Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment technology, specifically an upper limb rehabilitation training equipment for cerebral infarction. Background Technology

[0002] Cerebral infarction, a sudden brain disease, can occur at any age. The degree of necrosis varies depending on the location and size of the thrombus. Current cerebral infarction patients undergo upper limb rehabilitation training during rehabilitation. Main rehabilitation training is a scientific and individualized treatment method that restores the patient's physical function through various means and helps the patient achieve the goal of rehabilitation. Different rehabilitation training methods have different advantages and disadvantages, and the appropriate method needs to be selected according to the patient's condition and the doctor's opinion. Corresponding rehabilitation training equipment is required in the rehabilitation training process.

[0003] A search revealed Chinese patent number CN215585387U, which discloses an upper limb rehabilitation training device. The device includes: a top plate with two symmetrical telescopic rods fixedly connected to its bottom surface; a U-shaped rod placed at the bottom of the top plate, with each end of the U-shaped rod hinged to the outer surface of one of the telescopic rods; a first elastic element installed at the bottom of the outer surface of the U-shaped rod; and two symmetrical adjustment mechanisms installed inside the top plate. Through the coordinated arrangement of the top plate, pull ropes, second elastic elements, and handles, the patient can perform training by gripping the handles with both hands and pulling back and forth in a coordinated manner with both arms; that is, moving one handle downwards causes the other handle to move upwards.

[0004] While this training method can help patients with upper limb motor rehabilitation to some extent, its training pattern is relatively singular and cannot adapt to different patients. Furthermore, the training intensity varies depending on the patient's recovery stage, making it unsuitable for the varying needs of patients at different stages. Inadequate training hinders effective rehabilitation, significantly reducing the efficiency of upper limb rehabilitation training. Therefore, existing upper limb rehabilitation trainers have significant limitations in terms of adaptability and rehabilitation efficiency, necessitating a new upper limb rehabilitation trainer for stroke patients to meet their rehabilitation needs at different recovery stages.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, an embodiment of the present invention provides an upper limb rehabilitation training device for cerebral infarction, comprising: a base 1;

[0023] The bracket 2 is slidably installed on the top of the base 1. An installation plate 3 is installed between the two sides of the inner wall of the bracket 2. Two second auxiliary wheels 6 are symmetrically distributed and fixedly installed at the bottom of the installation plate 3. A connecting rope 7 is placed between the two second auxiliary wheels 6. Pull rings 8 are fixedly installed at both ends of the connecting rope 7.

[0024] The slide plate 9 is slidably mounted on the top of the base 1. Two fixed plates 10 are symmetrically distributed and fixedly mounted on the top of the slide plate 9. A rotating rod 11 is rotatably mounted between the two fixed plates 10. Two pull plates 12 are symmetrically distributed and fixedly mounted on the outer surface of the rotating rod 11. A positioning plate 13 is fixedly mounted on the outer surface of the rotating rod 11. Multiple return springs 14 are fixedly mounted between the positioning plate 13 and the slide plate 9.

[0025] A movable component 15 is mounted on the base 1 and is used to move the support 2 and the slide plate 9 to change positions.

[0026] When patients are undergoing rehabilitation training, they first select appropriate training equipment based on their own recovery status. The support 2 can move flexibly on the top of the base 1 through its sliding installation structure, and the slide plate 9 also has a sliding function. The positions of the two can be adjusted according to training needs. The moving component 15, as a key component, can drive the support 2 and the slide plate 9 to change positions, thereby realizing the rapid switching between different training equipment and meeting the diverse needs of patients for training intensity and methods at different recovery stages.

[0027] When patients need to perform traction training, the pull rings 8 on the connecting rope 7 can be used as training handles. After holding the pull rings 8 with both hands, the patient can pull the connecting rope 7 to make the two second auxiliary wheels 6 roll at the bottom of the mounting plate 3, thereby driving the movement of the connecting rope 7. The patient can hold the pull rings 8 with both hands and pull back and forth in coordination with both arms, that is, moving one end of the handle downwards will drive the other end of the handle upwards, and perform back and forth training to activate the upper limb muscles. This is the basic rehabilitation training for patients with cerebral palsy. The next stage of rehabilitation training will require the training structure on the skateboard 9. At this time, the support 2 and the skateboard 9 can be adjusted and switched to a suitable position through the moving component 15. At this time, the patient can manually pull the pull plate 12 without changing the position, which will drive the rotating rod 11 to rotate, thereby driving the positioning plate 13 to squeeze the reset spring 14. The rebound force generated by the squeezed reset spring 14, combined with the patient's repetitive pulling force, can increase the training intensity of the patient's upper limb strength, thereby further enhancing the training effect.

