Mechanical tourniquet apparatus and method of use

A tourniquet apparatus comprising:

• a tourniquet body having a length sufficient to encircle a limb, thereby moving the tourniquet apparatus to an engaged configuration;
• a constriction assembly engaged with said tourniquet body, said constriction assembly being configured to bias a first location of said tourniquet body towards a second location of said tourniquet body when the tourniquet apparatus is in the engaged configuration, thereby moving the tourniquet apparatus towards a constricted configuration;
• and
• a carriage engaged with said tourniquet body, a compressive element of said carriage extending between said first and second locations of said tourniquet body when the tourniquet apparatus is in the constricting configuration, thereby facilitating application of a relatively uniform radial compression force around an entire diameter of the limb such that blood flow in the limb is restricted.
