Scope and Objectives

The overall objective is to develop an effective artificial pancreas system for Type-1 diabetic patients, especially for the Indian population.

Deliverables

The aim of this project is to develop two effective artificial pancreas prototypes for Type-1 diabetic patients, especially aimed at the Indian patients. In the first option, the system will consist of commercially available continuous glucose monitoring sensor and insulin pump, where the communication will happen via a cellular phone. The control algorithm will be embedded in the cellular phone by developing a specific App. As a parallel alternative, an insulin pump will also be developed indigenously, which will directly communicate with the continuous glucose monitoring sensor. In both options, a smart control algorithm based on advanced predictive and feedback control theory will be embedded to compute the required insulin dosage. The algorithm will use an Indian patient-specific model and hence both options are expected to perform better for Indian T1DM patients as compared to other such systems

Scientific Output

1) Collecting data about the glucose sensitivity in Type-1 diabetic patients in India using ethically and scientifically approved medical procedures. (2) Using this population-specific data to develop a suitable mathematical model. (3) Using this mathematical model to determine the insulin requirement based on advanced control theory. (4) Developing an embedded platform using medically certified continuous glucose monitoring sensors and the insulin pump with a cellular phone in the loop. (6) Indigenously designing and developing an insulin pump in parallel and integrating it using sensors. (7) Conducting supervised trials on subjects to prove the efficacy of control algorithms and indigenously developed insulin pump.

Results and outcome till date

1) Glucose sensitivity tests on Indian T1DM patients have started and the corresponding data is being collected successfully. 2) The physiological parameters are being estimated successfully using various well established mathematical techniques. 3) We have developed an Android app which receives the data from CGMS through a device known as LimiTTer. 4) The indigenously developed Mark-1 prototype insulin pump was developed and tested in the first phase. In the second stage, various design modification has been identified and are being implemented.

Societal benefit and impact anticipated

1) Insulin pumps available in the market are very costly and are not affordable to the common public. The prototype which we are developing will be low cost and durable. 2) The automatic insulin delivery will be customized specifically for the Indian T1DM subjects. 3) In the conventionally available insulin pump in the market, the T1DM patient has to manually adjust many settings thus departing from closed blood glucose control concept. Our artificial pancreas system will be designed to have a minimal human intervention.

Next steps

1) Development and implementation of advanced closed-loop feedback control ideas. 2) Embedding the control and estimation logic into the cellular phone and addressing communication and security of data transmission issues. 3) Design and development of the indigenous Mark-2 prototype of the insulin pump, including identifying the controller hardware, porting of the control algorithm on the embedded platform, user interface software coding, and communication protocol between the pump and the CGM sensor.
