loop device v4

Summary

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

Loop is a DIY (do-it-yourself) system. It takes some work to set up but allows people to think about diabetes less by automating basal insulin delivery based on predicted glucose levels. This system can be used with the Dexcom G6 and the Omnipod or Medtronic pumps. Information about DIY Loop can be found on the Loop or Riley Link websites.

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.

Loop : Pump

Loop : Pump

The system is compatible with Omnipod (left) or Medtronic (right) pumps. Both options can be applied anywhere on the body that is comfortable.

Loop : Sensor

Loop : Sensor

Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.

DIY Loop : Transmitter

DIY Loop : Transmitter

RileyLink allows the pump and sensor to communicate. It is only required if a Medtronic pump is used.

Loop : Controller

Loop : Controller

Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via an Omnipod or Medtronic pump.

Device Details

Overview

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

This is a DIY (do-it-yourself) system that needs significant setup. It has the most flexibility in settings and device options. It also depends on a third device called a "Riley Link" to communicate between sensor, phone, and pump. 

Affordability and Access

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

$$$$
Supplies can be covered for Omnipod or Medtronic pumps and Dexcom. Price range; $0-$8,574 to start and 0-$300/month. iPhone, app, and Riley link are not covered and must be set up independently. Riley link price range; $135-$165.

Data Monitoring Options

Limited Options
Data is available directly on the device. Some meters may be compatible with the Tidepool data management system. 

Yes
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 can be viewed on an iPhone. 

Duration and Storage

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

3-day pump 10-day sensor
Sensors last 10 days and transmitters last 90, and work at 50ºF – 108ºF. Pods or pump reservoirs last for up to 72 hrs and work from 40ºF – 104ºF.

Patient Considerations

Active Lifestyle

Must pause activity to check blood sugar.

Automatic responses. Can set custom blood sugar targets and insulin and carb sensitivities based on type of activity. App automatically responds to blood sugar changes during activity. *Medtronic option is not waterproof. Omnipod option is fully waterproof. 

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 but extra device. Low profile/low maintenance sensor. The RileyLink is an extra device that must be carried.

Easy Insulin Dosing

Limited features. No info on blood sugar trends.

All settings are completely customizable. Can bolus from phone or smartwatch. Can operate “open-loop” where the user must enact insulin delivery based on recommendations or “closed-loop” where modifications to insulin delivery are automatically delivered.

Easy to Use

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

Difficult set-up but easy to use. Software makes most dosing decisions. Requires many parts. Can be difficult to set up. 

Fewer Fingersticks

Frequent fingersticks are unavoidable.

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

No attached device for blood glucose monitoring. 

Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available. *Medtronic pump has tubing. Omnipod is most hideable pump option (no tubes or separate controller needed).
