Fundamentals of Closed Loop Insulin Delivery

A closed loop systems as a continuous beed back loop. The continuous glucose monitor measures interstitial glucose levels every one to five minutes. Thi data feed into a control algorytthm that calculates thee approvate insulin dose and directs the pump to deliver it. The allegimthm may hosted on a dedisativated controller, a smartphone application, or direclyn on thee pump itself. Depending on thee desere of automation, systemes are classifid aid aid.

As of 2025, thee most widely used FDA- approved hybrid closed loop systems included thee Medtronic MiniMed 780G with SmartGuard technology, the Tandem t: slem X2 witch Control- IQ, and the Insulet Omnipod 5.
