Description

Technical Field

[0001] This invention relates to the field of rehabilitation training devices, and in particular to an intelligent rehabilitation training device. Background Technology

[0002] When caring for patients in the neurology department, in order to activate the damaged neural pathways and improve the muscle contraction ability, rehabilitation training devices are usually used to carry out rehabilitation training for the patient's limbs. In the actual application of the training device, in order to avoid cross-infection caused by sweat and dirt residue, the foot pedal part usually needs to be cleaned and disinfected in time after the training is completed.

[0003] However, when cleaning and disinfecting rehabilitation training devices, medical staff usually need to manually disinfect and wipe the foot pedals. This is not only time-consuming and affects the efficiency of cleaning and disinfecting the training device, but also requires medical staff to use restraint straps to restrain the patient's feet and the pedals to improve the training effect and prevent the patient's feet from slipping off the pedals due to insufficient limb strength. This not only increases the workload of medical staff, but also affects the convenience and flexibility of using the rehabilitation training device in actual application. Summary of the Invention

During the process of the foot leaving the foot pedal after training, the positioning support plate automatically resets, improving the ease of operation when binding and positioning the patient's foot and the foot pedal. Simultaneously, the force exerted during the automatic reset of the positioning support plate automatically drives the protective auxiliary mechanism, enabling automatic replacement of the non-woven fabric. This ensures the safety of the device in practical applications, avoids the risk of cross-infection, improves the efficiency of cleaning and disinfection, ensures aseptic use of the device, and reduces the workload of medical staff.
