WoundClot® EMS Hemostatic Gauze (Catalog 101481901) is a next-generation, non-oxidized non-regenerated cellulosic (NONRCS) Z-Fold hemostatic dressing measuring 3 in × 39 in. When applied to a bleeding wound, it converts from a dry gauze into a thick, adherent 3D gel matrix that concentrates clotting factors and absorbs up to 2,500% of its weight in blood — remaining actively absorbent for up to 24 hours — with an FDA 510(k) clearance and 5-year shelf life.

How WoundClot Works
WoundClot EMS Hemostatic Gauze uses a patented non-oxidized, non-regenerated cellulosic (NONRCS) structure that undergoes a rapid phase change on blood contact. Within seconds, the dry gauze transforms into a thick, tenacious, expanding 3D gel matrix that adheres to wound tissues, conforming to irregular wound shapes and filling wound tracts. This gel structure provides hemostasis through four simultaneous mechanisms:
- Rapid fluid absorption: Absorbs up to 2,500% of its weight in blood — actively removing fluid from the wound to reduce bleeding volume.
- Mechanical wound sealing: The expanding 3D gel physically seals the wound surface and wound tract, providing a mechanical barrier to blood flow.
- Platelet and clotting factor concentration: The gel matrix aggregates platelets, red blood cells, and clotting factors at the wound site, creating an environment conducive to rapid clot formation.
- Coagulation cascade activation: WoundClot's functional molecular groups convert Plasma Thromboplastin Antecedent (Factor XI) and Hageman factor (Factor XII) from inactive to active forms (XIa and XIIa), directly accelerating the intrinsic coagulation pathway.
Unlike kaolin-based hemostatics (e.g., Combat Gauze) or chitosan-based products, WoundClot does not rely on an exothermic reaction or require irrigation for removal — the gel structure dissolves in wound fluid over time and does not cause rebleeding when removed. It remains actively absorbent for up to 24 hours, providing a sustained hemostatic effect through extended evacuation timelines.
The 3 in × 39 in Z-Fold format is EMS-optimized for efficient wound packing — providing the length needed to pack deep wound tracts and channel wounds from a single strip, eliminating the need to piece together multiple smaller dressings. The Z-Fold packaging allows rapid deployment directly into the wound with controlled, sequential packing from the wound base to the surface.
Application Instructions
- Apply direct pressure while preparing the dressing.
- Open packaging and unfold the Z-Fold strip.
- Pack the gauze tightly into the wound, starting at the bleeding source and working toward the wound surface.
- Maintain firm, direct pressure per protocol while the gauze hydrates and forms its 3D gel matrix.
- If bleeding persists, add additional WoundClot or re-pack to target the bleeding source.
- Secure with a pressure bandage and monitor during transport. Remove within 24 hours or prior to wound closure.
