Convatec Natura+ InvisiClose Ostomy Pouch Clear 57mm (416419) – Anti Clog Filter, Clip Less Drainage | Box of 10

Product Overview

The ConvaTec Natura+ InvisiClose Drainable Ostomy Pouch (57mm, REF 416419) is a two-piece pouching system designed for ostomates requiring a mid-range flange diameter. The 57mm (2-1/4 inch) flange accommodates stomas with diameters commonly encountered in adult colostomy and ileostomy procedures when paired with compatible Natura cut-to-fit or pre-cut skin barriers. The InvisiClose tail closure mechanism replaces traditional external clamps with an integrated fold-and-lock system featuring Lock-it Pocket technology.

The transparent pouch body is manufactured from ConvaTec's proprietary soft, quiet, water-resistant film that minimises rustling during movement. An integrated charcoal filter with anti-clogging film layer provides continuous gas venting while blocking odour transmission. The two-piece snap-on coupling system delivers audible click confirmation upon secure attachment, enabling pouch changes without disturbing the underlying skin barrier and preserving peristomal skin health over extended wear periods.

Specifications

Clinical Indications

• Post-operative colostomy or ileostomy management requiring a 57mm flange two-piece drainable system for adult stoma diameters
• Patients transitioning from one-piece to two-piece systems who require the flexibility of independent pouch and barrier changes
• Clinical settings requiring transparent pouch construction for stomal output assessment including colour, volume, and consistency monitoring
• Ostomates with liquid to semi-formed output requiring frequent pouch emptying through a simplified clamp-free drainage mechanism
• Long-term home care where reduced pouch profile and quiet materials enhance quality of life and social confidence
• Institutional procurement for standardised ostomy care protocols within the ConvaTec Natura two-piece platform

Frequently Asked Questions

Q: What is the difference between the 45mm, 57mm, and 70mm flange sizes?

A: The flange size corresponds to the coupling diameter that connects the pouch to the skin barrier. The 57mm (2-1/4 inch) flange is the most commonly prescribed adult size, accommodating stoma diameters typically between 25mm and 45mm when paired with a cut-to-fit skin barrier. Flange selection should be based on stoma measurement performed by a qualified stoma care nurse, per Wound, Ostomy and Continence Nurses Society (WOCN) guidelines.

Q: How does the anti-clogging filter work?

A: The integrated charcoal filter uses a multi-layer design incorporating an anti-clogging film membrane. This film prevents liquid output from reaching and saturating the charcoal filter medium, maintaining gas venting performance throughout the wear period. The charcoal layer neutralises odour in released gas. Filter performance is optimised when the pouch is kept upright during gas release events.

Q: Can this pouch be worn during bathing or swimming?

A: The pouch material is water-resistant and can be worn during showering and bathing. For swimming, ConvaTec recommends covering the filter with the supplied filter cover sticker to prevent water ingress through the filter membrane. The snap-on coupling maintains seal integrity during water exposure. Patients should consult their stoma care nurse regarding activity-specific guidance, per International Ostomy Association (IOA) recommendations.

Q: How is this product registered for use in Singapore?

A: ConvaTec Natura+ ostomy pouches are registered with the Health Sciences Authority (HSA) of Singapore as Class A medical devices under the Health Products Act. They are available through authorised distributors including EMIS (Essential Medical International Supplies Pte Ltd). Institutional buyers and healthcare professionals may contact EMIS for procurement pricing and delivery scheduling.

Q: What skin barrier should I pair with this pouch for a newly formed stoma?

A: For newly formed stomas, ConvaTec recommends the Natura Stomahesive Moldable skin barrier with a 57mm flange. The moldable technology allows the barrier aperture to be shaped to fit irregular or swollen stomas without cutting, reducing the risk of peristomal skin exposure to stomal output. As the stoma matures and stabilises in size (typically 6-8 weeks post-surgery), transition to a pre-cut barrier may be appropriate based on clinical assessment.
