According to physiologic character of insulin secretion of normal body, one new design has been advanced. It can provide insulin with both pulsed and slow-released ways, and imitate separately two completely different forms of insulin secretion. Through extracorpored experiment, one parallel model has been set up. One function is similar to post-cibum largely and quickly pulsed insulin secretion, other one is continuous and stable micro-secretion in 24 hours. The theoretical base for researching furtherly the open implanted artificial pancreas (pump) depends on the result of this article.
