Knee joint rehabilitation instrument for the elderly

Abstract

The invention discloses a knee joint rehabilitation instrument for the elderly, which belongs to the technical field of knee joint rehabilitation equipment. A knee joint rehabilitation instrument for the elderly, including a rehabilitation training box, the outer wall of the front side of the support frame is symmetrically connected with the expansion rod through the rotation of the pin shaft, and the lower end of the expansion rod is connected with a plurality of connecting rods through the rotation of the pin shaft. The C-pillar is connected and fixed, and the outer wall of the C-pillar is circular and equidistantly provided with multiple springs B. The outer side of the C-pillar is equipped with a protective corrugated sleeve. There is an elastic fixing belt in the middle, and the cooperation between the structures avoids the situation that it is driven by external force, but the patient does not use force and cannot perform effective exercise, which improves the effect of training and rehabilitation. At the same time, the patient can exercise according to his own situation. Controlled, there will be no strain or wound recurrence, which improves the effect of rehabilitation.

Description

technical field [0001] The invention relates to the technical field of knee joint rehabilitation equipment, and more specifically, relates to a knee joint rehabilitation instrument for the elderly. Background technique [0002] The knee joint is composed of the lower end of the femur, the upper end of the tibia, and the patella. It is the largest and most complex joint in the human body and belongs to the pulley joint. Knee osteoarthritis is the most common musculoskeletal disease and the leading cause of disability in middle-aged and elderly people. 85% of total knee replacements are due to knee osteoarthritis. And it is easy to cause symptoms such as rheumatism, such as knee joint elderly people often make some symptoms, after the knee joint of the old man falls ill, it is necessary to carry out operations and other treatments on the knee joint of the old man. The prior art publication number is CN211244390U, which provides a knee joint rehabilitation device for the elder...

AI Technical Summary

Problems solved by technology

The prior art publication number is CN211244390U, which provides a knee joint rehabilitation device for the elderly. The device prevents the elderly from using the support rod for a long time by setting a sponge pad on the top of the support rod. The second limit rod limits the rotation of the first telescopic rod and the second telescopic rod to prevent the reverse rotation of the first telescopic rod and the second telescopic rod. The two telescopic rods are bent, and when the first telescopic rod and the second telescopic rod move, they will drive the elderly's thighs and shanks to move. Although the device has more beneficial effects, the following problems still exist: the device is provided with two crutches. The support rod drives the elderly's legs to stretch through the expansion and contraction of the telescopic rod. The device is driven by external force, and the patient does not use force, so he cannot perform effective exercises. If the external force is used to pull it faster, it will cause strain or wound recurrence. , and the existing publication number is the document CN210020204U, the training bench is set, and the door needs to be turned to a fixed place, which is very inconvenient. In view of this, we propose a knee joint rehabilitation instrument for the elderly
