NCI: A device designed to control or regulate the operation of another device.,UMD: Devices designed to regulate the operation of a device, equipment, or system. These devices may consist of a variety of mechanical, electrical, electromechanical, or electronic components or component sets according to the intended function; they may also consist of modules that, when used with a parent device (e.g., a specialty bed/mattress system), provide additional ability to control such functions. Controllers frequently are used in healthcare facilities to control environmental conditions, equipment operation variables (i.e., temperature and fluid pressure or level), and/or the functioning of more complex devices such as electrosurgical units and radiographic systems. Controllers can be an integral part of equipment and systems or available as stand-alone devices that are used in conjunction with the devices/systems.
