Description

Tourniquets are medical devices used to temporarily constrict blood flow to a limb, typically an arm or leg, during medical procedures such as blood collection or intravenous (IV) insertion. They are commonly made of elastic material or rubber and feature a fastening mechanism, such as a buckle or Velcro, to secure around the limb. Tourniquets are essential tools for creating a bloodless field, facilitating easier venipuncture and reducing the risk of excessive bleeding.
