The Fastest, Safest, Most Effective Prehospital Field Tourniquet
The Combat Application Tourniquet (C-A-T®) Generation 7
When we began work on the C-A-T® GEN 7 we considered every element
that defines a tourniquet designed for combat use. We challenged
ourselves to find the best, most forward-looking way possible to enhance
performance and maximize application success. But we didn’t do this
alone. Leveraging input from after action reviews, researchers, material
scientists and you, the end-user, we were able to create the most
advanced C-A-T® to date. Every component of the C-A-T® GEN 7 is
optimized for performance and reliability.
The C-A-T® GEN 7 has a single routing buckle system that (1) allows
for extremely fast application and effective slack removal (2)
Simplified training with single protocol directions for all
The patented C-A-T® is a true one-handed tourniquet proven to be 100%
effective by the U.S. Army’s Institute of Surgical Research.
C-A-T® Gen 7 Requirements Driven Enhancements:
Single Routing Buckle
- Faster application and effective slack removal resulting in
decreased blood loss and fewer windlass turns to achieve arterial
- Simplified training with single protocol directions for all applications
- Increased diameter for enhanced strength
- Aggressive ribbing for improved grip
- Bilateral beveled entry for rapid windlass lock
- Bilateral buttress for added strength
- Sonic welded to clip for constant contact
- Color changed to Gray for tactical considerations (Black C-A-T Only)
- Reinforced, beveled contact bar maintains the plate's integrity and decreases skin pinching
The Combat Application Tourniquet was initially fielded by USSOCOM in
2004 then fast followed by conventional forces in 2005. In the early
years of the Global War on Terrorism (GWOT) and prior to the
implementation of modern prefabricated tourniquets, the death rate from
extremity exsanguination was 23.3 deaths annually. After full
implementation, this number was reduced to 3.5 deaths per year, an 85%
decrease in mortality. In 2005 the Combat Application Tourniquet was
selected as one of the Army’s top 10 greatest inventions and is
recognized as one of the foremost advancements in pre-hospital care
during the GWOT with an estimated 1,850 lives saved.
Relentless comprehensive analysis of all deaths from extremity
hemorrhage has resulted in evidence-based tourniquet improvements. This
approach has yielded critical device improvements to include five
refinements in the design of the Combat Application Tourniquet over the
last decade. These enhancements were focused on maximizing the
effectiveness of the device while minimizing morbidity.
Continuous interface with end-users and researchers, literature
review and tourniquet applications in both real world and simulated high
stress tactical environments have made it clear, that despite
tremendous success, tourniquet knowledge gaps exist in the following
areas (1) single verses double routing of the band (2) Importance of
slack removal prior to engaging the windlass. Closing these gaps will be
accomplished through device enhancements, knowledge products and
The patented Combat Application Tourniquet® (C-A-T®) featuring the
proprietary red tip design and the mechanical advantage of a band within
a band has been the Official Tourniquet of the U.S. Army since 2005.
