Medical devices, not accessories

What “accepted” means for a tourniquet

A tourniquet is a medical device. Each of the four above is manufactured by a company registered with the U.S. Food and Drug Administration and is listed with the FDA as a medical device under 21 CFR Part 807. Each also appears on the CoTCCC recommended devices list, which is the Department of Defense’s evidence-based reference for battlefield trauma care. The program accepts tourniquets from that list that a member of the public can apply with the training the STOP THE BLEED® class provides.

Only these four may be packed in a STOP THE BLEED® kit. A licensee cannot substitute another tourniquet, and a tourniquet sold on its own under the STOP THE BLEED® name must be one of the four. Counterfeit copies of these devices are common in online marketplaces and can fail under load; buy from a licensed seller, and if the price or packaging seems off, look more closely.

These notes are only here to help you tell the four apart. They are not instructions, and none of the four is recommended over the others. Put a tourniquet on the way your STOP THE BLEED® class taught you and the way the directions on the package say. Find a class near you.
