The injection into a vein of a solution, drugs, or blood components.
The gradual introduction of fluid into the bloodstream occurs by employing a thin plastic tube called a cannula, which is inserted into a vein. This process, known as intravenous infusion, involves administering substances over a span of several hours or days and is often referred to as a “drip.” This technique is employed for various purposes, such as delivering blood (also known as blood transfusion), essential fluids, or vital salts. Intravenous infusion is also utilized to supply nutrients to individuals who cannot consume food normally and to administer specific medications. To regulate the precise quantity of the infused substance or medication, a device known as an infusion pump might be employed.
