Patient Considerations

Active Lifestyle

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.

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

Avoiding Highs and Lows

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

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

Comfort

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

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. 

Easy Insulin Dosing

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

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.

Easy to Use

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

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

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Frequent finger-sticks are required. 

Privacy

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

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.
