Medical test apparatus

A medical test apparatus, comprising: a control panel (2), a master apparatus (4) and a lifting and supporting arm device (3) connected to the master apparatus (4) and the control panel (2). The lifting and supporting arm device (3) comprises: a power source (32) having an output shaft (321), for outputting a rotational force causing the output shaft (321) to rotate around a longitudinal direction axis thereof; a planar linkage mechanism (31), comprising a secondary movement member (316) and a primary movement member (313), a rotating pivot (315) of the planar linkage mechanism (31) being fixed on the master apparatus (4), and the control panel (2) being horizontally connected to the secondary movement member (316); and a transmission mechanism (33) comprising a transmission shaft (331) and a torque conversion member (332), an end of the transmission shaft (331) being connected to the output shaft (321) so as to rotate with the rotation of the output shaft (321), and a torque output portion being provided on the torque conversion member (332) for connection to the primary movement member (313). The medical test apparatus solves the problem in the prior art of an operating platform lifting structure being complicated, costly and inconvenient to maintain.
