Summary
Inhalable regular human insulin. Cartridges come in three doses: 4, 8, and 12-unit doses.
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
Body free of devices. Does not remain attached to the body.
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Avoiding Highs and Lows
Very short-acting. Absorbs quickly through the lungs to correct high blood sugar but requires attention to prevent 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.
Comfort
Many components. Have to carry multiple cartridges that can be bulky.
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
Easy Insulin Dosing
Less precise but easy dosing. Dosing may be less precise due to the inhaled method of dosing, but color-coded cartridges make dosing easier. Dosing can also be done based on small, medium, or large meals and can be administered 1-2 hours post meals.
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
Simple design. Whistle-like device for inhaling insulin.
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Fewer Fingersticks
Frequent finger-sticks are required.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Hideable. Small, discreet, and portable device that's not as noticeable as injections.
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 attached to local area with an armband or adhesive sleeve to be discreet when needed. Dexcom's built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
