Fewer needles. More freedom.

For convenience and ease of use, the t:flex® Insulin Pump just fits. It is designed to help make your day-to-day insulin management as simple as possible by giving you more freedom and flexibility than you get with injections.

Dosing made simple

Touchscreen technology makes the t:flex Pump simple to learn and simple to use. The bright, color touch screen lets you conveniently deliver insulin and view your settings.

Up to 3 days of insulin delivery

Don’t let the small size of the t:flex Pump fool you.  This little pump has the largest insulin capacity available — up to 480 units. This means you can get up to 3 days of insulin1 delivery with fewer interruptions for cartridge changes than with other pumps.

So small, so discreet

The t:flex Pump looks more like a smart phone than a medical device, so it's easy to use it in public without drawing attention.


Safe and secure

The t:flex Pump was designed with your safety in mind:

  • Touchscreen safety lock guards against unintended use 
  • Innovative Micro-Delivery® technology prevents your pump from unintentionally delivering insulin from the reservoir
  • Easy-to-hear alerts and alarms have adjustable volume and vibrate mode
  • It's simple enough for a family member or friend to learn (in case you ever want their help)

Built to last

The t:flex Pump is ultrastrong. Its aluminum body is very durable and light, and the touchscreen is made of high-grade, shatter-resistant glass. Plus, it's watertight2, so you don’t have to worry if your pump accidentally gets wet.

A lot of pump in a little package.
