Description

Technical Field

[0001] The present invention relates to the field of rehabilitation training, in particular to a rehabilitation training institution for stroke patients. Background Art

[0002] Hand function plays a crucial role in daily life and work, especially fine motor skills of the fingers, which are directly related to a patient's self-care ability and quality of life. For patients with stroke, nerve damage, traumatic hand injuries, and other neuromuscular disorders, finger dysfunction is a critical issue that needs to be addressed during rehabilitation. While existing rehabilitation training equipment can improve overall hand function to a certain extent, it still has many shortcomings when it comes to rehabilitation training for individual finger joints, especially the phalangeal units.

[0003] Currently available hand rehabilitation training devices primarily focus on overall gripping, stretching, or large-scale flexion and extension training. Common training equipment primarily focuses on overall palm traction, wrist flexion and extension, or hand grip training, lacking structural designs for refined, segmented, and quantitative training of individual finger joints. This holistic training approach can trigger compensatory movements in the early stages of rehabilitation, resulting in some joints not receiving adequate exercise and others being overloaded. This is not only detrimental to the full recovery of the small muscle groups in the hand, but can also easily lead to poor training results and prolonged rehabilitation cycles due to the single training method. Improper training can even induce complications such as finger stiffness, contractures, and adhesions, further impacting the patient's subsequent recovery of fine motor skills.

[0004] Especially in the middle and late stages of rehabilitation, patients typically require systematic, targeted functional training for muscle groups such as finger flexors, extensors, and abductors, as well as coordination, flexibility, and endurance between the phalanges. However, existing technologies lack training mechanisms that can synchronize and independently activate each phalangeal unit while applying appropriate loads. This results in insufficient muscle activation and inadequate joint flexibility training during rehabilitation training, impacting training effectiveness and the effective reconstruction of neuromuscular pathways.

[0005] Therefore, there is an urgent need to provide a finger rehabilitation training device with a reasonable structure, strong training targeting, controllable load, and the ability to adapt to the needs of different stages of rehabilitation in stages, so as to better improve the recovery effect of fine finger functions, shorten the rehabilitation cycle, and help patients return to normal life as soon as possible.

[0006] Therefore, to address the above issues, rehabilitation training institutions are provided for stroke patients. Summary of the Invention

[0007] In order to solve the problem that there is a lack of a training mechanism that can synchronously drive each finger joint unit to move independently and apply a moderate load, resulting in insufficient muscle activation and inadequate joint flexibility training during rehabilitation training, affecting the training effect and the effective reconstruction of neuromuscular pathways, the present invention provides a rehabilitation training mechanism for stroke patients.

[0008] The present invention solves the above technical problems through the following technical solutions:

[0009] The present invention provides a rehabilitation training mechanism for stroke patients, comprising a base plate and a support frame fixed to the bottom of the base plate, a placement plate for placing palms fixed on the surface of the base plate located at the bottom of the support frame, and a support platform for supporting arms fixed on one side of the support platform;

[0010] A load pulling assembly is provided on the load carrier, the load pulling assembly includes a plurality of load training units, the load training units include knuckle rings connected to the fingers and a load portion with an adjustable load size;

[0011] The knuckle ring is worn on the knuckle, and is transmission-connected to a load-bearing part capable of adjusting the load direction, so that the knuckle ring overcomes the resistance of the load-bearing part and moves.

[0012] In this technical solution, the load-bearing part includes a guide plate, which is connected to the carrier frame through a mounting part, and the bottom of the guide plate is fixedly connected to a rotatable static guide wheel and two symmetrically arranged arc-shaped guide rails;

[0013] A rotatable movable guide wheel, with both sides of the movable guide wheel slidably connected between the two guide rails via sliders, and a locking member is provided on the movable guide wheel to lock its position on the guide rail;

[0014] An elastic load rope, one end of which is connected to a fixed portion on the guide plate, and the other end of which is passed through the top of the static guide wheel and the top of the dynamic guide wheel in sequence and connected to the knuckle ring.

