User interface and control system for powered transport device of a patient support apparatus
First Claim
1. A patient support apparatus comprisinga frame,a patient support coupled to the frame,a plurality of casters coupled to the frame,a wheel coupled to the frame,a motor coupled to the wheel and operable to rotate the wheel to propel the patient support apparatus along a floor,an electrical system comprising a battery, recharging circuitry for the battery, an AC power plug that is pluggable into a power outlet to provide electrical power for recharging the battery, and a controller to control operation of the motor, the controller being configured to signal operation of the motor to rotate the wheel to propel the patient support apparatus along the floor even when the AC power plug is plugged into a power outlet.

Abstract
A patient support apparatus has a powered transport device that is operable to propel the apparatus along a floor in forward and reverse longitudinal directions, as well as in left and right lateral directions. A user input for selection of discrete speed settings for the powered transport device is included on the patient support apparatus. User inputs for controlling the direction that the apparatus is propelled are provided at the head end, foot end, and both sides of the patient support apparatus.
