Hyfin Vent Chest Seal by North American Rescue NAR100029

HyFin Vent Chest Seal Twin Pack from North American Rescue sets the standard for the treatment of penetrating injuries to the chest. Providing two vented chest seals in one unique package for treatment of both entry/exit or multiple penetrating injuries to the chest. The new HyFin Vent Chest Seal design provides 3-vented channels that prevent airflow into the chest cavity during inspiration while allowing air to escape through the vent channels during exhalation. The 3-vent channels allow blood to escape and also provide a backup fail-safe system, as even if two of the three channels become obstructed, the vent will remain fully operational.
