The DAMAI dissolvable polyurethane nasal hemostatic dressing is a high-performance intranasal splint engineered for post-surgical nasal hemostasis and wound support. Optimized for minimally invasive ENT procedures, it delivers controlled compression, reliable anti-adhesion protection, and improved patient safety with zero animal-derived ingredients.

Made from medical-grade synthetic polyether-polyurethane, the dressing dissolves naturally within approximately 7 days, eliminating painful manual removal and the risk of secondary tissue injury.

• Controlled Compression & Reliable Hemostasis: The porous elastic structure provides stable compression on surgical wounds, compressing small blood vessels, accelerating platelet aggregation, and achieving fast hemostasis.
• Safe, Predictable Dissolution — No Manual Removal: The 100% synthetic polyurethane material safely degrades into carbon dioxide and water. Residual fragments drain spontaneously via nasal mucus flow, avoiding the secondary bleeding and mucosal injury associated with traditional packing removal.
• Effective Anti-Adhesion & Scar Reduction: Separates mucosal surfaces after surgery to prevent tissue adhesion, turbinate lateralization, and excessive scar formation, effectively reducing common postoperative complications following sinus and septum operations.
• Excellent Biocompatibility, Low Allergy Risk: Free of collagen, gelatin, chitosan, and other animal- or shellfish-derived raw materials. Minimizes sensitization risk for seafood-allergic patients, with proven bio-inert clinical performance.
• Flexible, Ready-to-Use Clinical Operation: The soft, pliable material can be freely trimmed and shaped to fit diverse nasal anatomies and irregular wound cavities. No pre-mixing or pre-wetting is required for direct intraoperative use.

1. Aseptic access: Open the sterile package and remove the dressing with forceps, maintaining full aseptic conditions.
2. Trim to fit: Cut the sponge to the appropriate size to match the surgical wounds and nasal cavity anatomy.
3. Place into position:
   • Option 1 — Direct placement: Apply directly onto the bleeding wound for compression hemostasis.
   • Option 2 — Presoaked placement: Soak before implantation to achieve local sustained drug release for mucosal healing.
4. Post-operative management: Allow natural dissolution; residual fragments may be cleared by saline irrigation or suction 3–7 days after surgery.
