation progress in different parts of the upper limb, resulting in unbalanced limb rehabilitation. Furthermore, the training modes of existing devices are relatively fixed, only suitable for patients with some voluntary upper limb strength for single active training. They are unsuitable for severely rehabilitated patients with severe muscle weakness and poor limb strength, exhibiting poor adaptability and failing to meet the diverse training needs of patients at different rehabilitation stages and with varying limb mobility. Therefore, a hand resistance training device for coronary heart disease rehabilitation nursing is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a hand resistance training device for coronary heart disease rehabilitation nursing, in order to solve the technical problems of limited upper limb rehabilitation and poor adaptability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hand resistance training device for coronary heart disease rehabilitation nursing, comprising a base plate, wherein a hinge lug is connected to the right side of the upper surface of the base plate.

[0006] The hinge ear is movably connected to a linkage arm, the top of the linkage arm is movably connected to a transmission arm, the top of the transmission arm is equipped with a handle, and the handle is equipped with an assembly handle.

[0007] A first spring is inserted inside the assembly handle, a connecting strip is installed on the outer end of the first spring, a finger ring is installed on the outside of the connecting strip, a column is connected to the left side of the upper surface of the substrate, and a sleeve is fitted on the outside of the column.

[0008] The top of the sleeve is equipped with a support plate, and the lower outer side of the sleeve is equipped with a connecting lug. The left end of the transmission arm is movably connected to the inside of the connecting lug. A guide rod is coaxially connected to the top of the inner cavity of the sleeve, and a second spring is sleeved on the outside of the guide rod.

[0009] Preferably, the transmission arm has a right-angle bent arm structure. Damping washers are engaged at the connections between the linkage arm and the transmission arm, the hinge ear, and the hinge between the transmission arm and the hinge ear. This adapts to the overall linkage transmission trajectory of the equipment, ensuring smooth coordinated movement of the multiple arms. The damping washers increase the resistance at the hinge points, preventing the transmission structure from wobbling or loosening, making upper limb training more stable, and improving the overall stability and usability of the training.

[0010] Preferably, there are four sets of the first spring and the finger rings. Each connecting strip is fitted with a ring cap at a position corresponding to the first spring. The two ends of the first spring are connected to the assembly handle and the inner wall of the ring cap, respectively. Multiple sets of finger rings and springs can be adapted to accommodate multiple fingers of the patient for synchronous resistance training, improving the overall uniformity of finger rehabilitation. The ring caps can limit and protect the ends of the springs, preventing spring displacement or detachment under force, ensuring continuous and stable finger resistance training.

[0011] Preferably, the outer circumference of the column is provided with protruding ribs, and the number of protruding ribs is at least three sets. The inner wall of the sleeve is provided with grooves at positions corresponding to the protruding ribs. The protruding ribs and grooves are interlocked and cooperate with each other. Through the interlocking and cooperation of the protruding ribs and grooves, the lifting and lowering movement of the sleeve can be guided and limited, effectively preventing circumferential rotation of the sleeve during operation, ensuring that the sleeve slides vertically and smoothly, avoiding structural jamming problems, and ensuring accurate and smooth linkage training movements.

[0012] Preferably, a limiting plate is installed on the lower outer side of the sleeve. The limiting plate has a fan-shaped structure. A limiting frame is installed on the upper surface of the base plate at a position corresponding to the limiting plate. The top end of the limiting frame has the same shape as the limiting plate and is located on the upper side of the limiting plate. The limiting plate and the limiting frame cooperate with each other to effectively limit the upward stroke of the sleeve, limit the maximum range of motion of the sleeve and the transmission arm, avoid excessive limb movement during patient training, adapt to the gentle rehabilitation training needs of patients with coronary heart disease, and avoid the risks caused by excessive exercise.

[0013] Preferably, the interior of the column is hollow, the interior of the substrate corresponding to the inner cavity of the column is a through hollow structure, the inner wall of the column is threaded, an assembly table is screwed to the lower interior of the column, the assembly table has a through hole, the bottom end of the guide rod is tapered, and the bottom end of the guide rod penetrates the interior of the through hole.

