sterile barrier system
Also written as: SBS — Sterile Barrier System
The packaging configuration that provides and maintains sterility of medical devices until they are used, including the sterile barrier and any protective packaging.
Full Definition
A sterile barrier system encompasses all packaging components that work together to create and maintain a sterile environment for medical devices throughout storage, transport, and handling until point of use. This system includes the primary sterile barrier (such as sterilization wrap, pouches, or rigid containers) that directly contacts the sterile device, plus any secondary packaging that provides additional protection. The barrier system must allow sterilant penetration during processing while preventing microbial ingress afterward. Key performance characteristics include seal integrity, material compatibility with sterilization methods, aseptic presentation features, and shelf-life maintenance. The entire system must be validated for its intended sterilization method and storage conditions.
Usage
Usage note: Encompasses the complete packaging solution, not just individual barrier materials.
