Drive system for bed

摘要

A bariatric patient management system includes a single-wheel drive system having bi-directional variable speed control through use of a variable control joystick. The single-wheel drive system is disposed on an underside of the bariatric patient management system and engages a floor surface when the bariatric bed is in a lowermost position. The bariatric patient management system further includes a removable headboard having a disconnect feature for disconnecting the variable control joystick from the single-wheel drive system when the headboard is removed. A plurality of three-setting casters is used in conjunction with the single-wheel drive to allow the bariatric patient management system to be manually turned when transported from one location to another. The bariatric patient management system further includes an improved trapeze boom that allows for additional access to a patient adjacent the headboard of the bariatric patient management system.
