Patient Considerations
Active Lifestyle
Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof.
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
Limited customizability. System integrates the Guardian Connect CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.
Comfort
Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors.
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
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
Customizable dosing. Bolus calculator available to help figure out doses. Basal and bolus in 0.05 increments.
Easy to Use
Simple design. Replaces regular insulin pen. No additional devices to add on.
Pump has a rechargeable battery that takes 30 minutes to charge, and lasts about a week.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Frequent fingersticks are still required.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
Discrete. The MiniMed Flex is small with visible tubing. Can be clipped to clothing or placed in a pocket to be discrete when needed.
