Summary

Good to have. Tried and true. Backup or day to day. Fingersticks required.

The twiist AID system was cleared by the FDA for use with CGMs that have received FDA designation as integrated continuous glucose monitors (iCGMs). As the twiist AID system gets closer to commercial availability, Sequel Med Tech will publicize the list of compatible CGM

*Recently FDA approved for people with type 1 diabetes ages 6 and up.

Components

Generic Meter : Lancets

Generic Meter : 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.

Generic Meter : Test Strips

Generic Meter : 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.

Meter : Glucometer

Meter : 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.

twiist  : Pump

twiist : Pump

Pump can be worn with a pump clip, adhesive patch or in a pocket.

twiist  : Controller

twiist : Controller

Pump is controlled by the twiist app on an iPhone. Data from both the pump and CGM are viewable on the twiist app Home Screen.

Twiist  : Infusion Set

Twiist : Infusion Set

An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.

Device Details

Overview

Good to have. Tried and true. Backup or day to day. Finger-sticks required.

This system automatically adjusts insulin delivery according to continuous glucose monitor (CGM) readings and predicted blood sugar levels. It is the first FDA-approved AID system with Apple Watch compatibility.

Affordability and Access

$$$$
Most accessible. Available over the counter at all Pharmacies. Price range; $0-$200/month depending on insurance coverage.

$$$$
No insurance coverage data. Anticipated to be provided through Pharmacy.

Compatible with Tidepool - a web-based diabetes data management system. 

Data View Options

Yes
Data may be viewed directly on the device. Some meters contain a built-in USB connection that allows information to be uploaded to a data management system. 

Yes
Data is stored and can be viewed directly from the twiist app on the mobile device (iPhone), and can be linked to an Apple Watch for viewing data as well.

 

Duration and Storage

Daily
Meters can last several years with battery changes/charging, they're used daily and work between 65ºF-86°F

Patient Considerations

Active Lifestyle

Must pause activity to check blood sugar.

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

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.

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

Comfort

Meter supplies carried and requires visible blood.

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

Easy Insulin Dosing

Limited features. No info on blood sugar trends.

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

Large display. Device typically has large display numbers for easier readouts, and it's very simple to operate.

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 fingersticks are unavoidable.

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

No attached device for blood glucose monitoring. 

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