Technical Field

[0001] This invention relates to an upper limb rehabilitation training device for stroke patients, and particularly to an upper limb rehabilitation training device and training method for stroke patients. Background Technology

[0002] Stroke, a disease name in Traditional Chinese Medicine, is divided into external wind and internal wind. External wind is caused by the invasion of external pathogens (wind evil), and is called stroke in the "Treatise on Cold Damage" (also known as Guizhi Tang syndrome). Internal wind belongs to internal injury disease, also known as cerebral apoplexy, stroke, etc. In modern times, the term stroke generally refers to stroke-like internal injury disease, which is mostly caused by qi and blood disorder, cerebral blood vessel obstruction, or blood spillage into the brain. Stroke patients need to exercise frequently during rehabilitation treatment, so rehabilitation training devices are needed.

[0016] As a preferred embodiment of the present invention, both of the pulling training components include concave frames. The upper ends of the two concave frames are fixedly connected to the lower ends of the two L-shaped slides, respectively. The left and right sides of the interior of the two concave frames are fixedly connected to the left and right ends of the two square frames, respectively. The two square frames are movably connected to eight T-shaped rods 7 through four circular holes opened inside their front ends.

The front ends of the eight springs 5 ​​are fixedly connected to the rear ends of the eight finger plates, and the eight springs 5 ​​are divided into two groups of four, with their rear ends fixedly connected to the front ends of the two square frames, respectively. The left and right sides of the interior of the two concave frames are fixedly connected to the left and right ends of the two pull rods, respectively.

[0017] A training method for an upper limb rehabilitation training device for stroke patients includes the following steps:

[0018] a1. When stroke patients use this device to exercise their upper limbs, they first sit on the seat board with their backs pressed against the front of the massage board. At this time, the patient holds two levers with both hands and moves them downwards. With the cooperation of the concave frame, L-shaped slide plate, connecting block, I-shaped rotating block, threaded rod, and horizontal plate, the convex plate can be moved downwards. After the convex plate moves downwards a certain distance, the patient stops applying force to the two levers. At this time, with the cooperation of the second mounting plate, the second spring, and the second T-shaped rod, the convex plate can be reset. By continuously moving the convex plate up and down, the patient's upper limbs can be exercised.

[0019] a2. During the up-and-down movement of the convex plate, the two toothed plates can be moved accordingly. At this time, under the action of the two gears, the two rotating shafts can be rotated. Through the rotation of the two rotating shafts, the two rotating shafts can be rotated through the mutual cooperation between the T-shaped connecting sleeve, bevel gear one and bevel gear two. Through the rotation of the two rotating shafts, the two rotating shafts can be rotated through the mutual cooperation between the push plate, push rod, cam three, T-shaped rod six and spring four. The mounting plate three can be rotated through the reciprocating motion in the front-and-back direction. During the movement of the mounting plate three, the massage effect on the patient's back can be achieved through the mutual cooperation between the T-shaped rod five, massage head and spring three.

[0020] a3. When the device is in use and the position of the two pull rods needs to be adjusted in the front-back direction according to the patient's condition, the two electric hydraulic rods are activated to move the mounting plate two in the front-back direction. Then, with the cooperation of the T-shaped plate three, convex plate, horizontal plate, T-shaped rod two, connecting block and L-shaped slide plate, the two pulling training components can be moved in the front-back direction, thus realizing the adjustment of the position of the two pull rods in the front-back direction. When the patient has difficulty training his upper limbs independently, the patient holds the two pull rods with both hands and then starts the motor one. The rotation of the output shaft of the motor one can drive the cam one to rotate. Then, under the action of the spring two, the convex plate can be moved in the up-down direction. Then, under the action of the pull rods, the patient's arms can be moved to perform flexion and extension exercises, thus achieving the effect of passively driving the patient to train.

[0021] a4. When the distance between the two levers needs to be adjusted according to the patient's needs during use, the two pins are moved upwards so that they are no longer in contact with the two L-shaped slides. At this time, the distance between the two levers can be adjusted by moving the two L-shaped slides inside the two sliding cavities opened inside the connecting block. This makes it convenient for different patients to hold the device. When the patient needs to exercise their fingers, the patient holds the two square frames from above, so that the fingers other than the thumb rest on the front end of the corresponding finger plate. Then, the patient holds both hands tightly and moves the corresponding finger plate backwards by moving the fingers. With the cooperation of the T-shaped lever seven and the spring five, the patient's fingers can be exercised.

