About SEAL: The Story Behind the Hemostatic Wound Spray Redefining Bleeding Control


When seconds matter, control matters more.
That belief drives everything we do at BC3 Technologies, the parent company behind SEAL Hemostatic Wound Spray, the first and only FDA-cleared chitosan aerosol spray designed for external bleeding control.
What began as a mission to simplify bleeding management for first responders has evolved into a new standard in emergency care that is changing how professionals and everyday people respond to trauma.
From Concept to Clearance: The BC3 Story
BC3 Technologies was founded with a clear purpose: to bridge the gap between advanced medical science and real-world usability in trauma response.
Our founders, a team of biomedical engineers and emergency medicine experts, saw a critical gap in how bleeding was being managed outside hospital walls. Traditional methods like gauze packing and powders worked, but they were slow, inconsistent, and often impractical under stress.
So BC3 asked a simple question with revolutionary implications:
What if life-saving hemostatic technology could be applied as easily as a spray?
That question led to years of research and development, rigorous testing under MIL-STD-810H environmental standards, and ultimately, FDA clearance validating SEAL as a safe, effective, and portable hemostatic solution for external bleeding control.
Introducing SEAL: Simplicity That Saves Time
SEAL Hemostatic Wound Spray combines chitosan, a proven hemostatic biopolymer, with aerosol delivery. This allows users to spray directly onto a wound and rapidly form a protective barrier that helps control bleeding.
Unlike powders or dressings that require manual application or pressure, SEAL’s aerosol format makes it:
-
Fast: Deploys in seconds.
-
Clean: Minimal contact with the wound site.
-
Portable: Fits in trauma kits, duty belts, and field packs.
-
Versatile: Available in professional and over-the-counter (OTC) versions.
Because it is FDA-cleared for external use, SEAL can be removed easily with saline or sterile water, making it safe for continued medical treatment once professional care arrives.
