Description

Technical Field

[0001] The present invention belongs to the field of hand rehabilitation training, and particularly relates to a hand rehabilitation training device for the rehabilitation medicine department. Background Art

[0002] In the rehabilitation medicine department, hand rehabilitation training is crucial for patients with hand injuries, strokes, or neurological diseases to restore hand function;

[0003] However, the existing hand rehabilitation training devices have relatively single functions and can only provide simple flexion and extension training, unable to fully meet the complex movement rehabilitation needs of the hand; for example, some devices cannot take into account the targeted training of finger spreading and bending movements, making it difficult to achieve multi-dimensional strength and flexibility exercises;

[0004] At the same time, the existing devices perform poorly in adapting to individual differences among different patients. Since the hand strength and finger lengths of different patients vary, and most devices cannot flexibly adjust the training intensity and adapt to different finger sizes, the rehabilitation training effect is greatly reduced;

[0005] In addition, for patients with severely damaged hand functions who have difficulty independently completing training movements, the existing training devices often lack effective auxiliary driving means, making it difficult for these patients to obtain sufficient rehabilitation training. Therefore, a hand rehabilitation training device for the rehabilitation medicine department is needed to solve the above problems. Summary of the Invention

[0006] The purpose of the embodiments of the present invention is to provide a hand rehabilitation training device for the rehabilitation medicine department to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A hand rehabilitation training device for the rehabilitation medicine department includes a support assembly, a plurality of first connectors, four first training assemblies, a second training assembly, and a plurality of second connectors. The support assembly is rotatably connected to the four first training assemblies and a second training assembly respectively through the plurality of first connectors, and the plurality of second connectors are respectively arranged in the four first training assemblies and a second training assembly;

[0009] The support assembly includes a support plate, and a through groove is opened on one side of the support plate;

[0010] The first connector includes a first connecting rod, a rotating block is connected to the outside of the first connecting rod, a plurality of first connecting rods are rotatably connected in the support plate, a first torsion spring is sleeved outside the first connecting rod, and two ends of the first torsion spring are respectively connected to the through groove and the rotating block;

[0011] The first training component includes a first adjusting member, a second adjusting member, a third adjusting member, and three first finger sleeves;

[0012] The second training component includes a fourth adjusting member, a fifth adjusting member, and two second finger sleeves.

[0013] In a further technical solution, a fixing member is connected to the other side of the support plate.

[0014] In a further technical solution, the three first finger sleeves are respectively connected to the bottoms of the first adjusting member, the second adjusting member, and the third adjusting member.

[0015] In a further technical solution, the two second finger sleeves are respectively connected to the bottoms of the fourth adjusting member and the fifth adjusting member.

[0016] In a further technical solution, one end of the rotating block is connected to the first connecting rod, the other end of the rotating block is rotatably connected to the second connecting rod, one ends of the first adjusting member, the second adjusting member, and the fourth adjusting member are connected to the second rotating rod, one ends of the first adjusting member, the second adjusting member, and the fourth adjusting member are rotatably connected to the second rotating rod, one end of the third adjusting member disposed inside the second adjusting member is connected to the second connecting rod, and one end of the fifth adjusting member disposed inside the fourth adjusting member is connected to the second connecting rod.

[0017] In a further technical solution, two ends of the second torsion spring are respectively connected to two ends of the rotating block and the first adjusting member, the first adjusting member and the second adjusting member, the second adjusting member and the third adjusting member, the rotating block and the fourth adjusting member, and the fourth adjusting member and the fifth adjusting member.

[0018] In a further technical solution, the first adjusting member, the second adjusting member, the third adjusting member, the fourth adjusting member, and the fifth adjusting member can be set as fixed rods with different lengths according to actual situations, or can be set as adjusting rods with adjustable lengths.

[0019] In a further technical solution, the torques of the first torsion spring and the second torsion spring can be adjusted according to actual situations.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In the present invention, through a unique structural design, it is possible to simultaneously realize the training of finger extension and bending. When the patient respectively puts the fingers into the first finger sleeve and the second finger sleeve, the extension action drives the rotating block to rotate the first connecting rod, overcoming the torque of the first torsion spring to exercise the finger extension force; during the bending action, each adjusting member cooperates to drive the second connecting rod to rotate, causing multiple second torsion springs to be twisted, so that each finger overcomes the corresponding torque during the bending process, realizing targeted bending force training, thereby comprehensively improving the hand rehabilitation training effect;

[0022] In the present invention, the first adjusting member, the second adjusting member, the third adjusting member, the fourth adjusting member, and the fifth adjusting member can be set as fixed rods of different lengths or adjustable adjusting rods, which is convenient for adjusting according to the actual length of the patient's finger and improves the use comfort. At the same time, the torsion forces of the first torsion spring and the second torsion spring can be replaced and adjusted according to the strength of the patient's hand, ensuring that the training intensity is suitable for different patients, greatly enhancing the adaptability of the device to different individuals, and guaranteeing the effectiveness of the rehabilitation training.

