Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a hand rehabilitation training device for stroke patients. Background Technology

[0002] Stroke, also known as apoplexy or cerebrovascular accident, is an acute cerebrovascular disease characterized by high incidence, high disability rate, and high mortality rate. Many stroke patients experience hand motor dysfunction after the onset of the disease, such as finger weakness, decreased grip strength, and loss of finger dexterity, which seriously affects their daily living self-care ability and quality of life. Therefore, hand rehabilitation training is crucial for the rehabilitation of stroke patients, and hand rehabilitation training devices are needed at this time.

[0003] Existing hand rehabilitation training devices are usually rehabilitation gloves or grip balls. For stroke patients, the problem is not only insufficient grip strength, but more importantly, a lack of hand-eye coordination. Hand-eye coordination training is one of the core components of hand rehabilitation for stroke patients, and its importance is no less than that of grip strength training. However, rehabilitation gloves or grip balls can only achieve rehabilitation training for the patient's grip strength and flexion, completely ignoring the rehabilitation needs of three-dimensional spatial positioning ability. Therefore, the rehabilitation training effect of the device is relatively singular. In view of this, we propose a hand rehabilitation training device for stroke patients. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a hand rehabilitation training device for stroke patients, so as to solve the technical problem that the current hand rehabilitation training devices have a relatively limited effect on the hand rehabilitation of stroke patients.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a hand rehabilitation training device for stroke patients, including a training table, a driving structure arranged on one side of the training table, a disc arranged on the driving structure, the disc located on one side of the top of the training table, a circular groove arranged around the top of the disc, and two sets of rectangular grooves arranged on the other side of the top of the training table, one set of rectangular grooves containing rehabilitation gloves and the other set of rectangular grooves containing training balls;

[0006] The drive structure includes a power structure, a transmission structure, and a sleeve structure. The power structure and the sleeve structure are arranged inside the training platform. The disk is arranged on the sleeve structure, and the transmission structure is arranged between the power structure and the sleeve structure.

[0007] Preferably, there are six groups of training balls inside the rectangular groove, and the diameters of the six groups of training balls decrease sequentially. There are also six groups of placement grooves arranged around the disk, and the diameters of the six placement grooves correspond to the diameters of the six groups of training balls.

[0008] Preferably, the power structure includes a support and a bracket, the support is arranged inside the training platform, a motor is arranged on the top of the support, and a first gear is arranged on the rotating shaft at the output end of the motor.

[0009] Preferably, the support is arranged inside the training table, a second gear is rotatably arranged at the top of the support, a round rod is horizontally arranged through the support, the round rod passes through the center of the second gear, and the second gear meshes with the first gear.

[0010] Preferably, the surface of the round rod is symmetrically arranged with limiting grooves, the inner hole of the second gear is arranged with limiting blocks corresponding to the limiting grooves, and the limiting blocks are located in the limiting grooves. The two sides of the second gear are symmetrically arranged with concentric mounting sleeves, and the mounting sleeves are rotatably connected to the inner wall of the bracket.

[0011] Preferably, the sleeve structure includes a sleeve and a mounting rod. The sleeve is arranged inside the training platform, and the mounting rod is sleeved on the sleeve. The mounting rod passes through the top of the training platform and connects to the center of the bottom of the disc.

[0012] Preferably, the conductive structure includes an L-shaped connecting frame, a ball, and a connecting seat. The top end of the vertical section of the L-shaped connecting frame is connected to one end of the limiting groove. The ball is arranged at one end of the horizontal section of the L-shaped connecting frame. The ball is rolled inside one end of the connecting seat. The connecting seat is arranged at the bottom end of one side of the mounting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through its designed drive structure, disc, and training ball, allows stroke patients to undergo hand rehabilitation training. The patient wears rehabilitation gloves, and the person grasps the training ball. During this process, the person's fingers need to bend, and with the aid of the rehabilitation gloves, the patient's grip strength and flexion are trained. Simultaneously, the person can drive the disc to rotate slowly via the drive structure. After grasping the training ball, the person places it into the placement groove of the slowly rotating disc, thus completing the training of the patient's hand-eye coordination. Therefore, the entire process simultaneously achieves the synchronous training effect of the patient's hand grip strength, finger flexion, and hand-eye coordination. This allows the device to achieve diverse training effects for the patient's hand rehabilitation, solving the technical problem that current hand rehabilitation training devices for stroke patients have relatively limited effectiveness. Therefore, this utility model has the advantage of diverse training effects.

