device syringe insulin

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 

Traditional syringe and needle. The most affordable insulin delivery option.

Patient Considerations

Active Lifestyle

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

Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly.

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. 

Limited customizability. Requires a high level of engagement and effort to avoid highs and lows but can be paired with a CGM for improved blood sugar control. 

Comfort

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

Many components. Must carry insulin vials and large syringes but nothing attached to the body. 

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. 

Requires attention. You have to do the math to figure out your dose. Unable to adjust basal in real-time.

Easy to Use

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

Many steps. Requires effort to figure out doses and deliver insulin every single time you need it.

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Frequent finger-sticks are required. 

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 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.

Hideable. Vials and syringes can be hidden when not in use but very visible when in use. Frequent injections are unavoidable.