[0022] a5. When the position of the device needs to be adjusted during use, start motor two. The rotation of motor two's output shaft, under the action of the worm gear and worm wheel, drives shaft one to rotate. The rotation of shaft one, under the action of cam two, pushes the two mounting plates one downward, thereby driving the four moving wheels to pass through the four through slots opened inside the base until the lower ends of the four moving wheels contact the ground. At this point, the device can be easily moved, thus realizing the adjustment of the device's position. After the device's position is adjusted, start motor two to drive the worm gear to rotate in the opposite direction. Then, with the cooperation of the worm wheel, shaft one, cam two, T-shaped rod one, and spring one, the two mounting plates one can be moved upward, thereby driving the four moving wheels upward. At this point, the lower ends of the four moving wheels are no longer in contact with the ground, ensuring the stability of the device during use.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention utilizes the interaction between the T-shaped rod three, spring two, and mounting plate two to move the convex plate upwards, while simultaneously restricting its direction of movement. Stroke patients can grasp the two levers with both hands and move them downwards. This, in turn, is facilitated by the interaction between the concave frame, L-shaped sliding plate, connecting block, I-shaped rotating block, threaded rod, and horizontal plate, causing the convex plate to move downwards. At this point, the spring two provides exercise for the patient's upper limbs, accelerating recovery. When the patient has difficulty exercising independently, the interaction between the motor one, cam one, T-shaped rod three, and spring two moves the convex plate vertically. This, in turn, is facilitated by the interaction between the connecting block, L-shaped sliding plate, and concave frame, causing the two levers to move vertically, thus enabling the patient to perform flexion and extension exercises for their arms.

[0025] 2. This invention, through the interaction of the toothed plate, gear, and convex plate, enables two rotating shafts to rotate during the exercise of the patient's upper limbs. The rotation of the two rotating shafts, under the action of the T-shaped connecting sleeve, bevel gear one, bevel gear three, and rotating shaft three, drives two cams three to rotate. The rotation of the two cams three, through the interaction of the push plate, push rod, T-shaped rod six, and spring four, drives the mounting plate three to reciprocate in the front-back direction. During the front-back movement of the mounting plate three, the interaction of several T-shaped rods five, spring three, and massage heads achieves a massage effect on the patient's back, allowing the patient to feel relaxed during training.

[0026] 3. The present invention utilizes an electro-hydraulic rod to move the mounting plate two in the front-back direction during use, adapting to different patients. This movement of the mounting plate two, in conjunction with the T-shaped rod three, convex plate, horizontal plate, T-shaped rod two, connecting block, L-shaped sliding plate, and concave frame, drives the two pull rods in the front-back direction, facilitating gripping by different patients. Correspondingly, by moving the two pins upwards, they are no longer in contact with the two L-shaped sliding plates, allowing them to slide left-right. The concave frame then adjusts the distance between the two pull rods, adapting to different patients and enabling flexible adjustments based on individual needs. The T-shaped rod four and vertical plate, in conjunction, restrict the movement direction of the mounting plate two.

[0027] 4. This invention, through the interaction of the threaded rod, the horizontal plate, and the I-shaped rotating block, enables the connecting block to move vertically during use. The movement of the connecting block, in conjunction with the L-shaped sliding plate and the concave frame, drives the two pull rods to move vertically as well, thereby adjusting the height of the two pull rods. Furthermore, the interaction of the square frame, the T-shaped rod, the finger plate, and the spring allows for convenient finger exercises alongside upper limb exercises, increasing the versatility of the exercise program.

