The new HyFin® Vent Chest Seal provides an additional solution to the treatment of penetrating injuries to the chest by providing an occlusive chest dressing with a patented built-in vent that prevents airflow into the chest cavity during inspiration while allowing air to escape through the vent channel during exhalation. The HyFin® Vent Chest Seal is a 6 in. x 6 in. occlusive dressing with built-in vent that provides a superior occlusive chest dressing for those treatment protocols that call for the use of a dressing secured on 3-sides or a vented/valve type chest seal.

It features an enhanced adhesive gel formulation that creates a superior seal, even in the most adverse conditions. The seal has a transparent backing to allow placement directly over the wound and easily conforms to the patients chest. The seal is designed with a large, easily-visible red elliptical tab for single step peel-and-apply application that can also facilitate the burping of a wound if necessary. To ensure high quality performance, NAR packages each chest seal using its signature Red Tip Technology™ red tear notches in a rugged, easy-to-open, foil pouch. The HyFin® Vent Chest Seal is made in America and is 100% latex free.

    NAR HyFIN Vent Chest Seal

    Posted by Luis E Santos on 07 31 2018

    Great product but has an expiration date and has a life duration of 6 years. The one I recieved last week has a production date back to 2016, disappointed with this one. Rescue Essentials Reply: We believe that Luis is looking at the manufacture date, not the expiration date. Current lot was manufactured 11/2016, and bears an expiration date of 01/2022. We received these from the manufacturer on 7/5/2018.
