Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training devices, and particularly to an intelligent rehabilitation training device. Background Art

[0002] When nursing patients in the department of neurology, in order to activate the damaged nerve pathways of the patients and improve the contraction ability of the muscles, a rehabilitation training device is usually used to perform rehabilitation training on the limbs of the patients. During the actual application of the training device, in order to avoid cross-infection caused by the remaining sweat and stains, it is usually necessary to clean and disinfect the footrest part in time after the training.

[0003] However, when cleaning and disinfecting the rehabilitation training device, it is usually necessary for medical staff to manually disinfect and wipe the footrest. This not only makes the operation more laborious and affects the cleaning and disinfection efficiency of the training device, but also when the patient is training, in order to improve the training effect and prevent the patient's foot from slipping off the pedal due to insufficient limb strength, it is usually necessary for medical staff to use a restraint band to restrain the patient's foot and the pedal. This not only increases the workload of the medical staff, but also affects the use convenience and flexibility of the rehabilitation training device in the actual application process. Summary of the Invention
