The Durahesive hydrocolloid swells on contact with liquid effluent to protect peristomal skin, and the SUR-FIT Natura flange system audibly clicks into any compatible SUR-FIT Natura pouch. Supplied 10 per box; manufactured under ISO 13485 with CE Mark (EU MDR 2017\/745) and FDA registration.\u003c\/div\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe SUR-FIT Natura Durahesive Convex Moldable Flexible Wafer (REF 404594, Large) is a two-piece ostomy skin barrier designed for patients with retracted, flush, or peristomal dermal folds that compromise the seal of a flat skin barrier. The convex dome applies gentle pressure around the stoma, pushing the stomal base outward and improving effluent drainage into the pouch rather than under the skin barrier. Moldable Technology replaces conventional cut-to-fit scissoring with a finger-shaped opening that rolls back on itself and hugs the stomal base, reducing the risk of leakage from an oversized or irregular cut and eliminating sharp edges that can abrade stomal mucosa.\u003c\/p\u003e\n\u003cp\u003eDurahesive is a pectin, gelatin and carboxymethylcellulose hydrocolloid formulated to absorb liquid effluent and \"turtleneck\" around the stoma, creating a more secure seal for ileostomates and high-output stomas. The two-piece design with the SUR-FIT Natura flange allows the pouch to be changed independently of the barrier, which is clinically relevant for patients who change pouches multiple times daily but wear the same barrier for 3-7 days.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%;\" cellspacing=\"0\" cellpadding=\"6\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eConvatec (UK)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eProduct\u003c\/th\u003e\n\u003ctd\u003eSUR-FIT Natura Durahesive Convex Moldable Flexible Wafer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eReference Number\u003c\/th\u003e\n\u003ctd\u003e404594 (Large)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eFlange Size\u003c\/th\u003e\n\u003ctd\u003e57 mm (2 1\/4 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eMould-to-Fit Stoma Opening Range\u003c\/th\u003e\n\u003ctd\u003e33-57 mm (1 1\/4 to 1 3\/4 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eSkin Barrier\u003c\/th\u003e\n\u003ctd\u003eDurahesive hydrocolloid (pectin, gelatin, carboxymethylcellulose matrix)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eProfile\u003c\/th\u003e\n\u003ctd\u003eConvex (built-in dome for retracted or flush stomas)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eFlexibility\u003c\/th\u003e\n\u003ctd\u003eFlexible collar; adapts to peristomal body contours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eCoupling\u003c\/th\u003e\n\u003ctd\u003eSUR-FIT Natura mechanical flange with audible locking clicks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eLatex Content\u003c\/th\u003e\n\u003ctd\u003eLatex-free construction\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003ePackaging\u003c\/th\u003e\n\u003ctd\u003e10 wafers per box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"background: #f0f4f8; text-align: left;\"\u003eRegulatory\u003c\/th\u003e\n\u003ctd\u003eFDA-registered medical device; CE Mark under EU MDR 2017\/745; ISO 13485 quality-management certified; ISO 8670 ostomy-product standard; HSA Singapore registered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eClinical Indications and Key Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIleostomy, colostomy or urostomy patients with a retracted or flush stoma where a flat skin barrier fails to maintain a seal against effluent\u003c\/li\u003e\n\u003cli\u003eObese patients or those with abdominal scarring and peristomal skin creases where convexity is required to level the peristomal plane\u003c\/li\u003e\n\u003cli\u003ePatients with stomal diameters between 33 mm and 57 mm requiring mould-to-fit sizing without scissors, particularly older adults with reduced manual dexterity\u003c\/li\u003e\n\u003cli\u003eParastomal hernia management (in combination with a support belt) where convex wafers accommodate the protrusion without dislodging\u003c\/li\u003e\n\u003cli\u003eHigh-output ileostomy where Durahesive's moisture-activated swelling extends barrier wear time and reduces peristomal skin irritation\u003c\/li\u003e\n\u003cli\u003eTwo-piece appliance users who prefer independent pouch changes while preserving skin barrier integrity over multi-day wear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhen is a convex wafer clinically indicated rather than a flat wafer?\u003c\/h3\u003e\n\u003cp\u003eConvexity is indicated when the stoma is retracted below the peristomal skin plane, flush with the plane, or surrounded by creases or scars that prevent a flat wafer from sealing. Wound, Ostomy and Continence Nurses Society (WOCN) and World Council of Enterostomal Therapists (WCET) guidance recommends assessment by a stoma therapist to confirm convexity prescription, including consideration of parastomal hernia risk before long-term convex use.\u003c\/p\u003e\n\u003ch3\u003eWhat advantage does Moldable Technology offer over cut-to-fit?\u003c\/h3\u003e\n\u003cp\u003eMoldable Technology eliminates the scissoring step, reducing the risk of sharp-edge trauma to stomal mucosa and producing a better seal for irregular or oval-shaped stomas. The barrier is rolled back with the fingers to form the opening, which then rebounds slightly to hug the stomal base. This has been shown to reduce leakage episodes in multi-centre observational data (Convatec Moldable Technology clinical evidence portfolio).\u003c\/p\u003e\n\u003ch3\u003eHow should the Durahesive convex wafer be changed?\u003c\/h3\u003e\n\u003cp\u003eRemove the used wafer by supporting the peristomal skin and peeling gently from the top down, using an adhesive remover if required. Clean the peristomal skin with water (avoid oil-based wipes, which impair adhesion), dry thoroughly, mould the opening to 2-3 mm larger than the stoma base, and apply with gentle pressure for 30-60 seconds to activate the hydrocolloid. Click the compatible SUR-FIT Natura pouch onto the flange until the audible lock is confirmed.\u003c\/p\u003e\n\u003ch3\u003eWhich pouches are compatible with the 57 mm flange?\u003c\/h3\u003e\n\u003cp\u003eOnly Convatec SUR-FIT Natura pouches with the matching 57 mm flange code will couple reliably. Cross-fitting with other manufacturers' flanges is not supported and may compromise the seal.
