Patient Considerations

Active Lifestyle

Body free of devices. Does not remain attached to the body.

Waterproof when submerged in water and must be within range of the feet of the receiver or mobile device.

Avoiding Highs and Lows

Very short-acting. Absorbs quickly through the lungs to correct high blood sugar but requires attention to prevent lows. 

Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change. 

Comfort

Many components. Have to carry multiple cartridges that can be bulky. 

Smaller size. The sensor is small and flat, and no overtape is required. Simplera’s adhesive is made from an anti-lint material that prevents sweat and water from reaching the sensor.

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. 

Real-time data and alerts make dose adjustment easier. The device can be integrated with the Medtronic InPen, which offers a bolus calculator based on carb ratios, meal estimations, the amount of insulin on board, and fixed dosing regimens

Easy to Use

Simple design. Whistle-like device for inhaling insulin.

No scanning is required. Readings are sent directly to the mobile app every 5 minutes.

Fewer Fingersticks

Frequent finger-sticks are required. 

Factory-calibrated sensor. Finger sticks needed for backup only.

Privacy

Hideable. Small, discreet, and portable device that's not as noticeable as injections. 

Discreet. Small, flat shape and ability to see sugar on a watch or phone.
