1. A tourniquet, comprising:
a support structure having a platform defining a first strap slot proximate a first end of a back plate;
a first arm depending from a top surface of the back plate proximate a second end of the back plate and adjacent a first side of the back plate;
a second arm depending from the top surface of the back plate proximate the second end of the back plate, opposite the first arm and adjacent a second side of the back plate, the second arm forming a capture hook;
a gate member having a first end attached to a distal end of the first arm and a second end in biased engagement with an under side of the capture hook of the second arm;
a windlass defining a longitudinal slot extending therethrough; and
a strap having a first strap portion having a length sufficient to extend around an extremity and extending from proximate the second end of the back plate and having a free end portion, the free end portion configured to be inserted through the first strap slot and pulled to tighten the strap around the extremity relative to the support structure, a second strap portion having a first end extending from the first strap portion proximate the second end of the back plate, the second strap portion extending over the platform, through the longitudinal slot of the windlass, through the first strap slot, and under the platform, the second strap portion having a second end fixedly attached to an underside of the first strap portion a distance from the second end of the back plate to form a loop;
whereby winding the windlass relative to the support structure causes the second strap portion to twist between the windlass and the support structure to effectively shorten the second strap portion to thereby tighten the first strap portion around an extremity to which the first strap portion is configured to be attached; and
whereby one end of the windlass can be positioned between the first and second arms and retained by the gate member when the windlass has been wound relative to the support structure.
