Closed Loop System Design for Wireless Artificial Pancreas

Over the years diabetes has been a major cause of death due to its severe complications. Therefore, the artificial pancreas was introduced to help type 1 diabetic patients to automatically control their blood glucose level noninvasively by providing the substitute endocrine functionality of a healthy pancreas. The output voltage of the pulse oximeter was related to glucose using Microsoft Excel Regression Analysis Tool. The glucose level is then transmitted wirelessly through the radio frequency zigbee module. Afterwards, it was regulated according to the treat to range control algorithm within the sliding scale insulin protocol.

Although the artificial pancreas has managed to monitor blood glucose level and regulate it, its accuracy was found to be 89% compared to Accu-Chek glucometer. Not to mention its exceedingly inadequate size, time consumption and high expenses.
