IV catheter

An intravenous (IV) catheter is a small, flexible tube inserted into a vein, typically in the arm or hand, to deliver fluids, medications, or nutrition directly into the bloodstream. It allows healthcare providers to administer treatment quickly and efficiently, especially when patients cannot take medicines orally or need rapid effects. Once inserted, the catheter stays in place with a secure dressing, and the flow can be adjusted as needed. IV catheters are common in hospitals and clinics for hydration, medication delivery, blood tests, and other medical procedures.
