Abstract: An adjustable tourniquet device is set forth wherein a predetermined length of surgical elastomeric tubing is doubled upon itself and subsequently knotted along the length to form a series of loops terminating in a final knot. The loops may be equally spaced or of decreasing opening size by varying the spacing between the sequential knots. The device is positionable about a victim's limb whereupon the device is extended about the limb and the final knot is positioned through one of the loops to provide adequate pressure on the limb to limit circulation consistent with tourniquet use. The decreasing loops of the tourniquet provide an extra measure of adjustment in use by enabling incrementally smaller diametrical application of the tourniquet.
