Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training, in particular to a rehabilitation training device for patients with lower limb fractures. Background Art

[0002] Lower limb fractures refer to the breakage of bones in the lower limbs due to severe external forces. This injury can be caused by various reasons, such as traffic accidents, sports injuries or high-fall accidents. Lower limb fractures not only cause severe pain and dysfunction, but also cause great distress to patients' daily lives. Rehabilitation training for patients with lower limb fractures is the key to restoring and reconstructing the corresponding functions of the fracture site. In the initial stage of the fracture, surgical treatment is generally performed. It is crucial to start rehabilitation training as soon as possible after the operation, because early activity helps reduce the risk of muscle atrophy, joint stiffness and thrombosis.

[0003] At present, the common rehabilitation training devices for patients with lower limb fractures on the market are not convenient to adjust the angle of the device according to the patient's posture when using it (such as sitting or lying down, etc.), which makes it inconvenient for some patients who have difficulty sitting or standing to use it. The applicability of the device is weak and the applicable population is small. In addition, the common rehabilitation training devices are not convenient to adjust the distance between the patient's feet and the pedals according to the patient's leg length. The entire device is often required to be moved, which is more manpower-consuming, and some places are not suitable for placing the entire device, resulting in few applicable scenarios for the device.

[0004] To this end, we proposed a rehabilitation training device for patients with lower limb fractures to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a rehabilitation training device for patients with lower limb fractures, so as to solve the problem that it is inconvenient to adjust the angle of the device according to the posture of the patient when using it, and that ordinary rehabilitation training devices are inconvenient to adjust the distance between the patient's feet and the pedal according to the patient's leg length.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rehabilitation training device for patients with lower limb fractures, comprising a base plate, a support plate hingedly arranged on the top of one side of the base plate, and a fixing plate fixed in the middle of the top of the supporting plate, a control cabin slidingly sleeved on the outer surface of the fixing plate, and a PLC control panel arranged on one side of the control cabin, connecting rods rotatably inserted on both sides of the top of the control cabin, and a pedal body rotatably arranged on one end of the connecting rod through a bearing.

[0007] Preferably, a screw rod is rotatably inserted into one side of the interior of the base plate, and one end of the screw rod passes through one side of the base plate and is fixed with a handle, a sliding rod is fixed to the other side of the interior of the base plate, and a moving block is slidably sleeved on the outer surface of the sliding rod, support rods are hinged on both sides of the moving block, and one end of the support rod is hingedly connected to the bottom surface of the support plate.

[0008] Preferably, both sides of the fixing plate are provided with card slots, and there are multiple groups of card slots, and the multiple groups of card slots are symmetrically and equidistantly distributed on both sides of the fixing plate in a linear array.

[0009] Preferably, the moving blocks are provided in two groups, wherein the moving blocks in one group are slidingly sleeved on the outer surface of the slide rod, and the moving blocks in the other group are threadedly slidingly sleeved on the outer surface of the screw rod.

[0010] Preferably, the outer walls on both sides of the bottom end of the control cabin are fixed with limit frames, and a screw is inserted through the middle thread of the limit frame, and return springs are fixed to both ends of the inner wall of the limit frame, and a clamping block is fixed to one end of the return spring.

[0011] Preferably, the card block is slidably inserted at both sides of the bottom end of the control cabin, the size of the card block is adapted to the size of the card slot, one end of the card block passes through one side of the control cabin and is slidably inserted inside the card slot, and the other end of the card block is tightly attached to one end of the screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the utility model;

[0013] By installing the base plate, support plate, screw rod, handle, slide rod, movable block and support rod and using them together, the angle of the support plate can be adjusted according to the patient's usage posture, so that a comfortable and reasonable angle can be maintained between the foot pedal body and the patient's foot, thereby improving the patient's training effect, reducing the patient's discomfort, and enhancing the patient's usage experience. Different angle adjustments can enable patients who have difficulty sitting to use the device normally, thereby increasing the applicable population of the device and providing greater convenience for patients.

[0014] By installing a fixing plate, a control cabin, a limit frame, a screw, a return spring, a card block and the provided card slot, the distance between the foot pedal body and the patient's foot can be adjusted according to the leg length of different patients, so that the device can be in reasonable contact with the patient.