[0014] Preferably, the bottom two sides of the assembly table are connected to transmission frames. A gap is left between the outer surface of the transmission frame and the inner wall of the column. The lower part of the transmission frame is equipped with a lever. The transmission frame and the assembly table can be rotated by the lever, so that the assembly table can be rotated out of the column. This allows the second spring to be replaced, so that the second spring with different elastic force can be replaced for different rehabilitation stages, thus improving the practicality of the equipment.

[0015] Preferably, a flexible pad is installed in the center of the upper surface of the support plate. The flexible pad is M-shaped, and its outer corners are rounded. The M-shaped flexible pad can conform to the patient's arm position, improving the fit and comfort of arm support. The rounded corners eliminate the risk of bumps and bruises from sharp corners, avoiding pressure and scratches on the limbs during training, and are suitable for long-term rehabilitation training.

[0016] Compared with the prior art, the present invention provides a hand resistance training device for coronary heart disease rehabilitation nursing, which has the following beneficial effects:

[0017] This hand resistance training device for coronary heart disease rehabilitation nursing allows patients to pass their fingers through the rings, enabling them to grasp the finger joints for resistance training. Simultaneously, after grasping, the wrist can be moved to pull the swing of the transmission arm, which in turn lowers the sleeve. This allows for synchronous resistance training of the elbow, wrist, and finger joints through reciprocating elbow and wrist flexion after grasping. It can simultaneously activate multiple muscle groups and joints in the upper limb, improve the overall mobility of the patient's upper limb, and avoid the problem of uneven rehabilitation caused by training only one part.

[0018] Simultaneously, the sleeve can be lowered by pressing the arm, which in turn assists in the swinging of the transmission arm. It can be adapted to patients with different upper limb mobility, meeting the active resistance training needs of patients with poor finger movement and insufficient muscle strength, as well as the auxiliary training scenarios of patients with weak limb strength. Through diverse training methods, joint stiffness can be gradually relieved, disused muscle groups can be activated, and blood circulation in the upper limbs can be improved. This avoids problems such as limb degeneration and muscle atrophy caused by long-term rest, thus improving the practicality of the training equipment. Attached Figure Description

[0025] This invention provides a technical solution: a hand resistance training device for coronary heart disease rehabilitation nursing, comprising a base plate 1, a hinge ear 2, a linkage arm 3, a transmission arm 4, a grip 5, a column 6, a protruding ridge 61, a sleeve 7, a groove 71, a support plate 8, a flexible pad 9, an assembly handle 10, a first spring 11, a connecting strip 12, a finger ring 13, a connecting ear 14, a guide rod 15, a second spring 16, an assembly table 17, a through hole 171, a limiting frame 18, a limiting plate 19, a transmission frame 20, and a paddle 201.

[0026] Please see Figure 1 A hinge ear 2 is connected to the right side of the upper surface of the substrate 1. A linkage arm 3 is movably connected inside the hinge ear 2. A transmission arm 4 is movably connected to the top of the linkage arm 3. A handle 5 is installed at the top of the transmission arm 4. Please refer to [link / reference]. Figure 2 The grip 5 has an internal assembly handle 10.

[0027] Please see Figure 3 A first spring 11 is inserted inside the assembly handle 10. A connecting strip 12 is installed on the outer end of the first spring 11. A finger ring 13 is installed on the outside of the connecting strip 12. Please refer to [link / reference]. Figure 1 A column 6 is connected to the left side of the upper surface of the substrate 1, and a sleeve 7 is fitted around the outside of the column 6.

[0028] The top of the sleeve 7 is equipped with a support plate 8, and a flexible pad 9 is installed in the middle of the upper surface of the support plate 8. The flexible pad 9 has an M-shaped structure, and the outer corners of the flexible pad 9 are all rounded. Please refer to [link / reference]. Figure 2A connecting lug 14 is installed on the lower outer side of the sleeve 7. The left end of the transmission arm 4 is movably connected to the inside of the connecting lug 14. Please refer to [link / reference]. Figure 4 The top of the inner cavity of the sleeve 7 is coaxially connected to a guide rod 15, and a second spring 16 is sleeved on the outside of the guide rod 15. By passing the patient's fingers through the finger ring 13, the patient's finger joints can be subjected to resistance training after grasping. At the same time, after grasping, the patient can swing the transmission arm 4 by moving the wrist, which can drive the sleeve 7 to descend. This allows for synchronous resistance training of the elbow, wrist and finger joints through reciprocating elbow flexion and wrist flexion after grasping. This can simultaneously activate multiple muscle groups and joints in the upper limb, improve the overall mobility of the patient's upper limb, and avoid the problem of uneven rehabilitation caused by training of a single part.

