DIY Loop
CeQur Simplicity Patch
Summary
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.
Cequr Simplicity is a thin and simple insulin delivery patch for mealtime and correction insulin. The 3-day wearable patch doses two units of insulin with every squeeze of the buttons on either side of the device. Users can fill their CeQur Simplicity patch with 100-200 units of rapid-acting insulin. This device is a hybrid between injections and an insulin pump to allow for discreet dosing without the need for programming or multiple injections.
FDA-approved for both type 1 and type 2 diabetes in people 21 years of age and older.
Components
Controller
Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via an Omnipod or Medtronic pump.
Transmitter
RileyLink allows the pump and sensor to communicate. It is only required if a Medtronic pump is used.
Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
Pump
The system is compatible with Omnipod (left) or Medtronic (right) pumps. Both options can be applied anywhere on the body that is comfortable.
Applicator
Patch uses a thin, flexible cannula inserted just under the skin to deliver insulin. Push-button applicator allows patch to be placed on the body in one step.
Reservoir
Fill reservoir is enclosed with the Patch and used to manually fill the Patch with insulin.
Patch
Wearable insulin patches come with reservoirs and directions for application. They can be applied on the abdomen.
Device Details
Overview
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.
Convenient, discreet, and simple to use.
Affordability and Access

Patient Considerations
Active Lifestyle
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.
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly, but the device is water resistant.
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.
Limited customizability. System requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day. If you need basal (background) insulin, you’ll still need to take it in addition to wearing the CeQur Simplicity.
Comfort
Low-profile but extra device. Low profile/low maintenance sensor. The RileyLink is an extra device that must be carried.
Free of tubing. Patches do not have tubing and they're less bulky than traditional insulin pumps but it must be worn in areas that are easy to reach for insulin dosing.
Easy Insulin Dosing
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. Squeezing the buttons on either side of the device delivers insulin in two-unit increments for dosing insulin for meals and correction.
Easy to Use
Difficult set-up but easy to use. Software makes most dosing decisions. Requires many parts. Can be difficult to set up.
Simple with few steps. Patch is replaced every 3 days with insulin administered at the click of a button.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Frequent finger-sticks are required.
Privacy
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).
Hideable. Thinnest and lightest patch pump that's not as noticeable as injections.
