The SOF Tourniquet Gen 4 is comprised of high-strength, lightweight alloy components. Its design allows the tourniquet to slide over a limb or, if the limb is trapped, the tourniquet can be rapidly disconnected and reconnected around the limb without rethreading the strap. The Gen 4 still maintains its true 1.5” tourniquet strap, providing a wider compression pattern than most standard tourniquets. The wider compression pattern results in additional arterial compression and increased patient comfort.
