AI Technical Summary

Benefits of technology

This patented technology allows for better mobility by utilizing both air (pneumatically) muscle(s), heavy duty motor(mainsaving more energy than traditional methods like hydraulic or electric). It also includes featuring an arm that can be bent at different angles without losing its strength due to gravity forces during exercise movements. Overall this makes it easier to train patients who have suffered from neurologically impaired upper limbs.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving physical exercise performance during older individuals due to their decreased muscle strength caused by necrotic neuritis or other degenerative diseases such as arthritis. Current methods involve manually guided stretchers or robotic devices used alone or combined together, making it challenges to provide accurate feedback about how well these treatments work over longer periods.

Abstract

The invention discloses a portable 2-DOF wrist joint rehabilitation robot comprising an arm rack to wear outside a human forearm, a hand back rack, to wear on the human back, and a 2-DOF drive mechanism connected between the arm rack and the hand back rack. The 2-DOF drive mechanism comprises a sliding mechanism, a pneumatic muscular mechanism, a rotary joint, a driving link, and a driven link; the rotary joint is driven by driving force of pneumatic muscles so that the driving link and the driven link drive the hand back rack for extension rehabilitation training of the wrist joint. The 2-DOF drive mechanism further comprises a central column, an arc rack, a cylindrical gear, and a guide rail fixed to the outside of the hand back rack. A motor drives a round gear to rotate so that the hand back rack drives the wrist to swing. The portable 2-DOF wrist joint rehabilitation robot has the advantages that the robot is portable and domesticized and gain amplification is achieved for controlling the angle of the rotary joint.
