Summary

The purpose of this study is to verify an automated system of blood glucose control in Type I Diabetics. The automated system consists of the investigational Artificial Pancreas Control software (APC), two blood glucose sensors, and two hormone pumps, one for delivering insulin to lower blood sugar, and the second for delivering glucagon to raise blood sugar. The blood glucose sensors relays information to the Artificial Pancreas software, which uses the Adaptive Proportional Device algorithm to determine the rate of insulin and glucagon infusion by the hormone pumps. In prior studies, the Adaptive Proportional Device algorithm has been verified, but required manual input into the computer and hormone pumps. This study differs in that it uses a fully automated system under the control of the Artificial Pancreas Control software. The importance of this change is that it is the next step to enable outpatient use of automated, closed loop blood glucose control.

Conditions

  • Type I Diabetes Mellitus

Interventions

DEVICE

Artificial Pancreas Control Software

This master controller software is used in conjunction with two subcutaneous continuous glucose monitoring systems and two Omnipod pumps, one for administering aspart insulin (NovoLog) and one for administering glucagon (GlucaGen), to control blood glucose levels. The insulin and glucagon infusion rates are determined by an automated version of the Adaptive Proportional Derivative (APD) insulin and glucagon control algorithm.
