Joint suspension decompression exerciser and control method thereof

Abstract

The invention belongs to the field of medical auxiliary devices, and discloses a joint suspension decompression exerciser and a control method thereof. Left and right upper moving arms at the upper end of a joint motion supporting frame are separately inserted into two pairs of suspension sliding slots on both sides of a suspension supporting frame, and the suspension supporting frame is suspendedupwards along the long axis of the upper moving arm through the repulsion force of the magnetic suspension or the elastic repulsion force of a spring device; the suspension supporting frame upwards drives the thigh and the shank of lower limbs of a human body to be separated, so that the gap of the knee joint is increased, and the knee joint is continuously decompressed; if the action fulcrum ofthe suspension supporting frame is changed to support the ischial tuberosity, the pressure on the hip joint can be relieved. The invention can carry out full decompression on the affected knee or hipjoint and maintain the motion function of the knee or hip joint not to be influenced at the same time for patients with osteoarthritis, and provides a brand-new solution for alleviating the wear of the knee joint or the hip joint of a patient, relieving the pain of the affected limb, promoting the recovery of the motion capability of the affected knee joint, realizing virtuous cycle and finally promoting the cartilage regeneration and the perfect reconstruction of motor function.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, in particular to a joint suspension decompression exerciser and a control method. Background technique [0002] Currently, in osteoarthritis, the joint space is narrowed, and the cartilage is worn away, leading to adhesions, deformity and stiffness of the joints. Because the narrow joint space will aggravate the wear of the knee and hip joint surfaces, joint movement disorders will appear, and the movement disorders will lead to related muscle atrophy and atrophy, and vice versa. The two form a vicious circle, and a considerable number of patients become disabled. Joint decompression not only avoids joint wear and tear, but also provides space for the regeneration and repair of articular cartilage, which is conducive to the regeneration and rehabilitation of joint motion function. [0003] However, at present, most of the decompression devices for knee joints and hip joints are fixed d...

AI Technical Summary

Problems solved by technology

[0003] However, at present, most of the decompression devices for knee joints and hip joints are fixed decompression supports, which have extremely adverse effects on the regeneration of articular cartilage and the recovery of motor function.

[0004] Through the above analysis, the existing problems and defects of the prior art are: most of the decompression appliances for knee joints and hip joints are fixed decompression braces, which not only limit the recovery of joint motion function, but also imprison the articular cartilage regeneration. Compressive stress and shear stress stimulation have extremely adverse effects on articular cartilage regeneration and recovery of motor function

[0005] The difficulty in solving the above problems and defects is: the existing joint decompression methods such as knee joints and hip joints are mostly hinged fixed decompression, which makes the joints stiff, which not only limits the joint movement, but also confines the stress stimulation of articular cartilage regeneration. That is to say, the difficulty in solving the above problems and defects lies in maintaining the normal activities of the joint while decompressing the joint.
