Abstract
Since the strict control of the blood sugar level of the diabetic patient is essential to prevent the diabetic complications exemplified by the microangiopathies, artificial pancreas, cosisting of the monitor of blood sugar level and automatic injector of insulin coupled with feed back system, is great concern for the treatment of diabetic patients.
In this investigation, blood sugar level is measured with the voltage subtraction circuit by subtraction of the oxygen electrode current from that of the oxygen electrode with glucose-oxydase.
Proportional relationship is recognized between sensor current and glucose concentration from 0 to 250mg/dl, and paralell relationship in the glucose tolerance curves is observed between them in animal experiments.
