Lower limb rehabilitation training device and system

Abstract

The invention relates to a lower limb rehabilitation training device and system. The lower limb rehabilitation training device at least comprises a supporting rack (1) used for supporting and installing a training executing mechanism, wherein the training executing mechanism at least comprises a weight reduction system (2) and a limiting assembly (3); the weight reduction system (2) can be installed on a base (13) of the supporting rack (1) in the mode of providing acting force for offsetting at least part of the gravity of a patient for the patient; under the condition that the supporting rack (1) limits the activity space of the patient, the weight reduction system (2) can adjust the working position and the applied acting force of the patient according to anthropometric parameters of the patient, so that the patient can conduct movement simulating the gait track of the human body on the supporting rack (1) in the mode that the set plantar pressure exists; the limiting assembly (3) is arranged on a weight reduction mechanism support (21) of the weight reduction system (2), and the limiting assembly (3) adjustably limits the working position of the weight reduction system (2) when the weight reduction system (2) is in linkage with rehabilitation training activities of the patient.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a lower limb rehabilitation training device and system. Background technique [0002] Since 2000, the proportion of the elderly population in my country has continued to rise. The decline in human body function brought about by the aging population and some diseases have led to an increase in the number of people who need lower limb rehabilitation. At present, the number of traditional rehabilitation therapists is very limited, and the rehabilitation effect depends on the level of the therapist. The influence of the training environment, single training mode, and high cost have made the robot-assisted training of lower limb rehabilitation gradually become the first choice. Research on medical rehabilitation robots has been started very early in foreign countries. In recent years, my country has also achieved great development in this area. [0003] Chines...

Problems solved by technology

However, this patent cannot effectively simulate the gait movement trajectory of the human body for patient rehabilitation training, and its weight-reducing traction mechanism cannot limit the movable range of its load-bearing end according to actual needs, and cannot guarantee sufficient safety for the patient. The structure is separated, which is inconvenient for patients to use and store. It takes up a lot of space, and the manufacturing cost is high, and it is impossible to achieve continuous gait track rehabilitation training activities for patients in a small space.

[0004] Although the existing rehabilitation training device can improve the effect of lower limb rehabilitation training to a certain extent, the existing rehabilitation device has a complex structure, a large space occupation rate, and a large number of degrees of freedom in the lower limb auxiliary training mechanism, which is difficult to control and operate. Some products have high manufacturing costs, many training auxiliary driving force supply unit modules, high maintenance costs and difficulties, which are not conducive to long-term cycle use, training cannot effectively imitate gait trajectory, and training effects cannot be guaranteed
