Research on rescue through robot have been in progress when dangerous environment such as natural disasters and war situation. Various types of injuries can occur in this rescue situation, and research on rescue robots capable of first aid such as injection, oxygen supply, and hemostasis is under way to increase the survival rate of injured persons. Among the first-aid measures mentioned above, hemostasis can reduce the risk of death not only a direct cause such as hyper-bleeding but also indirect cause such as shock and temperature drop due to bleeding. In this paper, we describe the gadget for hemostasis based on the concept design necessary for development of hemostatic gadget.
