An automated insulin delivery (AID) system works by automatically adjusting insulin delivery based on real-time glucose levels. It's a closed-loop system designed to mimic a healthy pancreas.
Here's a breakdown:
Components of an AID System
An AID system comprises three primary components that work together seamlessly:
- Continuous Glucose Monitor (CGM): The CGM tracks your sugar levels every few minutes through a small sensor inserted under the skin. It provides continuous, real-time glucose readings.
- Insulin Pump: The insulin pump delivers insulin under the skin.
- Smart Algorithm: This is the brain of the system. The algorithm links the CGM and insulin pump, enabling them to communicate and make automated adjustments to insulin delivery.
How the System Operates
The system operates in a continuous cycle:
- Glucose Monitoring: The CGM continuously monitors glucose levels and transmits this data to the smart algorithm.
- Data Analysis: The smart algorithm analyzes the glucose data, predicts future glucose levels, and determines the appropriate insulin dosage.
- Insulin Adjustment: Based on the analysis, the algorithm instructs the insulin pump to adjust the insulin delivery. The pump can either increase, decrease, or suspend insulin delivery as needed to maintain target glucose levels.
- Feedback Loop: This process repeats continuously, creating a feedback loop that helps regulate blood glucose levels automatically.
In summary, an automated insulin delivery system uses real-time glucose data from a CGM and a smart algorithm to automatically adjust insulin delivery via an insulin pump, aiming to keep glucose levels within a target range.
