The Beacon™ Chest Seal is an advanced occlusive wound dressing designed to treat open chest wounds. Penetrating injuries to the chest that result in open chest wounds may lead to tension pneumothorax, the second leading cause of preventable death on the battlefield. Beacon™ Chest Seals are specifically designed with a medical grade hydrogel adhesive strong enough to adhere to skin that is exposed to blood, sweat, hair, sand or water.