[0015] The knuckle ring is annular in structure and includes a semicircular hard part and a semicircular soft part, wherein the hard part is rotatably connected to the end of the load rope;

[0016] The soft part and the hard part are fixedly connected to form a complete annular structure.

[0017] The mounting portion includes a connecting seat, and a surface and a bottom of the connecting seat are respectively connected to the supporting frame and the guide plate.

[0018] The load-bearing frame and the load-training unit are connected to each other via a connecting portion.

[0019] The number of load exercise units is preferably five to correspond to five fingers.

[0020] The bottom of the connecting seat is a disc-shaped structure, and a ring-shaped sliding groove is opened on the outer wall of the ring. The interior of the sliding groove is slidably connected to a connecting block, and the connecting block is fixed on the bearing plate;

[0021] The top of the connecting seat passes through the supporting frame and the connecting frame on the supporting frame and extends to the top of the connecting frame;

[0022] A limiting column is fixed on the top of the connecting seat, and a rotation limiting portion is provided around the limiting column, and the limiting portion is fixed on the connecting frame.

[0023] By sliding the connecting block in the sliding groove, the entire load exercise unit has the ability to rotate, thereby changing the angle of the load exercise unit to meet the needs of exercising multiple fingers at the same time.

[0024] The limiting part includes a mounting ring, which is fixed on the connecting frame and is sleeved on the surface of the limiting column and is arranged concentrically with the limiting column. A threaded sleeve is fixed on the mounting ring, and a threaded rod is inserted into the internal thread of the threaded sleeve. The end of the threaded rod passes through the mounting ring and is connected to the fixed shaft. The fixed shaft can overlap with the surface of the limiting column.

[0025] The guide plate rotates and the connecting block slides inside the sliding groove to adjust the angle of the load training unit until the load training unit and the finger are in the same vertical plane. Then the threaded rod is rotated so that the fixed shaft on the end of the threaded rod hits the limit column, thereby fixing the load training unit so that it no longer rotates.

[0026] A placement platform for supporting the palm of a corresponding hand is provided on the upper surface of the placement plate on one side close to the load pulling assembly, and the top of the placement platform is a spherical structure.

[0027] By providing a raised platform, patients can naturally place their palms on the raised area during training, allowing their fingers to hang in the air or be slightly bent in a naturally relaxed state. This conforms to the physiological curve of the hand and the relaxed position of the joints, effectively avoiding the muscle tension and joint stress caused by laying the palm flat or overextending the fingers. This design helps to train the range of motion of each finger joint, muscle strength, and coordination, while reducing the burden on the palm, improving training comfort and tolerance. It is particularly suitable for fine motor training and long-term continuous rehabilitation training.

[0028] It also includes a driving component that drives the placement table to rotate. The driving component is arranged inside the mounting shell and the protective shell at the bottom of the placement plate. The mounting shell is fixed to the bottom of the placement plate, and the protective shell is fixed to the bottom of the mounting shell and is connected to the inner cavity of the mounting shell.

[0029] The drive assembly includes a motor, a drive shaft arranged vertically is fixed to the output end of the motor, and the drive shaft extends into the inner cavity of the mounting shell;

[0030] The first driving wheel is fixed on the driving shaft, and the driving shaft is connected to the first driven wheel through a belt drive. The first driven wheel is fixed on the transmission rod, and the transmission rod is installed on the inner wall of the mounting shell. The top of the transmission rod passes through the mounting shell and the placement plate and is connected to the bottom of the placement table.

[0031] The motor drives the first driving wheel to rotate via the driving shaft, and the first driving wheel drives the first driven wheel and the transmission rod to rotate via the belt transmission, thereby driving the placement table to rotate.

[0032] The rotating placement table can further soothe the palms placed on its surface to alleviate the discomfort caused by exercising the fingers.

[0033] The invention also includes a soothing airflow component that is transmission-connected to the driving component, wherein the soothing airflow component includes an air supply portion that is connected to the driving component via a transmission member;

[0034] The driving component drives the air supply unit to operate through the transmission parts, generating airflow, which blows to the exercise area, accelerating the air circulation in the exercise area, thereby increasing local cooling and ventilation to a certain extent, and alleviating local heating, sweating, and fatigue during training.

