SFN DH Moldable Convex Wafer Baseplate 45 mm Medium Stoma Box of 10 404593

Product Overview

The ConvaTec SUR-FIT Natura Durahesive Moldable Convex Skin Barrier with Flange (404593) 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 facilitate a more reliable seal, which is essential in managing liquid and semi-liquid effluent from ileostomies and urostomies.

ConvaTec Moldable Technology eliminates the need for scissors or measuring templates. The user simply rolls the starter hole outward to match the exact stoma diameter (22–33 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. The SUR-FIT Natura snap-lock flange system provides audible confirmation of a secure pouch connection via colour-coded coupling rings.

Specifications

Clinical Indications

• Post-surgical colostomy, ileostomy, or urostomy management requiring a two-piece pouching system with convex barrier support
• Flush or retracted stomas where a flat skin barrier fails to maintain adequate seal integrity
• Patients with liquid or semi-liquid effluent who require a hydrocolloid barrier that swells to prevent undermining (Durahesive turtlenecking)
• Medium-sized stomas (22–33 mm) in patients with peristomal skin folds or irregular body contours
• Long-term ostomy care in community, outpatient, and home-nursing settings in Singapore and South-East Asia

Frequently Asked Questions

Q: What stoma sizes does the 404593 wafer accommodate?
A: The 404593 accommodates medium stomas ranging from 22 mm to 33 mm (7/8″ to 1¼″). The moldable starter hole rolls outward to conform precisely to the stoma base diameter. For stomas larger than 33 mm, consider the 404594 (57 mm flange, large) variant.

Q: How does Durahesive differ from Stomahesive formulations?
A: Durahesive barriers are engineered to swell upward (turtleneck) on contact with liquid output, making them optimal for ileostomies and urostomies. 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.

Q: Which pouches are compatible with the 45 mm flange?
A: All SUR-FIT Natura pouches carrying a matching 45 mm (1¾″) coupling ring and yellow colour code are compatible. The snap-lock system provides an audible click to confirm secure attachment. Always verify the flange colour code before connecting a pouch.

Q: Can I purchase this product for a healthcare facility in Singapore?
A: Yes. The ConvaTec 404593 is registered with the Health Sciences Authority (HSA) of Singapore and available for B2B procurement through EMIS. Bulk pricing, standing-order arrangements, and institutional quotations are available for hospitals, nursing homes, and home-care agencies.

Q: How often should a convex skin barrier be replaced?
A: The Wound, Ostomy and Continence Nurses Society (WOCN) recommends changing skin barriers 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 indicate an earlier change is warranted.
