Dose Safety Hybrid Closed Loop and Fully Automated Closed Loop Artificial Pancreas Device in CRC

The objective of this study is to test two different operating modes of the latest version of the Dose Safety artificial pancreas system (APS), the Dose Safety Controller (DSC version 2.3), in a population of subjects with type 1 diabetes (TID) in a hospital CRC setting. The first mode is the Fully Automated Closed Loop (FACL) mode, in which all insulin delivery is directed by the controller and the second mode is the Hybrid Closed Loop (HCL) mode, in which insulin delivery is a hybrid between controller directed delivery and user directed insulin delivery. There will be two study arms: HCL and FACL. No comparisons will be made between the two arms.
