Choosing between flat and convex barrier types is important because it affects how well the wafer fits against your body and supports your stoma. Convex barriers are best for flush, retracted, or irregularly shaped stomas as they gently press the skin and help protrude the stoma for a more secure seal, reducing the risk of leakage. Flat barriers are suitable for stomas that protrude naturally and for flatter abdominal surfaces. In this category, both flat and convex options are available. For example, Convatec 421458 offers a flat barrier, while Convatec 421639 features a convex design. This variety ensures you can select the barrier type that best matches your anatomy and stoma needs.
