摘要
提出了多孔胃管洗胃的方程及其拟合方程.把多孔胃管的终端划分为连续的含孔微元,用离散分析研究了各微元流体在洗胃冲吸中的方程,从模拟洗胃实验得出各孔流速的约束条件,为胃管的工程估算与合理开孔提供数学依据.
Mathematical equations and fitting equation for gastric lavage with porous stomachtube are presented.The terminal of porous stomach-tube is divided into successive microelements containing holes,equations of every microelement in the process of gastric lavage is researched with discrete analysis.Flow velocity constraints are given by results of the simulation gastric lavage experiment.The equations provide the mathematical basis for engineering estimation and rational opening in the stomach-tube.
