Coloplast SenSura® Mio 1-Piece EasiClose® Wide Outlet Soft Convex Maxi Pouch – Black with Window, Cut-to-Fit, 3/8"–2" (10–50 mm), #18991

Coloplast SenSura Mio Soft Convex 1-Piece Drainable Pouch #18991 is designed to provide a secure, flexible fit for people with a stoma that needs gentle support or who have uneven peristomal skin contours. The integrated soft-convex baseplate combines adaptive convexity with elastic adhesive technology to help the barrier conform to movement, creases, folds, and changing body shape.

This Maxi-size, black opaque pouch features a discreet inspection window, allowing the stoma and output to be checked during application without sacrificing the low-profile appearance of an opaque pouch. The cut-to-fit skin barrier can be trimmed for stomas measuring 3/8" to 2" (10–50 mm).

An EasiClose Wide Outlet supports simple, controlled emptying, while the full-circle filter is designed to help reduce ballooning. The soft, water-resistant textile backing is intended to improve comfort and minimize friction against clothing and skin. Because this is a one-piece system, the pouch and soft-convex barrier are removed and replaced together during a pouch change.

Product Specifications

Soft convexity is generally intended for stomas that sit above skin level but need added support because of nearby folds, creases, or uneven skin contours. A clinician or WOC nurse can help determine whether Soft, Light, or Deep convexity is appropriate for an individual stoma and body profile.
