Description
Technical Field
The utility model relates to the technical field of medical equipment, especially a low limbs joint function trainer.
Background
Joint operations such as hip and knee are common treatment means for treating joint diseases of lower limbs, and the operation modes comprise joint replacement, arthroscopy, internal fracture fixation and the like. However, no matter what kind of operation mode, poor joint flexion and extension activity, decreased limb muscle strength, weakened limb body sensation, limb swelling and the like are all common complications in early stage after joint operation, if the symptoms cannot be improved in time, serious consequences such as joint stiffness, limb muscle atrophy, decreased balance ability, deep vein thrombosis and the like can occur, and the overall treatment effect is directly influenced.
Early postoperative rehabilitation of joint function helps to reduce the risk of the postoperative complications mentioned above. For the rehabilitation of joint movement function, the CPM machine is mainly used for the passive flexion and extension function training of joints, but more and more research evidences show that the passive function training does not have obvious help for the postoperative limb function rehabilitation, and the active flexion and extension movement rehabilitation training is recommended to be carried out on a bed.
For the recovery of limb muscle strength, patients are mainly advised to carry out active strength training such as leg lifting training on a bed to promote the improvement of the muscle strength, but some patients have weak bodies in the early postoperative period and cannot lift legs by themselves; for recovery of limb sensation, the patient is mainly advised to walk upright to look for limb sensation, but not get preliminary sensory training before going down the ground may increase the risk of falling; in addition, the prevention of limb swelling and deep vein thrombosis is achieved by the way that the patient needs to lift the limbs and actively perform functional training such as ankle pump and joint flexion and extension; however, when a patient performs active function training, an effective protection tool is often lacked, so that the patient exceeds the joint movement range in the training process, sprain, joint dislocation and the like are easily caused, and a training tool capable of realizing combined application is also lacked, so that the muscle strength is improved while the patient actively trains joint flexion and extension activities, and the body feels and obtains preliminary training.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the inventor has designed a training device to achieve the purpose of achieving preliminary training of the feeling of the limb body by simulating the feeling of touch before the patient goes to the ground, limiting the limb to prevent the movement beyond the range of joints during training, raising the affected limb at rest and preventing the limb from outward rotation.
Furthermore, the inventor also considers the aspects of the stability of the training device, the adjustability of the lifting angle of the lower limbs, the function of flexion and extension activities, the stability of the limbs and the like, and provides a more optimized training device.
According to an aspect of the utility model, a lower limbs joint function trainer is provided, include: training platform and ankle support, the training platform includes: the fixing plate and a chute which is arranged in the middle of the fixing plate and has an inclined trend; the ankle support includes: the first pulley is arranged at one end of the ankle support close to the sole, and the second pulley is arranged at the opposite end; the first pulley is fixedly arranged on the sliding groove, and the second pulley is detachably arranged on the sliding groove. Through locating the design on the spout with first pulley and second pulley for pulley and spout have formed one-way damping structure, and the resistance is less when the ankle support removes to second pulley direction, and the resistance is great when removing to first pulley direction, just so can make the knee joint straighten occasionally resistance effect. Therefore, the limb can be subjected to flexion and extension training on the bed, the movement range of the ankle support and the fixed sliding groove is limited, and the lower limb can be protected.
