The HyFin® Vent Compact Chest Seal Twin Pack is a high-performance solution for treating open and/or tension pneumothorax caused by penetrating chest trauma. Designed for quick and effective management, it features two vented chest seals packaged compactly for ease of transport. The cutting-edge design incorporates 3 vented channels, allowing air to escape during exhalation while preventing air from entering the injury site during inhalation.

Ideal for first responders, military personnel, and emergency medical kits.
