Touch simplicity®

We spent thousands of hours talking to people living with diabetes, doctors, and diabetes educators. The result is the world’s first touch-screen pump, ranked #1 for overall satisfaction, ease of training, and customer support for the past two years.1


So durable

The t:slim® Insulin Pump is ultrastrong. Its aluminum body is very durable and light, and the touch screen is made of high-grade, shatter-resistant glass. Plus, the t:slim Pump is watertight1, so you don’t have to worry if it accidentally gets wet.

So preferred

The t:slim Pump has consistently ranked #1 by pump users in overall satisfaction.2 This reflects the focus that Tandem Diabetes Care places on all aspects of using and owning an insulin pump, from cutting edge design, ease of use, expert training, unique and powerful features, professional 24-hour customer support, and interactive data management software.

So small, so discreet

The t:slim Pump is the slimmest pump on the market and has a sleek, modern design. A patented pumping mechanism and the latest rechargeable battery technology allow it to pack a 300-unit reservoir and up to seven days of power into its slim, sleek case. The smooth, compact design allows it to easily slip into a pocket or be worn discreetly under clothing.

So advanced

The t:slim Pump was built using the most advanced technology, with your lifestyle and safety in mind. Tandem's patented Micro-Delivery® technology delivers insulin in the tiniest increments available. The t:slim Pump also incorporates familiar technology such as an integrated micro-USB port for convenient charging and fast data transfer speeds.

A lot of pump in a little package.
