Closed Loop Insulin Therapy in Type 1 Diabetics Based on Blood Microdialysis, Online Sensors and an eMPC Algorithm

Completed

• Conditions: Type 1 Diabetes

• Registration Number: NCT00535483
• Lead Sponsor: Medical University of Graz

Brief Summary

The EU funded project CLINICIP (Closed Loop Insulin Infusion for Critically Ill Patients) aims to develop a low-risk monitoring and control device which allows maintaining metabolic control in intensive care units. A system will be developed comprising three subsystems: a body interface for the delivery of biofluids, biosensors for the determination of glucose concentration in these biofluids and an adaptive control algorithm that generates advice and thus represents a decision support system with respect to insulin infusion rate to establish glycaemic control in critically ill patients. Within a closed loop system, intensified insulin treatment will make use of the calculations leading to external regulation of glucose.

It is the aim of this study to evaluate the feasibility to establish glycaemic control in type 1 diabetic subjects over a period of 30 hours by manually combining these three - previously tested - subsystems (ABS System, extracorporeal online glucose sensor and a laptop-based computer algorithm).
