Abstract: A controller provides an abstract, “virtual” interface between the software based applications resident in the controller and the hardware elements of the fluid processing system. The controller also provides a straightforward yet very interactive dual region user interface.

Abstract: A medical fluid processing device for processing blood or other fluids includes a plurality of hardware elements that perform specific functions. Different processing procedures are achieved by performing the specific functions in appropriately arranged sequences and combinations. A user accessible menu permits user selection of the desired processing procedure. A dual region, user accessible screen provides user interaction with the processing device.

Abstract: A medical fluid processing device for processing blood or other fluids includes a plurality of hardware elements that perform specific functions. Different processing procedures are achieved by performing the specific functions in appropriately arranged sequences and combinations. A user accessible menu permits user selection of the desired processing procedure. A software implemented "virtual" interface generates appropriate hardware commands for actuating the hardware elements as needed to achieve the desired processing procedure. A dual region, user-accessible screen provides user interaction with the processing device. The "virtual" interface provides positive control over the individual hardware elements in combination with sufficient system flexibility to achieve useful interactivity with the processing device operator.
