Abstract
A sterile two-part wound dressing for surgical drainage tube and chest thoracostomy tubes that is designed to create a seal around the chest tube during tube removal decreasing the risk of air leak and post-pull iatrogenic pneumothorax, to absorb exudate from the wound, and to provide a water-resistant covering to limit contamination of the wound during healing.
