[0002] When a patient's arm is injured, the elbow joint cannot rotate for a long time, which will lead to difficulty in arm movement and even muscle atrophy. At present, there are two main methods of elbow rehabilitation exercise: manual and rehabilitation exercise auxiliary devices. Although the manual method can adopt different rehabilitation exercise methods according to the different conditions of the patient's arm to meet their different needs, so as to avoid long-term hanging and causing atrophy and degeneration of upper limb muscles, it is generally carried out through upper limb training by pulling the handle of the special fracture bed for the arm, but some patients are prone to hand slipping during training, and the body directly leans back on the bed, causing secondary injuries to the patient.

[0028] Further, such as Figure 5-6 As shown, one end of the first rotating plate 36 is rotatably connected to the third fixed seat 35, and the other end of the first rotating plate 36 is rotatably connected to the second fixed seat 34. A push rod 39 is welded and fixed to one end of each bolt 38, and an elastic block 40 is bolted to one end of each push rod 39, and one side of each elastic block 40 is in extrusion contact with the second rotating plate 41.

[0029] Further, such as Figure 5-6 As shown, a second fixed frame 28 is welded and fixed on the other side of the second frame 24, a motor 29 is bolted to one end of the second fixed frame 28, a screw rod 30 is provided at the output end of the motor 29, a moving block 31 is slidably provided inside the second fixed frame 28, the moving block 31 is in contact with the outer thread of the screw rod 30, a push plate 32 is welded and fixed to one side of the moving block 31 toward the second frame 24, the push plate 32 slides inside the second frame 24, and the push plate 32 is in contact with the rear side of the first slider 33.

[0030] Further, such as Figure 3-4 As shown, a rotating shaft 17 is welded and fixed on the lower side of the first frame 11, and the rotating shaft 17 rotates and contacts on the base plate 10. A second slider 25 is welded and fixed on the lower side of the front end of the second frame 24, and an arc-shaped slide groove 26 is provided on the base plate 10, and the second slider 25 slides in the arc-shaped slide groove 26.

[0031] Further, such as Figure 4As shown, two air bags 27 are respectively provided on both sides of the arc-shaped slide groove 26 .

[0032] Further, such as Figure 1 As shown, a plurality of first massage balls 14 are fixedly disposed at intervals on the inner side of the first protective gear 12 , and a plurality of second massage balls 20 are fixedly disposed at intervals on the inner side of the second protective gear 18 .

[0033] Further, such as Figure 1 As shown, a plurality of first bandages 15 are connected to both ends of the first protective gear 12, and a plurality of second bandages 21 are connected to both ends of the second protective gear 18.

[0034] When in use, the patient places the upper arm on the inner side of the first brace 12, and the patient's upper arm is limited and fixed inside the first brace 12 by a plurality of first bandages 15; then, the patient places the forearm on the inner side of the second brace 18, and the patient's forearm is limited and fixed inside the second brace 18 by a plurality of second bandages 21.

[0035] When the patient's arm is actively moving in the vertical direction, the staff fills the two airbags 27 with gas, so that the second slider 25 is limited in the middle of the arc-shaped slide groove 26 by the two airbags 27, so as to prevent the second slider 25 from sliding in the arc-shaped slide groove 26 and affecting the patient's arm's vertical rehabilitation movement. Then, the staff rotates one of the bolts 38, and the bolt 38 is threadedly contacted with the first fixed frame 37 through the bolt 38, so that the bolt 38 moves, and the bolt 38 moves through the push rod 39 to drive the elastic block 40 to move, and the elastic block 40 moves to drive the second rotating plate 41 to rotate, and the second rotating plate 41 rotates to drive the elastic plate 42 to rotate, and the rotation of the elastic plate 42 squeezes the first slider 33 to different degrees; after the second rotating plate 41 rotates, the width of the slider between the second rotating plate and the side wall of the second frame gradually decreases from the rear end to the front end, so that the swing of the second rotating plate 41 is controlled by rotating the corresponding bolt 38, so as to adjust the resistance generated by the first slider 33 in the sliding process in the second frame 24. The movement of the bolts 38 from the back to the front makes the second rotating plate 41 rotate at a smaller and smaller angle, so that the friction resistance of the second rotating plate 41 and the elastic plate 42 to the first sliding block 33 is gradually reduced.

[0036] The patient's arm performs active vertical movement, and the second brace 18 rotates around the rotation point of the first fixed seat 23 and the connecting plate 22, so that the second brace 18 is rotated and lifted, and the rotation and lifting of the second brace 18 drives the third fixed seat 35 to move, and the movement of the third fixed seat 35 drives the second fixed seat 34 to move through the rotation of the first rotating plate 36, and the movement of the second fixed seat 34 drives the first slider 33 to slide in the second frame 24, and the friction contact between the first slider 33 and the elastic plate 42 cooperates with the rotation of the second rotating plate 41, so that the resistance to the sliding of the first slider 33 in the second frame 24 is continuously strengthened, so that the patient's arm can perform active vertical movement, thereby accelerating the recovery time.

[0037] When the patient's arm performs passive vertical movement, the staff rotates the bolts 38 outward, so that the elastic blocks 40 are out of contact with the second rotating plate 41, and the first slider 33 slides in the second frame 24, and the friction resistance between the first slider 33 and the elastic plate 42 is the same; at this time, the motor 29 starts to drive the screw rod 30 to rotate, and the screw rod 30 rotates and contacts with the screw rod 30 thread through the moving block 31, so that the moving block 31 slides in the second fixed frame 28; when the screw rod 30 rotates clockwise to drive the moving block 31 to move forward, the moving block 31 moves through the push plate 32 to drive the first slider 33 to slide in the second fixed frame 28, and the second slider 33 is driven by the push plate 32 to drive the first slider 33 to slide in the second fixed frame 28. A slider 33 moves forward, and the first slider 33 moves forward to drive the third fixed seat 35 to move upward through the second fixed seat 34 and the first rotating plate 36. The third fixed seat 35 moves upward to drive the second brace 18 to be lifted upward around the rotating connection between the connecting plate 22 and the first fixed seat 23; when the screw rod 30 rotates counterclockwise to drive the moving block 31 to move backward, the moving block 31 moves to drive the push plate 32 to move and disengage from the first slider 33, and the second brace 18 is pressed down by the weight of the patient's forearm, so that the second brace 18 moves downward, so that the patient can perform passive rehabilitation exercises.

[0038] When the patient performs horizontal movement, the rotating shaft 17 is first rotated on the first frame 11 to cooperate with the second slider 25 to slide in the arc groove 26, so as to facilitate the horizontal rotation of the patient's arm. Then, the second slider 25 slides in the arc groove 26 to cooperate with the two air bags 27 to squeeze the second slider 25, thereby changing the amount of gas in the air bags 27 to change the degree of resistance to the horizontal movement of the patient's arm. In this way, the multi-angle rotation of the patient's arm is achieved, overcoming the defect that the existing training device can only achieve single-plane rotation. The first massage ball 14 and the second massage ball 20 on the first protective gear 12 and the second protective gear 18 can ensure that the patient's arm is squeezed, thereby increasing the massage function of the training device, accelerating the blood circulation of the patient's arm, and facilitating rehabilitation training.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the appended claims and their equivalents.
