Summary

The InPen system enhances management with multiple daily injections because it tracks data in real-time and offers personalized dosing recommendations. This system combines the Guardian Connect CGM with smart insulin pens for more time in range. 

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

Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof. 

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

Avoiding Highs and Lows

Limited customizability. System integrates the Guardian Connect CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day. 

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 InPen and pen needles. CGM is attached to the body and requires more tape than other sensors. 

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

Easy Insulin Dosing

Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin. 

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. Replaces regular insulin pen. No additional devices to add on. 

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

Fewer Fingersticks

2 daily finger-sticks are needed to calibrate the sensor. 

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone. 

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.