[0028] 5. This invention utilizes the interaction between the second motor, worm gear, worm wheel, and first rotating shaft to drive the two second cams to rotate. The rotation of the two second cams, under the action of the first mounting plate, drives the four movable wheels downwards until their lower ends contact the ground. At this point, the device can be moved, facilitating position adjustment. After the device's position is adjusted, the second motor drives the worm gear to rotate in the opposite direction. With the cooperation of the worm wheel, first rotating shaft, second cam, first spring, and first T-shaped rod, the four movable wheels move upwards until the lower end of the base contacts the ground. The base then enhances the stability of the device during use. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figure 1-9As shown, the present invention provides a technical solution: an upper limb rehabilitation training device and training method for stroke patients, including a base 1. A movable component 5 is fixedly connected to the upper end of the base 1. Two fixed posts 2 are fixedly connected to the left and right sides of the upper surface of the base 1. The upper ends of the four fixed posts 2 are fixedly connected to the lower end of the seat plate 6. A back plate 10 is fixedly connected to the rear side of the upper end of the seat plate 6. The back plate 10 is fixedly connected to the front end of a massage component 8 through a square through groove. The front side of the massage component 8 is fixedly connected to the rear end of the back plate 10. The upper end of the massage component 8 engages with the rear side of an adjustment component 9. Two L-shaped plates 11 are fixedly connected to the lower side of the adjustment component 9. Two pulling training components 7 are fixedly connected to the lower front side of the adjustment component 9. The movable component 5 allows the device to be easily moved after use, thus facilitating the adjustment of the device's position. The cooperation between the pulling training components 7 and the adjustment components 9 can provide upper limb rehabilitation training for stroke patients. The exercise enhances the patient's recovery. During upper limb training for stroke patients, the coordinated action of the adjustment component 9 and massage component 8 provides a massage effect on the patient's back, allowing the patient to feel relaxed during training. The L-shaped plate 11 and back plate 10 work together to support the adjustment component 9. A motor 13 is fixedly connected to the upper side of the adjustment component 9, and a cam 12 is fixedly connected to the output shaft of the motor 13. The lower end of the cam 12 overlaps with the upper side of the adjustment component 9. The front ends of the two L-shaped plates 11 are fixedly connected to the rear end of the back plate 10. A battery 3 is installed at the upper end of the base 1, and a control panel 4 is installed on the right side of the upper surface of the seat plate 6. The rotation of the output shaft of the motor 13 drives the cam 12 to rotate. At this time, the coordinated action of the adjustment component 9 and the pulling training component 7 passively drives the patient's upper limbs to train, effectively solving the problem that some patients have difficulty training independently.

[0041] The movable assembly 5 includes a second motor 58, the lower end of which is fixedly connected to the upper end of the base 1. The second motor 58 is fixedly connected to the rear end of a worm gear 59 via an output shaft mounted thereon. The worm gear 59 meshes with a worm wheel 511 for transmission. The worm wheel 511 is fixedly connected to a rotating shaft 56. Cams 55 are fixedly connected to both ends of the rotating shaft 56. The lower ends of the two cams 55 respectively rest on the upper ends of two mounting plates 53. The lower surfaces of the two mounting plates 53 are provided with casters on both the front and rear sides. 51. Both mounting plates 53 are movably connected to four T-shaped rods 52 through two circular holes inside. The lower ends of the four T-shaped rods 52 are fixedly connected to the upper end of the base 1. Springs 54 are sleeved on each of the four T-shaped rods 52. Support plates 57 are movably connected to both sides of the rotating shaft 56. The lower ends of the two support plates 57 are fixedly connected to the upper end of the base 1. Support plate 510 is movably connected to the front end of the worm gear 59. The lower end of support plate 510 is fixedly connected to... At the upper end of the base 1, the rotation of the output shaft of motor 2 58 drives the worm gear 59 to rotate, which in turn drives the rotating shaft 56 to rotate under the action of the worm wheel 511. The rotation of the rotating shaft 56, under the action of the cam 2 55, drives the two mounting plates 53 to move downward, which in turn drives the moving wheels 51 to move downward until the lower ends of all four moving wheels 51 are in contact with the ground. At this point, the device can be easily moved, giving it the characteristic of easy movement. The interaction between the T-shaped rod 52 and the spring 54 not only restricts the movement direction of the mounting plate 53, but also drives the mounting plate 53 to move upward, so that the upper end of the mounting plate 53 can always be in contact with the lower end of the corresponding cam 2 55. The support plate 57 supports the rotating shaft 56, and the support plate 2 510 supports the worm gear 59.