[0028] With the flexible operation of the movable component 15, patients can easily switch between different training equipment to achieve a gradual transition from low intensity to high intensity and from simple movements to complex movements. This diversified design can not only meet the needs of patients for training intensity and methods at different recovery stages, but also effectively improve the pertinence and efficiency of rehabilitation training and promote the rapid recovery of patients' upper limb function.

[0029] like Figure 1 As shown, in some embodiments, an electric push rod 4 is fixedly inserted into the mounting plate 3, and a first auxiliary wheel 5 is fixedly installed on the telescopic end of the electric push rod 4. The first auxiliary wheel 5 is in contact with the connecting rope 7.

[0030] The electric push rod 4 is activated, which drives the first auxiliary wheel 5 to move down, thereby pressing down the connecting rope 7. This makes it easier to lift the pull rings 8 at both ends of the connecting rope 7, raising its height to accommodate people of different heights and needs. Both hands can comfortably pull the pull rings 8.

[0031] like Figure 4 As shown, in some embodiments, the moving component 15 includes a gear 151 rotatably mounted on the bottom of the base 1, a drive motor 152 for driving the gear 151 to rotate is fixedly mounted on the bottom of the base 1, and two straight toothed plates 153 are slidably mounted on the bottom of the base 1, both straight toothed plates 153 meshing with the gear 151, and the two straight toothed plates 153 are respectively fixedly connected to the bracket 2 and the slide plate 9.

[0032] Starting the drive motor 152 can drive the gear 151 to rotate in both directions, which in turn can drive the two oppositely arranged straight toothed plates 153 to slide relative to each other. Moving the position of the two straight toothed plates 153 can drive the support 2 and the slide plate 9 to move and change their position, so that the training equipment can automatically move to the patient's side for training without the patient moving, which provides convenience for the patient.

[0033] like Figure 3 As shown, in some embodiments, a seat 16 is fixedly installed on the top of the base 1, an electric telescopic rod 17 is fixedly installed on one side of the seat 16, a limiting plate 18 is slidably installed on the seat 16, and the telescopic end of the electric telescopic rod 17 is fixedly connected to one side of the limiting plate 18.

[0034] The patient sits upright in seat 16. Activating the electric telescopic rod 17 retracts its telescopic end, causing the limiting plate 18 to move downwards. This blocks and limits the patient's frontal position, preventing the patient from potentially falling forward and causing an accident during training. This provides a certain degree of protection for the patient.

[0035] like Figure 1As shown, in some embodiments, two third auxiliary wheels 19 are symmetrically distributed and fixedly installed on the bracket 2. Counterweights 20 are slidably installed on both sides of the bracket 2. A fixing rope 201 is fixedly installed between the mounting plate 3 and the counterweights 20. Placement plates 21 for placing the counterweights 20 are fixedly installed on both sides of the bracket 2. An iron block 22 is detachably installed at the bottom of the counterweights 20. Fixing members 23 for fixing the counterweights 20 are installed on the bracket 2.

[0036] For further intensive training of the patient, the fixation of the fixing piece 23 to the counterweight 20 can be released. Then the patient can pull the two pull rings 8 with both hands at the same time to move the mounting plate 3, the fixing rope 201 and the counterweight 20. Through the gravity of the three, the patient's upper limb muscles can be further strengthened. Iron blocks 22 of different weights can be installed on the counterweight 20 to increase the intensity of the training.

[0037] like Figure 2 As shown, in some embodiments, the bottom end of the counterweight 20 is provided with a slot, and the top of the iron block 22 is fixedly installed with a locking plate 24, which is engaged in the slot.

[0038] The card plate 24 is tightly engaged in the slot. Simply pull the iron block 22 to remove the card plate 24 from the slot, and the iron block 22 can be released for replacement.

[0039] like Figure 2 As shown, in some embodiments, the fastener 23 includes a U-shaped plate 231, and slots are constructed on both the counterweight 20 and the bracket 2, with the two ends of the U-shaped plate 231 being tightly inserted into the two slots respectively.

[0040] When it is necessary to release the counterweight 20, simply pull the U-shaped plate 231 to move its two ends out of the two slots. Its simple structure makes it easy for patients with cerebral palsy to operate and use.

[0041] like Figure 1 As shown, in some embodiments, an anti-slip rubber pad 25 is fixedly installed on the inner circumference of the pull ring 8.

[0042] The anti-slip rubber pad 25 is used to increase the friction of the pull ring 8, making it easier for the patient to grip the pull ring 8.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
