An infusion pump is a medical device used to deliver fluids, medications, or nutrients directly into a patient's bloodstream in a controlled manner. These pumps can be programmed to administer precise amounts of substances over specific time intervals, ensuring accurate dosing and minimizing the risk of human error. Infusion pumps are commonly used in hospitals and clinics for patients requiring continuous medication, such as those receiving chemotherapy or pain management. They can also be used for delivering insulin in diabetic patients or for providing hydration and nutrition in patients unable to eat normally.
