水肿是细胞外液在皮下组织中过度积聚的一种情况，老年人下肢水肿的患病率很高。有一种叫俯仰试验的方法作为评价水肿情况的方法，但它是主观评分，难以定量评价。因此，本研究的目的是利用粘弹性模型来表达水肿的力学特性，以定量评价水肿。在点蚀试验中，在恒定压力下施加压缩10秒，并使用压痕的深度进行评估。在本研究中，我们使用了一个二黏一弹的三元粘弹性模型，该模型也被用于评估皮肤的粘弹性。黏弹性参数是用激光位移计测量水肿受压时位移的时间变化来估计的。通过使用粘弹性参数，考虑到不仅压痕，而且回归方法也会有所不同，可以对目前无法评估的水肿进行评估。在本文中，我们报告了使用水肿模的测量结果。
Edema is a condition in which extracellular fluid accumulates excessively in the subcutaneous tissue, and the prevalence of lower limb edema is high in the elderly. There is a method called pitching test as a method to evaluate the condition of edema, but it is subjective scoring, and it is difficult to evaluate quantitatively. Therefore, the purpose of this study is to express the mechanical properties of edema using a viscoelastic model with the aim of quantitative evaluation of edema. In the pitting-test, compression is applied at a constant pressure for 10 seconds, and evaluation is performed using the depth of the indentation. In this study, we use a three-element viscoelastic model with two viscosity and one elasticity, which is also used to evaluate the viscoelasticity of the skin. The viscoelastic parameter is estimated by measuring the temporal change in displacement when pressure is applied to the edema using a laser displacement meter. By using the viscoelasticity parameter, it is considered that not only the indentation but also the return method will be different, and it may be possible to evaluate edema that could not be evaluated so far. In this paper, we report the measurement results using the edema phantom.
