Hyfin Vent Chest Seal Twin Pack

Immediate chest decompression for penetrating trauma

The Hyfin Vent Chest Seal Twin Pack is engineered to prevent and manage open and tension pneumothorax resulting from penetrating chest trauma. Each seal is individually packaged to permit treatment of both entry and exit wounds, or to allow one to be held in reserve. Designed for medics, EMTs, battlefield corpsmen, law enforcement medics, and trauma surgeons, the seals enable fast, single step application to stop external airflow into the chest while managing internal pressure. The result is rapid containment of a life threatening condition, with the flexibility to address multiple injuries on a single casualty or multiple patients in mass trauma events.

Patented three channel vent, burp capable application

This twin pack features a patented design with three channel pressure relief vents that block air entry during inhalation, while allowing egress during exhalation to reduce the risk of tension physiology. The large red tab enables a peel and apply motion that is easy to grasp under stress, and it allows controlled burping of the wound if needed. Device dimensions are compact, the seal surface measures approximately 6 in by 6 in excluding the tab, and the folded packaged size keeps it compact for pouches and trauma kits. The design is focused on speed, effectiveness, and predictable venting behavior.

Advanced adhesive and rugged, field ready build quality

Adhesive performance is critical for chest seals, and this product uses advanced adhesive technology formulated to form a durable seal on sweaty, damp, or hairy skin. Each seal is lightweight at approximately 2.5 oz, and packaged unfolded dimensions fit compactly into standard trauma kit pockets. The materials resist environmental contamination and maintain tack in adverse conditions, so first responders can apply the seal confidently under wet weather or high exertion. Built for repeated training and real world use, the sealed pouch protects the device until needed.

Dual pack versatility for operational and civilian scenarios

Including two individually packaged chest seals offers clear operational advantages, enabling treatment of both an entry and an exit wound, or keeping a spare on hand for evolving scenes. The twin pack is ideal for military patrol medics, tactical teams, ambulance crews, and emergency department fast teams, while also fitting in workplace emergency kits, school medical rooms, or public access trauma kits. Lightweight and compact, the pack integrates easily into IFAKs, patrol bags, and vehicle trauma kits where immediate chest management may be required.
