Claims5
A tourniquet comprising:
- a base including at least first and second sections and having a cap attached to one of the first and second sections;
- a compression strap attached to said base and extending across said base, a portion of said compression strap being sandwiched between said base and the cap;
- a windlass handle having a strap aperture, said compression strap being threaded through said strap aperture and stitched to itself by a stitch pattern so as to form a strap loop, wherein the stitch pattern forms a triangle generally centered along a width of said compression strap where a base of the triangle extends transversely along the width of said compression strap generally parallel to said tourniquet handle;
- a locking strap extending across and attached to said cap;
- a handle stop engaging said locking strap such that said handle stop freely slides along said handle strap, said handle stop including a strap aperture that is sufficiently wide that at most only one of an upper boundary and a lower boundary of the strap aperture contact said locking strap at any given time;
- and
- a strap connector assembly including a buckle frame and a self-cinching sliding arm transversely extending from a first side of the buckle frame to a second opposing side of the buckle frame, a sliding arm being configured to slide along the buckle frame, said compression strap being threaded through said buckle frame, and a buckle connector attached to said compression strap configured to engage said buckle frame.
