A TECHNIQUE WHICH CONSIDER THE CAPILLARY REFILL TIME CRT FOR SIMULATION OF SKIN DEFORMATION AND CHANGE OF SKIN COLOR CAUSED BY EXTERNAL FORCE

Abstract

One of the most significant application of human skin simulation technique is in preclinical medical practice. In many 3D modelling methods used in present, skin color of simulated objects is oftens not change at the point human body got external force automatically. However, actual observation shown that, the human skin color is changed a bit slower than the skin deformation under pressure. The delay time between skin deformation and color is based on human health condition such as blood pressure, ages, heart rate,… This arcticle demonstrates a technique for simulation of skin deformation and change of skin color caused by external force of solid objects. When being applied to a 3D model of a shocked emergency one-year old human, the proposed technique is proven to be effective and appropriate in representing capillary refill time (CRT) of human skin in real preclinical practices at medical training facilities in Vietnam.
