Tandem Mobi
Dexcom G7
Summary
The Tandem Mobi is the smallest durable automated insulin delivery system available in the U.S. that can be fully controlled by a mobile device. The pump is equipped with an on-pump button for users to bolus insulin directly from the pump if they don’t want to do it from their phone. This system is combined with the Dexcom continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends.
*Compatiblilty with Dexcom G7 now available
Dexcom G7 is a low-profile, all-in-one glucose sensor/transmitter and warms up faster than other CGMs on the market. This sensor lasts for 10 days and sends real-time glucose readings to a compatible smartphone app or directly on an Apple Watch. No finger pricks or scanning is needed. Optional low and high-blood sugar notifications are available for this system.

Patient Considerations
Active Lifestyle
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Avoiding Highs and Lows
Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a set blood glucose target.
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
Low profile and low maintenance sensor application.
Easy Insulin Dosing
Automatically adjusts dosing. Sensor integration allows the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Manual bolus button is available for quick dosing without a phone.
Real-time data and alerts make dose adjustment easier.
Easy to Use
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
No scanning required. Readings are sent directly to the mobile app every 5 minutes.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone.
