The SAM chest seal with valve is engineered to treat, seal, and reseal open chest wounds under emergency conditions. The one-way valve allows trapped air to escape from the pleural cavity while preventing air from being drawn back in during breathing. The self-adhering design maintains its bond on skin contaminated with blood, sweat, and body hair, which are typical conditions at penetrating chest trauma scenes.
Compliance Summary: The SAM chest seal is a medical device for emergency pneumothorax management. The valved design provides controlled air release from the pleural space while maintaining occlusive wound protection. Training in chest seal application and pneumothorax recognition is required.
What does the valve do?
The one-way valve allows air trapped in the pleural space to escape during exhalation, preventing the build-up of pressure that causes tension pneumothorax. During inhalation, the valve closes to prevent external air entering the chest cavity through the wound. This controlled venting mechanism maintains respiratory function while protecting the wound.
Can I reseal the SAM chest seal after inspection?
Yes. The SAM chest seal is designed to be lifted for wound inspection and resealed without replacing the device. The adhesive maintains its bond through multiple applications, allowing clinical reassessment of the wound without sourcing a replacement seal. This reseal capability is particularly valuable during extended casualty management before hospital transfer.