[0035] A heating unit can be added to the air supply part to heat the air flow generated by the air supply part so that it blows out hot air, which is convenient for rehabilitation personnel to exercise in a low-temperature environment.

[0036] The air supply unit includes a circular mounting shaft, and a plurality of fan blades distributed in a circular array are fixed on the annular surface of the mounting shaft;

[0037] The mounting axis is tilted toward one side of the load pulling assembly to generate an oblique upward airflow;

[0038] The transmission member includes a second driving wheel, which is sleeved and fixed on the driving shaft. The second driving wheel is connected to the second driven wheel through a belt drive. The second driven wheel is fixed on a vertically arranged transmission shaft. The transmission shaft is installed on the inner wall of the mounting shell. A first bevel gear is fixed on the end of the transmission shaft. One side of the first bevel gear is meshed with the second bevel gear. The second bevel gear is connected to one end of the universal joint through a connecting rod at the center of its circle, and the other end of the universal joint is connected to the connecting shaft.

[0039] The change of transmission direction is achieved through the universal joint.

[0040] The diameter of the first driving wheel is smaller than the diameter of the first transmission wheel.

[0041] The diameter of the second driving wheel is larger than the diameter of the second transmission wheel.

[0042] By changing the transmission ratio, the motor can rotate at a lower speed, making the air supply unit rotate at a higher speed to generate sufficient airflow, but the rotation speed of the placement table will not be too high, so as to avoid the placement table rotating at too high a speed, causing discomfort to the rehabilitation person.

[0043] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0044] The positive progress effect of the present invention is:

[0045] The present invention provides a knuckle ring in the finger training device so that the load part can be directly connected to the corresponding knuckle or the middle surface of the knuckle through the knuckle ring. When the patient is training, the load part moves synchronously with the flexion, extension, abduction and adduction of the fingers, so that each knuckle unit can participate in the force and movement during the training process. Through this design, it is possible to not only exercise the strength of the finger flexors, extensors, abductors and other muscle groups, and strengthen the muscle tension and endurance of the small muscle groups of the fingers, but also effectively improve the coordination control ability, range of motion and flexibility of the joints between the knuckles. Compared with the single training method of most existing rehabilitation training equipment that only performs overall traction or simple stretching on the palm or wrist, the present invention can act more specifically on the independent joints of the fingers and the surrounding soft tissues, effectively preventing the occurrence of finger joint contracture, stiffness, adhesion and disuse dysfunction.

[0046] In addition, due to the precision of the training movements and the controllability of the load, patients can implement corresponding training in stages during the early, middle and late stages of rehabilitation. This not only improves the safety and comfort of training and reduces the risk of excessive stretching or injury, but also promotes the reconstruction of neuromuscular pathways and the strengthening of motor nerve feedback loops through continuous and balanced functional training, thereby accelerating the recovery of finger function and the reconstruction of daily living ability, and helping patients to recover fine operation capabilities in a shorter time, such as grasping, writing, buttoning and other functional movements, so that they can better return to normal life and work scenes.

[0069] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0070] like Figure 1 and Figure 2 As shown, the rehabilitation training mechanism for stroke patients includes a base plate 1 and a support frame 11 fixed to the bottom of the base plate 1. A placement plate 3 for placing palms is fixed on the surface of the base plate 1 at the bottom of the support frame 11, and a support platform for supporting arms is fixed on one side of the support platform 12;

[0071] A load pulling assembly 2, the load pulling assembly 2 being arranged on the carrier 11, the load pulling assembly 2 comprising a plurality of load training units, the load training units comprising knuckle rings 27 connected to the fingers and a load portion with an adjustable load size;

[0072] The knuckle ring 27 is worn on the knuckle, and the knuckle ring 27 is transmission-connected to a load-bearing part capable of adjusting the load direction, and the knuckle ring 27 overcomes the resistance of the load-bearing part and moves.

