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 transmitter when submerged in 1 meter of water for up to 30 minutes and must be within 25 feet of the connected smart device.
Avoiding Highs and Lows
Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.
On-body vibration alerts when blood glucose levels are higher or lower than the set range. 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.
Longest-lasting sensor fits comfortably under the skin. Minor procedure is required. Least likely to have compression lows.
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.
Predictive alerts make insulin dosing easier by tracking high and low trends.
Easy to Use
Rechargeable. Pump has a touch screen display and rechargeable battery.
Minor procedure. Requires insertion by a physician during a medical visit.
Fewer Fingersticks
Frequent finger-sticks are required.
2 daily finger-sticks are needed to calibrate the sensor.
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.
Somewhat discreet. Tiny sensor is implanted under the skin, so the user can be discreet when needed. Ability to see sugar on watch or phone. Sensor not movable on body and requires regular meter use.
