Abstract
Crush Syndrome (referred to in the rest of this document as CS) was killed many victims at Great Hanshin Earthquake, but there is no viable countermeasure even now. Therefore, we have proposed and researched Life-saving Robot. This time, we experimented about the Mechanism of CS Preventer to be equipped on that Robot. This Mechanism has a purpose that preventing the onset of CS until victim is carried by the Robot to doctors waiting at a safe area. This Mechanism compress the groin by pressure materials, stem the femoral vein blood flow to prevent reperfusion. Furthermore, femoral artery and vain are adjoining, the flow velocity measurements of posterior tibial artery was used as an indicator of the femoral vein ischemia. A result of the experiment, the mechanism of CS preventer showed high Circulation blocking rate more than a thigh avascularization and a groin compression by palm. Furthermore, it was suggested that the requirement of a pressure value to ischemia have individual differences with age and body fat percentage.