[0073] By connecting the knuckle ring 27 to the corresponding knuckle or the middle surface of the knuckle, the finger drives the load part connected to the knuckle ring 27 to move, that is, the finger is bent and adducted as uniformly as possible on the side of the palm, and then returns to the original position at a uniform speed to perform the exercise, thereby exercising the muscles of the finger knuckle and the flexibility of the knuckle, thereby achieving a better exercise effect on the finger. Compared with general rehabilitation training equipment, it can effectively perform rehabilitation training for the flexibility of the finger, so that the patient can improve the condition faster and return to normal life faster.

[0074] Example 1

[0075] like Figure 7-9As shown, the load-bearing portion includes a guide plate 21, which is connected to the carrier frame 11 through a mounting portion 28. The bottom of the guide plate 21 is fixedly connected to a rotatable static guide wheel 24 and two symmetrically arranged arc-shaped guide rails 22;

[0076] A rotatable movable guide wheel 23, with two sides of the movable guide wheel 23 slidably connected between the two guide rails 22 via sliders 231, and a locking member is provided on the movable guide wheel 23 to lock its position on the guide rail 22;

[0077] An elastic load rope 26 has one end connected to the fixing portion 25 on the guide plate 21 , and the other end passes through the top of the static guide wheel 24 and the top of the dynamic guide wheel 23 in sequence and is connected to the knuckle ring 27 .

[0078] The dynamic guide wheel 23 slides on the arc-shaped guide rail 22, thereby adjusting the position of the dynamic guide wheel 23 in the vertical and horizontal directions, and then the dynamic guide wheel 23 is fixed at the specified position of the guide rail 22 through the locking member, and then the load rope 26 passes through the dynamic guide wheel 23 and the static guide wheel 24 in turn to form the fulcrum a and the fulcrum b. Figure 14 shown.

[0079] Place your palm on the placement plate 3, and insert the corresponding finger knuckles into the knuckle rings 27. The angle between the load rope 26 and the horizontal direction after passing through the fulcrum b is c. By adjusting the position of the fulcrum b and the size of the angle c, when the exercised finger is placed naturally, the angle between it and the traction rope is closest to 90°. When the finger bends inward, it can better feel the resistance brought by the load, so as to achieve a better exercise effect and avoid inefficient exercise.

[0080] The movable guide wheel 23 rotates between the two sliders 231 .

[0081] Specifically, the knuckle ring 27 is an annular structure, and includes a semicircular hard part 271 and a semicircular soft part 272 , and the hard part 271 is rotatably connected to the end of the load rope 26 ;

[0082] The soft component 272 and the hard component 271 are fixedly connected to form a complete annular structure.

[0083] Except for the thumb, the knuckle ring 27 is sleeved between two knuckles of the fingers or on the fingertips, and the soft part 272 of the knuckle ring 27 is in contact with the inner side of the finger.

[0084] In this technical solution, the guide rail 22 is a plate-like structure, and an arc-shaped slide groove is opened on the guide rail 22. The slider 231 slides through the slide groove. Ear plates are fixed on both sides of the slider 231. The ear plates are attached to the surface of the guide rail 22. The slider 231 is slidably connected to the slide groove through the ear plates.

[0085] The locking member is provided on the ear plate, and the locking member is a limiting screw 232. The end of the limiting screw 232 passes through the ear plate and rests on the guide rail 22, and is threadedly connected to the ear plate. The limiting screw 232 is perpendicular to the ear plate.

[0086] The limiting screw 232 is rotated, and the limiting screw 232 is pushed against the guide rail 22 by the pushing action of the thread, thereby fixing the movable guide wheel 23.

[0087] The fixing portion 25 is a fixing plate, a guide wheel or a winding wheel.

[0088] When the fixing portion 25 is a fixing plate, the fixing plate is fixed to the bottom of the guide plate 21 and fixedly connected to the end of the load rope 26 .

