Closed-Loop Insulin Delivery
A diabetes technology system that connects a CGM, an insulin pump, and an algorithm that can adjust insulin delivery.
Plain English
Closed loop means the sensor and pump communicate through an algorithm.
Why It Matters After 40
It is a real medical device category, not just a consumer AI feature.
What To Do With It
Use this term to understand device conversations. Device selection and settings belong with a diabetes care team.
Human Utility
- Know what the term means before uploading data into an AI tool.
- Separate explanation from medical interpretation.
- Bring trend data and context to the appointment instead of one isolated number.
Proof Structure
FDA recognizes the device category
FDA describes artificial pancreas device systems as linking CGM and insulin infusion through a computer-controlled algorithm.
