Curaplex® Vented Tactical Occlusive Chest Seals (T.O.C.S.) are designed to manage and treat open chest wounds caused by gunshots or other penetrating trauma. Each pack includes two seals: one H*VENT, which is designed to relieve pressure from an open chest wound due to air (pneumothorax) or bodily fluid (hemothorax), as well as one non-vented dressing. The large pull tabs and flexible material are used to help facilitate application and repositioning on the trauma site, if required. This seal features a compact size to fit neatly in most first aid kits.


  • Compact size fits into most first aid kits and trauma packs for quick access
  • Secure adhesion for conditions such as excessive bleeding or heavy perspiration
  • Large pull tabs offer the ability to reseal and burp the wound
  • Dome design gives quick indication of air or fluid leaving the chest (fills up), or when the seal is in place (sucks down)
  • Multi-directional, vented dressing allows the fluids to “drain towards gravity,” allowing the patient to be transported on their side
  • Large vent openings in the H*VENT allow for visual monitoring of the wound
  • 6 ports ensure a backup-fail-safe system; even if 5 become obstructed, the vent will remain fully operational
  • Unique dome membrane design creates a complete seal around the wound area, ensuring a complete seal around the wound and reducing the risk of air or fluid finding alternate paths
  • Proven, in internal testing, to retain a seal during inhalation and maintain a sustainable negative pressure (below ambient pressure) within the pleural space
  • Latex-free
  • Made in the U.S.A.