[0042] The adjusting component 9 includes a connecting block 91, which is movably connected to two L-shaped slide plates 92 via sliding cavities on its left and right sides. Each side of the connecting block 91 has a pin 93, which is movably connected to two L-shaped slide plates 92, each with several insertion holes at its upper end. The lower ends of the two L-shaped slide plates 92 are fixedly connected to the upper ends of two pulling training components 7. The connecting block 91 is movably connected to an I-shaped rotating block 919 via a circular hole. The upper end of the I-shaped rotating block 919 is fixedly connected to the lower end of a threaded rod 94. The threaded rod 94 is threadedly connected to a horizontal plate 95 with threaded holes. The horizontal plate 95 is movably connected to two T-shaped rods 96 via two circular holes. The two T-shaped rods 96 are fixedly connected at their lower ends to the upper end of the connecting block 91. The rear end of the connecting block 91 is fixedly connected to the front end of the convex plate 97. Two T-shaped rods 99 are fixedly connected to the upper end of the convex plate 97. Both T-shaped rods 99 are movably connected to the mounting plate 913 with two circular holes in its front end. Springs 98 are fitted onto both T-shaped rods 99. The upper side of the mounting plate 913 is fixedly connected to the lower end of the motor 13. The upper end of the convex plate 97 overlaps with the lower end of the cam 12. By rotating the threaded rod 94, the connecting block 91 can be moved downwards through the interaction of the horizontal plate 95, the T-shaped rods 96, and the I-shaped rotating block 919. Then, the L-shaped sliding plate 92 moves downwards. The pull mechanism moves the two training components 7 downwards, allowing for height adjustment. Pulling the two pins 93 upwards removes them from contact with the two L-shaped slide plates 92, enabling the L-shaped slide plates 92 to slide within the two sliding cavities of the connecting block 91. This adjusts the distance between the two training components 7, accommodating different patients. Pulling the two training components 7 downwards, in conjunction with the L-shaped slide plates 92, connecting block 91, and T-shaped rod 96, moves the horizontal plate 95 and convex plate 97 downwards. At this time, the T-shaped rod 99 and spring 2... The interaction between components 98 generates a pulling force that moves the convex plate 97 and the horizontal plate 95 upwards. This allows for the up-and-down movement of the horizontal plate 95 and the convex plate 97, thus training the patient's upper limbs. When the patient has difficulty training independently, motor 13 drives cam 12 to rotate. This, in turn, with the interaction of the T-shaped rod 99, spring 98, and mounting plate 913, moves the convex plate 97 vertically. At this point, with the interaction of the horizontal plate 95, T-shaped rod 96, connecting block 91, L-shaped slide plate 92, and the pulling training component 7, the patient's upper limbs can undergo flexion and extension training. Two electro-hydraulic rods 915 are fixedly connected to the rear end of mounting plate 913.The rear ends of the two electric hydraulic rods 915 are fixedly connected to the front end of the vertical plate 917. The lower end of the vertical plate 917 is fixedly connected to the upper end of the two L-shaped plates 11. The vertical plate 917 is movably connected to the two T-shaped connecting sleeves 914 through two connecting holes inside. The rear ends of the two T-shaped connecting sleeves 914 are fixedly connected to bevel gears 918. The two bevel gears 918 mesh with the upper end of the massage component 8. The two T-shaped connecting sleeves 914 are movably connected to the two rotating shafts 912, each with two guide blocks, through two guide grooves inside. The two rotating shafts 912 are movably connected to the mounting plate 913, which has two connecting holes inside at the rear end. The front ends of the two rotating shafts 912 are fixedly connected to gears 910. The two gears 910 mesh with two toothed plates 911. The relatively close ends of the two toothed plates 911 are fixedly connected to the left and right ends of the convex plate 97. The vertical plate 917 is movably connected to the two T-shaped connecting sleeves 914 through two guide grooves inside. Two circular holes are respectively connected to two T-shaped rods 916. The front ends of the two T-shaped rods 916 are fixedly connected to the rear end of the mounting plate 913. During the training of the patient's upper limb, the up-and-down movement of the convex plate 97, in conjunction with the toothed plate 911 and gear 910, drives the two rotating shafts 912 to rotate. The rotation of the two rotating shafts 912, in turn, drives the two bevel gears 918 to rotate through the two T-shaped connecting sleeves 914. By activating the two electro-hydraulic rods 915, the mounting plate 913 can be moved forward and backward, thereby driving the two pulling training components 7 to move forward and backward, thus achieving the adjustment of the position of the two pulling training components 7 in the forward and backward direction. The interaction between the T-shaped rods 916 and the vertical plate 917 restricts the movement direction of the mounting plate 913.

