tourniquets

A tourniquet is a device used to control severe bleeding from an arm or leg by tightly tightening around the limb to stop blood flow. It is typically a band or strap, sometimes with a buckle or windlass, applied above the injury site. Proper application can prevent dangerous blood loss and buy time until medical help arrives. However, it should be used carefully and as a last resort, because applying it too tightly or for too long can cause tissue damage or nerve injury. Training and correct technique are essential for safe and effective use.
