摘要:
A patient support apparatus comprises a lower frame, a lift mechanism, a drive mechanism, and an upper frame. The lower frame includes a lift drive configured to at least one of expand and contract the lift mechanism. The lift mechanism is pivotably coupled with the lower frame to rotate about a rotational axis. A drive mechanism is coupled between the lift mechanism and the lower frame. The drive mechanism is configured to rotate the lift mechanism about the rotational axis. The upper frame is supported on the lift mechanism and responsive to the rotation of the lift mechanism to rotate a patient about the rotational axis.
