Why Choose Natura® Moldable Durahesive® Barrier

This barrier combines moldable convenience that eliminates cutting and measuring with Durahesive® extended-wear technology specifically engineered to resist breakdown from liquid or high-output effluent. The moldable "turtleneck" seal creates 360° protection around the stoma to prevent undermining leaks, while the erosion-resistant Durahesive® formula maintains adhesion longer than standard hydrocolloids—even when exposed to constant moisture from ileostomy or urostomy output. The secure Natura® coupling features an audible "click" for confident pouch attachment, and the scissors-free design speeds barrier changes while reducing anxiety about proper sizing.

• Travel situations where scissors aren't convenient

Flush or Slightly Retracted Stomas:

• Turtleneck seal helps prevent undermining on flush stomas
• Gentle molded fit accommodates slight retraction
• Alternative or complement to convex barriers for mild cases

Moist or Challenging Skin with Liquid Output:

• Combination of moisture-tolerant adhesion AND liquid-resistant formula
• Protective barrier against liquid effluent damage
• Extended wear even in challenging moisture conditions

Understanding Durahesive® Technology

What is Durahesive®?

Durahesive® is ConvaTec's advanced hydrocolloid formulation specifically engineered for ostomies with liquid or high-output effluent:

Enhanced Erosion Resistance: The formulation resists breakdown when exposed to liquid output—maintaining structural integrity and adhesion longer than standard hydrocolloids including Stomahesive®.

Moisture Management: Can absorb and manage higher moisture levels without losing adhesive properties—critical for liquid ileostomy or continuous urostomy output.

Extended Wear Time: Typical wear time of 5-7 days even with liquid output, compared to 3-5 days for standard hydrocolloids in the same conditions.

Skin Protection: Creates reliable barrier between caustic liquid effluent and vulnerable peristomal skin, reducing chemical irritation and breakdown.

Adhesion Stability: Maintains consistent adhesion throughout wear period despite constant moisture exposure—prevents premature edge lift or erosion.

Durahesive® vs. Stomahesive®

Durahesive® (This Product):

• Engineered for liquid/high-output effluent
• Superior erosion resistance in high-moisture situations
• Longer wear time with liquid output
• Best for ileostomy and urostomy
• Slightly higher cost but extended wear compensates
• Essential for challenging liquid output situations

Stomahesive®:

• General-purpose hydrocolloid formula
• Adequate for formed to semi-formed output
• Standard wear time with typical output
• Best for colostomy with formed output
• More economical for lower-moisture situations
• Good baseline option for standard needs

Choosing Between Them:

• Choose Durahesive® if: You have ileostomy with liquid output, urostomy, high-output ostomy, or experience frequent barrier erosion
• Choose Stomahesive® if: You have colostomy with formed output, lower-output situations, or standard moisture conditions

Many ileostomy users find Durahesive® essential for adequate wear time, while colostomy users often do well with standard Stomahesive®.

Understanding Moldable Technology

How Moldable Barriers Work:

Unlike traditional cut-to-fit barriers requiring scissors, moldable barriers feature a soft, pliable opening that shapes by hand:

The Material: The inner ring is extra-soft, elastic hydrocolloid that stretches and molds without tearing or losing adhesive properties.

The Process: By rolling or pressing the opening with fingers, users create a custom-sized aperture matching their specific stoma—round, oval, or irregular.

The "Turtleneck" Effect: When properly molded, the opening creates a gentle rolled edge extending slightly upward around the stoma base, like a turtleneck collar. This provides extra protection against undermining—critical for liquid output.

Advantages Over Cut-to-Fit:

• No scissors, measuring guides, or templates needed
• Faster barrier changes (no cutting time)
• More forgiving—can remold if not perfect first time
• Adapts to slight daily variations in stoma size
• Safer for users with vision or dexterity challenges
• More convenient for travel

Natura® 45mm (1¾") Coupling System

This barrier uses ConvaTec's Natura® 45mm (1¾") coupling—one of the most common flange sizes.

Compatible With:

• ConvaTec Natura® 45mm drainable pouches (essential for ileostomy)
• ConvaTec Natura® 45mm urostomy pouches (for urinary diversion)
• ConvaTec Natura® 45mm closed pouches
• All Natura® 45mm pouch styles

NOT Compatible With:

• Other ConvaTec flange sizes (57mm, 70mm)
• Other manufacturers' systems (Hollister, Coloplast, etc.)
• Hollister New Image™ 1¾" (different coupling mechanism)

⚠ Important: While both ConvaTec and Hollister make 1¾" (45mm) flanges, they use different coupling mechanisms and are NOT interchangeable.

Usage & Application

Preparing the Barrier:

1. Remove barrier from packaging
2. Warm barrier between hands for 30-60 seconds to make moldable opening more pliable
3. The warmer the barrier, the easier it molds

Molding the Opening:

1. Examine your stoma and estimate its size (must be within 7/8"–1¼" range)
2. Place fingers inside the moldable opening
3. Gently stretch and roll the opening outward to enlarge it to approximately match stoma size
4. For oval stomas, stretch more in one direction to create oval shape
5. Create opening slightly larger than stoma (about ⅛" or 2-3mm gap all around)
6. If opening becomes too large, press edges inward to reduce size
7. Can remold multiple times until desired fit is achieved

Application:

1. Cleanse and dry peristomal skin thoroughly
2. Remove paper backing from barrier
3. Center molded opening over stoma, ensuring ⅛" gap around entire circumference
4. Press barrier onto skin, starting at stoma and working outward
5. Smooth barrier with hand for 30-60 seconds, allowing body heat to activate adhesion
6. Pay special attention to edges, pressing firmly
7. The moldable opening should form gentle "turtleneck" collar around stoma base

Coupling the Pouch:

1. Align pouch flange with barrier coupling ring
2. Press around entire ring perimeter until you hear/feel audible "click"
3. Gently tug pouch to confirm secure attachment
4. If using belt, thread through belt tabs and adjust for comfortable support

For Liquid Output Users:

• Empty pouch when ⅓ to ½ full—don't let it get too heavy
• Monitor barrier edges more frequently with liquid output
• Watch for early signs of erosion or undermining
• Consider protective barrier strips or paste for extra security if needed

When to Replace:

• Typical wear time: 5-7 days with liquid output (longer than standard hydrocolloids)
• Replace if barrier edges begin to lift or erode
• Replace if leakage or undermining occurs
• Replace if skin irritation develops
• Some users achieve longer wear with Durahesive® than they did with previous products

Moldable Range: 7/8"–1¼" (22–32mm)

Understanding the Range:

Minimum Opening (7/8" / 22mm):

• Smallest stoma size this barrier accommodates
• Can be molded down to this size from the starting diameter

Maximum Opening (1¼" / 32mm):

• Largest stoma size this barrier accommodates
• Cannot be stretched beyond this diameter safely
• If your stoma measures larger than 1¼", you need a different product

Finding Your Size:

• Measure stoma at widest point using stoma measuring guide
• Stoma must measure between 7/8" and 1¼" to use this product
• Mold opening slightly larger than actual stoma (about ⅛" gap)
• If stoma is larger or smaller, consult ostomy nurse for alternatives
