Patient Considerations

Active Lifestyle

Exercise mode. Optional settings for exercise to adjust treatment ranges for activity with the press of a button. Pump is not waterproof. 

Waterproof. The pump, when connected to the cassette, has a rating of IP28, indicating protection from continuous immersion in water. The pump can tolerate immersion to depths of up to 12 feet (3.7 m) for 1 hour.

Avoiding Highs and Lows

Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.

Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.

Comfort

Smallest tubed pump. Small patch called an infusion set consists of a complete tubing system that attaches to the body. Tubed pumps have the most infusion sets to pick from. 

Low-profile. Low profile with an adhesive design that prevents the pump from catching on other objects. 

Easy Insulin Dosing

Customizable dosing. Bolus calculator available to help figure out doses. Offers smallest increments of basal insulin delivery. Basal in 0.001 increments, bolus in 0.01 increments.

Customizable. Can bolus from phone, smartwatch, or directly from the device without needing to be attached to your phone. The device also directly measures the volume (amount) and flow (speed) of insulin delivered with every micro-dose

Easy to Use

Rechargeable. Pump has a touch screen display and rechargeable battery. 

Watch compatible. The twiist AID system is the first FDA-approved AID system that can be directly controlled from an Apple Watch.

Fewer Fingersticks

Frequent finger-sticks are required. 

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Discreet. Smallest tubed pump with visible tubing. Ability to bolus directly on a compatible smartphone. Can be clipped to clothing or placed in a pocket to be discreet when needed. Touchscreen of pump looks like normal tech device.

Discreet. The pump is in two pieces - the top (algorithm and battery) and the bottom (insulin chamber and AVS technology)
