Key Features

• Maxi pouch — 8.5" (570ml) capacity for higher output between changes
• Integrated three-layer filter — neutralizes odor and releases gas to prevent pouch ballooning
• Rotatable mechanical coupling — pouch can be rotated to desired position (standing, lying, emptying) before locking
• Audible click coupling — confirms secure attachment to barrier; no visual check required
• Coupling repositionable for left- or right-handed use
• Independent pouch removal — change pouch without removing or disturbing the skin barrier
• Spiral adhesive on barrier — secure adhesion with moisture absorption for skin protection
• Soft, water-repellent backing — quick-dry after showering or swimming
• Transparent film — visual stoma and output monitoring without removal
• Anatomically shaped for discrete, comfortable wear
• Compatible with color-coded Assura barriers only — not compatible with SenSura Mio Click
• Made in USA | FSA eligible | Latex free

Clinical FAQs

What does "maxi" mean and when is a maxi-capacity pouch clinically indicated?

Maxi refers to the pouch volume — this Assura closed pouch holds 570ml (8.5"). Standard closed pouches typically hold 300–400ml. A maxi pouch is indicated for patients with higher stoma output who want fewer pouch changes per day, patients with unpredictable output timing who need greater volume reserve, or those who prefer the security of knowing the pouch has additional capacity before changing. The larger volume comes with a slightly larger profile under clothing — for patients prioritizing discretion over capacity, a standard-length pouch may be preferable.

How does the three-layer filter work?

The integrated filter contains activated charcoal between two protective layers. As gas accumulates in the pouch, it passes through the charcoal layer, which adsorbs odorous compounds before the gas exits through the outer filter membrane. The three-layer construction protects the charcoal from moisture and output contact, which extends filter effectiveness compared to single-layer filters. Coloplast states this design also reduces ballooning — the expansion of the pouch body from trapped gas that can make the pouch visible under clothing and cause the barrier seal to loosen at the edges.

What does the rotatable coupling allow that standard couplings do not?

Most two-piece coupling systems lock the pouch in a fixed orientation. The Assura rotatable coupling allows the user to spin the pouch to the preferred position — angled toward the hip, pointing downward, or oriented to the side — before the coupling clicks fully into the locked position. This is a clinically meaningful feature for patients who need the drain end or pouch body positioned differently depending on the activity (sleeping vs. standing vs. sitting), without the risk of partial engagement from forcing a fixed coupling into an off-axis orientation.

What is the spiral adhesive and why is it used on Assura barriers?

The spiral adhesive is Coloplast's proprietary barrier construction — the adhesive material is structured in a spiral pattern that combines two functional properties: mechanical adhesion to the skin and moisture absorption. The moisture absorption is clinically important because it draws perspiration and output moisture away from the peristomal skin, reducing maceration and irritation. The spiral structure maintains adhesive function even as the material absorbs moisture, preventing premature barrier failure that occurs with flat adhesive barriers when they become saturated.

Can I use this pouch with SenSura Mio Click barriers?

No. The Assura pouch is compatible with Assura barriers only. The coupling ring dimensions and locking mechanism of the Assura system are specific to Assura and are not interchangeable with SenSura Mio Click, SenSura Click, or any other Coloplast product line. Always match the color code on the pouch to the color code on the barrier when ordering both components of the system.

Why is a transparent pouch recommended over opaque for some patients?

Transparent pouches allow visual inspection of the stoma and output without removing the appliance. This is clinically preferred during the early post-operative period when stoma color (indicating blood supply), size, and output characteristics are monitored frequently. Transparent pouches are also preferred by patients who want to verify barrier placement during application, and by caregivers managing the pouching system for a patient who cannot self-monitor. Once a patient is confident in their stoma's appearance and their system management, many transition to an opaque pouch for additional privacy.

How do I know when to change a closed pouch?

A closed pouch should be changed before it is full — when it reaches approximately one-third to one-half capacity. The 570ml maxi volume gives more time between changes than standard closed pouches, but the timing still depends on individual output patterns. For patients with predictable colostomy patterns, the closed pouch is typically changed once or twice daily. Never wait until the pouch is completely full, as the weight of a full pouch can stress the barrier seal and increase the risk of leakage at the coupling ring.
