infusion pump is a medical device used to deliver fluids, like nutrients or medications, into a patient’s body in controlled amounts, providing precise delivery rates and volumes, often used for administering medications like antibiotics, chemotherapy drugs, pain relievers, hormones, and insulin, particularly when a patient needs a continuous intravenous (IV) infusion; key features include the ability to program specific flow rates, alarms to alert of potential issues like occlusion or low battery, and advanced “smart pump” technology to minimize medication errors by checking against drug libraries and programmed safety limits.
