Abstract

The present invention discloses a trajectory variable low limb rehabilitation training device. A seat lifting mechanism is attached to a bearing frame and adjustment of seat lifting and lowering is realized by changing relative positions of a small hole in the seat and a small hole fixed in the bearing frame; a trajectory adjusting rod is fixed on two limiting slide blocks and relative positions of rotation of a rotary disk and the two limiting slide blocks on the rod are used to realize change of trajectory of a rod rear end; an ankle fixing mechanism connected with the rod rear end is used to fix relative positions of soles and ankles of a patient, so that damages caused by relative rotary stretching of the ankle parts of the patient are prevented in a rehabilitation training process; and a parallelogram mechanism is used to connect an operating panel on the bearing frame through two corresponding rods, so that the operating panel and the bearing frame are in a fixed angle all the time and the patients are more convenient to use the operating panel. The relative positions of the sliding blocks on the rod can be automatically adjusted according to rehabilitation state of the patients, thereby changing motion trajectory of a kickstand connected with the rod rear end.

Description

technical field [0001] The invention belongs to the field of rehabilitation equipment, in particular to rehabilitation training for patients' lower limbs. Background technique [0002] (1) According to relevant surveys, there are 1.2-1.5 million new stroke cases in my country every year, and about 75% of the survivors are disabled and lose the ability to walk. In addition, diseases that cause lower limb paralysis include spinal cord injury and trauma, such as lower limb joint disease, spinal muscular atrophy, multiple sclerosis, etc. Impaired lower extremity mobility can lead to serious complications. Long-term bed rest of the patient will lead to obstruction of venous blood return of the lower limbs, poor blood supply of the lower limb tissues, etc., which will cause the decline of the physiological function of the lower limbs, and severe cases will lead to disuse syndrome. [0003] (2) Traditional studies have shown that rehabilitation training can accelerate the blood f...
