Abstract

A modular drive device for driving a first driven module of a first emergency patient motion device or a second driven module of a second emergency patient motion device, the first driven module being different from the second driven module. The modular drive device comprises a motor, and an output device operatively coupled to and drivable by the motor. The output device transmits mechanical force from the motor to the first driven module when said output device is coupled to the first emergency patient motion device and from the motor to the second driven module when said output device is coupled to the second emergency patient motion device. The modular drive device further comprises a controller operable in a first motor mode and a second motor mode. The first motor mode corresponding to the first driven module, and the second motor mode corresponding to the second driven module.
