Unlike the continuous sensor alone, the closed-loop system requires no user input in response to reading from the monitor; the monitor and insulin pump system automatically delivers the correct amount of hormone calculated from the readings transmitted. The system is what makes up the artificial pancreas device. [27] [28]
Insulin pumps, cartridges, and infusion sets may be far more expensive than syringes used for insulin injection with several insulin pumps costing more than $6,000; necessary supplies can cost over $300. [3] Another disadvantage of insulin pump use is a higher risk of developing diabetic ketoacidosis if the pump malfunctions. [3]
A closed-loop system monitors blood glucose by CGM and sends data to an insulin pump for calculated delivery of insulin without user intervention. [13] A number of insulin pumps currently offer an "auto mode" however this is not yet a fully closed loop system.
Medtronic's (MDT) CE Marked advanced hybrid closed loop system, MiniMed 780G, is aimed at enhancing management of type 1 diabetes.

Pump and infusion set (catheter) placement Insulin basal bolus profile. Insulin pumps are drug delivery devices used to treat patients with type 1 and type 2 diabetes. The Minimed Paradigm REAL-Time and Continuous Glucose Monitoring (CGM) system, which received FDA clearance in 2006, uses tubing and a reservoir with rapid-acting insulin.
The purpose of an infusion set is to deliver insulin under the skin, fulfilling a similar function like an intravenous line. [1] It is a complete tubing system to connect an insulin pump to the pump user and as such includes a subcutaneous cannula, adhesive mount, quick-disconnect, and a pump cartridge connector.
