Coloplast Assura New Generation Two-Piece Midi Transparent Closed Pouch with Filter
SKUs: 12344 | 12345 | 12346 | 7" / 275ml | Sold 30/Pack | Made in USA | FSA Eligible | Latex Free
The standard-volume closed-end pouch in the Coloplast Assura New Generation line — 7" (275ml) transparent film with a three-layer integrated filter that neutralizes odor and prevents ballooning. The rotatable mechanical coupling allows the pouch to be positioned before locking, and an audible click confirms secure attachment to the Assura barrier. Spiral adhesive on the barrier provides secure, moisture-absorbing adhesion. Anatomically shaped, water-repellent soft backing. Color-coded in three flange sizes. Barrier not included. 30/pack.

Clinical FAQs
What is the difference between the Assura midi (12344) and the Assura maxi (12374) closed pouches?
The midi (7"/275ml) and maxi (8.5"/570ml) are the same pouch design — same three-layer filter, same rotatable coupling, same spiral adhesive, same transparent film, same water-repellent backing, same color-coded flange sizes. The only difference is volume and length. The midi is appropriate for patients with predictable colostomy output who change the pouch once to twice daily and prefer a lower-profile, more discreet fit under clothing. The maxi is appropriate for patients with higher output volume, those who want a longer interval between changes, or those who prefer a larger capacity reserve during extended activities. Both 30-pack quantities are the same price point — choose based on change frequency and lifestyle preference.
When is a transparent pouch preferred over an opaque one?
Transparent film allows visual inspection of the stoma and output without removing the appliance. Clinically, transparent pouches are preferred during the post-operative period when stoma color (indicating circulation), size, and output characteristics are actively monitored. They are also preferred by patients who track urine-like liquid output from a colostomy for color changes, by caregivers managing the appliance for a patient who cannot self-monitor, and by anyone who wants to verify stoma position and barrier placement during application. Many patients transition to an opaque pouch (such as the Assura beige closed pouch) for greater privacy once they are comfortable and no longer need visual monitoring at each change.
How does the three-layer filter prevent ballooning?
Gas accumulates in any closed-end pouch between output events. Without a filter, trapped gas inflates the pouch body — creating a visible bulge under clothing and potentially loosening the barrier seal at the edges from the outward pressure. The three-layer filter contains activated charcoal between two protective membrane layers. Gas passes through the charcoal layer, which adsorbs odorous compounds before the gas exits through the outer membrane. The charcoal protection layers prevent moisture and output from contacting the charcoal and saturating it prematurely. The result is a continuously vented pouch that maintains a flat profile and controls odor passively throughout the wear period.
How does the rotatable coupling work and why is it useful?
The Assura coupling ring allows the pouch to be rotated to the preferred angle before the locking mechanism engages. The user aligns the drain end of the pouch toward the hip, downward, or to whichever position best suits their body posture or activity — then presses the coupling fully into the locked position with an audible click. This is a meaningful usability advantage over fixed-orientation couplings: patients can orient the pouch comfortably for standing, lying, or seated positions without having to reposition the whole appliance. The coupling can also be repositioned for left- or right-handed access, accommodating users who need to approach from a specific side.
Can this pouch be used with Assura AC or SenSura Mio Click barriers?
No. The Assura New Generation pouch is specifically compatible with Assura (original and New Generation) skin barriers in the matching flange size. It is not compatible with Assura AC, SenSura, SenSura Mio Click, or any other Coloplast barrier line, which use different coupling ring dimensions and locking mechanisms. Always confirm the barrier system before ordering — mixing pouch and barrier components from different systems results in improper coupling and leakage risk. Match the color code on the pouch to the color code on the Assura barrier.
What does "soft water-repellent backing" mean for active patients?
The soft backing fabric on the Assura pouch has two functions: it provides a comfortable, quiet surface against skin and clothing (reducing the rustle common with plain plastic pouches), and its water-repellent treatment allows the pouch to dry quickly after showering or swimming. The water-repellent surface sheds surface water rather than absorbing it, so the pouch body dries within minutes after water exposure. The filter should not be deliberately submerged for extended periods; for prolonged swimming, a waterproof filter cover may be used to protect filter function and removed after water activities.
How do I know when to change the pouch?
A closed-end pouch should be changed before it is full — typically at approximately one-third to one-half capacity. The 275ml midi volume gives reasonable capacity between changes for most colostomy patients with predictable output. With the transparent film, the output level is visible at all times without removing the pouch, making it easy to judge the right moment to change. Never allow the pouch to overfill — the weight and pressure of a full pouch can stress the coupling ring connection and strain the barrier adhesion at its edges.
