A multi-part muscle strength training device for lower limbs

Abstract

A lower limb multi-position muscle force trainer comprises a base, a vertical support and a platform support. The vertical support is connected with the base and further connected with the platform support, a hydraulic jack is arranged on the base, and a gravity discus and a first fixed pulley are arranged on the vertical support. A second fixed pulley, a third fixed pulley and fixed blocks arranged symmetrically pairwise are arranged on the platform support, the two fixed blocks located on the same side are connected through a sliding rod, sliding blocks connected through a second connecting rod are symmetrically arranged on the sliding rods, a foot support is arranged on the second connecting rod, and the gravity discus is sequentially wound around the first fixed pulley and the second fixed pulley through a traction rope. The lower limb multi-position muscle force trainer is ingenious in design, the whole mechanism is reasonable in matching, three different training effects are achieved by simply replacing the hooking position of the traction rope, lower limb bending and stretching bidirectional muscle force training and ankle dorsiflexion training can be achieved through one instrument, and the adjusting and conversion process is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of human body auxiliary medical devices, in particular to a multi-part muscle strength training device for lower limbs. Background technique [0002] Medical theory and practice have proved that patients with sequelae of cerebrovascular infarction and cerebral hemorrhage or patients with limb injuries caused by accidents need limb training to restore limb function and prevent muscle "disuse" atrophy and joint stiffness. In order to overcome the shortage of professional medical personnel and improve the effect of rehabilitation training, various rehabilitation training devices have emerged. Generally, active rehabilitation training devices are attached to the limbs of the trainee, and the limbs are driven by the expected movement trajectory to achieve the effect of rehabilitation training. . [0003] At present, in clinical rehabilitation training, the muscle strength training of hip flexion, knee extension and knee e...

Problems solved by technology

Among them, during the PT rehabilitation treatment, the rehabilitation therapist can only treat a single patient, and the medical human resources cannot be fully utilized; the disadvantage of the quadriceps training device is that the training mode is single, and the affected limb is in a suspended state during the training, lacking the corresponding joints pressure stimulation

[0004] The invention patent with the patent number 201210173493.X and the patent name "Adduction and Abduction Training Machine for Lower Limbs" stated that the adduction and abduction movement control of the lower limbs is realized through rope traction, and the use requires the patient to be in a standing state. High, not suitable for patients who are recovering from a serious illness, and the training effect on the knee joint is not good; The frame body fixes the lower limbs and prevents adduction and internal rotation of the lower limbs when lying on the side. Training must be performed in the side lying position. Although the problem of fixing the affected limb is solved, the training effect and patient experience achieved in actual use are not good.
