Its Durahesive hydrocolloid formulation swells on contact with liquid output (turtlenecking effect), creating a secure peristomal seal without cutting. The device is indicated for colostomy, ileostomy, and urostomy patients requiring convex barrier support for flush or retracted stomas.\u003c\/div\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe ConvaTec SUR-FIT Natura Durahesive Moldable Convex Skin Barrier with Flange (404594) is an advanced ostomy baseplate engineered for ostomates whose stoma sits flush with or below the skin surface. The convex profile applies gentle pressure around the peristomal area to improve stoma protrusion and promote a more reliable seal, which is critical in managing liquid and semi-liquid effluent from ileostomies and urostomies.\u003c\/p\u003e\n\u003cp\u003eConvaTec Moldable Technology eliminates the need for scissors or templates. The user simply rolls the starter hole outward to match the exact stoma diameter (33–45 mm range), achieving a custom fit that minimises exposed skin and reduces the risk of peristomal moisture-associated skin damage (MASD). The white fabric tape collar increases flexibility and comfort under clothing while securing the barrier to the skin. Once attached, the SUR-FIT Natura snap-lock flange system provides audible confirmation of a secure pouch connection.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"border-collapse: collapse;

Stomahesive barriers are designed for formed-to-semi-formed output typical of many colostomies. The World Council of Enterostomal Therapists (WCET) recommends matching barrier chemistry to output consistency for optimal peristomal skin protection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I size the moldable opening correctly?\u003c\/strong\u003e\u003cbr\u003eA: Place the starter hole over the stoma and gently roll the opening outward with your fingers until it matches the stoma base diameter. No scissors or measuring guide is required. ConvaTec Moldable Technology allows the hydrocolloid edge to conform snugly around the stoma, minimising the gap between the barrier and the mucocutaneous junction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the 57 mm flange wafer be used with any SUR-FIT Natura pouch?\u003c\/strong\u003e\u003cbr\u003eA: The 57 mm flange is compatible with all SUR-FIT Natura pouches that carry a matching 57 mm (2¼″) coupling ring. The system uses a colour-coded flange identification (green for 57 mm) and provides an audible click to confirm secure attachment. Always verify the flange colour code before connecting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this product available for purchase by healthcare facilities in Singapore?\u003c\/strong\u003e\u003cbr\u003eA: Yes. This ConvaTec 404594 wafer is registered with the Health Sciences Authority (HSA) of Singapore and available for B2B procurement through EMIS. Bulk pricing and standing-order arrangements are available for hospitals, nursing homes, and home-care agencies. Contact EMIS for institutional quotations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should the skin barrier be changed?\u003c\/strong\u003e\u003cbr\u003eA: According to the Wound, Ostomy and Continence Nurses Society (WOCN), skin barriers should be changed when leakage occurs or at regular intervals based on individual assessment—typically every 3 to 7 days for convex barriers. Premature erosion, lifting edges, or peristomal irritation are signs that a change is needed sooner.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What is Convatec SFN DH Moldable Convex Wafer Baseplate 57 mm Large Stoma Box of 10 404594 used for?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Convatec SFN DH Moldable Convex Wafer Baseplate 57 mm Large Stoma Box of 10 404594 by Convatec is a skin barrier\/baseplate that adheres around the stoma to create a secure seal and protect peristomal skin from stoma output.
