  • Introduction

    As you learned in the pump basics Training Module, the pump delivers insulin from the cartridge to the body with an infusion set. The infusion set generally includes three parts:

    1. Transfer set/tubing with luer lock connection
    2. A Head set that houses the cannula
    3. Protective cap

    There are three different types of Accu-Chek infusion sets to choose from. You may wish to try the different types to see what you prefer. You can also talk to your doctor and healthcare team for advice. This lesson provides a quick review on choosing an infusion set and the best infusion sites.

    Summary of functions
  • What are the advantages of soft cannulas?

    Some people prefer soft cannulas to steel ones because they find them more comfortable to wear. They do not feel the cannula when bending, twisting or exercising. The soft cannula infusion set is inserted with an introducer needle. After insertion, the introducer needle is removed and the soft cannula remains in the tissue beneath the skin.

    This type of infusion set needs to be changed every 48-72 hours.

  • Accu-Chek soft cannula products

    The Accu-Chek TenderLink infusion set has a soft cannula that is inserted at a 20-45° angle. The Accu-Chek FlexLink infusion set has a soft cannula that can be inserted at a 90° angle. The Accu-Chek FlexLink infusion set can be inserted manually or with the Accu-Chek LinkAssist automatic insertion device, that allows automatic virtually pain-free insertion hard to reach infusion sites.

  • What are the advantages of steel cannulas?

    Steel cannulas are a little thinner. Some people prefer steel cannulas because they find them more comfortable to insert as well as there is less chance of the cannula kinking during the insertion process and use compared to a soft cannula manually inserted.

    This type of infusion set needs to be changed every 24-48 hours.

  • Length of cannula and transfer set/tubing

    Make sure you have the right length of tubing to reach from the pump to the infusion site. If the pump is on a part of the body which will move, choose slightly longer tubing to allow for the movement.

    You have now learned about the different infusion sets. Now, let's discuss infusion sites.

    Choose a short cannula if you have low body fat or a long cannula if you have high body fat.