[0015] 2. The driving structure of this utility model is composed of a power structure, a transmission structure, and a sleeve structure. Therefore, when the driving structure is working, the round rod in the power structure drives the L-shaped connecting frame in the transmission structure to rotate. Because the round rod can slide freely on the support, the L-shaped connecting frame, in conjunction with the ball in the connecting seat, can drive the sleeve in the sleeve structure to reciprocate along the mounting rod to a certain extent. At the same time, the sleeve will also reciprocate up and down on the mounting rod. Therefore, it can drive the disc to reciprocate while simultaneously reciprocating up and down, thereby enabling the synchronous transformation of the placement groove in the horizontal and vertical positions, realizing the dynamic change of the placement groove in three-dimensional space (horizontal + vertical), strengthening the training of depth perception and motion trajectory prediction ability in hand-eye coordination, and further improving the effect of hand-eye coordination training.

[0024] like Figures 1 to 6As shown, this utility model relates to a hand rehabilitation training device for stroke patients, including a training table 1. A drive structure 2 is arranged on one side of the training table 1, and a disc 3 is arranged on the drive structure 2. The disc 3 is located on one side of the top of the training table 1. A circular groove 301 is arranged around the top of the disc 3. Two sets of rectangular grooves 4 are arranged on the other side of the top of the training table 1. A rehabilitation glove 5 is placed inside one set of rectangular grooves 4 (it should be noted that the rehabilitation glove 5 is prior art and will not be described in detail here). A training ball 6 is placed inside the other set of rectangular grooves 4.

[0025] When performing hand rehabilitation training for stroke patients, the patient can wear rehabilitation gloves 5, and then the person grasps the training ball 6. During this process, the person's fingers need to bend, and with the help of rehabilitation gloves 5, the patient's grip strength and bending degree are trained. At the same time, the person can drive the disc 3 to rotate slowly through the drive structure 2. After the person grasps the training ball 6, the training ball 6 is placed into the placement groove 301 of the slowly rotating disc 3. At this time, the patient's hand-eye coordination ability is trained. Therefore, the entire process simultaneously achieves the synchronous training effect of the patient's hand grip strength, finger bending degree and hand-eye coordination ability, so that the device can achieve a variety of training effects for the patient's hand rehabilitation.

[0026] Specifically, there are six sets of training balls 6 inside the rectangular groove 4, with the diameter of the six sets of training balls 6 decreasing sequentially. There are also six sets of placement grooves 301 arranged around the disc 3, with the diameter of the six sets of placement grooves 301 corresponding to the diameter of the six sets of training balls 6. By grasping training balls 6 of different diameters, the patient's fingers bend and grip to different degrees, so that when the person wearing rehabilitation gloves 5 grasps the training balls 6, they can better train their hand grip strength and bending degree. Moreover, placing training balls 6 of different diameters into the corresponding placement grooves 301 can achieve better hand-eye coordination training results.

[0027] In this embodiment of the invention, the drive structure 2 includes a power structure 7, a transmission structure 8, and a sleeve structure 9. The power structure 7 and the sleeve structure 9 are arranged inside the training platform 1. The disc 3 is arranged on the sleeve structure 9, and the transmission structure 8 is arranged between the power structure 7 and the sleeve structure 9. The power structure 7 includes a support 701 and a bracket 704. The support 701 is arranged inside the training platform 1, and a motor 702 is arranged on the top of the support 701. A first gear 703 is arranged on the rotating shaft at the output end of the motor 702. The bracket 704 is arranged inside the training platform 1. A second gear 706 is rotatably arranged on the top of the bracket 704. A round rod 705 is horizontally arranged inside the bracket 704 and passes through the center of the second gear 706. The second gear 706 meshes with the first gear 703. Limiting grooves 707 are symmetrically arranged on the surface of the round rod 705. The inner hole is provided with a limiting block 708 corresponding to the limiting groove 707, and the limiting block 708 is located in the limiting groove 707. The second gear 706 is symmetrically arranged with concentric mounting sleeves 709 on both sides, and the mounting sleeves 709 are rotatably connected to the inner wall of the bracket 704. The sleeve structure 9 includes a sleeve 901 and a mounting rod 902. The sleeve 901 is arranged in the training table 1, and the mounting rod 902 is sleeved on the sleeve 901. The mounting rod 902 passes through the top of the training table 1 and is connected to the bottom center of the disc 3. The transmission structure 8 includes an L-shaped connecting frame 801, a ball 802 and a connecting seat 803. The top of the vertical section of the L-shaped connecting frame 801 is connected to one end of the limiting groove 707. The ball 802 is arranged at one end of the horizontal section of the L-shaped connecting frame 801. The ball 802 is rolled in one end of the connecting seat 803. The connecting seat 803 is arranged at the bottom end of one side of the mounting rod 902.