[0023] In the present invention, for patients whose hand functions are severely damaged and who cannot independently complete training actions, a flexible solution is provided. By connecting a plurality of first connecting rods and a plurality of second connecting rods to an external motor, the motor can control the rotation of the first rotating rod or the second rotating rod, thereby driving the fingers to spread or bend, realizing the rehabilitation training of the hand fingers, and providing the possibility for this part of special patients to obtain sufficient rehabilitation training.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] The following describes the specific implementation of the present invention in detail in combination with specific embodiments.

[0032] Embodiment 1

[0033] As Figures 1-4 shown, the embodiment of the present invention provides a hand rehabilitation training device for the department of rehabilitation medicine, including a support assembly 1, a plurality of first connecting members 2, four first training assemblies 3, a second training assembly 4 and a plurality of second connecting members 5. The support assembly 1 is rotatably connected to the four first training assemblies 3 and a second training assembly 4 respectively through the plurality of first connecting members 2, and the plurality of second connecting members 5 are respectively arranged in the four first training assemblies 3 and a second training assembly 4;

[0034] The support assembly 1 includes a support plate 101, and a through groove 102 is formed on one side of the support plate 101;

[0035] The first connecting member 2 includes a first connecting rod 201, a rotating block 202 is connected to the outside of the first connecting rod 201. The plurality of first connecting rods 201 are all rotatably connected in the support plate 101, and a first torsion spring 203 is sleeved outside the first connecting rod 201. The two ends of the first torsion spring 203 are respectively connected to the through groove 102 and the rotating block 202;

[0036] The first training assembly 3 includes a first adjusting member 301, a second adjusting member 302, a third adjusting member 303 and three first finger sleeves 304;

[0037] The second training assembly 4 includes a fourth adjusting member 401, a fifth adjusting member 402 and two second finger sleeves 403.

[0038] In this embodiment, when the index finger, middle finger, ring finger and little finger are respectively inserted into the first finger sleeves 304 and the thumb is inserted into the second finger sleeve 403, the spreading action of the five fingers will drive the rotating block 202, and then cause the first connecting rod 201 to rotate in the support plate 101; at the same time, the rotation of the rotating block 202 causes the first torsion spring 203 to generate a torsional deformation; during this process, the fingers need to overcome the torsion of the first torsion spring 203 to complete the spreading action, so as to realize the rehabilitative strength training of the fingers;

[0039] When the index finger, middle finger, ring finger, and little finger inserted into the first finger sleeve 304 are bent, the respective adjusting members work together. The first adjusting member 301 drives the second connecting rod 501 to rotate within the rotating block 202 and also drives the second connecting rod 501 to rotate within itself; the third adjusting member 303 drives the second connecting rod 501 to rotate within the second adjusting member 302; the fourth adjusting member 401 drives the second connecting rod 501 to rotate again within the rotating block 202; the fifth adjusting member 402 drives the second connecting rod 501 to rotate within the fourth adjusting member 401. During these rotation processes, the rotation of the second connecting rod 501 causes multiple second torsion springs 502 to be distorted; therefore, during the bending process of each finger, the torsion of multiple second torsion springs 502 needs to be overcome; by repeatedly performing the bending action, each finger can receive targeted rehabilitative strength training;

[0040] As Figure 1 shown, specifically, a fixing member 6 is connected to the other side of the support plate 101.

[0041] In this embodiment, the fixing member 6 can be set as a magic tape that can be adhered together. The fixing member 6 can be fixed on the wrist of the user, and then the support plate 101 is fixed on the back of the hand through the fixing member 6.

[0042] As Figures 1-3 shown, specifically, the three first finger sleeves 304 are respectively connected to the bottoms of the first adjusting member 301, the second adjusting member 302, and the third adjusting member 303.

