Device Classification

Product Code QFG Alternate Controller Enabled Insulin Infusion Pump
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 880.5730
Definition An Alternate Controller Enabled Insulin Infusion Pump (ace Insulin Pump) Is A Device Intended For The Infusion Of Insulin Into A Patient. The Ace Insulin Pump May Include Basal And Bolus Drug Delivery At Set Or Variable Rates. Ace Insulin Pumps Are Designed To Reliably And Securely Communicate With External Devices, Such As Automated Insulin Dosing Systems, To Allow Insulin Delivery Commands To Be Received, Executed, And Confirmed. Ace Insulin Pumps Are Intended To Be Used Both Alone And In Conjunction With Digitally Connected Medical Devices For The Purpose Of Insulin Delivery.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Chemistry devices follow this clearance model.
