Clinical Summary: ConvaMax Superabsorber (ConvaTec REF 422566, 7.5 x 7.5 cm, single piece) is a three-layer non-adhesive superabsorbent wound dressing with a sodium polyacrylate (SAP) core that locks up to approximately 170 g of fluid per 100 cm of dressing under compression, an air-permeable waterproof backing, and a conformable wicking layer. It is indicated for moderately to highly exuding wounds where a low-profile, high-capacity exudate management dressing is required. Supplied sterile, latex-free, single-use; HSA Singapore listed; CE MDR and FDA 510(k) cleared.

Product Overview

ConvaMax Superabsorber Single Piece (7.5 x 7.5 cm, ConvaTec REF 422566) is a non-adhesive superabsorbent dressing engineered for moderate-to-high exudate management. Its three-layer construction comprises a soft conformable wicking layer in contact with the wound, a high-capacity superabsorbent polymer (SAP, sodium polyacrylate) core, and a waterproof but vapour-permeable non-woven backing that supports gaseous exchange while preventing strikethrough. Under compression, the SAP core retains exudate as a gel and resists fluid release back to the wound bed, supporting an optimal moist healing environment consistent with TIME wound bed preparation principles and EWMA exudate management guidance.

The 7.5 x 7.5 cm single-piece format is suited to small-to-medium exuding wounds, post-debridement defects, and sinus-margin applications. It is compatible as a primary or secondary dressing and can be layered with ConvaTec Aquacel Hydrofiber primary dressings to extend wear time on heavily exuding ulcers. The dressing is non-adherent and requires fixation by retention bandage, tubular bandage, tape, or compression system.

Clinical Indications

  • Venous leg ulcers with moderate to high exudate, including under multilayer compression bandaging (NICE CG168)
  • Pressure injuries Stage 2 to 4 with significant exudate (NPIAP/EPUAP/PPPIA)

Frequently Asked Questions

Q: How does ConvaMax differ from a foam dressing?
A: A polyurethane foam dressing absorbs primarily via capillary action and may release fluid back under compression. ConvaMax uses a sodium polyacrylate superabsorbent core that gels in place and locks fluid away, sustaining absorption under compression bandaging. This makes it the preferred secondary dressing for heavy exudate where foam alone causes strikethrough.

Q: When should I use the 7.5 x 7.5 cm size?
A: The 7.5 x 7.5 cm piece is indicated for small wound beds, post-debridement defects, sinus margins, or as a focal absorbent pad over a primary dressing. For larger ulcers, ConvaMax is also available in 10x10, 10x20, 15x15, 15x20, 20x20, 20x30, and 20x40 cm formats.

Q: Can ConvaMax be used under compression therapy in Singapore venous-ulcer protocols?
A: Yes. ConvaMax is specifically designed to retain exudate under compression and is commonly applied under short-stretch and multilayer compression systems used in Singapore restructured hospital outpatient and home-care wound services.

Q: Is the dressing compatible with NPWT (negative pressure wound therapy)?
A: ConvaMax is not used as a NPWT contact filler, but it is commonly used as a holding dressing during NPWT downtime or as a secondary absorbent layer in canister-free NPWT systems where high fluid capacity is required.

Q: Is HSA registration required for clinical purchase in Singapore?
A: ConvaMax is HSA-listed (medical device class B) and is procured by Singapore restructured hospitals, polyclinics, GP clinics, and home-care providers. EMIS+ supplies the genuine ConvaTec product with full traceability for institutional procurement and B2B clinic accounts.
