A cannula is a thin, flexible tube that is inserted into the body to deliver or remove fluids. It is commonly used in medical settings for various purposes, such as administering medications, fluids, or oxygen. Cannulas can be found in different sizes and types, depending on their specific use. Cannulas are often used in procedures like intravenous therapy or surgery. They can also be used in respiratory therapy to help patients breathe more easily. The design of a cannula allows for minimal discomfort while providing essential access to the body’s systems.
