人工生物胰腺是一种在动势脉分流术中用于糖尿病患者的可植入的装置,它包括从循环血中分离出来分泌胰岛素的胰岛细胞,而循环血是靠一个半透膜防止免疫排斥。我们最近提出一种能从流体机制的观点来阐述这个装置工作的模型,而且该模型能估价扩散与超滤对葡萄糖和胰岛素物质传递过程的作用。实验证明,沿血液通道压力逐渐下降。物 The artificial biological pancreas is an implantable device for diabetics in dynamic arterial shunt, which includes islet cells that secrete insulin from circulating blood, which circulates through a semi-permeable membrane to prevent immune rejection . We recently proposed a model that describes the operation of this device from a fluid mechanistic perspective and the model evaluates the effects of diffusion and ultrafiltration on the glucose and insulin transport processes. Experiments show that the pressure along the blood channel gradually decreased. Things
