Tourniquets help save lives by constricting blood flow to a traumatized limb thereby preventing excess blood loss in a medical emergency. Existing tourniquets are primarily designed for use by medical professionals and combat personnel and such as the military and law enforcement agencies. Application of these types of tourniquets can be painful and physically challenging, in part, due to a narrow width of the tourniquet band and a difficult to operate tightening apparatus. These design flaws make available tourniquets both sup-optimal for use by professionals and poorly suited for widespread use by the civilian population.

An improved tourniquet design that can be easily used by both civilians and military professionals

This technology is a tourniquet based on Civil War era combat tourniquets and is designed to be less painful to wear and easier to apply than available models. Specifically, this tourniquet has a wider band and thus causes less discomfort when applied to the affected extremity. It is also equipped with a tightening apparatus that is easier to operate and provides improved mechanical advantage during application. This tourniquet is capable of stopping all blood flow to upper and lower extremities and is designed to be compatible with single-handed application. These features produce a tourniquet that is easy to apply and minimizes physical discomfort and is ideal for both military professionals and the civilian population.

Applications

  • Control of life threatening upper extremity hemorrhage for either civilian or military trauma use
  • Control of life threatening lower extremity hemorrhage for either civilian or military trauma use

Advantages

  • Easy to apply
  • Easy to tighten
  • Easy to store
  • More comfortable than traditional tourniquets
  • Design allows for one-handed self-application
