Tandem t:slim X2 Cartridge

Insulin delivery is easy with the Tandem t:slim X2 cartridge. These cartridges are specifically designed for use with the Tandem t:slim X2 insulin pump. Each disposable insulin pump cartridge holds 3mL of rapid-acting insulin. This equals about 300 units or 2-3 days worth of insulin. Simply fill the cartridge with your rapid-acting insulin of choice, slide the cartridge into your pump, and follow the instructions on your pump’s screen to get started. The Tandem t:slim X2 cartridge is compatible with U-100 Humalog and U-100 NovoLog. It is not approved for use with other types of insulin.

This insulin pump cartridge has a pouch inside of the cartridge that holds the insulin. Tandem’s Micro-Delivery Technology™ ensures you never waste insulin. It draws small amounts of insulin from the pouch into a micro-delivery chamber for more accurate delivery.

When filling your Tandem t:slim X2 cartridge, make sure the pump is not attached to your body. With clean hands, remove the cap from the insulin pump cartridge. Sterilize the insulin vial and insert the syringe. Slowly inject insulin into the cartridge, carefully avoiding air bubbles. Next, prime the cartridge. Tap the cartridge gently and slowly push the plunger to get rid of any bubbles. Next, attach the infusion set to the cartridge. Prime the infusion set to ensure there is no air in the tubing. Turn off the insulin pump and insert the cartridge using the t:lock connector. Secure the cartridge into a locked position and turn on your insulin pump. Follow the instructions on the screen.
