Participant Flow

This study was put on hold after two participants completed two weeks of the intervention (BIAP) due to technical issues. Due to multiple factors this study has not restarted since and a decision has been made to terminate it.

Bio-inspired Artificial Pancreas (closed-loop system) with a fixed bolus calculator BiAP: The bio-inspired artificial pancreas (BiAP) system uses a control algorithm based on a mathematical model of beta-cell behaviour derived from physiological experiments, carried out by other groups, which have demonstrated how the beta cells in the pancreas produce insulin in people without diabetes. Utilising the data from these experiments it has been possible to implement the behaviour of the beta cell in software and we have used a simulator with 200 virtual patients to demonstrate the safety and efficacy of the algorithm. The data from the simulator have previously been published. The BiAP algorithm is implemented on a miniature silicon microchip within a portable handheld device, which interfaces the components of the artificial pancreas.
