Esmarch bandage
The Esmarch bandage (also known as Esmarch's bandage for surgical haemostasis or Esmarch's tourniquet), in its modern form, is a narrow (5 to 10 cm (2.0 to 3.9 in) wide) soft rubber bandage that is used to expel venous blood from a limb (exsanguinate) that has had its arterial supply cut off by a tourniquet. The limb is often elevated as the elastic pressure is applied.
