J0202-1-6 Analysis of Pathogenic of Pressure Ulcer by Using Cellular Automaton

Abstract

A super-aging society has led to an increase in number of bedridden elderly and wheelchair users. Because of this, recently the pressure ulcers have become a problem for us. In this research, the causes of pressure ulcers are simulated by cellular automaton method. It is considered that pressure, blood flow, and behavior of cells in the simulation of pressure ulcers. Pressure and blood flow are replaced with oxygen diffusion at each location, and the life of cell is connected by diffusion. Then the result of the simulation and the phenomenon of real pressure ulcers are coinside in the occurrence time of pressure ulcer. So they can be for used in the countermeasure of the pressure ulcers.
