The leg blood circulation exercise device for fracture rehabilitation includes: a bed 1, with a first movable plate 5 and a second movable plate 9 on the top of the bed 1. A second screw 14 and a third screw 17 are rotatably installed inside both the first movable plate 5 and the second movable plate 9. The ends of the second screw 14 and the third screw 17 are fixedly connected to each other. A second servo motor 13 is fixedly installed inside both the first movable plate 5 and the second movable plate 9. The output shafts of the two second servo motors 13 are respectively fixedly connected to one end of the two second screws 14. Movable connecting seats 15 are threaded to the outer sides of both the second screws 14 and the third screws 17. Connecting plates 7 are hinged to both movable connecting seats 15. A common leg support plate 11 is hinged to the end of each connecting plate 7 away from the movable connecting seat 15. Two third fixing plates 20 are fixedly installed on the top of the leg support plate 11. A common foot pedal 6 is rotatably installed on the side of the two third fixing plates 20 that are close to each other. The leg support plate 11 and the foot pedal 6 can better fit the leg and foot.

Multiple second rollers 24 are rotatably installed on the rotating cylinder 23. An electric motor 25 is fixedly installed inside the leg support plate 11. The output shaft of the electric motor 25 is fixedly connected to the rotating cylinder 23. During the rotation of the rotating cylinder 23, the second rollers 24 come into contact with the leg and massage the leg, which can promote blood circulation in the leg, help eliminate swelling and bruising, accelerate the recovery of fracture sites, relax leg muscles, and relieve muscle tension and soreness caused by long-term bed rest or rehabilitation training. A fixed frame 28 and a fixed seat 27 are fixedly installed on the side of the first moving plate 5 and the second moving plate 9 that are close to each other, respectively. A third roller 26 is rotatably installed on the top and bottom of the fixed seat 27, and the outer wall of the third roller 26 is in contact with the inner wall of the fixed frame 28.
[0025] Guide frames 16 are fixedly installed on both sides of the bed body 1. First screws 3 are rotatably installed inside each of the two guide frames 16. First servo motors 2 are fixedly installed on one side of each of the two guide frames 16.

[0031] The working principle of the fracture rehabilitation leg blood circulation exercise device provided by this utility model is as follows:
[0032] First, help the patient onto bed 1 and have them lie down. Place their legs and feet on the leg support 11 and footrest 6 respectively, and then secure them with straps 22. When it is necessary to raise two or one leg, activate one or two second servo motors 13. The output shafts of the second servo motors 13 drive the second screw 14 and the third screw 17 to rotate, causing the two movable connecting seats 15 to move relative to each other. When the two movable connecting seats 15 move relative to each other, they drive the leg support 11 to rise. When the leg support 11 rises, it can precisely conform to the leg. Angle changes provide support, and then two servo motors 2 are activated. The output shaft of the first servo motor 2 drives the first screw 3 to rotate, and the first moving plate 5 and the second moving plate 9 can move, causing the patient's leg to bend and exercise. When it is necessary to exercise only one leg, only one servo motor 2 needs to be activated. After the rehabilitation stage, with the doctor's permission, the motor 25 can be activated. The output shaft of the motor 25 drives the rotating cylinder 23 to rotate, so that the second roller 24 contacts the leg and massages it, promoting blood circulation in the leg and accelerating the rehabilitation process.
