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. 

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.

Patient Considerations

Active Lifestyle

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

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. 

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

Comfort

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

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

Easy Insulin Dosing

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

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.

Easy to Use

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

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

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 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.