[0043] In this embodiment, after the index finger, middle finger, ring finger, and little finger are respectively inserted into the first finger sleeve 304 and the index finger, middle finger, ring finger, and little finger are bent around the joints, the bent index finger, middle finger, ring finger, and little finger can drive the first adjusting member 301, the second adjusting member 302, and the third adjusting member 303 to rotate around the second connecting rod 501.

[0044] As Figures 1-3 shown, specifically, the two second finger sleeves 403 are respectively connected to the bottoms of the fourth adjusting member 401 and the fifth adjusting member 402.

[0045] In this embodiment, after the thumb is inserted into the second finger sleeve 403 and the thumb is bent around the joint, the bent thumb can drive the fourth adjusting member 401 and the fifth adjusting member 402 to rotate around the second connecting rod 501.

[0046] As Figures 1-4As shown, specifically, one end of the rotating block 202 is connected to the first connecting rod 201, and the other end of the rotating block 202 is rotatably connected to the second connecting rod 501. One ends of the first adjusting member 301, the second adjusting member 302, and the fourth adjusting member 401 are connected to the second rotating rod, and the other ends of the first adjusting member 301, the second adjusting member 302, and the fourth adjusting member 401 are rotatably connected to the second rotating rod. One end of the third adjusting member 303 disposed inside the second adjusting member 302 is connected to the second connecting rod 501, and one end of the fifth adjusting member 402 disposed inside the fourth adjusting member 401 is connected to the second connecting rod 501.

[0047] In this embodiment, the second connecting rod 501 can rotatably connect the first adjusting member 301 and the rotating block 202, the second adjusting member 302 and the first adjusting member 301, the third adjusting member 303 and the second adjusting member 302, the fourth adjusting member 401 and the rotating block 202, and the fifth adjusting member 402 and the fourth adjusting member 401 together.

[0048] As Figures 1-4 shown, specifically, both ends of the second torsion spring 502 are respectively connected to both ends of the rotating block 202 and the first adjusting member 301, the first adjusting member 301 and the second adjusting member 302, the second adjusting member 302 and the third adjusting member 303, the rotating block 202 and the fourth adjusting member 401, and the fourth adjusting member 401 and the fifth adjusting member 402.

[0049] In this embodiment, when the user's finger is bent, the bent finger drives the first adjusting member 301, the second adjusting member 302, the third adjusting member 303, the fourth adjusting member 401, or the fifth adjusting member 402 to rotate through the first finger sleeve 304 or the second finger sleeve 403, and the second torsion spring 502 is distorted.

[0050] Embodiment 2

[0051] Please refer to Figures 1-3 , the difference between this embodiment and Embodiment 1 is that a plurality of first connecting rods 201 and a plurality of second connecting rods 501 are connected to an external motor, and the motor can be connected to the corresponding rotating block 202, first adjusting member 301, second adjusting member 302, and fourth adjusting member 401;

[0052] In this embodiment, when the fingers of the user's palm cannot be smoothly extended or bent, a motor can be installed on the first connecting rod 201 or the second connecting rod 501 corresponding to the finger part, and then the first rotating rod or the second rotating rod can be controlled to rotate through the motor. The rotating first rotating rod can drive the finger to extend through the rotating block 202, and the rotating second rotating rod drives the finger to bend through the first adjusting member 301, the second adjusting member 302, the third adjusting member 303, the fourth adjusting member 401, or the fifth adjusting member 402, so that the device can perform rehabilitation training on the fingers of the hand.

[0053] As Figures 1-3 shown, specifically, the first adjusting member 301, the second adjusting member 302, the third adjusting member 303, the fourth adjusting member 401, and the fifth adjusting member 402 can be set as fixed rods of different lengths according to actual situations, or can be set as adjusting rods with adjustable lengths.

[0054] In this embodiment, since the lengths of the fingers of different users and the lengths of multiple fingers of each palm are not consistent, when using this device, it is necessary to adjust the first adjusting member 301, the second adjusting member 302, the third adjusting member 303, the fourth adjusting member 401, and the fifth adjusting member 402 to lengths adapted to each finger, so that different users can comfortably use this device, improving the applicability of this device.

[0055] As Figures 1-3 shown, specifically, the torsional forces of the first torsion spring 203 and the second torsion spring 502 can be adjusted according to actual situations.

[0056] In this embodiment, during the use of this device, multiple first torsion springs 203 and multiple second torsion springs 502 can be replaced with torsion springs of different torsional force magnitudes according to the strength of the user's hand and the strength of each finger of the user, improving the applicability of this device and ensuring the hand rehabilitation training effect of this device for different users.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
