Patient Considerations

Active Lifestyle

Water-resistant for up to 3 feet deep for 30 minutes and light on the body, does not get in the way of activity. 

Exercise mode. Optional settings for exercise to adjust treatment ranges for activity with the press of a button. Pump is not waterproof. 

Avoiding Highs and Lows

Optional glucose alerts for low and high glucose levels. Trend arrows show the direction glucose is heading, with the rate of change. 

Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.

Comfort

Lowest profile sensor and smallest adhesive (about the size of two stacked U.S pennies). 

Smallest 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

Sensor trends can be used for dose adjustment.

Customizable dosing. Bolus calculator available to help figure out doses. Offers smallest increments of basal insulin delivery. Basal in 0.001 increments, bolus in 0.01 increments.

Easy to Use

No scanning required. Minute-by-minute readings are sent directly to the mobile app. 

Rechargeable. Pump has a touch screen display and rechargeable battery. 

Fewer Fingersticks

Factory-calibrated sensor. Finger-sticks needed for backup only. 

Frequent finger-sticks are required. 

Privacy

Hypoglycemia safety alarm. Discreet size but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on. 

Discreet. Smallest tubed pump with visible tubing. Ability to bolus directly on a compatible smartphone. Can be clipped to clothing or placed in a pocket to be discreet when needed. Touchscreen of pump looks like normal tech device.
