The SUR-FIT Natura Flange System signals a secure, accurate closure with a series of audible “clicks”. A simple snap-off, snap on design allows users to change the pouch quickly to match activities without removing the skin barrier from the skin. Durahesive skin barriers are designed for people whose stoma output is mostly liquid. Unlike other skin barriers that can break down around liquid output, Durahesive skin barriers swell up to protect the stoma. This special effect, called turtlenecking, helps create a more secure seal without harming the skin. ConvaTec Moldable Technology™ skin barriers provided a personalized, custom fit around the stoma to help protect the peristomal skin. They require no cutting or guess work making them very easy to use.