[0043] The massage component 8 includes two bevel gears 812. Each bevel gear 812 meshes with one bevel gear 918. The two bevel gears 812 are fixedly connected to the upper ends of two rotating shafts 814. A cam 83 is fixedly connected to the lower end of each rotating shaft 814. The front ends of the two cams 83 are respectively attached to the rear ends of two push plates 82. A push rod 84 is fixedly connected to the front end of each push plate 82. The two push rods 84 are movably connected to two concave frames 81, each with a circular hole at its rear end. The front ends of the two concave frames 81 are fixedly connected to... Attached to the rear end of the back plate 10, the front ends of the two push rods 84 are fixedly connected to the rear end of the mounting plate 3 85. The mounting plate 3 85 is movably connected to several T-shaped rods 5 810 through several circular holes opened inside it. Each of the T-shaped rods 5 810 is fitted with a spring 3 89. Each of the front ends of the T-shaped rods 5 810 is provided with a massage head 811. Each massage head 811 is adapted to a massage plate 88 with several massage holes opened inside it. The massage plate 88 is fixedly connected to the back plate 10 with a square through groove opened inside it. The mounting plate 3 85 is connected to the two T-shaped rods 810 through the limiting holes opened inside it on both its left and right sides. The two T-shaped rods 87 are movably connected, with their front ends fixedly connected to the rear end of the back plate 10. Each of the two T-shaped rods 87 is fitted with a spring 86. Each of the two rotating shafts 814 is movably connected to a support plate 813, the front ends of which are fixedly connected to the rear end of the back plate 10. The rotation of the two bevel gears 918, under the action of the two bevel gears 812, drives the two rotating shafts 814 to rotate. The rotation of the two rotating shafts 814 activates the cam 83, push plate 82, push rod 84, T-shaped rods 87, and spring 86. The interaction between the components allows the mounting plate 3 85 to reciprocate in the front-back direction. Through the reciprocating motion of the mounting plate 3 85, the interaction between the T-shaped rod 5 810 and the massage head 811 enables a massage effect on the patient's back. The interaction between the T-shaped rod 5 810 and the spring 3 89 provides a buffer during the massage, effectively preventing excessive massage force that could cause discomfort to some patients. The T-shaped rod 6 87 restricts the direction of movement of the mounting plate 3 85.

[0044] Both pull training components 7 include concave frames 71. The upper ends of the two concave frames 71 are fixedly connected to the lower ends of the two L-shaped slides 92. The left and right sides of the interior of the two concave frames 71 are fixedly connected to the left and right ends of the two square frames 73. The two square frames 73 are movably connected to eight T-shaped rods 76 through four circular holes opened in their front ends. The front ends of the eight T-shaped rods 76 are fixedly connected to finger plates 74. Springs 75 are sleeved on the eight T-shaped rods 76. The left and right sides of the interior of the two concave frames 71 are fixedly connected to the left and right ends of the two pull rods 72. The patient holds the two pull rods 72 with both hands and pulls them down. At this time, under the action of the concave frames 71, the adjustment component 9 is pulled down, thereby achieving the process of training the upper limb. The patient places their fingers on the corresponding finger plates 74 and then clenches their fingers to move the corresponding finger plates 74 backward. At this time, the interaction between the T-shaped rods 76 and the springs 75 can exercise the patient's fingers.

