Description Assura AC Convex Light Standard Wear Barriers with Belt Tabs have a shallow convexity for flush or slightly retracted stomas providing flexibility, security, and low pressure to the abdomen. Cut-to-fit skin barrier, called a "base plate" in the AC (Adhesive Coupling) system, must be used with an Assura AC color code matched pouch. The base plate adheres to the skin; the pouch adheres to the base plate, no rigid coupling to snap together. Assura AC features a flexible, adhesive two-piece coupling system that conforms to the body. Low profile with shallow convexity. Belt loops integrated as part of the barrier.
