Device for the automatic insulin or glucose infusion in diabetic subjects, based on the continuous monitoring of the patient's glucose, obtained without blood withdrawal

摘要

A saline solution is pumped through a semi-permeable, hollow- fiber circuit implantable in a living body. A sensor determines the concentration of glucose in the solution. A microcomputer unit controls the supply of insulin and glucose to the body on the basis of the glucose concentration measurements. The hollow fibers form a filter through which only low molecular weight molecules may pass.
