Abstract: A wheeled medical device—such as a cot, stretcher, bed, wheeled chair, or other medical device—includes a pole on which is mounted a removable topper. The topper may include a plurality of IV hooks used to support an IV bag. The hooks may be defined in an endless ribbon that is circular, or that is another closed shape. No prongs, hooks, or other projections extend outwardly from the topper, thereby reducing the potential dangerousness of accidental impacts with the topper. Whether the topper includes hooks or not, it may also be used as an information communication medium, such as through the use of colors, shapes, or other structures that signify certain information. The information may identify characteristics of the patient associated with the medical device or characteristics of the medical device itself, or still other information.
