Tourniquet * 4

A tourniquet is a medical device used to apply pressure to a limb or extremity in order to restrict blood flow, typically during medical emergencies or procedures. It is commonly used to control severe bleeding from a wound or during blood draws to make veins more prominent. Tourniquets come in various types, such as elastic, rubber, or mechanical versions with a buckle or clamp. They are essential in first aid, emergency care, surgery, and military medicine for quickly stopping blood loss or ensuring a stable environment for intravenous access.
