Two-Piece Systems
In a two-piece system, the ostomy pouch and skin barrier are separate.
Parts of a two-piece system
  1. Pouch — Bag that collects stool or urine
  2. Skin barrier — Adhesive part that fits around the stoma to protect the skin. (Some skin barriers include a tape border to help hold the barrier in place.)
  3. Flange — plastic ring on both the pouch and skin barrier that provides a secure attachment. To work, both flanges must be the same size and be from the same product family.
Two-Piece Systems
Advantages of a two-piece system
  1. The pouch can be removed without removing the skin barrier.
  2. Because it is separate from the pouch, the skin barrier can be more easily positioned around the stoma.