[0029] At the same time, the sleeve 7 can be lowered by pressing the arm, which can then assist in the swinging of the transmission arm 4. It can be adapted to patients with different upper limb mobility. It can meet the active resistance training needs of patients with poor finger movement and insufficient muscle strength, and also be adapted to the auxiliary training scenarios of patients with weak limb strength. Through diverse training methods, joint stiffness can be gradually relieved, disused muscle groups can be activated, and blood circulation in the upper limbs can be improved. This can avoid problems such as limb degeneration and muscle atrophy caused by long-term rest, thus improving the practicality of the training equipment.

[0030] Please see Figure 5 The interior of the column 6 is hollow, and the inner wall of the column 6 is threaded. The interior of the base plate 1 is hollow and penetrating, corresponding to the inner cavity of the column 6. An assembly table 17 is screwed to the lower interior of the column 6. The assembly table 17 has a through hole 171. The bottom end of the guide rod 15 is tapered and penetrates the interior of the through hole 171. Both sides of the bottom of the assembly table 17 are connected to transmission frames 20. A gap is left between the outer surface of the transmission frame 20 and the inner wall of the column 6. The lower part of the transmission frame 20 is equipped with a lever 201. The lever 201 drives the rotation of the transmission frame 20 and the assembly table 17, so that the assembly table 17 can be screwed out of the interior of the column 6, thereby allowing the second spring 16 to be replaced. This allows for the replacement of the second spring 16 with different elasticity for different rehabilitation stages, improving the practicality of the equipment.

[0031] The transmission arm 4 is a right-angle bent arm structure. Damping washers are snapped into the connection points of the linkage arm 3 and the transmission arm 4, the hinge ear 2, and the hinge point between the transmission arm 4 and the connecting ear 14. There are four sets of first springs 11 and finger rings 13. Ring caps are installed at the corresponding positions of the connecting bar 12 and the first spring 11. The two ends of the first spring 11 are connected to the inner wall of the assembly handle 10 and the ring cap, respectively. The outer circumference of the column 6 is provided with protruding ribs 61, and there are at least three sets of protruding ribs 61. The inner wall of the sleeve 7 is provided with grooves 71 at the corresponding positions of the protruding ribs 61. The protruding ribs 61 and the grooves 71 are interlocked.

[0032] A limiting plate 19 is installed on the lower outer side of the sleeve 7. The limiting plate 19 has a fan-shaped structure. A limiting frame 18 is installed on the upper surface of the base plate 1 at a position corresponding to the limiting plate 19. The top end of the limiting frame 18 has the same shape as the limiting plate 19 and is located on the upper side of the limiting plate 19.

[0033] This program allows patients to pass their fingers through ring 13, enabling resistance training of the finger joints after grasping. Simultaneously, after grasping, the wrist can be moved to swing the transmission arm 4, which in turn lowers the sleeve 7. This allows for simultaneous resistance training of the elbow, wrist, and finger joints through reciprocating elbow and wrist flexion, simultaneously activating multiple muscle groups and joints in the upper limb. This improves the overall flexibility of the upper limb and avoids the uneven rehabilitation caused by training only one part. The sleeve 7 can also be lowered by pressing the arm, further assisting in the swinging of the transmission arm 4. This system is suitable for patients with varying upper limb mobility, meeting the active resistance training needs of patients with limited finger movement and insufficient muscle strength, as well as the auxiliary training scenarios for patients with weak limb strength. Through diverse training methods, joint stiffness can be gradually relieved, disused muscle groups activated, and upper limb blood circulation improved. This avoids problems such as limb degeneration and muscle atrophy caused by prolonged rest, enhancing the practicality of the training equipment.
