Meter
MiniMed Flex
Summary
Good to have. Tried and true. Backup or day to day. Fingersticks required.
The MiniMed Flex is a tubed insulin pump system designed to automate insulin delivery using SmartGuard™ technology and the Simplera Sync sensor. Boluses can be delivered directly through the MiniMed app, while customizable settings help support glucose management throughout the day.
Components
Glucometer
The meter measures the amount of sugar in the small sample of blood that is placed on the disposable test strip. Most CGMs require testing blood sugar with a meter to calibrate the CGM device daily.
Test Strips
The strips work with the glucose meters to “read” blood sugar levels. One box of test trips usually contains between 25-50 single use strips.
Lancets
Tiny needle called a lancet is used to poke the skin (on a finger or on your arm) to get a small sample of blood. The lancing device is packaged with the glucometer.
Controller
Pump receives CGM readings and automatically adjusts insulin delivery. Data from the pump and CGM viewable on compatible smartphones.
Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body. Optional Medtronic Extended™ Infusion set (up to 7-day wear) available.
Reservoir
Tubed insulin pumps contain a plastic reservoir or cartridge that is manually filled with insulin and locked into the pump. ExtendedTM Reservoir MMT-342, 10PK. 3.0 ml (300 units).
Pump
Pump connects tubing to a small patch called an infusion set that attaches to the body.

Patient Considerations
Active Lifestyle
Must pause activity to check blood sugar.
Exercise mode. Optional settings for exercise to adjust treatment ranges for activity with the press of a button. Pump is waterproof for up to 8 feet for 105 minutes.
Avoiding Highs and Lows
Less data. Meters don't give as much blood sugar data as sensors do and require a high level of engagement and effort to avoid highs and lows.
Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.
Comfort
Meter supplies carried and requires visible blood.
Small tubed pump. Small patch called an infusion set consists of a complete tubing system that attaches to the body. Tubed pumps have the most infusion sets to pick from.
Easy Insulin Dosing
Limited features. No info on blood sugar trends.
Customizable dosing. Bolus calculator available to help figure out doses. Basal and bolus in 0.05 increments.
Easy to Use
Large display. Device typically has large display numbers for easier readouts, and it's very simple to operate.
Pump has a rechargeable battery that takes 30 minutes to charge, and lasts about a week.
Fewer Fingersticks
Frequent fingersticks are unavoidable.
Frequent fingersticks are still required.
Privacy
