Infusion pumps are medical devices that deliver fluids like nutrients and medications into a patient's body at controlled rates. There are several types of infusion pumps including syringe pumps, multi-channel pumps, volumetric pumps, ambulatory pumps, and gravity-controlled pumps. Infusion pumps are widely used in clinical settings to accurately administer multiple fluids and drugs at different rates. They provide benefits over traditional fluid delivery methods by allowing for precise control over dosage and timing.
