SenSura Click is a two-piece mechanical coupling system that combines the unique double-layer adhesive with an audible ‘click' to ensure secure locking of the pouch to the barrier. SenSura Click barriers are available in convex light. The oval shape of the convex light barrier is designed to help a stoma that is difficult to manage -- for example, a stoma that is flush, retracted, or located in a skin fold. It applies light and directed pressure on the peristomal skin to reduce the risk of leakage by allowing the stoma to protrude.
