摘要
.The article presents a system for monitoring fluid during intravenous infusion. The system is based on a capacitive method in which the change in electrical capacitance of the infusion container is converted into the current volume of the fluid. The capacitor pads of the measurement system are integrated into the housing of the container, facilitating easy installation in hospital conditions without significantly altering the dimensions of the infusion set. The system has been tested with target infusion fluids, and the volume measurement error within the entire measurement range is less than 6%. The current fluid volume is displayed on an LED strip to quickly inform the personnel, and the system also has the capability to provide an alarm for low fluid levels.
