A sterile barrier is a protective covering designed to maintain the sterility of medical devices or products. It prevents contamination from microorganisms, ensuring that items remain free from bacteria and other pathogens until they are used. Common examples of sterile barriers include sealed packaging, sterilization pouches, and wraps. These barriers are crucial in healthcare settings, particularly in surgeries and procedures where infection control is vital. By using sterile barriers, healthcare professionals can minimize the risk of infections and ensure patient safety. Proper handling and storage of these barriers are essential to maintain their effectiveness.
