Study Summary
The study described within this protocol is designed to test a single hormone closed-loop algorithm for managing blood glucose in type 1 diabetes using insulin only and a new device for measuring glucose continuously in the immediate vicinity of subcutaneous insulin delivery. Subjects will undergo one all day closed loop study using insulin only. The closed loop insulin only system includes a Dexcom G5 transmitter, a Nexus 5 smart phone and two Tandem tslim pumps connected to two Pacific Diabetes Technologies glucose sensing cannulas. The closed loop system will be started after G5 2 hour sensor start-up with an IV catheter for frequent blood withdrawal for 10 hours.
Primary Outcome
Assess the mean absolute relative difference for the PDT CGM/insulin infusion system based on all reference YSI venous blood glucose values.
Interventions
- DEVICE Artificial Pancreas Control system (APC)
- DEVICE Pacific Diabetes Technologies CGM Insulin Infusion system
