AI Technical Summary

Technical Problem

Existing knee rehabilitation braces lack the ability to precisely limit the range of motion of the joint and dynamically adjust the pressure during rehabilitation training. They cannot flexibly adjust the protection intensity according to the patient's rehabilitation progress, and cannot meet the dual needs of fixation support and rehabilitation training, resulting in limited rehabilitation effects.

Method used

An adjustment assembly comprising a slide rail, a slider, and a limiting component is designed. The sliding range of the slider is controlled by adjusting the position of the limiting component. Combined with the D3O elastic buffer telescopic rod and arc frame design, it achieves precise limiting of the knee joint and flexible adjustment of the protection strength. Equipped with a foldable support frame and traction component, it supports autonomous and automatic rehabilitation training.

Benefits of technology

It enables precise control of the knee joint bending angle according to the patient's rehabilitation progress, taking into account both the needs of fixed support and step-by-step rehabilitation training, avoiding secondary injury, and improving wearing comfort and the safety and convenience of rehabilitation training.

Abstract

The present application relates to the technical field of medical rehabilitation equipment, and discloses an adjustable pressure protector for knee joint rehabilitation, which comprises upper and lower supports fixed on the thigh and the lower leg respectively, a fixing arm is fixed on the side wall of the upper support, and an opening is formed in the surface of the fixing arm; a connecting arm is fixed on the side wall of the lower support, an adjusting assembly is arranged on the connecting arm, the adjusting assembly comprises a slide rail located on the outer side of the connecting arm and fixedly connected with the fixing arm at one end, a sliding block is slidably arranged in the slide rail, one end of the connecting arm is rotatably connected with the sliding block, a moving opening is formed in the side wall of the slide rail, and a protruding layer is fixedly arranged on the side wall of the sliding block and passes through the moving opening. The adjusting limiting piece can be used to accurately control the sliding range of the sliding block, thereby limiting the bending angle of the knee joint, and the protection strength can be flexibly adjusted according to the postoperative rehabilitation progress of the patient, so that the requirements of fixed support and stepwise rehabilitation training can be met.
