ConvaTec SUR-FIT Natura - Durahesive Convex Moldable Skin Barrier has the ability to swell up and "turtleneck", protecting the stoma when liquid output is present. This creates a more secure seal but without harming the skin. This secure seal instills confidence in the user and makes this skin barrier ideal for those whose stoma output is mostly liquid. The coupling ring allows the pouch and barrier to snap together for a solid fit. Available in flat or convex style, these skin barrier wafers fit a variety of stoma sizes and shapes.
