The Guardian™ 4 sensor (MMT-7040) is part of the compatible Medtronic automated insulin dosing (AID) system. The sensor converts small amounts of glucose from the interstitial fluid under the skin into an electronic signal. The sensor uses that signal to provide sensor glucose (SG) values to a compatible Medtronic AID system. Designed for individuals aged seven years and older, this innovative sensor effortlessly monitors glucose levels by transforming traces of glucose from the interstitial fluid beneath the skin into precise electronic signals. These signals are then utilized by the CGM system to provide real-time glucose readings. The Guardian Sensor 4 is specifically crafted to assist in the ongoing management of diabetes. It serves as a supplemental tool, enhancing but not replacing the critical data obtained from standard blood glucose monitoring devices. Its design prioritizes accuracy and ease, supporting informed diabetes management decisions based on continuous, real-time data.
