loop device v4

Summary

Traditional syringe and needle. The most affordable insulin delivery option. 

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

Syringe and Vial : Bolus Insulin

Syringe and Vial : Bolus Insulin

Bolus (fast-acting) insulin vial for meal time or high blood sugar correction.

Syringe and Vial : Basal Insulin

Syringe and Vial : Basal Insulin

Basal (long-acting) insulin vial for steady release of insulin that helps control blood sugar between meals, and overnight.

Syringe and Vial : Needles

Syringe and Vial : Needles

Classic syringes with plunger used to fill insulin for injection

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

Nothing on the body when not in use but very visible when dosing. 

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

$$$$
Syringes are available worldwide in pharmacies or DME without prescription. Price Range: $0-$300/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.

Duration and Storage

28 Days 
Open vials can be stored at room temperature (not above 80º F) for up to 28 days. Unopened vials should be stored in the refrigerator (36ºF - 86ºF.) 

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

Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly.

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

Limited customizability. Requires a high level of engagement and effort to avoid highs and lows but can be paired with a CGM for improved blood sugar control. 

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

Comfort

Many components. Must carry insulin vials and large syringes but nothing attached to the body. 

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

Easy Insulin Dosing

Requires attention. You have to do the math to figure out your dose. Unable to adjust basal in real-time.

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

Many steps. Requires effort to figure out doses and deliver insulin every single time you need it.

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

Fewer Fingersticks

Frequent finger-sticks are required. 

Factory-calibrated sensor. Fingersticks needed for backup only.

Privacy

Hideable. Vials and syringes can be hidden when not in use but very visible when in use. Frequent injections are unavoidable.

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).
