Components
Controller
Inpen connects to a mobile app and displays dosage information directly on a smart mobile device.
Cartridge
InPen is compatible with Humalog, Novolog, and Fiasp U-100 3.0 mL insulin cartridges.
Sensor
Sensor is inserted underneath the skin, either on the abdomen or arm. InPen is compatible with the Medtronic Guardian Connect sensor (left) or the Dexcom G6 sensor (right).
Glucometer
The meter measures the amount of sugar in the small sample of blood that is placed on the disposable test strip. Most CGMs require testing blood sugar with a meter to calibrate the CGM device daily.
Test Strips
The strips work with the glucose meters to “read” blood sugar levels. One box of test trips usually contains between 25-50 single use strips.
Lancets
Tiny needle called a lancet is used to poke the skin (on a finger or on your arm) to get a small sample of blood. The lancing device is packaged with the glucometer.

Patient Considerations
Active Lifestyle
Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof.
Must pause activity to check blood sugar.
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.
Less data. Meters don't give as much blood sugar data as sensors do and require a high level of engagement and effort to avoid highs and lows.
Comfort
Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors.
Meter supplies carried and requires visible blood.
Easy Insulin Dosing
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
Limited features. No info on blood sugar trends.
Easy to Use
Simple design. Replaces regular insulin pen. No additional devices to add on.
Large display. Device typically has large display numbers for easier readouts, and it's very simple to operate.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Frequent fingersticks are unavoidable.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
No attached device for blood glucose monitoring.
