AI Technical Summary

Technical Problem

Existing lower limb exoskeletons or walking aids are heavy, lack flexibility, and cannot provide effective counterbalancing torque when the user loses balance, increasing the risk of falls.

Method used

A portable walking assistance nursing device for elderly patients is designed, which adopts a hollow structure support component and a counterweight. The device monitors changes in body posture through a posture sensor and uses the counterweight to slide within the cavity to adjust the center of gravity, providing active balance intervention.

Benefits of technology

When a user is about to fall, the device provides positive physical intervention through dynamic center of gravity adjustment, improving safety and wearing comfort, reducing user energy consumption, and maintaining device portability.

Abstract

The invention belongs to the technical field of rehabilitation auxiliary instruments, and provides a portable walking assisting nursing device for elderly patients, which comprises a main body supporting structure, and the main body supporting structure sequentially comprises a waist fixing assembly, a thigh supporting assembly, a knee joint assembly, a shank supporting assembly and a foot assembly from top to bottom along the lower limbs of a human body; the thigh supporting assembly and the shank supporting assembly are both designed to be of a cavity structure. The sensing part is arranged on the main body supporting structure and comprises at least one attitude sensor group and a controller; the counterweight part is arranged on the main body supporting structure; wherein the counterweight part slides in the cavity structures of the thigh supporting assembly and the shank supporting assembly; the balance weight part is electrically connected with the other end of the controller of the sensing part, and when the posture sensor group detects a signal indicating that the human body is about to fall due to abnormal inclination, the controller immediately sends an instruction to the balance weight part to drive the balance weight part to quickly move in the direction opposite to the falling direction of the human body.
