Mechanical Analysis of Generation Mechanism of Pressure Ulcer and Optimal Design of Apparatus for Prevention of Pressure Ulcer

本研究旨在从力学角度阐明压疮的产生机制，提高压疮预防设备的使用效率。提出了一种分析皮肤受压时毛细血管内部变形的力学分析方法，并与动物实验进行了对比验证。建立了人体臀部压疮发生风险评估的有限元模型，并进行了实验验证。并将臀部模型应用于气垫预防压疮的力学评价，明确其优化的可能性。

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.
