Glucose Management

The hybrid closed-loop insulin delivery system, a form of “artificial pancreas,” is composed of an insulin pump, a standardized algorithm, and a continuous glucose monitor. The system streamlines insulin delivery by connecting continuous glucose monitor data with an insulin pump and an algorithm to drive basal insulin delivery. The hybrid closed-loop insulin delivery system, approved by the Food and Drug Administration in 2016 for children older than 7 years, is a major improvement in the management of type 1 diabetes. The purpose of this article is to educate school nurses about the components of the hybrid closed-loop insulin delivery system, the relevance to care, and the future direction of blood glucose management.

Main Components

This paper presents the design of an embedded control system for insulin pump. The insulin pump is an integrated component in any closed loop insulin delivery system for type 1 diabetes. The pump consists of three main components: micro-needles, insulin reservoir(syringe), and piezoelectric (PZT) linear servo motor. The actuated syringe has an injection back pressure that resists the linear motion of the driving PZT motor. This back pressure acts as a disturbance and leads to in accurate position and consequently an imprecise insulin dosage. Therefore, a highly precise positioning control on the pump is required to control the insulin dosage and to maintain the blood glucose level in its safe range. The proposed controller is designed using fuzzy logic as a nonlinear controller to compensate any non-modeled nonlinear ities in the system.The embedded controller for the PZT motor can be implemented using FPGA or microcontroller chip. This controller acts as a slave and responds to its master controller which controls the complete closed loop insulin delivery system.
