Patient Considerations

Active Lifestyle

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

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

Avoiding Highs and Lows

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

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

Comfort

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. 

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

Easy Insulin Dosing

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.

Sensor trends can be used for dose adjustment.

Easy to Use

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

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

Fewer Fingersticks

Frequent finger-sticks are required. 

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

Privacy

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.

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