[0045] The operation steps of this invention are as follows:

[0046] When a stroke patient uses this device to exercise their upper limbs, the patient first sits on the seat 6 with their back pressed against the front of the massage board 88. The patient then holds the two levers 72 with both hands and moves them downwards. The interaction between the concave frame 71, L-shaped slide plate 92, connecting block 91, I-shaped rotating block 919, threaded rod 94, and horizontal plate 95 causes the convex plate 97 to move downwards. After the convex plate 97 has moved downwards a certain distance, the patient stops applying force to the two levers 72. At this point, the interaction between the mounting plate 913, spring 98, and T-shaped rod 96 causes the convex plate 97 to return to its original position. By continuously moving the convex plate 97 up and down, the patient's upper limbs can be exercised.

[0047] During the up-and-down movement of the convex plate 97, the two toothed plates 911 move accordingly. At this time, under the action of the two gears 910, the two rotating shafts 912 rotate. Through the rotation of the two rotating shafts 912, the two rotating shafts 814 rotate. Through the interaction between the T-shaped connecting sleeve 914, bevel gear 918, and bevel gear 812, the two rotating shafts 814 rotate. Through the interaction between the two rotating shafts 814, the push plate 82, push rod 84, cam 83, T-shaped rod 87, and spring 86, the mounting plate 85 reciprocates in the front-and-back direction. During the movement of the mounting plate 85, the massage head 811 and spring 89 work together to achieve a massage effect on the patient's back.

[0048] When the device is in use and the position of the two pull rods 72 needs to be adjusted in the front-back direction according to the patient's condition, the two electric hydraulic rods 915 are activated to drive the mounting plate 913 to move in the front-back direction. Then, with the cooperation of the T-shaped plate 99, convex plate 97, horizontal plate 95, T-shaped rod 96, connecting block 91 and L-shaped slide plate 92, the two pulling training components 7 can be moved in the front-back direction, thereby realizing the adjustment of the position of the two pull rods 72 in the front-back direction. When the patient has difficulty training his / her upper limbs independently, the patient holds the two pull rods 72 with both hands and then starts the motor 13. The rotation of the output shaft of the motor 13 drives the cam 12 to rotate. Then, under the action of the spring 98, the convex plate 97 can be moved in the up-down direction. Then, under the action of the pull rods 72, the patient's arms can be moved to perform flexion and extension exercises, thereby achieving the effect of passively driving the patient to train.

[0049] When the distance between the two levers 72 needs to be adjusted according to the patient's needs during use, the two pins 93 are moved upwards so that they are no longer in contact with the two L-shaped slide plates 92. At this time, the distance between the two levers 72 can be adjusted by moving the two L-shaped slide plates 92 inside the two sliding cavities opened in the connecting block 91. This makes it convenient for different patients to hold the device. When the patient needs to exercise their fingers, the patient holds the two square frames 73 from above, so that the fingers other than the thumb rest on the front end of the corresponding finger plate 74. Then, the patient clenches their hands and moves the corresponding finger plate 74 backwards by moving their fingers. With the cooperation of the T-shaped lever 76 and the spring 75, the patient's fingers can be exercised.

[0050] When the device needs to be adjusted during use, motor 2 58 is started. The rotation of motor 2 58, through the rotation of its output shaft, drives the rotating shaft 56 to rotate under the action of the worm gear 59 and worm wheel 511. The rotation of the rotating shaft 56, under the action of the cam 2 55, pushes the two mounting plates 53 downward, thereby driving the four moving wheels 51 to pass through the four through slots opened inside the base 1 until the lower ends of the four moving wheels 51 contact the ground. At this point, the device can be easily moved, thus realizing the adjustment of the device's position. After the device's position is adjusted, motor 2 58 is started to drive the worm gear 59 to rotate in the opposite direction. Then, through the cooperation of the worm wheel 511, rotating shaft 56, cam 2 55, T-shaped rod 52, and spring 54, the two mounting plates 53 are driven upward, thereby driving the four moving wheels 51 upward. At this point, the lower ends of the four moving wheels 51 are no longer in contact with the ground, ensuring the stability of the device during use.

