Design and development of insulin delivery system prototype

The manual method to insulin delivery for diabetes mellitus require significant efforts from clinical stand point and not guarantee of an optimal performance. The insulin delivery system is a low cost portable, automated insulin delivery pump which is used by diabetics to administer insulin as and when they require it at regular intervals. An insulin delivery system for diabetes patients, which is used for the continuous subcutaneous insulin infusion (CSII) therapy. The purpose of design & development of insulin delivery system is to deliver precise and accurate insulin infusion rate continuously to the patient using continuous glucose monitoring system (CGMS) data & providing cost effective solution along with flexible lifestyle. The ergonomic design is developed considering Type 1 and Type 2 diabetes patient model. The proposed control strategy is evaluated at different CGMS values, which correspond to realistic meal profiles and workouts performed by patient. The system is a safety-critical embedded system which estimates and control the infusion rate of insulin based upon relative proportional control law. Insulin delivery system is an indigenous concept with highly reliable control of micro-fluidic delivery. Infusion delivery system is used to deliver extremely small volume of liquid in predefined time duration, at a constant flow rate, therefore the system find applications in research and development related to biotechnology, bioengineering, chemical laboratories and in analytical instruments.
