Summary:The purpose of this study is the development of a new tourniquet. The tourniquet is a device that stops blood flow by pneumatic pressure during orthopedic surgery. But, as doctor typically sets the pressure empirically, there is a problem that the patient has sequela. Although there is a possibility that it can be solved by adjusting the hemostatic pressure to this problem, since the systembecomes complicated, it was difficult to realize with the conventional air pressure. Therefore, we focused on EHD pump which can adjust pressure only by voltage which is impossible with conventional air pressure. In this study, we developed a tourniquet that can regulate the hemostatic pressure using this EHD pump.
