Summary
The Tandem t:slim X2 is rechargeable, has a touch screen, and can be updated on a home computer.
*Control IQ+ Technology now available for ages 2+
This system combines the Tandem t:slim x2 with the Dexcom G6 or G7 continuous glucose monitor (CGM) to automatically adjust insulin delivery in response to glucose trends. It's easy to use and allows bolus dosing directly from a compatible iOS or Android smartphone.
Components
Tandem t:slim X2 : Pump
Touch screen pump connects tubing to a small patch called an infusion set that attaches to the body.
Tandem t:slim X2 : Cartridge
Tubed insulin pumps contain a plastic reservoir that is manually filled with insulin and locked into the pump.
Tandem t:slim X2 : Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Tandem t:slim X2 : Controller
Compatible smartphone can be used to view and control insulin delivery using the t:connect app.
Control IQ with Dexcom : Pump
Touch screen pump connects tubing to a small patch called an infusion set that attaches to the body.
Control IQ : Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
Control IQ with Dexcom : Controller
t:slim pump receives CGM readings to automatically adjust basal insulin delivery via an infusion set. Compatible smartphone can be used to view and administer boluses via the t:connect app.
Control IQ : Infusion Set
An infusion set contains the thin plastic tubing that delivers insulin from the pump to the body.
Device Details
Overview
Smallest tubed pump. Modern interface resembles a smartphone but tubing may be visible.

Patient Considerations
Active Lifestyle
Exercise mode. Optional settings for exercise to adjust treatment ranges for activity with the press of a button. Pump is not waterproof.
Exercise Activity. Can manually increase target range to 140-160 mg/dl. Insulin decreases when Control IQ predicts CGM ≤140 mg/dl and increases when ≥ 160 mg/dl within 30 minutes. Autocorrections will still occur. Pump is not waterproof. CGM is waterproof.
Avoiding Highs and Lows
Precise dosing. Pumps allow different amounts of basal insulin at different times of day and very precise dosing.
Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a target blood glucose of 110 mg/dl. Auto-bolus is available once per hour to correct blood sugar above 180 mg/dl.
Comfort
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.
Low profile. Low profile/low maintenance sensor. Small tubed pump with the most infusion sets to pick from.
Easy Insulin Dosing
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.
Automatically adjusts dosing. Sensor integration allows for the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Basal in 0.001 increments, bolus in 0.01 increments. Extended bolus available.
Easy to Use
Rechargeable. Pump has a touch screen display and rechargeable battery.
Modern & flexible. Rechargeable and touchscreen pump. Sensor integrated with multiple devices in case you change up what you're using.
Fewer Fingersticks
Frequent finger-sticks are required.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
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.
Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed. Dexcom's built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
