Abstract
A medical pump or the like provides for a multi-function flow monitor that provides for capacitive plates positioned on opposite sides of the IV line to sense changes in the electrical environment within the IV line to deduce IV line pressure, the presence of IV fluid bubbles, the presence of the IV line within the pump, and/or correct pump operation. Each of these conditions may be determined by different analysis of the capacitance across the capacitive plates.
