Description

Technical Field

[0001] The invention belongs to the field of medical rehabilitation equipment, in particular to a single-person operable auxiliary device for the recovery of cerebral infarction patients. Background Art

[0002] Cerebral infarction, newly called cerebral infarction, refers to ischemic necrosis or softening of localized brain tissue caused by impaired blood supply, ischemia and hypoxia in the brain. After the cerebral infarction patient is cured, corresponding rehabilitation exercises are needed to improve the patient's self-care ability and quality of life, which in turn helps to improve symptoms such as lower limb weakness and difficulty walking that may occur after cerebral infarction.

[0003] An invention patent for a lower limb rehabilitation training device for patients with cerebral infarction is disclosed on the China Patent Network, and its authorization announcement number is CN114042292B. Although the device can assist and support patients when exercising on a treadmill through the cooperation of a waist harness component, a dynamic reset mechanism and a buffer mechanism, the device can only allow patients to perform horizontal walking exercises on the treadmill, and cannot adjust the walking slope of the patients during exercise, nor adjust the damping force received during walking, which results in a relatively single exercise method for patients, making it difficult to perform targeted exercises for different patients, and having a small scope of application.

[0004] In view of this, a single-person-operable auxiliary device for the recovery of cerebral infarction patients with multiple exercise methods is proposed. Summary of the invention