[0089] When the fixing portion 25 is a guide wheel, the guide wheel is fixed to the bottom of the guide plate 21 , and the end of the load rope 26 passes over the end of the guide wheel and is hooked to the heavy object.

[0090] In the above embodiment, the load is borne by both the elasticity of the load rope 26 itself and the load weight.

[0091] When the fixed portion 25 is a winding wheel, it is also connected to the bottom of the guide plate 21, and the end of the load rope 26 is fixed on the surface, and the load rope 26 is wound up. The winding wheel is connected to a ratchet pawl structure that can be released in the prior art to prevent it from rotating during exercise.

[0092] By rotating the reel, the effective length of the load rope 26 during exercise can be changed to change the resistance overcome during exercise. The adjusted reel stops rotating through the ratchet pawl structure. At the same time, a structure similar to a locking member can be used to fix the hand wheel so that it no longer rotates. That is, the thread of the screw is self-locking to achieve a locking and fixing effect.

[0093] like Figure 7 As shown, the mounting portion 28 includes a connecting seat 281 , and the surface and bottom of the connecting seat 281 are connected to the supporting frame 11 and the guide plate 21 respectively.

[0094] The carrier frame 11 and the load training unit are connected to each other via a connecting portion.

[0095] The number of load exercise units is preferably five to correspond to five fingers.

[0096] like Figure 13 As shown, the bottom of the connecting seat 281 is a disc-shaped structure, and a ring-shaped sliding groove is opened on the outer wall of the ring. The interior of the sliding groove is slidably connected to the connecting block 282, and the connecting block 282 is fixed on the bearing plate;

[0097] The top of the connecting seat 281 passes through the supporting frame 11 and the connecting frame 13 on the supporting frame 11 and extends to the top of the connecting frame 13;

[0098] The limiting post 283 is fixed on the top of the connecting seat 281 . A rotation limiting portion is provided around the limiting post 283 , and the limiting portion is fixed on the connecting frame 13 .

[0099] By sliding the connecting block 282 in the sliding groove, the entire load exercise unit has the ability to rotate, thereby changing the angle of the load exercise unit to meet the needs of exercising multiple fingers at the same time.

[0100] like Figure 7 and 13 As shown, the limiting portion includes a mounting ring 284, which is fixed on the connecting frame 13, and the mounting ring 284 is sleeved on the surface of the limiting column 283 and is concentrically arranged with the limiting column 283. A threaded sleeve 285 is fixed on the mounting ring 284, and the internal thread of the threaded sleeve 285 is inserted with a threaded rod 286. The end of the threaded rod 286 passes through the mounting ring 284 and is connected to the fixed shaft 287. The fixed shaft 287 can overlap with the surface of the limiting column 283.

[0101] The guide plate 21 rotates, and the connecting block 282 slides inside the sliding groove to adjust the angle of the load training unit until the load training unit and the finger are on the same vertical plane. Then the threaded rod 286 is rotated so that the fixed shaft 287 on the end of the threaded rod 286 reaches the limit column 283, thereby fixing the load training unit so that it no longer rotates.

[0102] Example 2

[0103] like Figure 1 As shown, a placement platform 5 for supporting the palm of a hand is provided on the upper surface of the placement plate 3 close to the load pulling assembly 2 , and the top of the placement platform 5 is a spherical structure.

[0104] By providing a raised placement platform 5, the patient can naturally place their palm on the raised area during training, allowing the fingers to be suspended or slightly bent in a naturally relaxed state, which conforms to the physiological curve of the hand and the relaxed position of the joints. This effectively avoids muscle tension and joint stress caused by lying flat on the palm or overextending the fingers. This design helps to train the range of motion of each finger joint, muscle strength, and coordination, while reducing the burden on the palm, improving training comfort and tolerance. It is particularly suitable for fine motor training and long-term continuous rehabilitation training.