[0028] When the drive structure 2 is working, the motor 702 drives the second gear 706 to rotate through the first gear 703. Then, with the cooperation of the limiting groove 707 and the limiting block 708, the second gear 706 can drive the round rod 705 to rotate. The round rod 705 can then drive the L-shaped connecting frame 801 to rotate. Since the round rod 705 can slide freely on the bracket 704, during the rotation of the L-shaped connecting frame 801, in conjunction with the ball 802 in the connecting seat 803, the sleeve 902 can be driven to reciprocate along the mounting rod 901 to a certain extent. At the same time, the sleeve 902 will also reciprocate up and down on the mounting rod 901. Therefore, while driving the disc 3 to reciprocate, it can also reciprocate up and down at the same time. This allows for the synchronous transformation of the placement groove 301 in the horizontal and vertical positions, realizing the dynamic change of the placement groove 301 in three-dimensional space (horizontal + vertical). This strengthens the training of depth perception and motion trajectory prediction ability in hand-eye coordination, and further improves the effect of hand-eye coordination training.

[0029] Working principle: This embodiment provides a hand rehabilitation training device for stroke patients. First,

[0030] When performing hand rehabilitation training for stroke patients, the patient can wear rehabilitation gloves 5, and then the person grasps the training ball 6. During this process, the person's fingers need to bend, and with the help of rehabilitation gloves 5, the patient's grip strength and bending degree are trained. At the same time, the person can drive the disc 3 to rotate slowly through the drive structure 2. After the person grasps the training ball 6, the training ball 6 is placed into the placement groove 301 of the slowly rotating disc 3. At this time, the patient's hand-eye coordination ability is trained. Therefore, the entire process simultaneously completes the synchronous training effect of the patient's hand grip strength, finger bending degree and hand-eye coordination ability, so that the device can achieve a variety of training effects for the patient's hand rehabilitation.

[0031] Secondly, when grasping training balls 6 of different diameters, the patient's fingers need to bend and grip to different degrees, so that when the person wearing rehabilitation gloves 5 grasps the training balls 6, the grip strength and bending degree of the hand can be better trained. Moreover, placing training balls 6 of different diameters into the corresponding placement grooves 301 can achieve better hand-eye coordination training effect.

[0032] Finally, when the drive structure 2 is working, the motor 702 drives the second gear 706 to rotate through the first gear 703. Then, with the cooperation of the limiting groove 707 and the limiting block 708, the second gear 706 can drive the round rod 705 to rotate. The round rod 705 can then drive the L-shaped connecting frame 801 to rotate. Since the round rod 705 can slide freely on the bracket 704, during the rotation of the L-shaped connecting frame 801, in conjunction with the ball 802 in the connecting seat 803, the sleeve 902 can be driven to reciprocate along the mounting rod 901 to a certain extent. At the same time, the sleeve 902 will also reciprocate up and down on the mounting rod 901. Therefore, while driving the disc 3 to reciprocate, it can also reciprocate up and down at the same time. This allows for the synchronous transformation of the placement groove 301 in the horizontal and vertical positions, realizing the dynamic change of the placement groove 301 in three-dimensional space (horizontal + vertical). This strengthens the training of depth perception and motion trajectory prediction abilities in hand-eye coordination, further improving the effect of hand-eye coordination training.
