A combat<unk>  commonly used by combat medics (military environment) and EMS (civilian environment). A<unk>  is a device that is used to apply pressure to a limb or extremity in order to stop the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation. A<unk>  is also used by the phlebotomist to assess and determine the location of a suitable vein for venipuncture. Proper application of a<unk>  will partially impede venous blood flow back toward the heart and cause the blood to temporarily pool in the vein so the vein is more prominent and the blood is more easily obtained. The<unk>  is applied three to four inches above the needle insertion point and should remain in place no longer than one minute to prevent hemoconcentration. A simple<unk>  can be made from a stick and a rope (or leather belt), but the use of makeshift<unk> s has been reduced over time due to their ineffectiveness compared to a commercial and professional<unk> . This may stem the flow of blood, but side effects such as soft tissue damage and nerve damage may occur.
