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 and 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. The perfusion system also includes an electrical power network having an electrical power line, means for selectively connecting the perfusion devices to the electrical power network, and a controller with an input device for accepting control commands from an operator. The perfusion system could also include a control device, such as a pump, a plurality of sensing devices, and means for specifying the sensing device that the control device should be accept feedback from.
