Hemostatic devices are medical tools designed to control bleeding during surgical procedures or after injuries. They work by promoting blood clotting or mechanically compressing blood vessels to stop blood flow. Common types include hemostatic agents, clamps, and tourniquets. These devices are crucial in emergency medicine and surgery, as uncontrolled bleeding can lead to serious complications. By effectively managing hemorrhage, hemostatic devices help improve patient outcomes and reduce the risk of shock or death. Their use is essential in various settings, from hospitals to battlefield medicine.
