This valve version of the SAM Chest Seal is an occlusive dressing for open chest wounds that features a one-way valve when its cap is removed. The valve allows air to flow out of the chest cavity at low resistance while preventing ingress and prevents internal blockage. The dressing is occlusive with the cap in place.
