2P1-B07 The trajectory control of the lower limbs movement assistant robot aimed for deep-vein thromboprophylaxis(Medical Robotics and Mechatronics)

Abstract

When the human keep the same postures for a long time, e.g., after operation, sit on bed with same posture, there is a possibility to cause deep-vein thrombosis (DVT) of which the most serious complication is that the clot could dislodge and travel to the lungs and death. In order to prevent DVT, we have been developing a prototype of the lower limbs movement assistant robot which forcibly moves a foot so as to improve blood circulation. We compared the bloodstream using the developed robot by changing the trajectories of foot movement patterns. In this paper, we verify trajectory pattern to promote the bloodstream.
