AI Technical Summary

Technical Problem

The existing technology is difficult to effectively prevent falls in a home environment, especially for elderly patients and stroke patients. The existing rehabilitation technology is usually designed as an institutionalized system, covering a large area, complex operation, and not suitable for daily living environments.

Method used

A motion assist device is designed, which includes a mobile base, a pivotable seat and a balance assist unit. The mobile base consists of multiple wheels, the seat can pivot between a sitting position and a standing position, and the balance auxiliary unit provides balance and weight support through a balance auxiliary link mechanism and a body support module. The device is also equipped with a variable braking system and sensor device that can automatically track the user and adjust the stiffness to prevent falls.

Benefits of technology

The device can effectively assist the daily activities and rehabilitation training of elderly patients and stroke patients in a home environment, improve the user's balance ability and independence, and reduce the risk of falling. Its flexibility and adaptability move beyond the limitations of traditional rehabilitation equipment and provides a more personalized and efficient rehabilitation solution.

Abstract

A mobility assist device includes a mobile base that is movable along a mobile base movement plane, the mobile base having a plurality of wheels. The mobility assist device includes a seat that is pivotally connected to the mobile base so as to be pivotable between a sitting configuration and a standing configuration, in which the seat is oriented parallel to the mobile base movement plane in the sitting configuration, and in which the seat is oriented perpendicular to the mobile base movement plane in the standing configuration, and the sitting surface of the seat faces forward relative to the forward movement direction of the mobile base. The mobility assist device includes a balance assist unit having: a balance assist linkage mechanism that is connected to the seat; and a body support module that is connected to the balance assist linkage mechanism. Components of the balance assist linkage mechanism are movably engaged to allow movement of the body support module relative to the seat along a module movement plane that is parallel to the mobile base movement plane when the seat is in a vertical configuration.
