Description

An IV cannula, also known as an intravenous cannula or catheter, is a medical device used to administer fluids, medications, or blood products directly into a patient's bloodstream. It consists of a hollow, flexible tube made of materials such as plastic or silicone, with a sharp needle or trocar at one end for insertion into a vein. Once inserted into the vein, the needle or trocar is removed, leaving the cannula in place. IV cannulas are available in various sizes and configurations, including different lengths, gauges (diameter), and types of wings or ports for securing the device and connecting to IV tubing. They are commonly used in hospitals, clinics, and other healthcare settings for intravenous therapy, fluid resuscitation, blood transfusions, and administration of medications or anesthesia. IV cannulas require sterile insertion techniques to minimize the risk of infection and are typically replaced periodically to maintain vein health and prevent complications such as infiltration or phlebitis.
