Infusion Pumps: A Technical and Clinical Overview

An infusion pump is a regulated medical device designed to deliver fluids, including nutrients and medications, into a patient’s body in controlled amounts. Unlike manual fluid administration, such as a gravity-fed drip, an infusion pump provides precise flow rates and automated delivery intervals, which are essential for maintaining stable therapeutic levels in the bloodstream. This article provides a neutral, technical analysis of infusion pump technology. It examines the fundamental types of pumps used in healthcare, the mechanical and electronic mechanisms that ensure accuracy, the safety protocols governing their operation, and the future of "smart" infusion systems.