[0105] like Figure 11 and 12As shown, it also includes a driving component 6 that drives the placement table 5 to rotate. The driving component 6 is arranged inside the mounting shell 31 and the protective shell 32 at the bottom of the placement plate 3. The mounting shell 31 is fixed to the bottom of the placement plate 3, and the protective shell 32 is fixed to the bottom of the mounting shell 31 and is communicated with the inner cavity of the mounting shell 31.

[0106] The drive assembly 6 includes a motor 61, and a vertically arranged drive shaft 611 is fixed to the output end of the motor 61. The drive shaft 611 extends into the inner cavity of the mounting shell 31;

[0107] The first driving wheel 62 is fixed on the driving shaft 611, and the driving shaft 611 is connected to the first driven wheel 63 through a belt drive. The first driven wheel 63 is fixed on the transmission rod 64, and the transmission rod 64 is installed on the inner wall of the mounting shell 31. The top of the transmission rod 64 passes through the mounting shell 31 and the placement plate 3 and is connected to the bottom of the placement table 5.

[0108] The motor 61 drives the first driving wheel 62 to rotate via the driving shaft 611 , and the first driving wheel 62 drives the first driven wheel 63 and the transmission rod 64 to rotate via the belt transmission, thereby driving the placement table 5 to rotate.

[0109] The rotatable platform 5 provides continuous and gentle support and cushioning for the patient's palm during finger training. When the patient's palm is placed on the platform 5 for fine motor training such as finger flexion and extension, abduction, and pinching, the platform 5 rotates and rubs the palm, thereby reducing the shear force, friction, and localized pressure on the palm caused by independent finger movement. This effectively alleviates fatigue, soreness, and discomfort in the palm during training. The drive assembly 6 can be activated during breaks in exercise to relieve fatigue and discomfort during rest periods.

[0110] Furthermore, it also includes a soothing airflow component 7 that is transmission-connected to the driving component 6, and the soothing airflow component 7 includes an air supply portion 71, and the air supply portion 71 is connected to the driving component 6 through a transmission member;

[0111] The driving component 6 drives the air supply part 71 to operate through the transmission part, generating airflow, which blows to the exercise area, accelerating the air circulation in the exercise area, thereby increasing local cooling and ventilation to a certain extent, and alleviating local heating, sweating, and fatigue during training.

[0112] A heating unit may be added to the air supply portion 71 to heat the air flow generated by the air supply portion 71 so that hot air is blown out, thereby facilitating rehabilitation personnel to exercise in a low-temperature environment.

[0113] The air supply portion 71 includes a circular mounting shaft, and a plurality of fan blades distributed in a circular array are fixed on the annular surface of the mounting shaft;

[0114] The mounting axis is tilted toward one side of the load traction assembly 2 to generate an oblique upward airflow;

[0115] The transmission member includes a second driving wheel 65, which is sleeved and fixed on the driving shaft 611. The second driving wheel 65 is connected to the second driven wheel 66 through a belt drive. The second driven wheel 66 is fixed on a vertically arranged transmission shaft 661. The transmission shaft 661 is installed on the inner wall of the mounting shell 31. A first bevel gear 67 is fixed on the end of the transmission shaft 661. One side of the first bevel gear 67 is meshed with a second bevel gear 68. The second bevel gear 68 is connected to one end of the universal joint 73 through a connecting rod at the center of its circle, and the other end of the universal joint 73 is connected to the connecting shaft 72.

[0116] The change of the transmission direction is achieved by means of the universal joint 73 .

[0117] The diameter of the first driving wheel 62 is smaller than the diameter of the first transmission wheel.

[0118] The diameter of the second driving wheel 65 is larger than the diameter of the second transmission wheel.

[0119] By changing the transmission ratio, the motor 61 rotates at a lower speed, so that the air supply unit 71 rotates at a higher speed to generate sufficient airflow, but the speed of the placement table 5 will not be too high, thereby avoiding excessive speed of the placement table 5 causing discomfort to the rehabilitation patient.

[0120] The present invention is not limited to the above-described embodiments. Any changes in shape or structure fall within the scope of protection of the present invention. The scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention. Such changes and modifications shall fall within the scope of protection of the present invention.
