Patent ID: 8197438

Claim:
A medicinal fluid delivery system comprising: a controller configured to detect when a fluid delivery path is volumetrically full with a medicinal fluid; a medicinal fluid pump operably connected to the controller and fluidically connected to a tube comprising at least a portion of the fluid delivery path, wherein the fluid delivery path comprises a proximal end and a distal end; a first electrode in electrical communication with the controller; and a second electrode in electrical communication with the controller wherein, the controller is configured to measure an electro-transmissive quality of the medicinal fluid when: the pump dispenses the medicinal fluid into the fluid delivery path; the proximal end is in contact with the first electrode; and the distal end is in contact with the second electrode; wherein the controller is further configured to provide an indication that the entire fluid delivery path from the proximal end to the distal end is volumetrically full when the controller detects that the entire fluid delivery path is volumetrically full with the medicinal fluid.
