TK-4: Advanced One-Handed Tourniquet

For men and women in combat environments, immediate first aid can be the difference between life and death. Severe injuries in inaccessible areas creates the need for immediate trauma care. The H&H TK-4 tourniquet is designed specifically for this purpose. Its one-handed application provides a simple to use device that makes stopping arterial bleeding easy and direct for injuries ranging from combat trauma to accidental amputation.

TK-4 features a newly developed woven elastic textile band (3” wide by 40” long) that provides incredible strength and flexibility. With two steel hooks fastened steadfast (three thick hog rings per S-Hook) to both ends of the elastic band, and packaged in a small, vacuum-sealed pouch. TK-4 is the perfect solution for any kind of injury involving arterial bleeding.

TK-4 has been deployed by the US Marine Corps, US Special Forces, and numerous law enforcement and emergency services.

In April 2007, the Navy Experimental Diving Unit compared several of the leading self-applied tourniquets on the market including the H&H TK-3 and TK-4 models. Their research found that both H&H products ranked at the top for overall efficiency and product usability. Download the report here.

TK-4L: One-Handed Tourniquet for Legs

H & H’s TK-4 tourniquet, in 2007 tests by the U.S. Naval Experimental Diving Unit, demonstrated successful arterial occlusion capabilities with the exception of the application of the tourniquet at the top of the leg. In fact, ALL of the tested tourniquets failed 33% of the time when applied at the top of the leg. This is unacceptable.

When tourniquets are applied at this point on the leg over materials such as a uniform, as is normal, the tourniquets were either not strong enough to fully pressure the area or the users could not or would not place maximum force on the tourniquet.

In order to allow the user to put maximum pressure wit the tourniquet, H & H modified the TK-4 to create the TK-4L to give the user the ability to apply the maximum capable force on lower extremities.

The TK-4L updates the TK-4 design by putting a tension fixture at one end of the strap. The added aluminum tension fixture results in the ability to apply maximum manual force to the strap and increase the blood loss stoppage capability of the strap.
