Ostomy bag system

Each ostomy bag system has a "skin barrier" or "wafer" to protect the skin and a "bag" or "pouch" to collect bowel movements. An ostomy system can be 1-piece, where the skin barrier and the bag are a single unit, or 2-piece, where the skin barrier and the bag join together. They can close with a separate clip or have a closure system as a part of the bag.
