Abstract
A control system for an intravenous feed tube is provided that functions by sensing weight changes with respect to time, i.e., dw/dt, of an intravenous solution supplied to a patient, the solution being maintained as a free hanging load. The weight changes are detected by strain gauge sensors, and then applied as signals to a microprocessor that is programmed to produce suitable control responses. These responses are fed to a motor which applies a constrictive force to the intravenous tube and maintains the solution flow at the desired rate.
