An I.V. (Intravenous) Set is a medical device used to administer fluids, medications, or nutrients directly into a patient’s bloodstream through a vein. It consists of a long sterile tube, a drip chamber to control the flow of fluids, a roller clamp for flow regulation, and a needle or catheter that is inserted into the vein. I.V. sets are commonly used in hospitals and clinics for hydration, medication delivery, and blood transfusions. They are designed for single-use to prevent contamination, ensuring patient safety. These sets are available in various sizes to accommodate different medical needs and flow rates.
