Description

Technical Field

[0001] This utility model relates to the field of foot drop exercise technology, and in particular to an exercise device for preventing foot drop. Background Technology

[0002] Foot drop is one of the signs in orthopedic surgery. It is a common sequela of hemiplegia and stroke. The main symptom is that the ankle cannot be actively flexed and extended, which makes the patient's walking function impaired. When walking, the patient will land on the toes first, which makes the patient walk unsteadily and makes the patient prone to falling.

[0003] For the aforementioned patients, an exercise device is typically used to assist in ankle rotation. During the exercise, to prevent the leg support frame from slipping, a leg support frame is installed at the top of the exercise device for positioning. This leg support frame is usually secured with Velcro. However, during ankle rotation exercises, it's impossible to ensure there are no other objects around the patient's legs. Therefore, during the exercise, the edges of the Velcro are constantly rubbed, causing them to lift. When the edges lift excessively, the load-bearing capacity of the Velcro weakens, affecting the stability of the leg support frame. This can lead to the leg support frame slipping, creating a gap between the bottom of the leg support frame and the patient's foot, affecting the effectiveness of foot drop exercises and slowing down the patient's recovery.

[0004] In response to the above situation, we propose an exercise device to prevent foot drop. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an exercise device to prevent foot drop.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An exercise device for preventing foot drop includes a foot pad, a soft pad fixedly connected to the top outer surface of the leg support frame, a fixing strap fixedly connected to one side of the soft pad, and a fixing snap fixedly connected to the side of the soft pad away from the fixing strap.

[0008] An upper connecting plate is fixedly connected to the top end of the tail end of the fixed connecting strip, and a lower connecting plate is fixedly connected to the bottom end of the tail end of the fixed connecting strip.

[0009] The upper connecting plate and the lower connecting plate are rotatably connected to a rotating rod inside, and a movable connecting belt is fixedly connected to the outer surface of the rotating rod. A second fixing ring is fixedly connected to the tail end of the movable connecting belt.

[0010] The upper connecting plate has an internal mounting cavity. The upper end of the rotating rod extends through the upper connecting plate into the mounting cavity and is fixedly connected to a worm wheel on its end face. The upper surface of the worm wheel is rotatably connected to the inner wall of the mounting cavity. The tooth block of the worm wheel near the fixed connecting belt meshes with a worm.

[0011] The bottom end of the worm gear is rotatably connected to the inner wall of the mounting cavity, and the top end of the worm gear passes through the upper connecting plate and is fixedly connected to a rotating disk on its end face.

[0012] Preferably, a fixing rod is fixedly connected to the top of the foot pad, and both ends of the fixing rod are rotatably connected to the inner wall of the bottom of the leg support frame. A hydraulic cylinder is rotatably connected to the outer surface of the leg support frame below the soft pad, and a fixing plate is rotatably connected to the output end of the hydraulic cylinder. One end of the fixing plate is fixedly connected to the outer surface of the fixing rod on the side away from the foot pad.

[0013] Preferably, a barbed hook and loop fastener is fixedly connected to the outer surface of the foot pad near the fixing connecting strap, and a rough hook and loop fastener is fixedly connected to the outer surface of the foot pad away from the fixing connecting strap. A toe positioning ring is fixedly connected to the front outer surface of the rough hook and loop fastener.

[0014] Preferably, a first fixing ring is fixedly connected to the outer surface of the leg support frame located below the soft pad, and a fixing Velcro is fixedly connected to the outer surface of the leg support frame corresponding to the first fixing ring.

[0015] Preferably, the inner wall curve of the leg support frame conforms to the curve of the patient's leg.

[0016] Preferably, a rigid fixing plate is fixedly connected to the outer surface of the soft pad, and a soft pad is fixedly connected to the inner wall of the soft pad.

[0017] The present invention provides an exercise device for preventing foot drop, which has the following advantages: When worn, the user rotates the rotating disc, causing the rotating rod to rotate as well. This causes the movable connecting strap to wrap around the outer surface of the rotating rod. Simultaneously, the meshing between the worm gear and the worm provides positioning, ensuring that the lengths of the fixed and movable connecting straps do not change with the patient's movements. Furthermore, the fasteners remain in place during patient movement and will not loosen due to friction at the edges. This allows the fixed and movable connecting straps to be better positioned on the patient's leg, preventing the leg support frame from falling downwards during ankle rotation exercises. This results in a tighter fit between the patient's foot and the footpad, leading to a more significant improvement in foot drop prevention and accelerating the patient's recovery.
