Summary

This system is the first automated insulin delivery system that combines the Tandem t:slim x2 with the Freestyle Libre 2 Plus continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends. It's easy to use and allows bolus dosing directly from a compatible iOS or Android smartphone. 

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

Patient Considerations

Active Lifestyle

Exercise Activity. Can manually increase target range to 140-160 mg/dl. Insulin decreases when Control IQ predicts CGM ≤140 mg/dl and increases when ≥ 160 mg/dl within 30 minutes. Autocorrections will still occur. Pump is not waterproof. CGM is waterproof. 

Waterproof. The pump and CGM are waterproof and can be worn for most exercises.

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 target blood glucose of 110 mg/dl. Auto-bolus is available once per hour to correct blood sugar above 180 mg/dl.

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. 

Comfort

Low profile. Low profile/low maintenance sensor. Small tubed pump with the most infusion sets to pick from.

Shorter tubing option. A shorter 5-inch tubing option for comfort on body. 

Easy Insulin Dosing

Automatically adjusts dosing. Sensor integration allows for the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Basal in 0.001 increments, bolus in 0.01 increments. Extended bolus available.

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. 

Easy to Use

Modern & no scanning required. Rechargeable and touchscreen pump. Sensor does not require scanning and sends minute-by-minute readings directly to the pump.

Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed. CGM has a built-in hypoglycemia safety alarm that alerts users when glucose is below 55 mg/dl and is always on.