10. A training method for an upper limb rehabilitation training device for stroke patients according to claim 9, comprising the following steps: a1. When a stroke patient uses this device to exercise his / her upper limbs, the patient first sits on the seat (6) with his / her back close to the front of the massage board (88). At this time, the patient moves downward by holding the two levers (72) with both hands. Then, with the cooperation of the concave frame (71), L-shaped slide (92), connecting block (91), I-shaped rotating block (919), threaded rod (94) and horizontal plate (95), the convex plate (97) can be driven to move downward. After the convex plate (97) moves downward to a certain distance, the patient no longer exerts force on the two levers (72). At this time, with the cooperation of the second mounting plate (913), the second spring (98) and the second T-shaped rod (96), the convex plate (97) can be driven to reset. Then, by continuously moving the convex plate (97) up and down, the effect of exercising the patient's upper limbs can be achieved. a2. During the up-down movement of the convex plate (97), the two toothed plates (911) can be moved accordingly. At this time, under the action of the two gears (910), the two rotating shafts (912) can be rotated. Through the rotation of the two rotating shafts (912), the two rotating shafts (814) can be rotated by the mutual cooperation between the T-shaped connecting sleeve (914), bevel gear one (918) and bevel gear two (812). Through the rotation of the two rotating shafts (814), the two rotating shafts (814) can be rotated by the mutual cooperation between the push plate (82), push rod (84), cam three (83), T-shaped rod six (87) and spring four (86). The mounting plate three (85) can be moved back and forth by the mutual cooperation between the T-shaped rod five (810), massage head (811) and spring three (89). During the movement of the mounting plate three (85), the massage effect on the patient's back can be achieved by the mutual cooperation between the T-shaped rod five (810), massage head (811) and spring three (89). a3. When the device is in use and the position of the two pull rods (72) needs to be adjusted in the front-back direction according to the patient's condition, the two electric hydraulic rods (915) are activated to drive the mounting plate two (913) to move in the front-back direction. Then, with the cooperation of the T-shaped plate three (99), convex plate (97), horizontal plate (95), T-shaped rod two (96), connecting block (91) and L-shaped sliding plate (92), the two pulling training components (7) can be driven to move in the front-back direction, thereby realizing the adjustment of the position of the two pull rods (72). 2) Adjustment process in the front and back direction: When the patient has difficulty training his upper limbs on his own, the patient holds two levers (72) with both hands and starts motor one (13). Motor one (13) can drive cam one (12) to rotate through the rotation of its output shaft. Then, under the action of the set spring two (98), it can drive the convex plate (97) to move in the up and down direction. Then, under the action of the set lever (72), it can drive the patient's arms to flex and extend, thereby achieving the effect of passively driving the patient to train. a4. When the distance between the two levers (72) needs to be adjusted according to the patient's condition during the use of the device, the two pins (93) are moved upward so that they are no longer in contact with the two L-shaped slides (92). At this time, the distance between the two levers (72) can be adjusted by moving the two L-shaped slides (92) inside the two sliding cavities opened in the connecting block (91). This makes it convenient for different patients to hold the device. When the patient needs to exercise their fingers, the patient holds the two square frames (73) from above, so that the fingers other than the thumb are placed on the front end of the corresponding finger plate (74). Then, the patient holds both hands tightly and moves the corresponding finger plate (74) backward by moving the fingers. In this way, the patient's fingers can be exercised by the cooperation between the T-shaped rod seven (76) and the spring five (75). a5. When the position of the device needs to be adjusted during use, start motor two (58). Motor two (58) can drive the rotating shaft one (56) to rotate through the rotation of its output shaft under the action of the worm gear (59) and worm wheel (511). Through the rotation of the rotating shaft one (56), the two mounting plates one (53) can be pushed downward by the action of the cam two (55), which can drive the four moving wheels (51) to pass through the four through slots opened inside the base (1) until the lower ends of the four moving wheels (51) contact the ground. At this time, the device can be adjusted. The device is easily moved to adjust its position. After the position adjustment is completed, the second motor (58) is started to drive the worm (59) to rotate in the opposite direction. Then, with the cooperation of the worm wheel (511), the first rotating shaft (56), the second cam (55), the first T-shaped rod (52), and the first spring (54), the two mounting plates (53) can be moved upward, which in turn can drive the four moving wheels (51) to move upward. At this time, the lower ends of the four moving wheels (51) are no longer in contact with the ground, ensuring the stability of the device during use.
