Abstract

A medical apparatus for standing aid comprising a backrest (4) that has at least one side thereof provided with a crank rocker mechanism that comprises a crank mechanism (1), a triangular linkage mechanism (2), and a rocker mechanism (3), the crank mechanism (1) being rotatably connected to the triangular linkage mechanism (2) such that an included angle between a second driven link (BE) of the triangular linkage mechanism (2) and the crank mechanism (1) is always smaller than 90°, and the crank mechanism (1) driving the triangular linkage mechanism (2), the rocker mechanism (3) and the backrest (4) connected to the triangular linkage mechanism (2) to perform interactive movement repeatedly along a predetermined curve trajectory in response to a driving force coming from a drive effect of a driving unit (100), so that the backrest (4) connected to the second driven link (BE) assists a trainee in standing up repeatedly by obliquely supporting the trainee's waist.
