Research Abstract

Purpose of this study is to clarify generation mechanism of pressure ulcer in mechanical viewpoint and to improve efficiency of equipment for prevention of pressure ulcer. Mechanical analysis method to analyze deformation of capillary vessel inside of skin while compressing skin was proposed and validated by comparing with animal experiment. Finite-element model of human buttock for risk evaluation of occurring pressure ulcer was developed and verified by experiment. Furthermore, the buttock model was applied to mechanical evaluation of air mattress for prevention of pressure ulcer, and possibility of its optimization was clarified.
