Patent Issued for Multi-sensor infusion system for detecting air or an occlusion in the infusion system (USPTO 12048831).

A patent has been issued for a multi-sensor infusion system that can detect air or an occlusion in the infusion system. The system includes a pump, multiple types of sensors, a processor, and memory. The sensors are designed to indicate the presence of air in the fluid delivery line, and the processor uses measurements from the sensors to determine if there is air, a partial occlusion, or a total occlusion in the line. The system can also determine the percentage of air present or the probability of air being in the line. The patent aims to address the limitations of existing single-sensor based systems. The patent was filed by inventors from various locations in the United States and is assigned to ICU Medical Inc. [Extracted from the article]
