The HyFin® Vent Chest Seal Twin Pack is designed to provide critical wound management for chest injuries resulting from penetrating trauma. Supplied sterile and individually packaged, each chest seal acts as a mechanical barrier, adhering securely to the skin to seal wounds and help prevent the development of life-threatening conditions such as tension pneumothorax.
Each seal features three strategically placed vent channels that function to release trapped air and bodily fluids from the chest cavity while minimizing the risk of air re-entry. This vented configuration ensures one-way airflow, enhancing patient safety in dynamic and unpredictable environments.
Built for reliability in prehospital care, the seals maintain adhesion in the presence of blood, sweat, and body hair, offering consistent performance in challenging conditions. Their compact, twin-pack format enables responders to address both entry and exit wounds efficiently, or to have a spare on hand as needed.
With a durable adhesive backing and a non-invasive application method, the HyFin® Vent Chest Seal Twin Pack supports fast, effective treatment of chest trauma while forming a dependable mechanical barrier around the wound site. This product is a vital addition to emergency trauma kits for military, EMS, and civilian responders.
