TOURNIQUET

A Tourniquet is a medical device that temporarily restricts blood flow in a limb by applying pressure. It is commonly used during blood draws, surgeries, or emergencies to control bleeding. The tourniquet is typically a band or strap that is tightened around the arm or leg, reducing blood flow to the area and making veins more visible and easier to access for procedures like venipuncture. In emergency settings, tourniquets can be life-saving by controlling severe bleeding until further medical treatment is available.
