Abstract

A medical perfusion system for use in connection with the medical treatment of a patient is provided with a first type of perfusion device in the form of a blood pump adapted to pump blood through a fluid conduit connected to the patient, a second type of perfusion device in the form of a sensing device adapted to sense a condition and generate a sensing signal relating to the condition, and a controller with an input device for accepting control commands from an operator. The perfusion system also includes a display device for generating visual displays relating to the perfusion system and means coupled to the display device for generating a perfusion circuit image comprising an image of each of the perfusion devices and an image of a fluid conduit.

Claims
