DAMAI dissolvable polyurethane nasal hemostatic dressing functions as a high-performance intranasal splint for postoperative nasal hemostasis and wound stabilization. Multiple size options are available to fit different nasal anatomies.

Fabricated from medical-grade synthetic polyether-polyurethane, it dissolves naturally within approximately 7 days, eliminating painful manual removal and secondary mucosal injury.

Optimized for minimally invasive ENT procedures such as septoplasty, endoscopic sinus surgery, and nasal polypectomy, it delivers calibrated elastic compression for stable hemostasis and dependable anti-adhesion protection.

Completely free of animal-derived raw materials, it reduces allergy risks and simplifies clinical operations for ENT surgeons.

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

1. Aseptic access: Open sterile package and take out dressing with forceps, maintaining full aseptic conditions.
2. Trim to fit: Cut the sponge into proper size matching surgical wounds and nasal cavity anatomy.
3. Place into position:Option 1 — Direct placement: Apply directly onto bleeding wound for compression hemostasis.Option 2 — Presoaked placement: Soak before implantation to realize local drug sustained 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.
