SenSura Mio Convex Soft Drainable Pouch, Black, Maxi, Cut-to-Fit 5/8"–1-5/16" (Coloplast 18990), 10 per box

Gentle Convex Support for Uneven or Recessed Stomas

The SenSura Mio Convex Soft (SKU 18990) pairs Coloplast's elastic adhesive with a soft convex baseplate, giving the barrier gentle inward pressure around the stoma. This is designed for stomas that sit flush or slightly recessed, uneven peristomal skin, or areas with scarring and folds — situations where a flat barrier alone often struggles to seal.

Built for Higher-Output Stomas

This is a one-piece drainable pouch rather than a closed pouch, so instead of removing and replacing the whole unit at each change, you empty it through a tail closure as needed throughout the day. That drainable design, combined with the Maxi pouch length, gives it the capacity commonly needed for ileostomy output, which tends to be more frequent and liquid than colostomy output.

Soft, Fabric-Like Material in Discreet Black

Made from a soft woven textile rather than standard plastic film, this pouch feels closer to clothing than to a medical device against the skin. The black colorway is designed to stay concealed under both light and dark fabrics.

Full-Circle Filter Reduces Ballooning

An integrated full-circle filter vents gas continuously, reducing the ballooning that unfiltered pouches can develop — a particular concern for ileostomy output, where gas production tends to be more frequent. This also helps manage odor between changes.

 Cut-to-Fit Convex Sizing

This version ships uncut, letting you trim the convex opening to match your stoma precisely, within a 5/8" to 1-5/16" (15–33mm) range. Because convex products apply pressure to the skin around the stoma, correct sizing matters even more here than on a flat barrier — a poor fit can cause pressure injury rather than just leakage. If you haven't used a convex product before, it's worth confirming fit with a WOCN (wound, ostomy, continence nurse) before switching.

FAQ Page

Q: Is this pouch specifically made for ileostomies, or can it be used for other stoma types? A: It's not exclusively an ileostomy product, but the drainable design, convex support, and filter make it a common choice for ileostomy users, since ileostomy output tends to be more frequent, liquid, and gas-producing than colostomy output. Convex, drainable systems like this one are also used for some urostomy and colostomy situations where the stoma is flush or recessed.

Q: What does "convex" mean, and how do I know if I need it? A: A convex baseplate curves outward slightly to press gently into the skin around the stoma, which helps the stoma protrude further and seal better. It's typically recommended for stomas that are flush with or below skin level, or for skin with folds, scarring, or creases that make a flat barrier hard to seal. If you're unsure whether convex is right for you, a WOCN can assess your stoma and skin during a fitting.

Q: What's the difference between "Soft" convex and other convex options? A: SenSura Mio's convex line includes Soft, Light, and Deep options, offering increasing levels of firmness and depth. Soft convex provides the gentlest support and is typically the starting point for people new to convexity or those with more sensitive peristomal skin; Deep convex is firmer and intended for more pronounced recession.

Q: How do I size the cut-to-fit opening on a convex pouch? A: Measure your stoma at its widest point using a sizing guide, then trim the barrier opening to that measurement within the 5/8"–1-5/16" range. With convex products, err on the side of following your measurement precisely rather than sizing generously — too large an opening reduces the convex pressure's effectiveness, and too small can cause pressure injury to the stoma.

Q: How is a drainable pouch different from a closed pouch? A: A drainable pouch has an opening at the bottom that you empty through a tail closure, so one pouch can be worn for a day or more and emptied multiple times. A closed pouch has no opening and is removed and replaced as a whole unit at each change. Drainable pouches are typically preferred for higher-output stomas like ileostomies.

Q: What does the filter do on this pouch? A: The full-circle filter vents gas out of the pouch continuously to reduce ballooning, which is especially relevant for ileostomy output given its higher gas volume. It also helps manage odor between empties.

Q: How many pouches come in a box, and how often will I need to reorder? A: This item ships 10 pouches per box. Wear time varies by individual output, skin, and activity level, so how often you'll reorder depends on your personal change schedule — ask your ostomy nurse for guidance if you're newly using a convex or drainable system.

Q: Does Parthenon offer free shipping on this item? A: Yes — orders over $100 within the contiguous United States ship free, and Parthenon backs its pricing with a lowest price guarantee.
