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:
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.
By the end of this lesson, you will know:
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.
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.
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.
The Accu-Chek Rapid-D Link infusion set has a steel cannula. You can disconnect the headset (which has a 10 cm tail) from the 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.
Recommended infusion sites for any type of infusion set are:
Possible infusion sites include:
Your doctor or healthcare team will help you select your infusion site areas using a planned infusion site rotation guide.
The following are the steps for inserting the Accu-Chek FlexLink infusion set. Before unpacking your infusion set, wash and dry your hands throughly.
Proper preparation of your infusion site is vital to reducing the risks of infection and ensuring proper insulin absorption.
Choose and disinfect your infusion site as instructed by your doctor or healthcare team. Choose an infusion site away from your waistline, bones, any scar tissue, belly button and recent infuson sites. Let it dry completely before inserting your cannula. Rotate your infusion site regularly.
Remove the transparent protective cover from the cannula.
Be careful not to touch the cannula.
All head sets come with an adhesive to stick the infusion set to your body.
Remove both pieces of the adhesive backing from the self-adhesive.
If you have an allergy to the adhesive or need a head set without adhesive, then please consult your healthcare team.
Choose an infusion site at least 2.5 cm (1 inch) away from your navel / belly button / umbilical area and 5 cm (2 inches) away from previous infusion sites. Avoid your waistline, bones, bruises, scar tissue and sores.
Grasp a fold of skin.
Insert the introducer needle and soft cannula into the infusion site at a 90° angle (straight in one smooth motion).
Check pump is in STOP mode before inserting infusion set.
Carefully smooth the self-adhesive onto the skin and run your fingers over the self-adhesive to ensure good contact with the skin.
Hold the self-adhesive in place, gently press the side clips of the blue holder cap and pull it backwards from the cannula housing.
To remove the introducer needle, hold the cannula housing firmly to your body. Place one finger on the top of the cannula housing and withdraw the introducer needle in a straight manner using the introducer needle handle.
Remember to dispose of the introducer needle safely (into a needle / sharps container). Dispose of your sharps container according to local regulations.
