The PerSys S.O.S.™ (Secure Occlusive Seal) is an advanced occlusive dressing developed for the treatment of open chest wounds and for the prevention of tension pneumothorax.
Best-in-class adhesion for any situation
The PerSys S.O.S.™ utlizes an ultra-strong, medical-grade hydrogel adhesive which clings to skin despite blood, sweat, hair, sand, or water. The dressing’s four vent design allows for one-way airflow out of the chest cavity during exhalation, while preventing airflow into the chest cavity during inhalation. The vents provide unobstructed function, despite exposure to blood and environmental debris.
Small in size, secure in strength.
At 4" by 6", the S.O.S. debuted as one of the smallest chest seals on the market, but makes no compromise in adhesive strength or effectiveness.
