Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training for patients with cerebral hemorrhage, in particular to a limb training auxiliary device for rehabilitation of patients with cerebral hemorrhage. Background Art

[0002] Cerebral hemorrhage refers to bleeding caused by non-traumatic rupture of blood vessels within the brain parenchyma, accounting for 20% to 30% of all strokes and with an acute mortality rate of 30% to 40%. Early-stage treatment requires appropriate training equipment. Patients with cerebral hemorrhage require limb training assistive devices during rehabilitation.

[0003] Limb training auxiliary devices for the rehabilitation of patients with cerebral hemorrhage usually require activity training of the patients' legs. The training auxiliary devices in the existing technology are not convenient for adjusting the angle between the thigh and the calf according to the needs of the patients, resulting in a smaller scope of application of the training and poor training effect. Therefore, we have launched a limb training auxiliary device for the rehabilitation of patients with cerebral hemorrhage. Utility Model Content
